"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."
"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"
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)
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)
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
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
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
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" 3/6
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: 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
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
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
UK electricity generation from fossil fuels has more than halved in a decade, falling to 91TWh in 2024 – the lowest level since 1955 and making up the lowest ever share of the total, just 29%
Meanwhile, renewable output has more than doubled, up 122% since 2014 to 143TWh 2/9
The UK has cut gas-fired electricity generation by 13% in a decade – even as it was phasing out coal power – thanks to rising renewable output (mainly wind), along with lower demand + higher imports
UK opened the world's first coal power plant in 1882 on London's Holborn Viaduct (pic)
⛰️ Since then, UK coal plants have burned 4.6bn tonnes of coal, emitting 10.4GtCO2
🌍 That's more CO2 than most countries have ever emitted, from all sources (!)
But the UK was the world's first "coal-fired economy" – and that started long before coal-fired power
🥤Coal fuelled pumps to drain mines to get more coal
📈And as steam engines got more efficient, it got cheaper to use and extract ever more of the fuel, inspiring "Jevons paradox"
