New fuel made from scrap aluminium delivers twice the energy of diesel

[Redaktion]

A new eco-friendly fuel, produced from aluminium, stores more energy than batteries and can be obtained from scrap metal. This recycled energy source would otherwise go to waste and can be used in the transport sector to reduce emissions.

I was working on this same idea but couldn't get anyone interested in participating in the project. Generating H2 from a chemical reaction with aluminum provides a great opportunity for generating green hydrogen.

I was working on separating hydrogen and oxygen from water but the opposition from the government was brutal.  They can't tax something that they don't control the delivery of.

I don't understand why people want to destroy something which can be reused. Surely a better use for waste aluminium would be to melt and remold into a new product. If you convert it to energy what are the by-products? What is left after conversion?

Considering the price of Aluminum these days and the fact it is 100% recyclable, this makes no sense at all.

I thought they made new cans out of the recycled aluminum.

Did you all not read the article  becouse what it says is that when they recycle aluminum there is a bye product  left over like diesel  with gas that is a un taped market  for a cleaner and more efficient  energy  solution

Aluminum is incredible amounts of embodied energy, this is true. But it got that energy through heat and direct combustion. It's an infinitely recyclable material and takes so much energy and carbon dioxide to make, that "burning" it is such a waste.

The way to refine Aluminum to remove its oxides is by introducing carbon, which produces carbon dioxide as a byproduct. This has to be done at high temps, and directly consumes energy to run the process. So, even if we could 100% electrify the grid, it would still require carbon dioxide emissions to produce aluminum.

What other by products does the reaction leave? Is there something besides aluminum hydroxide and hydrogen left behind. I'm sure the process produces heat too. Is there a way we can use thermal electricity production with the the reaction to make the process self reliant?  So many more questions here.

Very confusing article for readers who have no particular knowledge of the process. I would have provided basic process information.

The article says that scrap aluminum ends up in landfills, because industry can't ship it efficiently to a customer. Making it into fuel is a better plan B than the landfill. Also No it doesn't need to be melted to extract Hydrogen. It's by chemical reaction. It's like when an Alca seltzer hits water and releases carbon dioxide.

I got a US issued patent on using Al with an inert catalyst to split water into H2, Al(OH)3 and heat back in 1982
