It's This Easy to Charge Your EV With Hydrogen!

"3 phase DC Charging" My head just exploded.

Wut Da?

[@brushlessmotoring]

Roman misspoke. It's DC, no phases. For a grid connection to have a DC fast charger onsite, you bring in 3 phase AC from the grid, and that can take time and money to arrange, whereas this can be deployed immediately. There are diesel versions of this too, the benefit here is emissions.

[@brushlessmotoring]

@@Urgento22 I got some useful nuggets out of it, Roman was more or less asking the right questions, even if he wasn't as technical as maybe you would like, but the GM dude did know his stuff. 14.6kWh per kg of hydrogen, 240kg from a huge tube trailer, 60kW throughput but probably a shortened lifespan on the Fuel Cell as a result - all good info. There are challenges we need to solve in the transition, I don't think hydrogen is the answer pretty much anywhere near ground transportation, but, I'm willing to listen to ideas like this to see where else they might lead. I get the sense vanadium flow batteries might be a better fit here - but I'm less sure on the numbers, I don't know how many MWh you can put on the back of a trailer, cost per kWh, kW sustained output, life span etc. etc. All this talk of renewable hydrogen seems to overlook the massive inefficiency of going through hydrogen as the carrier (66% loss), there are better places to hold that energy, if the hydrogen is grey (made from methane) - which it most likely is, despite the stickers - the for a temporary mobile deployment like this, natural gas / propane / LPG is probably the better choice with a large 100kW genset.

so, the concept is that you make the hydrogen from water using green power. The "hydrogen economy" doesn't involve fossil fuels. (notice the sign behind the GM guy, "operate your trucks on zero emission hydrogen fuel made in the usa". 🙂) Even if you never used it in a vehicle, there's a good reason to make green hydrogen, and that's to store energy for long periods of time. Theoretically, hydrogen could stay in storage for months....let's say you generate it during the day from solar power, and you deliberately made more solar than you thought you would ever need, so at the end of summer you have a ton of hydrogen, and that lasts you through the winter when there's less daylight. Yes, you're sacrificing some energy efficiency, but you gain that long duration capability. Here in California, we generate significantly more solar than we need, but we haven't built enough storage for it to last us through the night. We have the largest battery system in the world, but it's still only 6 GWh; the goal is 53 GWh by 2050, but at the present rate, we'll have that in about seven years. But you don't necessarily want it all in lithium ion batteries, because they can only retain the charge for a certain period of time.

Thousands of times more. 2) the idea of this is if you have a remote site and would rather have some portable power storage that's green. A solar panel would take up a larger area, and this outputs power 24/7. FOR CARS, YES, BATTERIES ARE THE WAY TO GO. NO ONE REASONABLE DISAGREES..... But not every vehicle in the world is a car....and sometimes you need to store large amounts of green energy. H2 is a way to do that. I feel like a lot of you guys think H2 has to be extracted from fossil fuel and that's the only possible way to do it, but you're wrong. It's mainly green power people who are talking about H2, and they're talking about extracting it from water NOT fossil fuel.

For almost 30 years we’ve been going down the wrong road! It’s always been hydrogen!!!! Imagine where we’d be if we’d put all the R&D into going hydrogen instead of electric cars?!?

[@brushlessmotoring]

It's not through lack of trying or investment, its the sheer physics of the problem that hold hydrogen back. It's only use now, is to distract and delay the public from EVs - the goal is not to get you into a hydrogen car, it's to keep you in a gasoline one. Truth be told, the investment in EVs has been lacking, not hydrogen. NASA spent billions in today's money on it, Toyota has sunk their entire reputation and future on it, but it just doesn't work as well as a battery - on every measurable quality - even filling time, when you average out ALL fills and mark charging an EV at work, home or hotel as the 10 seconds it takes to plug in and walk away, vs. the 5 to 10 minutes you spend every 200 miles filling a hydrogen car - and that's assuming no line up or hydrogen shortages. PEM Fuel Cells are an efficiency breakthrough that took us to the moon in late 1960's, auto manufacturers have been trying to make them make sense in a vehicle ever since, but if you want green hydrogen, the losses from the electrolysis and fuel cell combined give you back less than 33% of the electricity you put in, that's why it's so expensive, and will always be at least 3 times as expensive per mile than an EV.

[@AlRoderick]

Toyota has thrown a lot of r&d money at hydrogen, but there's a fundamental economics problem that they aren't going to be able to solve with any amount of technological advances.

[@anydaynow01]

@@AlRoderick The big problem Toyota had that Tesla solved was the filling station problem. Even if they had a system where all you did was hook up a garden hose to a filter in the car and plug it in at home to power an onboard electrolyser to fill up with H2 that would have been a better system. Then there are sealing problems, needing an electrolyte fluid fill for the electrolysis process, changing out said purification (most likely RO filter) and things get very complex very quickly. The battery solution is pretty decent for a commuting appliance, especially with the convenience of home or work charging. Still think the best solution for people who have a place to plug in daily is a PHEV though, at least until we get more battery factories and mines up and running. The generator is underutilized if ever used that much, modern fuels and lubricants are much more stable for longer storage lives, ICE tech has gotten to the point where it rarely has problems (it's usually the electronic gizmos that go wrong in cars these days), and modern batteries can take the abuse of many cycles, at least well past the time people typically keep their cars these days.

