Simultaneity of green energy and hydrogen production: Analysing the dispatch of a grid-connected electrolyser

Hydrogen is a promising supplement in future energy systems with high penetration rates of renewable (RE) generation. As conversion technology between the two secondary carriers, hydrogen and electricity, particularly grid-connected electrolysers, have role to play. During market ramp-up, electrolysers could cause unwanted side-effects through inducing additional CO2 emissions power sector. Since reduction constitutes overall goal, simultaneity obligation RE generation production discussed prevent indirect from an electrolyser's consumption. The paper presents model framework including mixed-integer linear program Markov chain Monte Carlo simulation for stochastic electricity prices assess dispatch. Within case study German market, effect on dispatch assessed. results show that reduces emission intensity while constraining profits. choice interval length affects average contribution margin corresponding profit at risk, which fluctuating Regulations aiming interface must consider trade-off economic viability, full load hours, associated electricity-based hydrogen.
