Hydrogen Production From Seawater and Wind

..."Hyundai believes that hydrogen fuel cell vehicles will play an important part in the mobility industry and at a recent event in Anaheim, California, showcased the commercialized version of the class 8 XCIENT fuel cell truck in the U.S. for the first time.

The automaker first launched the XCIENT fuel cell markets back in 2020 in Switzerland, Germany, Israel, Korea, and New Zealand and over the past three years, examples have been driven over a combined 4 million miles. The version displayed in California is the 6×4 variant that features a pair of 90 kW hydrogen fuel cell systems as well as a 350 kW electric motor. It has a driving range of over 450 miles (724 km) with a maximum 82,000 lbs (~37,000 kg) load."...

There's not much <...Seawater...> in <...Switzerland...>.

This looks like a more viable solution to trucking than an electric truck.

"BELLEVUE, Wash. and PLANO, Texas (May 2, 2023) – PACCAR and Toyota Motor North America, Inc. (Toyota) today announced an expansion of their joint efforts to develop and produce zero emissions, hydrogen fuel cell (FCEV) Kenworth and Peterbilt trucks powered by Toyota’s next-generation hydrogen fuel cell modules. The expanded agreement supports ongoing development and commercialized zero-emission versions of the Kenworth T680 and Peterbilt 579 models featuring Toyota’s hydrogen fuel cell powertrain kit, with initial customer deliveries planned for 2024."

Shouldn't that be OffsH₂Ore ?

..."A Bloom Energy solid oxide electrolyser has started hydrogen production at a NASA research centre in California, US.

The high temperature 4MW Bloom Electrolyser™ installation at NASA’s Ames Research Center in Mountain View is said to offer 20-25% more hydrogen per megawatt than commercially demonstrated lower temperature electrolysers such as PEM or alkaline.

Bloom says the electrolyser was built, installed and made operational in the span of just two months and will deliver the equivalent of over 2.4 tonnes days of hydrogen output.(that's per day)

It is hoped the demonstration will showcase the maturity efficiency and commercial readiness of Bloom’s solid oxide technology for large-scale clean hydrogen production."...

..."Results from the pilot revealed the electrolyser produced hydrogen at 37.7kWh per kg of hydrogen."...

,,,In electrical terms, the energy density of hydrogen is equal to 33.6 kWh of usable energy per kg,...the unit can ramp up from 5% to 100% in about 15 min with minimal loss of efficiency...

Ummmm.....500 bar pressure is 7,250 psig ... IMHO, few existing offshore systems can last a long time at this pressure.

Massive amounts of electrical energy will be consumed getting your hydrogen up to this high pressure. Huge, multi-staged compressors will be required -- operating in a highly corrosive environment. They will be very expensive and subject to destructive storms.

... and, I suspect, you advocate this high-pressure, never been done in the past, piping/compressor system just to make your CAPEX estimate look good

No ???

We're talking a lot of money here....cost of production ~$1.50 per kg... retail ~$16.00 kg

at 50k tonnes per year $75 mil cost = $800 mil revenue....

$1.50/kg to produce. Where did that number come from?

As well, just what does ‘produce’ mean?

How much does it cost to produce hydrogen?

"Depending on regional gas prices, the levelised cost of hydrogen production from natural gas ranges from USD 0.5 to USD 1.7 per kilogramme (kg). Using CCUS technologies to reduce the CO₂ emissions from hydrogen production increases the levelised cost of production to around USD 1 to USD 2 per kg."

So basically just an estimate considering the scale and wind produced electricity used in vertically integrated manner...now this is from natural gas and electrolysis is more expensive at this time according to est, but the efficiency is continuing to improve and by the time the plant is built it should be cheaper....but there are many moving parts and the figures quoted are just targets...

"How much will green hydrogen cost in 2023?

The International Council on Clean Transportation estimates that the IRA "can reduce the cost of green hydrogen production by almost half, falling to nearly $3 per [kilogram] hydrogen for a project starting in 2023." And the market trends are indicating this estimation to be accurate".Mar 6, 2023

DOE offers $750M to help drive clean hydrogen production costs down 60% by 2026

Well... okay.

As you say, many moving parts in this scheme. I know this post will paint me as the negative Nancy type, but I believe these numbers to be wildly optimistic. Multiply these projected costs by three, double that number twice, and you might be in the real ballpark.

Then we have to fill one of the eight dedicated cargo vessels with 400 ton of H2 - I propose vessels to be named The BLEVE Biden, The BLEVE Harris... anyway, steaming to unloading/storage facilities with, as you say, many moving parts. Distribution has many more moving parts (three, perhaps four tiers), as does dispensing at the end user locations.

I’ll be honest here: several dozens of the best engineers on the planet, governments and industry throwing hundreds and hundreds of millions of dollars around, all the hand wringing and wailing and Green Energy mantra chanting... and this is what we get? This particular observation can apply to the several Green Energy schemes on the boards.

And now for the really unsavory part. After this and varied other Green schemes are all online - say ten years - what will be the global average temperature in twenty years? Thirty years? Hundred years?

Well there's a lot that can be said here...for one thing I think we can reach these goals, but besides that the move to energy independence is important as resources become scarce, most wars have been fought over key resources, and that may never change, but the worldwide movement to make countries energy independent will certainly make a good first step towards world peace....

The further evolution of scientific knowledge and engineering expertise, materials research and other fields related to this movement is causing a resurgence in the science and engineering that the future is built on, it's creating good and interesting programs that are popular with today's younger generation which is reinvigorating pursuit of advanced education which leads to better jobs and better lives..

....as has been said before the journey is as important as the goals...

With computers, AI and worldwide collaboration ,technology moves faster than in the past... what used to take years now takes only months...You ask what will we have, what we will have is a machine that can solve nearly any problem, and with that comes peace and prosperity...Oh I'm not saying we won't have the occasional nutcase that has to be dealt with, but it becomes less and less over time...

Since a "concept," I won't hold my breath.

We always have to ask if that is "installed" power or "actual" power which is around 30% of installed.

So true, what it can produce, and what it does produce, can be 2 different things, and is usually the case when dealing with renewables...but still this is a pretty cool concept...

There are so many possibilities and ways to produce hydrogen....
