@timbolord Interesting to see that the UK govt does not expect hydrogen to be used widely for heating, in its core modelling pathway to cutting emissions 78% by 2035
(it does model an alternative "high resource" pathway where hydrogen heat is widespread)
@timbolord A key issue for hydrogen heat is that low-carbon hydrogen isn't expected to be available at scale by the mid-2030s, according to the UK govt
@timbolord Also interesting to see UK govt modelling finding that blue hydrogen is needed, but only in the "short to medium term" before truly zero-carbon supplies become available at large scale and lower cost
Just over a decade ago, then-PM David Cameron was infamously reported to have told aides to "get rid of the green crap" as a "solution to soaring energy prices"…
After Cameron's "get rid of the green crap" frontpage, a series of UK climate rollbacks followed
First, policy changes and funding cuts for home insulation improvements, with annual loft+cavity wall installations now 98% below previous levels
Fossil-fueled chemicals boss Sir Jim Ratcliffe has an anti-EV tirade in today’s Daily Telegraph, littered with outright falsehoods, half-truths and selective facts
Exhibit 1: Far from "coming to a halt", EV demand grew by 25% in Q1 of this year
Let’s take a look shall we?
1/
Exhibit 2: Ratcliffe cherrypicks Germany – where EV subsidies recently ended – to argue that demand is drying up
As already mentioned, global EV sales grew 25% in Q1 of this year, according to the IEA

How about China, Jim? Ah yes, EV sales are up 35% so far this year. But I guess that didn't fit your narrative.
Nor does the UK, I guess, given sales are up 11% in 2024ytd (31% for plug-in hybrids, on which more later)
It seems @mattwridley thinks @Telegraph readers are idiots
Let's run the numbers:
244,000km2 = area of the UK
5-10% = share of UK Matt says would need to be covered with solar to meet electricity demand in June
40MW = solar capacity per km2
500-1,000GW = solar capacity, if covering 5-10% of UK
300% = share of total UK electricity demand that would be generated by 1,000GW of UK solar
650GW = current solar capacity of China, roughly half the global total
<30GW = actual UK summer peak demand
15GW = current solar capacity of UK, of which ~10GW ground mounted
0.1% = current solar land take
70GW = UK govt solar target, because no one thinks we can run the country on solar alone
<1% = future land take
>20% = reduction in UK gas imports if govt solar target is met
Zero = credibility of Matt's article
Sources:
Land requirement for UK solar 40MW per km2 = 6 acres per MW, based on current solar farms; as noted in the article, govt says future farms would need 2-3x less land
Despite all the UK govt rhetoric about "new gas", confirmation today in parliament that govt expects unabated gas to meet ~1% of demand in 2035
Minister @grahamstuart, responding to an urgent Q from @CarolineLucas, described new gas capacity as "back-up…sensible insurance"

In the debate, we also saw the mask slip from former sec of state Jacob Rees-Mogg, who as a govt minister paid lip service to climate action (left) but now admits he wants to "postpone net-zero indefinitely" (right)

Responding to Rees-Mogg – who clearly still doesn't understand why geography matters when it comes to energy, trade, or indeed trade in energy – Stuart "chide[d]" him & said there was a "climate…emergency"
UK emissions in 2023 fell to lowest since 1879, new @CarbonBrief reveals
💷Emissions now 53% below 1990, as GDP up 82%
❤️🔥Drop in 2023 largely unrelated to policy
⛰️Coal now lowest since 1730s (!)
🚗Transport is largest sector, then buildings
⚡️Power now likely emits less than farms🐄
UK emissions in 2023 dropped below 400MtCO2e for the first time since the Victorian era, even falling below the levels seen during the height of Covid-19 lockdowns
