📈 Green hydrogen production capacity almost doubled in 2025 to around 4 GW of globally installed electrolysis capacity. That's impressive. However, it still falls far short of the exaggerated announcements from a few years ago. (1/n)

The steel sector is responsible for a huge chunk of global CO2 emissions, eating up 20% of the carbon budget for 1.7°C under current trends. The good news: Most of these emissions can be abated at moderate costs of $100-150/tCO2. Have a look at our new paper out in Nature Climate Change today!
⚙️New paper out in Nature Climate Change! Coal-based steel plants operate for decades, and continued investments in new and existing capacity risk locking in emissions well into the 2060s. But we show that there is still a narrow window to act. 🔗 www.nature.com/articles/s41...

🆕 Cost-effective #climate #mitigation would reduce fossil fuel consumption in the EU by around 90 percent by 2050, compared to 2020. Rapid expansion of renewable energy and widespread electrification are key drivers of this shift, researchers show. ⬇️ www.pik-potsdam.de/en/news/late... #NetZero2050
Since everyone is busy "resetting", here is a more focused plea: let's manage our sustainable biomass better. People get nervous around biomass (it's complicated!) but high costs for green hydrogen and direct air capture mean we need to take a closer look. Blog: nworbmot.org/blog/biomass...
Wasserstoff als Energieträger wird eine große Zukunft haben, aber nicht für motorisierten Individualverkehr. Das steht völlig außer Streit, alle Leute, die sich in dem Bereich auskennen, sagen das seit Jahren. Jetzt Autofirmen zu fördern, damit sie Wasserstoffautos bauen, ist verrückt.
