Abstract
Green hydrogen holds promise as a zero-carbon energy carrier if production costs fall
low enough to achieve cost-competitiveness with alternatives. We specify reducedform marginal effect relationships that capture the underlying dynamics of existing
structural models of hydrogen production via electrolysis. These specifications provide
the marginal effect of electricity costs, electrolyser capital costs and capacity utilisation
factors on the cost of producing hydrogen. And we use them to identify the potential
combinations of cost components that meet threshold production costs under which
green hydrogen will be cost-competitive. In the near-term, there is particular promise
for low cost green hydrogen production where electrolysers are co-located with
renewable energy parks to use electricity that would otherwise be curtailed. Or when
they operate during periods of low or negative prices in electricity grids. Green
hydrogen stand-alone operations could be commercially viable with continued
reductions in renewable energy generation and electrolysers
