hydrogen power [/move]

electrochemical device that can help make energy using sunlight
and water. Credit: Syed Mubeen.
University of Iowa researchers are working with a
California-based startup company to make clean energy from
sunlight and any source of water.
The university recently renewed a one-year research agreement to
further develop the technology with HyperSolar, a company that
aims to commercialize low-cost renewable hydrogen.
Hydrogen power is arguably one of the cleanest and greenest
energy sources because when it produces energy, the final
byproduct is water instead of carbon emissions. Hydrogen power
also can be stored in a fuel cell, making it more reliable than
traditional solar cells or solar panels, which need regular
sunlight to remain "on."
HyperSolar's lead scientist, Syed Mubeen, a chemical engineering
professor at the UI, says although hydrogen is the most abundant
element in the universe, the amount of pure hydrogen in the
Earth's atmosphere is very low (about 0.00005 percent), so it
must be produced artificially.
Currently, most hydrogen power is made from fossil fuels
HTML http://www.pic4ever.com/images/126fs2277341.gif
in a chemical
process called steam reforming, which emits carbon dioxide. Even
though the end product is hydrogen, its inputs make it much less
environmentally friendly and sustainable.
Hydrogen also can be made using electrolysis, which requires
electricity and highly purified water to split water molecules
into hydrogen and oxygen. Although this is a sustainable process
(assuming the electricity is produced from a renewable energy
source), the cost of materials associated with the system are
expensive—a major barrier to the affordable production of
renewable hydrogen.
"Developing clean energy systems is a goal worldwide," Mubeen
says. "Currently, we understand how clean energy systems such as
solar cells, wind turbines, et cetera, work at a high level of
sophistication. The real challenge going forward is to develop
inexpensive clean energy systems that can be cost competitive to
fossil fuel systems and be adopted globally and not just in the
developed countries."
With HyperSolar, Mubeen and his team at the UI's Optical Science
and Technology Center are developing a more cost-effective and
environmentally friendly way to manufacture hydrogen by drawing
inspiration from plants. So far, the researchers have created a
small solar-powered electrochemical device that can be placed in
any type of water, including seawater and wastewater. When
sunlight shines through the water and hits the solar device, the
photon energy in sunlight takes the water (a lower energy state)
and converts it to hydrogen (a higher energy state), where it
can be stored like a battery. The energy is harvested when the
hydrogen is converted back into its lower energy state: water.
This is similar to what plants do using photosynthesis, during
which plants use photons from the sun to convert water and
carbon dioxide into carbohydrates—some of which are stored in
fruits and roots for later use.
Mubeen says his team is currently working to lower costs even
further and to make their process more robust so it can be
produced on a mass scale. That way, it eventually could be used
as renewable electricity or to power hydrogen fuel cell
vehicles.
"Although H2 can be used in many forms, the immediate
possibility of this renewable H2 would be for use in fuel cells
to generate electricity or react with CO2 to form liquid fuels
like methanol for the transportation sector," he says. "If one
could develop these systems at costs competitive ;) to fossil
fuel systems , then it would be a home run."

