Frontier, supported by Stripe, Google, and Meta, has partnered with startup Arbor Energy to remove 116,000 tons of carbon dioxide by the end of the decade. This agreement provides Arbor with $41 million to construct its first commercial-scale power plant in southern Louisiana, which will run on waste biomass to produce electricity for a data center while also sequestering CO2 for underground storage. The facility aims to generate 5 to 10 megawatts of electricity. Arbor has developed a unique gasifier, as off-the-shelf options were inadequate. This gasifier uses supercritical CO2 from the plant itself to process biomass, producing syngas, which is then burned to generate electricity. Most of the produced CO2 will be sent to a pipeline for permanent storage, with some redirected back to the gasifier. Arbor co-founder and CEO Brad Hartwig has previously, aptly described the power plant as a “vegetarian rocket engine.” The entire system captures 99% of the CO2 released by the combustion, far higher than competing methods. And because it’s burning biomass, the process removes carbon from the atmosphere. Frontier estimates there is between 1 to 5 gigatons of waste biomass available every year. Even if only 1 gigaton meets those standards, there’s still a lot of potential for BiCRS and its close cousin, bioenergy with carbon capture and storage (BECCS), to make a significant dent in future energy needs. For Frontier, Arbor will only burn biomass, ensuring the power plant will remove carbon as required by the deal.
