摘要

Renewable (Green) hydrogen is expected to play a key role in the green energy transition, but the levelized cost of hydrogen remains high. The European Union’s Delegated Regulation 2023/1184 outlines criteria for classifying hydrogen as green. This analysis presents a technoeconomic methodology based on Green Power Purchase Agreements, using market projections, renewables profiles, and data from a 30 MW electrolyzer project in Greece, where temporal correlation requirements of the Delegated Act apply. Results indicate that in the case of Greece, regulatory incentives, active trading, and efficient resource use can reduce hydrogen cost. In our case study, a decrease of 1.2 Euros per kg can be achieved, for proton exchange membrane electrolysis and alkaline electrolysis technologies.
