A Call for Regulatory Reform to Unlock Scotland’s Tidal Energy Potential

A new report from the European Marine Energy Centre (EMEC) calls for coordinated regulatory reform to unlock Scotland’s tidal energy potential while addressing environmental concerns over harbour seals.

According to EMEC, the new report published today, May 13, Managing the Consenting Risk of Harbour Seal Collision in the Scottish Tidal Energy Industry, outlines key recommendations for adopting a science-led and proportionate approach to the consenting process, aimed at unlocking the full potential of tidal stream energy through responsible, scaled deployment.

Despite the lack of evidence for seal-turbine collisions, the industry continues to face long lead-times and uncertainty under the current regulatory framework, particularly in the Pentland Firth and Orkney Waters, where harbour seal populations are in decline, according to the report.

Funded by Crown Estate Scotland and Highlands and Islands Enterprise, the report was developed under the Tidal Industry Seal Project (TISP) with input from eight industry and consultancy organisations, EMEC noted.

The report consortium includes Xodus Group, Carronside Consultancy, SAE Renewables, EMEC, Eurona Consultancy, Burges Salmon, Orbital Marine Power, and Nova Innovation.

Donald Leaver, Environment and Consents Manager at EMEC, noted that advancing tidal energy requires joint efforts to determine whether seal collisions with turbines pose a concern.

“With various new projects in the Pentland Firth and Orkney Waters due to be built out over the coming decade, supporting Scottish and UK government policy ambitions for energy security and climate resilience, it is vital this consenting uncertainty is resolved in a collaborative, science-led manner to enable sustainable development alongside the protection of our marine ecosystems,” Leaver noted.

Fraser Johnson, O&M Manager at MeyGen, highlighted how environmental risks are assessed and managed within the tidal energy sector. Johnson also emphasised the need for an updated consenting system that reflects current evidence and supports the scaling of this essential technology. He noted that tidal stream energy has already shown its ability to deliver reliable, renewable power and foster a thriving industry.

“We must ensure we put in place a framework that enables responsible growth, builds trust, and delivers long-term value across communities, the environment, and those investing in a more resilient energy future,” Johnson concluded.

According to data from Scottish Renewables, almost two-thirds of companies in Scotland’s clean energy supply chain are investing in skills, capabilities, and facilities to prepare for growth in the renewable sector over the next three to five years.

A recent report from the University of Edinburgh (UoE) revealed that Scotland’s tidal stream and wave energy sector could generate over £8 billion (almost $10 billion) in economic benefits and create more than 15,000 jobs by 2050 if the country retains its leadership position in the field.

In January, a parliamentary debate brought the future of the UK’s marine energy sector into focus, as Members of Parliament (MPs) called for enhanced government support to harness the country’s tidal and wave energy potential. The discussion underscored the need for funding and initiatives to solidify the UK’s position as a global leader in marine energy technology.
