Sustainable hydrogen made possible with a new catalyst

This video shows gas bubbles being produced by water electrolysis using a new mixed cobalt manganese electrocatalyst. Unlike current standard methods, this catalyst is not made from rare-earth metals, making it a more sustainable option.

Awesome! "Eventually, the team overcame these issues by trial and error, and discovered an active and stable catalyst by inserting manganese into the spinel lattice of Co3O4, producing the mixed cobalt manganese oxide Co2MnO4."

[@dan2304]

Catalyst only lower the activation energy but have no impact on the energy needed to electrolise water. This may increase the efficiency of producing hydrogen from below 80% but does nothing for the high costs of storage and transport or the low efficiency and high cost of fuel cells.

[@exukvera]

Toyota is in the final stages of developing a combustion hydrogen engine. Other companies are working on solutions to store it at room temperature but only time will tell if any of them is commercially feasible.

[@dan2304]

@@exukvera A fools folly. Once oil and natural gas supplies drop below the elastic demand and that is only a few years away the cost of producing H2 will increase proportionally. Private motor vehicles will be a luxury for the rich as was the case a century ago, no matter the energy source. A decade or so after that food supplies will become a serious problem. Problem for people to be able to pay for. The only accurate thing in economics is: "Supply will meet the demand that has the ability to pay". The ability to pay is disappearing for a large portion of the global population.

you could simply hook a car battery in the trunk to the system with an amplifier like to a car stereo and you wouldn't have to store hydrogen you can generate it on demand and as a gas it doesn't have to be atomized by the fuel injector so it's more efficient

The catalyst is likely made of a solution of Mn(NO3)2 and Co(NO3)2 in a specific ratio saturated dissolved in water then diluted to 4-8 times its volume in a carrier like methanol/ethanol. and baked at 410C in several layers.

One of the most pressing issues we face today is finding a renewable and environmentally friendly solution to transport and logistics. Hydrogen holds immense promise as a potential solution to this problem. Hydrogen can be used to power Hydrogen fuel cell cars or can be used in certain types of ICE such as a liquid piston engine. If Hydrogen could be produced rapidly end efficiently using a catalyst then it's possible that one day cars could generate their own hydrogen to use as fuel. The fuel tank could contain a catalyst and would only need to be filled with water. If the catalyst makes the process efficient enough it doesn't matter if it requires electricity. The hydrogen could then be used as fuel for a liquid piston rotary engine (these engines work well with hydrogen), and the only emissions would be steam. If this is possible then I hope this is the direction green automotive technology goes in the future. Cars would handle very similarly as they'd still be using an ICE, but running costs would be so much cheaper and it'd be good for the environment. it would reduce the cost of living a lot. it would practically eliminate fuel costs, and because it would make the transport of goods so much cheaper, logistics networks costs would be massively reduced which would cause the price of goods to come down a lot.

[@alfianfahmi5430]

One thing that needs to be tackled if we want to use catalyst, though, is the availability of said catalyst.

[@EddieTheH]

Liquid piston is pointless when fuel cells exist, are less prone to failure and more efficient.

[@KrishnaSharma-gg1eh]

That is true but we still need a safer way to store hydrogen

[@jozefnovak7750]

Super!

[@ekimnamtnuts]

I am curious about whether it will at some point be possible to create a hydrogen on demand combustion vehicle? Ie just enough hydrogen would be produced at any passing moment to be injected and combusted inside an adapted engine so that it would not have to be stored. I think the main argument against hydrogen combustion is that hydrogen needs to be stored in compressed tanks. What if it didn’t? What if you completely bypass storage and have the catalyst progressively only making enough gas to drive each piston at that given second in time and then keep creating more for each explosion as time goes on. Will this ever be possible? Obviously there would still have to be an electrical component to split water but if the demonstration in this video is accurate it appears that it may very well be possible and also efficient enough to replace petroleum and battery only vehicles? I’m not saying it is possible yet but could it theoretically be done?

[@m3sca1]

daniel dingle, archie blue, stanley meyer, herman p.anderson... now go research

[@jimj2683]

Then you need to store the electricity to release the hydrogen fromt he water. This will require even bigger batteries than a normal EV because of the lower efficiency.

[@chinedubalone2107]

Yes, my company have created a technology that converts hydrogen into a battery that can be used to power vehicles and devices...

[@ekimnamtnuts]

@@jimj2683 It's unclear from the demonstration how much hydrogen is actually being produced in volumetric terms and therefore difficult to tell if it would actually be viable. We're seeing the electrical input required to release varying amounts of hydrogen but unless there is a measure of how much hydrogen is coming out then it remains something of an enigma. Perhaps one day it will be possible to do what I asked in my original question but I'm sure there are plenty who will say that this is impossible due to the physical limitations of thermodynamics. Have you seen the video of Genepax in Tokyo? Looks like they had a little car which was splitting water somehow and reconverting outputting as electrical energy to drive their vehicle. Seemed a bit suspicious and the company has since disappeared as far as I can see however the videos do look convincing. I suppose looking at this whole concept from the outside with limited knowledge of physics and chemistry, the big question is can we not use hydrogen as we literally have seas full of it. I agree that splitting H2O is the problem. It's all about input vs output. If the amount of hydrogen being released in his video can produce energy that is close to the charge being applied to release it then perhaps viable but I doubt it's even close at this stage.

[@westonloomis]

If the catalyst makes the process efficient enough it doesn't matter if it requires electricity. Electricity can be produced renewably and efficiently (Nuclear power is a particularly powerful and benign source of electricity).

[@methylene5]

It's not economical to use electricity yet, because much of our power comes from fossil fuel power stations that are only about 30% efficient in generating electricity, the rest being waste CO2. So you reduce carbon emissions substantially by putting available electricity into the power grid, rathan than electrolysis. However, in time that could change.

Ideally, the electricity being used would be from a renewable source. but in this context, sustainable is mostly referring to the catalyst.