Agelbert NOTE: Did you read that bit about how most hydrogen is
made from fossil fuels with steam forming? Here is something you
should know about steam forming, from an ERoEi standpoint:
--- Quote ---
> Hydrogen can also be extracted from hydrocarbons by reforming.
This chemical process is, in principle, an energy transfer
process. The HHV energy contained in the original substance can
be transferred to the HHV energy of hydrogen.
>
> Theoretically ;D, no external energy is needed to convert a
hydrogen-rich energy carrier like methane (CH4) or methanol
(CH3OH) into hydrogen by autothermal steam reforming.
>
> But in reality ;D, thermal losses cannot be avoided and the
HHV energy content of the original hydrocarbon fuel always
exceeds the HHV energy contained in the generated hydrogen.
>
> The efficiency of hydrogen production by reforming is about
90%. Consequently, more CO2 is released by this "detour" process
than by direct use of the hydrocarbon precursors. But no obvious
advantages can be derived with respect to well-to-wheel
efficiency and overall CO2 emissions.
--- End Quote ---
HTML http://www.afdc.energy.gov/pdfs/hyd_economy_bossel_eliasson.pdf
The only reason electrolysis, a truly clean way to generate
Hydrogen, is more expensive than steam forming, is because of
fossil fuel subsidies, NOT because of Energy Return on Energy
Invested (ERoEI) thermodynamics.
If the fossil fuel direct and indirect subsidies were eliminated
(even excluding the pollution costs), fossil fuel systems would
not be cost competitive with ANY Renewable Energy system.
Hydrogen power just needs the subsidy push that the fossil fuel
industry has always used to make its products be artificially
cost competitive with Renewable Energy technologies and
products, such as Ethanol from biomass.
In addition to Hydrogen production, the fossil fuel industry
also produces about 5% of the world's ethanol. This ethanol
takes far more energy to produce than biomass ethanol. But once
again, the unwarranted subsidies of the fossil fuel industry
enable it to produce a "cost competitive" ethanol, unjustified
from a thermodynamiics standpoint.
Biomass ethanol, unlike fossil fuel industry ethanol, is
justified from a thermodynamics standpoint. Producing hydrogen
or ethanol using fossil fuels is totally unjustified.
Subsidies for clean hydrogen production, like the photon
mediated production portrayed in the above article or
electrolysis and biomass based ethanol production are justified
when all the energy and pollution costs are considered.
--- Quote ---
> Between 1968 and 2000, oil companies received subsidies of
$149.6 billion, compared to ethanol’s paltry $116.6 million. The
subsidies alcohol did receive have worked extremely well in
bringing maturity to the industry. Farmer-owned cooperatives now
produce the majority of alcohol fuel in the U.S. Farmer-owners
pay themselves premium prices for their corn and then pay
themselves a dividend on the alcohol profit.
>
> The increased economic activity derived from alcohol fuel
production has turned out to be crucial to the survival of
noncorporate farmers, and the amounts of money they spend in
their communities on goods and services and taxes for schools
have been much higher in areas with an ethanol plant. Plus,
between $3 and $6 in tax receipts are generated for every dollar
of ethanol subsidy. The rate of return can be much higher in
rural communities, where re-spending within the community
produces a multiplier factor of up to 22 times for each alcohol
fuel subsidy dollar.

hydrogen and rechargable zinc batteries

sunlight and improve the performance of solar cells made of
bismuth vanadate (1μm=1,000 nanometers). Credit: Wei Chen
and Yongcai Qiu, Stanford [/center]
A Stanford University research lab has developed new
technologies to tackle two of the world's biggest energy
challenges - clean fuel for transportation and grid-scale energy
storage.
The researchers described their findings in two studies
published this month in the journals Science Advances and Nature
Communications.
[center]Hydrogen fuel[/center]
Hydrogen fuel has long been touted as a clean alternative to
gasoline. Automakers began offering hydrogen-powered cars to
American consumers last year, but only a handful have sold,
mainly because hydrogen refueling stations are few and far
between.
"Millions of cars could be powered by clean hydrogen fuel if it
were cheap and widely available," said Yi Cui, an associate
professor of materials science and engineering at Stanford.
Unlike gasoline-powered vehicles, which emit carbon dioxide
(CO2),[b] hydrogen cars themselves are emissions free.
[/b]Making hydrogen fuel, however, is not emission free: today,
making most hydrogen fuel involves natural gas in a process that
releases CO2 into the atmosphere. *
To address the problem, Cui and his colleagues have focused on
photovoltaic water splitting. This emerging technology consists
of a solar-powered electrode immersed in water. When sunlight
hits the electrode, it generates an electric current that splits
the water into its constituent parts, hydrogen and oxygen.
Finding an affordable way to produce clean hydrogen from water
has been a challenge. Conventional solar electrodes made of
silicon quickly corrode when exposed to oxygen, a key byproduct
of water splitting. Several research teams have reduced
corrosion by coating the silicon with iridium and other precious
metals.
Writing in the June 17 edition of Science Advances, Cui and his
colleagues presented a new approach using bismuth vanadate, an
inexpensive compound that absorbs sunlight and generates modest
amounts of electricity.
"Bismuth vanadate has been widely regarded as a promising
material for photoelectrochemical water splitting, in part
because of its low cost and high stability against corrosion,"
said Cui, an associate professor of photon science at the SLAC
National Accelerator Laboratory. "However, the performance of
this material remains well below its theoretical
solar-to-hydrogen conversion efficiency."
Bismuth vanadate absorbs light but is a poor conductor of
electricity. To carry a current, a solar cell made of bismuth
vanadate must be sliced very thin, 200 nanometers or less,
making it virtually transparent. As a result, visible light that
could be used to generate electricity simply passes through the
cell.
To capture sunlight before it escapes, Cui's team turned to
nanotechnology. The researchers created microscopic arrays
containing thousands of silicon nanocones, each about 600
nanometers tall.

