Hydrogen is carbon-free if produced with renewable energy, and some experts see it as the key to decarbonizing certain difficult-to-abate industries. As of now, the fuel exists more in clean-energy models than in the real world, as almost all hydrogen is currently made with fossil gas.
But now we may be at the dawning of the green-hydrogen economy, as tens of billions of dollars in Inflation Reduction Act incentives encourage both startups and established companies to invest in driving down the cost of generating the carbon-free fuel.

The clean-hydrogen production tax credit in the IRA is incredibly rich, said Jane Sadler, an associate at think tank RMIs U.S. program, during a recent webinar. (Canary Media is an independent affiliate of RMI.)
Its definitely going to change the landscape of hydrogen, she added. Unlike some tax credits in the IRA, the uncapped hydrogen incentive is available as direct pay (rather than a credit) to any applicant for five years and 10 years to tax-exempt applicants.

(15,265 posts)Is there and improved efficiency at these karge scales ir are they just producing large amounts og hydrogen inefficiently?
Japan's hydrogen economy experiment has been a bust.
https://newatlas.com/energy/japan-hydrogen-policy-failure/
Using electricity to produce and compress hydrogen is very inefficent. The current infrastructure mentioned like steel pipelines and tanks can't be used fir pure hydrogen. It embattled stell.
For example itvtajes about 3x more electricity to produce and compress hydrogen for a hydrigen Fuel cell vehicle like the Toyota Murai the it foes to charge tghe battery of a comparable EV. For home heating a heat pump running on electricity is about 7x more efficient the using hydrogen to heat homes and businesses.
Hydrogen has it uses but if the industry ends up hogging green electricity and we get pushed into a hydrogen economy we may end up requiring substantially more green electricity and will pay more for things like transportation, heating, abd ekectricity.

(8,187 posts)...really only matters is there is an alternative option to compare it to.
The transfer of energy from any state to any other state is always inefficient, energy is lost when you charge your phone, when vehicles combust gasoline, etc, etc,.
However, we will not be able to use any energy directly from the source 100% of the time, we will need to store some of it for situations when we can not be wired directly to the source. A loss of energy, or innefficiency, for that needed storage will be the price to achieve that storage.
In a fossil-fuel system, Hydrogen will be needed for storing energy and for energy to be used in portable and mobile applications, yes, there are batteries as an alternative, but lithium is a finite resource, and also, battery power does not offer the combustion engine options that hydrogen does for uses when that is preferable.
Of course, choices will be made as to which form of stored energy is best for each different application.
The use of green energy to produce hydrogen will not overlap or "hog" the green energy produced for other uses when the hydrogen is made from dedicated solar/wind/hydro/nuclear sources. In other words, to produce green hydrogen, a plant is built that includes it's own green energy source, there would be no loss of energy from plants built to supply energy for other purposes.
And yes, in order to transition away from fossil fuels, we WILL need to produce all of our needed energy from green electricity sources for transportation, heating, and electricity, which are ALREADY becoming less expensive than fossil fuels.
As to the article about Japan's initial mistakes in developing a hydrogen economy, the article clearly points out 3 wrong approaches that Japan has made,
1) Japan is targeting hydrogen at the wrong applications
2) Japan has prioritized dirty hydrogen
3) The country's green hydrogen production sector is lagging behind
The article certainly does not imply that a Hydrogen industry in itself is a bad idea, it simply points out how Japan has not succeeded yet in their particular attempts.
In fact, the article points out that the third mistake that Japan has made, according to the article you referenced, is that they have not developed their Green Hydrogen industry fast enough.

