While the energy transition to decarbonise the EU’s economy fully by 2050 will be felt economically in all member states, the costs of decarbonising can be substantially lowered through maximising the production of hydrogen, which in turn can be used to generate electricity. This column uses a global climate-energy economic model to compare three energy production scenarios. It finds that wind energy plus gasification of biomass, natural gas, or coal with carbon capture storage can reduce the cost of achieving Europe’s 95% emissions-reduction goal by 40%.

Can renewable energy save the world from climate change, and do so at a reasonable cost? This column says we can replace some fossil fuel power with renewable power without a major cost increase, but we cannot hope to replace a major fraction of our fossil power with intermittent power sources such as wind and solar energy unless we can develop energy storage technologies.