Higashi [/center]
"Nanocone structures have shown a promising light-trapping
capability over a broad range of wavelengths," Cui explained.
"Each cone is optimally shaped to capture sunlight that would
otherwise pass through the thin solar cell."
In the experiment, Cui and his colleagues deposited the nanocone
arrays on a thin film of bismuth vanadate. Both layers were then
placed on a solar cell made of perovskite, another promising
photovoltaic material.
When submerged, the three-layer tandem device immediately began
splitting water at a solar-to-hydrogen conversion efficiency of
6.2 percent, already matching the theoretical maximum rate for a
bismuth vanadate cell.
"The tandem solar cell continued generating hydrogen for more
than 10 hours, an indication of good stability," said Cui, a
principal investigator at the Stanford Institute for Materials
and Energy Sciences. "Although the efficiency we demonstrated
was only 6.2 percent, our tandem device has room for significant
improvement in the future."
Rechargeable zinc battery
In a second study published in the June 6 edition of Nature
Communications, Cui and Shougo Higashi, a visiting scientist
from Toyota Central R&D Labs Inc., proposed a new battery design
that could help solve the problem of grid-scale energy storage.
"Solar and wind farms should be able to provide around-the-clock
energy for the electric grid, even when there's no sunlight or
wind," Cui said. "That will require inexpensive batteries and
other low-cost technologies big enough to store surplus clean
energy for use on demand."
In the study, Cui, Higashi and their co-workers designed a novel
battery with electrodes made of zinc and nickel, inexpensive
metals with the potential for grid-scale storage.
A variety of zinc-metal batteries are available commercially,
but few are rechargeable, because of tiny fibers called
dendrites that form on the zinc electrode during charging.
Theses dendrites can grow until they finally reach the nickel
electrode, causing the battery to short circuit and fail.
The research team solved the dendrite problem by simply
redesigning the battery. Instead of having the zinc and nickel
electrodes face one another, as in a conventional battery, the
researchers separated them with a plastic insulator and wrapped
a carbon insulator around the edges of the zinc electrode.
"With our design, zinc ions are reduced and deposited on the
exposed back surface of the zinc electrode during charging,"
said Higashi, lead author of the study. "Therefore, even if zinc
dendrites form, they will grow away from the nickel electrode
and will not short the battery."
To demonstrate stability, the researchers successfully charged
and discharged the battery more than 800 times without shorting.
"Our design is very simple and could be applied to a wide range
of metal batteries," Cui said.

Mormon farmers
have been running their tractors on it for at least that long.
While it is true that storing hydrogen, AS A GAS, is tough and
energy intensive, "storing" it as WATER, to be used when you
need it for a few hours from a solar powered electrolyzer, is
old hat, as long as the sun comes out that day. ;D
It's BULLSHIT to claim well insulated low temperature hydrogen
fuel tanks could not have been mass produced and economically
iincorporated into our vehicles by a country that pioneered the
technology for ICBMS, hydrogen bombs and the space shuttle.
And furthermore, if the nukers had allowed a certain isotope of
hydrogen to be used to produce a hydride that could economically
store hydrogen gas (at room temperature with zero leakage) in
SCUBA tank like bottles in a vehicle, we could all be running
hydrogen collected from a home solar powered electrolyzer in our
cars. A catalytic agent releases the gas from the hydride
gradually as needed to run your engine. And, by the way, your
risk of explosion and fire with this system is far lower than
with a gasoline tank.
It didn't happen because all those terrorists among us would run
out and make hydrogen bombs from heavy water... Fossil fuel
industry fuel product profits from 42% PLUS of their refinery
CRAP had, and has, nothing whatsoever to do with it. LOL!

This week, the German Aerospace Center (DLR) Institute for Solar
Research turned on the Synlight project, an array of 149 huge
spotlights. Together, these spotlights converge on a single
20-by-20 centimeter (8×8 inch) spot onto which it projects
10,000 times the amount of solar radiation that would have
normally shined on the surface. The researchers call it the
largest ‘artificial sun’, though we shouldn’t confuse it with
fusion energy projects which would be more deserving of the
title.

