Fig. 3: Cost impacts of varied PGP system integration strategies.

From: Assessment of carbon-abatement pricing to maximize the value of electrolytic hydrogen in emissions-intensive power sectors

Fig. 3

The figure illustrates the changes in electricity system costs and the resulting PGP system’s levelized cost of hydrogen value (LCHV) from a hydrogen production via excess renewable curtailment compared to price arbitrage, and b fuel cell electricity dispatch during peak periods compared to trading arbitrage. The electricity costs are benchmarked against the case without the PGP system in the power sector. A risk-averse PGP system integration strategy involves supplying only excess renewable energy to the electrolyzer and dispatching the fuel cell during periods of peak demand.
