The U.S. Treasury Department will open applications on May 31 for $4 billion in new tax credits for advanced energy manufacturing and decarbonization projects, with $1.6 billion needed for communities impacted by the closure of coal mines or coal-fired power plants . To qualify for the first round, applicants must submit a "concept paper" to the Department of Energy by July 31. Treasury guidance for the program gave several examples of projects that might be eligible, including projects that capture or store carbon dioxide, produce hydrogen using zero- or low-emission energy sources, produce renewable biofuels and pure electric vehicles, and those vehicles and key materials for charging infrastructure. Additional low-income credits for wind and solar projects in low-income and disadvantaged "environmental justice" communities are limited to 1.8 gigawatts of gross generation per year, limited to 5 megawatts per project. The Ministry of Finance will allocate 200 MW of capacity for facilities located on Indian land and 200 MW for federally subsidized residential buildings.
