@hypehuman3 жыл бұрын
Totally agree. Joe's method makes the efficiency difference between Hydrogen and Battery look worse than it really is. His numbers of 42% and 80% make it look like Hydrogen is only about 52% as efficient as battery (42% ÷ 80%). But in fact, if you calculate it properly, you end up with about 50% for Hydrogen and about 81% for Battery, which means Hydrogen would be about 61% as efficient as Battery. If you have two processes one after another that each have a 90% energy loss, you don't end up with negative energy at the end (Joe would have calculated -80% total efficiency). Rather, you end up with 1% total efficiency, since the second process takes off 90% of the 10% remaining from the previous step, meaning the second step only subtracts 9% of the total efficiency. The more straightforward way to calculate this is not with the loss, but with the efficiency, in this case 10% efficiency for each step. Then you can just multiply them to get the total efficiency: 10% × 10% = 1%. So back to the cars. For example, the Electric Motor has a loss of 4%, meaning that it's 96% efficient (100% - 4% = 96%). So for Hydrogen it's 96% × 94% × 92% × 60% ≈ 50%, and for Battery it's 96% × 94% × 92% × 98% ≈ 81%. Also notice that you can get the relative efficiency of 61% more easily by ignoring the first three steps, since they're the same for both. So 60% ÷ 98% ≈ 61%.

Joe, LOVE your channel and its content. 15 years ago as an advisor to local government I tried to implement Fuel cell vehicles for a small municipality in Alaska. The grid there is ran by small waterfall hydro-electric plants...near zero recurring cost and near zero emissions!! (outside of construction). Also of note; Alaska and the western part of our continent is lined with Volcanoes useful for geothermal energy production with near zero emission and recurring cost, GREAT for producing Hydrogen!. Our calculations showed enough geothermal energy (beyond development)to run the entire "hydrogen economy" without any burden on the current system. I and the committee were told behind closed doors that 'No part of this will be subsidized or funded by the government as it is competing directly with the interests of our campaign funders" ! It was a major lesson in the realities of adult life. Sadly, the government invested in 'Bio-fuel' burning wood chips and in Big-oil. Hard to compete with Big-oil when the government offers strong subsidies, tax breaks and incentives to 'big-oil' while excluding clean energy tech. We tried to work with Icelandic New Energy with their extensive fuel cell expertise. Not sure how to proceed without support, we were told to drop the projects.

My wife and I live in the Denver area. When we are driving around town, an EV works great, as far as Colorado Springs or Fort Collins for the day, no problem, we could recharge the car before heading back home. But we regularly drive to Utah, New Mexico, and Wyoming camping and pulling a small trailer (17' long, 3300 lbs loaded), then the EV doesn't work at all. Heading west of Denver you have to go over multiple mountain passes, and pulling the trailer, and you need a lot of power, and you need to be able to refuel quickly to keep moving. I don't believe the coming EV pickup trucks will work either, because once I drain the batteries getting up the first mountain pass, I will have to recharge, to make it up the second mountain pass, then charge up again to drive out to where-ever I am going - I may have to stop 3-4 times to recharge, with a large battery pack that could add up to hours of extra travel time, maybe half a day for what normally takes 6 hours with the gas SUV pulling the trailer. Seems like this would be more of an issue for people in the western US where cities are further apart and distances driven might be bigger than in the eastern US and where people do a lot of outdoor activities in areas where there aren't necessarily hotels easily available. Or am I underestimating the capabilities of the coming EV trucks? Seems like a fuel cell truck could do the job though. Thanks for the video, I really enjoyed it!

Sure you can! Take the example of someone trying to build a solar-powered go-kart with a shop vac motor: Solar panels are ~22% percent efficient, which represents an energy loss of 78 percent, and the universal motors that are used in shop vacuums are about 60% efficient, which represents a loss there of 40 percent. You take 78% + 40% to get a total efficiency of -118%, which means that energy from the sun is actually *destroyed* in order for the solar go-kart to do no work. Mathematically, we can prove that with enough solar panel + shop vac motors, we can reduce the power of the sun to prevent global warming. Hope that helps!

