Finding Land for US Wind Farms Might Be Easier Than We Thought

The Washington Post reports that wind turbines "only take up five percent of the land where they've been built, new research shows." The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology. This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm. The new study highlights that turbines and existing human development, such as agriculture, cannot only share the same area, but also that building wind farms where there are already roads and other infrastructure could help reduce impacts on the land. "Clever siting, use of existing infrastructure, multiple use of landscapes — all these things ... can really contribute to solutions in areas where wind power is acceptable to the local people," said Sarah Jordaan, the study's principal investigator. Historically, planning studies for wind farms have often assumed that turbines would disturb all the land at the site and leave the area unusable for anything else, said Jordaan, an associate professor in the department of civil engineering at McGill University. The study's findings provide a more accurate accounting of how much land is needed for wind farms, she added.

A New Battery Warns Parents if Their Child Has Swallowed It

A new battery from Energizer comes with "color alert technology" to alert parents if their child has swallowed one. When the coin lithium battery comes into contact with saliva, it activates a blue dye "so parents and caregivers know that medical attention could be required," reports the New York Times. The battery also features more secure packaging and a nontoxic bitter coating. From the report: The new coin lithium battery features more secure packaging, a nontoxic bitter coating to discourage swallowing and "color alert technology" that activates a blue dye when the battery comes into contact with moisture, like saliva, so parents and caregivers know that medical attention could be required. The new battery was announced in a video last week by Energizer and Trista Hamsmith, whose 18-month-old daughter died after swallowing a button battery from a remote control. Ms. Hamsmith founded a nonprofit organization focused on children's safety, successfully advocated for legislation, known as Reese's Law, that requires a secure compartment of the batteries in products that use them as well as stronger warning labels on all packaging, and is now working to make the batteries themselves safer. Ingested coin or button batteries result in thousands of emergency hospital visits each year, according to the U.S. Consumer Product Safety Commission, which notes that "the consequences of a child swallowing a battery can be immediate, devastating and deadly." "A button cell battery can burn through a child's throat or esophagus in as little as two hours if swallowed," according to the agency. Secure packaging and bitter coatings for batteries have long existed, but "the massive breakthrough here is the color alert technology, which helps give caretakers that indicator that something has happened," Jeff Roth, the global category leader for batteries at Energizer, said in an interview on Wednesday. "The most significant part about this is getting help early in the process," he said. "That's really what the color alert technology allows the family to do."

China Launches World's Largest Electric Container Ship

AmiMoJo shares a report from Tech Times: China has reached a major landmark in green transportation with the launch of the world's largest fully electric container ship. Developed and manufactured by China Ocean Shipping Group (Cosco), the vessel is now operating a regular service route between Shanghai and Nanjing, aiming to reduce emissions significantly along its journey. The Greenwater 01, an all-electric container ship, is positioning itself to be a shipping industry pioneer. Equipped with a main battery exceeding 50,000 kilowatt-hours, the vessel can accommodate additional battery boxes for longer voyages. These battery boxes, each containing 1,600 kilowatt-hours of electricity and similar in size to standard 20-foot containers, provide flexibility in extending the ship's travel range. With 24 battery boxes onboard, the Greenwater 01 can complete a journey consuming 80,000 kilowatt-hours of electricity. This is equivalent to saving 15 tons of fuel compared to a standard container ship, highlighting the efficiency of electric propulsion systems. According to Cosco, the vessel can reduce CO2 emissions by 2,918 tons per year, which is equivalent to taking 2,035 family cars off the road or planting 160,000 trees.

