Norway's big oil producer Equinor bets €10bn on hydrogen            

Equinor, the flagship producer of oil and gas giant Norway, is investing billions of dollars in blue hydrogen on a bet that it can make the fuel more cleanly than anyone else.

The state-controlled oil firm is among energy companies across Europe stepping up plans for hydrogen as mounting pressure to fight climate change spurs massive shifts in investment. Equinor believes it has the edge in the race to commercialize the industry because it leaks less methane than its rivals.
