Hydrogen bubbles forming on the negative terminal of a battery in a glass of salt water. The process is horrendously inefficient, most of the energy in the battery is wasted. Do not try this at home - if you do this for more than a few seconds, things can get very messy, as the battery package can rapidly corrode and rupture, and spill chemical nasties. The salt contaminated battery is also a fire hazard.

The Guardian Finally Wakes Up to the Climate Friendly Hydrogen Economy Joke

Guest essay by Eric Worrall

The Guardian grudgingly admitting that, unlike fossil fuels, renewable energy cannot be relied upon to produce affordable hydrogen for the foreseeable future. Now if only they would take that thought a little further.

Using hydrogen fuel risks locking in reliance on fossil fuels, researchers warn

Electrification of cars and home boilers best choice to fight the climate crisis, say scientists

Using hydrogen-based fuels for cars and home heating risks locking in a dependency on fossil fuels and failing to tackle the climate crisis, according to a new analysis.

Fuels produced from hydrogen can be used as straight replacements for oil and gas and can be low-carbon, if renewable electricity is used to produce these “e-fuels”. However, the research found that using the electricity directly to power cars and warm houses was far more efficient.

Renewable electricity production is increasing rapidly as costs tumble. But it still makes up a small proportion of all energy used, which is mostly provided by coal, oil and gas. Using the electricity directly is efficient, but requires investment in new types of car and heating systems.

Using the electricity to create hydrogen from water and then using carbon dioxide to manufacture other fuels can produce “drop-in” replacements for fossil fuels. But the new study concludes this cannot work on a large enough scale to tackle the climate emergency in time.

“Hydrogen-based fuels can be a great clean energy carrier, yet their costs and associated risks are also great,” said Falko Ueckerdt, at the Potsdam Institute for Climate Impact Research (PIK) in Germany, who led the research.

“If we cling to combustion technologies and hope to feed them with hydrogen-based fuels, and these turn out to be too costly and scarce, then we will end up burning further oil and gas,” he said. “We should therefore prioritise those precious hydrogen-based fuels for applications for which they are indispensable: long-distance aviation, feedstocks in chemical production and steel production.”

The abstract of the study;

Potential and risks of hydrogen-based e-fuels in climate change mitigation

Falko UeckerdtChristian BauerAlois DirnaichnerJordan EverallRomain Sacchi & Gunnar Luderer 

E-fuels promise to replace fossil fuels with renewable electricity without the demand-side transformations required for a direct electrification. However, e-fuels’ versatility is counterbalanced by their fragile climate effectiveness, high costs and uncertain availability. E-fuel mitigation costs are €800–1,200 per tCO2. Large-scale deployment could reduce costs to €20–270 per tCO2 until 2050, yet it is unlikely that e-fuels will become cheap and abundant early enough. Neglecting demand-side transformations threatens to lock in a fossil-fuel dependency if e-fuels fall short of expectations. Sensible climate policy supports e-fuel deployment while hedging against the risk of their unavailability at large scale. Policies should be guided by a ‘merit order of end uses’ that prioritizes hydrogen and e-fuels for sectors that are inaccessible to direct electrification.

Using electricity to produce hydrogen is easy – just drop two electrodes running a DC current between them into sea water, and collect the hydrogen bubbles from the negative electrode.

But producing hydrogen this way using renewable electricity is impossibly expensive, compared to the cost of producing hydrogen using fossil fuel.

However renewable energy prices are plummeting, right? So to kick start the hydrogen economy, all we have to do is start the transition by producing hydrogen using fossil fuel or nuclear energy, then wait for the falling cost of renewables to drive a free market switch to producing the hydrogen using renewable energy.

The Potsdam study, and this Guardian article, is a grudging admission that this predicted transition to cheaper hydrogen produced using affordable renewable energy is not going to happen for decades, if ever.

No, producing hydrogen with renewables is not expensive. Midday RE production supply, here in Cali on moderate temperature windy and sunny days, exceeds demand. This excess deliverability causes it’s market value to drop below zero. Sunshine and breezes fraudsters use these negative prices as a cost saving by using it to produce hydrogen. The more solar we install, and we’re installing a bunch of it, the cheaper the hydrogen becomes because that negative pricing gets way negative! How’s that for a business model? Some would say, stop adding solar, but you’ll never hear that from a liberal (and there’s not much of anything else out here).

