A few weeks ago Wheelhouse made an episode about how Hydrogen cars were supposed to be the future of automobiles. And in that episode Nolan made a pretty good economic argument for why they failed. An argument that everyone’s favorite billionaire, Elon Musket, might agree with. But like all things car related, I get curious about the engineering side of things. Outside of politics, why couldn’t the car of the future be hydrogen powered? Well today on B2B we’re gonna take a look at hydrogen-fueled tech, and explain why Elon Musk might just be wrong about hydrogen cars.

I have been saying this for years. Thanks so much for popularizing it. Near the end, you pointed out a key benefit; the output at the end of the chain is the cleanest, pure H2O possible (though spitting it out wasn't exactly a ringing endorsement). That has environmental implications on a global scale if Hydrogen is adopted. It can also supplement and displace fossil fuel-based power grid generation, using a portion of the renewables mix - along with methane (NG) during the transition - to derive Hydrogen. I have deep concerns about the environmental impact of adopting purely electric cars with LI batteries on a global scale, and that is what's taking place. At least they last an increasing number of cycles/years, and are largely recyclable, but it is an expensive process in every respect. I'll put it this way: develop energy technologies utilizing the most fundamental and plentiful element in the universe, or mine rare earth minerals and create vastly more environmental degradation utilizing a finite resource.

Hydrogen fuel cells could be THE chief method of solving the demand vs supply problem of renewables. Renewables are capable of producing thousands of times more power than the entire planet needs with extremely low environmental impact, the issue is getting that power from the times and places of plenty, to where it's needed. Unless magical graphene batteries suddenly take off or something, or we develop a superconductor that can be used in power lines, currently the largest problem holding back full renewable adoption is storage. Using the excess of power during the day to produce hydrogen is analogous to charging a battery. Conversion efficiencies basically don't matter when all that power is free, and there losses associated with shipping hydrogen across the planet are far lower compared to stringing power lines everywhere.

Love your guys’ content, I might disagree on this one though, with something like 3 billion internal combustion engines on the planet, replacing them all is a massive undertaking. The use of hydrogen as a fuel for combustion in the retrofit role for carbon based fuels as opposed to fuel cells in electric motors has opens some doors with H storage in nanotechnology that has been implemented already. It’d be awesome if y’all covered nano fuel storage of H and it’s use in retrofitted internal combustion engines with spark injector tech. Dude in Phoenix/ Tempe has had it working for years but hooked up with a guy to finance and got their HQ raided by Gov’t for financing but tech is sound, and displacing entrenched hydrocarbon monies may have had something to do with it.

It's kind of interesting looking at this. Here in NZ we are a pretty linear country - our main highways are basically in a line. Couple that with our high availability of renewable energy (mostly hydro) and we're situated pretty well for hydrogen - which has better fueling times and currently seems to have better range. There's companies looking at setting up fueling stations for trucks (as in shipping/cargo trucks). A lot of these will be able to produce hydrogen on site. The interesting thing? Current hydrogen trucks would get the same range as their petrol counterparts (around 600km or so here) but would also have the advantage of instant torque from electric propulsion *without* sacrificing the quick fueling times of petrol!

Literally the main thing that you missed which is the entire reason Elon said Hydrogen fuel is useless, is the range. Its lack of density means you would either need to have it at cryogenic temperatures to get anywhere, which would take up space to have something to make it cryogenic, or you refuel every 15 minutes because you literally can't get enough space to put it in. If you do make enough space, you're weighing the car down immensely with the amount of storage required, thus negating the benefits and lowering over DeltaV.

The only thing that may be a problem for Hydrogen is that the best electrolyser at the moment uses around 50kwh of electricity to produce 1 Litre of hydrogen. Even if someone creates an electrolyser that is 100% efficient it will still require about 37 or 39kwh of electricity to produce 1 Litre of hydrogen. The maximum potential energy output per Litre of Hydrogen is about 33kwh. This is prior to transportation and compressing the hydrogen. The amount of energy wasted in the process will see most utility scale renewable suppliers just feed their electricity into the grid rather than produce hydrogen, as it is more profitable. It could become a supply issue in the future, especially with the development of solid state batteries. Not to mention the support of most governments around the world for investment in renewable energy. Hydrogen is great for the auto industry, and their car designs, but not good for renewable utility suppliers, who will eventually control the market as they control the sale of the renewable electricity. As demand in the gird for renewable electricity increases, the less likely it is for a renewable energy suppliers to use the electricity to create hydrogen.

The performance in hydrogen vehicles comes from the size/capacity of the on board battery. Fuel cells in hydrogen vehicles provide charge to the battery, but the motor is power from the battery. There are a few reasons there a batteries in hydrogen vehicle: 1. Fuel cells have a very slow response in terms of change in power output, so batteries are used to compensate for that. 2. Using a battery reduces the size of the required fuel cell stack thus reducing price (fuel cells are very expensive) 3. Using an electric drive-train gives you a benefit of regenerative braking, and storing the energy from regenerative braking is impractical using fuel cells, so that task is given to the battery.

