Johnson Matthey (JMAT.L) said on Monday it has signed a three-year supply agreement with Norwegian firm Hystar AS to ramp up green hydrogen production as the British company shifts focus to a sector that is drawing big investments.

The announcement comes as companies globally are increasing investments in green hydrogen, a zero-carbon fuel made by using renewable power from wind and solar energy to split water into hydrogen and oxygen, in their quest for energy which does not add to global warming.
