Green #Hydrogen Task Force:
Action plan by hydrogen industry, supported by @RockyMtnInst: 👇
- Imported green H2 could be cheaper than domestically produced grey or blue H2 through to 2030
- need of €20 to €30 billion near-term market and first-mover support by 2030
While green H2 is currently competitive with grey and blue H2 produced with natural gas (see Exhibit 4 above), green H2 fuel is still more expensive in direct competition with fuels like natural gas, crude oil, and coal, which it will displace across several sectors.
"The EU ETS price is projected to rise from €80/tonne (2022 average) up to €140/tonne by 2030. Pricing trends that will determine market risk level for green hydrogen are depicted in Exhibit 5."

o -13% energy demand 2030 (vs -9% prior target)
o 45% energy from #renewables 2030 (vs 40%)
o x2 today's #solar by 2028
o Greater use of heat pumps, geothermal & solar thermal
o #Wind build-up to be “drastically accelerated” 1/2
Leaked #RepowerEU draft on #hydrogen:
o 20Mt demand by 2030 (already known)
o 10Mt from EU + 10Mt from non-EU
o Subsidies for EU & non-EU renewable hydrogen
o Three “hydrogen import corridors” via the Mediterranean, North Sea and, eventually, Ukraine 2/2…
Bonus: the three "#hydrogen import corridors" are aligned with the analysis in our report on the Future of Renewable Hydrogen in the EU, in which countries in North Africa, Northern and Eastern Europe were identified as key suppliers for the EU:…

This is a #Gigafactory, #nuclear style. It is a factory that makes modular 600MWt high temp nuclear reactors and high-temp steam electrolysers. First 36 of them (22GWt) will populate the clean hydrogen plant built next to it, producing ~85 TWh (~2.4 Mton) of clean H2 / year.
After the first 36 reactors are built, the factory has likely been amortised, the processes fine-tuned to excellence and production costs for further units are low. They can be shipped to populate other power / hydrogen plants.
We could build one of these in #Finland, next to the envisioned #hydrogen-pipeline to Germany. Such a pipeline needs to be big to make sense. 10 GW is decent size, enough to take most of the H2 produced at Gigafactory 1. We can build pipeline bigger and export #wind H2 as well.

Hydrogen '2x as powerful a greenhouse gas as thought before': UK govt study

Global Warming potential (GWP) of #hydrogen is between 6 & 16, 11 the ave — GWP of CO2 is 1. Previous 2001 study put GWP of hydrogen at 5.8…
“Any leakage of H2 will result in an indirect global warming, offsetting greenhouse gas emission reductions made as a result of a switch from fossil fuel to H2,”

"much smaller molecule than #methane.. much more easily leak from existing #naturalgas pipelines if used to carry H2"
report does not take into account GWP of PRODUCING hydrogen, only impact of H2 released into atmosphere

electrolysis production of H2 wld result in 9.2% leakage frm “venting & purging”, but this wld fall to 0.52% “with full recombination from purging & crossover venting”.

Now might be a good time to spread the good word of #nuclear power amid a #petrol crisis driven by a war that most certainly won’t be the only major war of the 20s or century for that matter.

Nuclear power is not an IF, or MAYBE, it’s a MUST.
Renewables aren’t universally applicable nor are they low on land intensity. Long term solutions in wind and solar aren’t really going to be possible or economically feasible unless you plan to raze thousands of miles to create mega #solar and #wind farms.
#Nuclear is low on land intensity and over time will in a large enough quantity likely outproduce gargantuan and exagerrated wind and solar facilities.

Regardless of your stance on climate change this should be something we all strive for. Nuclear is the best future we have.

1/9 Dedicating #RenewableElectricity to #Hydrogen cannot free the EU from #RussianGas.⚠️ What can, is using renewable electricity efficiently.
📚Read what #REPowerEU gets wrong and how to make it right.
#REPowerEU #RenewableHydrogen #Fitfor55 #REDII
2/9 How we use each TWh of electricity has a huge impact on whether we break free⛓️ from #RussianGas.

Using it in #HeatPumps displaces three times more fossil gas than using it to produce.👇
3/9 #REPowerEU foresees the total installed wind 🌬️& PV ☀️capacity to increase from today’s 360 GW to almost 1000 GW + 80 GW of renewables earmarked for #H2.

This will produce over 1000 TWh of electricity⚡️ per year. That’s the 🇫🇷 & 🇩🇪 demand combined.

Behind the military analysis behind the take of #Zaporizhzhya, there's an unexplored reason: Ukraine as exporter of energy to Germany/Europe.

