Process Engineer at Arborenergy

At Arbor, we are pioneering a scalable and affordable method for Biomass Carbon Removal and Storage. By utilizing advanced rocket engine technology, we convert forestry waste into clean electricity, water, and high-purity carbon dioxide. Our process relies on compact gasification, oxy-combustion with a supercritical CO2 cycle, and high-pressure turbo-expansion to ensure carbon is captured and sequestered permanently. Since our founding two years ago, we have secured over $30 million in funding from leading deeptech investors, assembled an elite team of scientists and engineers, and pre-sold our first 2,000 tons of carbon removal. We are currently designing our inaugural plant to demonstrate our carbon-negative energy technology, and we invite you to join us in our mission to foster planetary partnership.
