How lobbying works Pt 994

Heat & transport are the "two key sectors which appear to have the strongest potential for hydrogen"

Really?

So says Council for Science & Technology, chaired by @uksciencechief to advise UK PM

And who *really* says that?

1/

assets.publishing.service.gov.uk/government/upl…
The line comes from a letter to @beisgovuk secretary of state @KwasiKwarteng, PM & other senior ministers

The letter is billed as advice on decarbonising homes & the development of a hydrogen economy

It's signed by Patrick Vallance @uksciencechief

2/

assets.publishing.service.gov.uk/government/upl…
But who actually wrote the advice?

"We would like to thank Dervilla Mitchell (Director of Arup) and Paul Stein (Chief Technology Officer, Rolls-Royce plc) for leading the briefing sessions and development of this advice."

3/

assets.publishing.service.gov.uk/government/upl…
Nothing wrong with having sector expertise to help develop tricky technical advice for govt and, after all, they have declared their interests.

Right?

4/

gov.uk/government/pub…
Thing is, both Arup and Rolls Royce have a business interest in hydrogen, more specifically hydrogen for heat and, er, transport

Here's Arup…

"Arup helps pioneering hydrogen houses" etc etc

5/

google.com/search?q=arup+…
And here's Rolls Royce…

"We see an important role for hydrogen in helping to lower emissions; fuelling buses and lorries as well as for energy storage and home heating…We are developing a range of products based on hydrogen"

(you get the picture)

6/

None of this would matter except for the small fact that building heat & (most) road transport are almost universally identified – by @theCCCuk @IEA @MLiebreich etc etc – as among the *lowest value* applications of hydrogen

7/
Here's the @theCCCuk central view from its sixth carbon budget advice, with building heat & surface transport making up a very small share of hydrogen demand in 2050 (cf shipping, industry, power sector etc)

carbonbrief.org/ccc-uk-must-cu…

8/
Here's analysis behind @theCCCuk central view on home heat specifically (HT @heatpolicyrich ) in which none of the mix in 2050 is pure hydrogen boilers (only "hybrid" heat pump + boiler)

9/

theccc.org.uk/publication/de…
And here's @IEA on hydrogen use in transport (basically only for long-distance trucking) and overall – again, mostly not for buildings or transport

10/

carbonbrief.org/iea-renewables…
To conclude, hydrogen is likely to be very important for reaching net-zero – perhaps even vital – but none of the independent experts I've spoken to see heat & road transport – barring long-distance trucking – as priority areas for the fuel

NEW: UK climate advisers now "more optimistic" net-zero goals can be met

🎯Net-zero "possible" + "good for economy"
📉CO2 halved vs 1990
📈More "credible" policies
🚘🏡EV/heat pumps soaring
But…
⚡"Critical" to cut power prices
✈️Flight CO2 "risk"

1/9 Image
For the first time I can remember, the CCC says its progress report is "optimistic" about UK climate goals being hit. Interim chair Prof Piers Forster says he is "more optimistic" than last yr due to last govt's policies starting to deliver + changes since Labour took office

2/9 Image
Another notable change is that the CCC seems to be getting less prescriptive…

CCC has faced (inaccurate) charges that it has, in effect, set govt policy. But it's now being clearer than ever that it only offers advice – and policy is up to govt.

IEA: Oil still on track to peak by 2030; oil for fuel to peak in 2027

"annual growth slows…to just a trickle over the next several years, with a small decline expected in 2030, based on today’s policy settings and market trends"

Here are some of the most striking charts 🧵
1/8 Image
In recent years, global oil demand has been almost entirely driven by growth in China…

…and that party is now over

Equally, US "dominance" of rising oil supply is also a thing of the past
2/8 Image
Since last year, the IEA has raised its oil demand outlook for the US, due to EV rollbacks etc, but it has simultaneously cut its outlook for China by the same amount

So global demand in 2030 is right where the IEA thought it would be last year

Could this be the biggest climate story of the year?

For the first time on record, China's emissions are falling due to clean energy growth, not slow power demand

Full analysis + outlook by Lauri Myllyvirta:


1/7 carbonbrief.org/analysis-clean…Image
In Q1 of 2025, the clean-energy driven drop in power sector CO2 outweighed small increases in other sectors of China's economy, driving a 1.6% fall year-on-year overall


2/7 carbonbrief.org/analysis-clean…Image
The fall in power sector emissions came despite surging electricity demand growth

This is the first time on record that clean energy growth has been sufficient to cut into coal power, without the help of weak power demand

FACTCHECK: Almost all the headlines on Tony Blair / net-zero are *wildly* inaccurate

REALITY:

1️⃣Net-zero is *only way* to stop warming
2️⃣Blair calls for tech to "turbocharge our path to net-zero"
3️⃣He categorically *does not* say "net-zero is doomed to fail"

🧵
1/6 Image
Blair says a "strategy based on either 'phasing out' fossil fuels in the short term or limiting consumption is a strategy doomed to fail"

This is logically & categorically not the same as saying "net-zero is doomed to fail"

(If you can't see why, I can't help you)
2/6 Image
Nor does Blair say "current net-zero policies are doomed"

Because literally no govt in the world has a current net-zero policy to "phase out fossil fuels in the short term or limit consumption"

Instead, world's govts agreed at COP28 to "transition away from fossil fuels"

NEW: Official advisers CCC say UK shld cut emissions 87% by 2040

⚖️Net cost of net-zero 73% less than thought
💷Total cost to 2050 = £108bn (~£4bn/yr, 0.2% GDP)
🏡🚗H’hold energy/fuel bills to fall £1,400
🔌Electrification is key

THREAD + charts



1/10 carbonbrief.org/ccc-reducing-e…Image
Just so we're clear, let's start with why bother

We're seeing record heat – 100% caused by our emissions – and extreme weather, from floods to droughts to heatwaves

IPCC says net-zero is only way to stop this getting worse



2/10 carbonbrief.org/state-of-the-c…Image
There’s also the global energy crisis, which hit UK particularly hard due to reliance on imported gas, crushing household (and govt) finances

UK has spent £140bn on gas since the crisis began (!)

Shift to net-zero would massively reduce exposure to intl fossil fuel prices

THREAD: New UK govt contract with Drax biomass power plant

* 4-yr contract 2027-2031
* £113/MWh (2012 prices – £155 in today's money)
* Output cap of 6TWh (<2% of UK supplies, cf recent yrs 12-15TWh)
* CfD cost ~£500m/yr
* 100% of fuel must be "sustainable", up from 70%
1/5 Image
UK govt says the contract helps security of electricity supplies, but gives Drax a "much more limited role than today" ie it's limited to run at roughly 25% of its max output

This means it's mainly going to be running when it isn't windy


2/5 questions-statements.parliament.uk/written-statem…Image
Drax has had issues with existing 70% sustainable sourcing rule, but as it'll need less than half the fuel it has been buying to date, the new 100% rule looks more achievable

Notably, new contract terms allow govt to reclaim subsidy if rule not met
