Since 1999, when Iceland announced its plan to become the first hydrogen-based economy in the next 30–40 years, governments and businesses have begun to seriously consider the hydrogen option. In 2000, the small South Pacific island of Vanuatu joined Iceland in making steps towards widespread hydrogen use and deriving 100 percent of its energy from renewable sources. Hawaii, another island rich in renewable resources such as geothermal and wind energy yet still heavily dependent on oil imports, invested in hydrogen research in 2001, hoping to eventually export hydrogen to other states and nations. And California, the United States’ largest gasoline consumer, began developing the world’s first “hydrogen highway” in 2004. Hydro and Hydrocoin is going to be big!
