Renewable Energy : Hydrogen

Hydrogen Power and Fuel Cells
Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution.

Wikipedia: Hydrogen vehicle
A hydrogen vehicle is a vehicle, such as an automobile or aircraft, which uses hydrogen as its primary source of power for locomotion. These vehicles generally use the hydrogen in one of two methods: combustion or fuel-cell conversion.

The Hydrogen Fuel Cell Institute
A portal for clean energy and fuel cells.

Hydrogen - Energy
Hydrogen is the simplest element known to humans. Each atom of hydrogen has only one proton. It is also the most plentiful gas in the universe. Stars are made primarily of hydrogen.

Hydrogen Information
Hydrogen is often advocated as an energy medium. Here are some relevant facts.

Upper Midwest Hydrogen Initiative
The Upper Midwest Hydrogen Initiative is among the first regional, public-private hydrogen partnerships in North America. UMHI is an industry-led venture of the Great Plains Institute dedicated to accelerating the commercialization of hydrogen.

Hydrogen and Fuel Cell Safety
A monthly electronic publication of the National Hydrogen Association, with information on Hydrogen and Fuel Cell Safety, Codes and Standards.

Hydrogen Now!
The mission of Hydrogen Now! is to accelerate the use of renewable hydrogen. We have the technology to begin making a transition now.

Hydrogen Technologies
Hydrogen companies and research and development groups for the production, transport, and usage of hydrogen as a clean energy carrier.

Hydrogen - PowerPedia
A hydrogen economy is a vision of the future economy in which energy, for mobile applications (vehicles, aircraft) and electrical grid load balancing (daily peak demand reserve), is stored as hydrogen (H2).

Hydrogen - PESWiki
Index of hydrogen technologies, including hydrogen generation as well as hydrogen use as fuel.

HydroPowerCar
The goal is to create a car that will get 100 mpg. Using off the shelf materials with the use of hydrogen,solar,and kinetic energy. I believe this can be done on a HOD (hydrogen on demand).