So charge your EV with fuel. How novel. Maybe natural gas, diesel or gasoline too? Maybe just start with a vehicle that uses fuel and skip the whole EV part? There are some significant losses with the switching back and forth. The amount of losses, back-end costs and infrastructure that goes into keeping these EVs running is mind boggling.

[@jghall00]

EVs are easy, we have electric most places. It's the power distribution that is problematic. More energy is coming from rural areas with solar and wind. Need more battery storage and high voltage transmission lines.

[@brushlessmotoring]

Actually .... EVs are very cheap to fuel directly from gird connected renewables. Charging stations are cheap as chips to add, and AC chargers are very cheap, an overnight fill is fine for a lot of use cases including the majority daily driving we all do. Don't conflate the complexity and cost of hydrogen with EVs - they have very little to do with each other. You can fill an EV from a Diesel generator if you have to, and that emits less CO2 per mile than a diesel combustion engine does due to the efficiency of the generator and the EV combined. (Bloke in the Australian outback did it as a test). This looks an awful lot like GM trying to avoid writing off their hydrogen costs as a complete loss. Something Toyota will eventually have to do too.

[@kadmow]

@@jghall00 - all the cars plugged into the grid most of the time will be the batteries everybody is looking for - every carpark will have a charge point at every bay at some eutopian point, those don't need to be very fast to recharge for the few miles of typical commute - then the houses can suck down whatever energy they need overnight (if the wind doesn't blow, while the sun doesn't shine) - leaving the next day to rinse and repeat.

What they always fail to tell you is that hydrogen cost more than three time as much for the same distance in electricity. 95% of the worlds hydrogen production is grey hydrogen which is from methane reformation, coincidentally producing large amounts of greenhouse gasses. Not only super cost effective but also great for the environment.

[@brushlessmotoring]

Grey. Blue supposedly captures most of the carbon, but is not successful at scale. Most hydrogen is grey (methane) or black (coal) and emits all it's CO2 into the atmosphere.

Awesome and enlightning information about the market that hydrogen can compete in.

[@georgeh6856]

It seems like it is much more difficult to generate H2 gas than to generate electricity from solar or wind, etc. Splitting water through electrolysis, for example, is very energy intensive. I think that the advantage of hauling H2 instead of a giant battery pack is energy density. But it seems like there may be more loss from doing this than from having a fuel cell vehicle. With this it does the extra step of converting from H2 to electricity, then storing that electricity in the EV's battery, plus the energy to haul the equipment. Sure, fuel cell vehicles have small batteries, but I think that is more to do regenerative braking, etc.

[@WW-wf8tu]

[@lesliefranklin1870]

A vast majority (95%) of hydrogen is currently made by steam reforming of natural gas. This is the cheapest process but it creates CO2, CO, etc. as waste byproducts. The production of hydrogen by electrolysis is much cleaner, but more expensive. Also, water does not want to be split, so this is a very inefficient process. Perhaps the price will come down so this will be the more affordable option. However, we are not there yet.

[@chrisb508]

I wonder if there is a realistic way to produce hydrogen at remote sites using solar or wind and electrolysis. If that were the case, this would have real potential essentially solving the intermittent problem we have with wind and solar. Since about 95% of the hydrogen produced these days is with steam methane reforming, I'm not sure I see the point. Why not just have a generator that runs off propane or natural gas if the total emissions are similar to those resulting from producing the hydrogen? Are there actual plans to expand production of "green" hydrogen?

[@brushlessmotoring]

You make a good point on the propane generator, if the hydrogen is grey (as most is), hydrogen is worse on CO2e per kWh, and propane is a lot easier to handle, and you can bring far more energy onsite in the same space. (Source EIA - US Electrical Generation) Propane 0.97lb per kWh - 439g per kWh. Grey hydrogen, 9 to 12 kg CO2 per kg of H2, at 14.5kWh per kg, 620g to 830g per kWh through a fuel cell. The problem with renewables going via hydrogen is you lose 66% of the input electricity, better to use a battery for multi-day storage, or overbuy on vehicles so you can have some charging while using others - most fleets have surplus vehicles to account for servicing downtime, a mix of wind and solar gives a somewhat consistent supply, and you may get overnight charging which is more useful, wind can break down though, being mechanical.

[@kencotton4645]

I would think it would have great applications for disaster areas, to counter all those naysayers who say you could not charge your car if the grid is down due to a disaster.

[@brushlessmotoring]

Propane gen-sets already fill this need to be honest, and they can sit standby ready for years, unlike pressurized hydrogen. Interestingly, if the hydrogen is grey (made from methane) - and it most likely is - then the CO2 per kWh is lower from direct propane combustion.

Hydrogen is dumb. It leaks. It's the universes smallest molecule and needs to be stored at 400 bar, 400 times atmospheric pressure for cars or this purpose.

It only needs to be a 4% mix with air to be flammable. People who work professionally with hydrogen, are very, very aware of the risk of using hydrogen and this generally scares them. A solar station powered mega battery pack is far more efficient can be truck mounted if needs be and uses the same batteries as vehicles so economics of scale are on your side.
