New hydrogen tank break through
Jun 4th, 2019 at 7:44pm
 
The grotty inconvenient dangerous unsafe pollution spewing Electric Cars just moved a step towards the junk yards.

The HYDROGEN BEHEMOTH which can power big and small vehicles with quick refuel will eventually make the electric lithium death traps obsolete soon.

Better storage might give hydrogen the edge as renewable car fuel
Nadine Cranenburgh   May 29, 2019

...
New sensor could make hydrogen-powered cars safer

In the race for greener fuel, a major roadblock for hydrogen is the need for safer, more economical storage. Researchers in the United Kingdom have discovered a material that could make this possible.
For cars powered by hydrogen gas, the cost and size of storage tanks that can achieve a similar driving range is much greater than those powered by liquid fuels such as petrol.


This means the tanks required by hydrogen-powered vehicles designed to travel long distances without refuelling are prohibitively large and heavy.

Another drawback is that it is difficult to store hydrogen for transport as a potential fuel export.

In the quest for more compact storage, car manufacturers have tried several different tacks.

These have included high pressure tanks, and dropping the temperature for cryogenic storage of liquid hydrogen. But these systems are complex to operate, and have potential safety risks.

Systems that store hydrogen as liquid ammonia or formic acid are also under development.

Professor David Antonelli from Lancaster University has recently discovered a material that he says could allow existing tank sizes to fuel four times their current range.


“The real advantage this brings is in situations where you anticipate being off grid for long periods of time, such as long-haul truck journeys, drones, and robotics. It could also be used to run a house or a remote neighbourhood off a fuel cell,” said Antonelli.

Take the pressure down
A study recently published in Energy & Environmental Science describes how Antonelli used a “molecular sieve” to bind hydrogen, thanks to a chemical process that moves the two molecules further apart without breaking the bond between them. This is known as Kubas binding.

This process is reversible, takes place at room temperature, and uses much lower pressures than existing storage methods.

To compare, the new material stores hydrogen at 120 bar (12 Mpa), which is less than the pressure of a scuba tank. Existing tanks use storage pressures of 700 bar (70 MPa).

The researchers also claim that the material absorbs and stores excess heat, so the tank would not need external cooling or heating.

Molecular sieves made from the material, known as Kubas Manganese Hydride-1 (KMH-1), could be installed inside hydrogen storage tanks onboard vehicles such as cars, trucks and trains. When the storage pressure is dropped, hydrogen could be released to feed a fuel cell and power the vehicle.

Boost over batteries
Antonelli believes the low manufacturing cost and high energy density of his new material will help hydrogen-fuelled cars give electric vehicles a run for their money.

“The cost of manufacturing our material is so low, and the energy density it can store is so much higher than a lithium-ion battery, that we could see hydrogen fuel cell systems that cost five times less than lithium-ion batteries as well as providing a much longer range — potentially enabling journeys up to around four or five times longer between fill-ups,” Antonelli said.

The promising new material has been patented by the University of South Wales and licensed to Kubagen, a company co-owned by Antonelli, with a view to refining and scaling up for commercial applications.

As soon as the looney Greenies like Tweedledee smell HYDROGEN they go berserk.

When will ScoMo swing the subsidy away from the renewable rubbish onto the HYDROGEN FUTURE FUEL ?

https://www.greencarreports.com/news/1123449_hydrogen-supply-pinch-affects-san-f...

Hydrogen fuel-cell drivers in California’s San Francisco Bay Area may soon have to find a backup plan—like a gasoline or electric vehicle.
As of Wednesday night, 9 out of the 11 passenger-vehicle hydrogen stations in the Bay Area were down due to a hydrogen shortage—a status that remained the same going back to Monday. An explosion on Saturday, June 1, at a facility owned and operated by the chief hydrogen supplier for the region, Air Products and Chemicals Inc., is related to that shortage.

This is a critical issue for drivers of fuel-cell vehicles as they rely on the (very limited) hydrogen infrastructure. If that infrastructure goes down, drivers are simply out of luck.