America's Wind Power Production Drops For the First Time In 25 Years

An anonymous reader quotes a report from Bloomberg: U.S. wind power slipped last year for the first time in a quarter-century due to weaker-than-normal Midwest breezes, underscoring the challenge of integrating volatile renewable energy sources into the grid. Power produced by turbines slipped 2% in 2023, even after developers added 6.2 gigawatts of new capacity, according to a government report Tuesday. The capacity factor for the country's wind fleet -- how much energy it's actually generating versus its maximum possible output -- declined to an eight-year low of 33.5%. Most of that decline was driven by the central US, a region densely dotted with turbines. Wind is a key component of the effort to cut carbon emissions, but the data highlights the downside of relying on intermittent energy sources tied to the effects of global weather. Last year's low wind speeds came during El Nino, a warming of the equatorial Pacific that tends to weaken trade winds. La Nina, the Pacific cooling pattern that dominated in 2022 and is poised to return later this year, usually has the opposite effect. The U.S. Energy Information Administration shared the findings in a report published earlier today.

A Coal Billionaire is Building the World's Biggest Clean Energy Plant - Five Times the Size of Paris

An anonymous reader shared this report from CNN: Five times the size of Paris. Visible from space. The world's biggest energy plant. Enough electricity to power Switzerland. The scale of the project transforming swathes of barren salt desert on the edge of western India into one of the most important sources of clean energy anywhere on the planet is so overwhelming that the man in charge can't keep up. "I don't even do the math any more," Sagar Adani told CNN in an interview last week. Adani is executive director of Adani Green Energy Limited (AGEL). He's also the nephew of Gautam Adani, Asia's second richest man, whose $100 billion fortune stems from the Adani Group, India's biggest coal importer and a leading miner of the dirty fuel. Founded in 1988, the conglomerate has businesses in fields ranging from ports and thermal power plants to media and cements. Its clean energy unit AGEL is building the sprawling solar and wind power plant in the western Indian state of Gujarat at a cost of about $20 billion. It will be the world's biggest renewable park when it is finished in about five years, and should generate enough clean electricity to power 16 million Indian homes... [T]he park will cover more than 200 square miles and be the planet's largest power plant regardless of the energy source, AGEL said. CNN adds that the company "plans to invest $100 billion into energy transition over the next decade, with 70% of the investments ear-marked for clean energy."

Plunge in Storage Battery Costs Will Speed Shift to Renewable Energy, Says IEA

"In less than 15 years, battery costs have fallen by more than 90%," according to a new report from the International Energy Agency, "one of the fastest declines ever seen in clean energy technologies." And it's expected to get even cheaper, reports Reuters: An expected sharp fall in battery costs for energy storage in coming years will accelerate the shift to renewable energy from fossil fuels, the International Energy Agency (IEA) said on Thursday... The total capital costs of battery storage are due to tumble by up to 40% by 2030, the Paris-based watchdog said in its Batteries and Secure Energy Transitions report. "The combination of solar PV (photovoltaic) and batteries is today competitive with new coal plants in India," said IEA Executive Director Fatih Birol. "And just in the next few years, it will be cheaper than new coal in China and gas-fired power in the United States. Batteries are changing the game before our eyes." [...] The global market for energy storage doubled last year to over 90 gigawatt-hours (GWh), the report said... The slide in battery costs will also help provide electricity to millions of people without access, cutting by nearly half the average electricity costs of mini-grids with solar PV coupled with batteries by 2030, the IEA said. The Los Angeles Times notes one place adopting the tech is California: Standing in the middle of a solar farm in Yolo County, [California governor] Newsom announced the state now had battery storage systems with the capacity of more than 10,000 megawatts — about 20% of the 52,000 megawatts the state says is needed to meet its climate goals. Although Newsom acknowledged it isn't yet enough to eliminate blackouts...

