The U.S. Department of Energy (DOE) today announced $39 million in awards for 18 projects seeking to develop technologies that can transform buildings into net carbon storage structures. Led by DOE’s Advanced Research Projects Agency-Energy (ARPA-E), selectees for the Harnessing Emissions into Structures Taking Inputs from the Atmosphere (HESTIA) program will prioritize overcoming barriers associated with carbon-storing buildings, including scarce, expensive and geographically limited building materials. Decarbonization goals for the HESTIA program mirror President Biden’s plan to reach zero emissions by 2050 and aim to increase the total amount of carbon stored in buildings to create carbon sinks, which absorb more carbon from the atmosphere than released during the construction process.
