Climate change: ‘Bath sponge’ breakthrough could boost cleaner cars

By Matt McGrath
Environment correspondent
18 April 2020

A new material developed, by scientists could give a significant boost to a new generation of hydrogen-powered cars. 

However, hydrogen vehicles suffer from some drawbacks. 

The gas is extremely light – In normal atmospheric pressure, to carry 1kg of hydrogen which might power your car for over 100km, you’d need a tank capable of holding around 11,000 litres.

To get around this problem, the gas is stored at high pressure, around 700 bar, so cars can carry 4-5kg of the gas and travel up to 500km before refilling.

Now researchers believe they have developed an alternative method that would allow the storage of high volumes of hydrogen under much lower pressure. 

The product, with the glamorous name of NU-1501, has been built from organic molecules and metal ions which self-assemble to form highly crystalline, porous frameworks. 

“It’s like a bath sponge but with very ordered cavities,” said Prof Omar Farha, from Northwestern University in the US who led the research.

“With a sponge, if you spill water and you wipe it, in order to reuse the sponge, you squeeze it. 

“With this material we use the same thing – we use pressure to store and release these gas molecules.”

The abstract of the study;

Balancing volumetric and gravimetric uptake in highly porous materials for clean energy

Zhijie Chen1,*, Penghao Li1,*, Ryther Anderson2,*, Xingjie Wang1, Xuan Zhang1, Lee Robison1, Louis R. Redfern1, Shinya Moribe1,3, Timur Islamoglu1, Diego A. Gómez-Gualdrón2, Taner Yildirim4, J. Fraser Stoddart1,5,6, Omar K. Farha1,7,

A huge challenge facing scientists is the development of adsorbent materials that exhibit ultrahigh porosity but maintain balance between gravimetric and volumetric surface areas for the onboard storage of hydrogen and methane gas—alternatives to conventional fossil fuels. Here we report the simulation-motivated synthesis of ultraporous metal–organic frameworks (MOFs) based on metal trinuclear clusters, namely, NU-1501-M (M = Al or Fe). Relative to other ultraporous MOFs, NU-1501-Al exhibits concurrently a high gravimetric Brunauer−Emmett−Teller (BET) area of 7310 m2 g−1 and a volumetric BET area of 2060 m2cm−3 while satisfying the four BET consistency criteria. The high porosity and surface area of this MOF yielded impressive gravimetric and volumetric storage performances for hydrogen and methane: NU-1501-Al surpasses the gravimetric methane storage U.S. Department of Energy target (0.5 g g−1) with an uptake of 0.66 g g−1 [262 cm3 (standard temperature and pressure, STP) cm−3] at 100 bar/270 K and a 5- to 100-bar working capacity of 0.60 g g−1 [238 cm3 (STP) cm−3] at 270 K; it also shows one of the best deliverable hydrogen capacities (14.0 weight %, 46.2 g liter−1) under a combined temperature and pressure swing (77 K/100 bar → 160 K/5 bar).

I don’t see the hydrogen economy happening, just because someone invented a new storage material.

Hydrogen has huge problems. For starters, there is no economically viable path to producing affordable hydrogen from renewables.

The dominant industrial process for producing hydrogen is steam reforming, which requires vast quantities of fossil fuel. Feedstock, usually methane, is heated with steam at such an extreme pressure the water actually combines with the methane; the carbon in the methane grabs the oxygen from the water, producing hydrogen and carbon monoxide. The process is strongly endothermic, so even more fossil fuel is required to heat the reaction chamber.

Renewables can’t even beat this absurdly wasteful process.

There are lots of academics like Australia’s Chief Scientist, who are all excited about the imaginary hydrogen economy of the future, but none of them can explain exactly how to build an economically viable hydrogen economy. Their plan seems to be to throw vast sums of government money at the problem and wait for the magic to happen.

A variation on the theme is to use steam reforming, but sequester the carbon monoxide and carbon dioxide produced by the reaction. The idea is to strip the carbon out of the fossil fuel before it reaches the end user. Although this process is cheaper than absurd ideas involving renewables, it would still dramatically increase the cost of energy, compared to simply burning the unprocessed natural gas directly.

