@@keithwhite5657 I disagree. They think about their people first and they are wiling to try master the best energy sources in order not to depend on others. Nuclear is their best hope and people don't get that it gets a lot of knowledge to master such amazing technology. In Japan there's almost no natural resources for energy and they learned that depending from the US or China is no option.

The Helium cooled pebble bed reactor is just one of the reactor designs capable of producing very high temperature process heat for Hydrogen, ammonia, etc, along with molten salt and Sodium cooled designs. Its disadvantage is that the waste ceramic pebbles are more difficult to reprocess than conventional fuel rods and thus less amenable to reuse of waste stream U238 and Pu in breeder reactors. MSR and sodium designs can be breeders, fueled by waste and produce dramatically less and shorter-lived waste streams than the current Japanese design. They are likely better future designs, but the Japanese deserve credit for pioneering a better replacement for the expensive water-cooled reactors we've been stuck with for decades.

No,completely wrong, the TRISO fuel is never reprocessed,it isn in it's final storage form,where it will remain for millions of years until it rides tectonic plates deep into the Earth where intense heat and pressure will destroy it. No body has been worse with nuclear energy except the Russians ,who are so corrupt and incompetent to be in a seperate category. The Japanese are the worst ,they have good reactors ready to produce energy but they are very backwards and ignorant, ruled by fear, just like the Germans. The Japanese have cost the Europeans and the poor of the world to spend tens of billions extra for gas and coal, funding Russian aggression.

1968 Hamm pebble reactor accident on internet

Japan is surrounded by water, salt water that can easily be broken into 2 parts Hydrogen, 1 part Oxygen. Both elements can be used chemically to produce energy, under the right applications. Even in high school in 1964, for a science project, I demonstrated an apparatice to break apart a salt water solution into H2 and O2, collect the gases, compressing under low pressure both gasses separately and powering a simple steam engine, built by a class mate. We won science fair ribbons. A novel thing to consider back when gasoline was maybe 15 cents a gallon. Maybe when gasoline is 15 dollars a gallon, people will have more of a use for Hydrogen technology.

There's already one operating and connected to the Grid. It's China's HTGR, but it operates at a somewhat lower temps compared to Japan's HTTR design, 800C vs 950-1000C from Japan's design. China's design is a pebble bed reactor, it works kinda like a gumball machine where the TRISO fuel is fed from the top of the reactor. Japan's design is a prismatic block type, though not really sure why there's a difference on the operating temps.

To create Hydrogen you can pass current through water it breaks the bond between the Hydrogen and oxygen the problem is a lot of energy is required to make Hydrogen and with some of the energy being fossil fuels it is not carbon neutral or good for the environment. But I watched a video on KZread that was about putting solar panels in the Sahara Desert because it receives direct sunlight more often than most places and doesn't have cloud cover solar panels create a lot more energy the problem came moving the energy to a populated area but I thought if instead of transporting the energy you divert it to a Hydrogen plant on the coast that uses sea water to make Hydrogen, then put that Hydrogen into ships that have Hydrogen power cells you could then move it to anyplace in the world. As mentioned in this video another problem is cooling the Hydrogen to get it into a liquid but there is another solution there is a substance called Hydride that acts as a substrate the Hydrogen particles fit tightly into the holes in Hydride like a sponge it stores more Hydrogen in less space than when it is cooled into a liquid then to release the Hydrogen you heat the container the Hydride expands and it releases the Hydrogen. The problem is Hydride is hard to make so I'm not sure if this solution would work on a large scale but my idea could make Hydrogen a lot more cost effective environmentally clean to produce and easier to store for transport.

Reminds me of part of the story in the anime Ghost In The Shell where Japan developed the "Japanese Miracle". The process neutralized the most harmful forms of nuclear radiation and was used world wide in the story.

The same HTGR Loss of Coolant accident was performed at Hanford, WA & produced the same outcome, no Fuel Element damage. But this was near 3 Mile Island & interest in nuclear power wained. This is exciting and a boom for both nuclear and hydrogen production!!! Thanks!

I was familiar with Pink hydrogen (nuclear electric). I hadn't realised there was a red (nuclear thermal) variant too. Interesting. PWRs are only about 25% efficient so you get 3 times as much heat out as you do electricity. Not sure what the HTTR numbers are but I presume it's similar. What is the efficiency of the IS plant? i.e is Red hydrogen going to be any cheaper than Pink? edit: answering my own question, it seems that the process is about 50% efficient. So overall this is more than twice as efficient as doing electrolysis with thermal plant electrity (nuclear or fossil). But it's less efficient than hydrolysis itself (70%), so it's not clear that it's better than using hydro/solar/wind (all of which are usually cheaper than nuclear).

Japan has always been able to leverage public-private partnerships like high speed rail, with their massive domestic consumer market to get developing technologies to become the standard, like CDs, not to mention at times the battle of the standards itself consisting of mainly Japanese competitors like VHS/beta or BR/HDDVD, or at worst up and running like the costly to develop hybrid tech in the Prius.

The HTGR running at around 800C is the one from China's designs which uses a Pebble Bed compared to Japan's prismatic block design. Also as for the reactor restarts, that's already underway as per Kishida's notes just in recent months. The plan is to have around 10 reactors running by Winter and move that to around 20+ by Summer, they also extended the operating lifetimes for these reactors (60 years from 40) after they are deemed safe for restart.

What about THORIUM reactors. To my knowledge this would be the best way forward for a variety of reasons. Mainly no risk of meltdown and no radioactive waste byproduct.

