"Two years ago, former SpaceX engineers used rocket tech to develop a power plant capable of removing carbon dioxide from the atmosphere, with a small asterisk. To draw down CO 2, it burned plant waste, making it a sort of "vegetarian rocket engine" for the grid. This week, Arbor Energy said it had raised a $55 million Series A led by Lowercarbon Capital and Voyager Ventures on the heels of a partial pivot."
"Arbor still plans to capture CO 2 from the power plant, which uses oxy-combustion, which transforms hydrocarbons into syngas and then burns it in the presence of pure oxygen. The result is CO 2 that doesn't need much preparation for sequestration. Because of tax credits, storing the CO 2 will be cheaper than dumping the pollutant into the atmosphere, Arbor spokesperson Patrick Mahoney told TechCrunch."
Former SpaceX engineers developed a power plant that used oxy-combustion and biomass to remove carbon dioxide from the atmosphere. The plant originally burned plant waste to produce concentrated CO 2 suitable for sequestration. Arbor Energy raised $55 million in Series A funding and pivoted to allow burning natural gas in addition to biomass to meet rising electricity demand from data centers. The design converts hydrocarbons into syngas and burns them in pure oxygen, producing CO 2 that requires minimal preparation for storage. Tax credits make storing captured CO 2 cheaper than releasing it. Methane leakage risks in the natural gas supply chain could offset climate benefits.