There is also a zero carbon nuclear powered hydrogen production process, but greens mostly like to pretend nuclear power doesn’t exist.

Even if the renewable production cost problems are solved, hydrogen is a terrible gas to keep in confined spaces. Large quantities of hydrogen would be far more hazardous in a home environment than natural gas, heating oil or gasoline. If hydrogen use becomes widespread, it seems likely a lot of people would be injured or killed in hydrogen storage accidents.

It should be pointed out that the Hindenburg burned due to its outer silvery paint layer, which was composed of iron oxide and aluminum powder, also called thermite. Sure, the gas bladders were full of hydrogen because we would not sell Hitler helium, but the ship would have burned quite well anyhow. The sister ship, interestingly, disappeared right after the disaster and appeared a few months later with a brand new exterior. The Germans knew exactly what the problem was. For years we thought the event was our fault, but no, it was not.

LTA (Lighter than Air) vehicles are nice and have their uses, but long range travel is severely limited by altitude restrictions (they cannot cross mountain ranges easily) and mildly harsh weather.
And yes. the doping on the outer skin is what caused the flammability of the Hindenburg.

But, remember that helium, the next lightest element, has twice the mass as as hydrogen. The Hindenburg would need to be twice as big to be equally effective, and engineering does not scale so easily as mass increases as a cube while material strength only increases as a square.

A hydrogen economy won’t be using gaseous hydrogen all that often.
Electrolysis with sea water using all this “abundant green energy” is getting touted:

Actually, no. Hydrogen gas exists as H2 with molecular weight = 2, helium exists as He with MW = 2

In any event the buoyancy is determined by the difference between the density of the gas inside the balloon and the gas outside, which is mostly N2 with MW = 28 and O2 with MW = 32. I still say molecular weight because I went to school in the 1950s and 1960s. I’m supposed to say molecular mass but it just won’t roll off the tongue.

The shell of the ship would have burned quite-well…and taken like 40 hrs, experts and tests show.

Not all thermite is iron oxide-based, nor does all thermite contain aluminum, nor are all iron oxide and aluminum power mixes thermite. And no, it wasn’t thermite.

Apparently the Germans agreed that the culprit was the thermite coating.
The movie of the fire rather explicitly shows the fire starting high up under the top fin and progressing rapidly forward and down. If the covering was not the primary cause, although it was determined that it would be susceptible to ignition from a static charge if a panel became ungrounded, a spark also could have ignited a hydrogen leak. Regardless, the fire still burned primarily on the surface skin.

Reply to  Charles Higley

Even though the initial ignition source may have been the thermite, once it ignited the hydrogen still would have ignited, and the result would have been the same.

Okay, so they have a way to store hydrogen in a sponge for a car, but how about all the handling and storage, let alone the sources, of hydrogen getting from the source to the car? It will have to stored as pressurized gas or cryogenic liquid (more expensive, for sure) and piped or tanked all over the place.

Germany Moves Into Hydrogen With Lessons From OPEC and Russia
Germany is taking its first steps to build an economy based on hydrogen instead of fossil fuels, seeking to deliver both green growth and to avoid being trapped by a small cartel of suppliers.
Ministers have been quietly lining up deals with nations including Nigeria that might produce hydrogen from renewable energy in the near future. The ambition is to reduce Germany’s pollution from on oil and natural gas — and to cut reliance on the counties that produce the fuels.

