Hydrogen energy storage in AMMONIA: Fantastic future or fossil fuel scam?

Hydrogen energy storage in ammonia is not something that would be instinctively obvious to most of us, but the folks in the energy industry are apparently getting quite excited about the concept. It's a far safer, easier and more energy dense way to transport hydrogen around the world and could be the final cog in the gears of a true hydrogen economy of the future. But some warn that it could actually be a smokescreen enabling the fossil fuel industry to continue burning huge quantities of natural gas and maintain their vice-like grip on the global energy market.

    This video leapfrogs the main problem that we have with hydrogen. Transporting the stuff isn't really an issue, creating green hydrogen in quantities big enough to make a difference is. The infrastructure deployed to generate and transport the renewable electricity to power the green hydrogen electrolysers is significant, whilst the electrolysers draw a huge amount of renewable power to make a relatively tiny amount of green hydrogen. The idea that green hydrogen will ever usefully mitigate the alleged man-made CO2 global warming emergency is a fallacy.

A new technology we do have here in Australia is the capture of CO2 from emitters, processing using a our patent 'Annulus Core Reactor', to product a reactant solution of ammonia bicarbonate. We then further process this into add-value products for the agriculture, pharmaceutical, and other industries. Whilst still advancing and moving on from our 2nd pilot plant, already engineering confirmed along with independent analysis of by-product - 99.3 & 100%. We see it as exciting times to assist in both the transitioning period and also future negative carbon footprints.

    Great presentation! Always a good time hearing you talk :) When it comes to good or bad hydrogen I strongly believe we as a population can't "go back". We will never go back to not manufacturing on industrial scale or not travelling the world until nature forces us to. So the only way forward is just that: Forward. If there is economic winning in developing clean hydrogen/ammonia production, it will be done. The same with carbon heavy production. I think the big question here is: Will "green" ammonia production be more profitable than trying to synthesize high energy density fossile fuel or battery solutions with good enough energy/weight ratio? If Yes, then ammonia will be the new "green" fuel. There will always be dirty methods to produce or refine energy, and until they're not profitable anymore, those methods will be used, so I welcome any chance or attempt to find some way to make fossile fuels economically obsolete.

What you describe as market forces in agriculture is actually a huge political network steered by big agriculture, big food and chemical firms, with huge assistance from news outlets that scream from the rooftops at any suggestion that people - correctly, by any objective measure - might have to change their diets to save the planet.

    ​@@ricos1497 ...I agree with your analysis in general. What you haven't solved is the problem of big ag dominating all its lesser parts - from the farmer's point of view, the market is very real, even if it is horribly distorted by powerful influences in the background. From the point of view, for example, of Nutrien (Formerly Agrium Inc. and PotashCorp), the task is simply to dominate "the market" to maximize profits. Big businesses have much more actual power than a single farmer. But would you suggest the collective farm approach that the Soviet Union used? Their systems of top-down management by distant bosses caused starvation in their country. Ditto for the Chinese some decades back. Open, free markets work better, especially for price discovery, even though they don't adhere to all the theoretical concepts underlying the word "free". This is a conundrum that is particularly stark in the American economy, where political influence is overtly available to elites since indirect bribery of politicians is legal {I refer to the 2011 "Citizens United" decision of SCOTUS}. Economist J. K. Galbraith discussed these issues in multiple books he wrote in the 1950s ~ 1980s wherein he pointed out that big American business practiced very similar "planned economy" techniques to those of the Soviet Union, which helped big business to dominate, while at the other end of the spectrum small farmers were entirely exposed to the brutal realities of open market practices. I have no solutions to offer, but we must at least begin with honest awareness of how things work. BTW, I object to the phrase "save the planet". Earth has been around for billions of years, and will exist billions of years into the future. If what you mean is "save humanity from its follies", I'd recommend saying so explicitly, which more clearly reveals the task at hand & motivates you to offer detailed fixes to the problems you perceive. Repeating platitudes is a lazy form of virtue signalling without practical merit. What " technology to produce plentiful food anywhere in the world " exists?

They used large amounts of ammonia in industrial refrigerators (which I believe is a still-used technology). Through him I learned that there were civic contingency plans to evacuate half of the city, should a major ammonia leak occur. Yes, ammonia is hydrogen-dense and may by a good way of storing hydrogen, but another problem with it, besides the current lack of efficient, carbon-free industrial scale production technologies, is the not inconsiderable toxicity.