California Is Grappling With a Growing Problem: Too Much Solar

An anonymous reader quotes a report from the Washington Post: In sunny California, solar panels are everywhere. They sit in dry, desert landscapes in the Central Valley and are scattered over rooftops in Los Angeles's urban center. By last count, the state had nearly 47 gigawatts of solar power installed -- enough to power 13.9 million homes and provide over a quarter of the Golden State's electricity. But now, the state and its grid operator are grappling with a strange reality: There is so much solar on the grid that, on sunny spring days when there's not as much demand, electricity prices go negative. Gigawatts of solar are "curtailed" -- essentially, thrown away. In response, California has cut back incentives for rooftop solar and slowed the pace of installing panels. But the diminishing economic returns may slow the development of solar in a state that has tried to move to renewable energy. And as other states build more and more solar plants of their own, they may soon face the same problems. Curtailing solar isn't technically difficult -- according to Paul Denholm, senior research fellow at the National Renewable Energy Laboratory, it's equivalent to flipping a switch for grid operators. But throwing away free power raises electricity prices. It has also undercut the benefits of installing rooftop solar. Since the 1990s, California has been paying owners of rooftop solar panels when they export their energy to the grid. That meant that rooftop solar owners got $0.20 to $0.30 for each kilowatt-hour of electricity that they dispatched. But a year ago, the state changed this system, known as "net-metering," and now only compensates new solar panel owners for how much their power is worth to the grid. In the spring, when the duck curve is deepest, that number can dip close to zero. Customers can get more money back if they install batteries and provide power to the grid in the early evening or morning. The change has sparked a huge backlash from Californians and rooftop solar companies, which say that their businesses are flagging. Indeed, Wood Mackenzie predicts that California residential solar installations in 2024 will fall by around 40 percent. Some state politicians are now trying to reverse the rule. "Under the CPUC's leadership California is responsible for the largest loss of solar jobs in our nation's history," Bernadette del Chiaro, the executive director of the California Solar and Storage Association, said in a statement referring to California's public utility commission. But experts say that it reflects how the economics of solar are changing in a state that has gone all-in on the technology. [...] To cope, [California's grid operator, known as CAISO] is selling some excess power to nearby states; California is also planning to install additional storage and batteries to hold solar power until later in the afternoon. Transmission lines that can carry electricity to nearby regions will also help -- some of the lost power comes from regions where there simply aren't enough power lines to carry a sudden burst of solar. Denholm says the state is starting to take the steps needed to deal with the glut. "There are fundamental limits to how much solar we can put on the grid before you start needing a lot of storage," Denholm said. "You can't just sit around and do nothing." Further reading: The Energy Institute discusses this problem in a recent blog post. Since 2020, the residential electricity rates in California have risen by as much as 40% after adjusting for inflation. While there's been "a lot of finger-pointing about the cause of these increases," the authors note that the impact on rates is multiplied when customers install their own generation and buy fewer kilowatts-hours from the grid because those households "contribute less towards all the fixed costs in the system." These fixed costs include: vegetation management, grid hardening, distribution line undergrounding, EV charging stations, subsidies for low income customers, energy efficiency programs, and the poles and wires that we all rely on whether we are taking electricity off the grid or putting it onto the grid from our rooftop PV systems. "Since those fixed costs still need to be paid, rates go up, shifting costs onto the kWhs still being bought from the grid."

AI Needs So Much Electricity That Tech Companies Are Getting Into Energy Business

An anonymous reader shares a report: To accommodate tech companies' pivots to artificial intelligence, tech companies are increasingly investing in ways to power AI's immense electricity needs. Most recently, OpenAI CEO Sam Altman invested in Exowatt, a company using solar power to feed data centers, according to the Wall Street Journal. That's on the heals of OpenAI partner, Microsoft, working on getting approval for nuclear energy to help power its AI operations. Last year Amazon, which is a major investor in AI company Anthropic, said it invested in more than 100 renewable energy projects, making it the "world's largest corporate purchaser of renewable energy for the fourth year in a row."

What Happened After Amazon Electrified Its Delivery Fleet?