There was an earlier project to carpet the Northern Sahara with Solar panels, and transport the Power to Europe. Believe it was called Desertec. Despite challenges, that would be more technically advantageous than generating Hydrogen in Nigeria, and transporting Hydrogen to Europe

A little spot of history:

In February 1965 President Charles de Gaulle announced his intention to exchange its U.S. dollar reserves for gold at the official exchange rate. He sent the French Navy across the Atlantic to pick up the French reserve of gold and was followed by several countries. As it resulted in considerably reducing U.S. gold stock and U.S. economic influence, it led U.S. President Richard Nixon to end unilaterally the convertibility of the dollar to gold on August 15, 1971 (the “Nixon Shock”). This was meant to be a temporary measure but the dollar became permanently a floating fiat money and in October 1976, the U.S. government officially changed the definition of the dollar; references to gold were removed from statutes.[3][4]

Hydrogen walks through walls. Even thick steel tanks, which it eat if they are made from mild steel. It is incredibly dangerous when let loose. It has a flame velocity that makes it a difficult engine fuel. It tends to blow the top off things.

Hydrogen burns 10 times faster than diesel so putting it into a diesel engine will wreck the already heavily loaded bearings. it is common for the wrist pin of a diesel engine to be 80% of the diameter of the piston. How will it be made large enough to cope with hydrogen?

The thermal efficiency of an internal combustion engine burning hydrogen is about 25%. A big drop. The case is still not convincing.

I prefer to combine two hydrogen atoms with one oxygen atom. Of course, this has its own problems. For instance, my dihydrogen monoxide mixture is known to cause asphyxiation and death when inhaled, even accidently. Drinking large quantities of it causes death. It scalds the skin at certain temperatures, but at room temperature it deforms the skin. Dihydrogen monoxide is also a key component in fracking and nuclear power plants. It is a greenhouse gas. It causes soil erosion. Still, despite all these problems, dihydrogen monoxide is my favorite chemical.

I have worked with high pressure gaseous hydrogen, liquid hydrogen systems and hydride storage systems. I have given hydrogen safety talks to employees,
customers and at public hearings.

Hydrogen flames are faintly visible at night, but during the day hydrogen flames are only “visible” by the heat strirations they produce. The reason for this is that burning hydrogen produces light in the UV and far blue end of the spectrum. Unlike other burning things (paper, wood, oil, etc.) there is almost no radiant heat from a hydrogen flame. Not only do you not see the flame, you can’t feel it. You can feel the heat once you are in the flame, but there is no warning like the radiant heat from a wood or oil fire.

Another major safety issue with hydrogen is that it will accumulate in the high spots in a room or building. If there is no vent at that location, it has the unpleasant habit of lifting the roof. The ignition energy for hydrogen in air is extremely low and the flammable range is quite wide.

April 18, 2020 11:35 pm

The one method that keeps (almost) popping up is using catalysts to create hydrogen from water through sunlight.

One company (HyperSolar) claims to have made some progress, but the catalyst is still the sticking point, apparently.

Others are working on it, too, but it always seems to make it to the press release stage and not much further.

Catalysts do not reduce the amount of energy required to separate the hydrogen from whatever it is combined with. What they do is reduce the activation energy to allow the reaction to start.

p.s. Why is the Hindenburg incident always used as an example of the dangers of Hydrogen? The problem the Hindenburg had was the cellulose nitrate dope mixed with aluminium powder.

The numbers actually mean that to the weight of a tank certified to operate at 100 bars of hydrogen one has to add the weight of a substance able to hold a bit more than it’s own mass of fuel.

Which would offset each hour of cruise by at least 6’000 pounds of “spongy stuff” dead weight plus the weight of the container and some sort of unknown to me fuel management system.

Which, combined to contingency/extra/reserve fuel weight would annihilate ETOPS and render only regional flights within the capabilities of twin-jets.

Only aircraft with 3 or more engines would be allowed on longer transoceanic routes until they come with a way to cheat laws of physics.

However this would increase our quality of service statistics since given the extra weight we won’t be able to embark passengers, leading to no filed complaints even if we cancel flights all together.

Which increases the surface of the A/C and leads to higher drag, hence more dynamic losses.

It’s not gonna’ go ka-BOOM!!! Most likely scenario is a fire that will burn itself out in relatively short order. Stripping the H2 from the sponge is probably an endothermic reaction, so the fire would help that process along. If there wasn’t a fire, the H2 would slowly leak out and dissipate.