But also the Project CECH. 🧵

#UkraineRussianWar #UkraineRussiaWar Image
#Hydrogen has been a fascinating source of energy to #Germany since 1874. But after the Hindenburg Tragedy in 1937, Zeppelins were cancelled.

Nowadays, because of the climate change, Europe is working in order to introduce again the hydrogen as a clean source of energy.

Thus, Berlin is promoting the CEHC project, a corridor between #Ukraine and #Germany as "alternative" to #Russia.

ZBF release finally draws closer ( We have been working to get the data/report out & understandable. Here is a short thread with some interesting observations that we made. First, here is a cheat sheet for our scenarios (a wide spread of possibilities)
First, we find that scenarios have huge amounts of #wind & #solar. We also find that deployment rates for these (& #storage) must dramatically increase to reach our goals (with and without novel generation).
This becomes increasingly important for limited technology cases & huge for #storage in terms of energy capacity.

What is the future role of #hydrogen in road transport?
In a new comment in @NatureElectron I argue, that hydrogen is unlikely to play a major
role in sustainable road transport.
A thread on the arguments [1/n]…
1. Cars: Almost all car manufacturers gave up on fuel cell passenger cars as fast charging and cheap batteries make long-distance driving feasible with battery electric vehicles.
2. Road freight is more tricky: Depending on load and daily or annual driving distance, current battery electric trucks cannot cover all road freight transport needs.

1/ On the "energy transition" and geoeconomics:
My experience, including e.g. lobbying for #electrification of #transport before it was cool, is that govts prefer the path of least resistance, which helps the incumbent #oil and #gas industry.
2/ So what you get is a compromise of #green policy goals (lower CO2, but not too fast, plus nuclear exit), slow-exiting of #oil and increase in #gas (good for incumbent industry), promotion of #hydrogen (helps gas industry survive), and of course #Russia.
3/ Liberal economic principles, and foreign policy idealism, are brought in just in time to prevent heavy geoeconomic measures to cut dependence on Russia. And so, Europe will do a slow energy transition with Russia guaranteed major benefits for the next few decades.

🧵A new front in the greenwashing battle has opened: blending #hydrogen into fossil gas infrastructure to achieve nominal emissions reductions

TLDR: it's not a climate solution
The reason why gas distribution companies like @Enbridge are touting blended #hydrogen is not because they want the world to go green, but because it will lock in continued use of their gas pipes

They don't care about the climate, they are actively fighting electrification
We have climate solutions for home cooking & heating: we can electrify our homes - and stop using fossil fuels entirely

Electric appliances are a better option than hydrogen in every way: they're available, cheaper, more energy efficient & provide cleaner air

(1/8) A few thoughts on the current debate about the #EUTaxonomy on sustainable energy finance, especially the classification of #gaspower and #nuclear.
(2/8) #Nuclear power has a very peculiar risk profile. It certainly is climate-friendly, with small life-cycle CO2 emissions (like wind and PV). But its waste problem and nuclear accident risks are unique. Ultimately a value judgement whether or not these eco-risks are acceptable
(3/8) The true risk about #nuclear for climate change mitigation: Its track record of delays and cost overruns. New nuclear power makes for a very risky and costly bet for reaching climate targets. Just look at #Olkiluoto, #Flamanville, #HinkleyPoint. #FalsePromise?

Our take on the @EU_Commission’s second part of the #Fitfor55 package aimed at re-designing the EU’s internal #gasmarket rules and governing a future European #hydrogen pipeline network. 1/12
1️⃣ gas market: The proposed revisions to the internal gas market rules do not address that Europe’s #climatetargets imply a rapidly shrinking market for #fossilgas use already this decade. 2/12
The need to scale down #fossilgas and replacement by #electrification and only partially by non-fossil gases must become the underlying narrative of the gas market rules. Here is why! 3/12

1/25 Our new paper on #MitigationDeterrence effect of Greenhouse Gas Removal #GGR #CDR and how to minimize it is out.

Coauthored with @nilsmarkusson @bankfieldbecky @szersynski @dtyfield, @Lancs_LEC

Full paper #openaccess here in EPE:… @envplane

A 🧵
2/25 Sadly this took a long time to get published … perhaps appropriate for a paper called ‘attractions of delay’ which explains climate procrastination as a predictable outcome of multiple reasons for prevarication. Fortunately the findings are still topical …
3/25 TLDR1: #GGR discourses exemplify how tech promises enable prevarication by being enrolled in scientific, cultural, economic & political processes; many stakeholders share concerns that #MitigationDeterrence is arising from exaggerated expectations of future GGR tech.