Bloomberg looks at America's biggest operator of private electrical vehicle charging infrastructure: Amazon. "In a little more than two years, Amazon has installed more than 17,000 chargers at about 120 warehouses around the U.S." — and had Rivian build 13,500 custom electric delivery vans. Amazon has a long way to go. The Seattle-based company says its operations emitted about 71 million metric tons of carbon dioxide equivalent in 2022, up by almost 40% since Jeff Bezos's 2019 vow that his company would eventually stop contributing to the emissions warming the planet. Many of Amazon's emissions come from activities — air freight, ocean shipping, construction and electronics manufacturing, to name a few — that lack a clear, carbon-free alternative, today or any time soon. The company has not made much progress on decarbonization of long-haul trucking, whose emissions tend to be concentrated in industrial and outlying areas rather than the big cities that served as the backdrop for Amazon's electric delivery vehicle rollout... Another lesson Amazon learned is one the company isn't keen to talk about: Going green can be expensive, at least initially. Based on the type of chargers Amazon deploys — almost entirely midtier chargers called Level 2 in the industry — the hardware likely cost between $50 million and $90 million, according to Bloomberg estimates based on cost estimates supplied by the National Renewable Energy Laboratory. Factoring in costs beyond the plugs and related hardware — like digging through a parking lot to lay wires or set up electrical panels and cabinets — could double that sum. Amazon declined to comment on how much it spent on its EV charging push. In addition to the expense of the chargers, electric vehicle-fleet operators are typically on the hook for utility upgrades. When companies request the sort of increases to electrical capacity that Amazon has — the Maple Valley warehouse has three megawatts of power for its chargers — they tend to pay for them, making the utility whole for work done on behalf of a single customer. Amazon says it pays upgrade costs as determined by utilities, but that in some locations the upgrades fit within the standard service power companies will handle out of their own pocket. The article also includes this quote from Kellen Schefter, transportation director at the Edison Electric Institute trade group (which worked with Amazon on its electricity needs). "Amazon's scale matters. If Amazon can show that it meets their climate goals while also meeting their package-delivery goals, we can show this all actually works."

Data Centers Are Turning to an Old Source of Power: Coal

The Washington Post reports on a new situation in Virginia: There, massive data centers with computers processing nearly 70 percent of global digital traffic are gobbling up electricity at a rate officials overseeing the power grid say is unsustainable unless two things happen: Several hundred miles of new transmission lines must be built, slicing through neighborhoods and farms in Virginia and three neighboring states. And antiquated coal-powered electricity plants that had been scheduled to go offline will need to keep running to fuel the increasing need for more power, undermining clean energy goals... The $5.2 billion effort has fueled a backlash against data centers through the region, prompting officials in Virginia to begin studying the deeper impacts of an industry they've long cultivated for the hundreds of millions of dollars in tax revenue it brings to their communities. Critics say it will force residents near the [West Virginia] coal plants to continue living with toxic pollution, ironically to help a state — Virginia — that has fully embraced clean energy. And utility ratepayers in the affected areas will be forced to pay for the plan in the form of higher bills, those critics say. But PJM Interconnection, the regional grid operator, says the plan is necessary to maintain grid reliability amid a wave of fossil fuel plant closures in recent years, prompted by the nation's transition to cleaner power. Power lines will be built across four states in a $5.2 billion effort that, relying on coal plants that were meant to be shuttered, is designed to keep the electric grid from failing amid spiking energy demands. Cutting through farms and neighborhoods, the plan converges on Northern Virginia, where a growing data center industry will need enough extra energy to power 6 million homes by 2030... There are nearly 300 data centers now in Virginia. With Amazon Web Services pursuing a $35 billion data center expansion in Virginia, rural portions of the state are the industry's newest target for development. The growth means big revenue for the localities that host the football-field-size buildings. Loudoun [County] collects $600 million in annual taxes on the computer equipment inside the buildings, making it easier to fund schools and other services. Prince William [County], the second-largest market, collects $100 million per year. The article adds that one data center "can require 50 times the electricity of a typical office building, according to the U.S. Department of Energy. "Multiple-building data center complexes, which have become the norm, require as much as 14 to 20 times that amount." One small power company even told the grid operator that data centers were already consuming 59% of the power they produce...

