Int'l - Ocean energy production surges tenfold over last decade

Global ocean energy production has risen tenfold over the last decade, according to a report issued today by a leading ocean energy organisation.

Ocean Energy Systems (OES) annual report shows cumulative energy produced from wave and tidal stream sources surged from less than 5GWh in 2009 to 45GWh in 2019.

Numerous other wave and tidal stream devices have been deployed in open-sea waters for testing, while further ‘push and pull’ mechanisms are stimulating the ocean energy sector in various regions of the world.

OES was launched in 2001 as a Technology Collaboration Programme of the International Energy Agency. It was created in response to increased ocean wave and tidal current energy activity primarily in Denmark, Portugal and the UK. The organisation now consists of 25 members including specialists from government departments, national energy agencies, as well as research and scientific bodies.  

OES chairman Henry Jeffrey from the University of Edinburgh said the new report communicates the sizable global effort to identify commercialisation pathways for ocean energy technologies.

“Our latest report underlines the considerable international support for the marine renewable sector as leading global powers attempt to rebalance energy usage and limit global warming. Decarbonisation has been appointed as the main strategy to tackle this challenge and many countries around the world have revised or set ambitious targets for emission reductions while ramping up the electricity production from renewable resources,” said Jeffrey.

He added: “The start of this new decade carries considerable promise for ocean energy. Important projects and deployments are being planned for the coming years as the mission to decarbonise intensifies and governments across the globe show increased interest in ocean energy technologies.”
