TOKYO: As the world rushes to cut carbon emissions, hydrogen fuel cells may offer global telecoms an environmentally friendly solution to power energy-hungry remote networks, experts say.
Emissions from powering networks and IT make up nearly a third of the carbon footprint of telecom companies, Lambrette said, based on a survey of 19 global operators. In Japan, hydrogen enjoys strong government support, including subsidies for technology and infrastructure. Hydrogen-fuelled buses and cars are increasingly common and Toyota is building a prototype city powered by the gas near Mt. Fuji. Many companies see an opportunity.
Reshef declined to identify the Japanese company. It announced in July that Germany's Deutsche Telekom is also testing its fuel cells, and the G5 is in commercial use in 14 countries, including the U.S. and Japan, Reshef said."Our pure hydrogen fuel-cell generators are still at the testing stage, not only for the telecoms sector but also for other industries," a Panasonic spokesperson said.
"There's no doubt fuel cells can work," said Tomas Kåberger, affiliate professor at Chalmers University of Technology."But where does the hydrogen come from? If transported, it would likely increase costs even compared to diesel."