California Exceeds 100% of Energy Demand With Renewables Over a Record 30 Days

An anonymous reader quotes a report from Electrek: In a major clean energy benchmark, wind, solar, and hydro exceeded 100% of demand on California's main grid for 30 of the past 38 days. Stanford University professor of civil and environmental engineering Mark Z. Jacobson has been tracking California's renewables performance, and he shares his findings on Twitter (X) when the state breaks records. Jacobson notes that supply exceeds demand for "0.25-6 h per day," and that's an important fact. The continuity lies not in renewables running the grid for the entire day but in the fact that it's happening on a consistent daily basis, which has never been achieved before. At the two-week record mark, Ian Magruder at Rewiring America made this great point on LinkedIn: "And what makes it even better is that California has the largest grid-connected battery storage facility in the world (came online in January ...), meaning those batteries were filling up with excess energy from the sun all afternoon today and are now deploying as we speak to offset a good chunk of the methane gas generation that California still uses overnight." On April 2, the California Independent System Operator (ISO) recommended 26 new transmission projects worth $6.1 billion, with a big number being devoted to offshore wind. In response, Jacobson predicted on April 4 that California will entirely be on renewables and battery storage 24/7 by 2035.

Fusion Experiment Demonstrates Cheaper Stellerator Using Creative Magnet Workaround

Popular Science reports that early last week, researchers at the U.S. Energy Department's Princeton Plasma Physics Laboratory revealed their new "MUSE" stellarator — "a unique fusion reactor that uses off-the-shelf and 3D-printed materials to contain its superheated plasma." The researchers' announcement says the technique suggests "a simple way to build future devices for less cost and allow researchers to test new concepts for future fusion power plants." Stellarators typically rely on complicated electromagnets that have complex shapes and create their magnetic fields through the flow of electricity. Those electromagnets must be built precisely with very little room for error, increasing their cost. However, permanent magnets, like the magnets that hold art to refrigerator doors, do not need electric currents to create their fields. They can also be ordered off the shelf from industrial suppliers and then embedded in a 3D-printed shell around the device's vacuum vessel, which holds the plasma. "MUSE is largely constructed with commercially available parts," said Michael Zarnstorff, a senior research physicist at PPPL. "By working with 3D-printing companies and magnet suppliers, we can shop around and buy the precision we need instead of making it ourselves." The original insight that permanent magnets could be the foundation for a new, more affordable stellarator variety came to Zarnstorff in 2014. "I realized that even if they were situated alongside other magnets, rare-earth permanent magnets could generate and maintain the magnetic fields necessary to confine the plasma so fusion reactions can occur," Zarnstorff said, "and that's the property that makes this technique work." [...] In addition to being an engineering breakthrough, MUSE also exhibits a theoretical property known as quasisymmetry to a higher degree than any other stellarator has before. It is also the first device completed anywhere in the world that was designed specifically to have a type of quasisymmetry known as quasiaxisymmetry. Conceived by physicist Allen Boozer at PPPL in the early 1980s, quasisymmetry means that although the shape of the magnetic field inside the stellarator may not be the same around the physical shape of the stellarator, the magnetic field's strength is uniform around the device, leading to good plasma confinement and higher likelihood that fusion reactions will occur. "In fact, MUSE's quasisymmetry optimization is at least 100 times better than any existing stellarator," Zarnstorff said. "The fact that we were able to design and build this stellarator is a real achievement," said Tony Qian, a graduate student in the Princeton Program in Plasma Physics, which is based at PPPL. Also covered by Gizmodo. Thanks to Slashdot reader christoban for sharing the news.

Could a New Charge Double the Service-life of Li-Ion Batteries?

