GreenH2Atlantic

GreenH2Atlantic is a large-scale renewable hydrogen initiative centered in Sines, Portugal, structured as a multi‑partner industrial consortium. The project aims to produce green hydrogen via electrolysis powered by renewable electricity, supporting the decarbonization of the Sines industrial cluster and surrounding value chains. It is positioned to repurpose legacy energy infrastructure at the port and former thermal power plant site, creating new hydrogen production and logistics capacity.

Planned activities include deploying a utility‑scale electrolyser (with an initial capacity target around the 100 MW range) and developing associated storage, distribution, and end‑use integration. Anticipated offtake pathways include supplying hydrogen for refining and chemical processes, power and heat applications, mobility, and potential blending into the natural gas network. The project has received support under European Union funding mechanisms related to the energy transition. For the chemical industry, GreenH2Atlantic is intended to provide a local, low‑carbon feedstock alternative to fossil‑based hydrogen, enabling emissions reductions in various process industries in the Atlantic corridor.
