Right now Ammonia is the front-runner as a carrier for Hydrogen for future fuel-cell vehicles, so the "Powerpaste" really needs to be measured up against it as they perform the same function as Hydrogen carriers. The problem with it is that the reaction to produce Hydrogen from Ammonia doesn't completely convert all the input Ammonia, and is thus very wasteful. Also the unconverted Ammonia is itself a pollutant and will thus need to be scrubbed. If a process is found to convert close to 100% of the Ammonia then it will definitely be the carrier of choice as the only output will be Nitrogen (70% of air) and Hydrogen (which is then reacted in the fuel cell to form water.). You can't factor in the price of Magnesium Hydroxide in your equation, because there is only a limited use for it in producing medicine and as a food additive. It's expensive because of the low production numbers. If it available as a by-product in huge quantities (imagine amount of depleted powerpaste cartridges that will need to be scooped out if every car uses one or two cartridges each week.), its price will crash and uses for it will be saturated, especially if it can't easily be recycled back into powerpaste. We're not even counting the cost of collecting, cleaning and transporting it. Compare that with Ammonia where the Nitrogen and water by-products can simply be released straight into the atmosphere from the vehicles (assuming 100% conversion or remaining Ammonia is scrubbed), and the Green Ammonia production plant can simply draw in air and water, add electricity generated by renewable sources, and complete the cycle. (Again assuming they can perfect the process). No return of by-product material is required except for maybe the Ammonia scrubbed during the process.

So Thorium for power grid and thorium to produce the past for the transportation sector. As for back up power for homes and hospitals again something very easily achievable .

Man. How many hoops are they going to go through to get to a hydrogen economy? Sorry, I'm a business major. I studied alternative fuels and their probability into entering the marketplace. There was a company called Stuart Energy from Canada about 20 years ago that originally made small hydrogen generators for labs. But then they got really ambitious and imagined scaling their process up to create hydrogen vehicle fueling stations. With the help of the Canadian government they produced a demonstration fleet of hydrogen powered busses that were fueled by their "Hydrogen Appliance" from tap water. They put the tap water through a demineralizing process, but it didn't need to be distilled water. I thought they were on to something, but they were bought by a company called Hydrogenics of Canada around 2005 and I haven't heard much about anything going on with the company since. The big problem with hydrogen is that advancements are happening much slower when compared to EVs. When affordable EVs were truly introduced into the market with the Nissan, Leaf ranges were low because battery energy density was low and cost of the vehicles were high mainly due to the cost of the batteries being high. However, these were the only hurdles keeping EVs from taking over the transportation sector. Fuel distribution already existed in the electrical grid we use to run our appliances. Now that batteries have come down in price and keep dropping, and electric car prices are getting more and more affordable, while ranges have passed 200 miles as the base, the invisible hand of economics is persuading a lot of people to buy EVs. EVs are much cleaner than petrofuel cars and the grid keeps getting cleaner making them cleaner even as the vehicles themselves get older. In my educated view, EVs win because battery cars have ranges that are now comparable to gasoline cars, they charge at home which can't be more convenient and give you the full range of the battery every morning, their prices have come down to be closer to the prices of gasoline cars, the cost of fueling and repair are one tenth or less than that of regular combustion engine cars, they are quiet, contributing far less to noise pollution, there is a long distance DC fast charging station network being built out for them as we speak and one already exists for Tesla's electric vehicles, AND they are much cleaner than gasoline or diesel cars and are getting cleaner as emissions free sources of electricity, like wind and solar are added to the grid. The cleaner bit being the only real reason, mentioned in the above video, for still considering hydrogen and the goop stuff as viable. When comparing EVs to hydrogen vehicles, from a business, management and speculative future investment point of view, there is no comparison. To move to a hydrogen economy we first have to remove the problems with hydrogen, that is production, distribution, storing, compressing, dispensing, and using (the vehicles). Given all the hurdles hydrogen needs to overcome to supplant battery electric vehicles, you come to the same conclusion. Hydrogen is "A Big Pain in the ass" when compared to EVs.

i am totally a science-luddite, but it seems to me this is a perfect backup power supply. if a town or city were suddenly plunged into darkness, having a backup generator that used this stuff for medium-term power loss would be great. if it doesn't deteriorate over time then it's perfect for long-term energy storage, which typically means emergency and backup systems which do nothing for long periods of time. i suppose there could be a commercial use in refrigeration, any industry using refrigeration needs a good backup power supply, and i recall diesel is usually the choice - but diesel can expire after a time if not used. if this stuff is more long-term stable, then it may be a good replacement. it looks like it could do the job better and greener, and to refuel you just replace the cylinder of paste. a shipping container could use it as a backup. shipping containers are supposed to be powered by the ship, but if there are mechanical issues you might not know until you open it at the destination (too late). having a built-in generator in the container to take over when the primaries fail could help there, and probably lower insurance costs on refrigerated shipping too.