There are a few more problems with hydrogen that few people ever bring up. First is that hydrogen is the smallest atom and as such very hard to contain. In other words it's extremely prone to leaks. It leaks at every fitting and it's so small it will in fact leak through the walls of a steel tank! OK OK the amount that seeps through the tank walls would be incredibly small, BUT, the problem is that it causes hydrogen embrittlement which affects pretty much everything and will eventually compromise the tank's structural integrity. So, now lets talk about high pressure tanks and structural integrity. 780-BAR (atmospheres) is over 11,000 psi. 780-bar is an incredible amount of pressure and introduces a lot of stress on a tank, and all corresponding equipment such as compressors, pipes,etc.. On top of that you have "hydrogen embrittlement". Now I'm no expert on hydrogen tanks but I can tell you about scuba tanks (200 bar - 3000 psi). At a quarter the pressure they can be and are, if not handled/used properly, extremely dangerous. Hydrostatic testing is required every five years. This test must be conducted by a certified technician and essentially determines whether the tank is structurally sound and will not burst under pressure. By DOT regulations they can only get re-certified two times for a 15 year total life span. I would surmise that with hydrogen tanks, the incredible pressures, and its embrittlement problem that the life span would be much less. Hydrogen embrittlement doesn't just affect the high pressure tank, (my primary concern) it affects everything it contacts. Second biggest concern here is the regulator. A 780 BAR regulator isn't cheap and it will be degraded over time, and even faster because of embrittlement. What problems will that create? Everything about hydrogen fuel cell vehicles and its corresponding infrastructure is more complex and complexity makes things more expensive, prone to failures, and costly to repair. And for those reasons I'm out.
@martinwinlow3 жыл бұрын
And then there's the problem that a parked H2-powered vehicle would lose 50% of it H2 in a week. Then it burns with an invisible flame. Then there's the fact that the range proportions of air to H2 that makes an explosive mixture is 10 times wider than that for any other common flammable gas (and petrol vapour) so a leak is much more likely to ignite. 98% of H2 is currently made from natural gas (yep... a fossil fuel). Making it from electrolysing water can be done but at woeful efficiency compared with just putting it in a battery... and you need pure water to electrolyse, hardly something that we have in abundance in much of the world. The list is endless - and the whole idea, daft.

@ShaunDoesMusic Shaun - I'd stick to music, mate! Sorry, but your argument holds no water (what would hospitals do with H2?!) The 'minor' alterations to use H2 instead of ... what?... are not small at all, you still have to install infrastructure (at vast expense), you still have to make the H2 by steam reforming natural gas (so its basically still a fossil-fuel) or electrolysis - and both processes use so much electricity it ends up being a hugely inefficient and wasteful process. On top of all that doing the same by using simple and cheap batteries is a vastly more practical, sensible, efficient and cost-effective route.

So that we can throw away 2/3 of the clean energy used to make the H2 (and then convert it back to electricity again) rather than just store it in batteries or pumped storage facilities (and other similar systems) using technology and products off the shelf *right now* at 1/5 - 1/10 the cost? ...And using an infrastructure that is 95% already in place (the national grid)?

A small correction for you, you don't add/subtract percentages together, you multiply them to get the correct result. For example if you add (subtract) 50% and 50% you get 0 (0.5 - 0.5 = 0), but in reality it is 25% (0.5 * 0.5 = 0.25). So the corrected percentages would be *33.97%* efficiency for Hydrogen electric and *77.29%* efficiency for battery electric. For gas I calculated the efficiency at 14.69% (on this one we seem to be in agreement xD).

