Electrification or hydrogen?

Both have distinct roles in the European energy transition

20-Feb-2024 - A key step to achieving climate neutrality in the European Union is to rapidly shift from fossil fuels to electric technologies powered by renewable energies, a new study shows. At the same time, hydrogen produced from electricity will also be indispensable in hard-to-electrify sectors such as ...

Green hydrogen: Short-term scarcity, long-term uncertainty

A breakthrough for green hydrogen is not a given – decisive policy action is required

12-Sep-2022 - Green hydrogen from renewable electricity and derived e-fuels are uniquely valuable for achieving climate neutrality. They can replace fossil fuels in industry or long-distance transport where direct electrification is infeasible. However, even if production capacities grow as fast as wind and ...

Greenhouse gases' millennia-long ocean legacy

07-Aug-2015 - Continuing current carbon dioxide (CO2) emission trends throughout this century and beyond would leave a legacy of heat and acidity in the deep ocean. These changes would linger even if the atmospheric carbon dioxide concentration were to be restored to pre-industrial levels at some point in the ...

EU could afford to lead international climate action

21-Mar-2014 - This week, the heads of the EU member states will meet in Brussels to discuss the adoption of a 40 percent greenhouse gas reduction target for 2030. Despite the fragmented state of global climate policy, such front runner action could reduce future global warming by more than 1 degree if it ...

CO2 removal can lower costs of climate protection

15-Apr-2013 - Directly removing CO2 from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the financial ...
