For decades, we’ve been told that tidal energy is a fringe player in the renewable energy space, a novelty that’s too expensive and too complex to ever become a significant contributor to our global energy mix. But the truth is, tidal energy is about to experience a seismic shift that will make it a game-changer in the fight against climate change.

The reason for this sudden shift is the rapid advancement of technology, particularly in the field of floating tidal stream generators (TSGs). These innovative devices can harness the power of ocean tides to generate electricity, and they’re about to become cheaper, more efficient, and more widely adopted than ever before.
One of the biggest advantages of tidal energy is its predictability. Unlike wind and solar power, which can be affected by weather patterns and seasonal changes, tidal energy is as reliable as a sunrise. The oceans’ tides are influenced by the gravitational pull of the moon and sun, creating a predictable and reliable source of power that can be harnessed 24/7.

But what’s really driving the tidal energy revolution is the cost. The price of TSGs has dropped dramatically in recent years, making them competitive with other forms of renewable energy. According to a report by the International Renewable Energy Agency (IRENA), the cost of tidal energy has fallen by as much as 50% in just the past five years. This is largely due to the development of more efficient turbines and the use of advanced materials, such as composites and robotics.
Another key factor driving the growth of tidal energy is the emergence of innovative financing models. Gone are the days of traditional project financing, where developers had to rely on government subsidies or private investors to fund their projects. Today, tidal energy projects can be financed through a range of innovative instruments, including green bonds, crowdfunding, and private equity.
As the technology continues to improve and the cost comes down, tidal energy is poised to play a bigger role in the global energy mix. In fact, a report by the National Oceanic and Atmospheric Administration (NOAA) estimates that tidal energy could provide as much as 10% of the world’s electricity by 2050.
So, what’s holding tidal energy back? One major obstacle is the permitting process, which can be slow and bureaucratic. Developers must navigate a complex web of regulations and obtain permits from multiple government agencies before they can even begin construction. This can take years, if not decades, and can be a major barrier to entry for new players in the market.
Despite these challenges, the tidal energy industry is rapidly expanding. In the United Kingdom, for example, tidal energy is already generating enough electricity to power over 100,000 homes. And in the United States, companies like Verdant Power and OpenHydro are leading the charge in the development of tidal energy projects.
As the world continues to grapple with the challenges of climate change, tidal energy is poised to play a major role in the solution. It’s time to rethink our assumptions about this innovative source of power and recognize its potential to transform the way we generate and consume energy. The underwater revolution is coming – and it’s about to change everything.