A huge
lightbulb

The setup is comprised of xenon short-arc lamps, which you’d
typically find in a modern cinema, arranged in a honeycomb
structure in Juelich, just 30 kilometers (19 miles) west of
Cologne. When the lights are turned on, an immense amount of
power is concentrated on a small surface, just enough to heat it
in excess of 3,000 degrees Celsius.
Unlike the sun, however, this project doesn’t create it energy.
Rather, it eats it with a voracious appetite. Turning on the
lights for four hours consumers as much electricity as a
four-person household does in a whole year. It might help
generate energy, though.
The goal of the project is to better understand solar radiation
dynamics to find out how to maximally exploit solar energy. For
instance, a setup similar to Synlight only comprised of mirrors
could be used to generate renewable liquid hydrogen, a fuel
which emits zero emissions when combusted. Right now, 99% of all
man-made hydrogen is derived from fossil fuels through an energy
and carbon intensive process called methane reforming.
Of course, hydrogen by itself is not without problems. Storing
it can be a hassle because it’s the lightest and smallest
molecule and just escapes most containers. It’s density is very
small which can also be problematic. However, combining it with
carbon monoxide results in eco-friendly kerosene for the
aviation industry.

Once scientists master hydrogen production with Synlight, they
can scale the system tenfold — all powered by the sun, not
electricity, this time.
The DLR labs are busy with other interesting projects. One of
them involves creating artificial comets made of water, rock
dust, and soot, all locked in a vacuum chamber that, of course,
contains an artificial sun.

You are welcome, Az. You know I have always believed hydrogen
powered vehicles are practical and cost effective. I have posted
here, years ago,about how a home setup of a solar powered water
hydrolyzer has been available for well over a decade.
Many people do not know, but I learned it when I researched it,
that most of the hydrogen production in the world is done by the
Fossil fuel Industry in a horribly inefficent process that
extracts the hydrogen from products of fossil fuel refining. The
"inefficiency" claim that fossil fuelers often wail and moan
about for the production of hydrogen from electrolysis is
hypocritical in the extreme, when their process is even less
efficient! They have to refine oil BEFORE they can get the
lighter products like methane (CH4) from the cracking towers to
the point where the process of chemically producing hydrogen gas
can begin. It is ruinously inefficient. It is ERoEI NEGATIVE!
Yet, the fossil fuel industry REFUSES to go for a
NON-hydrocarbon (i.e WATER) feedstock. So it goes. :(
Here's the deal with hydrogen. It's a pain in arse to store. It
leaks because it is so tiny. But, that isn't the biggest problem
with this massively high energy density gas (even though Hess's
"Law", oh so covenient for hydrocarbons, gives it a nominal
enthalpy value of zero - LOL!).
When hydrogen percolates through the metal in the container
housing it and through the pipe metal that feeds it to the
combustion chamber, this embrittles the daylights out of said
metal and deteriorates it. It is an issue, but one that can be
dealt with by replacing those parts most affected at specific
intervals. Nuclear power plants have a hell of problem with the
hydrogen isotope that plays embrittlement hell with all their
machinery and pipes.
All that said, the best way to use hydrogen as a fuel is to make
it just before you use it. That's where a home hydrolizer comes
in. That would threaten the bottom line of the Fossil fuel
Industry so it ain't happenin' any time soon, at least for the
average Joe or Jane.
These modern hydrogen fuel CELL type vehicles are high tech.
They are expensive. They are too expensive, as far as I am
concerned. However, if they ever go mainstream, you can bet your
bottom dollar that the Fossil Fuel Industry will be front and
center in the production and marketing of these high tech
vehicles that will need expensive routine maintenance and lots
of government subsidy to be "affordable" for the average Joe.
A Ford, off the shelf, engine was modified over 8 years ago to
run on hydrogen for the Phantom Eye drone. It was no big deal.
It was easy to do. Ford did not have to come up with some new,
"specialized for hydrogen combustion", engine.
They could have done the same for cars. They just did not want
to.

with the piston-powered Boeing Condor that set several records
for altitude and endurance in the late 1980s. Boeing also
studied a larger HALE UAV that can fly for over 10 days and
carry payloads of 2,000 pounds (900 kg) or more; the company
also worked on the Phantom Ray UAV as a flying testbed for
advanced technologies.[5]

cleared the way for the propulsion system and the airframe to be
assembled. Boeing worked closely with Ball Aerospace, Aurora
Flight Sciences, Ford Motor Co. and MAHLE Powertrain to develop
the Phantom Eye.[5] The Phantom Eye was revealed to the press at
a ceremony at Boeing's facilities in St Louis, Missouri, on July
12, 2010.[2] The Phantom Eye demonstrator is a 60%-70% scale
design of an objective system. According to Darryl Davis,
president of Boeing's Phantom Works advanced concepts group, the
Phantom Eye demonstrator could lead to an objective system
capable of achieving 24-hour-a-day, seven-day-a-week coverage of
an area year round with as few as four aircraft.[6]

