[@adrianthoroughgood1191]

I think plug in hybrid hydrogen is the only way it makes sense. Most people don't drive long distances everyday. For people who most drive shory distances and sometimes long distances it would be somewhat wasteful to carry around a very heavy battery to give a long range when you mostly don't need it. Having a small light battery big enough to cover normal usage very efficiently and hydrogen to boost range for the occasional long trip could be a good compromise. The poor efficiency of hydrogen doesn't matter so much if you only use it occasionally. The savings in weight and resources from the small battery could outweigh it.

[@BernardLS]

The back ground music was a distraction from the commentary. The outputs include fresh water that will have a limited market when landed and be an oversupply on board a cargo ship, the waste heat might have a use via cogeneration but the hardware and complexity will add cost. Shipping is a 'high volume low cost' business so until H2, at all levels, gets to be higher value than hydrocarbon the industry has little incentive to change.

Most ammonia is synthesized from natural gas. Electrolysis of water takes energy. In fact, it takes about 25% to 30% more energy than you can extract from the hydrogen so produced. Most hydrogen is currently produced by steam reforming natural gas. Hydrogen IS NOT an energy source. Rather it's a (somewhat) convenient way to store energy. As Claude Bai pointed out above, unless and until cheap electricity is made available on a grand scale through nuclear power, hydrogen power will continue to rely on fossil fuel (natural gas) as its source.

Don’t forget thermal hydrogen synths, biological hydrogen synthesis, cost effective energy storage, use surplus energy, batterie weight and long recharge time excludes them in use of polluting sectors like industry, energy storage, aerospace, trucking, shipping, and can be retrofitted into ICE and natural gas pipelines for clean cooking gas. Hell with nuclear we would have the surplus power even if hydrolysis was half as efficient.

it's economical in bigger vehicles, battery electric vehicles give diminishing return after a certain point as the weight of battery increases range increase gets lower and less significant, so in bigger vehicles travelling long distance hydrogen is better fuel, and in cars, not everyone has a garage, majority people in cities live in apartments, and it's not possible for very to go every night or in morning to go to charge vehicle for at least 30 minutes and wait for that time every day, only those who have garage or charging points in their apartment will be fine, which are a very few.

A hydrogen prime mover would be a good use of the fuel, like Hyundai xcient fuel cell trucks. Considering trucks use about 2 litres per 100km

[@engineeringtheweirdguy2103]

whilst they are good use of fuel cells when compared to ICE vehicles there is a lot to realise here. The Xcient only has a 400 miles range fully loaded, whilst the Tesla Semi has a 500 miles range fully load and can accelerate much faster. Ontop of this hydrogen, whilst being gravimetrically very dense, is not volumetrically very dense in application, coupled with the fact that fuel cells are poor at delivering power on demand. That means the Xcient takes up alot of space. In pictures you can see the result of this in verticle height above the wheel wheels and by how long the truck is, which would significantly reduce its turning radius. This also means the Xcient needs a 75kWh battery pack. thats the same size as the battery pack in a Tesla Model 3 Long range. Ontop of that hydrogen fuel cell vehicles dont last very long, the Xcient full cells are only rated to last 100,000 miles an due to hydrogen ebrittlement the fuel tanks themselves are only rated to last 15 years. Tesla's on the other hand, on the road today, their batteries will last 500,000 miles give or take battery size, to 70% health. With the semi having a much larger battery that means it will have longer life still. And lastly it costs significantly more, as much as 20x per mile more for hydrogen vs BEV's. So the Xcient will cost significantly more to operate than something like the Tesla Semi when it is released. But what about charging I hear you say? well most countries, US, EU, Canada and Australia included, have legal limitations to how long a truck driver can go without taking a break. In the US a truck driver is only allowed to drive behind the wheel for 11 hours. And must take at least a 30 minute break, and must do so before completing his 8th hour of driving. Meaning that with 500 miles of range, the Semi would need to pull over for 30 minute break by law before it peaks its maximum range, and 30 minutes is more than enough time to super charge back to full before departing for your remaining 3 hours before you have to call it a day. That means you only need to charge during the times you're now allowed to be driving the vehicle anyway. Ultimately this means that there is no real advantage to fast re-fueling quickly if you're doing 500 miles of range. 400 miles of range however might cause more problem and add wasted time rather than subtract it.

The hydrogen fuel cell is promising but in order for this to work, we have to develop a network of hydrogen stations just like gas stations. This will be costly and time-consuming and moreover hydrogen is more volatile. If we go for battery-powered vehicles we can leverage existing electricity infrastructure.

