Hydrogen is found in abundance at the bottom of the ocean in frozen gas hydrates (see below).
Hydrogen is in natural gas, petroleum, and the byproducts of microbial activity. Hydrogen isn’t
limited to a few geographic regions of the planet, and that makes it a resource that automatically
reduces geopolitical tension over the control of limited oil resources.
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.
