Hydrogen is the simplest element and most plentiful gas in the universe. Hydrogen never occurs by itself in nature. It combines with other elements such as oxygen and carbon.

But once it has been separated, hydrogen is the ultimate clean energy carrier. Hydrogen is considered the obvious alternative to hydrocarbon fuels. Hydrogen has many potential uses, is friendly to our environment, and is safe to manufacture.

Today, many technologies exist that can use hydrogen to power cars, trucks, and electrical plants.

A Hydrogen Powered World
This site is managed by The Clean Energy Educational Trust to promote the concept of a hydrogen powered world. Their aim is to raise general awareness of the possibility of changing the source of the world's energy supplies from fossil fuels and nuclear power to a pollution-free energy system based on hydrogen.

American Hydrogen Association
The goal of AHA is to stimulate interest and help establish the renewable hydrogen energy economy by the year 2010. To achieve this goal, the American Hydrogen Association is working in cooperation with organizations and industry, community, and schools to promote understanding of hydrogen technology, and help create a marketplace for pollution-free hydrogen energy.

Canadian Hydrogen Association
A non-profit membership association composed of universities, research organizations, industry and small business. Its objective is to promote the use and development of hydrogen energy, hydrogen energy systems and technologies and to develop the role of hydrogen energy for the purpose of improving the environment.

Cross Creek Initiative
The CCI is a a non-profit organization. Their mission is to champion the worldwide shift to maximum efficiency and planet-friendly energy.

European Hydrogen and Fuel Cell Technology Platform
The European Commission is facilitating the establishment of a European Hydrogen and Fuel Cell Technology Platform aimed at accelerating the development and deployment of these key technologies in Europe.

Fuel Cell Industry Report
Is the leading publication in its field. Each month manufacturers, integrators, suppliers and end users turn to Fuel Cell Industry Report to keep up with the rapid advances in fuel cell commercialization.

Fuel Cell Technology Showcase
The Society of Automotive Engineers (SAE International) is known globally as a leading source for automotive technology. SAE has developed the Fuel Cell Technology Showcase as a resource for the latest books, standards, articles, events and more with relation to fuel cell energy and fuel cell vehicles.

How the Hydrogen Economy Works
The world is moving toward what is broadly known as the hydrogen economy. We will soon being to see the shift away from the fossil fuel economy to a much cleaner hydrogen future.

Hydrogen Energy Center
A non-profit organization working toward a sustainable energy economy based on a renewable hydrogen program. Committed to advancing the transition to a renewable hydrogen energy economy through education, demonstration, and advocacy.

Hydrogen and Fuel Cell Glossary
U.S. Department of Energy glossary guide.

Hydrogen Now!
A non-profit organization based in Fort Collins, Colorado, U.S.A., committed to influencing and having a direct impact on the transition to a hydrogen economy. Hydrogen Now! reaches around the world; its advisors and board members worldwide comprise over 100 years of combined expertise in hydrogen energy.

International Association for Hydrogen Energy
The Association strives to advance the day when hydrogen power will become the principal means by which the world will achieve its long-sought goal of abundant clean energy.

National Fuel Cell Research Center
The NFCRC is principally focused on stationary power and its role as a Distributed Generation technology. While efforts are underway on the components of fuel cell systems, a great deal of effort is focused on the development, integration, deployment and connectivity of fuel cell systems.

National Hydrogen Association
The NHA serves as a catalyst for information exchange and cooperative projects and provides the setting for mutual support among industry, government, and research/academic organizations.

Schatz Energy Research Center
An animation showing the process that goes on inside an individual fuel cell. Essential information about education on alternative, renewable energy sources.

UK Hydrogen Energy Network, The
(H2NET) was established in April 2000 as a joint collaboration between UK industry and academia interested in the development of hydrogen as an energy vector. Its principal aim is to promote research and discussion on issues connected with the development of the hydrogen energy economy. The formation of the Network was prompted by wider international developments in the technologies underpinning a hydrogen energy economy.

U.S. Fuel Cell Council
The U.S. Fuel Cell Council is an industry association dedicated to fostering the commercialization of fuel cells in the United States. Their members include the world's leading fuel cell developers, manufacturers, suppliers and customers.