If we are still burning carbon to produce the hydrogen, then there is no point in adopting hydrogen as the new fuel. If the "greens" think that renewables can supply both the National grid AND (in its spare time) to electrolyze lots of water for the hydrogen economy, they should re-do their calculations. The best hope for hydrogen is an expansion of Nuclear. But let us make sure those nuclear power plants are not pressurized water reactors. Molten salt reactors are theoretically better, safer, cleaner, cheaper. A fraction of the money used for Hinckley Point would see MSRs in production. The British/Canadian company: Moltex already has a variant of the MSR (called the Stable Salt Reactor) under construction in New Brunswick. What is more, it very kindly burns up waste from 80 years of our conventional nuclear industry.

[@zeropride1133]

Not really, making gas produces CO2 on top of producing more when burned in a ICE. Hydrogen no longer produces CO2 when in use making it likely the next gasoline. Until there are billions going into Hydrogen production advances on the CO2 side wont take place.

Would this really be advantages enough to justify adding the most expensive parts from both types of vehicles to make a single vehicle? It would probably cost the future equivalent to $50k in today's money for a car that has the build quality and comfort of a ICE car that is 1/3rd the price. Plus both systems would take up extra space something that would either require a larger vehicle driving costs up or less interior space and the extra weight would effect performance. The only advantages of this system is that you could run it on cheap electricity most of the time using hydrogen for road trips. Such a vehicle worsens some of the biggest disadvantages of both systems and reduces some of the advantages while providing only a moderate benefit that most people would use less than 1% of the time.

[@engineeringtheweirdguy2103]

@@Victor-oy8bj ok. well lets have a look. I'll outline some problems then I will show how they work out in real world examples. sounds good? ok, Firstly, Hydrogen fuel cells dont produce alot of power. Infact the need batteries to adequately accelerate the vehicle. Even then, Hydrogen vehicles are still exceptionally slow. There are some examples of incredibly fast hydrogen vehicles but they have the practicality of Lamborghini aventador being a family car for a soccer mum. They're purpose built machines with no boot, 2 doors and 2 seats. Hydrogen is also incredibly inefficient. to produce Green hydrogen you need grid electricity and water. The same grid that charges BEV's. Hydrogen is very inefficient however, requiring 3-4 times as much grid energy per mile than a BEV. Which means 3-4 times the same emissions. Yes you could run this from renewables but the same can be said for BEV's. The other way, and the cheapest way of making hydrogen is getting it from fossil fuels (hydro-carbons) where you split off the hydrogen and the carbon is released into the atmosphere. This way of making hydrogen actually releases more emissions than if you had just burnt the fuel in the first place. That also means hydrogen will always sit at around 20x more expensive to operate per mile than BEV's. The next problem is that hydrogen, whilst is very gravimetrically energy dense (kWh/kg) is not very volumetrically energy dense (kWh/L). In practical application, the volumetric energy density of hydrogen means that its less than half that batteries. Making vehicles its in fairly impractical in terms of space, especially when you consider it also needs a fuel cell, exhaust system and batteries to boot. For this reason its difficult to get a long range hydrogen vehicle. Typical hydrogen vehicles on the market only offer 20% more range to a tank. Another problem with hydrogen is safety. Whilst they've made a very good effort to make the fuel tanks safe (since your sitting on 160kg of TNT in a Mirai but a hand grenade is only 0.06kg of TNT). They've also protected the tanks by reinforcing the chassis. This reduces your crumple zones and results is lower survivability in a crash compared with similar vehicles. It also has huge implications on weight, with Hydrogen vehicles typically weighing more than their BEV counterparts. Even in trucking, the Hyundai Xcient hydrogen truck weights more than a Tesla Semi but over a ton, and gets 200 miles less range fully loaded. and finally, The lifespan of hydrogen vehicles. Since hydrogen embrittles materials the cars dont last forever. Infact, little know fact about hydrogen cars is that they come off the assembly line with an expiration date printed on the fuel cap limiting the life of the vehicle to only 15 years. The fuels cells themselves only typically last between 150,000 miles to 200,000 miles whilst modern EV batteries are designed to last 500,000 miles to 70% of their original capacity whilst next gen batteries about to begin production in 2022 will last nearly 1.5 million miles to 90% of their original capacity. Making hydrogen a poor lifetime investment.

I may be wrong on this but am sure I have seen this somewhere...take this example... Car#1 Pulls into a H2 station to refuel. 3-5 minutes later drives off. Car#2 Pull in immediately behind on the same pump. Has to wait 30 minutes for the pump to recharge/re-pressurize.

Fuel cells can be rebuilt whereas batteries eventually end up in the landfill. Chemicals in Battery is hazardous to the environment whereas the only liquid in a fuel cell is water. It’s true that hydrogen is less efficient than storing in battery but we have enough sun and solar panel space to make up the inefficiency to a point where it does not matter. There’s more emission release in the process of making batteries than making fuel cells. Fuel cells can be dismantled, cleaned, and refurbished to be use again. Batteries lose storage capacity over time and cannot be refurbished. For these reason in the long run hydrogen is better for the environment.
