Hydrogen power is gaining momentum, but critics say it's neither efficient nor green enough
Hydrogen is the simplest element, and the most abundant substance in the universe.
When hydrogen burns, it generates energy in the form of heat, and the only by-product is water. That means energy created from hydrogen generates no atmosphere-warming carbon dioxide, making it one of many potential energy sources that could help reduce carbon emissions and slow global warming.
But creating hydrogen and transforming it into a useful format requires energy — and that energy is not necessarily renewable. That process is also inefficient and expensive compared with other forms of energy, renewable or not. Many critics say the hydrogen industry a way for oil and gas giants to stall the adoption of pure renewable energy sources like solar and wind, giving them a "green" cover while still maintaining demand for their products.
Despite the debate, companies and the U.S. government alike are pushing forward the continued development of the hydrogen industry.
