Brad Hartwig is CEO and founder of Arbor, and today’s topic is BiCRS. No, not the people in black leather jackets cruising down the highway, but rather the acronym for the process of biomass carbon removal and storage, BiCRS. Arbor is developing a process that transforms organic waste from forest thinning to prevent wildfires. The company’s process converts the carbon in the waste into stored CO2, while also producing clean energy and freshwater as byproducts. Specifically, Arbor's process runs wood waste through a light thermal treatment known as torrefaction, which is somewhat akin to roasting coffee beans. They take this torrefied biomass and gasify it into syngas and then combust it with pure oxygen to produce clean water and high purity CO2, which they then run through a highly dense turbine to create carbon negative electricity while injecting the CO2 into permanent sequestration.

The plants that they will build to operate this process end to end will be significantly smaller than existing biomass energy facilities. And Arbor has an audacious vision to own and operate these carbon capture plants in a distributed nature near carbon injection wells and sequestration facilities, selling the excess power that they generate back to the grid or to the facilities themselves.

We start the conversation going into Brad's inspiring background, which includes time as a rocket engineer at SpaceX and nearly a decade on the USA National Swim Team, while also volunteering for Marin County Search and Rescue and the California Air National Guard. We cover how he surveyed the entire carbon dioxide removal space before landing on the idea for BiCRS and how his aerospace background seemed particularly well suited for Arbor's specific approach.