Mr. Worral: I agree, in fact I’d go further- comments here have established that connecting wind/solar to the grid is a big mistake. Maybe MR. Sandberg can persuade his fellow Calis to dedicate wind/solar to make hydrogen, disconnected from the grid. I surmise that wind/solar isn’t fit for that purpose, either, but I would not object to anyone (subsidy free) making hydrogen with free (Ha ah, that hurt) electricity. I also surmise that if Mr. Sandberg were correct “producing hydrogen with renewables not expensive”, then somebody would have done it without all the fuss of tying to the grid. The fact that nobody has done or is doing it tells me wind/solar costs more than the revenue from the H2.

“How’s that for a business model?”
And also, not hydrogen. The demand is for electricity, and is throttled by the capacity of the grid, and is used off the grid by consumers, not for hydrogen production — in case you missed it, the topic. So at peak production conditions and time of day you reach peak. Good. All the rest of the time, someone has got to burn coal and gas to make up.
Add back in the taxpayer subsidy to the cost, I’m sure that it will go back over zero.
But keep on installing pv — the ones you installed last year are down 1% in capacity. Two years ago, down 2%. When was the last time anyone cleaned the surfaces?
How much carbon in that concrete footing? How much lime can be activated for portland cement using only electricity? How much gas does it take to produce a ton of aluminum? Of silicon carbide? Of structural glass?
If the accountants hide the production costs, then operating efficiency looks really, really good. Don’t tell folks the real story, they get mad.

Fusion will never be cheap, as long as tritium is $30,000 a GRAM and the only real supply of Helium3 is on the moon (and that’s even harder to fuse than deuterium and tritium). Hard to beat combined cycle natural gas plants, though molten salt thorium reactors give me a warm fuzzy feeling (insert meme) because of its safety features, high efficiency and it’s ability to filter out wastes, wastes that only need a few hundred instead of a few tens of thousands of years to decay down.

Buy renewable company share for the next 3 years and dump them before the next presidential election cycle.

But hey, suddenly one day when this someone suddenly appears with his ten thousand cans that used to be free there is another someone who needs twenty thousand cans right now!

Even better to put the hydrogen into any usueable form you then have to compress it more than 800 BAR, which takes vast amounts more energy and heat.
It appears this side of the entire stupidity cycle is entirely missed.

The net result is an total energy efficiency of less than the entire virtue signalling hydrogen manufacture process.

All in fact you are doing is a wasteful battery with no thought or consequences like the Tesla car, what to do with the inevitable dead batteries or dead worn out cylinders.

That energy is totally wasted because as the hydrogen cylinder is decompressed the cylinder gets cold, much like a propane cylinder would, so you can’t even use it to heat a vehicle, you will freeze!

H2 storage is the problem that seems to be ignored, along with hydrogen impacts on steel piping and containers. You could liquefy H2 and store it in vacuum insulated vessels at 20 K. It is also possible to store H2 as hydrides. HWT and Daimler Benz built some demonstration buses using HWT hydride storage systems in the 1990s. If this were economical, we would see quite a few H2/hydride busses on the road today.

Most commercial H2 is produced either as a byproduct or by steam reforming natural gas. Both of these sources are more cost effective than electrolysis of water. The entire green hydrogen thesis is an uneconomical canard.

Why do you need electricity, renewable or otherwise, to make hydrogen?

Quote:Water helps iron react with oxygen by breaking up the oxygen molecule. During the initial stages of rusting, iron loses electrons and oxygen gains electrons. Ferrous and ferric ions then react with water to form ferrous hydroxide, ferric hydroxide and hydrogen.

IOW: Just pop some Iron, any old Iron, into some salt (sea) water to make hydrogen.

Did these people never go to any sort of school, or if they did, what sort of school was it exactly?
And it wasn’t one that taught how to use either your own eyes, brain or Search Engines either. So what does go on inside contemporary schools these days?

Another perpetual motion machine comes to mind.
We ‘invest’ fossil fuel and rare minerals to make steel, concrete, glass and plastic to produce windmills and solar panels, as well as the transmission infrastructure needed.
These produce electricity on an uncertain basis, so we need more materials and fossil fuels to produce batteries.
All thse have life of around 20 years, so replacements need to be built, but by this time the law says that renewable must be used to produce them.
Nuclear is a no-no!
And so on ad infinitum.

