Hydrogen’s Energy Potential

The Pipeline

Questions swirl around the idea of bioethanol as an alternative to gasoline for powering transport, but researchers from the University of Birmingham have started creating clean hydrogen from food waste, an idea that could revolutionise the bioenergy industry.

A look at Brazil — the world’s most intensive user of bioethanol — finds that mass-producing bioethanol from sugarcane is not as sustainable in the long-term as would be hoped. Bioethanol generates carbon dioxide as well as agricultural waste.

However, creating clean hydrogen from food waste not only uses up that waste, but provides a fuel that is emissions free and can be generated sustainably.

“Fuel cells need clean energy to run them. If you provide bacteria with a supply of sugary waste from, for example, chocolate production, the bacteria can produce hydrogen,” said Professor Lynne Macaskie, Professor of Applied Microbiology at the University of Birmingham, who presented the research at a collaborative bioenergy…
