Re: Hydrogen Production Moving to Mainstream Green solution

Time to board the hydrogen bus, says CSIRO. The report claims that hydrogen fuel will play a key role in the future of transport, and highlights places for governments and industry to focus their efforts.

Australia needs to embrace hydrogen transport infrastructure, according to a new report by the CSIRO.

The report claims that hydrogen fuel will play a key role in the future of transport, and highlights places for governments and industry to focus their efforts.

Re: Hydrogen Production Moving to Mainstream Green solution

The article at the link below contains "forward looking" projections...

https://www.yahoo.com/finance/news/reac … 00528.html

The reason I decided to post the link is that the company in focus appears to be harvesting "free" energy in a clever way .... Aluminum requires a significant investment of energy in order to prepare it for use in products.  As I interpret the article, this company collects used Aluminum that is on it's way to being recycled, and uses the aluminum in an exothermic reaction that produces aluminum oxide. The clever use of this resource gives the company an economic benefit, and it yields a product (aluminum oxide) that is available for input to the aluminum industry, at a cost much less that mined aluminum from bauxite.

Re: Hydrogen Production Moving to Mainstream Green solution

Can China make Hydrogen Electrolyzers cheap as it did for Solar? If it can, hydrogen can replace natural gas, another huge win against climate change.

The answer is 'No', even if they can reduce the cost of electrolysis stacks.  Natural gas is something we extract from the ground.  The energy is almost free.  Hydrogen is something that we must manufacture using expensive electricity.   It could substitute natural gas in limited applications.  But it will never replace all of the functions performed by natural gas.  Most likely, we will eventually rely on it as a feedstock rather than as a direct energy source.

Re: Hydrogen Production Moving to Mainstream Green solution

The answer to Post #53 is most certainly "YES" ...

The key is to use solar power to make hydrogen without using a single molecule of the stored energy Calliban reminds us was stored long ago from solar energy captured in plants, and squeezed by gravity and thermonuclear churning of the Earth's mass.

All that stored energy has given the human race a running start in developing the technology needed for life off planet.  There are no comparable stored chemical energy sources elsewhere in the solar system.  Humans need to learn how to stop living off the egg we've been given.

Fortunately, we have 8 billion people, and of that number, a few are working on developing the technologies we need to live comfortably without drawing upon the chemical stores we've been exploiting.

Re: Hydrogen Production Moving to Mainstream Green solution

In another topic, Void recently posted a link to a report on research to improve the efficiency of water splitting to make hydrogen (and oxygen).

http://newmars.com/forums/viewtopic.php … 55#p228255

The method improves performance 200 times (according to the report).  That number deserves study.

The method involves quantum physics used to improve electron transitions to allow the bonds between hydrogen and oxygen to let go.

The method currently (in late 2024) requires the use of rare earth materials, but the researchers will continue looking for more common elements to implement their technique, now that they know it works.

The claim of 200 times improvement seems suspect to me, so I'm hoping a NewMars member will investigate to see where that number comes from .

Re: Hydrogen Production Moving to Mainstream Green solution

For kbd512 re #57

Your conclusion may well be right, but you did not show your work.  Therefore, your post is essentially useless for a reader wanting to learn more about this incredible (ie, unbelievable) claim.

I decided to take analysis step by step...

First, the article cites the Max Planck Institute .... it turns out there are several of them, all associated with the Max Planck Society.

Per Google, I get the impression the Max Planck Society exists and it appears to have several Institutes:

AI Overview
Learn more
The Max Planck Society is a German-funded, non-governmental organization that operates over 80 research institutes around the world:
Max Planck Institutes

These research institutions are organized into five categories based on their research area:
Astronomy & Astrophysics
Biology & Medicine
Material & Technology
Environment & Climate
Humanities
Max Planck Centers

These research institutions are located in partnership with other universities, such as:
Princeton University in the USA
Paris University Science Po in France
University College London in UK
University of Tokyo in Japan

The Max Planck Society was founded in 1911 as the Kaiser Wilhelm Society, and was renamed in 1948 after its former president, Max Planck. The society is known for its basic research in the natural sciences, life sciences, and humanities. Some of the topics that Max Planck Institutes research include: Climate change, The human brain, and Human mobility.

Here are some examples of Max Planck Institutes:
Max Planck Institute for Human Development
Located in Berlin, this institute studies human development, education, and human-machine interaction.

Max Planck Institute for the History of Science (MPIWG)
Located in Berlin, this institute studies the history of science and how scientific thinking and practice have evolved.

Max Planck Institute for Psycholinguistics
This institute studies language and communication, including how children and adults acquire language, how the brain processes language, and how language is related to cognition and culture.

Max Planck Florida Institute for Neuroscience (MPFI)
Located in Palm Beach County, South Florida, this institute provides a collaborative environment for scientists to conduct research.

