An unusual wave-power system that pumps high-pressure water to an onshore hydroelectric plant recently began feeding electricity into the U.K.’s national transmission system. The 315 kW “Oyster device” is the world’s only functioning hydroelectric wave-powered plant, claims its Edinburgh-based developer, Aquamarine Power Ltd. Slide Show Photo: Aquamarine Power Ltd. The 200-tonne 315-kW wave-power device was installed in Scotland for six months of full-scale demonstration trials.

The $15-billion Papua New Guinea liquefied natural-gas project has secured several new off-take commitments from energy companies across Asia, leading joint-venture senior partner ExxonMobil to announce it will press ahead with the 435-mile pipeline project. It would represent the largest foreign investment in Papua New Guinea to date and, when the project is completed, will deliver an estimated 6.3 million tonnes of liquefied natural gas per year to customers across east Asia. PNG LNG, as the project is known, is a joint venture led by Esso Highlands, a subsidiary of ExxonMobil; Oil Search, Santos; the government of Papua New Guinea;
Designing a custom system to lift and set 2,200-ton and 2,600-ton offshore platforms is notable enough. But Belle Chasse, La.-based Versabar Inc. had to work with three different cultures across nine time zones and sail past real-life pirates to a site 8,500 miles away to make its most recent job successful—all within 10 months.

Operators tested the procedure dockside before executing in 110 ft of open water. Versabar was hired by Al Khafji Joint Operations to use its
Slow responses from plant vendors have impeded generic design assessments (GDA) of two nuclear reactor types vying for the U.K.’s potentially large “new build” program. In an interim report released on Nov. 7, the U.K. Health & Safety Executive (HSE) lists inadequate submissions in support of the Westinghouse AP1000 and Areva’s EPR reactors. “If we are to complete GDA on time, we need the design companies to work with us and provide the high-quality and timely information we need,” says Kevin Allars, HSE’s director of the assessment. HSE is scheduled to complete the GDAs in June 2011 after 42 months
Sacramento Municipal Utility District is leading the national shift to �smart grid� networks with help from a $127-million stimulus grant. Photo: SMUD In June, SMUD hired Greenville, South Carolina-based Utility Partners of America, Inc. for $7.5 million to replace the smattering of 620,000 electromechanical and first-generation solid-state meters with Landis+Gyr smart meters that collect usage information digitally in real time from 50,000 demand-response, control relay access points. The digital meters will allow customers who generate their own energy using solar or wind turbines to act as micro-generators and sell power to the grid. The devices could also improve customer service
The U.S. Energy Dept. on Nov. 23 announced it will award $18 million to 107 small businesses to research, develop and deploy clean-energy technologies. The companies were selected competitively from 950 applicants based on near-term commercialization and job-creation prospects. Funding is from the American Recovery and Reinvestment Act. Firms with successful results are eligible for $60 million in additional grants.
The Dept. of Energy has selected 32 projects to receive a total of $620 million in American Recovery and Reinvestment Act funds to advance and evaluate new technologies to make the nation's electricity grid more effective. The DOE funding will be complemented by more than $1 billion in private-sector matching funds for those projects.

The cause of a massive electrical blackout that darkened large portions of Brazil in early November is still being investigated despite initial reports from the national grid operator that lightning and strong winds affected the transmission grid in southern Brazil. Photo: Germano Luders Itaipu hydro plant, on the border of Paraguay and Brazil, stayed in operation following Nov. 10 storms, officials say. Transmission lines serving the Brazilian grid did not fare as well. At 10:13 p.m. on Nov. 10, the lights went out in Brazil. For almost three hours a massive swath of the South American country, including 18 of
Europe’s largest energy project, Nord Stream, this month received vital approvals from Sweden and Finland when they gave their OKs for the twin underwater pipelines to pass through their exclusive economic zones in the Baltic Sea. + Image Image: Nord Stream AG The natural gas pipeline across the Baltic sea Nord Stream will carry natural gas 1,220 km, from Vyborg, Russia, near St. Petersburg, to Greifsburg, Germany. It will cross the territories of four other nations: Sweden, Finland, Denmark and Poland. Only Russia and Germany still have to approve the project, but that is considered a formality. The 1,220-km offshore
As the U.K. begins to fast-track nuclear power permitting, its safety regulator and those of Finland and France have sent Europe’s main nuclear plant supplier back to the drawing board. Already grappling with construction delays at its first EPR pressurized water reactor project—Finland’s Olkiluoto 3 (OL3) plant—Areva Np., Paris, must now also rethink key safety systems. In an unusual joint move, nuclear safety regulators in the U.K., Finland and France recently revealed safety concerns about the EPR’s control and instrumentation (C&I) systems. Photo: TVO Delays Finland’s Olkiluoto 3 nuclear plant may be started much later than the June 2012 deadline.
