Green Hydrogen Could Power Your Life Sooner Than You Realize - These Companies Are Making It Happen

[@maxloewe9162]

Green hydrogen is not "an unlimited source of energy", it's a way of storing energy produced by renewable sources and is as limited as these sources.

[@skierpage]

And those renewable sources go a lot further if you electrify transportation, heating, energy, and industrial processes directly instead of making an inefficient detour through hydrogen.

[@OtisFlint]

@@skierpage Exactly, which is why hydrogen is going nowhere, outside of niche applications.

[@chrissmith2114]

According to the EVangelists and greenies renewables are a very cheap and limitless resource, ( but very unreliable as it turns out when you do not have limitless and very expensive storage) Hydrogen is really the only way to make use of unreliable renewables because at least you can store the hydrogen.

[@skierpage]

@@chrissmith2114 it's not "according to," it's truth. Go argue with the economists at Lazard who publish Levelized Cost of Energy analysis now up to v.15. Ignore the reality that the majority of new generation everywhere in the world is wind and solar because they're cheap and quick. Intermittent does not mean unreliable. The obvious thing to do when wind and solar are generating is cheaply charge your EV and heat or cool your building and water in advance. Maybe make green hydrogen as well, but in all the hours that renewables aren't producing, electricity is more expensive, and idle electrolyzers increase your capex. And there are other ways to store electricity; hydrogen storage has yet to prove itself. Even if you don't store electricity, renewables are still a huge win for the environment, because you're shoveling millions of tons LESS dirty fossil fuel into coal and gas plants for hours, days, weeks at a time. (Yes, China is building more coal plants along with hundreds of gigawatts of wind and solar but many of its coal plants have capacity factors less than 25%.)

@@chrissmith2114- Renewables are indeed cheap, and with more and more Grid Scale Storage batteries being installed, it can supply all our needs. Hydrogen makes no sense because the end to end efficiency is terrible. The Hydrogen Cult survives on the irrelevant facts that they keep trotting out. It's the most abundant Element... it's Green Hydrogen, there are no tailpipe emissions... yawn. None of this matters. End to End efficiency is what matters, and it's three times better if you have BEVs. Hydrogen had its chance over the past 50 years, and it didn't make it because it's hopelessly impractical and inefficient. Now BEVs are a reality, it has zero chance. If it couldn't compete with ICE cars when there was no competition, it's a dead duck.

The problem with H₂ is that you waste ⅔ of the input energy as heat; the hydrogen energy chain is about as efficient as diesel. You'd be far better off using the energy as electricity. Solar and Hydro cost money; the common spiel that "It's from renewables so efficiency doesn't matter" is not a realistic argument.

[@jimj2683]

It is not as simplistic as that. You have been brainwashed by Elon Musk. You have to look at cost, not just efficiency. Is it cheaper to export renewable energy by DC cable (plus batteries) or as a hydrogen product? Because one windmill in the UK produces much less energy than one in South Chile for the same cost. Then it becomes more a question of what is the cheapest way to store and distribute this cheap energy.

Add to this the comparison between distribution of electricity vs any fuel. Grid distribution of electricity loses less than 5%, and is fairly low maintenance thin infrastructure. Plus some of the electricity can be created at the endpoint like rooftop solar which cuts distribution losses and bypasses oligopoly providers. Any fuel needs to be distributed with storage and transportation infrastructure which is high maintenance and a lot more materials. Something like 30% of fuel is used just transporting fuel. Hydrogen is even harder to store than gasoline/diesel. Grid electricity and electrified transportation have a massive head start over any fuel solution just with the efficiency of the distribution.

Hydrogen will never replace BEVs unless there are gigantic changes. It's ridiculously expensive and inefficient and the economics just don't work. In Europe Shell is closing their very few hydrogen filling stations. They have already realized that it just doesn't work.

[@IMGreg..]

