Frontier is helping Arbor build a “vegetarian rocket engine” to power data centers

Arbor, supported by a $41 million deal with Frontier, is developing its first commercial-scale power plant in southern Louisiana that uses waste biomass to generate electricity for data centers while capturing and sequestering the resulting CO2 underground. This technology, called BiCRS (biomass carbon removal and storage), produces carbon-free base load energy and achieves net carbon removals by burning biomass and capturing 99% of the CO2 emissions. The process involves converting biomass into syngas using a proprietary gasifier that employs supercritical CO2, then combusting the syngas with pure oxygen to generate electricity via turbomachinery, while diverting most CO2 for permanent storage. The approach leverages sustainable biomass sources, with Frontier emphasizing careful vetting to ensure biomass use does not disrupt natural cycles or soil health. Although biomass availability varies, estimates suggest 1 to 5 gigatons of waste biomass could be sustainably utilized annually, offering significant potential for BiCRS and related bioenergy with
