GM to decide on fuel cells in 2010

General Motors will decide in 2010 whether to go into mass production with cars powered by fuel cells running on hydrogen.

There are two targets the automaker has set for itself. The first is to have a fuel cell which will run for 5,500 hours - the equivalent of driving between 116,000km and 240,000 km depending on use. The second is to get the cost down to the equivalent of $50 per kilowatt of power produced. „A small, mass produced petrol engine which we make in the millions costs $30 per kilowatt,” said Lars Peter Thiesen, manager of General Motors Europe's fuel cell deployment strategy. „A big, sophisticated engine with direct injection costs $70 per kilowatt, so we've pitched the fuel cell midway between the two,” he said, speaking at a media briefing at the company's test track near Frankfurt. „I'm very optimistic we can get there - we've invested €1 billion since 1997 and fuel cells are the major part of our global R&D budget.”

Before then, GM will conduct what Thiesen described as a „huge market test around the world” with both ordinary customers and business customers. This will involve having more than 100 hydrogen fuel cell vehicles running to create „a microcosm of car use.” These will be fourth generation FCVs. The first will go into use in the US later this year with the European vehicles ready for early 2008. Until now GM has only built the number of FCVs it needs to learn enough for the next step. Third generation FCVs are currently in use in an industry-wide experiment in Berlin, the Clean Energy Partnership. This also involves Ford, BMW and DaimlerChrysler, with BP and Total providing the hydrogen. A second hydrogen filling station has just opened. One of the major problems is the hydrogen refueling infrastructure, said Thiessen. Although fuel cells could be run on other energy sources, there is no point in using any fuel that isn't itself zero emission. The conversion efficiency of GM's current fuel cell vehicles - the amount of energy extracted from the fuel that ends up powering the wheels - is 36%, well ahead of diesel engines at 22%. „We want to get to 40% or about twice the efficiency of internal combustion engines,” said Thiesen.