Currently the best application for hydrogen is where BEV fails due to size or weight capacity. Large mining and farm equipment, transoceanic shipping, trains and heavy long haul trucking. Trucking still has weight per axle restrictions that reduces the load they can carry because the batteries weigh so much. The above industries produce the lions share of carbon in the transportation category plus aircrafts. Within that segment cars are a small carbon producer. Batteries can't run a tank and get the weight under 60 tons or fuel a fighter, a frigate or a harvester combine running 16 hours per day, in a wheat field miles away from a charging center. Hydrogen can be transported just like diesel can and diesel engines can be converted to run on hydrogen, which is going to be important for small island nations using diesel generators to produce electricity. They have daily blackouts as it is imagine adding BEVs to their power consumption. We have a multi fuel economy now we'll need multiple sources of green energy to power the globe in the future.

Hydrogen is the most versatile element in nature.

[@vlhc4642]

Hydrogen users are irrelevant to the problem, hydrogen users can burn both green and grey hydrogen, grey hydrogen is just burning natural gas with extra steps so will never be economical compared to just burning natural gas, which means at end of the day the only question is how much renewable capacity you have to generate potentially economical green hydrogen. As of right now China dominate renewable energy generation, China is the only country with large enough renewable capacity to potentially produce green hydrogen economically, and China is the only one actually building green hydrogen distribution, which means the green hydrogen economy is just where you buy Chinese renewable energy stored in hydrogen form. And let's face it, most hydrogen will be gray, because the whole point is for oil companies to sell natural gas while pretending they're "green", if people actually cared about the "green" part they'd be investing in renewable, as it is "green" is just a PR stunt.

[@stevesonnaquesta]

Green hydrogen is just generating renewable electricity, with extra inefficient steps.

On top of that there is a lot of chemistry, that would benefit from using hydrogen. first and foremost stealproduction.

[@skierpage]

@@MusikCassette so you agree, the issue is how big are the niches. Obviously hydrogen is a relatively small tail on the big dog of terawatts of renewable energy and storage, despite the cynical hopes of fuel companies addicted to selling atoms instead of electrons. Hydrogen used in refining crude oil into liquid fuels needs to die along with burning fossil fuel; I'm not sure how much hydrogen the rest of the chemical and plastic industries use. Look at Michael Liebreich's hydrogen ladder for the unavoidable uses of hydrogen vs. the dumb uneconomic ones, and Michael Barnard has good analysis of individual use cases for hydrogen.

[@spencernorman2626]

What everyone dunking on hydrogen seems to conveniently forget is that 747s and cargo ships will never be capable of running on batteries. Semi-trucks going cross-country don't have time to sit around half the time while charging batteries, all while carrying 15,000 pounds of batteries that would have been cargo weight otherwise. Batteries are great, I agree, but they aren't omnipotent and will never be capable of all the things we want to do with heavy vehicles. Bulldozers, planes, dump trucks, and basically everything that weighs over 10,000 pounds or is supposed to carry 10,000 pounds of cargo more than 100 miles need hydrogen. Everything lightweight, low-range, and for infrequent use can use batteries, and that definitely makes more sense.

The transportation industry only likes hydrogen because it needs to be transported. They hate electrification because it is transported by grid not by truck. Nearly 30% of the global freight transportation industry is just trasnporting fuel. If we reduce our use of fuels it is a lot better for the environment not just direct emissions but also the reduction in cargo transportation demand. So electrified transportation is great for the environment but bad for revenues of global cargo transportation companies. So the cargo industry will gladly support the greenwashing of a fuel over electrification, because they like profits more than they like their grandchildren.