    I wish those green-ammonia researches every success! However, as shifting off dirty transport fuels onto clean ones is a decadal process, we could ask ourselves why our cities require so many cars in the first place? What if we built not just energy efficient transport, but energy efficient cities that used less transport in the first place? New Urbanism is a movement that builds an attractive town square above a subway and surrounds that square with shops and services. It immediately becomes a vibrant human-focussed place of work, rest, and play. Unlike an oversized suburban Mega-mall which is a 20 minute drive away (plus parking time!), a local town square is a 5 minute walk away. Unlike a Mega-mall serving 300,000 people from suburbs scattered far and wide, a town square serves the local 15,000 people. Instead of being oversized and full of strangers, they are intimate and community creating. Loneliness is becoming a health epidemic up there with heart disease and cancer. Town squares solve loneliness while also encouraging walking and reducing obesity. There are many benefits. It decreases car use - and makes a car-free lifestyle viable. This has benefits for the poor. It decreases the size of our cities down to 20% or 10% of today's massive suburban sprawl. It decreases our carbon emissions, traffic jams, loneliness, environmental impact, and even the size of our waistlines! Studies and videos here. eclipsenow.wordpress.com/rezone/

    I too like the liquid air approach. It uses existing technology . It doesn't require any form of chemical processing,conversion. It would be only applicable for static installations. So doesn't answer the heavy transport question. Hydrogen split from water used in existing infrastructure is a great idea for this. Which could be done at a liquid air plant , I think it would be compatible, pressurisation tanks ,cooling etc, liquid air tanks and liquid hydrogen tanks. Which is exactly as you said, we need to look at all options and develop them . Hydrogen would also be safer than ammonia. Could ships split hydrogen from sea water using solar? My guess it would lead to slower steaming as the amount of panels surface area needed would be large, which imo could be a good thing. Futures so bright 😎

Would like to see a similar video on Methanol at some point with its own health exposure issues, though the exposure concentrations need to be a few times more than for Ammonia. It starts getting quite interesting when you compare these two and the places they have the most strength in.

    All good analysis and overview. The dependence on ammonia for agricultural needs should not be underestimated. Currently nations like Trinidad and Tobago are significant players converting abundant gas supplies into fertiliser that is shipped globally. The investment, scale and time taken to replace with renewables will be large and long. It inevitably will have to occur. The scale should not be underestimated though and global food production depends upon fertiliser or the world starves, using ammonia as a fuel is a good idea and hopefully bears fruit. Personally I think stand alone solutions that use hydrogen or ammonia to displace the need for expensive battery technology are the way to go, removing households from the grid for both electricity and space heating where possible and reducing the demand on the generation and transmission infrastructure to allow it more flexibility to supply homes unable to self generate or that are only partially self supporting. I also think we need to move to intra day trading of electricity so homes can provide excess energy at peak times at a fair price to support the overall system and provide a return for those able to invest in distributed self generation. Why pay ridiculous sums to French and Chinese companies to build nuclear when we could pay the same or less money to enterprising Brits to invest in home generation, storage and supply systems that would be more reliable and less risky without transmission losses. That said I am in favour of the Rolls Royce initiative yo design build and install small nuclear reactors close to demand centres hopefully using waste heat for horticulture or space heating.

    Huh? All these low-carbon fuels require massive amounts of renewable electricity. It makes no sense to use "standalone solutions" to remove houses and businesses from a grid overflowing at times with cheap renewable electricity. There's no scenario where it's cheaper for them to make and store their own fuel locally, and it's not obvious that it would be less expensive to distribute fuel to them than to improve local electrical distribution; when everyone has a BEV and heat pumps, they will use them to smooth out electric demand which makes transmission and distribution easier. As Michael Liebreich of Bloomberg NEF says, leave green hydrogen for the parts electrification can't reach. CleanTechnica had a good article "Is Hydrogen The Best Option To Replace Natural Gas In The Home? Looking At The Numbers" debunking the idea of home hydrogen.

