This study explores the EU’s 2040 climate target. Analysis of over 300 scenarios shows that an 80–93% emissions cut by 2040 (central estimate 86%) is cost efficient, requiring rapid wind and solar exp...

New steel capacity expansion is critical for the feasibility of climate targets, as plants operate for decades. Researchers estimate that while existing and planned plants could commit large emissions...

Extreme periods of low wind and solar energy ("Dunkelflaute”) drive substantial long-duration electricity storage needs in a renewable European power system. Rapid deployment is required to safeguard…

This scenario study investigates how the EU net-zero target can be reached with varying levels of residual fossil fuels. Reducing fossils by only 90% relies on substantial carbon storage, while a full...

Germany’s energy transition relies on variable renewables and electricity use across sectors, and it needs to accelerate. This Comment argues that consistent policy commitments to proven technologies,...

New official estimate reflects surging construction inflation and contingency costs

Wie wird Deutschland klimaneutral? Das klären wir mit nicht nur einem, sondern gleich zwei führenden Forschern aus dem Kopernikus-Projekt Ariadne: Prof. Dr. Gunnar Luderer vom Potsdam-Institut für…

Nature Communications - Abatement options for hard-to-electrify sectors (e.g., steel, aviation) face uncertainty in future costs and feasibility. This techno-economic analysis shows that despite...

Mitigation scenarios are required to account for societal factors. Fisch-Romito et al. integrate factors related to infrastructure, actors’ decision-making and socio-institutional context into a natio...

Green hydrogen is critical for hard-to-electrify sectors, but faces economic headwinds. Odenweller and Ueckerdt quantify green hydrogen ambition and implementation gaps, showing that meeting expectations will remain challenging and costly.

Scaling up green hydrogen will be difficult if future projects solely depend on expensive subsidies. Policy makers need to implement supportive policies grounded in realistic expectations.

Scaling up green hydrogen will be difficult if future projects solely depend on expensive subsidies. Policy makers need to implement supportive policies grounded in realistic expectations.

A robust political strategy based on realistic expectations for hydrogen production is needed as demand for the gas remains low due to its high costs and other factors, researchers at the Potsdam Institute for Climate Impact Research (PIK) said. More than 60 countries have developed industrial market ramp-up strategies for hydrogen in recent years, but in 2023, less than 10 percent of the originally announced green hydrogen production was realised, according to their latest report.