It's interesting that the interviewer doesn't know enough about hydrogen to ask questions or clarify numbers. Not interactive at all, just letting the companies speak. Hmm. 2:09 love how Plug Power avoids the inefficiency by saying putting in 1MW gives you 420kg of H2. Yes, putting in 1MW all day long or 24MWh gives you 420kg per day. That's 57kWh/kg. A very standard 58% efficient electrolizer. Not counting compression, liquification, transportation, etc. Then he claims a 2:30 it could supply 400 standard sedans. Yes, but only for one day of average driving. Not fill them up like at a gas station, just fill them with one day's worth of hydrogen. I find Plug Power tends to be pretty dishonest in general. 12:18 uses 5MW and produces 2 tons. Since hydrogen is usually measured in kg, I'm assuming metric tons or 2000kg. So 5MW x 24 hrs = 120MWh to produce 2000kg, or 60kWh/kg. That's also average for producing H2 at atmospheric pressure. For reference the most efficient FCEV, the Toyota Mirai can get 70 miles on 1kg of H2, a Tesla Model 3 can get 240 miles on the same 60kWh of electric. 13:21 And then let me get this straight. Your selling Florida Power and Light electrolyzers to produce H2 from electricity to blend with NG and run through a turbine to make, what? ..... electricity. I get it, probably for peak demand. So use 120MWh to produce 2000kg (66MWh hydrogen), then run it through a turbine that's maybe 65% efficient to get 43MWh back out. Hopefully, it's rare that you have to actually use that method.

And, no hydrogen is very difficult to store - in fact it's one of the most difficult fuels to store in that it leaks through everything including solid metal; and it's reactive too, embrittling metals.

The only companies that will consider it will be for promotional "Look at how green we are" deals with little actual use. Currently, the cheapest source of hydrogen is steam reforming of natural gas, current retail price about $16 per Kg. Hydrogen from electroysis costs even more. So, how do they plan to get to $2 per Kg? By somehow magically getting "renewable electricity" at only 2 cents per Kwh - but that means EVs could get electricity at that price, and hydrogen still couldn't compete. The mythical "$1 per Kg" price isn't a price they can actually achieve, it's the price they would have to achieve to be economically competitive to electricity - and that sim;y isn't possible.

I believe it will be tough to get to total "well to wheels" cost for hydrogen to be competitive, even if the generation cost is near zero. Storing and transporting hydrogen is very costly and difficult due to it's small molecule size, high pressures and low energy density. I think for some niche applications, the cost will be less of a problem and the higher energy density than batteries will win out. But batteries charged on the grid and in vehicles will be more efficient than hydrogen, which means it will likely be more expensive with hydrogen. Durability of fuel cells is still not there after decades of work and they are still very expensive. Again, some applications it may work (hydrogen in power plants), but I think batteries as way of storing energy will be cheaper in the vast majority of cases, especially as their chemistries get better.

Hydrogen for vehicles is the Fools Gold!

[@Charvak-Atheist]

Hydrogen powerd Cargo Ships, Airplane is fine. But Hydrogen power train doesn't make any sense. Train can just draw power directly from overhead electric cabel. There is no need of staring energy in this case. You are using electricity and water to generate Hydrogen. And then using that Hydrogen to again get electricity 😅 Why not use electricity directly. Yeah for Ships, Airplanes it makes sense because there is no overhead cabel. You have to store energy.

[@jjamespacbell]

BEV Forklifts make so much more sense, at the end of a shift or during break times plug into a charger, when you have tens or hundreds of forklifts at a facility it is simple to add many chargers in appropriate places. When you see the Hydrogen vehicles refueling lines in California, people in queues 5 or 10 deep it takes 30 or 60 minutes to refill and you have to stay with the vehicle. With EV chargers it does take 15 or 20 minutes but you plug in and walk away so when you return vehicle is ready to go. If you are a forklift driver how do you want to spend your lunch break?

[@jamesmorton7881]

I missed the part about how much that electricity cost to make enough H2 to fill the tank ( of a car. ). Hint it is not less than $4.50 per gallon of gasoline

[@5353Jumper]

And also that electricity has emission. Of course they will say, "leta use solar to make the zero emissions electricity for the hydrogen production". But that all needs to be compared to just plugging that solar into the grid and bEV and just skipping the inefficient fuel concept all together.

[@maxwell.l.greene]

@user-ky7iz6up1v You're WAY off on the cost of electricity. Listen to 16:25. Solar will cost $0.02/kWh and H2 will be $1/kg in a few years. $0.12/kWh is expensive even for household electricity.

