'Hydrogen is tomorrow's biofuel' say scientists

Researchers from the University of Birmingham are creating clean hydrogen from food waste paving the way for a bioenergy alternative for the future.

Currently, Brazil is the world’s most intensive user of bioethanol as an alternative to gasoline for powering transport. There are questions about whether the mass production of bioethanol using sugarcane is sustainable in the long-term. Bioethanol generates carbon dioxide and agricultural waste. However, creating clean hydrogen from waste not only uses that waste but provides a fuel that is emission free and can also be generated sustainably.

Presenting this research at a collaborative bioenergy workshop in São Paulo today, Professor Lynne Macaskie, Professor of Applied Microbiology at the University of Birmingham, said “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. At the moment manufacturers pay to dispose of waste but with our technique they could convert it to clean electricity instead.”
