The renewable energy hydrogen car: the future?

[sicetaitsimple]

With liquid nitrogen this will be possible, you will no longer need RTE, EDF or TOTAL.

The important thing is "your different roadmap", and the fact that you stick to it ......

[Obamot]

At the individual level if you put photovoltaic panels and use the Electric car to light you up at night, in winter you will not have heating, with hydrogen the efficiency will not be very good and it's not tomorrow that you can produce your own hydrogen, compress it, store it and fill the tank of your vehicle. With liquid nitrogen this will be possible, you will no longer need RTE, EDF or TOTAL.
I would be in their place, I would have done studies on liquid nitrogen as a means of storage, and I would be careful not to disclose them ... now that liquid nitrogen is protected by a patent. All they can say is that in 20 years time other technologies will appear and that in the current state of their knowledge hydrogen seems to be the best solution for 2035 or 2050. They are not in no hurry any more than the automakers. Global warming is not their priority. [...]

I have a different roadmap.

And why don't you go to a global scientific center, completely independent and secure, like EPFL which tests all kinds of things, in order to validate your project officially and on the international scene? Do you have accurate returns and experts who find things you may not have thought of yet?

They work WITH “start ups” and all kinds of companies!

I suggest that posts specifically "liquid nitrogen" come back to the dedicated thread and its already 55 pages.

good advice.

because frankly Eric, repeating your ideas on all subjects of econology does not get you anywhere.

and all alone with your little prototypes, I have doubts that you will succeed. No contempt on my part. Getting closer to engineering schools is a reasonable path because you risk colliding with multinationals, although Liquid air, anyway, would be "ZE French Spécialiste" on the subject ...

Air Liquide works more on hydrogen than on liquid nitrogen in my opinion. But someone has to tell them that they are wasting their time and that this is not the future, the subject of the post here. But if there were to be hydrogen pumps to recharge the tanks, the first customer could be the liquid nitrogen car, because a liquid nitrogen engine is more efficient than a fuel cell.

and concerning the liquid nitrogen engine it is not Air Liquide which has the patent, it is me Eric Dupont the great specialist of the liquid nitrogen engine..You are therefore mistaken to think that it is Air Liquide, you seized the difference, it's not me who collides with airliquide, but Air Liquide collides with me.

But in the context of hydrogen, EPFL has developed technologies with yields below expectations (far below the gross potential), just for reasons of storage safety. Like a fuel cell where hydrogen is drowned in formic acid:

A fuel cell based on formic acid

Scientists from EPFL and the GRT group built the first unit capable of producing electricity from formic acid using a fuel cell, and this in an energy efficient manner, safe, economical and renewable.

Do not forget that we will forever talk about an “energy mix”, so your system has its chances no matter how efficient it is.
So why avoid this possibility ???

I think that for a hydrogen car using a fuel cell or a liquid nitrogen engine, it is easier to compress hydrogen in a carbon fiber tank at a pressure of 700 bar than using l acid or hydrogen in another form; because the hydrogen car problem seems to me to be more in the pile than in the means to store the hydrogen and distribute it.

And the EPFl Eric? Are you going to contact them or continue moping?

I was talking earlier about ammonia, but formic acid is another candidate. It is as dangerous as ammonia (level 3), but 40 times less odorous. Just as ammonia has a characteristic odor at a very low concentration (0,04 ppm), so much formic acid has a less recognizable odor.
The advantage of formic acid is that you can capture the CO2 in the stack to sequester it.

Hydrogen is a good vector for transport but not in a 700 bar cylinder ...

Fortescue adds hydrogen-powered coaches at Pilbara

MINING.COM Staff Writer | August 17, 2020



Hydrogen-powered coaches will be added to Fortescue Metals fleet at its Christmas Creek operations in the Pilbara in a step to meet the company's zero operational emissions target by 2040.

According to the iron-ore major, the A $ 32 million renewable hydrogen mobility project - the first for an Australian mining operation - will see the deployment of 10 full-sized hydrogen buses, custom built by HYZON Motors, to replace the existing fleet of diesel coaches from mid-2021.

The project will be supported by the installation of a refueling station, which will harness renewable electricity from the Chichester Solar Gas Hybrid Project to generate renewable hydrogen onsite.

“This project represents a first step towards decarbonizing our mobile fleet, which is an important part of our goal to achieve net zero operational emissions by 2040.” Fortescue deputy CEO Julie Shuttleworth said.

“Fortescue's history of developing and adopting innovation and technology has been key to achieving our industry-leading cost position and we are applying this technology-first strategy to our hydrogen initiatives to ensure we remain at the forefront of this emerging industry.

“Fortescue's mobile fleet represents around 400 to 450 million liters of diesel consumption per year and presents a significant opportunity for hydrogen to be used as a replacement fuel source to accelerate emissions reduction and diversify our energy mix,”

Fortescue has received A $ 2 million in funding through the Western Australian Government's Renewable Hydrogen Fund to support the development of this project.

In April 2020, Fortescue and ATCO Australia (ATCO) entered into a partnership to build and operate the first combined hydrogen production and refueling facility in Western Australia. The facility will initially provide Fortescue, ATCO and approved third parties with the opportunity to refuel hydrogen vehicles.
