About
Arbor Energy is developing biomass-fired rocket turbines that combust waste biomass at extremely high temperatures, producing supercritical CO2 as a working fluid that drives a turbine — making it a carbon-negative power source that captures CO2 as a byproduct rather than releasing it. The company raised $55 million in Series A financing plus $41 million from the Frontier carbon removal marketplace, and received a $1 billion+ order from GridMarket for up to 5 gigawatts of turbine capacity in March 2026 — one of the largest commercial orders in the energy startup category.
Valero Energy (VLO) reported ~$140B revenue in FY2024. Largest independent petroleum refiner in the world with 15 refineries and 3.2M barrels/day capacity. HQ: San Antonio, TX.
