What are the primary goals of the TRIĒRĒS hydrogen valley?
  • To support the EU’s mission to scale up hydrogen ecosystems across Europe by establishing a strategic value chain for hydrogen production in the southeast Mediterranean, centered around the Motor Oil Hellas (MOH) refinery in Agioi Theodoroi, Greece.
  • To develop infrastructure and logistical models that optimize the green hydrogen supply chain, reduce costs and address bottlenecks, ensuring efficient green hydrogen distribution to off-takers.
  • To ensure the safe and efficient functioning of the hydrogen valley through the development of comprehensive safety management plans and monitoring of valley operations through the TRIĒRĒS valley digital twin.
How do the goals of the TRIĒRĒS hydrogen valley align with the EU's objectives?
  • Supporting the EU’s goal of decarbonizing the economy and reducing greenhouse gas emissions​​ by promoting the use of green hydrogen as a clean energy source.
  • Contributing to the EU’s energy security and reduces dependency on fossil fuels, aligning with the EU’s energy diversification strategies​​.
  • Focusing on innovative solutions for the production, storage and distribution of green hydrogen, in line with the EU’s drive for technological advancement and leadership in clean energy technologies.
What are the expected outcomes of the TRIĒRĒS Project?
  • The establishment of sustainable green hydrogen production methods through electrolysis, and the development of comprehensive hydrogen infrastructure, such as storage, distribution and refuelling facilities, that match the demand profiles of end users in the region.
  • Establishment of a green hydrogen market and further attraction of hydrogen stakeholders.
  • A broad dissemination of project results that will encourage investments in, and adoption of green hydrogen technologies.
What are some of the key components of the TRIĒRĒS Hydrogen Valley?
  • The project includes an electrolyser facility capable of supplying 2,410 tonnes/year of green hydrogen. This electrolyser, currently under development by Motor Oil Hellas through the EPHYRA* project, will utilize renewable energy sources to split water into hydrogen and oxygen, thereby generating green hydrogen. The green hydrogen produced meets stringent environmental standards and contributes to the EU’s sustainability goals.
  • Virtual Pipeline – A virtual pipeline involves the transportation of compressed hydrogen using three tube trailers to various end-users/off-takers. This method allows for flexible and scalable distribution of hydrogen without the need for fixed infrastructure.
  • Physical Pipeline – The physical pipeline will be a permanent infrastructure connecting the electrolyser directly to end users located in the proximity of the green hydrogen production unit, operated within the industrial complex of Motor Oil
  • Marine Applications – Hydrogen will be used to power a short sea ferry, demonstrating its viability as a clean fuel alternative in marine transportation.
  • Road Applications – The project will deploy hydrogen refuelling stations (HRS) for road mobility end users which include passenger cars and buses.
  • Energy Applications – Hydrogen will be supplied directly to the oil refinery of Motor Oil and the lubricant refinery of LPC, replacing conventional fuels currently used in their processes to produce greener products.

* EPHYRA project is supported the Clean Hydrogen Partnership and its members Hydrogen Europe and Hydrogen Europe Research under Grant Agreement No. 101112220.

Why is Greece such a suitable location for the Hydrogen Valley?
  • Greece’s strategic location in the southeastern Mediterranean offers excellent access to maritime and overland routes, ideal for hydrogen distribution across Europe and neighbouring regions.
  • With abundant solar and wind resources, Greece can produce green hydrogen via electrolysis, ensuring a sustainable and environmentally friendly hydrogen supply.
  • The Motor Oil Hellas (MOH) Refinery in Agioi Theodoroi and electrolyser currently under development through the EPHYRA, as well as existing port and logistics facilities in Greece aide green hydrogen production, storage, and transportation.
How does the project promote regional development?
  • By creating new job opportunities in construction, operation, and maintenance of the hydrogen valley’s many components, thus contributing to economic growth in the region.
  • By positioning the region as a hub for clean energy innovation, attracting further investment and skilled professionals.
  • By transitioning the region to a green hydrogen economy, reducing reliance on fossil fuels and improving its environmental quality. It also boosts the region’s competitiveness, attracting businesses, researchers, and investors interested in sustainable energy solutions.

What challenges need to be overcome for a hydrogen valley to be successful?
  • Developing infrastructure and logistical models to optimize the hydrogen supply chain is crucial. This involves solving equipment bottlenecks and developing the logistics for filling terminals and end users, as well as implementing both physical and virtual pipelines for efficient hydrogen distribution.
  • Developing a successful TRIĒRĒS Digital Twin model is essential to improving the efficiency and sustainability of green hydrogen production and distribution.
  • Developing a robust market for green hydrogen is a significant challenge as well. The TRIĒRĒS valley must not just ensure demand from existing end-users, but also help foster a viable economic environment for hydrogen production and distribution, including exploring low-carbon hydrogen pathways that may be complementary to green hydrogen.
  • Last but not least, supportive regulatory and policy frameworks must be in place as they are vital to the project’s success. This includes public governance policies and safety management plans, which are necessary to align with EU regulations and promote the adoption of green hydrogen.
What challenges does the TRIĒRĒS project face and how will they be overcome?
  • Inadequate governmental or private support and limited access to funding will be addressed by presenting the benefits of the Hydrogen Valley early on at dissemination events, inviting industrial players, ministries, authorities, funding bodies, and venture capital investors, and sharing results at popular conferences and tradeshows.
  • Limited availability of innovative technical components will be addressed through comprehensive technology reviews during the planning and deployment phase, ensuring timely implementation and procurement of necessary components and equipment.
  • Low hydrogen demand and lack of consumer awareness will be addressed by highlighting benefits at dissemination events, developing business models, and conducting professional communication campaigns and awareness activities, involving public authorities and associations in the External Advisory Board.
  • Legal and regulatory gaps and lack of incentives will be addressed by studying and updating the regulatory framework, developing public governance models for efficient market operation, and maintaining regular contact with authorities and policy makers, with support from the External Advisory Board.
What might the future plans for TRIĒRĒS be?

The project aims for near future global collaboration and the interconnection of hydrogen territories, positioning the TRIĒRĒS Valley as a key player in the global hydrogen market.

Continued efforts will be made to support the European Commission’s priority of scaling up hydrogen ecosystems across Europe through the development of emerging strategic value chains.

TRIĒRĒS will contribute to research and education, supporting workforce development and expertise in the field of green hydrogen. This includes integrating the research framework into master-level courses, such as “Supply Chain Dynamics” at the University of Groningen. The students will acknowledge and analyse the logistics models developed within TRIĒRĒS Hydrogen Valley. The course will take place in spring semester and is taught to approximately 70 students per academic year.

Future plans also involve:

    • Developing logistical models that will enable the operation and the seamless integration of the complete value supply chain from production to distribution and storage to end-use.
    • Defining and assess retrofit potential of current mobility assets (road vehicles and ships) to use green hydrogen, complying with all relevant restrictive limitations and regulations.
    • Learning the effects of infrastructure use for hydrogen use in maritime transport through FC powered ferry vessels and creation of roadmap to transition from fossil fuel-based to an emission-free water transport.
    • Development of novel business models (including traceability system i.e., with block-chain) for the green hydrogen supply chain.
