Constellation Energy gave an update on the hydrogen production demonstration project at one of its nuclear plants in New York.

Nine Mile Point Nuclear Plant became the first in the nation to generate its own hydrogen, Constellation and DOE announced.

Exelon (NYSE:EXC) said it will close its Nine Mile Point 1 nuclear plant next spring if New York has not guaranteed it a financial lifeline by September.

Upstate nuclear power plants would earn extra payments for emissions-free energy under a New York PSC staff proposal announced Thursday.

Nuclear supporters and New York Gov. Andrew Cuomo are trying to keep the plants running.
