Why the negativity here? What people mostly worry about (fossil fuel being used to produce electric then produce hydrogen in the background) is simply explained in this line in the article

"The carbon-free rigs will pack 50 kilos of hydrogen zapped from water using electricity from the refinery’s dedicated solar power plant."

hence __green__ hydrogen.

On the contrary, I think storing energy in hydrogen has more potential in long term compare to lithium or any other type of batteries that rely on ores we need to dig up, refine and dump as waste after a couple of years, no?
