Confused by "Hydrogen Ready" or "Hydrogen Blend Ready" boilers? Then @HelloHydrogen #HelloHydrogen is working!

Facts: There is no H2/gas blend today and may never be; no boilers are ready for 100% H2. 57% of UK power is renewable or nuclear; heat pumps multiply its impact by ~3
Now #HelloHydrogen are lobbying for blending, which would require £ tens of billions investment in electrolysis or CCS.

Facts: 20% H2 by volume would reduce emissions by 7%, less the impact of pumping load, H2 leaks and, if it's blue H2, methane leaks and incomplete CO2 capture.
#HelloHydrogen @HelloHydrogen want you to believe we have to blend #Hydrogen into the gas grid to create a market for clean hydrogen. Nonsense.

Fact: There's a 94 million tonne, $120 billion, global market for hydrogen today, almost all made from fossil fuels. Clean it first!
If you do go to the brainache of making clean hydrogen, blending it into gas is the worst use for it.

Fact: power generation uses 1/4 of UK gas; renewables->H2->power wastes 70%! Space heating uses half of UK gas; RE->H2->heat is 46% efficient. RE->heat pump is 270% efficient!
The #HelloHydrogen crowd want you to believe you can just "Keep the boiler, change the gas".

Facts: Hydrogen will be at least twice as expensive per unit heat as fossil gas. And a "H2 blend ready" boiler will not remotely prepare your home for 100% H2.

Finally, the #HelloHydrogen crowd have spent years telling you heat pumps require more insulation and new radiators.

Fact: they have also spent years setting up condensing boilers at the wrong flow temp. Almost all houses can be warm at 60C flow temp, ie they are #HeatPumpReady
Really finally: the #HelloHydrogen @HelloHydrogen crowd are desperate not to talk about NOx pollution. All combustion produces NOx, but hydrogen particularly, because of its high flame temp. They want us all producing NOx in our homes. We really just need to stop burning stuff.

Hilarious. Any engineer can tell you hydrogen is not like LNG. 30% energy lost in liquefaction; 38% of the volumetric energy density; 6x the boil-off; embrittles; -253C; etc. Transport cost 2-3x production cost? No more than homeopathic quantities of H2 will ever move by ship.
And if it's ammonia, then they should just call it fertiliser, not hydrogen. There will only ever be homeopathic volumes of ammonia shipped for power generation because power->H2->ammonia->liquid->shipping->power currently has a round trip efficiency of ~15% vs ~85% for HVDC.
Nope, not just ammonia: "The Participants aim to closely collaborate on all aspects necessary to kickstart the hydrogen economy and to create a transatlantic supply chain for hydrogen well before 2030, with first deliveries aiming for 2025." Homeopathy! nrcan.gc.ca/climate-change…

How messed up is this? "Thousands of studies use RCP8.5 as business as usual, and the scenario that is used as policy success is RCP4.5. But today much of the literature considers RCP4.5 as an *upper bound* based on current policies." #RCP85isBollox
youtube.com/clip/Ugkx78bVv…
Here I give a concrete example of RCP8.5 being used as BAU, and RCP4.5 as what success looks like - even though we are now on RCP4.5 or better. From the US National Climate Assessment 2018, which spawned climate porn headlines in NYT and CNN and others.
youtube.com/clip/UgkxAswnF…
Don't believe the US National Climate Assessment 2018 used RCP8.5 as BAU and RCP4.5 as policy success? There it is, plain as day on page 1358: "Annual damages under RCP8.5" and "Damages avoided under RCP4.5". This is #RCP85isBollox and drives bad policy. nca2018.globalchange.gov/downloads/NCA4…

So @RogerPielkeJr says he represents IPCC orthodoxy. Does the IPCC say climate change is causing extreme weather? Yes and no. First, we need to know how the IPCC identifies climate change: detection of changes in weather over 30 years, plus attribution.
youtube.com/clip/UgkxTLIgn…
The IPCC has both detected and attributed the signal of human-caused climate change in some phenomena: heatwaves, extreme precipitation and fire weather; but for floods, droughts, and tornadoes there is "no attribution and little detection." From here:
OK, but what happens when there is a single, really extreme event like the recent India/Pakistan heat wave, floods in Australia, drought in the Horn of Africa, CA fires? These cannot pass the IPCC 30-year test, but are they not evidence of climate change?

This week's guest on @MLCleaningUp was my friend @P_Graichen, Mr #Energiewende, Secretary of State for Economy and Climate Action in Germany. We talked nuclear, renewables, hydrogen and German's response to Ukraine. I pushed him pretty hard, don't miss it!
cleaningup.live/ep88-patrick-g…
It's an incredibly deep interview, and quite explosive in parts. For instance here @P_Graichen explains that the German heating industry needs to increase installations by 4-5 times in 18 months, from 130,000 to 800,000 or 900,000 installations per year. youtube.com/clip/Ugkx7d956…
The entire value chain in solar, in wind, in heat pumps - has to grow three to four-fold. @P_Graichen is telling industry to invest, but sometimes, he says, he is astonished that industry doesn't seem to believe that this is actually going to happen. youtube.com/clip/UgkxV2c5s…

"Crypto Billionaires’ Vast Fortunes Are Destroyed in Weeks" - colour me #Schadenfreude! They got rich pumping a technology that has consumed vast material and human resources, and produced no services of value to humanity so far other than entertainment. bloomberg.com/news/articles/…
Re entertainment: if you see #crypto as mainly a branch of the gambling industry, it all makes sense. Remember the vast poker craze a few years back? People like to gamble - and if they can tell themselves they are changing the world at the same time, expect a big bubble.
Who puts their life savings in a crypto coin? Who borrows from the bank to fund #crypto investments? There are answers I can think of: shrewd investors with bad timing; victims of a scam; gambling addicts; or complete idiots. What do you think?

So, this Mayday we're still on break between Season 5 and Season 6 of @MLCleaningUp. My guest for Episode 1 of Season 6 is an immense figure in climate finance - find out who it is at the end of this thread. Meanwhile, let's recap the top 12 most popular episodes so far... 1/14
In 12th place it's "Green Trade or Green Tradeoff", with former Australian PM Tony Abbott. Not known for supporting climate action, his is an important voice nevertheless. And we agree that trade is essential to reduce the cost of clean solutions. 2/14
cleaningup.live/ep52-tony-abbo…
In 11th place, it's "The Man in Charge of Charging", @PRomano_OG, CEO of @ChargePointnet. Transport is going electric, it's going electric fast, and here's why. 3/14
