The U.S. Department of Energy announced $39 million in awards for 18 projects that are developing technologies to transform buildings into net carbon storage structures.
Several of these awards consist of alternative concrete and cement materials, as part of the DOE push to improve energy efficiency and reduce greenhouse gas emissions, said Marina Sofos, program director at the DOE’s Advanced Research Projects Agency-Energy.
The direct CO2 intensity of cement production increased 1.8% per year during 2015 to 2020, according to an International Energy Agency report, while a 3% yearly decline to 2030 is needed to get on track with its Net Zero Emissions by 2050 goal to mitigate the worst effects of climate change.
