Energy from the Earth's Tides Understanding Tidal Power

Using the Earth's Tides to Generate Electricity

Earth's tidal currents are caused by the gravitational pull of the moon. Tides remain constant for about six hours before briefly pausing and then shifting direction for another six hours. Tides are predictable and as far as we know inexhaustible, which means that energy produced from tides is renewable and can provide baseline, 24/7 power.

There is a great deal of interest in developing tidal power, particularly in Europe, where the first commercial tidal power plant prototype began operating in 2003 off the coast of Norway. In May, 2008, the first commercial marine current generator went into operation at Strangford Lough in Northern Ireland. This generator is expected to produce 1.2 MW of electricity, supplying about 1,000 homes with power. This turbine cost $20 million and operates when tides are moving at speeds of at least 2.3 mph. In modern times, in 2018 we can DIY our hydro generator, here is an example about home hydroelectric power this generator can provide electricity to one whole household.

A tidal barrage is a type of dam built to utilize the differences in high and low tides to generate electricity. They have the same type of negative impacts as other types of dams such as high costs, lack of viable dam sites and environmental degradation. The US has no tidal barrages and there are only a couple currently operating in France and Canada. Russia and the UK have the potential to development barrage systems, but have not yet taken steps toward doing so.

Tidal stream systems are a newer form of hydropower that convert tidal energy to electrical power much in the same way that wind turbines convert wind power to electricity. The greater density of water means that energy can be produced at much lower velocities than is needed to produce energy from wind. The development of tidal stream systems may produce large amounts of baseline energy. It is estimated that the tidal currents around the UK, if harnessed, could provide 48-terrawatt hours of electricity per year. Worldwide estimates for tidal power are about 3,000 gigawatts.

Location is crucial in picking sites for tidal stream systems. Tidal stream systems need a minimum tidal velocity of 1 m per second. The stronger a tidal current is in either height or velocity, the more energy can be produced from the current. Good sites for these systems include Pembrokeshire and the Severn in Wales, the Cook Strait in New Zealand, the Bay of Fundy, New York City's East River, San Francisco Bay and the Channel Islands.

Water density has led to some problems in large scale deployment of tidal stream systems due to broken turbines or problems with mooring turbines in turbulent ocean waters. Some other drawbacks to developing ocean power stations include the corrosion of machinery by salty seawater, the sheer force of the oceans currents that can damage machinery, the cost of building a grid to bring electricity to the continents, and the cost of building the machinery, which is currently very high.

Another form of ocean energy that may see development in the future exploits temperature differences in the world's strongest areas of oceanic circulation such as the Gulf Stream. Other thermal technologies use the difference between surface ocean temperatures and temperatures in the deep ocean to produce power. This technology is currently still in the very earliest stages of experiment and prototyping.

The cost of electricity that may be produced by tidal farms is projected to be much higher than what consumers are currently paying for electricity. There are also groups that are concerned with possible impacts on sea animal activities and loss of recreational areas.

What people are saying

  • Qorax Energy is a creative and dynamic partner as we combat Somaliland’s high unemployment and high costs of electricity.

    Dr. Ahmed Hussein Esa, President of Abaarso Tech University
  • Qorax Energy’s approach presents great opportunity for the people of Somaliland.

    Adam Diriye Egal, Somaliland's Deputy Minister of Commerce
  • Qorax’s efforts coincide with the Ministry of Energy’s plans to guide the utilization of solar power and support the Somaliland government’s environmental goals.

    Suleiman Abdullahi, Somaliland's Director of Energy

Portfolio

600 million live without access to clean, affordable lighting in Sub-Saharan Africa. But the reality is that 25% of these people will never receive solutions because they live in areas that are perceived as too risky or remote. Qorax was founded to bring vital electricity access here, first and foremost in Somalia, Somaliland and the DRC.