I attempted to follow up on the author of the article, because at this point I am beginning to suspect that the reporter made hash of the reports coming out of the research. 

Mrigakshi Dixit is the name associated with the article.

Re: Hydrogen Production Moving to Mainstream Green solution

Okay, I'll provide a little more background.  When you shine light of certain wavelengths on topological chiral (handedness) crystals, such as IR, they produce electricity, or directional current flow, somewhat similar to how a photoelectric cell works, but an entirely different operating principle.  Regular photovoltaics work on exploitation of semi-conductor bandgap to induce directional current flow.  A topological chiral crystal substance would work more along the lines of, this handed structure arranges the atoms in such a way that shining light on a more or less homogeneous substance with a particular crystalline structural arrangement does what multiple layers of different materials do.

Some of the more outlandish claims made, such as "massless electrons" and whatnot, I cannot speak to.  Claims such as that are sciency-sounding gibberish to me, equivalent to, "I don't know how to actually explain the odd results I'm looking at, so I'm going to label it an example of XYZ theory, without having to actually prove what's happening in an unambiguous way".  Stating that this new doped chiral crystal catalyst material used to split water is 200 times more efficient than something else, without specifying what that "something else" actually was, nor what all energy inputs and outputs from a process entail, doesn't tell anyone anything useful at all.

It could very well be the case that the topological chiral crystal speeds up the reactivity rate by 200X over Platinum-doped mesh materials, but that doesn't tell me anything whatsoever about how much input energy went into this reaction vs how much Hydrogen came out.  It only tells me that the crystal is 200X faster water-splitter than electricity run through a Copper or stainless steel mesh doped with Platinum.

If, however, we're claiming that we get 200X more net energy out of the water splitting reaction than whatever went into it, then known physics cannot help you, because there are no known working perpetual motion machines.  If that is the actual claim, and the wording of the claim certainly is deliberately misleading, then we can endlessly power this reaction using its Hydrogen output.  To date, all such claims have been certified Grade A "BS", and this sciency-sounding article provides zero pertinent details or explanation to distinguish between a 200X reactivity rate increase and total energy input compared to output.

I have to wonder about what the qualifications are for being a MSN science writer, because it certainly appears as if a baseline understanding of "Stanford Science" (scientific principles reducible to repeatable engineering practices) is not amongst them.  True breakthroughs are always a possibility, since our understanding of physics and materials science is far from complete, but we know enough to know that there are zero examples of working perpetual motion machines, thus actual science articles should not so much as intimate that without literal mountains of overwhelming evidence.

Re: Hydrogen Production Moving to Mainstream Green solution

For kbd512...

It would be helpful to know how efficient existing electrolysis methods of separating hydrogen from oxygen are.

It should be possible to discover how much energy is released when a sample of water is created.

It would be helpful if we had a familiar measure such as a kilogram of water to study.

If you have time and the subject is of interest, please post the amount of energy released when a kilogram of water is formed from oxygen and hydrogen gas.

Whatever that amount is, it is the amount that must be invested to recover the oxygen and hydrogen from the kilogram sample.

Next, if might be possible to find out how efficient existing methods are.


That "200" figure the article writer tossed out probably came from somewhere in the research, but it might have originally something like 200 electron volts or something equally minor.

Re: Hydrogen Production Moving to Mainstream Green solution

tahanson43206,

Is that enough of an explanation?

Here's what I think you could do with this discovery:
One could feasibly make the photovoltaic cell providing electrical energy input and the water-splitter the same device, thus you have a panel of active material that generates electrical power input using photonic input, for the express purpose of splitting water, and it requires no electrical conductor cabling, power conditioning equipment, or reverse fuel cells.  You still need water feed pumps, compression pumps, and something to power the pumps to compress the Hydrogen into storage tanks.  This tech doesn't do any of that, but it does take care of the water splitting problem without having multiple pieces of discrete equipment and energy-intensive materials to deliver and consume electrical power.

Could it be a better mousetrap?

I certainly hope so, but I would like to see what the limitations of the tech are before making any proclamations about it replacing reverse fuel cells, which are already about 95% efficient and commercialized technology now available from multiple vendors.

Re: Hydrogen Production Moving to Mainstream Green solution

Hysata's capillary action reverse fuel cell, Horizon's AEM, and one or two other companies have 95% efficient reverse fuel cell water electrolyzers.

Here's an article from National Renewable Energy Laboratory (NREL):
LOW COST, HIGH EFFICIENCY REVERSIBLE FUEL CELL SYSTEMS

Take note of the document's date (2002), take note of the efficiency targets (92% to 95%), and then take note of when Hysata released their previously experimental fuel cell technology (2024), meaning the projected efficiency goal was actually achieved and commercialized, some 22 years later.  Also take note of the fact that Hysata is not the only company to achieve that level of total efficiency, as Horizon AEM has a water electrolyzer that also meets the 95% efficiency target.  It's almost as if previously experimental reverse fuel cell tech was commercialized, and 95% is the present electrical efficiency capability of the current generation of tech.

