Virtual Special Issue: Hydrogen and Fuel Cells

Since its inception, Clean Energy has been encouraging authors to publish articles in support of urgently needed solutions to global climate change, especially in the fields of hydrogen and fuel cells.  

Hydrogen is a unique energy carrier, as it can be produced from various energy sources such as wind, fossil fuels and biomass and, when it is combusted, it emits no CO₂ emissions. Fuel cells are an important part of the hydrogen economy. Fuel cells for both transportation and stationary power applications can operate on hydrogen, as well as fuels like methanol, to produce power with no CO₂ emissions (if, for example, methanol is produced from CO₂ or hydrogen is produced from electrolysis using renewable energy).

The articles in this virtual issue have been selected by the Editors of Clean Energy to provide a broad view of current research in the areas of hydrogen and fuel cells. Concepts for transitioning to a hydrogen economy are presented in several articles. Important details for integrating hydrogen into the existing energy distribution system are presented, for example mixing hydrogen with natural gas. Producing hydrogen from renewable sources such as wind and solar energy or biomass is of critical importance. Finally, new concepts and new technologies are required in the area of fuel cells in order to realize the hydrogen economy in the future.
