Â You might want to start saving those eggshells from your breakfast, they could help make hydrogen fuel.
While you’re probably not going to be able to make it at home, Engineers at Ohio State have been using eggshellsÂ to soak up carbon dioxide in a hydrogen-producing reaction. They explain that excess carbon dioxide has been a major problem, and have found that when the eggshells are ground-up, they can absorb carbon dioxide. The process is explained as follows:
That brought them to eggshells, which mostly consist of calcium carbonate — one of nature’s most absorbent materials. It is a common ingredient in calcium supplements and antacids. With heat processing, calcium carbonate becomes calcium oxide, which will then absorb any acidic gas, such as carbon dioxide.
The eggshells absorb up to 78% of the carbon dioxide, being the most effective carbon-dioxide absorber to date. The best part, eggshells are a 100% green material. No complicated or dangerous chemicals, no emissions. It’s a massively plentiful resource too, according to the ENN article, nearly 91 billion eggs were produced, which is about 455,000 tons of shell, that’s a heck of a lot carbon-sucking power!
Researchers came upwith another benefit of the shells as well, in order to use them for hydrogen production, that filmy layer on the inside of the shell has to be removed. They developed an organic acid to accomplish this and collect the collagen. This collagen can fetch big bucks , so in addition to producing hydrogen, we’ve got a great money maker too.
With hydrogen looking to become a major source of fuel in the near future, we could very well see eggs becoming pretty valuable, or maybe we’ll just have to sort our garbage for eggshells too!
…oh, and apparently eggs are good for you or something too….
