The 2011 Fukushima nuclear disaster increased the need to find other sources of energy that are safer, less destructive and more efficient. With the better-known renewable sources of energy, such as solar, geothermal and wind energy, another relatively clean form of energy transfer and storage is being explored in Japan — hydrogen fuel cells. The government and industry should continue exploring ways to develop the infrastructure necessary to utilize hydrogen fuel cells, despite the many difficulties involved.

Hydrogen has potential for a number of reasons. It is abundant and easily combines with other elements. It is already present in many of the most important organic compounds. It is relatively easy to separate from other hydrocarbon compounds, and the combustion of hydrogen releases a high amount of energy.
