UK Flagging in Fuel Cell Race

 

Despite helping to pioneer the modern fuel cell, the UK is losing ground in its development compared with other countries, a survey says. The report, by industry sponsored analysts at Fuel Cell Today, finds that only a fraction of fuel-cell-related patents have been lodged by UK companies. Most come from the US, Japan and Germany.

Poor investment by the UK Government is partly to blame, say analysts. The introduction of fuel-cell powered vehicles is seen by many as a key step in one day making significant reductions in emissions. However, it may be some years before the technology is fully developed - and the report says that the UK's role in this process is "uncertain".

David Jollie, one of the report's authors, said: "Development of a completely new engine technology is going to take quite a few years, and a lot of work has got to go on around the area. "If you don't start doing that now, you have the problem of missing the boat."

There is only one fully functioning commercial fuel cell in the UK - providing power at a swimming pool in Woking. This, however, had to be sourced from the US because no UK company could supply it. Research funding available to UK groups is dwarfed by more than a billion dollars pledged for the development of cleaner hydrogen vehicles by President George W Bush this year. "We're not investing enough money and there isn't enough government support for fuel cell development" said Julie Foley of the Institute of Public Policy Research

This is despite the fact that it was British scientists who developed the idea that energy could be extracted by combining hydrogen and oxygen. It was first demonstrated as early as 1839 by Sir William Grove. However, it was in the 1950s that the first practical fuel cell was developed by Cambridge scientist Francis Bacon. It was his work which allowed the US space agency (NASA) to provide electrical power for the Apollo moon lander a decade later.

There remain more than 100 organisations in the UK with an active interest in fuel cells or related technology. A total of approximately 850 people currently work in the UK in fuel-cell-related areas, says the survey. Some research funding comes via the Department of Trade and Industry and the European Union.

Many of the proposed applications for fuel cells are transport-related and the UK Department of Transport also offers funding, as does the Carbon Trust and the Engineering and Physical Sciences Research Council.

Julie Foley, from the Institute of Public Policy Research, said that British firms had the chance to be at the forefront of fuel cell research. However, she said: "At the moment we risk losing out on that opportunity, because we're not investing enough money and there isn't enough government support for fuel cell development."

World Warming in 2002 Near Record

Earth is over one half degree Celsius warmer than it was a century ago

 

Scientists meeting in France say 2002 was the second hottest year on record.

It continued a warming trend that has set records for the last five years. Only 1998 was warmer. The planet is now 0.6 C warmer than in 1900, an increase that scientists attribute to human activity.

Researchers say even a fractional boost in average temperatures has significant consequences for the health of the planet.

The findings appear in The State of the Climate, an annual report from the US National Oceanographic and Atmospheric Administration (Noaa), based on research from eight countries.

It was presented at the first joint meeting here of the leading European and American geoscience societies, the European Geophysical Society (EGS), the European Union of Geosciences (EUG) and the American Geophysical Union (AGU).

While the Earth warmed in 2002, the trend in Antarctica was toward cooler-than-average temperatures, a pattern consistent with global climate change, according to Dr Anne Waple of Noaa.

"The Antarctic is a very different beast," she said. "There is a great big land mass stuck at the South Pole and the circulation around that essentially cuts it off every winter. It has its own weather patterns."

 

The second half of 2002 saw a mild El Nino, the periodic weather phenomenon in the Pacific that disrupts climate patterns thousands of miles away.

While global rainfall was average overall, El Nino contributed to extreme drought in the US, comparable with the Great Dust Bowl of the 1930s, and in Canada, Australia, West Africa and India.

Droughts continued in parts of central America, and central Europe experienced near-record floods.

Tropical storm activity was below normal globally, and in India a failure of the monsoon rains led to the first all-India drought since 1987.

Scientists predict more frequent and extreme weather events because of climate change, but last year's droughts and floods cannot be tied definitively to it, said Dr Waple, as the climate record is not long enough.

"But we are operating in a world that is warmer than it was 100 years ago," she said. "Certainly that baseline climate change plays a role."

The meeting, the EGS-AGU-EUG Joint Assembly, heard details of research on the cause of Europe's catastrophic floods and the lessons learned from them.

Jiri Stehlik of the Czech Hydrometeorological Institute said an unusually sluggish low-pressure system that lingered over central Europe had brought two rounds of intensive rainfall within a week. The second overwhelmed swollen rivers and saturated soils.


In Prague, where two rivers meet, the river discharge peaked at 5,200 cubic metres a second, making it a once-in-500-years flood that devastated the city and nearby villages.

"It was a very fast-happening flood," said Hans Wiesenegger, an Austrian hydrologist from Salzburg, where the river Salzach inundated the city.

"Within 18 hours, we had a peak discharge of 2,300 cubic metres a second. The average is 180 cubic metres."

Although flood forecasting was fairly accurate, scientists were unable to predict how the land and rivers would respond to the rain.

The 2002 floods are still considered rare events and attributed to natural cycles. Dr Waple said: &qu
