Overview

EMEC was established in Orkney in 2003 to kickstart the marine energy sector in the UK and boost economic development in the Highlands and Islands in Scotland. EMEC helps reduce the time, cost, and risk of testing innovative sustainable technologies and is the world’s leading centre for demonstrating wave and tidal energy converters in the sea. Over the last 20 years, EMEC has supported the test and demonstration of emerging technologies, spanning marine energy, hydrogen offshore wind, and island decarbonisation through R&D projects totalling £538 million. EMEC is currently leading the Islands Centre for Net Zero (ICNZ), a pan-island distributed innovation centre that will support Orkney, Shetland, and the Outer Hebrides to become lighthouse communities in the energy transition.

Gap the project addresses

The global resource potential for marine energy is immense, with wave energy estimated at 29,500 TWh annually and tidal energy at 800-1200 TWh. Transitioning to a clean energy system, marine energy will bolster energy security, stimulate local supply chains, and create good jobs in coastal communities. At a local level, ocean energy presents significant opportunities for coastal communities to overcome the energy trilemma: reducing reliance on fossil fuels, investing in a domestic energy source, and offering security of supply as well as jobs and supply chain opportunities. EMEC provides the test space for the marine energy developer to deploy, learn lessons, innovate and scale.

Ownership model

EMEC is a private not-for-profit organisation, limited by guarantee.

Policy and funding

To date, £40M of public funding has been invested in EMEC’s test facilities.
A large part of the EMEC’s business model is undertaking R&D grant-funded projects across ocean energy, hydrogen, and islands decarbonisation. Funding mechanisms include European funding such as Interreg (pre-Brexit), Horizon Europe, UKRI, Innovate UK, and Scottish Government programmes. The revenue support mechanism Contracts for Difference (CfD) scheme has been instrumental to the development of the tidal energy sector across the UK and we support the idea of a ring fenced CfD for wave energy. A supportive policy environment for marine energy is crucial to help develop this emerging industry.

Impact to date

An economic impact assessment commissioned in 2023[1] showed that over 20 years of EMEC’s operation, activities have generated £263 million GVA to the Scottish economy. EMEC has also supported a PhD student who explored energy justice, focusing on communities in Orkney and renewables such as wind, green hydrogen, and marine energy. Her work will be published soon and can be shared on request.

Contribution to Just Transition

EMEC has a triple bottom line: people, planet, prosperity, which underpins everything we do, our mission, business model, and strategy. Through our work, we are actively addressing the following outcomes as identified by the Scottish Government Just Transition team:

  • Citizens, communities, and place: Part of EMEC’s remit is to ensure the creation of good, skilled jobs in Orkney.
  • Jobs, skills, and education: EMEC’s R&D in marine energy is contributing to the building of a local supply chain.
  • Fair distribution of costs and benefits: PhD student Lara Santos has been investigating energy justice for communities, exploring these ideas.
  • Business and economy: Marine energy is an emerging sector with green growth potential. In Scotland alone, marine energy could add £37bn GVA by 2050, creating 62,400 jobs. Around half of these jobs will be in device construction, with 15,000 high-value jobs located in coastal communities.[2]
  • Decarbonisation and efficiencies: EMEC’s R&D focuses on supporting emerging clean technologies that will help transition to a clean energy future. The Islands Centre for Net Zero project focusses on supporting decarbonisation pathways for Scotland’s islands Orkney, Shetland and the Outer Hebrides

Contribution to regional heritage

In Orkney, we have a rich heritage of harnessing the sea for various purposes, whether it be the fishing industry and herring, or transatlantic connections through the Hudson’s Bay Company. The islands also have a long history in energy, with the first grid connected wind turbine being tested at Costa Head in the 1950s[3]. Harnessing the sea for power from big waves and strong tides by deploying marine energy devices is another way of utilising the sea and adding to our heritage and forward-thinking attitude towards energy. EMEC and Orkney as an energy community have been the subject of several museum exhibitions, including “Energy Revolution: The Adani Green Energy Gallery” in the Science Museum in London[4], and more recently at a local level in the Stromness Museum’s 2025 exhibition, “Powered By People: Orkney’s Renewables Energy Story”.[5].

Benefits to the local area

An economic impact assessment commissioned in 2023 showed that, as a result of EMEC’s operations over the last two decades, £370 million GVA has been generated into the UK economy. Orkney alone has seen £130 million in GVA and the creation of 224 jobs. [6]

EMEC’s activity has fostered a cluster of activity in Orkney that is enabling other companies to develop and thrive, with the local marine renewables supply chain now exporting services and knowledge across the UK and around the world.

Harnessing the abundant resources available in the Highlands and Islands, EMEC is supporting the transition to a clean energy future and creating economic benefits in peripheral coastal communities.

Lessons learned

Fundamentally EMEC generates learning around our mission – to reduce the time, cost and risk of bringing new low carbon technologies to market through real-sea testing and demonstration. That includes:

  • Installability, survivability, operability, reliability, maintainability, scale-ability of new clean energy technologies all whilst aiming to reduce cost of energy (or better appreciate added value, such as the reliability of marine energy contributing to a future energy mixed based on intermittent sources of renewable power)
  • EMEC has taken that further through integrating wave and tidal energy into the grid/future energy systems incorporating green hydrogen production and battery storage
  • EMEC’s EIA demonstrates the economic benefits observed in Orkney.
  • As founders of the International WaTERS network EMEC have shared challenges and opportunities for replicating EMEC’s model internationally with other water and tidal energy test centres.

A report which EMEC produced last year in collaboration with Offshore Renewable Energy Catapult, commissioned by Crown Estate Scotland[7] highlighted:

Tidal energy has an important role to play in delivering Scotland’s net zero ambitions, particularly in terms of energy security and resilience. The UK Marine Energy Council is lobbying UK Government to set a 1 GW by 2035 target for tidal energy, within which the recommended ambitions for Scottish Waters are:

  • 200 MW by 2030 and
  • 700 MW by 2035

Due to the location of the tidal energy resource in Scotland, there is an opportunity to create local energy systems and support energy independence for remote or islanded communities. With evidence from the first projects already operating, this sector is directly supporting economic development in coastal communities across Scotland.

Replication and scaling

EMEC collaborates with an international network of wave and tidal test sites from across the world. We lead the International WaTERS forum[8], which organises a workshop every year to discuss challenges and opportunities in the sector.
EMEC is looking to expand its Fall of Warness test site in response to the tidal developers’ need to jump from single device testing to multi-device testing. This illustrates the progress being made in the sector and the continued need for R&D.

Case study showcase

Some projects were selected for more in-depth profile through examples that showcased their impact on communities, businesses and workers.

EMEC provided the following example.

PhD research by Lara M. Santos Ayllón has investigated how to anticipate energy (in)justice in relation to Orkney’s energy transition. Findings highlighted the importance of local agency and participation to mitigate the risks of future energy production. An unjust energy future would maximise renewable energy production across Orkney for profit and export while forgoing local communities and ecosystems. In contrast, just energy futures were broadly characterised as decentralised, prioritising energy security, affordability, local long-term jobs in traditional and new industries and local energy stewardship. Energy production would be capped to safeguard local identities and ecosystems, and energy wealth would be reinvested into ecosystems and communities. More broadly, results explicitly challenged the implicit association of “just transitions” to securing “identical outcomes”. They also highlighted the need for a just transition from innovation processes to commercialisation as future energy industries.
