Specifically, they're now vending H2 in Aiken County, South Carolina. The hydrogen is coming from the Economic Development Partnership and the Center for Hydrogen Research with a newly-opened hydrogen fueling station at Sage Mill Industrial Park.
Currently the hydrogen is imported to South Carolina. But from elsewhere in the U.S. It currently costs about $7 per kilo(gram). The fuelling station got much fanfare locally and it is the first in South Carolina.
