For hydrogen production they either need to
1 - convert methane CH via catalyst to hydrogen and carbon. Technologies can turn the carbon to graphite (hazer HZR.asx) or for building use (fly ash or bricks TAS.asx)
2 covert water H2O to hydrogen and oxygen
3 find natural hydrogen deposits

so compared to coal __ gas (methane) has plenty of upside for a greener future.
ive been a LTH of AJQ, down 75% ... so considering averaging down now.
