![]() One of the main reasons for this is because water is so dense - almost 800 times more dense than air. Tidal power plants are able to produce high amounts of electricity. It also makes it easy to know how much power will be produced by turbines, since the power of the tides and currents can be forecasted accurately. Low and high tides follow well-known cycles, making it easier to know when power will be produced throughout the day. ![]() In addition to being a renewable energy source, tidal power stations do not emit greenhouse gasses during electricity generation.īecause greenhouse gas emissions are one of the leading causes of climate change, finding zero-emission energy sources is more important than ever. The gravitational pull from the sun and the moon, which controls the tides, won’t cease to exist anytime soon. So, as you are harnessing energy from the changing tides, you don’t decrease the amount of energy the tides can produce in the future. Tidal energy is a renewable source of energy, which means the energy doesn’t deplete as it is used. The turbine turns a generator that then produces electricity.Ĭheck out our article on how tidal power works for a more in-depth explanation. As the currents and tides change, the moving water pushes the blades of the turbine. Tidal turbines harness tidal energy similarly to how wind turbines capture wind energy. Tidal power can be captured by using different types of technologies, such as tidal barrages, tidal stream generators, and tidal fences.Īll of these types of tidal energy plants make use of tidal turbines, so it's most important to understand how a turbine can capture the kinetic energy within the tides for energy production. While interest in marine-based energy systems appears to be growing, the current footprint of the industry and its technologies remains small.įigures from Ocean Energy Europe show that only 260 kilowatts of tidal stream capacity was added in Europe last year, while just 200 kW of wave energy was installed.īy contrast, 2020 saw 14.7 gigawatts of wind energy capacity installed in Europe, according to industry body WindEurope.Tidal power is a renewable energy source that turns energy created from changing tides and currents in the ocean ocean into usable electricity. Back in March, the Port of London Authority gave the go ahead for trials of tidal energy technology on a section of the River Thames, a move which could eventually help to decarbonize operations connected to the river. There's also potential when it comes to rivers. The project will be based on the Isles of Scilly, an archipelago located off the southwest coast of England, and led by Isles of Scilly Community Venture, Planet A Energy and Waves4Power. In April, it was announced that a yearlong research project focusing on the potential of tidal, wave and floating wind technology had secured support from Marine-i, a program centered around innovation in areas such as marine energy. as a whole is home to a number of projects related to marine energy. Looking to the future, Orbital Marine Power said it was "setting its sights" on the commercialization of its tech via the deployment of multi-megawatt arrays. Michael Matheson, the Scottish government's Cabinet secretary for net zero, energy and transport, said his country was "ideally-placed to harness the enormous global market for marine energy." "The deployment of Orbital Marine Power's O2, the world's most powerful tidal turbine, is a proud moment for Scotland and a significant milestone in our journey to net zero," he went on to add. The Scottish government has also provided £3.4 million (around $4.72 million) of support through its Saltire Tidal Energy Challenge Fund. In a statement, Orbital Marine Power's CEO, Andrew Scott, described Wednesday's news as "a major milestone for the O2."įunding for the O2's construction has come from public lenders via Abundance Investment. The turbine is also set to send power to a land-based electrolyzer that will generate so-called green hydrogen.