Have you ever asked yourself ‘what is the role of #hydrogen in climate neutrality🐢?’ We’ve spent the last 11 months trying to piece together a picture from the wealth of research and analyses out there. Below highlights from our recent publication 12 Insights on Hydrogen?📺1/8
In European 1.5C scenarios, hydrogen and hydrogen-based products are most useful in industry🧑‍🏭and transport ✈️🚢, with a potentially large role in the power sector⚡️. Building heat🏘️sees minimal hydrogen. 2/7 Image
More recent global scenarios confirm industrial importance but see less H2 in transport than EU studies due to lower FCEV 🚗expectations. Power sector is again a wildcard and depends on alternative LDES pathways or nuclear revival. Still minimal role for H2 in building heat. 3/7 Image

🚲🚗🚌🚚⛴️ Vancouver Clean Transportation sector report now out from @Invest_Van. 🥳🥳
(I repped my beloved #hydrogen sector.)
2/ The Big 3 asks:
1. Faster Permitting
2. Industrial Land
3. #hydrogen hub 😎
3/ Crop growth is limited by the least-available resource, like how a barrel's water level is limited by the shortest plank.
Clean Transport growth will also be limited by the least-available resource (industrial land?) We're working on it. 👍

Getting the whole world to #netzero #GHGs rapidly is going to be incredibly difficult. But given how strong and organized the #climateopposition is, we must distinguish #thesignalfromthenoise on which pathways are the most likely to succeed. A 🧵 on how I think about this 1/14
2/ First, we cannot rely on social and lifestyle change governed by new paradigms like degrowth to deliver in time for this #climatedecade. But if the movement delivers small reductions in energy or meat consumption, we need it…
3/ #Technologyandpolicy (and politics) need to do the heavy lifting. Can they deliver? Yes, but to effectively channel our efforts and fight off the opposition, we need to distinguish between main courses, side dishes and poison pills (frequently buried in the side dishes)

We have published an English summary of our hydrogen report:…
Key messages:
Hydrogen is necessary for #climateneutrality, but needs to be used in an efficient manner. Only #greenhydrogen produced from #renewable power can be produced sustainably.
Blue hydrogen is currently discussed as a bridging technology. In our opinion, it is not sustainable due to residual GHG emissions, insufficient short-term #CCS capacity and the risk of #fossil infrastructure lock-in. Therefore, it should not receive public subsidies.
Stringent certification is necessary to minimize the environmental footprint and social issues of hydrogen. This is both true for imports and European production.
An additionality criterion for renewables can ensure that green hydrogen does indeed reduce carbon emissions.

Hydrogen is one lever for #climateneutrality in areas which are challenging to electrify. But where does #H2 research stand currently & what new findings are available? With our new impulse "12 Insights on #Hydrogen" we shed light on the subject. 🧵 👇 1/8 Image
Finding 1: By 2050, carbon-free #H2 provides 1/5 of world's final energy, mainly made from renewable electricity. H2 should first decarbonize industry, shipping, aviation + consolidate a #greenenergy system. H2 infrastructure should meet need of industry, ports & power grids. 2/8 Image
Finding 2: Financing #greenH2 in no-regret applications (industry, power, shipping, aviation) needs additional policy support since #carbonprice will remain insufficient over the next decade. No credible financing strategy for introducing green #H2 in #households. 3/8 Image

#Hydrogen is touted by some as THE great climate remedy.

Parts of the #aviation industry are also telling us that we will soon be flying on hydrogen.

Why this is not true - a thread. 🔽 🧵
The basics: in order to use hydrogen as a power source for aircraft instead of kerosene it could either be burned in a jet engine or used to feed a fuel cell to generate electricity to power a propeller.
Hydrogen is produced from other energy sources, has a significant energy loss during the process and is usually stored in liquid form at −253 °C.

Technology for pollution-free "electric flight" is being evaluated in a number of NASA Glenn Research Center programs. One approach is to drive propulsive fans or propellers with electric motors powered by fuel cells running on hydrogen. 1/5
For large transport aircraft, conventional electric motors are far too heavy to be feasible. However, since #hydrogen fuel would almost surely be carried as #liquid, a propulsive electric motor could be cooled to near liquid hydrogen temperature (-423 °F) 2/5
by using the fuel for cooling before it goes to the fuel cells. Motor windings could be either superconducting or high- purity normal copper or aluminum. The electrical resistance of pure metals can drop to 1/100th or less of their room-temperature resistance at liquid 3/5
