The U.S. Department of Energy's Fossil Energy Research and Development (CFDA 81.089) program awarded a $1,250,017 Cooperative Agreement to Arizona State University (ASU) to demonstrate the sequestration of anthropogenic carbon as a durable and long-lasting bio-asphalt material.
The project aims to combine a novel algae cultivation technology with highly productive extremophile algae to remove carbon dioxide (CO2) from the environment. The algal biomass will be processed via hydrothermal liquefaction to produce the bio-asphalt material, which will then be characterized and evaluated for longevity of carbon storage. Technoeconomic and life-cycle analyses will be conducted to assess the economic and environmental impact of the proposed processes. The award has an end date of August 25, 2025.
