In summary, the conversation discusses the possibility of storing hydrogen in aerogels and potential methods for releasing the hydrogen. The cost and practicality of using aerogels for hydrogen storage is also mentioned. Various properties and materials are considered, such as platinum nickel and polymeric foam, and the conversation ends with the suggestion of using a specially designed carburetor for the process.

Does anyone know if it is possible to store hydrogen in aerogels?
 
Chemistry news on Phys.org

If so, is there a known catalyst that will free the hydrogen?

Yes, but it would not likely retain the hydrogen very long or at all. Hydrogen can diffuse through solid metal, hydride technologies are a much better option. If you were to use aerogel you would probably have to inpregnate hydrogen into it, seal it, seal it again, then to release it you would have to dissolve the sealent, and place it under a vacuum to get all the hydrogen out, good idea though.

Aerogel is better suited to applications like supercapicators, thermal insulation ect.

I have been trying to devise a possible outcome where it would be possible to apply 8.2Kg or there abouts into an aquivilant to 60 Litre tank or cell. Depending on design requirements. I have looked into the properties of Hydrogen and it's retention properties with applications such as diamond film studied by Schulich Faculty of Chemistry, Technion-Israel Institute of Technology, various metal alloys studied by various universities and even research by the Oiho University of a form of Polymeric foam which was partially funded by DaimlerChrysler to understand the most effective method to date.
To date I realize that the best form of conductive metals available is platinum nickel which produces the most amount of Hydrogen while conserving the most energy.

So I thought perhaps with aerogel having an awesome property which would allow 95-99% storage capacity for hydrogen gas being as mentioned above inpregnated into the aerogel, it would have the most logical application for Hydrogen.

Problem is of course aerogel is very costly at the moment to produce until it's application for other areas are realized by industry and also I haven't heard of anyone trying this as yet for a hydrogen application.

Any ideas?
I like the idea of the sealant and applying a kind of vacuum to it, perhaps a carborator could achieve the vacuum?

Cheers

Have chunks of hydrogen impregnated aerogel in a holding container with an auto feeding system into a basin of solvent with a vacuum drawn on it. After so long the spent aerogel, still under a vacuum, go to a separate holding container to be recharged later. The sealnt would need to be a material that would dry hard and strong yet when dissolved not form a gel, or a sticky mess when you want to change it out.

A specially designed carburator would be the best but a regular carburator, provided some holes are pluged, would work.

1. What is aerogel?

Aerogel is a lightweight, highly porous material that is composed of 99.8% air and 0.2% solid material. It is often referred to as "frozen smoke" or "blue smoke" due to its translucent appearance and low density.

2. How is aerogel made?

Aerogel is typically made through a process called supercritical drying, where a gel material is placed in a high-pressure chamber and subjected to supercritical conditions (high pressure and temperature). This process removes the liquid from the gel, leaving behind the aerogel structure.

3. What are the main applications of aerogel?

Aerogel has a wide range of applications, including insulation, soundproofing, and as a lightweight alternative to traditional building materials. It is also used in aerospace and military technology, as well as in scientific research and development.

4. What are the advantages of using aerogel?

Aerogel has many advantages, including its extremely low density, high thermal and acoustic insulation properties, and its ability to withstand high temperatures and pressures. It is also non-toxic and environmentally friendly.

5. Can aerogel be used in everyday products?

Yes, aerogel is becoming increasingly popular in everyday products. It is used in clothing and footwear for insulation, in cosmetics for its lightweight and absorbent properties, and in electronics for its thermal insulation and shock absorption capabilities.
