Tpe alternative fuels help please

[gaya]

I would like to look for fuels such as hydrogen (very expensive) but ecological or like rapeseed which discharges can be more of co2 than gasoline but which makes profitable thanks to photosynthesis (yes because light + co2 = h2O + O2) So these fuels for me are non-fossil and clean. But for the plane I have heard of biokerosene and biofuel boat. What are good alternative fuels ???

listen stop telling anything and bump your subject:
rapeseed does not release more CO2 than petrol, read what I wrote to you otherwise it is useless

hydrogen requires nuclear electricity for its production therefore uranium which is fossil, otherwise it is made from petroleum therefore nrj fossil.

there is only hydrogen produced "on demand" which is worth it and produced on the alternator of vehicles ... clean?

hold a thread:
https://www.econologie.com/forums/electrolyse-amelioree-t1228-1860.html

on which we learn that hydrogen can be made from methane, precisely CH4 biogas which is 3000 times + harmful in terms of greenhouse gases!






but there is more simple: the BTL

So for you "non-fossil = clean" is that the basis of the subject?

biomass, wood, is it not clean?
and biogas then it is not clean?

bioessence = gasoline + fuel from biomass
biofuel = fuel oil + fuel from biomass
biokerozene = kerozene + fuel from biomass
biodiesel = diesel + fuel from biomass
wish it doesn't work for biogas ...

BUT IN WHAT PROPORTION? IN WHICH % ? 10%?
is this enough to make it a substitute fuel? 30 % ?
> no, you have to 100%!

bio-things are just basic things, requests to bioman

PS: we can make hydrogen from the sun

For agrofuels in my opinion it is above all a political problem.
example:
The Tarbes CCI promotes a recycling process for used cooking oils. A collector collects and recycles them.
Ok everything is fine.
It is after that things get complicated. The oils are recycled for cosmetics, and as fuel. But not for France, for Nordic countries.
Curious, right?

With regard to biofuels such as biodiesel, bioethanol, etc., this is only a transitional solution.
We will never be able to produce enough biofuel to run 100% on biofuel.
Biofuels will only be used as an additive to petroleum fuels (troll pet ) !!!

in any case it is not the fines for network pollution that have been distributed to professionals using frying oils, so far! ...
