New ‘SAF’ Just Dropped

A natural gas refinery is being converted into a plant for jet fuel made from carbon dioxide and green hydrogen.

American Airlines will purchase sustainable aviation fuel from a first-of-its-kind facility under development in Texas called Project Roadrunner. Infinium, the company behind the project, will be converting a former natural gas refinery into a commercial “eFuels” plant where it will make jet fuel and diesel from carbon dioxide and green hydrogen. The company announced the offtake agreement on Wednesday along with a $75 million equity agreement with Breakthrough Energy Catalyst, a subsidiary of a climate tech firm backed by Bill Gates that focuses on first-of-a-kind projects. Infinium specified that it would use “waste CO2” for the process, although it did not say where the carbon would be sourced from.

Most so-called sustainable aviation fuels in use today are made from waste cooking oils and agricultural residues, but experts are skeptical they’re truly scalable. In theory, fuel made from carbon dioxide captured from the atmosphere and green hydrogen could be carbon neutral, though capturing the carbon, and producing green hydrogen, requires a lot of energy.

    One Reason Trump Wants Greenland: Critical Minerals

    A top aide to incoming President Donald Trump is claiming the president-elect wants the U.S. to acquire Greenland to acquire more rare minerals.

    “This is about critical minerals. This is about natural resources,” Trump’s soon-to-be national security advisor Michael Waltz told Fox News host Jesse Watters Thursday night, adding: “You can call it Monroe Doctrine 2.0, but it’s all part of the America First agenda.”

    An Insurance Startup Faces a Major Test in Los Angeles

    Kettle offers parametric insurance and says that it can cover just about any home — as long as the owner can afford the premium.

    Los Angeles is on fire, and it’s possible that much of the city could burn to the ground. This would be a disaster for California’s already wobbly home insurance market and the residents who rely on it. Kettle Insurance, a fintech startup focused on wildfire insurance for Californians, thinks that it can offer a better solution.

    The company, founded in 2020, has thousands of customers across California, and L.A. County is its largest market. These huge fires will, in some sense, “be a good test, not just for the industry, but for the Kettle model,” Brian Espie, the company’s chief underwriting officer, told me. What it’s offering is known as “parametric” insurance and reinsurance (essentially insurance for the insurers themselves.) While traditional insurance claims can take years to fully resolve — as some victims of the devastating 2018 Camp Fire know all too well — Kettle gives policyholders 60 days to submit a notice of loss, after which the company has 15 days to validate the claim and issue payment. There is no deductible.

    What the L.A. Fires Are Doing to the City’s Air

    The Santa Ana winds are carrying some of the smoke out to sea.

    Wildfires have been raging across Los Angeles County since Tuesday morning, but only in the past 24 hours or so has the city’s air quality begun to suffer.

    That’s because of the classic path of the Santa Ana winds, Alistair Hayden, a public health professor at Cornell who studies how wildfire smoke affects human health, told me. “Yesterday, it looked like the plumes [from the Palisades fire] were all blowing out to sea, which I think makes sense with the Santa Ana wind patterns blowing to the southwest,” Hayden said.
