Fuel Cells Crank Up the Power
Unlike the relatively mature internal combustion technologies, fuel cells are improving in efficiency by about 30% a year, according to McNeill. "It's moving so fast," says Joseph Cargnelli, the vice-president for technology at Toronto fuel-cell concern Hydrogenics (HYGS ). "A fuel-cell engine that we developed a year ago is outdated today due to new materials, more power density, and more robust construction."
Perhaps a Caterpilla ain't so silly..
In what may be a sign of the times, the country's largest diesel-generator maker, Caterpillar (CAT ), signed a deal in late April with Danbury (Conn.)-based FuelCell Energy (FCEL ) to jointly produce fuel-cell generator systems. That's quite a statement from a company that books about $2 billion in diesel generator sales each year. It's also a good omen for an industry that has remained painfully nascent for what seems like far too long.
