Global marine energy capacity will reach at least 300GW by 2050, according to a new report.

The study predicted marine power could create 680,000 direct jobs by the middle of the century.

If the forecasts are proved correct then the installed capacity would save 500 million tonnes of carbon dioxide emissions.

The report’s authors think the rate of growth of marine energy between 2030 and 2050 will match that experienced by the offshore wind market over the past two decades.

Slow progress so far

The document acknowledged that most ocean energy technology was currently either a prototype or a concept.

It also noted progress over the past 15 years has been slower than was previously forecast.

The report was compiled by Ocean Energy Systems, an intergovernmental organisation operating under the auspices of the International Energy Agency.
