A few days ago, the President of South Korea, Lee Myung-bak has officially inaugurated what he claims to be the world’s largest …
Scotland has recently installed the first grid-connected, commercial-scale tidal turbine, thus making great progresses in the marine energy industry. Called 1MW AR1000, …
Tides are capable of producing electricity and are more predictable than wind or solar power. Just like wind turbines in the sea, they need to stand on very firm ground. All of that is known from the 60’s, but what researchers didn’t know was how to make that cost-effective, the main reason why development lagged behind.
Wind power had always been considered our salvation from peril, our last and most accessible “renewable” resource on this planet. Well, Axel Kleidon, a scientist at the Max Planck Institute for Biogeochemistry in Jena, Germany, has another theory: wind and wave power are not so renewable and infinite, after all.
The Scottish Government is about to approve the world’s largest tidal power project that will be built in the Sound of Islay. According to ScottishPower Renewables, the project is expected to cost about £40 million ($65 million) and will be capable of generating enough energy to power around 5,000 homes.
The Swedish tidal energy device developer Minesto has revealed its latest technology using underwater kites to produce clean electricity. Unlike other similar systems, the new technology, called Deep Green, is capable of operating in slower currents.
Atlantis Resources Co, a London-based marine energy developer, had the idea of building a tidal power plant with an initial capacity of 50 MW. Gujarat, an Indian state, has already made some plans for the installation of the first commercial tidal power plant in India. The project will be organized in partnership with Guajar Corporation Limited.
An interesting concept for producing energy has caught my eyes today, and I think it might even work. The devices that Phil Pauley conceived are called “Hydrostatic Turbines”, and operate at high water depths.
There has recently been an interesting debate whether engineers should change the shape of tidal turbines because of the negative effects these would have on the environment, and, more specifically, the fish. Current tidal turbines’ blades are made using the pattern used in wind turbines.
A wave power test plant has been deployed on Nov. 17 two miles offshore of Fort Pierce, Fla., and is now being tested by its designers, researchers from Florida Institute of Technology’s College of Engineering. The power plant has been named “Wing Waves,” and works by harvesting the elliptical motion of waves 30 to 60 feet deep, and converting it into electricity.
Underwater turbines are one of the many alternative energy sources, a technology which has seriously challenged scientists since the beginning, due to the low velocity associated with many tidal flows and the difficulty of extracting useful energy from low speed flows using current designs.
The newest affordable clean energy source that scientists have laid eyes on is the one provided by hydrokinetic systems such as ocean waves and free-flowing rivers. Researchers estimate that this ÃƒÂ¢€Ã…â€œfreshÃƒÂ¢€ source of energy could supply electricity to meet up to 10% of America’s power needs.
The South West Regional Development Agency from UK is analyzing the results of a study according to which the South West coast could generate 9.2 gigawatts of electricity, being enough to power five million homes.
Last year, the Ocean Power Technologies (OPT) company has developed a tidal power generator that has now been connected to the energy grid at the Marine Corps Base Hawaii as part of the firm’s program with the US Navy to test wave energy technology, giving the US their the first-ever grid connection for a wave energy device.
Kiyomi Suzuki, president of the Hyogo Prefecture firm Nova Energy Co., has come up with a new interesting project for the Seto Inland Sea that aims to produce huge amount of electricity from the energy of water currents, using streamlined turbines whose design resembles the tuna shape.
Wave Hub is the name of one of the world’s biggest wave energy generation test site. It has been installed off Cornwall’s northern coast and is the UK’s first offshore wave energy site. Wave Hub will allow four wave energy generator systems to be evaluated simultaneously. The systems also have a total capacity of 20 MW.
