"Hydrogen has the potential to help bring more than half of the world’s
emissions down to zero, but to reach that potential it requires aggressive
government support, a dramatically improved value chain – and it needs
batteries to fail.
That last point is one of the most striking findings in a new series of reports
by Norwegian energy research house Rystad Energy, the last of which, on the
“battery society”, was released last week.
The reports examine three solutions to the problem of storage in an energy
system dominated by wind and solar: carbon capture and storage, hydrogen and
They conclude that battery technology is the most powerful of the three, having
the potential to help reduce to zero 78 per cent of the world’s emissions. CCS
could potentially help reduce 62 per cent of the world’s emissions, though it
is the least practical of the three.
Hydrogen could help reduce 51 per cent of the world’s emissions, but to reach
that level it would need to be used in areas where batteries currently have a
big edge, such as electric vehicles and electricity grid support."