@Mr Cabot Though many of your points are just plain wrong, there are several nuclear power plants currently operating that use salt, not fresh, water, for example, the biggest problem is you offer no effective alternative. Solar simply isn't economically viable and will likely never be, it simply doesn't effectively scale like other forms of power production and it can't be reliably and consistently produced. Solar is a waste of money that would be better used for almost any other form of power generation (with the possible exception of wind, another horribly inefficient and unreliable power source). Solar also relies on rare earth metals, which are no more common in the earth's crust than uranium, but are needed in far greater quantities for solar energy production than uranium for fission energy production. So-called 'renewables' (with the exception of hydroelectric) are a fool's errand. If you want a real solution to energy production, deregulate nuclear and indemnify nuclear power producers from liability for damages that happen due to events outside their control, we'll see electricity prices fall by an order of magnitude, the economic benefit of which would more than make up for the occasional loss of containment; and, despite all the fear-mongering about radiation, it's not nearly as dangerous as people want to claim. The only real challenger to deregulated nuclear power would be natural gas, which being almost free and enjoying exceedingly low transportation costs due to the nation-wide pipeline network, will remain an attractive alternative for centuries to come.

We have a slight edge over Russia today, but things would look a lot brighter if we had more reserves and if we had our missiles outfitted with their maximum number of warheads. But I think you made it clear where you're coming from, you're just afraid of nuclear war and are transferring this irrational fear into an even more irrational fear of nuclear power.

and many other errors with efficiencies and data: List of all the things he is wrong: 1-Fuel cells vehicles are also EV, to difference fuel cell from batteries you should use FCEV or BEV. 2-The extra range is not much about the weight (but it helps), is about cost! To double the range with batteries you need to double the amount of batteries which doubles the cost, with fuel cells you just need to increase the tank diameter by 25%. 3-The power from the fuel cell goes directly to the engine most of the time, the battery is very small and it is almost always at full, it is used to keep systems on or in standby. 4-Today the energy of compression is 12%, but now there are new methods that compress hydrogen by electrochemical compression which is more silent, it takes way less space, and more efficient 8% for 700 bar. 5-Is not about efficiency, is about cost! And here's the best benefit of hydrogen, because it could be used to balance the grid using just intermittent sources like solar and wind, with over production and splitting water with all the excess and injecting all that h2 to the natural gas grid, that h2 can be extracted pure in any point of the net with simple filters and be used in all the apps which batteries are not good like (trucks, ships, airplanes, or any utility vehicle), solving the co2 problem in those 2 energy sectors in which batteries and clean sources cant by their own. You can make hydrogen when the electricity cost is cheap, even negative. So some days you would be almost doing hydrogen for free, batteries can not take advantage of those times because they can only store energy over 4 hours in a cost efficient way, hydrogen can store power over months. 6- When hydrogen infrastructure and devices will start to cover more applications, it means anyone would be able to make hydrogen in their own houses, they would be even able to inject hydrogen into the natural gas grid and get paid by that, the same as we do with the power grid from solar panels. 7- Electrolysis efficiency today is at 83% (with 20 bar compression) or 90% without compression, and you can achieve up to 100% with the new reversible solid oxide fuel cells in development, because they use the waste heat from the fuel cell mode to reduce the amount of electricity needed for the electrolysis mode, no need for platinum. 8- Why a FCEV would have higher loss in the motor and in the inverter vs a BEV?? Have you lost your mind?? 9- It does not matter if the power source is clean or not, we have to start from somewhere and batteries and hydrogen helps to increase the share of solar and wind into the power grid. 10- The cost of gasoline is the same than hydrogen, it requires only 5 kg of hydrogen to match the range of a gasoline vehicle. In addition if hydrogen is used to balance the excess of power, then it would become much cheaper, because today there is no cheaper energy source than solar and wind. 11- What is the future for hydrogen?? you even bother to make a research?? Take a look to China, Japan, Australia, germany, england wants to start, and many other countries.. All are starting with small projects of hydrogen production and injecting the h2 into the natural gas grid. China has prepare millions of fuel cell buses and trucks for 2021. About cars.. for city cars, BEV are more reasonable, for vehicles that requires higher range or fast recharge, then FCEV are more reasonable. Is not a competence.. Both technologies help, both full fill different roles.

You can't produce hydrogen with solar panels right at the filling station, you'd need an absolutely ENORMOUS area of solar panels to keep up with demand and to cover the inefficiency of hydrogen production and use. HFCVs are TERRIBLE performers, the Mirai has less power than most economy cars and is so heavy that it ends up being much slower than most economy cars.

