🚨New Paper and Policy Brief🚨

How has green hydrogen developed recently? How much hydrogen is needed for 1.5°C? And what are plausible future pathways?

In a new Nature Energy study, we look at these questions.

Cool new study on rescuing 1.5°C with the REMIND model (or so).
🚨🚨🚨 NEW REPORT ALERT 🚨🚨🚨
@climateanalytics.org has a new report out today that I’m really excited about. It’s all about 1.5ºC...

▶️ Is overshooting 1.5ºC inevitable?
▶️ Can we still get temperatures back below 1.5ºC?
▶️ If so, how?

If you’re interested in our findings, buckle up for a mega thread...

when the FT revealed in January that the cost of building the Sizewell C nuclear plant had risen to around £40bn they all denied it

now we can reveal the actual price tag - to be announced this week - and it is £38bn

@nworbmot.bsky.social is doing really important stuff again, simulating how methanol (instead of hydrogen) could be the fuel to power a system otherwise mainly running on solar, wind and batteries. SUPER interesting paper.

🚨 New Research!

Can heat pumps be cheaper than gas boilers? Our study shows how.

🔹 Cost parity at SCOP 3.3 in UK
🔹 Shifting ⚡levies to taxation lowers costs
🔹 Moving levies to gas even more
🔹 Time-of-use tariffs unlock savings

"What do you think about hydrogen-ready boilers?" I was asked by tagesschau.bsky.social

My response:

"If I have a garage, I can also say it's ‘Ferrari-ready’. I could park a very expensive sports car in there. Hardly anyone does that because it's too expensive."

Cool new study looking at near-optimal solutions for biomass in a future European energy system. Biomass is particularly valuable for providing carbon, less so for energy.

Also some interesting points on IAMs in comparison to detailed energy system models like PyPSA.

📄We examine the value of biomass in the European energy system and its interplay with other technologies under stringent emissions scenarios.

An adjusted strategy is needed to ground green hydrogen expectations in reality - Nature Energy
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.
