Ministers set to admit Sizewell C nuclear plant pricetag has soared to £38bn New official estimate reflects surging construction inflation and contingency costs

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."

Although I have to politely disagree with the statement that IAMs don't include e-fuels and DAC. While this was the case in the past and might have led to a bioenergy/BECCS bias, many IAMs include both by now. Tagging @fschreyer.bsky.social, @rpietzcker.bsky.social , @gunnarenergyclima.bsky.social

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.

The green hydrogen ambition and implementation gap - Nature Energy 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.

A new study from @adrianodenweller.bsky.social and @falkoueckerdt.bsky.social quantifies the green hydrogen ambition and implementation gap, finding that meeting expectations will remain challenging and costly. https://bit.ly/40mppIh

🚨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.

Suggestions still welcome, too.

A 100% must-read for everyone that has ANY stakes in hydrogen. Frankly, the H2 ramp-up is not going great right now globally, and Adrian and Falko have the numbers. I think we are reaching a phase of honesty, where we have to turn the popping bubble of over-expectations into something productive.

I think we can agree that we urgently need to get rid of fossil fuel subsidies.

NEW RESEARCH: Green hydrogen production has lagged behind expectations in the past and future ambitions are likely not to be achieved shows new research.