[@5353Jumper]

There is a lot more cost to green hydrogen electrolysis than just the electricity. There are consumables more than electricity and water, there is also the cathode/anode replacement costs. Current estimates at $3-6 per KG cost (not consumer price, just cost to produce) Which makes it sound kinda equal to gasoline but there are a lot of other factors along the way that will make it more expensive by the time it gets to your vehicle. Including transportation, losses, more expensive storage, taxes and someone somewhere is going to want to make some profits. All combined at the filling station most guess around $15 per KG which is a lot higher cost per mile than gasoline (and way more than just taking the same electricity and putting it into a bEV).

[@stevesonnaquesta]

@user-ky7iz6up1v Forget the hydrogen (for your purpose). The 50 kWh electric energy required for producing that 1 kg H₂ will get you about 150 miles in an electric car.

[@fbkintanar]

I am impressed by recent changes in the long-haul shipping industry, specifically the emergence of container ships using green methanol. One of the early application domains for green hydrogen is as feedstock for the green methanol used in container ships. Maersk, the second largest container shipping company in the world, says they are on track to move 25% of their ocean operations to green methanol by 2030. Although biomethanol (where organic waste is the feedstock) might be part of that, they expect most to come from electrolysis and green hydrogen (so-called e-methanol). Maersk's first green methanol ship is already operating as a feeder vessel in the Baltic, and they expect to take delivery of 25 much larger container ships with methanol engines over the next two years or so. Other container shipping companies are ordering methanol-capable ships as well, I have heard there are between 100 and 170 additional ship orders. As recently as 2019, long-haul shipping was considered a hard-to-abate sector. Today, it looks like large shipping companies like Maersk can meet a net-zero target by 2040. Their ships, and other parts of the logistics chain they are responsible for, will create a massive and secure market for emerging green hydrogen suppliers. Even with existing prices, they expect that the transition to e-methanol (and future fuels like ammonia and direct combustion of hydrogen) will be economic, in part because their customers are also committed to net zero, and are willing to pay a small green premium to send their cargoes on green vessels and green logistics chains. As green hydrogen production scales up, its price should go down and the need to pay a green premium should disappear. Just like it is now cheaper to build new electricity capacity with renewables rather than coal (you can't get financing for a new coal plant any more), it will be cheaper to fuel your ships with green fuels rather than polluting hydrocarbons. Of course, even if that price point for green hydrogen is reached sooner rather than later, there will still need to be massive capital investments and time in order to convert existing fleets and industrial capacity to hydrogen. But at least the end goal is in sight. Shipping represents 3% of global emissions, and if companies like Maersk attain their broader objective of decarbonizing the entire logistics chain (terminal operations, trucking, warehouses, etc.), that will address 11% of global emissions. The discussion 18:50 about trains with diesel engines in the US where electrification is just 1% (compared to 60% in Europe), indicates that it could be another sector ripe for a rapid transition to a decarbonized future.

[@twisted_void]

Absolutely. Future of shipping looks encouraging. Would like to add though that while shipping is still overwhelmingly using fossil fuels, what I think press fails to sheds the light on is that shipping has already been doing a lot of improvements with existing technologies to reduce carbon emission. Despite merchant fleet growing by 40% since 2008, overall carbon emission actually dropped since its high in 2008.

[@mb-3faze]

Green methanol is profoundly different than this green hydrogen fossil fuel scam. With green methanol (provided it really is using atmospheric carbon and green electrons) is just a way of storing electrical energy for use when away from a convenient power source. Nothing particularly wrong with that and far better then burning bunker fuel. However the big push (by big oil) is domestic hydrogen, particularly for transportation. It has no merit thermodynamically or economically but that is not stopping the fossil fuel people from promoting it like in this propaganda video; trying to pull the wool over the ill-informed with green washing. They know all too well that the bulk of the feed stock for the hydrogen will be methane which they will be only too happy to supply - at vast environmental and commercial cost.

[@rogerphelps9939]

Why do that and greatly reduce the calorific value? There is not enough biomass around to meet the anticipated demand for methanol anyway.

[@tedwalford7615]

This whole story seems to have pointedly ignored the honest economics of the production, storage, and transportation of hydrogen. Not even counting the infrastructure, this hydrogen fairy tale is presuming mystical other sources of practically free energy PLUS government subsidies, both of which these company managers did mention.

