Towards the development of a hydRogen valley demonstratIng applications in an intEgRated EcoSystem in Greece

Project description

From traditional refinery to an advanced hydrogen-powered ecosystem

Greece is taking centre stage in the global shift to sustainable innovation. A convergence of industry, academia and research, technology providers, and public authorities has resulted in the TRIERES Hydrogen Valley, which is anchored around the Motor Oil Corinth Refinery complex as a future hydrogen generator. The EU-funded TRIERES project will support this endeavour: from short-sea ferries to public transport buses and passenger cars, it will showcase hydrogen's potential in mobility, complemented by collaborative efforts in the energy and industry sectors. The TRIERES valley is not confined by geographic limitations, revealing a dynamic perspective for supra-state and regional growth and versatility in end uses. The source of inspiration was the consortium's vision of transforming a fossil-fuel dependent economy through a cutting-edge energy and hydrogen ecosystem.


TRIĒRĒS is Greece’s first Hydrogen Valley brings together business, knowledge and regional interests. The TRIĒRĒS Valley starts as a small scale Valley but has a tremendous upward perspective over a large part of the Balkans, South-Eastern Europe and the wider area of Eastern Mediterranean. The Valley will be built around the nucleus of MOH’s Corinth Refinery complex. From a business perspective the project has strong transeuropean interest as 80% of the refinery sales are generated outside of Greece, rendering it internationally oriented by default. Creating and building a Valley using the refinery as Hydrogen generator accelerates the transition, with an annual production of 2,410 tons of Green Hydrogen that will be utilised in the production of low and no Carbon footprint energy and industrial products and will be injected in the natural gas grid creating a Hydrogen Backbone of full EU interest. High visibility actions in mobility will include one (1) short-sea ferry ship, three (3) public transport buses, and at least (two) 2 cars. Knowledge and innovations are spurred through the intensive collaboration with knowledge institutes and SME’s. The participation of the local and regional governments assures the component of public acceptance, understanding and advocacy, generating interest to many parties supporting regional economic growth. The learnings from HEAVENN and WIGA P&G Valleys will be replicated with the specific knowledge of the Greek and broader connected geographies. TRIĒRĒS entails an investment of 115 mil EUR (initially by project partners) up to 408 million EUR (potential direct/indirect leverage of investments). Several thousand people will be employed during the realisation of the valley project, which will promote new skills development. The consortium partners are creating a true new perspective in the region, transitioning from a traditional refinery complex to a state-of-the art future oriented energy and hydrogen ecosystem in the region.