Hydrogen will be expensive to distribute due to its issues and if NG infrastructure is to be used suggests switching overnight.... unlikely and expensive to trash all the gas boilers and fires. I also thing hydrogen will not be good to replace my nice log effect gas fire due to water saturating my flue and having condensate running back down - corrosion. I like the idea of storing a gas over summer from excess hydrogen or ammonia to use it for electricity and heat in the winter for a standalone system. I would think storage would be less expensive than batteries and have 100% capacity over its life unlike batteries which will die. I have a 55 deg slope on a south facing roof in Scotland so ideal for inroof solar. My problem is winter will be low generation due to weather. In Scotland there is already too much wind in winter as the government paid £69 million in Jan Feb 2020 to wind farms NOT to dispatch electricity.... £10 per person and increasing fast. This gets added to my bill with electricity already 15p (18 us cents) per kWh. Gas is 2.5p per kWh. A 6 to 1 difference. Electricity will increase in price due to building wind farms and nuclear plant. This makes domestic generation attractive (and natural gas). Renewable electricity prices are making modern western economies uncompetitive and introducing fuel poverty to older people on low pensions and low income people. I see a future with small distributed generation feeding back into the grid reducing grid losses and expensive upgrades to grids which will reduce electricuty prices through competition and reduced cost of infrastructure.

Since producing enough energy from renewable source will be an extreme challenge post-fossil fuels, the efficiency of storage systems will be critical. Chemical batteries are probably 90+% efficient and if hydrogen or hydrogen ammonia is only 25%, then it is a non-starter for widespread applications regardless of its other positive characteristics. So, how efficient are these processes? What is their energy cost?

First of all, infrastructure to use ammonia as a fuel just isn't there. You can create and transport ammonia sure, but to use it as a fuel just can't be done at the moment. Secondly, methane (as in synthetic, biogas etc. renewables) has very similar, well known processes in all phases. So it is better just because all needed infrastructure is already there and built. All that is needed is to ramp up production and get those processes to same cost level with natural gas. Which can be done by carbon taxes on use and giving those revenues to sustainable methane producers as subsidies. Third, emissions from ammonia would be NOx gases because of temperatures involved.

But using it for traditional passenger vehicles is not where the market would be anyway. It would be for long-haul trucks, planes, ships and perhaps farm equipment. And while NOx is a concern when burning ammonia as a fuel, we generally already know how to reduce it to safe levels because typical fuel combustion also generates NOx. It should also be highly reduced if it is Fuel Cells that process it, which is the preferred way to utilize it. Yes methane is a great energy carrier, likely superior to ammonia, but you would have to supply a carbon source to create it synthetically, which will require extra infrastructure through carbon capture, which ammonia does not need.

Ammonia, in this context as a storage medium, is easy to make and easy to unmake. That's the biggest advantage. The problem with reversible hydrocarbon storage is the proclivity of carbon to bond to itself - in essence making coal - in one or more steps of processing. Solids plug pipes. Nitrogen doesn't do that.

And while it may be an overly pessimistic outlook on ammonia or hydrogen as a fuel generated by renewables, it does suggest we won't be able to meet our current demands at any rate. It seems our demands are overall just too high to be sustainable. And considering our global greenhouse gas emissions that is even just considering those who are fortunate enough to have walled and heated houses and perhaps a car. Lots more will follow to demand even more than what we already do. This is quite a depressing situation. Much more so than Covid-19 imho. Some people considered Covid-19 as a chance to display community and our problem solving skills as humanity as a whole. A practice trial, if you will. Before the real disaster strikes. The verdict can only be that we have utterly and completely failed all over the place except for a few nations such as Australia and Taiwan. This does not bode well for our future and I fear the worst. And fear is a strong word, but I do begin feeling it. We employ technologies such as wind energy while neglecting the cost they actually concur over their lifetime because.... We are missing vital optimization points that we could work on, but there is no incentive to really move forward, because the buyer will still buy at that price, for that performance. Politicians are slow to act and shy away from it. We've spent literally billions to relieve the economy of the sufferings that come with Covid-19 but no way in hell are we willing to spend nearly as much to tactle this much more dramatic and long lasting issue. Because we only ever react to what is immediately in front of us. If it's not there yet...why do anything at all? Sadly this system doesn't work like that.... And Covid-19 didn't either, it was well known in January and virtually all governments blundered and started to prepare in February, 60 days later than possible.

