REYKJAVIK, Iceland – A few days after the U.S. Congress approved an $85-billion energy bill late last month that critics decried as loaded with giveaways to the fossil-fuel industry and stingy on renewable resource funding and energy conservation, the largest field test of hydrogen-powered municipal buses was wrapping up across Europe.
The energy bill, the outlines of which were years in the making, contained $125 million for a five-year, fuel-cell bus demonstration program and about $3.5 billion for R&D on fuel-cell technology and hydrogen as a clean fuel source.
Although the U.S. Fuel Cell Council, an industry advocacy group, praised the funding, others believe that by designating such relatively small funding to this technology, Congress has ensured that the United States will lag in the development and application of what some regard as the energy technology and fuel of the future.
Early this month, nations involved in the Clean Urban Transport for Europe project concluded a two-year test of Mercedes Benz fuel-cell buses – 30 total – in 10 European cities.
In Reykjavik, Iceland’s capital city, three buses enjoyed a highly successful run, according to Tim Sasseen, a senior field service engineer with Vancouver, Canada-based Ballard Power Systems. Ballard, which is a world leader in the development of fuel cells, partnered on the buses with DaimlerChrysler, Shell Hydrogen and Icelandic New Energy.
“And drivers in Stockholm said they were not as tired at the end of the day due to vibration,” he added.
For the field test, the CUTE project involved installing fuel cells on modified Citaro buses, which is the standard Mercedes Benz municipal bus platform. Project cities were in Sweden, Portugal, Germany, Luxembourg, Holland and Spain, as well as in London and Reykjavik. The project was also run in Perth, Australia.
Electrolysis-produced hydrogen generates energy to power the buses. Water vapor, the sole emission, escapes through the tailpipe.
Besides being a clean fuel source, fuel cells are two to three times more energy efficient than gasoline, Bragi Arnason, a University of Iceland professor and the nation’s hydrogen guru, noted in the July 8 Grapevine, an English-language newspaper.
So far, DaimlerChrysler is the world’s leader in fuel-cell adaptation to municipal transit. Toyota has eight hybrid/fuel cell buses in Tokyo, according to Sasseen, and a bus project is set to begin this autumn in Beijing.
Last September, the U.S. Department of Energy announced a demonstration program involving Ford Motor Corp. vehicles equipped with Ballard fuel cells.
Besides mass transit and eventual automobile usage, fuel-cell technology is envisioned for a host of energy applications, including home heating and home electricity and even cellular phone power.
Optimistic estimates are that it will be another five years before fuel-cell buses begin to be cost compatible with diesel buses. It is expected to be several more decades before fuel-cell automobiles are in widespread use.
In April 2004, California Gov. Arnold Swarzenegger signed an executive order creating a public/private partnership to build a network of 150-200 hydrogen fueling stations or a “hydrogen highway” by 2010.
Hydrogen for fuel cells can be harvested from various sources, including natural gas, biomass, coal, oil or water. Producing it from those sources typically results in the generation of carbon dioxide at the beginning of the process, which is counterproductive to the clean-energy concept.
However, the hydrogen produced for the Reykjavik buses comes from water – from Iceland’s hydro-electric grid, which is virtually pollution free.
