Hydrogen sector targets production boost

 Energy losses in the production process contribute to making hydrogen produced with renewable energy expensive. Companies and researchers are working to improve the efficiency of electrolyser technology and scale it up, bringing down the green hydrogen price tag at the same time

Double up on land use to maximise resources

 For years, farmers had to decide to stick with their traditional produce or twist and turnover their land for renewables projects. Until recently, it has not been a financially viable option for agriculture and solar panels to live side by side. But new techniques are providing a chance to use increasingly scarce land more efficiently

An efficient transition

 The energy transition is not simply a matter of replacing fossil fuels with zero-carbon alternatives. It will also be marked by a radical change in our relationship with energy and the spread of technologies like heat pumps and electric vehicles that can yield significant efficiency gains even before traditional energy savings measures come into play

The energy transition is at risk by hydrogen’s perceived simplicity

 Low-carbon hydrogen will almost certainly be needed to cut emissions across a range of hard-to-abate sectors. However, if it is used to solve too many problems, it could end up delaying the energy transition and putting urgent decarbonisation plans in jeopardy