[@mazdamaniac4643]

This is all well and great, but the on-vehicle storage problem still isn't being discussed. The hydrogen needs to be stored in a tank at either a very high pressure, or a very low temperature, but so far no manufacturer has managed to make a storage tank that's light enough but must also survive repeated low-high temperature/pressure cycles without catastrophic failure. They still haven't figured out the embrittlement problem, because hydrogen causes most metals to go brittle and crack. Until these big problems are solved, hydrogen is simply not going to work in any safe, practical manner to be certified on a road vehicle.

[@Amukalalu]

Toyota has been using carbon fiber in there hydrogen vehicles to store hydrogen which is working out just fine.

[@mazdamaniac4643]

@@Amukalalu Uhm, that's not what I heard mate. Carbon fibre isn't some wonder material, it delaminates when subjected to repeated pressure cycles...as the unfortunate folks aboard the Titan submersible found out. I've seen a report by the NHTSA on hydrogen storage tanks that were designed for road use and had to be tested by them to be certified for use in vehicles, one stainless, several types of carbon fibre (some with a ptfe liner because CF is porous to hydrogen) and others that were steel in various designs. Every single one of them failed every test. The stainless steel one started to become porous until it cracked, all of the carbon fibre ones delaminated (either due to cold temperature or pressure cycling) with the ones with the ptfe liner only lasting a little longer, because the liner tended to collapse inside the tank, all of the steel ones fractured from embrittlement. Not one of the tanks under test lasted more than 100x temp/pressure cycles before catastrophic failure, some of the cryogenic tanks ruptured on the test stand while they were sat there, doing nothing. Imagine what would have happened if that was inside a vehicle in a car park...kaboom. It's a very serious problem, so bad it seems, that the media just doesn't want to cover it for political reasons because they're being paid to portray hydrogen technologies as all shiny and the fuel of the future, disregarding it's inherent problems. Here in the UK, the Government was making a big deal about piping hydrogen through the existing natural gas network to people's homes. It sounded great, until it was revealed that most of the pipework is made out of HDPE...a material that is completely porous to hydrogen, with the rest being steel..which embrittles and fractures. Trying to do this as-is would have resulted in major gas leaks under roads, streets and housing until it found an ignition source. The cost of replacing the network with PTFE-lined stainless steel pipes ran into the £billions and would have led to an infrastructure project that would take decades to complete. You don't hear about hydrogen gas in the natural gas network anymore...that idea fizzled out as fast as the gas would have done through the pipework. It was also found that you'd need 3x as much hydrogen to burn the same amount of heat as natural gas does. The energy requirement to generate that much hydrogen to replace natural gas is immense, never mind storing it in specialised tanks. In the end, it was deemed that it just wasn't worth it and practically every hydrogen-generation project in the UK has been quietly shelved since.

[@frequentlycynical642]

Uhhhh.....and where does that electricity come from to make the hydrogen? If it's not renewable, or perhaps fusion in the future, hydrogen will require lots of solar, wind, hydro, and fission to be green. If you are making all that electricity, wouldn't it be more efficient to use it directly? Even with battery charge/discharge losses, surely a lot less than making hydrogen. And then, of course, hydrogen must be compressed and stored in cryogenic containers, which lose a percentage every day just sitting around.

Do you know ?!? H2 cars are 100% electric, H2 goes into a fuelcell and electricity comes out, which replaces the battery. The fuelcell in a Mirai cost $35,000 and its only good for 150,000 miles. Electrolysis puts 3X more electricity in than you get back. The above plus additional inefficiencies along the energy path, H2 cars require 5X more electricity at the generation source than BEV's The above means a world of H2 cars needs 5X the energy production (thus 5X the cost) as a world of BEV's H2 station cost $10,000,000 - NACS (Tesla) chargers cost $50,000 There's so much more cost throughout the H2 process, the complexities of compressing, storing, transporting, all the infrastructure requirements, in addition to the high cost and degree of personnel and maintenance required throughout the entire complex H2 ecosystem. If this hasn't convinced you that H2 is a fools errand, then you're drunk on the koolaid.

