BBC Radio 4 - The Life Scientific, Deborah Greaves on wave power and offshore renewable energy

Jim Al-Khalili speaks to Deborah Greaves about wave energy and her love of the sea

Jim Al-Khalili speaks to ocean engineer Deborah Greaves about growing up by the sea, being inspired to study fluid dynamics, and the challenges and possibilities of wave energy.

If you’ve ever seen the ocean during a storm, you’ll understand the extraordinary power contained in waves. On an island nation like Britain, that power could well be harnessed to produce clean energy; so why have we barely begun to tap this bountiful resource?

Deborah Greaves is trying to change that. As Professor of Ocean Engineering at the University of Plymouth, she combines physical wave tanks with sophisticated computer modelling to test how well wave power devices respond to stormy seas. And as Director of the Supergen ORE Hub, she brings together researchers in offshore renewable energy to imagine a future of widespread, eco-friendly ocean power.

Deborah tells Jim Al-Khalili about growing up in Plymouth fascinated by the sea, and about breaking from the norm in her arts-focused family, to pursue a degree in engineering. But she spent years as a civil engineer building tunnels for the London Underground - and going on expeditions to the Arctic with her husband - before undertaking a PhD at Oxford University, exploring what happens when waves crash into solid structures.

She eventually returned to Plymouth and set up the institute’s Coastal, Ocean and Sediment Transport (COAST) Laboratory - a building with a swimming-pool-sized wave tank for testing new technologies. As Jim hears, these wave devices have an extraordinary diversity of uses - and could help to propel Britain into a greener energy future.

Produced by Phil Sansom.