Those with battery electric vehicles, on the other hand, have options. If they can’t charge up at home, they can fast-charge along the way, or connect to a Level 2 AC charge point at work or while shopping—or as a backup, at pretty much any AC socket along the way if they’re willing to wait all day or overnight.

Hydrogen just got dropped by Toyota as well, in their new 30 year plan on changing over to electric vehicle's….. Wink

Electricity infrastructure is everywhere and almost everyone has a power point at home they can use to charge up an EV. I say almost everyone except for socko who still uses oil lanterns Cheesy LOL

Like I pointed out so correctly, as soon as the looney Greenies like Tweedledumb and Tweedledee smell HYDROGEN they go berserk.

It makes their Child's Minds that never developed in their Adult Bodies bounce around inside the vacant space between their ears.

Whatever will these inadequate creatures that can't compete in the human race be like when they are exposed to 5G death rays ?

When will ScoMo swing the subsidy away from the renewable rubbish onto the HYDROGEN FUTURE FUEL ?

While the dangerous unsafe pollution spewing all electric piles of junk have reached a dead end, the future for the real future fuel HYDROGEN burns brightly.

Hydrogen can be used to store the erratic energy produced from unreliable renewable rubbish.





Hydrogen: fuel of the future?
by Vicky Anning, Cambridge University Press FEBRUARY 6, 2018

...
As the race to find energy sources to replace our dwindling fossil fuel supplies continues apace, hydrogen is likely to play a crucial role in the future. Credit: Materials Research Society

Japan has already announced its intention to become the world's first "hydrogen society" - aiming to open 35 hydrogen fuelling stations by 2020. While Japanese car manufacturer Toyota expects 30 percent of its vehicles to be powered by hydrogen by 2050.

In a recent issue of MRS Energy & Sustainability, published jointly by the Materials Research Society and Cambridge University Press, scientists argue that sustainable, carbon-free methods of large-scale hydrogen production are the best way to prepare for our looming fossil-fuel free future (today hydrogen is producing from natural gas, generating large amounts of Carbon as side product).

Since water is the only bountiful source of hydrogen on the planet and sunlight is the most abundant energy source, global experts argue that solar-driven water splitting may become the technology of choice in the second half of this century - using sunlight to produce hydrogen from water.

However, the authors of three different papers focusing on the future of hydrogen suggest that significant research efforts and breakthroughs are urgently needed to help produce hydrogen on a suitably industrial scale that's fit for the 21st century and beyond.

...

Roel van de Krol from the Institute for Solar Fuels in Berlin and Bruce Parkinson from the University of Wyoming share their views that the current production processes for hydrogen using photovoltaics and wind-powered electrolysis are likely to dominate for the next few decades. But, they suggest, the next logical step is to integrate light absorption and catalysis in 'direct' photoelectrolysis routes. This would offer several advantages, they argue - including lower densities and better heat management.

In her paper, Katherine Ayers from Proton OnSite in Connecticut agrees that urgent action is needed. The realities of product development timelines dictate that existing commercial technologies such as low-temperature electrolysis will have to serve the majority of our needs for at least the next 20 years, she writes. However, to accelerate the impact of fundamental work in long-term technologies, she says that improved collaboration between researchers across academic, government and industry sectors is essential - to inform basic research as well as to leverage technology breakthroughs to help find solutions to our planet's looming fuel supply problems.

Last but not least, Artur Braun from the Swiss Materials Research Institute, EMPA shows us that science can always surprise us, even in an area where we think we know everything there is to know; he and co-author Qianli Chen give us a glimpse in their paper of a remarkable finding on how protons (hydrogen ions) can move through solids - a possible breakthrough for the future hydrogen economy.

Dangerous unsafe pollution spewing all electric toy cars have tanked as they clearly are not able to replace good solid reliable petrol and diesel vehicles.

Batteries can only power small toy cars so what about the many millions of large diesel powered vehicles and mining and manufacturing machines ?

This is where HYDROGEN steps in and elbows the rubbishy all electric toy cars aside.