"An improved charging protocol might help lithium-ion batteries to last much longer," writes Science Daily: The best commercial lithium-ion batteries...have a service life of up to eight years. Batteries are usually charged with a constant current flow. But is this really the most favorable method? A new study by Prof. Philipp Adelhelm's group at HZB and Humboldt-University Berlin answers this question clearly with "no." [In collaboration with teams including the Technical University of Berlin.] Part of the battery tests were carried out at Aalborg University. The batteries were either charged conventionally with constant current (CC) or with a new charging protocol with pulsed current (PC). Post-mortem analyses revealed clear differences after several charging cycles: In the CC samples, the solid electrolyte interface (SEI) at the anode was significantly thicker, which impaired the capacity... PC-charging led to a thinner SEI interface and fewer structural changes in the electrode materials. The study is published in the journal Advanced Energy Materials and analyzes the effect of the charging protocol on the service time of the battery, according to the article. "The frequency of the pulsed current counts..." "Doubling the life of your EV's battery or even your smartphone's battery is no small thing," says Slashdot reader NewtonsLaw...

Calpine's California Battery Plant Is Among World's Largest

Calpine's billion-dolllar Nova Power Bank near Los Angeles will be among the largest in the world when it comes online later this year. According to Reuters, the plant is built on the site of a failed gas-fired power plant and "will be able to power about 680,000 homes for up to four hours when charged." From the report: The 680-megawatt lithium-ion battery bank is big even for California, which boasts about 55% of the nation's power storage capacity, according to data from the U.S. Energy Information Administration. Calpine will bring online 620 MW of the bank in two phases this year starting in the summer and open the remaining 60 MW in 2025. [...] Calpine, best known in the state for its fleet of gas plants, has about 2,000 MW of battery capacity under development. California was a pioneer in mandating that its utilities begin procuring energy storage more than a decade ago. The state is expected to need about 50 gigawatts of battery storage to meet its 2045 goal of getting all of its power from carbon-free sources, up from about 7 GW today.

Mobilité durable : un moteur à hydrogène plein de promesses aux USA

transport routier, automobile, moteur à hydrogène, industrie automobile, poids lourds, mobilité durable, transition énergétique, Argoone, Achates Power, États-Unis, mobilité durable, environnement, empreinte carbone, H2O

L’industrie automobile américaine pourrait bien être sur le point de gravir une nouvelle marche vers la mobilité durable pour les véhicules lourds. Les équipes de l’entreprise Achates Power et du Laboratoire national Argonne sont en train de développer un nouveau type de moteur à hydrogène, en se basant sur un moteur à deux pistons opposés qui a été créé dans les années 1930.

 

 

Un moteur à hydrogène basé sur une innovation centenaire

Les moteurs à pistons opposés, bien que conçus il y a plus de 100 ans, ont retrouvé une nouvelle jeunesse grâce aux efforts conjoints d’Achates Power et du Laboratoire national Argonne. Ce renouveau est marqué par une subvention significative de 133 millions de dollars attribuée par le Département de l’Énergie des États-Unis, visant à repenser cette technologie pour répondre aux défis contemporains de l’industrie automobile. Le projet ambitionne ainsi de transformer ces moteurs, historiquement utilisés dans des applications militaires et maritimes, telles que les porte-avions et les sous-marins, en moteur à hydrogène.

La clé de cette transformation réside dans l’adaptation du moteur à l’hydrogène, un carburant propre qui, en brûlant, rejette exclusivement de l’eau. Par ailleurs, les moteurs à combustion à l’hydrogène offrent des performances égales, voire supérieures, à celles de leurs homologues thermiques et électriques, et ils bénéficient d’une recharge rapide — deux avantages non négligeables de ce type de motorisation par rapport aux batteries électriques.

