WASHINGTON DC – The U.S. Department of Energy (DOE) today announced up to $ 45 million to support the development of technologies that can turn buildings into net carbon storage structures. With building materials that store carbon often being scarce, expensive, and geographically limited, DOE is pioneering technologies that overcome these barriers to reduce or eliminate the emissions associated with their production. It will also increase the total amount of carbon stored in buildings to make them net carbon negative and contribute to President Biden’s goal of achieving net zero emissions by 2050.

“Building materials and construction techniques show great promise as carbon sinks,” said Energy Secretary Jennifer M. Granholm. “As it has done in so many other sectors of our economy, DOE’s ARPA-E will once again try to be a game-changer.”

Greenhouse gas (GHG) emissions associated with the manufacturing and construction of materials, renovation and disposal of end-of-life buildings represent approximately 10% of total annual emissions in the United States. These intrinsic emissions are concentrated at the start of a building’s lifespan, making them essential to address given the urgency of addressing national energy and environmental challenges. More importantly, these emissions represent an increasing percentage of total building lifecycle emissions as operational emissions decrease due to factors such as improved efficiency and decarbonization of the power grid.

The DOE-Energy Advanced Research Projects Agency (ARPA-E) will provide up to $ 41 million in funding to exploit emissions in structures taking into account atmospheric inputs (HESTIA), for the development and demonstration of construction materials and whole building designs that are net carbon negative by removing carbon dioxide from the atmosphere during the production process and storing carbon in the finished product. The DOE is also funding $ 4 million to develop building lifecycle analysis tools and frameworks associated with carbon reduction and storage in building construction.

The successful HESTIA proposals will reduce the environmental footprint of production and domestic resource use, as well as the use of construction materials and designs that remove carbon dioxide from the atmosphere and store carbon in the product. finished.