But this is just another toke on the dream-pipe of a Hydrogen Economy. The biggest and most insurmountable obstacle is the hugely expensive infrastructure and logistics of safely delivering huge quantities of H2 from its point of production to its point of end-use.

What I have read is that hydrogen atoms are the most abundant atoms there are. They’re everywhere. Unfortunately, they’re attached to other atoms, and it takes prohibitively large quantities of energy to pry them loose. They’re like dollars: Abundant and ubiquitous, but always attached to somebody else, from whom you can detach them only with great effort.

This idea is crazy. Liquid hydrogen is the most dense way that it can be stored, not in a sponge. A sponge holds liquid water, but the held volume is less than the sponge volume. Hydrogen gas could be stored this way, and probably fairly safely, but a huge volume is still required to store the quantities for transport at low pressure. What is needed is a chemical which bonds with hydrogen easily to form a solid or perhaps liquid, but holds a huge volume of hydrogen in the process, and the reaction is easily reversible. This is not a sponge, foam, gel etc. and is probably slightly fanciful as to its properties. Hydrocarbons are very convenient in this respect, although a lot of the energy comes from the hated carbon!

There is no such thing as a hydrino. Brilliant Light Power, nee HydroCatalysis Inc, then Black Light Power, is an investor fraud and has never produced so much as a single joule of useful energy in its almost thirty ears of existence. It never will, just as fellow fraudster Rossi never will with his fraud.

And while on the subject of fraud I should mention that the fraudster Shawyer has never produced a dyne of thrust with his Emdrive fraud, and also never will.

Hydrogen – STILL not an “energy source”.

STILL being ignored (on account of well-entrenched, Pavlovian-like ‘discipline’ in physics via Bob Park’s diatribes still found online) – the latest validation report involving the the hydrogen (via water decomposition) to hydrino transition or conversion (which IS the basis for an “energy source”):

Dr. Mark Nansteel, Ph.D. University of California, Berkeley (a heat transfer expert) validated up to 275 kW of power produced by BrLP’s proprietary hydrino plasma reaction maintained in its SunCell® using water bath calorimetry. This report includes the description of the test apparatus and test procedure, a detailed systematic development of the proper forms of energy conservation to be applied in the calorimetric measurement, analysis of the heat losses in the tests, and analysis of the thermal and electrical data to obtain the calorimetric measurement of plasma energy release.

And yet somehow, after all these years, nobody is allowed to independently verify the results, even if they agree to sign an NDA, apparently. If it worked, they’d be able to get any number of subject-matter-experts verifying the results, and it wouldn’t cost much, assuming they have a reliable prototype. But only one?

Once again we get an article on hydrogen headed with a scary pic: the author must be moonlighting from the Guardian or similar alarm-peddling rag.

People we can handle hydrogen! We,ve been doing so since Victorian times.

Before the widespread adoption of natural gas many countries ran their heating, cooking, etc on town gas which was approx 50% hydrogen. There was a gas works in most towns: us older folk can remember gas holders being a feature of most skylines. The prime danger was not fire or explosion, it was poisoning due to the 20% CO content of the gas.

There are hydrogen pipelines running across NW Europe which have been there for many decades. I expect there are similar ones around petrochem complexes in many countries. Nobody knows they are there.

As other have said, hydrogen is a non-starter for many practical and economic reasons.
Please let’s drop the scaremongering.

While the general consensus of replies says hydrogen as auto-fuel is too dangerous, too expensive, etc. it should not be forgotten that some of the major auto manufacturers either already have hydrogen fuel cell powered cars, e.g Toyota Mirai and Hyundai Nexo, or have planned launches of the same over the next two or three years, like Mercedes, BMW, PSA (Peugeot) and Jaguar Land Rover just off the top of my head.

Not according to Toyota, they claim the Mirai Mk3 due out this year will be no more expensive to produce than a hybrid and this is before opportunities of scale kick in. Assuming the cars actually sell, of course. There are hydrogen filling stations around, 40 or so in California, 12 in the whole of the UK so very much early days. That said, with so many big names getting serious one might think they have been given a regulator’s nod and wink.

