Formic acid is a very strong and very sour chemical that can be used to store energy for cars that run on electricity. Just like how your toy car needs batteries to run, electric cars also need some way to store energy. Think of formic acid like a gas tank that holds fuel for a car, but instead of gasoline, it holds formic acid.
The formic acid is stored in a tank in the car, and when the car needs power, it goes to a special machine called a reformer. This reformer takes the formic acid and turns it into electricity that can power the car's motor. It's like how your mommy uses a stove to cook food, but instead of food, the reformer makes electricity.
When the formic acid is turned into electricity, it releases another chemical called carbon dioxide. Carbon dioxide is a type of gas that's all around us – when we breathe, we breathe in oxygen and breathe out carbon dioxide. So, just like how you need to breathe, the car needs to let out carbon dioxide.
The cool thing about formic acid as a vehicle is that it's a very clean energy source. It doesn't release harmful pollutants that can harm the planet, like regular gasoline-powered cars. That's why some people think that formic acid vehicles could be the cars of the future!