(15,265 posts)I'm on a phone and going from memory. But a look at a comparison to gasoline. A gallon of gasoline contains 33.7kWh of energy. 1kg of hydrogen contains roughly the amount of energy. It takes about 38kWh of electricity to electrolyze 1kg of hydrogen and another 5 or 6 kWh to compress it.
So ~44kWh of electricity to produce 1kg of hydrogen containing ~33kWh of energy. Then when you convert that hydrogen back to energy there are losses as well. In the case of automobiles, about 25% to 30% of the energy used to produce hydrogen makes it to the wheels of an HFCV vs 80% to 90% for a battery EV.. A battery EV can go about 3x furthur then a comparable HFCV on the same amount of energy.
Think. Again.
(8,187 posts)...efficiencies of non-CO2 to CO2 emitting methods?
The only goal is to reduce and eliminate CO2 emissions. That's the only reason we are doing this.
If it takes a certain amount of inefficiency to replace a CO2 emitting source with a non- CO2 emitting source, so be it, we are achieving our goal.
Of course if there are multiple options of non-CO2 energy to choose from, that's where an effeciency comparison would matter.
What your post above is saying is that we shouldn't stop using CO2 emitting energy because non-CO2 energy isn't more efficient.
But efficiency isn't the goal we seek, non-CO2 energy is.
And as I mentioned, lithium EV batteries could only be a bridge between CO2 emitting power and something else due to the limited supply of lithium. Lithium batteries are a short term option. Hydrogen can be produced (using non-CO2 energy) in UNlimited supplies.
Right now, the only 'something else' is hydrogen. Why not go straight to hydrogen rather than have to build both a battery industry now AND then a hydrogen industry later?

(15,265 posts)efficient then using it to produce. For decarbonization of industrial processes or applications like shipping and long haul trucking it may nkje sense.
For things like personal transportation we will need 3x to 4x the amount of green electrucity to go the hydrogen route vs the battery EV route.
Fossil fuel are tje measuring stick thst the epa uses to calculate mpg-e (equivilent mile per gallon) fitr EV'S and HFCV's.. thst is why I quoted tge energy in I gallon gasoline.
From memory, I saw figures for the Toyota Mirai (HCFV) of 66 miles/kg of hydrogen. From what I've reads 1kg if hydrogen takes about 44kWh of electricity to produce and compress. A Tesla Model 3 uses about 0.243kWh/mile of electricity.
On 48kWh's of electricity the Tesla can travel 48kWh ÷ 0.243kWh/mile = 197.5 miles.

Think. Again.
(8,187 posts)We'll use energy directly from the non-CO2 source where we can and use stored energy where we can't use it directly from the source. Done.
And okay, we'll need 3-4X green energy for a permanent hydrogen vehicle industry than for a temporary battery vehicle industry.
So, let's get moving on it then...

OKIsItJustMe
(19,938 posts)One of the reasons why lithium is so nice to use in an automobile traction battery (or in a portable drill) is that (with an atomic number of 3) it is quite light, compared (for example) to iron (26) or lead (82.)
If your battery is just sitting on the ground, size and weight arent as important, and you can consider completely different types of batteries.
One of the interesting alternatives is a flow battery.

Do you really think someone like a realtor or a salesperson will buy a car that needs to stop for ~45 minutes every 2-300 miles? (That's if there is no line to get to the plug.)
And replace the battery every 8-10 years regardless of the mileage? Absurd.

(15,265 posts)"Efficiency
One of the most significant disadvantages of FCEVs is their inefficiency. Because of the complex processes involved both in producing and storing hydrogen and in converting the hydrogen into electricity in the fuel cells, FCEVs are generally only around 38% efficient, meaning that for every 100 watts of energy produced, only around 38 watts can be used to power the FCEV.
Unlike FCEVs, battery-powered electric vehicles are quite energy-efficient. While FCEVs are less than 40% energy-efficient, most battery-powered electric cars and other vehicles boast around 80% efficiency. This means that for every 100 watts of energy produced, nearly 80 watts will be used to power the vehicle.
When it comes to energy efficiency, battery-powered EVs are the clear winner, requiring half the amount of energy as FCEVs to generate power."
OKIsItJustMe
(19,938 posts)When you charge an EV in the US (on average) about 60% of the electricity came from burning fossil fuels. If you do all of the calculations, if you start out with a certain quantity of fossil fuel, it is somewhat more efficient to reform it, generating hydrogen to drive a FCEV than it is to burn it in a fossil fuel generating plant to produce electricity to drive a BEV.
If the grid were totally green, the BEV may be preferable from an efficiency standpoint. On the other hand, batteries (even lithium-ion batteries) are heavy. As the weight (or range) of a vehicle increases, you need a larger and heavier battery. As this trend continues, you wind up with a vehicle that puts a lot of energy into carrying around its battery
For this reason, at this point, while Ford has a battery-powered F-150, for their "Super Duty" line of trucks they think they will be using hydrogen fuel cells.
EXECUTIVES STATE FORD SUPER DUTY WILL LIKELY GO HYDROGEN BEFORE GOING FULLY ELECTRIC
Batteries make the most sense for small vehicles with relatively short range. Hydrogen may make more sense for larger long-haul vehicles (especially things like boats, trains, planes.) The question is, where is the cut-over?
Think. Again.