As to running costs, the British Evening Standard used a Mirai Mk1 in long term testing two to three years ago and found the cost per mile to be 17.4p, equitable with a similar performance/standard petrol driven car which came out at 16.3p. especially as the Mk1 was a proof of concept and improvements in efficiency are likely to have accrued.

I don’t say they will ever be more than a niche market or even get taken up by the public at all, but there is no reason to say they will be hopelessly uneconomic. You might be surprised to learn that there are currently 10 double-decker hydrogen powered buses operating in London UK at this very moment.

Not hopelessly uneconomic is it? So how much of the 111.4p/l (USD5.27/ US gallon) average cost of fuel in the UK is tax?

Let’s estimate that assuming that the wholesale price in the US (excluding California) is $1.13-1.64/gal depending on the region. Take the highest price of $1.64/gal and subtract from the $5.27/gal UK average retail price. That’s $3.63/gal in taxes. (70%)

You did plan to levy the same equivalent tax per km driven on hydrogen, right? Is the fuel tax not intended to defer the cost of road maintenance?

Oh wait, since you say that the relative cost of (petrol with tax) to (hydrogen without tax) is 17.4/16.3, then the simple solution is to increase the tax on petrol until hydrogen is cheaper than petrol, wouldn’t that be Modern Econ 101?

Raise the tax on petrol even more and the savings from switching to hydrogen could fund the NHS for years to come, am I right?

Surely none of those companies are receiving government subsidy payments for their virtue-signaling public relations schemes.

It’s just ridiculous for anyone to imply that big auto companies would accept government money to profitably produce prototypes that they know cannot be practically deployed.

Other than being dangerous, impractical, not cost-competitive, and a fraud reliant on subsidy money, it seems like a great idea, Peter. Do tell us more.

The U.K. government announced £28 million ($36.47 million) in funding on Tuesday Feb 18 2020 for five projects focused on hydrogen production.

The funding is part of a £90 million package which in turn comes from a £500 million innovation fund. The Hydrogen Supply program, as it’s known, will focus on five “demonstration phase” projects. Following on from £23million hydrogen infrastructure funding in 2017, £9 million in 2018 and £14 million in 2019

The Advanced Propulsion Centre (APC), formed in 2013 from a commitment between the government and automotive industry through the Automotive Council to position the UK as a global centre of excellence for low carbon powertrain development and production, supports the UK Government’s drive to achieve net zero carbon by 2050. Late last year they funded a programme that integrates Intelligent Energy’s latest generation high powered hydrogen fuel cell system into SUVs for Changan, China’s 4th largest car manufacturer, and buses for ADL, the UK’s leading bus manufacturer.

Also August 15 last year the U.S. Department of Energy (DOE) announced approximately $40 million in FY 2019 funding for 29 projects to advance the H2@Scale concept. The focus of H2@Scale is to enable affordable and reliable large-scale hydrogen generation, transport, storage, and utilization in the United States across multiple sectors. Funded through the DOE’s Office of Energy Efficiency and Renewable Energy (EERE), with contribution from DOE’s Office of Nuclear Energy, the selected projects will advance hydrogen storage and infrastructure technologies and identify innovative concepts for hydrogen production and utilization including grid resiliency.

You still think the UK and other Governments aren’t keen to see hydrogen fueled vehicles Rich? If you want a bigger picture just Google ‘UK hydrogen fuel’ or similar and you will likely be shocked by just how much the concept is being pushed.

It seems that you are completely immune to reason Peter.

You completely ignored everything I asked you and proceeded to demonstrate exactly my point, that your government is exceedingly keen to pour money down any number of rat holes pursuing outrageously uneconomic and utterly unnecessary schemes.

You didn’t mention how road maintenance should be financed once there is no tax on transportation fuel (when the only fuel is subsidized hydrogen).

You didn’t explain how any of these loss-making schemes are going to produce hydrogen without hydrocarbon feedstocks.

And I didn’t even bother to ask you to justify why the UK ought to beggar itself to eliminate CO2 emissions that will be immediately replaced by emissions from China and India within a year after the UK goes carbon zero.