I think hydrogen vehicles will end up taking over the shipping industry and mass transportation due to very fast refuelling.

My big problem is with the initial premise: that we must have personal transportation vehicles for everything. Automobiles and their kin have been around for so long that we now take them for granted, forgetting that there used to be a time before them not too long ago, when you had to walk, bicycle or take some form of animal or animal-drawn box from place to place. We’ve actually structured entire living situations around automobiles, especially here in the USA, like suburbia, shopping malls, and the like. There are many places in larger European cities where an automobile is unnecessary for most of the things you do because 1. They have very good public transportation infrastructures and 2. Their cities are more “walkable,” meaning you need not travel far for most of your needs. Perhaps the best, long-term solution is to move away from personal vehicles and our suburbia model, which is really nothing more than a caricature of “country living,” and instead build more walkable areas with public transportation, especially for long distances, so that automobiles are not as necessary.

You are correct but I also think people like their own personal space and if they can afford it that is why in general they go for cars.

Self driving cars still can't do that. Where I live life would be very inconvenient without a car but if I lived in central London I would walk / use public transport and not have a car.

In that case it would be summed as it was all normalized off of a single bench mark mass of energy

I think one thing was missed here: Hydrogen can be produced in "off-periods" - by this i mean that windturbines produce energy when there is wind, no matter if there is demand or not.. (and yes i know that there are strategies and methods to handle these) - but one way of handling this is to store the extra energy generated in these periods as hydrogen, and then use it later. Basically making the hydrogen the battery in which we store the excess energy.
@theelectricmonk39094 жыл бұрын
Totally agree - and IMHO this is how wind farms (which are currently hooked directly to the grid & have to switch themselves out if demand is low, not to mention the relative complexity of synching them to the grid) SHOULD work. Sure, generate directly to the grid if the demand is there; but if not, any excess = produce & store H2, which can then be burnt (or put through a huge fuel cell) to generate power if there's more demand than there is wind.

A few things that could change this are: - battery tech hits a major road block and doesn't improve beyond current levels - affordable home hydrogen production, just hook up to the tap and grid - improvements in hydrogen production tech I can see a world where performance cars use HFCs and daily drivers use batteries. Even without those hypotheticals, I can see hydrogen tech and infrastructure being used for long haul trucking, aviation, or any other area where distance/weight are major concerns.

Electricity is not nearly as ubiquitous and accessible as proponents of electic cars make out. I am a huge fan of electric cars, but a lot of videos like this one are made with North America in mind, where the majority of people have at least a driveway, if not a garage, where they park their car. In Europe most people park on the street, and often not anywhere close to where they live. I live in an apartment complex with parking out front just off the road, and further parking in behind the buildings. Even if I manage to get a spot out front of my flat, I would need to dangle an extension cord out the window, across the walkway to the entrance of the building, and over some bushes. If I have to park out back my car is 150 meters away from my flat, and surrounded by storage garages. In Europe creating the sort of infrastructure needed to charge electric cars 'at home' would require an enormous investment on the part of homeowners, local councils, landlords, etc. It's a real problem here for electric cars.

Three notes: 1. Steam reforming of methane does release CO2, but Methane is a terrible greenhouse gas, so if you already have it and can't store it, it's actually greener to burn it than to let it escape into the atmosphere. Methane is one of the byproducts of some forms of composting, so it would be entirely reasonable for industrial composting to collect the methane and either store it as fuel, burn it to produce electricity, or steam reform it to produce Hydrogen. 2. Hydrogen is incredibly hard to store, especially at high pressures. The atoms literally leak straight through thick steel tanks. This would be a significant factor in the efficiency of transportation and use of hydrogen as a fuel for cars. IMO this is the single biggest reason not to pursue HFC technology for mobile applications. 3. If you just want to improve on gasoline with a technology that has higher efficiency and lower emissions, Methane is a much better choice than hydrogen. Methane is the cleanest hydrocarbon because it has a 4:1 Hydrogen to Carbon ratio, so you are mostly burning hydrogen, with very little carbon being burned (Octane is 2.25:1 Hydrogen). Methane is much much easier to store than Hydrogen giving equivalent range at much lower pressures lowering the weight of the tanks, and the danger involved in fueling it up. Methane fuel cells do exist and could provide a similar convenient packaging for electric propulsion as HFCs can. But IMO the biggest benefit is that for roughly ~$1000 you can retrofit existing vehicles to run on methane, allowing people to go green without waiting for all the used cars on the market to be replaced. IMO if we want to pursue a stepping stone technology to be used in places where EVs currently fall short, Methane is the way to go.

