How offshore wind-to-hydrogen could help fill Europe’s clean energy demand.

So-called green hydrogen, produced through electrolysis of water using renewable energy, currently accounts for only about 1% of global production. It is also about three times as expensive as its grey counterpart, produced from fossil fuel sources.

Are floating turbines and electrolysers a solution to scaling green hydrogen?

Ok, Let’s talk about #hydrogen Fuel Cell Electric Vehicles (#FCEV) as an alternative to Battery Electric Vehicles (#BEV).

A FCEV uses the same electric motors as BEVs but gets its power from chemically reacting H₂ with O₂ from the air in a way that produces an electric current - a fuel cell. None of this is new technology Fuel Cells were a mature and reliable power source by the time the Apollo program was landing people on the moon. The issue with fuel cells is the same as with Enteral Combustion Engines(ICE) they are most efficient in a very narrow energy band great if the goal is to power the life support on a space craft, but not for the extremely variable loads needed to drive a car.

For this reason, FCEVs are hybrids with the same Li batteries as BEVs and ICE Hybrids like the Prius. Like ICE Hybrids they use the battery to accelerate and as storage for regenerative breaking with the fuel cell providing a constant recharge.

Why I’m skeptical of FCEVs

1) Greenwashing Hydrogen. FCEV advocates will point out that the only tailpipe emission is water vapor. The question is where does the hydrogen come from. By far the least expensive way to produce hydrogen gas is to crack the hydrogen atoms off of petrochemical hydrocarbons. As a mater of basic chemistry it takes far less energy to crack hydrocarbons than it does to electrolize water. And unlike the electrical grid where technologies like solar, wind and nuclear are already deployed and becoming an increasing share of our electric grid. Processes to produce hydrogen from water at anything close the the cost to strip it off fossil fuels is in the same development stage as cold fusion. at least for the next decade green hydrogen will be a premium product only available to the wealthiest buyers.

2) Hydrogen storage is hard. To fit enough hydrogen on a moving passenger car for it to have a 300 mile range requires pressures of 10,000psi (700 bar). The kinds of pressure vessels that can safely handle that pressure are expensive, and need regular inspection. Having had to keep a compressed air tank of just 200 psi in a fixed certified, I can tell you that there will be significant costs to regularly inspecting a 10,000 psi tank full of flammable gas that needs to survive a collision with one of the 2023 lineup of full sized puck up trucks.

But that is just the start. Hydrogen leaks. No matter how good you think your valves and fittings are the smallest molecule in the universe stored under huge pressure will find a way out. Ask anyone who has experience in the space industry where hydrogen is already the fuel of choice and they will tell you that hydrogen leaks are just a fact that has to be engineered around. On a vehicle this will be a small annoyance but at a fueling station this will be significant. The farther Hydrogen is transported and the longer it must be stored the higher the losses. There is also the energy factor of compressing that gas. To the best of my knowledge the prodigious amount of work done to pressurize the fuel is never recovered

FCEVs and BEVs both started to be produced about a decade ago, and while Tesla has scaled out its supercharger network world wide in that time. Hydrogen has less than 100 filling stations all in California. While these stations can fill a car in 5 minutes, they can only fill 2 to 5 vehicles before spending an hour refilling their high pressure storage tanks. One could argue that all Hydrogen needs is an eccentric billionaire ready to lose money for a decade building out infrastructure, however I think the infrastructure challenges with hydrogen exceed even Musk levels of ambition.

3) Cost. My M3 already costs noticeably less per mile that the equivalent ICE vehicle. Baring a huge technological leap, hydrogen will always be more expensive. because the least expensive hydrogen is processed out of the same fuel that runs ICE cars and provides less energy per molecule than those hydrocarbons when reacted with O₂ hydrogen cannot help but be a more expensive fuel.

So why are hydrogen FCEV still a thing? Well the vehicles are lighter, fueling times are comparable to gasoline, and the petrochemical industry is desperate for them to succeed. The oil industry can see the writing on the wall as states like California will ban new ICE vehicle sales in 2030. While holding out hope for a green hydrogen future a generation away, they can continue to have a market for their product as gasoline and diesel phase out. “Hydrogen will become the green fuel of the future” explain their sock puppets knowing that dirty hydrogen from their product will always have a price advantage. And to be fair, turning a mobile source into a point source of emissions does provide the opportunity for carbon capture (so called Blue Hydrogen), but all this still add even more cost while BEVs already have a price advantage in their fuel - not to mention that every home in the developed world has the infrastructure to charge BEVs.

