Work begins on worldÂ’s largest tidal power plant

subscribe

Lunar Energy Limited and Korea Midland Power Company Limited KOMIPO, a spin-off of Korea Electric Power Corporation, signed a memorandum of understanding to begin development and construction on the world's largest tidal-power project.

Construction of the $600 million Wando Hoenggan Waterway Tidal Plant is already under way off the southern coast of South Korea and is scheduled for completion in January 2015. Once operational, the facility will supply 300 megawatts MW of renewable energy to the region.

Known for its considerable expertise in underwater engineering and fluid dynamics, Lunar Energy associate Rotech Engineering Limited will provide design optimization and specialist components for the project. Lunar Energy has a worldwide in-perpetuity license to exploit the commercial use of the Rotech Tidal Turbine RTT technology, a design patented in the UK by Rotech.

Under the April 2008 agreement, Hyundai Samho Heavy Industries, a subsidiary of Hyundai Heavy Industries Company Limited, was selected to handle the fabrication and installation of 300 RTTs, each with generating capacities of 1 MW.

Tidal energy is still a relatively unexplored source of renewable energy. Tidal mills have been used since the Middle Ages, but it was not until the 1960s that the first tidal power plant began operating. Though more predictable and stable than wind power, tidal generation was generally curbed because of high costs and limited areas of operation. In recent years, advances in underwater technology and turbines, such as those designed by Rotech, have brought about renewed interest in tidal power generation.

Net-zero roadmap can cut electricity costs by a third in Germany - Wartsila

BERLIN - Germany can achieve significant reductions in emissions and the cost of electricity by phasing out coal in 2030 but must have a clear plan to ramp up renewables and pivot to sustainable fuels in order to achieve net-zero, according to a new whitepaper from Wartsila.

The modelling, published in Wärtsilä new white paper ‘Achieving net-zero power system in Germany by 2040’, compares the current plan to phase out coal by 2030 and gas by 2045 with an accelerated plan, where gas is phased out by 2040. By accelerating the path to net-zero, Germany can unlock a 34% reduction in…