2.3 liter engines, reduction gearbox, and 4-blade propeller. The
engines were originally designed for use with some models of the
petrol-burning Ford Fusion car. To be able to run in the oxygen
starved atmosphere at 65,000 ft, the engines featured a multiple
turbocharger system that compresses that available low density
air and reduces the radiated infrared heat signature to increase
its stealth properties. The engines, which provided 150
horsepower at sea level, were tuned so as to be able to run on
hydrogen. Boeing's marketing department stated that this will
make the aircraft economical and "green" to run, as the only
by-product would be water.[20]

I'll let you know about the H-tron and other hydrogen car
developments (They are up to something in South Korea right now.
They ordered several thousand hydrogen powered cars, not from
Audi.) when I read something substantial about a production
model. 8)

We shall see. Hydrogen powered cars are still a luxury vehicle
for the rich, as the Tesla Model S (and too many of the Model 3
dual motor models!).
I won't hold my breath waiting for Tesla to crater. That said,
the onslaught to ICE car sales coming from SEVERAL BYD cheap and
reliable EVs coming to the USA (that Warren Buffet is betting
on) will definitely smack Tesla's bottom line too. Musk wants
too much money for his EVs. If his profit margin is so thin that
he cannot compete with BYD's EVs, never mind the Volt or the
Bolt, Tesla will be absorbed by BYD or GM.

[center]Hyundai teams up with VW's Audi to boost hydrogen
cars[/center]
Costas Pitas 3 MIN READ
LONDON (Reuters) - Hyundai (005380.KS) agreed a deal with Audi
(NSUG.DE) on Wednesday to collaborate on hydrogen car
technology, hoping to boost an energy segment that has lagged
behind battery electric vehicles.
The South Korean firm wants to increase the uptake of hydrogen
cars, which are propelled by electricity generated by fuel cells
but have been held back by a lack of infrastructure and the push
for battery electric vehicles by the likes of Tesla (TSLA.O).
The pair will be able to access each other’s intellectual
property and share components, including any new parts developed
by Audi, which is responsible for hydrogen fuel cell technology
in the Volkswagen Group (VOWG_p.DE), the world’s biggest car
seller.
Hyundai hopes that the move will create greater demand for
vehicles such as its ix35 model and bring down costs to make the
technology profitable.
“We want to provide to our component suppliers more chance and
we want to have competition between component suppliers,” Sae
Hoon Kim, the head of Hyundai’s R&D fuel cell group, told
Reuters in an interview in London.
“We also want to make them to have competition with other
suppliers, and that competition will bring down the cost.”
Carmakers such as Toyota have touted the benefits of hydrogen
vehicles, which take less time to refuel than the recharge times
of battery electric cars, but are expensive and suffer from a
lack of refuelling stations.
Many carmakers are focusing on battery electric vehicles, which
can take between half an hour and half a day to recharge, but
are increasingly able to use a growing network of charging
points.
Auto firms are teaming up to share the cost of developing
greener technologies to replace combustion engines as regulators
around the world crack down on emissions. GM and Honda have a
partnership to jointly develop electric vehicles with hydrogen
fuel cells that are expected to go on sale in 2020, while BMW is
working with Toyota.
Kim said that a toughening of European Union carbon emission
limits in 2025 would create a need for more hydrogen cars.
Hyundai sold 200 such models last year and expects to sell
thousands this year, but Kim said profitability was still far
off.
“100,000 or 300,000 vehicles per year per company, when that
comes, I think we can make money,” he said.

I was perusing an encyclopedia (hard copy 2006 Annual New Book
of Knowledge) today and noticed a picture of a German submarine
launched in September of 2004 (page 67). It says that submarine
"gives off almost no pollutants" because it runs on HYDROGEN.
👀👍
Does anybody here know if it is still in operation? 🤔
It's only 15 years old.
Did it work out❓
If it did, why hasn't this hydrogen powered engine technology
become more common place❓
You don't build a submarine to be powered by HYDROGEN unless you
have a pretty sound idea of how durable this power system is,
especially if it is made by Germans.

Germany just ordered 27 more hydrogen trains to go with the 2
that are running now and France just ordered 17. 1,000 H2 trucks
are being built for Switzerland by Hyundai. Scotland has H2 bin
lorries.
Oh and a hydrogen drone just set a record with a 15 hour flight.
Why hasn't this tech become more common place? Because it is
going to change everything. It's the most disruptive tech the
energy sector has seen in hundreds of years. It's the end of the
petrodollar.
