Hydrogen is the most abundant element on Earth. And it’s potential as a fuel could revolutionize the energy market because using it doesn’t produce any emissions. Zero. Unfortunately, it’s lightweight gas and rises into the atmosphere, which means its rarely found in its pure form. And making making it produces emissions.
