The e-bio: fuel cell running on bioethanol




by Obamot » 19/06/16, 15:22

The energy future will depend on hydrogen!

Just like Toyota with its Mirai, or Honda with its Clarity Fuel Cell, Nissan arrives with another solution, but similar in the sense that all these manufacturers can skillfully switch to new concepts of vehicles running on hydrogen, as soon as the production will have reached a profitable industrial stage having reached critical mass.

So the choice of Nissan only confirms this trend (click to enlarge)

Nissan wrote:Nissan Motor is currently studying the development of a solid oxide fuel cell (SOFC) system that generates electrical energy from bioethanol. The new system called e-Bio Fuel Cell - a world first for the automobile - has a SOFC-type fuel cell powered by bioethanol. SOFC is a fuel cell that uses the reaction of various fuels, including ethanol or natural gas, with oxygen to produce electricity with high efficiency.

The e-Bio Fuel Cell system produces electricity through the SOFC (energy generator) using bioethanol stored in the vehicle. It uses hydrogen transformed from fuel through a reformer and oxygen in the atmosphere, and produces an electrochemical reaction generating electricity used to propel the vehicle.
SOFC fuel cell system

Unlike conventional systems, the e-Bio Fuel-Cell system has solid oxide technology as a power source, offering better fuel efficiency to give the vehicle a range similar to that of petrol cars (more than 600 km). . In addition, the various characteristics linked to electric propulsion such as silent driving, linear starting and fast acceleration, allow you to enjoy the joys and comfort of a pure electric vehicle (EV).

Fuel cell systems use chemicals that react with oxygen, producing energy without releasing harmful byproducts. Bioethanol fuels, including those from sugar cane and corn, are widely available in countries in South and North America, and in Asia. The e-Bio Fuel-Cell system, using bioethanol, can offer an environmentally friendly alternative and create opportunities for regional energy production, while supporting the existing infrastructure.

When power is generated in a fuel cell system, CO2 is usually emitted. With the bioethanol-based system, CO2 emissions are neutralized in the growth process of the sugar cane that makes up the bio-fuel, which allows it to have a "quasi-neutral carbon cycle", with a slight increase in CO2 level.

In the future, the e-Bio Fuel-Cell system will become easier to use. For example, a water-ethanol mixture will be easier and safer to handle than most other fuels. And since this will remove the limitations of creating a whole new infrastructure, this mix has great growth potential.

Operating costs will be similar to or even lower than today's electric vehicles because the e-Bio Fuel-Cell system will respond to more customer requests, with a shorter refueling time, greater autonomy and a power range higher.

Hello !

I take care of the hvac-intelligence.fr site, dedicated to everything related to HVAC,

I come here after some research on the fuel cell.

In fact, we have released a complete super resource on fuel cells (rather focused on domestic micro-cogeneration), but we explain in detail how SOFC batteries work.

Here is the link, I think it may be useful to some of your readers: http://www.hvac-intelligence.fr/micro-cogeneration-pile-combustible/

See you soon :)

Hello,

First, the subject of this thread concerns a fuel cell for a motor vehicle, so the report is not well understood?

Next little question: How do you manage to write in your link, that a thermal efficiency of condensing boilers would be almost 90%. While the Carnot cycle in thermodynamics, tells us that the maximum theoretical yield cannot exceed 66% (of memory)?
I installed a condensing boiler and I can say that the gain was only 7 to 8% compared to the previous one which was already not so voracious.

Finally if we compare to the COP of a heat pump, you do not compare with the other micro-generation fuel cell heating alternatives nor give the slightest idea of ​​the operating costs and the means of supplying it, therefore one can hardly form an opinion.

And besides, your site seems to have nothing to offer !? :o After surfing a bit, it would be a gas consuming system!

the swagmartin site gives a lot of information on fuel cells and everything you need around ... my conclusion is the opposite of his: it is inefficient and more complicated than a good old combustion engine

an internal combustion engine is inexpensive, is available from multiple manufacturers, can run an alternator with high peak power so making self-sufficient electricity accepts unclean fuel without risk for the life

fuel cells theoretically have a yield that exceeds the maximum carnot yield ... but practically the real yield is not that good ... and when you don't have liquid hydrogen, the transformation of methane or ethanol to hydrogen makes a big loss of energy: the total output does not exceed that of a very good combustion engine

why so many crazy projects in cogeneration? I think only to maintain the idea that it is too expensive and too complicated and not to do it ... while the simple combustion engine is already available

to return to obamot's first message, what are the encrypted results? in general transformation of ethanol in hydrogen more fuel cell it is not glorious, but with passage in an additional battery, I am afraid that the result will be sad

Nissan is Renault, perhaps in a hurry / s to offer an alternative to the 3 other major japs, which are already positioned with sales offers!

But the main interest is to offer a vehicle compatible with the future supply of post-oil and IMHO.

The hydrogen will then be produced directly from solar C-PV or thermodynamic and there as you often say, no matter the yields, since there is enough Sun falling every day to meet all the global demand (except that as it stands there is no industrial production capacity on a very large scale)

there is still no good way to store and transport pure hydrogen

as long as you have to use liquid petroleum fuel or ethanol the internal combustion engine is the best way to use it

we do not store hydrogen but we know how to make synthetic fuel! the fischer tropsh synthesis was used in germany during the last war so it's not new! and it is still relevant with the GTL gaz to liquid method ... and once we have liquid fuel we use the simplest and lightest vehicle possible ... I don't think the solution is to put gas plants in vehicles

I will not say no.

Pure hydrogen can be produced by RES and stored on site.

As here in two forms: hydrogen confined, then mixed with Co2 which gives "green natural gas":

https://m.youtube.com/watch?v=THt_WVAlbV4

Or here in Co2 + HH = HCOOH = methanoic acid: https://fr.wikipedia.org/wiki/Acide_méthanoïque

In both cases it is interesting because we remove Co2 of the atmosphere.

Or here: https://www.econologie.com/jean-luc-perrier-hydrogene-solaire/#comment-241

If it has to be transported, it can be transformed into liquid form as formic acid or into methane, which amounts to doing what you say (conventional engine suitable for).

The HUGE advantage is that it can be distributed through an existing network, that of natural gas pipes. And there all the infrastructure already exists almost everywhere in urban and suburban areas and / or it is easy to extend ...

The fuel cell is interesting for autonomy in areas where one cannot easily recharge for lack of available infrastructure, so it seems complementary. (The Renault / Nissan option gives good flexibility) ...

German experience shows that they seem to have found two or three links missing from a transition to a 100% renewable energy world: storage + transport + distribution using an existing network ...! Not bad...

It's still at the experimental stage, because you still have to consume a lot of energy to carry out these transformations into formic acid or https://fr.wikipedia.org/wiki/Stockage_ ... C3.A9thane

Not that much, since it is to release it during use ...

remove CO2 from the atmosphere? there is too little of it, there is no energetically profitable industrial way to extract it

the only way to extract this CO2 is natural: photosynthesis, and in addition it does not only make CO2, it captures the energy of the sun to store it in the form of carbon

photovoltaic and photosynthesis are therefore complementary: photosynthesis to make carbon at low prices ... photovoltaic to make energy, and fischer tropsh synthesis to make synthetic fuel using biomass only for its carbon and using photovoltaic for maximum energy

the classic synthesis installations use carbon for everything, carbon and energy ... by using a maximum of another energy we reduce the carbon consumption

bizarre formic acid fuels are almost as complicated to manufacture as real synthetic gasoline, and its inefficient sound requires special engines ...
