Hydrogen is clean: Through fuel cell technology, hydrogen can be converted to electricity with no harmful waste products. Hydrogen doesn't pollute cities, rivers, streams or oceans. Hydrogen doesn't cause global warming. Shifting to a hydrogen economy could save millions of lives each year in terms of human health effects alone, not to mention its effects on the health of the planet and its various forms of life.
Gas hydrates are abundant: At the bottom of the colder regions of the world's oceans, gas hydrates are plentiful. These are frozen ice-like crystals of frozen hydrogen. They're found off the coasts of Canada, Japan, Alaska, Russian, China, Iceland and the countries of Northern Europe. Technology now exists to harvest these gas hydrates, store them at liquid nitrogen temperature, and easily convert them into usable hydrogen gas by allowing them to melt at normal atmospheric pressure. The entire process is clean, energy efficient, and technically feasible. The available supply of gas hydrates is enormous, far exceeding the known supplies of all fossil fuels on the planet.
Hydrogen is renewable: Unlike fossil fuels, hydrogen is renewable. Converting hydrogen gas to electricity in fuel cells doesn't "destroy" the hydrogen; it just alters the state of the hydrogen. As a result, hydrogen molecules can be used over and over again to store and release electrical potential. For example, solar panel electrodes immersed in water cause the water to give off hydrogen gas. When that hydrogen gas is fed into a fuel cell, the byproduct is water. No hydrogen is destroyed in the process, it is simply transformed. In this way, hydrogen operates like a battery that transforms energy from the sun into usable electricity. This is just one of many examples of a hydrogen energy cycle that produces usable electricity.
Hydrogen solves serious global problems
By shifting to a hydrogen economy, we will simultaneously solve a long list of problems tied to the oil economy (pollution, limited resources, global warming, etc.) while creating new opportunities with hydrogen (clean, renewable, plentiful energy).
Applications for hydrogen are widespread: automotive (hydrogen powered fuel cell vehicles), industrial (hydrogen powered factories), municipal (powering cities with large-scale hydrogen power plants) and residential (home-based hydrogen power plants that convert natural gas to electricity).
