- Portugal Offshore Wind, Green Hydrogen, and Sustainable Fuels: Power-to-X PathwaysPublication . Simoes, Sofia; Portillo, Juan C. C.; Simões, Teresa; Estanqueiro, Ana; Catarino, Justina; Costa, Paula; Oliveira, Paula; Ribeiro Pinto, Paulo Jorge; Lopes, Fernando; Lopes, Tiago; Gano, António; Duarte de Castro Fontes, Maria MargaridaABSTRACT: Portugal has a vast coastal area and significant offshore wind resources. The country has set ambitious targets and designated specific areas for offshore wind development. Current national policies are actively encouraging investment in these projects. This report compiles the latest strategies for offshore wind and green hydrogen in Portugal. It introduces the Power-to-X (P2X) concept, explores potential offshore wind-based P2X business models, and outlines the key processes and technologies involved. It also maps potential consumers of green hydrogen, along with the associated supply chains for hydrogen and sustainable fuels. A techno-economic analysis was conducted to identify viable pathways for Portugal. This involved selecting one of the planned offshore wind zones and, based on its location and potential capacity, determining the optimal onshore site and scale for a hydrogen and sustainable fuels hub. The report presents a comparative evaluation of seven scenarios, offering valuable insights for both public and private sector stakeholders.