Building on this is what we're beginning to see with the new EV models. ~100kW is great for a car. However, for a truck, SUV, or something that's larger/less efficient were seeing batteries that are significantly larger. The announcement of the Tesla Semi brought with it a 1,000kW battery and touted the ability to charge to 80% in 30 minutes. This places a massive load on the power grid. 1 truck would utilize a 600V 2000A 3-phase service. Charging multiple trucks? The grid wasn't designed around this. For cars EVs are pretty sweet. But when you're talking about charging rate of 1.6MW/h you're introducing several issues that are all interrelated. 1. Heat - 1.6MW is a lot of power. 2. Power management - getting it wrong on a little Tesla or even a phone isn't a good day, this is significantly larger. 3. Grid supply and availability - your fleets needs may not be Sympatico with the local infrastructure 4. Heat - management and mitigation will be very important 5. Logistics externally - they don't make 2000A cords 6. Logistics internally - since Superconductors aren't a thing your internal charging system needs to be sufficient for charging at 1.6MW of input. 7. Weight - see above 8. Heat

Steam methane reforming needs very high energy consumption due to very endothermic nature of the reaction. Not to mention the steam production which is also energy-intensive and requires boiler-grade water. So it would've failed in terms of life cycle assessment. And ever heard of hydrogen storage in form of ammonia? Ammonia is easier to store than hydrogen and methane and conversion process of hydrogen into it is also a mature process (the Haber-Bosch process). Moreover, the reaction is spontaneous (it has negative Gibbs energy), thus allowing robust storage of intermittent electricity from renewables as well.

Yes, I think methane has a chance as well. We see many cars on CNG these days and LNG is also growing rapidly for long haul transport in Europe. We can expect these to hybridize, combining CNG/LNG with a battery. The next step is to add a fuel cell. This will allow the gas engine to be downsized or even eliminated. I think what we see is more of an evolution than a revolution. EVs right now are just a niche product. The major change we see now is that traditional gasoline cars are getting replaced by mild hybrids. The traditional car is gone and most people haven't even noticed. Hybridization is increasing rapidly and cars are gradually getting electrified. At one point EVs will have a major share in the car market, but not in the near future.

When comparing the two, you completely forgot the efficiency loss when creating electricity for your EV. You seem to assume that to be 100% efficient. Coal plants run at horrible efficiency levels and even cleaner energy such as solar power wastes a lot in the conversion. For a fair comparison you should include that loss as well. Or at least some average. And let’s not forget the vast amount of environmental damage lithium ion batteries incur because of the mining of these precious metals and the fact that the batteries only have a quite limited lifespan and need to be replaced regularly. But more importantly, how can you miss one of the most important advantages of hydrogen: creating it when overproducing electricity? Off shore wind parks can create vast amounts of hydrogen when the grid demand is low. This is perfectly useable as a fuel. It feels as if you had your mind already set on EV, the balance in this video is a bit off.

Well since we are also adding the extraction and transportation of resources to the inefficiency, wouldn't it make sense to then also take depreciation into account? Lithium batteries do not grow on trees (nor do they tend to be recycled), yet from the calculations it seems like lithium batteries do in fact grow on trees and then poof out of existance when empty (which you won't reach because the battery will be replaced long before it reaches zero charge). While for gas he takes drilling and refining into the efficiency calculation. And for hydrogen fuel cells, as far as I know they still haven't solved the matter of hydrogen embrittlement beyond saying "we're on it, I wouldn't worry too much". Which would cause parts to need to be replaced far more frequently because it is a pretty huge issue to have your fuel alter the mechanical properties of parts.