One law in chemistry is that a reaction will go to the most stable form (acids react to be more stable, like HCl + NaOH will turn into water and salt) so for electrolysis to be made you need to put more energy into the system to dissociate the bond that H and O have. So why would you use more energy to make a system work? It is better to use the energy to charge your batteries in the first time. If you want to know how many cows you have, count heads, don't count legs and divide by 4.

HFC cars are actually evs with their small battery charged by the fuel cell. The fuel cell cannot provide the instantaneous current needed for acceleration. These are complex cars with the tiny drive battery being constantly thrashed, with deep discharge. The drive battery will probably only last 100k kms. Then the fuel cell membrane will likely also need replacing in 100k kms and the other additional maintence required that pure evs do not have. A HFC car will be expensive to maintain, and likely be a throw away after 100k kms. In addtion, 3-5x more renewable electricity needs to be generated to provide the same power at the wheels for a HCF car than is needed to provide the same power at the wheels for a pure ev. And packaging is also an issue for HFC cars - all those systems need to go somewhere in the car. Then there is the infrastructure issue.

Currently the EVs are having 95% efficiency and their energy density is 200 wh/kg at the most, and then hydrogen with 60% efficiency with the current technology, and I'm saying this after deducting transportation, cost of electrolysis. The energy density of hydrogen is - 33000 w/h, and if take 60% of it which 19800 w/h. U see hydrogen is a clear fkin winner. Compare 200 w/h with 19800 w/h and even in future with Solid state or blade battery it will maximum go 400 w/h ( optimistic claim). Take the weight too, which is 3x then a hydrogen car, even with reducing weights in future, it still will be 2x. Not to see how much efficiency loss in EVs are there and charging time and finally cost.

The electrolysis process is currently too expensive as energy intensive. The tech is sound but right now the economics just don’t work. We already have an electric infrastructure that can be added to and expanded. A pressurised hydrogen solution on mass is a long way off if at all.

Storage is an issue, but one I think we could solve. The real problem is the energy required for electrolysis. It starts out at a third the efficiency of Bev before you even start to 'burn' it.

@@morosis82 I have to disagree. The efficiency problem may be less of an issue as excess energy from the grid can be used.. Not a total solution, but a problem we can work with.. The storage problem is much larger than many people think (no pun intended).. For hydrogen to even come close to the energy density of hydrocarbon fuels it has to be under pressures so high, you're basicaly driving around with huge bombs in your car. Then there is the weight of the containments for this super high pressure bombs.. It's a serious issue..

@@jacoblemen I think you underestimate the amount of energy required. The calculation for electric cars in the US is to add roughly a third again to the output capacity over the next decade or so (not actually a big deal, it's been expanding faster than that in recent decades anyway), hydrogen would require triple that and then some.

@@devinbender8428 who gives a damn when most electricity comes from unclean sources. You can make hydrogen literally anywhere and transport it. Nuclear reactors, hydro dams and wind farms can make hydrogen at all times. In fact this solves one of the biggest problems with wind farms and solar farms, which is that much of their electricity is wasted as it cannot be stored unless you build stupidly large batteries this is without considering how batteries are utterly useless for long range travel, good luck getting battery powered semi trucks, trains or aircraft

In a gasoline engine 87% of the fuel (the carbon) is mixed with oxygen creating a non combustible compound called carbon dioxide, It produces no power. The other 13% (the hydrogen) combines with oxygen and turns into a super heated dry steam when ignited. So internal combustion engines are basically hydrogen powered steam engines. I hope this doesn't scare the hydrophobic's.

The difference is that when people said E/Vs didn't have the infrastructure, they were mostly wrong because you can charge them at home using the basic infrastructure we all have. The whole supply chain and infrastructure already exist, so people started sticking up chargers in their parking lots, and saw increases in business. This was one of the early benefits of E/Vs that drove interest and investment in them. It is essentially impossible for anyone to use a hydrogen car unless the infrastructure exists, so the industry would really have to go out on a limb to create a very large infrastructure and supply chain just on the assumption that hydrogen cars will win out over electric, which is already succeeding. To some people, I guess it sounds like this should be an easier way to do things because it would be just like gas. The reality is, delivering electricity is far cheaper, easier, and more efficient, and charging times are going down lower and lower.

Because it is nearly impossible to store electricity in a mass scale. We have batteries right? Well they can only store a small amount of what is produced. The power plant for your city is constantly running to meet the current demand. We don’t have the tech to make a battery big enough to store all that energy, it’s why solar power isn’t very good on a mass scale. you can’t store enough electricity to run a city to use at night when there is no sun. Same with wind energy and even dams. So if you could, without hurting the environment, convert that energy to hydrogen to use later it would be a huge victory for renewable resources.

Electrolysis is a fairly simple procedure. If transporting compressed hydrogen is a concern, installing a small electrolysis facility at a gas station wouldn't be too prohibitive. Then the only concern is having pure water and catalysts on hand to keep recharging the hydrogen tank for the ~2 people who need it until the infrastructure and market grows to match/exceed.