Vers une mobilité lourde plus propre et durable

Les premiers tests réalisés par Argonne et Achates Power sont très encourageants, et le soutien du gouvernement américain souligne non seulement sa confiance dans le potentiel de cette technologie, mais aussi l’urgence de développer des alternatives propres aux carburants fossiles dans le secteur des transports. L’industrie des poids lourds, en particulier, représente un défi majeur dans la transition énergétique, due à la difficulté d’électrifier ces véhicules à cause de leur besoin en autonomie et en puissance.

L’hydrogène apparaît ainsi comme la clé pour répondre aux défis qui se posent à ce secteur. Et ce d’autant plus du fait que l’on peut produire l’hydrogène pour ces moteurs de manière totalement décarbonée, notamment en électrolysant l’eau, en utilisant de l’énergie éolienne, solaire ou hydraulique. 

 

L’article Mobilité durable : un moteur à hydrogène plein de promesses aux USA est apparu en premier sur L'EnerGeek.

India Hydropower Output Records Steepest Fall In Nearly Four Decades

An anonymous reader quotes a report from Reuters: India's hydroelectricity output fell at the steepest pace in at least 38 years during the year ended March 31, a Reuters analysis of government data showed, as erratic rainfall forced further dependence on coal-fired power amid higher demand. The 16.3% drop in generation from the country's biggest clean energy source coincided with the share of renewables in power generation sliding for the first time since Prime Minister Narendra Modi made commitments to boost solar and wind capacity at the United Nations climate talks at Paris in 2015. Renewables accounted for 11.7% of India's power output in the year that ended in March, down from 11.8% a year earlier, a Reuters analysis of daily load despatch data from the federal grid regulator Grid-India showed. India is the world's third-largest greenhouse gas emitter, and the government often points to lower per-capita emissions compared to developed nations to defend rising coal use. A five-year low in reservoir levels means hydro output will likely remain low during the hottest months of April-June, experts say, potentially boosting dependence on coal during a period of high demand before the monsoon starts in June. [...] Globally, hydropower output fell for only the fourth time since 2000 due to lower rainfall and warmer temperature brought about by the El Nino weather pattern, according to energy think tank Ember. Hydro output in India, the sixth-biggest hydropower producer, fell nearly seven times faster than the global average, Ember data showed.

Bill Gates Says Texas Shows America's Clean-Energy Future

"If you want to see what the cutting edge of next-gen clean energy innovation looks like, it'd be hard to find a place better than Texas," Bill Gates wrote recently on his blog," saying "amazing companies" are breaking ground across the state. "Each one represents a huge boon for the local economy, America's energy security, and the fight against climate change." The world is undergoing an energy transition right now, fueled by the development and deployment of new clean energy technologies. The pace of innovation at the heart of this transition is happening faster than many people (including me!) dared hope. The progress makes me optimistic about the future — and excited about the role that American communities will play, especially in places like Texas. Breakthrough Energy and I have invested more than $130 million into Texas-based entrepreneurs, institutions, and projects. It's a big bet, but it's one I'm confident in. Why? Because of the people. Nearly half a million Texans work in the oil and gas industry, and their skills are directly transferrable to next-generation industries. This workforce will help form the backbone of the world's new clean energy economy, and it will cement Texas's energy leadership for generations to come. Many of the companies I'm seeing on this trip already employ or plan to employ oil and gas workers. One of those companies is Infinium, which is working on next-generation clean fuels for trucks, ships, and even planes. I'm visiting their first demonstration plant in Corpus Christi, where they're turning waste CO2 and renewable energy into electrofuels — or eFuels — for trucks. They've already signed a deal with Amazon, and sometime soon, if you live in the area, you might get a delivery supported by Infinium eDiesel. The key to Infinium's approach is that their fuels can be dropped into existing engines... I'm especially excited about the work they're doing on sustainable aviation fuel, or SAF — which could reduce emissions from air travel by as much as 90 percent, according to company estimates. Infinium is in the process of converting an old gas-to-liquid plant in West Texas into a new facility that will increase the company's capacity for producing eFuels ten-fold. Breakthrough Energy's Catalyst program has invested in this first-of-its-kind plant, and I can't wait to see it when it's done. Another company I'll see is Mars Materials. They're a Breakthrough Energy Fellows project working on a different way to reuse CO2. The company is developing a clever technique for turning captured carbon into one of the key components in carbon fiber, an ultra-light, ultra-strong material that is used in everything from clothing to car frames... The Mars Materials team relocated from California to Texas in part because of the skilled oil and gas talent that they could access in the state, and they aren't the first Breakthrough Energy company to do that. I'm going to check out their lab, where their scientists are hard at work optimizing the conversion process. Both companies assume abundant CO2, Gates writes, but "fortunately for them, Texas is also in the process of becoming a capital for direct air capture... A recent study found that Texas has the greatest DAC deployment potential in the country and could create as many as 400,000 jobs by 2050." Already a direct air capture "hub" in Kingsville, Texas is expected to create 2,500 jobs over the next five years, while Houston has been selected as the site for one of America's seven Regional Clean Hydrogen Hubs.

