WASHINGTON (AP) — The Biden administration has selected clean-energy projects from Pennsylvania to California for a $7 billion program to kickstart development and production of hydrogen fuel. That’s a key component of President Joe Biden’s agenda to slow climate change. The Democratic president wants to establish seven regional hydrogen hubs to help replace fossil fuels such as coal and oil with cleaner-burning hydrogen as an energy source for vehicles, manufacturing and generating electricity. Biden is expected to make the official announcement Friday during an economic-themed visit to Philadelphia. The White House calls hydrogen essential to achieving Biden’s “vision of a strong, clean energy economy” and net-zero greenhouse gas emissions in the U.S. by 2050.
