A study conducted as part of the EPHYRA project has introduced a new techno-economic methodology to optimize RES integration for green hydrogen production in Greece. The research, authored by Giannis Georgopoulos, Panos Papadopoulos, Georgios Mitkidis and Stella Giannisi has been published in the prestigious journal Communications Earth & Environment and is freely available via open access.

The team’s approach combines historical RES production data, electricity market dynamics, and the latest electrolyser performance data from the EPHYRA project. Their work focuses on developing a methodology for combining the optimal RES mix and assessing the critical role of regulatory incentives and RES curtailment utilization  for decreasing the Green LCOH.

The key finding is: Active electricity trading and regulatory incentives can significantly reduce the levelized cost of hydrogen, which makes green hydrogen a more economically viable solution for Greece’s energy transition.

The study is especially relevant as Greece and the broader South-eastern European  region look to scale up hydrogen infrastructure as part of broader EU climate and energy goals. By leveraging flexible market mechanisms and utilizing RES curtailments towards hydrogen production, the methodology provides actionable insights for policymakers, regulators, and industry stakeholders.

The results reinforce EPHYRA’s broader mission: to establish a replicable, cost-effective, and sustainable green hydrogen model integrated into industrial and energy systems.