With another 20 years of refinement, I'll bet 98% or higher is achievable.  What I don't anticipate, something that nobody else should anticipate, either, is that we've finally "discovered" a metal coated "magic crystal" that's going to output net energy when we pour water over it.

Re: Hydrogen Production Moving to Mainstream Green solution

I was surprised to find the original paper open for viewing ...

https://www.nature.com/articles/s41560-024-01674-9

The SAs of the chiral catalysts exceeded those of achiral electrodes in 1 M KOH. In particular, the SA of RhBiS at an overpotential of 300 mV exceeded achiral electrodes of RuO2, RhTe and RhTe2 by about 200-fold, 25-fold and 40-fold, respectively. The SA of RhSn was 1.76 times that of the achiral RhTe despite the stronger SOC in the latter. The Gibbs free energies further indicated that the activities of all Rh-based chiral catalysts were dependent on the SOC strength rather than following the free energy from a thermodynamic perspective (Supplementary Fig. 11 and Supplementary Table 3). These findings indicate the importance of structural chirality for the spin-related electron transfer in the OER.

and the summary:

Conclusion

We have uncovered a design principle for chiral catalysts that promote the spin-dependent OER, quantified the effects of topological spin texture on OER activity and presented the experimental evidence of a close relationship between the spin-amplified OER and SOC. Our results suggest that a strong SOC is crucial for generating high spin polarization in chiral crystals. The SA of RhBiS, which exhibited the strongest SOC among the tested chiral catalysts, was about 200 times that of the RuO2. Our work facilitates the design of highly efficient chiral catalysts for spin-dependent chemical reactions. Therefore, in future endeavours, the development of top-performing catalysts could encompass spin polarization as a fundamental property for chiral materials with SOC serving as a valuable descriptor.

My conclusion is that what the reporter picked up on was the discovery that one process was 200 times better than another process in the family of processes they were examining.  I deduce that this discovery might ? might reduce the cost of the process, but as kbd512 has shown, it is unlikely to improve the efficiency of the process in terms of energy expended.

In order to understand the implications of the reported discovery, it seems to me a human being would need to understand how industry currently decomposes water.  My knowledge is limited to images of bubbles of gas coming from electrodes in a Leyden jar in a classroom experiment.  Since this topic is available for NewMars members, if someone has the time and energy to find and post links to explanations of how water electrolysis is performed on an industrial scale around the world, this would be a great place for it.

I should also note that the 95% and 98% efficiency cited by kbd512 earlier today (2024/12/02) may NOT be the correct values for industrial scale equipment and processes in use around the world.

Re: Hydrogen Production Moving to Mainstream Green solution

Wikipedia's article on water electrolysis contains estimates of efficiency of existing industrial process that appear to hover around 80%. The article includes discussion of Real Universe conditions that reduce the efficiency, such as the need to remove salt and other impurities.

Efficiency
Industrial output

Illustrating inputs and outputs of simple electrolysis of water, for production of hydrogen.
Efficiency of modern hydrogen generators is measured by energy consumed per standard volume of hydrogen (MJ/m3), assuming standard temperature and pressure of the H2. The lower the energy used by a generator, the higher its efficiency would be; a 100%-efficient electrolyser would consume 39.4 kilowatt-hours per kilogram (142 MJ/kg) (higher heating value) of hydrogen,[59] 12,749 joules per litre (12.75 MJ/m3). Practical electrolysis (using a rotating electrolyser at 15 bar pressure) may consume 50 kW⋅h/kg (180 MJ/kg), and a further 15 kW⋅h (54 MJ) if the hydrogen is compressed for use in hydrogen cars.[60] By adding external heat at 150 °C (302 °F), electricity consumption may be reduced.[61]

There are three main technologies available on the market: alkaline, proton exchange membrane (PEM), and solid oxide electrolyzers.

Alkaline electrolyzers are cheaper in terms of investment (they generally use nickel catalysts), but least efficient. PEM electrolyzers are more expensive (they generally use expensive platinum-group metal catalysts) but are more efficient and can operate at higher current densities, and can, therefore, be possibly cheaper if the hydrogen production is large enough. Solid oxide electrolyzer cells (SOEC) are the third most common type of electrolysis, and the most expensive, and use high operating temperatures to increase efficiency. The theoretical electrical efficiency of SOEC is close to 100% at 90% hydrogen production.[62] Degradation of the system over time does not affect the efficiency of SOEC electrolyzers initially unlike PEM and alkaline electrolyzers. As the SOEC system degrades, the cell voltage increases, producing more heat in the system naturally. Due to this, less energy is required to keep the system hot, which will make up for the energy losses from dramatic degradation initially.[63] SOEC requires replacement of the stack after some years of degradation.

