AM Briefing: 'Bigger Than the Hoover Dam'

On a major clean energy infrastructure project, mapping ocean activity, and liquid hot magma

Current conditions: The western U.S. is in the midst of a severe “snow drought” • The Great Lakes began 2024 with their smallest amount of ice cover in 50 years • Finland’s Enontekiö airport recorded the country’s coldest January temperature since 2006: -44 degrees Fahrenheit.

THE TOP FIVE

1. Offshore wind sees a turbulent start to 2024

“The rollercoaster that is the U.S. offshore wind industry is already racing in 2024,” says Canary Media’s Maria Gallucci. Indeed, after missing an end-of-year deadline to start sending energy to the U.S. grid, the nation’s first large-scale offshore wind farm came online at 11:52 p.m. on Tuesday, delivering five megawatts of power to the New England grid. The Vineyard Wind 1 project, located near Martha’s Vineyard, will eventually consist of 62 turbines capable of powering 400,000 homes in Massachusetts.

“The arrival of Vineyard Wind is a welcome tonic to a nascent offshore wind industry that has struggled in the US in recent months,” writes Oliver Milman at The Guardian. But on Wednesday, BP and Equinor abandoned a contract to sell offshore wind energy to the state of New York, citing the familiar headwinds of rising costs, interest rates, and supply chain problems. Last October the companies tried to negotiate with the state for higher rates for selling renewable energy credits. Their request was turned down, only for the state to open the floor to new project proposals, including from BP and Equinor. “The agreement is the latest evidence of the malaise engulfing the fledgling offshore US wind industry,” writes Myles McCormick at the Financial Times, “but also illustrates the willingness of state authorities to provide flexibility to prevent projects from being abandoned.”

2. Construction goes ahead on SunZia clean energy transmission line

Some important renewable energy news went under the radar this week: Pattern Energy’s SunZia Transmission line secured $11 billion in financing, which means construction can continue on the “largest clean energy infrastructure project in U.S. history.” The 550-mile high-voltage direct current (HVDC) transmission line will run between central New Mexico and south-central Arizona, delivering power to western states from the SunZia Wind facility being built in New Mexico. “The size and scale of both the SunZia project and this multifaceted financing show that the renewable energy space can secure attractive capital at levels previously only seen in traditional generation,” says Daniel Elkort, executive vice president at Pattern Energy.

Upgrading transmission systems will be key to meeting the Biden administration’s goal of eliminating carbon emissions from the power sector by 2035: By one estimate, transmission systems will need to expand by 60% by 2030. The SunZia Transmission line will be able to move 3,000 megawatts of wind power to 3 million people and has been called “bigger than the Hoover Dam.” But its progress has been rocky: Indigenous groups have expressed concerns about the line’s impact on religious and cultural sites, and environmentalists worried it could harm wildlife habitat.

3. New maps show hidden extent of industrial activity at sea

Incredible new maps published in the journal Nature expose the great extent to which human activity has pervaded the world’s oceans. For the project, researchers led by Google-backed nonprofit Global Fishing Watch used artificial intelligence to analyze huge amounts of offshore data from satellite imagery. They found that many industrial vessels aren’t publicly tracked, exposing a potential blindspot for conservation efforts. The data also showed that offshore wind turbines now outnumber oil structures:

4. GOP climate advocate John Curtis launches Senate bid

Utah Rep. John Curtis announced this week he is running for the Senate seat left vacant by retiring Sen. Mitt Romney. The primary field is likely to be crowded, but Curtis’s entry is interesting because he is “one of the GOP’s leading voices on fighting climate change,” says E&E News. He launched and chairs the Conservative Climate Caucus, has supported some of the Biden administration’s policies on solar, and attended COP28 to push for permitting reform. But it will be interesting to see whether climate change features prominently in his campaign: Curtis didn’t mention environmental issues in his first campaign video but pledged to “work to make America not just energy independent, but energy dominant.”

5. Researchers hope volcanic magma could provide ‘quantum leap’ in geothermal energy

Researchers in Iceland have plans to drill into a magma chamber beneath a volcano in an attempt to better understand the hot molten rock and eventually even “make a quantum leap in geothermal energy production,” reports New Scientist. The Krafla Magma Testbed (KMT) project will start drilling in 2026, focusing on a volcano called Krafla in north-east Iceland. The researchers hope to develop near-magma geothermal energy technology that would allow wells to trap hot, pressurized water to drive turbines and produce cheap, clean electricity. “There are endless opportunities,” says Hjalti Páll Ingólfsson at the Geothermal Research Cluster (GEORG) in Reykjavík. “The only thing we need to do is to learn how to tame this monster.”

THE KICKER

A company called Moolec Science has been inserting pig genes into soy plants to produce beans that are pink and taste meaty.

It’s the Artificial Intelligence Muddle Now

SoftBank’s error and Nvidia’s scandal suggest data centers may have already peaked as an economic and energy trend.

Covering energy and climate change sometimes means seeing certain stories in a different light than others. And a particularly vivid hue illuminated The Wall Street Journal’s report today that the Japanese conglomerate SoftBank Group is taking a $3.7 billion loss on several gigawatts’ worth of natural gas turbines.

Running a Smart Home Energy System Takes a Lot of Software

Lunar Energy’s latest AI-powered system aims to integrate EVs into the automated demand response mix.

In theory, it’s straightforward to assemble the smart energy home: Solar panels, home backup batteries, and electric vehicles, plus smart thermostats, heat pumps, and water heaters — all the individual pieces can be had for the homeowner who can afford the up-front cost. The challenge is getting all those pieces to talk to one another.

Bay Area-based Lunar Energy is one of the tech firms that’s been trying to crack this problem. Today, it announced an upgraded version of its artificial intelligence-powered home energy control system, which not only integrates all those separate systems but also responds tactically to energy markets. CEO Kunal Girotra told me Lunar AI saves its users money by monitoring their home 24/7 and making decisions to charge, not to charge, or discharge so that they save the most money.

Exclusive: Coreshell Raises $30 Million to Replace Chinese Graphite With American Silicon

The fundraise comes on the heels of a $50 million grant from the Department of Energy.

Almost all lithium-ion batteries on the market rely on graphite for their anodes, more than 90% of which is processed in China. That concentration has created a chokepoint in the Pentagon’s supply chain as the military increasingly turns to batteries to help its transportation network operate more quietly and reduce reliance on complex refueling logistics.

So when Congress passed the latest National Defense Authorization Act at the end of 2025, barring Chinese-linked battery materials from military use starting in 2028, Coreshell saw an opening. While the California-based silicon-anode battery startup had previously focused on automakers as its beachhead customers, it’s now shipping its first battery cells to the military for use on Navy ships and Army ground vehicles. On Wednesday, Coreshell announced a $30 million Series B to scale up manufacturing operations to meet the needs of this growing customer base.