Perhaps it eludes you that I never said that hydrogen fuel cells and distribution systems are not technically possible, given enough OPM and a daft enough government willing to destroy its own society for no reason whatsoever.

I said that the scheme is “dangerous, impractical, not cost-competitive, and a fraud reliant on subsidy money”. You countered with “not so. Look at all the subsidy money being flushed down the toilet. You see, the UK government really is that daft!”

All of my responses can easily be checked via a simple internet search, it is all in the MSM. Personally I think that was a perfectly reasonable response.

As of today the department for transport have given powers to local authoritys to close UK roads if the local authority s deem it suitable, this was after local authorities had been breaking the law by closing roads , on the understanding these measures will be lifted after the pandemic is over.

New UK planning laws are already in operation to decrease personal car transport, eg restricted parking on new estates ,local towns having reduced parking spaces, prioritising electric car parking ,( which wont be affordable for the general population) the UK is hell bent on destroying private mobility, there has been no public consultation on the above measures just the old excuse “we have consulted with stakeholders” even when restrictions are lifted there is talk of no private transport unless you have been tested , second home owners in rural areas will be stopped from travelling to second homes which is the case now, the new legislation will give powers to local authorities to remove you from your second home if you make it there, which they cant do at the moment. All ready in the UK certain roads have been closed for years ,particularly mountain roads ,rural roads.

These measures have been in the pipeline a long time ,covid19 is giving the toltairians a boost to their plans.

The below article is linking the pandemic with air pollution again its suggestive with no dates ect , more scaremongering by the BBC.

Issues with hydrogen:

Whilst it’s light it is very very bulky. You need very big tanks.
Because the molecules are tiny its hard to seal its tanks.
It’s extremely explosive. It may not have the detonation of a proper high explosive but flame propagation is damned rapid in air. The flame is colourless.
Adsorbing it onto a metal foam may keep it in place better but at the expense of even more tank and considerable weight.
Conversion efficiency to and from mechanical power is not good.
It is not a primary energy source.
So: expensive, bulky and/or heavy, dangerous and inefficient.
No wonder greens call it the energy of the future 🙂

“The dominant industrial process for producing hydrogen is steam reforming, which requires vast quantities of fossil fuel. Feedstock, usually methane, is heated with steam at such an extreme pressure the water actually combines with the methane; the carbon in the methane grabs the oxygen from the water, producing hydrogen and carbon monoxide. The process is strongly endothermic, so even more fossil fuel is required to heat the reaction chamber.”

And that is exactly why, today, it won’t work. And yet, people *STILL* believe it is the future.

Nuclear Power has to run full out to be efficient and some of the TVA nuclear plants have pumped hydro storage to balance generating capacity with demand. I suspect you could use excess capacity at low demand times to make hydrogen. The sponge storage could potentially be used to extend the range of EV’s and the article also mentioned methane storage which could make natural gas vehicles more practical.

How about the electrolysis of water? The problem is, that in order to get hydrogen out of water requires at least the amount of energy released when the hydrogen combines with oxygen to make the original water. The second law of thermodynamics says that there will be an energy loss, i.e. it will take more energy to separate the hydrogen from the oxygen in the water than the original heat of formation of the water being decomposed. Far more efficient to use the electricity directly. Anyway, isn’t water vapour a greenhouse gas? Any device powered by hydrogen will have to condense the water vapour produced by the burning of the hydrogen. Fuel cells? Even more energy loss, you’ll end up with even less electricity than you started with. Oh, but of course
with renewable sources we’ll have indefinite amounts of energy to waste. Blah blah etc.

Germany has more wind and solar power than it can economically distribute and utilize. To perpetuate their “Energiewende” dream they need to put windy and sunning excess wind and solar generation to use. No way in hell will they import hydrogen from Nigeria…that BS will disappear during an early draft of “the plan”. They know battery storage and pumped storage is unworkable so hydrogen wins by default. Conservatives, such as the AfD, understand that the only feasible alternative to imported Russian natural gas is restarting their nukes.
