Creating clean energy technology
As the world prepares for COP26, we focus on University research tackling climate catastrophe. Today, we meet Professor John Varcoe, who’s helping create the next generation of ionic membranes for clean energy technologies.
John's research champions the emerging technology of hydrogen fuel cells as a clean source of energy
A long-time academic in our Department of Chemistry, John’s current research projects focus on developing materials for sustainable electrochemical technologies – and, as he reports, one research area could eventually provide a carbon negative option.
Hydrogen power
“One area we’re researching is hydrogen fuel cells,” says John. “One of the advantages of these is that they use hydrogen and atmospheric oxygen in a non-combustion process to produce energy, heat and water. It’s a clean energy source that does not emit the 'greenhouse gas' carbon dioxide if the hydrogen is produced from electrolysis of water using renewable electricity.
“We create a polymer membrane to act as a key component of such a fuel cell. The polymers, which are made cheaply in the lab, allow fuel cells to be developed with minimal use of scare precious metals, such as platinum. Our alkaline membrane fuel cell concept facilitates the use of earth-abundant metal catalysts.
“Our projects in this field are in partnership with local company AFC Energy in Dunsfold and Newcastle University.”...
