Alstom – Peter Fairley

An industrial research consortium that is a who’s-who of the European power industry says development of technologies to produce high-voltage DC (HVDC) supergrids accelerated in 2012 — “surpassing expectations.” The assessment comes in the supergrids technology roadmap updated earlier this month by Friends of the Supergrid, whose members include power equipment suppliers such as Siemens, ABB and Alstom, as well as transmission system operators and renewable energy developers.

Summarizing the conclusions of an expert group within the International Council on Large Electric Systems — better known as CIGRE, its French acroynm — the Friends of the Supergrid says there is now no doubt as to the feasibility of HVDC networks ferrying renewable energy resources from wherever they are in surplus to wherever they are needed: “CIGRE Working Group B4–52 considered this question, specifically whether it was technically and economically feasible to build a DC Grid, and the answer was yes.” Continue reading “Supergrid Technology Beats Expectations”

Call it a sign of the times: Air France-KLM, Europe’s leading air carrier, is going electric.

Forget about visions of battery-electric airplanes. EV technology has its work cut out just commercializing battery-electric cars, let alone trying to catapult hundreds of passengers into the air. Instead, Air France is recognizing the energy-efficiency and convenience of commuter trains and hitting the rails.

Last week the Paris-based airline launched a joint venture with European bus and train operator Veolia to offer high-speed rail service between London, Paris and Amsterdam beginning in 2010 — the year that EU laws will open international rail travel to competition. For technology they are eyeing a new generation of high-speed coaches that’s nearing completion: the Automotrice à Grande Vitesse or AGV under development by France’s Alstom.

The AGV is faster, more efficient and can haul more passengers than its predecessor, the TGV. In speed tests in 2007 the AGV hit 574.8 kilometers per hour — within spitting distance of the speed record set by Japan’s maglevs. Alstom expects the AGV to cruise at 360 kph in regular service — about 40 kph above the TGV’s limit.

Italy’s NTV is building rails for the first AGV’s, which are expected to begin rolling there in 2011.