_The TRIGA was developed to be a reactor that, in the words of Edward Teller, "could be given to a bunch of high school children to play with without any fear that they would get hurt."_ _Teller headed a group of young nuclear physicists in San Diego in the summer of 1956 to design an inherently safe reactor which could not, by its design, suffer from a meltdown. The design was largely the suggestion of Freeman Dyson._ TRIGA has been used in 24 different countries, often by undergraduates, and there's never been a serious accident that I've heard about. It spikes, very briefly, to 64 MWe. I'd hardly call it a toy, but not even undergraduates can screw it up. I mention this because Dyson was a proponent of high temperature gas reactors as far back as the 1950s, when he was employed by General Atomic. Dyson considered gas-cooled to be intrinsically safe, and water-cooled reactors to be intrinsically unsafe (though ideally suited for submarines, where small matters, and where your cooling reservoir is the entire ocean).

Conventional fission nuclear reactors are not prone to thermal runaway unless there is a cooling failure (3 Mile Island) or back up power failure (Fukishima). The explosions at Fukishima were due to Hydrogen gas build up due to lack of cooling water pumps operation. The explosions were not nuclear explosions, in fact there has never been a nuclear explosion at any nuclear power plant since the uranium is not enriched enough to cause a nuclear explosion.

This video earned my sub. Great video. My experiences with EV tech is EVs are great for light weight things like commuter cars and bikes. The problem is when you do heavy work. There is a great video comparing the Ford F250 (combustion engine) VS the F250 Lightning (EV). They both towed a trailer with a car on it on the same road at the same time with the same exact trailer and two classic cars that were identical. The Lightning only made it HALF WAY through the challenge before needing to be recharged while the regular F250 had plenty of fuel left to finish the trip and drive back. The take away was "EV trucks are great as long as you don't do Truck things". I believe Hydrogen will be for heavy duty applications while batteries will be for light duty. Which is perfectly fine. I rather have competition in tech making things perform better, reducing costa, and pushing each tech to innovate.

The main issue is it’s probably never going to heat your home or power your car which is what advocates keep touting.

12:04 That's not a scheme of the S-I cycle, but of a pool-type sodium cooled reactor. Regarding hydrogen, even if it looses to batteries for cars and trucks, it can be used as a source material for other fuels like ammonia, methane or higher chain hydrocarbons, the trick is in sourcing the Hydrogen cheap enough and having a high quality heat source because most of those reactions need high temperature. With nuclear you have both, on site. With just water and air, a nuclear powerplant can produce tons of chemicals that are crucial for our civilization, on high and constant demand and that today we source from methane-sourced hydrogen; like ammonia, nitric acid and ammonium nitrate. The issue of the demand curve that require grid storage (large banks of batteries or pump hydro) dissapears if you switch the output of the powerplant to those secundary processes when the demand of electricity falls. That problem solves itself the larger the proportion of nuclear you use. Nuclear is really a no brainer. And unfortunetely, once again we have to hear the old waste non-argument. There are many ways to reprocess spent fuel, but most countries don't reprocess waste because there's no need to. New uranium from the mine is not crazy expensive in the very limited amounts needed and storing another decade of spent fuel is really, really cheap, so obviously nobody bothers to...and keep kicking the can down the road is politically acceptable. Yes Triso fuel is more difficult to reprocess, precisely because is designed to be indestructuble. Storing it is still an option, we are talking VERY small amounts of the stuff. The 90.000 tons of spent fuel the USA have accumulated after 60 years producing 20% of it's electricity with nuclear, sounds like a lot, but is just a cube 18 meters on the side, and 96% of it is just Uranium. Storing all the nuclear waste of a 100% nuclear powered human civilization, without reprocessing anything and without improving the fuel cycle or the reactors (because LWRs burn 0.5% of the available energy, it's not a high bar to jump) for the next 1000 years would be less than ideal, and pretty lazy, BUT IT IS STILL AN OPTION.

I see actual hydrocarbon synthesis as the most likely way that any carbon free hydrogen actually makes it into the fuel supply (and yes it's carbon neutral because we will just use carbon already on the Earths surface, the key is to not take carbon out of the ground), we can add carbon to hydrogen easily and basically retain all the energy already used to make the hydrogen essentially turning a difficult dangerous gas into a convenient and safe liquid, it's even actually LIGHTER, because we do not have any hydrogen storage solution which has a parasitic mass less then the carbon has. Not to mention we can use our existing fuel infastructure and engines, replacing every airplane on Earth is kind of a big hurdle ya know. As for grids I think your overlooking that chemical synthesis infastructure is not designed for nor economical to run intermittently. The output of chemical synthesis can be stockpiled easily, we already stockpile huge volumes of hydrocarbons on a yearly cycle building up stockpiles for winter for example, they are the best way to store energy over durations of many months cause you just need a tank and their is zero loss. I think it's far more likely that we just turn on reserve power plants to burn fuels for intermittency gaps rather then try to shutdown synthesis, though like all industrial processes their shutdown would be appropriate in extreame situations.

So if humanity decides to go all in on nuclear energy, the market will decide how much of the waste will be recycled. If the answer is none, will there be a waste problem or not? The DOE designated the Columbia River basin as a national sacrifice zone after buried waste at Hanford was discovered to be leaking into the river. As always, the cheapest solution became policy. I don't think nuclear energy solves human short sightedness or stupid decision making.

Please take a look at the known deposits of Helium (which seems to be the inert gas required for this process) ?

I love this kind of content on green house gases and global warming. Please can you make more of these contents.

The production of hydrogen is one non-trivial challenge. Transporting hydrogen is another non-trivial challenge. So, *if* this method actually does produce "red hydrogen" - transporting it to where it needs to be used, remains as a huge challenge. Plus - *constructing* a "red hydrogen" nuclear plant is *far* from being carbon free.