[@jensstubbestergaard6794]

The argumentation against Hydrogen is centered around alledged inefficiencies leading to too high economic costs. The cost of solar and wind power is going to continue down and so will the cost of generating, transporting and storing Hydrogen. Transporting and storing electrons is very expensive and allthough it too will go down in cost there simply is less potential for cost drop and hardly any potential for efficiency improvement.

[@ecoideazventures6417]

Summary at @16:40 - It takes 50KWh of solar power to make one kilo of hydrogen, which is equivalent of a gallon of gasoline. So you get green solar hydrogen for 2 cents per 1KWh, and you use 50KWh to make a one kilo of hydrogen, so you can see how quickly we get under 2 dollars per kilo. But sadly that is a little far away from the DOE goal of one dollar per one kilo of hydrogen!

[@maxwell.l.greene]

Let me finish that math for you: $0.02/kWh * 50 kWh/kg = $1/kg

[@chrismuir8403]

That is also ignoring the capital costs of building the electrolyser, and hydrogen storage, and all the other infrastructure involved. That has to be added to the sales price. Current retail price of hydrogen fuel is $16 per Kg from the cheapest "grey hydrogen" source. Hydrogen from electrolysis is not cheaper, not without heavily subsidized electricity. and if they can get electricity for 2 cents a Kwh, so can other companies and hydrogen still can't compete with much cheaper electricity.

[@Clark-Mills]

While all Hydrogen Fuel Cell (HFC) vehicles have a (small) battery and electric drive chain, the problem with HFC's is the inability to store energy via regenerative braking. With an EV you can recoup most of your energy, and in trucks it makes air / exhaust brakes redundant (and effectively silent). The tiny buffer-battery that HFC drive chains use are overwhelmed pretty much instantly (similar to the Prius' regen).

[@Foersom_]

That would depend on the size of the battery. A FCEV truck normally have a battery size similar to a PHEV truck, so capacity and power sink for regen braking is ample. E.g. Diamler GenH2 trucks has 70 kWh battery. A battery that size allow them to use smaller fuel cell and run that more efficient with stable power generation.

[@Clark-Mills]

@@Foersom_ Agreed, but when we had our Prius the battery was generally kept at ~70% charge for when you could run on pure electric. The 30% was available for regen, and 30% of "tiny" is minuscule :) and didn't help much at all when traversing ranges. Ok for city start/stop but low value for out-of-town. HFC buffer batteries will always be small as the fuel-cell / mini-EV / ICE systems in the HFC vehicles already take up so much weight/volume.

[@Foersom_]

@@Clark-Mills What does a Prius HEV passenger car have to do with FCEV truck? Nothing. Your experience with the limitations of Prius HEV battery, has no relation to FCEV trucks, where the battery is 50x larger. FCEV is possible solution for long haul trucking. Alternative we can use more trains that moves truck trailers for the long haul, and EV trucks that perform shorter hauls. FCEV is also a solution for trains where no overhead catenary exist. FCEV may also be a solution for ships.

[@Clark-Mills]

@@Foersom_ The Prius is mentioned as, similar to HFC, you have energy stored in the small battery for actual motive power. In a FFC vehicle you do not drive the motor directly from the fuel-cell, rather you "charge up" the battery from the fuel-cell and then use that energy to drive the wheels. In a HEV it's similar, the ICE charges the battery to a point leaving some headroom for regen. The limitation of regen is a real setback for HFC.

[@Foersom_]

@@Clark-Mills The limitation of your HEV Prius has nothing to do with a FCEV truck that has a battery 50x the capacity of a Prius. So please stop that nonsense comparison. "rather you "charge up" the battery from the fuel-cell and then use that energy to drive the wheels." Actually, the fuel-cell power will go directly to the motor, only excess power from fuel-cell will charge the battery. This allow fuel-cell to run with stable power output which allow to use smaller fuel-cell and run it more efficient. "The limitation of regen is a real setback for HFC." Nonsense. With a 70 kWh battery as used by Diamler there is no practical regen limitation.