Why write all this? Because when you get down to it most of the #FUD being spread around #EV s is coming from FCEV advocates who are trying not to let hydrogen become the betamax of the transition away from ICE transportation. In doing so they are making it harder than necessary for the world to move away from ICE transportation.

Beware people talking clean hydrogen, they are the ones who brought you clean coal
https://reneweconomy.com.au/beware-people-talking-clean-hydrogen-they-are-the-one-who-brought-you-clean-coal/

"Clean Coal" is a furphy, and it's looking like "Clean Hydrogen" is unattainable. In reality, practically all hydrogen made today is extracted from fossil fuels, or is made from water by electrolysis that's powered by a non-renewable source of electricity.

Some people talk about "Blue hydrogen" and claim they're cracked the secret of making it in commercial volumes at a price that's competitive with renewables, but they're not being honest with you about the cost or the quality of their product. Proponents claim that coal — such as Victoria's incredibly dirty, low-quality, high-pollutant brown coal — can be transformed into "Brown Hydrogen" or "Black Hydrogen" by capturing the carbon liberated during the hydrogen extraction process using Carbon Capture and Storage (CCS). Same goes for "Blue Hydrogen" that's extracted from fossil gas.
They're sorta correct, in the sense that you can get out hydrogen. But if you blink you'll miss seeing where the Carbon goes. By then, they'll attempt to scratch off the label to rebrand their dirty hydrogen as "Green Hydrogen".

Herein lies the scam: they're saying is can be done cleanly. The problem is that they're using CSS as part of the process. It would be nice if CCS worked at an industrial scale at any price, but it doesn't. Countless millions of dollars have been poured by governments around the world into CCS pilot-plants at fossil fuel companies. The fossil fuel companies have all pocketed the money and failed to produce results.

Scratch the surface of any hydrogen-bro, and you'll find a hydrocarbon-bro who's deliberately propping-up the unsustainable coal/gas/petrol industry or is an unwitting fool who's science-illiterate.

Hydrogen opponents often point to carbon footprint of SMR H2 as a problem. In fact 50% of SMR H2 comes from splitting the steam molecule. 50% of CO2 comes from burning natural gas for process heat. What if a carbon neutral non food feedstock such as algae biomass was used instead of nat gas?

There's gossip about Treasury punting the #GreenHydrogen #45V tax credit rules decision until the fall. Anything concrete to read?

One of the neglected products from production of green hydrogen from electrolysis is pure O2. It apparently has lots of uses and a sizeable market.

Some interesting numbers. 100kWh renewable => 35kgCO2 nat gas = 290km small gasoline car = 470km Toyota FCEV on SMR H2 = 270 km Toyota FCEV green H2 (gas->gas exchange) = 770km Tesla 3 (non winter gas->gas exchange) = 300 km Tesla 3 (non winter gas->coal exchange)=400kWh heat pump heat. Notice the FCEV quirk. Comes about because SMR is a lower carbon way to make H2 than slapping electrolyser on existing grid.

In a climate crisis it is important to start now to decarbonize not to wait for new tech to mature. Green steel even makes sense with SMR hydrogen according to this study.

Imagine Ontario were to built a non fossil grid with steady output at 2022’s peak of 23000MW. That would require 201TWh/yr. 78TWh/yr extra non fossil power would be needed. 15 TWh/yr to cover gas, leaving 63 TWh/yr available to valley fill with electrolysers. That would produce enough H2 to fuel 168 billion km in Toyota Mirai FCEV. Pretty close to the 200 billion km/yr driven today.

Continuing my previous toot; Ontario produced 14300 kWhr of wind power in 2022. That was used to offset gas generation on grid (0.35kgCO2/kWhr) for a savings of 5billion kg CO2/yr. If instead Ontario had dedicated all that energy to green hydrogen destined for personal vehicle transport ( 19kg CO2/100km) they could have saved 7.2billion kg CO2 with Toyota Miria FCEV driven 38 billion km/yr.

Imagine a virtual grid which matched renewable generation instantaneously to smart loads. Imagine 2 different smart loads; electrolyser or BEV charger. Which load can be sync’d 100% time on the virtual grid? Ans. Electrolyser. Which scales with lowest material requirements as annual kWhr of renewable grows? BEV: more kWhr = linearly more battery materials. Electrolyser: more electrolysers (kW) only to match peak growth; more kWhr=larger H2 storage.