Yes hydrogen is dangerous and because the H2 molecules are so small, very challenging to contain in a pressurized system. Leak testing for quality assurance purposes is often performed using a mixture of hydrogen and nitrogen that is below the combustible limit for the H2.

The He atom is actually smaller than an H2 molecule. Cryogenic LHY tanks are helium leak checked. I am also a Ch E and have commissioned many new LHY systems.

The primary danger of H2 is that it burns with an almost invisible flame and the flames emit little to no radiant heat. This means that you only feel burning hydrogen when you are in it.

Griff, the current natural gas piping systems would need to be replaced with materials which are not susceptible to either hydrogen blistering or hydrogen embrittlement. All mechanical joints would need to be replaced by welded joints. All electrical components would need to be upgraded to Class 1, Division 1, Group B.

H2 piping systems inside buildings would need to have all mechanical connections inside exhausted cabinets. H2 flame detectors are UV/VIS, not infrared. The safety training would be a monumental task, since you only feel a hydrogen flame when you are in it.

Do owners of unreliable energy sources of energy (e.g. windfarms) bear the cost of restoring the land they occupy to the way it was when their life is over? As I understand it, this is common with coal mines, and I guess this would/should be factored into the price of the coal.

Unreliable energy sources (aka wind and solar) exclude the vast majority of their costs from their price, and further have the additional subsidy of being given “priority” for use vs. (excuse me) REAL energy sources (aka coal, oil, gas, nuclear, hydro). That’s the only reason they appear to be artificially “cheap.”

Including ALL of their costs, in particular the cost of “backup” power plants running inefficiently on “standby” to be ramped up to make up for the unreliable and unpredictable nature, would reveal them to be infinitely more costly than (excuse me) REAL energy sources that are reliable and dispatchable.

Some additional (elementary) stuff to help & clarify the situation:

As the article states, science is about making the best use of resources along with integrity. And the best use is for people. Presenting something that falls short of that is neither science or a benefit. Mistakes will always be made but should not be adopted for people.

Wait until they discover the cost of hydrogen compression.

Or the cost to liquefy hydrogen.

Safety standards are based on science not irrational fear.

Hydrogen will never be used for heating homes or transportation because it very dangerous compared to the alternatives. It detonates.

In some cases, hydrogen is the only choice. It is very expensive to make hydrogen safe.

In nuclear power plants, hydrogen is produced from water during fission. Also there are some inert radioactive fission product gases. I was the responsible system engineer for handling these gas for both BWR and PWR.

You do not want valves leaking. There are valves that get the job done but the are expensive and require periodic maintenance.

Think about this. Tires have a date stamp because rubber has a shelf life. It is not safe to sell a ‘new’ five year old tire. Last year I damaged a 3 yo tire on my motorhome. So I decided to replace both steer tires. I was asked if I wanted to keep the good tire. Sure! I was then offered $100 for the tire that was $300 new.

I truck driver will be happy to wear out the tire.

If you are my neighbor and put solar panels on your roof or a Tesla Charging station in your garage I will think you are stupid but I will not tell you.

If you park a hydrogen fueled car in your driveway, we will be talking. I will show you the picture of a child walking past. The picture that I will be sending to child protective services.

Several times I have people tell me to mind my own business. One mention of CPS, and it is yes sir and no sir.

The headline reads like …
Oreos best choice to fight the climate crisis, say scientists

Wait- there’s a crisis?

Where? The temperature charts don’t show a crisis.

Life has NEVER been better for humanity. Deaths from from climate, oops, weather incidents are nearly zero.

My mechanics can’t stop the 120psi R-134a from leaking out of the tiny A/C system in my car. So, how are they going to prevent thousands of psi of the tiniest atom we know of from turning the garage under the kid’s bedroom into the Hindenberg Disaster??

It is a twisted world when you need “research” to tell you what basic engineering teaches. “However, the research found that using the electricity directly to power cars and warm houses was far more efficient.” Who would have thought?

The Potsdam Institute belong to those who think “combustion technology” = bad. They also think “combustion technology” = old. And they think “fuel cell technology” = good & brand new, as well as anything electric.

Their basic premise here is to get rid of engines for cars, trucks, trains and ships. They tend to think you can electrify anything.
