Hydrogen fuel cell cars seem great: hydrogen and oxygen in, nothing but water out. But if that hydrogen comes from dirty, carbon-emission spewing power plants, your sustainable car might not be so green after all. #fuelcell #electriccars #emissions

If you’re going to drive a fuel cell car, you need a way to carry around all that hydrogen. Currently, that’s done with big, bullet-proof gas canisters. But metal organic frameworks (MOFs) could someday be more efficient storage solutions. We talked about MOFs in our recent video on extracting gold from seawater: kzfaq.info/get/bejne/oJuVotB135q-YHk.html

One could use Armonía. It would contain even more H2 than H2 itself compared by volume. Also a German university created a gel like substance what could store H2 cheap and sustainable. One would then fuel the care with water and separately that paste. Interestingly, they claim that if one extracts the H2 from that paste actually H2 (from the water) is created as "waste" in addition. So one gets more H2 out of that paste than one stored in it. Which is also a brilliant way to lower H2 production costs. -- sadly I haven't heart anything new about Armonía or that H2-paste lately.

Great video as always! Really engaging and with the right amount of detail to help understand the topic while still going straight to the point. Personally, exactly as I wouldn't give up on hydrogen even though (as for now) much of it is made from steam reforming, I also wouldn't give up on carbon as an energy carrier; I really hope that projects like Eni's Ecofining (hydrogenating oils up to actual green diesel) take off (as processes they go with a single reaction straight from biomass to fuel, so they are also quite energy efficient), but maybe some breakthroughs in mass oil production (like algal oil mass production) are still needed to render carbon-neutral carbon-based fuels an economically viable option!

I work for a transportation agency as part of a group researching our future fleet (alt fuel busses). Fuel cells have very appealing traits, but from the perspective of building out infrastructure, this technology has a lot of maturing to do. A transit agency using this to power a fleet would need either very convenient hydrogen stations nearby (3rd party operated), or the agency would have to build out infrastructure to make their own fuel. That raises questions about mission creep for a transit agency's role and quite a few sunk costs for safety provisions alone. Keep in mind as well, compressed natural gas busses must be re-certified by a qualified 3rd party before returning to service for any collisions over 4-5mph. I'd imagine similar safety requirements for vehicles carrying compressed hydrogen. That's just one more drop in the bucket where fuel cells' impressive initial features are 'watered' down in real world operating conditions.

Great video. It's easier for regulatory agencies to stay on top of power plants than individual vehicles. Also in power plants we can capture / filter/ scrub pollution's from the plants much easier than individual combustion engines. Electric, hydrogen electric, renewable fuels like biodiesel are all what's needed. We have areas in the US the naturally exhausts a ton of hydrocarbon gas, might as well use it to produce power then to just have it gas off into our atmosphere. All in all leaving the O&G to shift it's focus into power or newable fuel generation is the absolutely correct thing we should have been doing decades ago instead of trying to immediately replace them. Especially with the fear of losing our hydroelectric dams in the water states of US.

Hydrogen could probably bootstrap itself through grid-scale storage projects. The nature of storing hydrogen and the purity requirements for the fuel cell are something that wouldn't really matter a lot at a power plant (just another thing they have to monitor and control), but those requirements are a pain in a mobile application like in a car!

Please more hydrogen fuel cell content!!! As methane is a greenhouse gas itself, are the CO2 emissions of the conversion process to H2 less than just burning the methane? If so, it could actually be an amazing tool to allow governments to convert gradually (ie. build bulk hydrogen fuel cell infrastructure, and supply it with H2 produced via methane conversion, but gradually convert your H2 production to solar/electrolysis and bio-production over time).

Hydrogen could simply be made at any hydro electric dam like James bay or Hoover dam through electrolysis. The hydrogen could then be sent through an additional cables system with the existing infrastructure of the power lines than sold to hydrogen stations at gas stations or to individual houses for profit for the power plants and then taxed for the Government.

By pumping oxygen into oil wells we can oxidize the crude and separate hydrogen from carbon while its still in the ground. The hydrogen can be extracted through a filter and mineral ions can be added to the carbon dioxide to create a solid carbonate that just stays in the ground.

I am a hydrologist and I will say she is spot on with everything within her video outside of the concept , admittedly unspoken, that natural gas is dirty. Natural gas is actually extremely clean and is the cleanest of all fossil fuel types which is why it is used so heavily within the industry. Hydrogen cars compared to electric cars within all supply chains considered , electric cars are very “dirty “ especially through the mining process and still using gas to produce the electricity at every fill up. Hydrogen technology has greater potential to be cleaner throughout the entire process

Ok here is a thought .Electric car takes several hours to fully charge and burn it rather quickly and must be charged to continue to travel . Hydrogen car takes seconds to fuel from station and can be fueled while driving if set up to do so .1 takes a very heavy load off the grid while the other puts a heavy load on a grid that is heavly loaded, now what makes more since. Just a thought, what will you do when a governor tells you not to charge your car do to an overload on the grid.

The problem with Hydrolysis is that it requires scarce and expensive materials, like platinum, but in theory, we could use nuclear reactors to directly power Iodine-Sulfur Cycle, then mixing this Hydrogen (Called Red Hydrogen) with atmospheric Nitrogen to industrially produce Ammonia through the Haber-Bosch Cycle (Called Red Ammonia), which can be mixed with water and easily transported there where it's needed, like metallurgical, chemical and fertilizers industries, seaports, airports, land transport terminals, and so on... That's what we call a Red Ammonia Energy Matrix... I'm actually working in an investigation project to simplify this Matrix and someday scale it up to industrial level, hopefully.....

I am a huge fan of hydrogen energy, and I appreciate how you explained its operation in the first part of the video. However, I would like to point out that the second part of the video contains some inaccuracies and misconceptions. There are methods to convert plastic waste, car tires, and other organic waste (from the oil industry) into hydrogen energy using a closed-loop process called Pyrolysis. If done correctly, this process will not harm the environment since there are no byproducts that are released into the air. Your video is a “fly in the ointment” since it takes a great concept and makes it look bad. Pyrolysis can convert oil spills or any products from fossil fuels into green energy using “Green Way” technology. This technology exists, but some corporations may want to create confusion around this great concept. Finally, we need to concentrate our resources on storing H2 in dry cells instead of liquid, this will resolve the storage issue and make it more convenient. As well as releasing it to the public.

It'd be added weight and complexity, but I wonder if it'd be viable to just build a closed loop hydrolysis system INSIDE the car that runs off of electric car chargers. You'd lose the refueling speed benefit, but you'd gain the benefit of a vastly greater network to refuel from. The extra weight might reduce your range a bit, and you may need to top up the electrolyte and water occasionally, but I think as long as the complexity and weight isn't too much it'd be a viable way to do hydrogen fuel cell cars.

EV batteries are recyclable, and there is plenty of lithium in the world.

Hydrogen cars are electric cars, using a battery and motor for regen and even out the output of the fuel cell. Basically they are a terrible idea, with the only advantage being faster refuel time. Batteries being developed cut that advantage way down.
