🚨 Update: What's the state of the green hydrogen market ramp-up?
📄 Today, one year ago, we published "The green hydrogen ambition and implementation gap" in Nature Energy (doi.org/10.1038/s415...). We found that in 2023, only 7% of announced electrolysis capacity was realised on time.

🔥HOT OFF THE PRESS: Why the energy transition is disruptive, non-linear, hard to predict and often faster than expected.
Our paper in Nature Reviews Clean Technology shows how feedback loops create virtuous and vicious cycles that can accelerate or block change. 🧵

🆕 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. ⬇️

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.
