Biohydrogen

Biohydrogen is like a magic gas that comes from tiny living things like bacteria. Bacteria are very small creatures that you can't see with your eyes but they can make something called energy by breaking down things like sugar. Just like when we eat food, we get energy to run and play, bacteria also eat and get energy to do their job.

When some types of bacteria eat, they produce a gas called hydrogen as their waste product. This gas can be collected and used for lots of things like power plants, fuel for cars, or even to make electricity. This is helpful because we want to use more clean energy and less fossil fuels that hurt the Earth.

So, biohydrogen is just like a magical gas that comes from bacteria eating and it can help us make clean energy!
