Energy Startup Arbor Notches $41M Deals Amid Trump Reversals

Arbor, a startup that promises both CO2 removal and clean baseload power, just announced $41 million in offtake deals as it courts hyperscalers' growing energy needs.

Why it matters: The contracts for 116,000 tons of CO2 removal between 2028 and 2030, for buyers working through the Frontier consortium, comprise Arbor's biggest deal yet.

• It's one of the "anchor agreements" that will help the 3-year-old startup finance and build its first commercial-scale plant near Lake Charles, Louisiana, CEO Brad Hartwig tells me.
  

Driving the news: Buyers include Stripe, Google, Shopify, McKinsey, Autodesk, H&M and various others.

• The new deal follows a much smaller agreement with Microsoft last year.
  

How it works: Arbor is a bioenergy with carbon capture (BECCS) startup, using waste biomass that will initially come from forest management.

• But it's an evolution of BECCS, with 99% capture and high efficiency, a blog post states.

• Its process first gasifies biomass, then burns that gas in a special furnace with pure oxygen ("oxy-combustion"), producing water but also "supercritical" CO2 that drives a turbine.

• This simplifies and reduces CO2 capture costs, and the water can be used for irrigation or data center cooling, Arbor and Frontier said.

Reality check: First-of-a-kind hardware systems often don't survive the journey to commercial deployment or scale.

• But Hartwig sees Arbor's system among the energy sources that stand to benefit from the AI boom.

• "Demand for carbon-free energy is just accelerating at rates that are completely unprecedented, and we have a pretty unique technology stack that can deliver 24/7, carbon-free energy that is cheap and firm," he tells Axios.

What we're watching: "We've gotten a lot of interest from a whole host of folks, from hyperscalers to regulated utilities looking to develop projects for matching supply with load for data centers," Hartwig said.

The intrigue: Asked whether Trump 2.0's reversal of climate policies creates headwinds, he argued the opposite, citing "real interest in baseload power that can add to grid resilience."

• He also said behind-the-meter deployments are possible, avoiding the need for transmission or waiting in interconnection queues.
  

State of play: "Its compact design features an 18 MW turbine about the size of a car engine, allowing for efficient scaling and cost reductions," the announcement states.

• Its modular system and oxy-combustion tech don't produce exhaust or pollution, avoiding the cost of adding separate CO2 capture units.

• Scaling the technology provides an eventual pathway toward getting under $100/ton of removal, the post states.

• The tech also works using natural gas, which would provide power with CO2 capture, but it's not removal without the biomass.

The bottom line: "The demand from AI is a big part of helping pull technologies like ours across the development valleys of death, to get a new technology into the world," Hartwig said.