It talked about using extreme heat (3 Mile Island), copying nature with photosynthesis and using catalytic material to generate hydrogen. Magnesium fires can not be put out with water, hydrogen is catalyzed out and adds fuel for burning. It would be interesting if this can be developed as a fuel alternative for vehicles in the near future (before 2035).

Isn't ammonia as a storage medium, better?

The major problem with hydrogen is platinum for the fuel cell stack. Can't make it remotely affordable while it requires a significant quantity of one of the most expensive metals to make it work.

FWIW: An advantage to using hydrogen is that EXISTING internal combustion engine powered vehicles can be converted to burn it, as well as using it in newer fuel cell vehicles.

Thanks for this! A similar technology that's claiming to be pumpable is Hydrilyte, which is being commercialized by an Australian firm. Looks like they're using mineral oil as their buffer liquid!

I worry that "Niche cases where higher costs can be justified" will just translate to "Now we can have military drones staying in the air for longer"

I know what you mean. The lure of WW3 to bail out the global economic scheme, business as usual, may prove too tempting to the obtuse powers that be.

This sounds like the first really alternative to the current metal-hydroxide hydrogen storage systems! Great Video !!!! Keep it real :) o.o/

Fraunhofer isn't a company. It's a science service provider and the biggest one in Europe. They hold 6131 patents.

In Canada we have hydro dams producing excess amounts of electricity holding back huge water reservoirs. Isn’t that the cheapest clean way to produce hydrogen?

There is a major problem with hydroelectric dams. They flood large areas of forest that cause vegetation do die thus causing methane gas. Methane being far worse green house gas than carbon dioxide.

I think you may missed a point, the dams already exist. No methane. Also the problem can be mitigated with new dam construction by clearing the basin, . This won’t happen though due to cost compared to renewables.

Celebrating 0 cost energy is like buying groceries, and then 2 minutes later being happy that you can eat the food in your bag for free. Negative energy cost is not something positive (no pun intended), it's just the evidence of mismanagement of the power system. Not to mention that it's only 0 to negative cost for the end-user. When power cost goes below 0 that means your government invested into generators that are only active for a limited amount of time and/or produce electricity in an unpredictable manner. There was still a lot of taxpayer money invested into those generators. Also this power paste relies on the improvement of a LOT of other areas.

hahahhaha, Bob Lazar, years later thinking, "why didn't I think about the medium as a paste????, that would have been legal to make"...

13:49 Another major issue with negative grid pricing (as you note there's there will be many claims on the excess energy) is the fact that there are already companies that make smart grid charging for EVs so that when the advertised price goes low or negative, it turns on the charger for the car for people to potentially get paid to charge their car. Clearly, with all the new EVs coming out and more having the flexibility to charge when they want since their range is so much more than customer's daily commute it's very unlikely there will ever be negative pricing (excess energy) in the future to make capturing it with hydrogen very economically feasable.

Speaking of "less CO2 in the atmosphere from hydrogen fuel": While swimming in the sea, did you ever noticed that in the dirt patch water is warmer than in the cleaner water around? The dirt/debris is not as transparent as the sea water, absorbs more of the sun energy, warming the water in the patch. Do we know for how much those giant floating waste patches make the oceans warmer? Is the CO2 in the air the only cause of global warming? Could it be that plastic waste also helps?

You compare the energy density of power paste to a Tesla Battery, except you left out all the equipment and water necessary to generate electricity from power paste. Whereas the tesla battery is ready to deliver.

Toyota has invested a small fortune in HFC cars and there is a lot of face saving for them to stick with it in the hope they can fix its endless shortcomings. Batteries are getting cheaper and better at an incredible rate and while a Tesla has 480kg of battery weight, around 95% of the energy expended in accelerating that up to cruising speed is recovered using regen breaking down to 0. I know this from the science and the simple fact that my Tesla (any EV with max regen enabled) shows consumption is more dependant on the daytime temperature than the terrain. I go for long winding drive up a 500m hill (about 15km) and drive down again and find my consumption is 172Wh/km and same distance on more or less level ground on the same day/time/temperature is about 168Wh/km. That suggests weight is not the biggest impact on consumption. I do about 380km on a charge and of course that full charge costs me $14 or around 3.7c per km. I doubt any hydrogen car is going to meet that cost per km. Also the maintenance cost of an EV is ridiculously low because of its amazing simplicity. So that leaves stationary power, and yep that may be what hydrogen storage is good for, but again looking at how batteries are advancing eg there is a liquid metal battery that handles 10,000+ complete charge cycles and costs a pittance so nah I think green hydrogen will only be used for industrial processes and blue & grey and black hydrogen not at all.

Everyone loves to compare fuel alternatives to Lithium batteries. However, batteries can be recharged, which makes the comparison void. Have an alternative that needs reprocessing? Now you are talking about removing the battery, remanufacturing, etc. Lithium batteries are better at one crucial thing, which is recharging, in place, with only electricity. And that is the only real advantage they need to beat out other technologies.
