ITEG: Integrating Tidal energy into the European Grid

Project Summary

ITEG will develop and validate an integrated tidal energy and hydrogen production solution for clean energy generation to be demonstrated in Orkney. The project addresses energy related carbon emissions in North West Europe and will tackle grid export limitations faced in remote communities.

Led by the European Marine Energy Centre (EMEC) in Orkney, the ITEG project brings together partners from across the UK, France, Belgium and the Netherlands and will adopt three low carbon technologies (tidal turbine, electrolyser and Energy Management System)

The cost of pre-commercial demonstration for ocean energy is high and investors are reluctant to invest until the technology has been proven in the sea at scale. ITEG sets out to drive down these costs through the development of an integrated hydrogen production solution.

The integrated solution combines Orbital's next generation 2 MW floating tidal energy converter, the Orbital O2 2MW, with a custom built 500kW AREVA H2Gen electrolyser and an onshore energy management system (EMS) to be deployed at EMEC's hydrogen production site on the Orkney island of Eday.

The EMS will support the production of hydrogen by routing any excess energy generated by the Orbital O2 turbine on EMEC’s Fall of Warness tidal test site to be used to power an AREVA H2Gen electrolyser, the first to be deployed in the UK. 

Project objectives

  • Develop and validate an integrated tidal energy and hydrogen production solution for clean energy generation in remote areas
  • Open new market opportunities for the ocean energy sector through hydrogen production and energy storage
  • Optimise the EMS and fast-track a clean energy generation, management and storage solution towards commercialisation 
  • Build a roadmap to support the replication of the integrated solution in other remote, grid restricted areas

The following graphic shows how the three low carbon technologies will form an integrated hydrogen production solution;

NWE making an impact!

, Tourcoing, France

The Interreg North-West Europe (NWE) programme is pleased to announce its first impact event on 4 and 5 December 2019, which will take place in Tourcoing (Lille agglomeration, Hauts-de-France) at La Chaufferie. Over a day and a half, this transnational event will focus on the results achieved by the 83 NWE projects funded so far, and how to further support their uptake and impact. Through a wide variety of sessions and formats, the programme will offer unique opportunities for participants to network, exchange and explore new potential collaborations.

Seanrgy 2019

, Dunkerque, France

Seanergy is the international forum dedicated to Offshore Wind and Marine Renewable Energy. Seanergy aims to structure and promote the MRE sector through the field of offshore wind – fixed and floating – tidal energy, floating solar, wave energy, Marine Thermal Energy (MTE)… Seanergy gathers around 250 exhibitors and more than 3500 international actors of the MRE field (politics, ordering institutions (energy operators and industrials), technological experts, NGOs, researchers, investors and subcontractors), around an exhibition area, conferences, business meetings and industrial sites’ visits; with the goal of reinforcing synergies between all the actors of this industry, accelerating its structuration and promoting its development, in France and worldwide. The purpose of the event is to accelerate development by stimulating collaboration between companies, researchers and development centres. It also targets engagement of operators with experience in related marine and power industry sectors.

Scottish Hydrogen and Fuel Cell Association Annual Conference 2018

, Dundee, Scotland

The 10th Annual Scottish Hydrogen & Fuel Cell Conference takes place on Wednesday 26th September 2018 in Dundee, one of Scotland’s most vibrant cities. This one day conference will highlight the substantial progress being made in Scotland with the deployment of hydrogen and fuel cells as key components of an integrated low carbon and zero emission system. Speakers will provide updates on use of hydrogen and fuel cells to enable more renewable energy to be captured and used effectively, coupling energy with transport, and tackling ‘hard to treat’ areas such as heat and industry. The 2018 SHFCA conference will share best practice for hydrogen and fuel cell technologies in delivering low carbon energy systems. During this event we will: Showcase Scottish innovation with deployment of hydrogen and fuel cell technologies Highlight the importance of partnership working and international collaboration Present current thinking and identify future trends across our industry
