The US Department of Energy (DOE) has announced $39 million in awards for 18 projects seeking to develop technologies that can transform buildings into net carbon storage structures.

The Harnessing Emissions into Structures Taking Inputs from the Atmosphere (HESTIA) programme will be led by the DOE’s Advanced Research Projects Agency-Energy (ARPA-E).

Selectees will prioritise overcoming barriers associated with carbon-storing buildings, including scarce, expensive and geographically limited building materials.

“There’s huge, untapped potential in reimagining building materials and construction techniques as carbon sinks that support a cleaner atmosphere and advance President Biden’s national climate goals,” stated US secretary of energy Jennifer M. Granholm. “This is a unique opportunity for researchers to advance clean energy materials to tackle one of the hardest to decarbonise sectors that is responsible for roughly 10% of total annual emissions in the United States.”

According to the DOE, greenhouse gas (GHG) emissions associated with material manufacturing and construction, renovation and disposal of buildings at the end of their service life are concentrated at the start of a building’s lifetime.  

This is essential to address given the urgency of meeting national energy and environmental challenges.

In addition to the HESTIA program, ARPA-E recently announced $5 million in funding through the HESTIA Exploratory Topic to two universities working to develop the necessary life cycle assessment tools and frameworks associated with transforming buildings into net carbon storage structures.

This announcement from the DOE is the latest from the North American department to mirror US President Biden’s plan to reach zero emissions by 2050.

Other announcements from earlier in the year include the i2X partnership to connect more clean energy to the national grid, $12 million to enhance the country’s cybersecurity and the ‘Building a Better Grid’ initiative, which aims to speed up the modernisation of the country’s energy transmission infrastructure.
