Hydrogen – the Fuel of the Future?

Hydrogen – the Fuel of the Future?

Using fossil fuels to generate hydrogen can result in modestly lower emissions of CO2 and other pollutants than using these fuels as conventional energy sources, though this depends on the efficiency of the technologies involved. In order to get larger reductions, the CO2 must be captured and sequestered, a process that remains experimental and expensive. However, when the hydrogen separation process is based on renewable energy sources, hydrogen use is essentially pollution-free, with the only byproducts being water and heat.
