For years, we’ve been told that tidal energy, like other forms of renewable power, is a promising but slow-moving giant that’s still years away from mainstream adoption. But the truth is, tidal energy is not only more advanced than we think, but it’s also already making waves in the energy industry.

In fact, tidal power plants, which harness the predictable and reliable energy of ocean tides, are not just a novelty of the future – they’re already being deployed around the world, with the first commercial tidal array in the UK’s Pentland Firth generating enough electricity to power over 180,000 homes.
So, what’s holding tidal energy back from becoming a major player in the global energy mix? One major hurdle is the high upfront costs associated with building these massive underwater turbines. But, as with any emerging technology, economies of scale are driving prices down, making tidal energy more competitive with fossil fuels.

Another challenge is the need for specialized infrastructure, including massive underwater foundations and subsea power transmission lines. However, companies like OpenHydro and Verdant Power are pioneering innovative solutions, such as floating foundations and modular turbines, that can be easily deployed and maintained.
Despite these hurdles, the benefits of tidal energy are undeniable. Unlike solar and wind, tidal power is predictable and reliable, with a 25-year lifespan that makes it a low-maintenance option. It also has a much higher capacity factor than many other forms of renewable energy, meaning it can generate electricity at or near full capacity for a greater percentage of the time.
Tidal energy also offers a range of benefits that go beyond just the environment. In coastal communities, it can provide a new source of local employment and economic growth, while also helping to mitigate the impacts of climate change.
So, what’s next for this exciting technology? As governments and companies invest in tidal energy, we can expect to see a surge in innovation and deployment in the coming years. In fact, the UK’s Crown Estate has already committed to investing £1 billion in tidal energy projects, while the US Department of Energy has launched a new initiative to support the development of tidal and ocean energy technologies.
As the world transitions to a low-carbon future, tidal energy is poised to play a major role. It’s time to stop thinking of it as a niche player and start recognizing it as a game-changer – the key to unlocking a more sustainable, reliable, and resilient energy system for generations to come.