Are State Governments Slowing the Build-Out of America's EV Charging Stations?

In November of 2021 America passed a "Bipartisan Infrastructure Law" which included $7.5 billion for up to 20,000 EV charging spots, or around 5,000 stations, notes the Washington Post (citing an analysis from the EV policy analyst group Atlas Public Policy). And new stations are now already open in Hawaii, New York, Ohio and Pennsylvania, "and under construction in four other states. Twelve additional states have awarded contracts for constructing the charging stations." A White House spokesperson said America should reach its goal of 500,000 charging stations by 2026. So why is it that right now — more than two years after the bill's passage — why does the Federal Highway System say the program has so far only delivered seven open charging stations with a total of 38 charging spots? Nick Nigro, founder of Atlas Public Policy, said that some of the delays are to be expected. "State transportation agencies are the recipients of the money," he said. "Nearly all of them had no experience deploying electric vehicle charging stations before this law was enacted." Nigro says that the process — states have to submit plans to the Biden administration for approval, solicit bids on the work, and then award funds — has taken much of the first two years since the funding was approved. "I expect it to go much faster in 2024," he added. "We are building a national EV charging network from scratch, and we want to get it right," a spokesperson for the Federal Highway Administration said in an email. "After developing program guidance and partnering with states to guide implementation plans, we are hitting our stride as states move quickly to bring National Electric Vehicle Infrastructure stations online...." Part of the slow rollout is that the new chargers are expected to be held to much higher standards than previous generations of fast chargers. The United States currently has close to 10,000 "fast" charging stations in the country, of which over 2,000 are Tesla Superchargers, according to the Department of Energy. Tesla Superchargers — some of which have been opened to drivers of other vehicles — are the most reliable fast-charging systems in the country. But many non-Tesla fast chargers have a reputation for poor performance and sketchy reliability. EV advocates have criticized Electrify America, the company created by Volkswagen after the company's "Dieselgate" emissions scandal, for spending hundreds of millions of dollars on chargers that don't work well. The company has said they are working to improve reliability. The data analytics company J.D. Power has estimated that only 80 percent of all charging attempts in the country are successful. Biden administration guidance requires the new publicly funded chargers to be operational 97% of the time, provide 150kW of power at each charger, and be no more than one mile from the interstate, among many other requirements.EV policy experts say those requirements are critical to building a good nationwide charging program — but also slow down the build-out of the chargers. "This funding comes with dozens of rules and requirements," Laska said. "That is the nature of what we're trying to accomplish.... "States are just not operating with the same urgency that some of the rest of us are." The article notes that private companies are also building charging stations — but the publicly-funded spots would increase America's car-charging capacity by around 50 percent, "a crucial step to alleviating 'range anxiety' and helping Americans shift into battery electric cars. "States just have to build them first."
