Finally, urine can also be used as a basis to generate hydrogen (which is an energy carrier).

This is used in hydrogen technologies to generate hydrogen as a fuel.

They generate hydrogen from their food and keep it under a slight pressure.

The amount of overcharging is usually very small and generates little hydrogen, which dissipates quickly.

However, the process used to generate hydrogen in a form useful to power trains does produce a small amount of greenhouse gases.

In 2009, cellulosic materials were first used to generate high-yield hydrogen.

In addition, some wastes generate hydrogen, which can burn or explode.

This is possible by using renewable energy to generate hydrogen by electrolysis of water.

This reaction provides a useful method to generate hydrogen in the laboratory.

Currently, we have the technology to generate hydrogen from coal, natural gas, biomass and water.