Efficiency
Electrolyzer vendors provide efficiencies based on enthalpy. To assess the claimed efficiency of an electrolyzer it is important to establish how it was defined by the vendor (i.e. what enthalpy value, what current density, etc.).

Conventional alkaline electrolysis has an efficiency of about 70%.[64] Accounting for the accepted use of the higher heating value (because inefficiency via heat can be redirected back into the system to create the steam required by the catalyst), average working efficiencies for PEM electrolysis are around 80%.[65][66] This is expected to increase to between 82 and 86%[67] before 2030. Theoretical efficiency for PEM electrolysers are predicted up to 94%.[68]

In 2024, Australian company Hysata announced a device capable of 95% efficiency relative to the higher heating value of hydrogen. Conventional systems consume 52.5 kWh to produce hydrogen that can store 39.4 kWh of energy (1 kg). Its technology requires only 41.5 kWh to produce 1 kg. It uses a capillary-fed electrolyzer to eliminate hydrogen and oxygen bubbles in the fluid electrolyte. Bubbles are non-conductive, and can stick to electrodes, reducing electrode exposure to the electrolyte, increasing resistance. Hysata places the electrolyte at the bottom of the device. Capillary action draws it through a porous, hydrophilic separator between the electrodes. Each electrode has complete contact with the electrolyte on the inner side, and a dry chamber on the outer side.[69][70] The effect of the build-up of impurities in the cell from those initially present in the feed water is not yet available.

Re: Hydrogen Production Moving to Mainstream Green solution

tahanson43206,

You're quite correct in stating that the efficiency of current pervasive industrial scale equipment is not 95%, because to this day industrial scale Hydrogen gas production relies upon steam reformation of Methane / natural gas.  There is no industrial scale generation of Hydrogen gas using any other method, because fuel cells cost a lot more money than a natural gas pipe and the much cheaper catalysts used to crack Methane.  However, in numerous pilot scale "green energy" setups (mostly for motor vehicles or grid energy storage) incorporating fuel cells and reverse fuel cells as energy backup, these reverse fuel cells, using the latest commercialized tech, are indeed 95% efficient and that has been independently verified six ways from Sunday.

The "Gold Standard", or "Platinum Standard" for fuel cell catalysts, such as it were, is Platinum.  The catalyst is loaded / "adhered to" some kind of supporting structure, such as a fine wire mesh membrane inside a normal or "reverse" fuel cell.  You could substitute the fine wire mesh for CNT, thereby achieving much greater surface area, at greatly reduced weight, if reaction rate or fuel cell weight is a problem.  The latest tech, which was finally commercialized this year, is capillary action or anion exchange membranes, both of which achieve 95% electrical efficiency.  That means if you put 100kWh of electricity in, then you get 95kWh worth of Hydrogen gas as output.

That doesn't mean a fuel cell which reacts Hydrogen with atmospheric Oxygen is 95% efficient, because normal "air" is mostly Nitrogen by weight and volume, merely that the process of splitting water has now become 95% electrically efficient.  The closer that process comes to 100% efficient, the better, because you still need additional energy to compress the Hydrogen gas.  Compression consumes lots of energy.  The reaction inside a normal motor vehicle fuel cell that produces electrical power output is nowhere near 95% efficient, so far as I'm aware, more like 50% to 70%, and 75% seems to be the upper bound.  If said vehicle had a tank of pure O2 onboard, then its efficiency might be higher, but so would its operating temperature, and at some point a normal PEM and Alkaline fuel cell will melt down without cooling, thus the waste heat from the reaction is the energy sink associated with using a normal fuel cell.

If this new chiral crystal tech can replace Platinum catalysts while providing the same electrical efficiency as a Platinum catalyst, or become a solar-direct-Hydrogen option (no separate reverse fuel cell), then that's a "win", because it means the cost of the entire device or at least the catalyst is lower.  If the catalyst can be a common metal, then any kind of PEM fuel cell is far less expensive, when mass produced, in comparison to a short-lived electro-chemical battery, and the vehicle it powers has roughly the same weight as a gasoline powered vehicle, so it has the same power requirements, but uses less energy overall.  All the measures taken to improve power electronics and electric motor efficiency still benefit fuel cell powered vehicles, but the size and weight of the "fuel tank" is no longer a substantial portion of total vehicle weight.

The "big win", would be finding a replacement for Platinum or the entire reverse fuel cell device, such that only the vehicle itself requires a fuel cell to consume the Hydrogen, and that fuel cell no longer requires special metals like Platinum.  We could also go mine one of those pure Platinum asteroids, and then finding a more abundant substitute for Platinum is largely a moot point.  That said, when you can use abundant materials in novel ways, that is generally "the best method".  Thus far, there are no acceptable substitutes for Platinum.
