The technology involved in using H2 as an energy source can be costly for several reasons. Their use is considered to have zero-carbon operations but only when green H2 is used, meaning that it is produced using processes powered by renewable energy such as wind and solar. That said, the most common production method currently used involves burning natural gas, a fossil fuel.
Currently, costs of producing fuel cells and of producing H2 are among the leading barriers to growth of H2 use

PSR Analysis: Until these costs come down significantly (and remain low after government subsidies end as they inevitably will) H2 will struggle to compete with EVs. PSR