    Nuclear is quite capable of meeting our needs dude. People are just afraid because they're not familiar with it. Spend a year submerged on nuclear powered submarines as I have and you will know it's a great source of power. :) Geothermal is another example of something that works 24/7, you just need a suitable location where water is constantly being replenished and heated by the earth, waiting for you to release it to turn a turbine. They're working on systems where the water source would be artificial (waste water) and pumped into the ground artificially right over a naturally hot source, but there's a balance...some locations will cause earthquakes if you pump too much water in or you can only use them for a period of time before they start causing earthquakes every time. Solar and wind COULD do it, but you have to build out a lot. You have to ask yourself if you want to cover 1% of the desert with solar panels. A better option for central power might be to put them in orbit, where there are no clouds and night is brief, and just transmit it down to earth with a microwave laser (aka maser). Personally I think nuclear is the answer for central plants, and also put solar on everybody's roof. But we need people to not be afraid of nuclear. :)

    Did I miss it or was there no mention of the hazards associated with anhydrous ammonia? Although historically there haven't been many cases of accidents with ammonia, the dangers are worth mentioning. With a ammonia/hydrogen based economy I imagine trucks and pipelines would eventually carry it everywhere gasoline is distributed to now, so accidents are bound to occur. While it's true that the extremely strong odor would be a good warning to people who might be wandering near an ammonia leak, it may also be difficult to avoid in some cases. Confined areas would be a huge concern but they aren't the only risk. Normally anhydrous ammonia (100% pure ammonia) is lighter than air so it will tend to dissipate somewhat when outdoors, but in the presence of moisture (such as high relative humidity - looking at your Florida), liquefied anhydrous ammonia gas forms vapors that are heavier than air. In this case a leak or a spill could be extremely dangerous. Breathing in ammonia vapors would cause burning of the lungs and airways leading to extreme respiratory distress and eventually suffocation due to the body's attempt to defend itself - essentially, you end up drowning in your own mucous while your lungs, throat, and eyes burn in excruciating pain. Not pretty. This is why hazard training was needed at my previous employer where I worked near anhydrous ammonia, which was used as coolant for satellites etc.

    The problem with hydrogen is the energy loss in production and use. Currently, there are three ways to produce hydrogen, it can be produced from methane (just burning methane is more energy efficient and this method creates huge amounts of CO2), it can be produced by leading electricity through water (about 30% energy loss) and the most modern way, membrane separation (about 20% energy loss). The last method is the most popular. And as said in this video, you have to cool or pressurize it (30% energy loss). The most modern way of using hydrogen is by using a membrane that instantly turns it into electricity (the reverse process of membrane separation). This results in yet another energy loss of about 20%. You could also just burn it. I am not sure about the rendement of burning it but since most engines burning fossil fuels have a rendement that's usually not higher than 30% I think the membrane method is more efficient. All these things considered you lose about 70% of the energy you put into producing and using hydrogen. And after all, this isn't energy production, it is just energy storage and transportation. And most energy used to produce hydrogen is produced by fossil fuels. There are however projects running to produce hydrogen using sunlight. This may make hydrogen a better energy source.

    Grid scale hydrogen fuel cells represent a cost effective way to deal with fast changes in demand and deal with lapses in power from renewables due to seasonal fluctuation. Households should only have a battery large enough to get through the mean energy usage day of the year. If we solve this will batteries instead of hydrogen that means at least doubling capacity and in many places there can be lapses of over a week which means 7x battery capacity. There's a reason the existing grid is demand based. On the good days you could charge up hydrogen or pumped storage and then on the bad days used that storage. Of course that process is not 100% efficient which requires energy generate to be overspeced but wind and solar is far cheaper than batteries even if the hydrogen conversion done with hydrolysis and fuel cells this system could still work and probably cheaper than the current natural gas plants. So the overarching point is we can be doing hydrogen right now. Later we can improve costs for with something like ammonia which also has potential in transportation.

    At "low" temperature - no, at high temperature - yes. This is btw also one of the reasons why running gas turbines as peakers are a bad idea (as baseload operation there is minimal NOx, at ramping temperatures there are a lot of NOx produced (due to the nitrogen in the atmosphere and the excess temperature used to increase activity)). (The standard mitigations techniques revolve around either feeding a nitrogen deprived atmosphere (ie: oxygen, or oxygen/CO2 mixes) or lowering the peak temperature (by injecting steam for instance)). If burning the hydrogen when it has been "cracked" from the nitrogen it is "only" the atmospheric nitogren you have to contend with (see above parenthesis)

An ammonia fuel cell powering the aircraft may be a worthwhile option.
