it's a good goal to have. A large amount would be by HTOO and Acciona with PLUG !
The HTOO solution is so fast to deploy - the picture of their off grid site has just one BOP container I guess to compress and store the hydrogen. compare to PLUG or NEL or any other electrolyser supplier with all sorts of equipment surrounding the stacks.
These guys seem to understand how to influence governments and get things done- the Bakersfield project will start to raise eyebrows I am sure.
