"Unlike many of the climate-related projects Exxon is undertaking, this plant is highly experimental. Exxon has previously said that its low-carbon businesses like biofuels and lithium-mining need to make double-digit returns. Direct air capture, by comparison, is more of a space-age science experiment for now—one that may pay off or fade away. The company isn’t disclosing how much it’s spending on the project."

"Note that this is not a finger-pointing exercise where rich countries tell poorer ones not to pollute. We’re mostly talking about local air pollution. The negative impacts of pollution are felt by domestic populations. It’s about how we ensure that the poorest countries can gain access to energy, alleviate poverty, and develop while limiting the number of people who die prematurely from air pollution in the process."

"LanzaTech’s approach is to take waste carbon emissions from an industrial site and inject them into a bioreactor with the bacteria. From there, the bacteria digest the gas to produce ethanol and a protein coproduct."

"Google and Microsoft have also teamed up with Nucor, a giant American operator of steel mini-mills, which consume lots of electricity. In March the trio announced that they will aggregate demand and jointly offer contracts to clean-energy projects, both early-stage commercial ones and entirely novel 'first-of-a-kind' ventures. The idea is to guarantee custom for developers of promising technologies like long-duration energy storage, clean hydrogen, next-generation geothermal and nuclear energy."

"The company can reduce its own waste as well. If it determines that a user has no preference between broccoli and Brussels sprouts, and the company happens to have more broccoli in its warehouse, that’s what they’ll recommend."

"The startup analyzed its climate impacts and found its product generates 80% less carbon dioxide compared to traditional plastic at commercial scale. The manufacturing process can use existing pulp mill machinery to make rolls of plastic."
