My father has an idea to use sodium (Na) as fuel for fuel cells. This could easily replace batteries by having more or less instant reactions to demand, being much more energy dense and being simple to handle. Also, there is no CO_2 that would need to be captured compared to "bio" fuels. The resulting sodium hydroxide (NaOH) and hydrogen (H_2) can easily be used further e.g. in the chemical industry or recycled, electrolysis of NaOH is well known and also produces hydrogen as a byproduct. The resulting sodium metal can again be used as fuel. It creates a circular economy. Handling sodium securely at scale is also probably even easier than handling gasoline or diesel. Most of these reactions at industrial scale are more than 50 years old but nobody bothered to actually implement it (even though a hint about sodium cells for electricity generation is present in "Twenty Thousand Leagues Under the Seas: A World Tour Underwater" by Jules Verne already) instead of the more complex approaches like e.g. synthetic gasoline.
You can look at the orgpage about these ideas https://orgpad.com/s/energiewende https://orgpad.com/s/energiewende my father also gave a talk last week about it, there is a recording, which will be posted during the next days.

- willis936 6y agoMany years ago I briefly had a thought experiment about converting a gasoline/oxygen combustion engine into a sodium/water combustion engine. Solid fuel mixing concerns aren’t the primary issue. The primary issue is the energy density is just so danged low compared to gasoline. However, compared to electric batteries, sodium is far more energy dense.
- kaliszad 6y agoWell, there are patents for running diesel engines with sodium, at least I was told so much by my father who researched the problem thoroughly. The density isn't that low considering using a fuel cell, you can convert the energy a lot more efficiently. Also you don't just burn up the fuel into the air as currently, there is no industrial process to collect the CO_2 and other gases produced from the exhaust.