Today's grid stats will be meaningless as we (hopefully) keep displacing more and more CO2 emitting sources with non-CO2 sources.

(19,938 posts)Ive been dealing with this for too long. People want to pretend we have a clean grid, because (hopefully) some day, we will.
In the meantime, we need to deal with todays reality.
In the final analysis neither batteries nor fuel cells are magical. They both have advantages and disadvantages, and frankly, it's not a question of which is better for the environment? but which is less bad?
The whole one person, one car model is horribly inefficient, whether that car is powered by green hydrogen or green electrons.
Think. Again.
(8,187 posts)You write:
The whole one person, one car model is horribly inefficient, whether that car is powered by green hydrogen or green electrons.
This is the actual truth.
As we now know, there is no magical energy source when we are trying to use more than natural processes produce and need.
Yes, CONSUMPTION is the core issue.
Not only do we have to displace fossil fuel energy sources with less-damaging alternative sources, but we also must find the balance of what we use and what we are willing to pay the price to produce.
But I disagree with you on this, you write:
We know we are at an unlivable place, that's really all we need to know in order to understand that we must get away from this place as quickly as humanly possible.
That's what our focus must be on.
We can look back later, once we've left, if we are interested in understanding what this place actually is (was?).

There are areas where green hydrigen make sense.but until the efficiency of electrolyzing water and compressing hydrigen and transporting it improve it is a waste of energy for many applications. The law of thermodynamics are hard to overcome.
If I wanted to go off grid and add enough solar and or wind power to either charge an EV or power an electrolyzer and compressor to fuel a hydrogen fuel cell vehicle I know which choice I'd make. The hydrogen fuel cell vehicle would take st least 3x the number of solar panels to produce hydrogen vs charging the EV. There are economies of scale in both cases if you are doing it on a large scale but unless electrolyzer efficiency is greatly improved green hydrigen is a waste of energy.
OKIsItJustMe
(19,938 posts)You really need to look at the application in detail, examine the advantages and disadvantages of possible solutions, perhaps the most efficient solution is not the most convenient. For example, you can store energy in batteries, or by splitting water, and putting it back together again. Or, you can store it as potential energy in a gravity battery.

(8,187 posts)Hydrogen, just like batteries, has appropriate and innappropriate uses depending on the needs they can fulfill.
Some situations such as power or heating needed 'in the field' where "refueling" by electric cables isn't possible will be well-served by transported-hydrogen powered equipment and vehicles, and the efficiencies required will also be dictated by the use and goals of the machinary needing to be powered.
Green hydrogen production does not have to be limited to electricity that is generated and intended for grid-use. In fact, most of the hydrogen production plants are planned to have their own dedicated solar, wind, nuclear, or hydro electricity sources specifically to avoid diminishing the supply of electricity needed elsewhere, which also negates the concerns about electrolyzer efficiency, we will simply generate the electrity we need (from non-CO2 emitting sources) to produce the amount of hydrogen we need at whatever efficiency it does, since there is no other purpose for the electricity produced, the efficiency of the hydrogen production will just be whatever it is.
Hydrogen also offers the capability of being used in situations where a non-CO2 form of combustion is best for a specific purpose.
And we really shouldn't make the same mistake of building a new energy economy entirely around a limited resource such as lithium, although there is hope that new battery storage tech will be less limited and ecologically damaging to acquire.
And I DEFINITELY agree with you about the fossil fuel industry's substantial attempts to stall and slow-walk the transition!
By creating confusion about the potential production and uses of any and/or all of the various non-CO2 options we already have, they are succeeding in slowing down the general public's acceptance of any (or all) of the variety of ways we can and should be displacing fossil fuels.
