Scotland is making waves in the renewable energy sector, and this time, it’s not just wind power stealing the spotlight. Tidal energy—predictable, reliable, and potentially transformative—is now firmly in the country’s crosshairs as officials, businesses, and investors explore how best to harness its potential.
A newly released report from the University of Edinburgh’s Policy and Innovation Group, commissioned by Scottish Enterprise, estimates that Scotland could generate up to 4.3 gigawatts of tidal energy by 2050. The economic impact? A staggering £4.5 billion in GVA benefits and nearly 6,000 new jobs across the country.
The Predictability Advantage
Tidal energy’s main selling point is its predictability. Unlike solar and wind, which fluctuate with the weather, tides operate on a schedule that’s been charted for centuries.
“We know exactly when the tide will go in and out,” said Johanna Money, an energy transition specialist at Scottish Enterprise. “That kind of reliability offers significant benefits to the national grid.”
The UK government has taken notice. Under the Contracts for Difference (CfD) scheme, funding has been set aside for a new wave of tidal projects, ensuring that Scotland remains at the forefront of this emerging industry.
Scotland’s Pioneering Tidal Projects
Some of the world’s most ambitious tidal energy initiatives are already making strides in Scottish waters:
- MeyGen (Pentland Firth) – The largest tidal energy array in the world.
- Nova Innovation (Shetland) – Pioneering small-scale tidal turbines.
- Orbital Marine Power – Developing floating tidal turbines that could revolutionize offshore power generation.
“These projects showcase Scotland’s expertise and innovation in tidal technology,” Money added. “With government backing, we have a strong pipeline of developments set to go live by 2030.”
A Boost for Coastal Communities and Supply Chains
Tidal energy isn’t just about electricity—it’s also about jobs and economic development. Much of the engineering expertise from Scotland’s oil and gas sector is transferable to tidal energy, creating a natural transition for workers in the industry.
“We’re seeing coastal communities benefit directly from these projects,” said Eileen Linklater of the European Marine Energy Centre (EMEC) in Orkney.
Key Economic Benefits:
- £370 million added to the UK economy from tidal energy testing.
- £263 million of that figure staying within Scotland.
- £130 million specifically benefiting Orkney.
- More than 200 new jobs created in the process.
“These are high-value jobs that help retain young people in Orkney,” Linklater added.
The Global Tidal Energy Market
Scotland isn’t just looking inward—it’s also setting its sights on international expansion. Experts estimate there’s around 120 gigawatts of tidal energy potential worldwide. If Scotland maintains its leadership in the sector, it could play a key role in a market valued at $136 billion.
“By exporting our technology and expertise, we can establish Scotland as a global hub for tidal energy innovation,” Money said. “This is a once-in-a-generation opportunity to lead the way.”
With ambitious targets and strong support from both the government and private sector, Scotland’s tidal energy sector is gaining momentum. The next decade will be crucial in determining whether the country can turn its vast ocean resources into a long-term source of clean energy and economic growth.