When will ScoMo switch the subsidy being wasted on renewable rubbish which is a waste of white elephant money to HYDROGEN ?






The International Energy Agency (IEA) highlights that only three of twenty-six low carbon innovation areas - solar PV and onshore wind, energy storage and electric vehicles (EV) - are mature, commercially competitive and on track to deliver their share of the climate objectives set out at the 2015 Paris Climate Conference.

It is unlikely we can squeeze more out of these three technology areas than is currently projected. Solar PV and onshore wind are intermittent, so need to be used in conjunction with energy storage or other forms of power generation. The high-energy-density batteries that are used for both storage and EVs are causing concern around whether the supply of raw materials needed to manufacture them will be able to keep pace with their rapid uptake. According to BNEF, graphite demand is predicted to skyrocket from just 13,000 tons a year in 2015 to 852,000 tons in 2030, and the production of lithium, cobalt and manganese will increase more than 100-fold. This is already creating pressure on supply chains and prices - and on the people working in these mines, often in incredibly poor conditions.

Growing demand for EV batteries has caused a surge in demand for their raw materials.
                         
So what other options are available to us? The World Economic Forum’s latest white paper proposes some bold ideas to significantly accelerate sustainable energy innovation and support the uptake of future energy sources. One energy vector mentioned there that is often forgotten is hydrogen.

Hydrogen’s potential

Hydrogen has the potential to decarbonise electricity generation, transport and heat. That’s because when produced by electrolysis - using electricity to split water (H2O) into hydrogen and oxygen - hydrogen does not produce any pollutants.

Perhaps the best-known use for hydrogen currently is in transportation. With electric vehicles, drivers are often concerned about their range and the time it takes to recharge. Fuel cell electric vehicles, which run on hydrogen, avoid these concerns, as they have a longer range, a much faster refuelling time and require few behavioural changes.

Hydrogen can also be used to heat our homes. It can be blended with natural gas or burned on its own. The existing gas infrastructure could be used to transport it, which would avoid the grid costs associated with greater electrification of heat.

Once produced, hydrogen could also act as both a short and long‐term energy store. Proponents suggest that surplus renewable power – produced, for example, when the wind blows at night – can be harnessed and the hydrogen produced using this electricity can be stored in salt caverns or high-pressure tanks. Earlier this month a report by the Institution of Mechanical Engineers called for more demonstration sites and a forum in which to discuss hydrogen’s long-term storage potential.

If you are stupid enough to pay for it then you deserve to get ripped off. The smart ones will be charging up their EV's for free from their own rooftop solar Wink

If I am not the only one here who has run a process that strips hydrogen from other gasses please speak up.

We used a system of cryogenics to separate the different gasses to produce a 95% hydrogen stream. To oversimplify the process you might have noticed that when you use canned air to blow the cookie crumbs out of your key boards that the can becomes cold.

Quote:
The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under the right conditions, this can cause cooling of the fluid.


https://cryogenicsociety.org/resources/defining_cryogenics/joule-thomson_effect/

The other method is to strip the hydrogen from natural gas with steam.

Hydrogen is the lightest gas, is odorless and burns with an invisible flame in daylight. The test to determine if using hydrogen for fuel is to add up the cost to produce it compared to others. The upside is the exhaust is harmless water vapor.

Doesn't matter what Australia innovates.
It won't be allowed to allow Australians to 'get ahead' in the world.
Everything gets given to the USA first and anything with-held against their ownership (or even Britains) is deemed 'National Security Risk'.

MD, there is a vast amount of research going on solving the practical parts of the whole HYDROGEN FUTURE FUEL puzzle.

A lot of research is going on on how to extract Hydrogen from water.

There are systems already working overseas but to become successful commercially a bit more work is required.

But you can be certain it is coming.

See batteries can only be used to power toy cars and are too small to be used to power large diesel machines whereas hydrogen works quite well in large machinery. And is quick to refuel.

The impetus for hydrogen is the eventual end of oil.  Japan is going all out to swing over to hydrogen.
