How much would it cost to ensure electrolytic #hydrogen production is truly low-carbon?
Debates about how to implement rich new clean H2 subsidies in the 🇺🇸🇪🇺🇨🇦🇦🇺, etc. may hinge on the answer.
A new ZERO Lab report compiles the best available evidence:… ImageImage
Earlier this year, ZERO Lab published a peer-reviewed paper showing that three requirements for clean electricity procurement - new supply, deliverability, & hourly matching - are necessary to ensure H2 production meets legal emissions thresholds in IRA… ImageImage
Although these 'Three Pillars' are the only viable way to enable H2 production at the effective emissions rates required by the Inflation Reduction Act, some industry players have argued that compliance would be too costly and would kill the nascent H2 industry in the cradle...

The new UK #hydrogen strategy looks like an exercise in providing ongoing revenue to North Sea operators under the pretence of climate action. It'll impose a huge cost on UK taxpayers and lock us into a high emissions pathway.
Here's why. A short 🧵... Image
To meet the new Low Carbon Hydrogen Standard, GHG emissions intensity must be within 20gCO2/MJ of hydrogen produced (LHV). BUT:

📣 New EU Gas Exit Pathway: EU can halve its #fossilgas use by 2030 & completely phase it out by 2050, with less renewable #hydrogen than planned in #REPowerEU while fully ensuring security of supply, without disruptive behavioral changes. Findings ⬇️ 1/9
An accelerated #fossilgas phase-out is possible through structural demand reductions in #energy, #buildings & #industry➡️ key measures: a quick ramp-up of #renewableenergy, electrification and energy efficiency. 2/9 Image
In the power sector, the fastest way to reduce gas demand is by ramping up wind & solar. Aim: 70% renewables-based power generation by 2030 & 85% by 2040. Deep geothermal & large-scale heat pumps will also help reduce gas demand in district heating generation. 3/9 Image

#Hydrogen, a green energy carrier, is one of the most promising energy sources. However, it is currently mainly produced from depleting #FossilFuels with high #carbon emissions, which has serious -ve effects on the economy and environment. 
1/6 ImageImage
To address this issue, sustainable hydrogen production from bio-energy with #carbon capture and #storage (#HyBECCS) is an ideal technology to reduce global carbon emissions while meeting energy demand.

Today and tomorrow, @G7 #Energy ministers meet in #Japan – a country, often considered a “laggard” on #energytransition. What is 🇯🇵’s energy system like and why is it so reluctant to step up #decarbonisation of its economy? A 🧵 1/19…
The “usual” arguments by the 🇯🇵 government when confronted with lack of both action and ambition on #energytransition:
1. #Japan is resource-poor
2. Japan’s geography limits #renewables build-out
3. Technologies & Innovation will solve the transition

How true are they? 2/19
Japan is indeed poor in some resources, most notably #fossilfuels. Fossil fuel based, its energy system is 88% dependent on #oil, #LNG and #coal imports. It has one of the least self-sufficient energy systems, dependent on #oil & gas from #MiddleEast & #coal from #Australia. 3/19 ImageImage

1/ New research @UniLUT @KeinerDominik… investigates the role of #hydrogen in on- and off-grid residential solar PV prosumer systems as seasonal storage option in cost-optimised micro sector-coupling systems until 2050.
2/ Power, heat, transportation segments are modelled and analysed in 8 scenarios varying the availability of grid connection and cars in the system, compared to a 9th grid-only scenario. Cost-optimised solution found via linear optimisation of #LUTprosume model.
3/ Modelling of small-scale water electrolyser and fuel cell economic input data based on growth rates, learning rates and scaling of size. Capex strongly depends on device capacity and is usually high for small-scale applications.

Yesterday, the EU Council and Parliament reached a provisional agreement on the renewable energy directive.

Here's what it could mean for #hydrogen
The agreement sets a target of 42.5% renewable energy in the EU's overall energy mix by 2030.

The agreement also includes sector-specific targets where the role of #hydrogen becomes more prominent.

This quick analysis is based on the press release:…
For reference, these are the shares of #renewables across sectors in the EU in 2021:

21.8% overall renewables

37.5% renewables in electricity

22.9% renewables in heating and cooling

9.1% renewables in transport

Here is why blending clean #hydrogen into gas grids is such a colossally wasteful thing to do. Basically you go to all the cost, effort, leakage risk, etc of making clean hydrogen, and then do a bunch of low-value things with it. Taxpayers/ratepayers should rise up against this.
I had to add an extra level, H, to account for how idiotic it would be to make clean hydrogen, stick it in the gas grid, and immediately use it to generate power. Even high-temperature industrial heat will only be an E or F when I eventually publish an update to the ladder.
As for the idea that you need blending in order to create an early market for hydrogen - bollox. The UK uses 700,000 tonnes of hydrogen for fertilisers and petrochemicals - all from fossil fuels. There's your early market, it's huge and used to handling hydrogen.

How to say that you intend to build 20 GW of fossil gas-fired power stations without saying that you intend to build 20 GW of fossil gas-fired power stations?

All you have to do is announce that they are "H2 ready", i.e. that they will be able to burn #hydrogen in a future that is not your responsibility but that of your successors.

Of course, if these plants continue to burn fossil gas in 10-20 years, your successors will be the ones to blame, because they won't have implemented all the necessary measures to switch to H2.

Anyway, you won't be in charge anymore so it won't be your problem.

1/9 The economic top-institute @DIW_Berlin in Germany brought out a new study “Expansion #nuclear power without technical and economic basis”.… @CKemfert
A little thread about some unsurprising, but for some maybe remarkable findings. Image
2/9 Unsurprising is the conclusion that #nuclear has priced itself out of the market. Construction costs of current generation III+ would have to be reduced with 2/3 in order to maintain the global 10% market share in power production. But those costs are still increasing.
3/9 #SMRs of the light-water type would need production units of several thousands (per design!) to break even their disadvantage of scale, and that would need global harmonisation of #nuclear regulation. Dreams, dreams…

It will take until 2030 to reign in the current bout of hydrogen mania, embark on a real plan to eliminate the 2.3% of emissions currently caused by 94 Mt/year of grey & black hydrogen, and target its use on a few otherwise hard-to-decarbonise sectors. We are in the foothills. 1/
Let me be quite clear - we will need clean hydrogen. But fantasies of a hydrogen economy, hydrogen society and globally traded hydrogen market need to be abandoned. There will be a global market in ammonia, but mainly for fertilisers, chemicals, shipping fuel and some storage. 2/
Again, to be clear. The issue is not production cost. Learning curves mean green hydrogen will end up cheaper than grey. But nothing will change the physics and thermodynamics of hydrogen: low density; escapey; explodey; embrittley; NOx-producey if burnt; greenhouse gasey. 3/

What were #India’s major hits and misses in #ClimateAction in 2022?


1. As per the requirements of the #ParisAgreement, India submitted its plan for #NetZero #emissions by 2070 and also updated its NDCs.

🔖 Bookmark this #thread!

2. Long-term strategy (updated) + Nationally Determined Contributions (NDCs), which reaffirm attention to #climate policy. #India also consolidated its position on climate #geopolitics globally.

3. #India announced some big policy changes to upgrade for planned #renewables expansion.

The draft new electricity plan increases the 150GW target of installed #solar capacity by an additional 36GW to 186GW by 2027.
