Green hydrogen can be cost competitive |
Since policymakers are demanding a drop in overall carbon emissions, the growth of hydrogen depends on its production becoming ‘clean’. Though other processes do exist or are emerging, near-future production of clean hydrogen will depend on two methods.
Blue hydrogen takes conventional production, largely reforming of natural gas, and adds another step—capture and storage of co-produced CO2 (CCS).
Green hydrogen dispenses with hydrocarbon feedstocks and splits hydrogen from water, utilising the process of electrolysis. For the hydrogen to be green, the electricity must be from renewable sources.
The cost of green hydrogen depends mainly on the cost of the electrolyser, the price of electricity used to power it and how often it operates (which impacts fixed cost recovery per unit of production).
Since renewable electricity is also becoming ever cheaper, most analysts forecast green hydrogen production will become cost-competitive with its blue cousin. Some predict that cost parity will happen in the sunniest and windiest countries within five years, and potentially everywhere from 2030.
