2 Climate Removal Deals, 1 Final Tax Credit Rule

On ocean-based CO2, Grizzly 399, and the 45X tax credit.

Current conditions: Tropical Storm Trami brought widespread flooding to the Philippines, killing at least 24 people • The Southwestern U.S. is experiencing a heatwave, with temperatures as high as 25 degrees Fahrenheit above normal • The three NASA astronauts stuck at the International Space Station due to inclement weather are finally on their way home.

THE TOP FIVE

1. Climeworks 🤝 Morgan Stanley

The Swiss direct air capture company Climeworks has found a new, deep-pocketed partner in Morgan Stanley. The financial services company will pay an undisclosed amount to Climeworks to suck 40,000 tons of CO2 from the air and store the greenhouse gas underground on its behalf. This is the second largest deal Climeworks has secured to date, following an 80,000-ton sale to Boston Consulting Group, and the company says the purchase will help accelerate progress on its first project in the United States, a direct air capture hub in Louisiana called Project Cypress.

2. Microsoft goes big on ocean CDR

Meanwhile, Microsoft is rounding out its already extensive carbon removal portfolio with its first major investment in ocean-based technology. The tech giant agreed to buy up to 350,000 tons of CO2 removal from a startup called Ebb Carbon over the next 10 years, slightly more than its deal with the direct air capture company Heirloom.

Ebb uses electricity to separate seawater into acidic and basic streams, then returns the basic stream back to the ocean, where it reacts with carbon in the water and promotes faster CO2 absorption from the air. The company must achieve and verify an initial 1,300 tons of CO2 removal before Microsoft commits to buying the remainder. The company has a small pilot project up and running at the Pacific Northwest National Laboratory in Washington, and is working with federal scientists and the University of Washington to measure and model the results.

3. The IRA’s X-Factor is in full effect

The Treasury Department issued final rules this morning for the Advanced Manufacturing Production Tax Credit, also known as 45X. The program is the backbone of the Inflation Reduction Act, offering incentives for domestic manufacturing of the components of solar panels, wind turbines, and batteries, subsidizing every step of the supply chain for these technologies. During a call with reporters on Wednesday, Deputy Secretary of the Treasury Wally Adeyemo said the tax credit has already driven more than $126 billion in private sector clean energy manufacturing investments.

The biggest change introduced in the final rule that the administration highlighted was allowing critical mineral extraction — separately and in addition to mineral processing — to qualify for a 10% tax credit. “The U.S. has major deposits of critical minerals like lithium and palladium. Extracting and processing them here in America, as opposed to relying on China, Russia, and other countries with weak worker and environmental protection, is an economic and national security priority for us,” Adeyemo said.

  • 4. An update on Vineyard Wind

    Engineers at GE Vernova, the manufacturer of the Vineyard Wind offshore turbine blade that crashed into the ocean this summer, have been poring over ultrasound images of its other blades and conducting physical inspections with drones to figure out whether the fiasco was a one-off or a more widespread issue. During an earnings call on Wednesday, CEO Scott Strazik revealed that the company did, in fact, find a similar “manufacturing deviation” in “a very small proportion, low single-digit proportion” of the blades. The company now intends to “remove some blades from the Vineyard Wind farm while strengthening other blades as needed,” according to an update from Vineyard Wind.

    5. Another (potential) nuclear revival

    The 600 megawatt Duane Arnold Energy Center just outside Cedar Rapids, Iowa could be the next shuttered nuclear plant to come back from the dead. The plant’s owner, NextEra, is evaluating a restart, CEO John Ketchum told investors on an earnings call yesterday. “It goes without saying, there’s very strong interest from customers, data-center customers in particular, in that site,” Ketchum said. “We’re in a period of substantial power demand.”

    THE KICKER

    Grizzly 399, the world-renowned, 400-pound bear that roamed Grand Teton National Park for nearly 30 years, died tragically on Tuesday after being hit by a Subaru on the highway. She leaves behind more than a dozen offspring, including a cub born just last year that fans have nicknamed “Spirit.”

    Zanskar Raises $115 Million to Propel Geothermal Discoveries

    One of the buzziest climate tech companies in our Insiders Survey is pushing past the “missing middle.”

    One of the buzziest climate tech companies of the past year is proving that a mature, hitherto moribund technology — conventional geothermal — still has untapped potential. After a breakthrough year of major discoveries, Zanskar has raised a $115 million Series C round to propel what’s set to be an investment-heavy 2026, as the startup plans to break ground on multiple geothermal power plants in the Western U.S.

    “With this funding, we have a six power plant execution plan ahead of us in the next three, four years,” Diego D’Sola, Zanskar’s head of finance, told me. This, he estimates, will generate over $100 million of revenue by the end of the decade, and “unlock a multi-gigawatt pipeline behind that.”

    1. New Jersey’s new governor freezes electricity prices during inauguration speech

    Mikie Sherrill wasted no time in fulfilling the key pledge that animated her campaign for governor of New Jersey. At her inauguration Tuesday, the Democrat signed a series of executive orders aimed at constraining electricity bills and expanding energy production in the state. One order authorized state utility regulators to freeze rate hikes. Another directed the New Jersey Board of Public Utilities “to open solicitations for new solar and storage power generation, to modernize gas and nuclear generation so we can lower utility costs over the long term.” Now, as Heatmap’s Matthew Zeitlin put it, “all that’s left is the follow-through,” which could prove “trickier than it sounds” due to “strict deadlines to claim tax credits for renewable energy development looming.”

    Why America’s Climate Emissions Surged in 2025

    Rob talks through Rhodium Groups’s latest emissions report with climate and energy director Ben King.

    America’s estimated greenhouse gas emissions rose by 2.4% last year — which is a big deal since they had been steady or falling in 2023 and 2024. More ominously, U.S. emissions grew faster than our gross domestic product last year, suggesting that the economy got less efficient from a climate pollution perspective.

    Is this Trump’s fault? The AI boom’s? Or was it a weird fluke? In this week’s Shift Key episode, Rob talks to Ben King, a climate and energy director at the Rhodium Group, about why U.S. emissions grew and what it says about the underlying structure of the American economy. They talk about the power grid, the natural gas system, and whether industry is going to overtake other emissions drivers as once thought.
