Ammonia can be used as a way to transport hydrogen molecules
Grey hydrogen should act as bridge to blue and green
Fuel can be used to stimulate demand while the costs of blue and green hydrogen are brought down
Grey hydrogen should act as a stepping stone for the development of blue and green hydrogen, according to panellists at a Reuters event. Currently, 97pc of the hydrogen produced in the world is grey hydrogen — but a number of nations and regions around the world are developing hydrogen strategies because of the potential of the green and blue variety to act as low carbon fuels for the industrial and transport sectors. “We do see blue and green hydrogen developing out of grey—it can be a good starting point,” says Paul Bogers, vice-president of hydrogen at Shell. “We do see blue and green hydrogen developing out of grey” Bogers, Shell Grey hydrogen production can be used to meet and b
