Pioneering Renewable Hydrogen for a Sustainable Energy Future

EPHYRA aims to enhance European synergies on the globally expanding hydrogen market and build a unique value proposition on industrial symbiotic renewable hydrogen production.

Electrolyzer upgrade

Its scope is to demonstrate the integration of a first of-its-kind renewable hydrogen production facility at industrial scale in South-East Europe: a renewable hydrogen electrolysis plant within MOH’s Corinth refinery, originally designed at 30 MW and now being implemented at 50 MW capacity.

The expansion was secured through additional financial support from the Recovery and Resilience Facility and aligns with the project’s long-term decarbonization vision.
The electrolyser will enter a commercial operation for at least 2 years to supply hydrogen to refinery’s processes and external end-users.

The Pilot Plant

Motor Oil’s Refinery,
Agioi Theodoroi, Corinth

(70km from Athens)

Motor Oil’s refinery is Greece’s largest privately owned industrial complex and one of Europe’s most modern refineries, with a Nelson Complexity Index of 12.61.
It processes diverse crude types, produces high-value oil products meeting EU and global standards, and is the only Greek refinery producing base oils.
With advanced technology, it adapts product mixes to market needs, ensuring competitive refining margins and efficient global distribution.
The large-scale electrolysis will be demonstrated within the refinery, integrated with industrial operations, and coupled with renewable energy production, and be symbiotically embedded to a circular economy concept.
A Circular Economy Approach to Renewable Hydrogen Production
The project will be one of the enablers of the production of green hydrogen, increasing competitiveness and circular economy transformation.

Revolutionizing Green Hydrogen Production

  • Sets the benchmark for large-scale, cost-competitive renewable hydrogen production. Achieves TRL 9 commercial implementation.
  • Becomes a recognized showcase for green hydrogen viability.

Transforming Europe's Energy Landscape

  • Offers practical pathways for green hydrogen deployment in hard-to-decarbonize sectors.
  • Creates consistent demands to accelerate renewable energy adoption and transition.

Advancing Energy Independence and Decarbonization

  • Reduces reliance on imported fossil fuels while decarbonizing energy-intensive industries.
  • Lays the groundwork for a hydrogen market in Greece, enabling hydrogen integration across industries, energy networks, mobility solutions, and synthetic fuel production.

Scalability and Investment in Green Hydrogen

  • Offers practical pathways for green hydrogen deployment in hard-to-decarbonize sectors.
  • Creates consistent demands to accelerate renewable energy adoption and transition.

The successful scale up from 30 MW to 50 MW demonstrates the project’s adaptability and strengthens the case for replicability across larger industrial sites in Europe.

Proud to Be Part of the TRIĒRĒS Valley

EPHYRA is the flagship project anchoring the TRIĒRĒS Valley – Greece’s first hydrogen valley initiative and a strategic blueprint for clean hydrogen deployment across Eastern Mediterranean. Located at the Motor Oil Hellas (MOH) refinery in Agioi Theodoroi, EPHYRA provides the green hydrogen that will power the TRIĒRĒS ecosystem, enabling new markets and end-uses in mobility, shipping, industry, and synthetic fuels.

The TRIĒRĒS Valley is a major step forward in building an integrated hydrogen value chain – from production to end-use, spanning Greece, Cyprus, Egypts and neighboring regions.

At the central of this transformation, EPHYRA delivers renewable hydrogen directly into this ecosystem, effectively opening Greece’s hydrogen market and demonstrating how industrial decarbonization can be the launchpad for national energy transition.

EPHYRA’s electrolyser upgrade from 30 MW to 50 MW strengthens its role as a foundational infrastructure asset – enhancing flexibility, increasing production potential, and better aligning with future hydrogen use cases planned within the TRIĒRĒS Valley.
