Hydrogen and Fuel Cell Benefits

Hydrogen and fuel cell technologies provide cost effective and environmentally friendly solutions to improving our energy needs. Benefits include:

Energy Storage

Hydrogen is an energy storage medium. Energy, stored as hydrogen in the form of a gas or a liquid will never dissipate until it is used, making it a good application for emergency generators and other mission critical energy applications. Compare that to other energy storage types like batteries and capacitors which lose the energy stored in them over time and need to be periodically recharged even without use.

Energy Efficiency

Currently most internal combustion engines operate with an efficiency around 25% and power plants achieving about a 35% efficiency; however, a stationary fuel cell when used in a combined heat and power system can have an efficiency level of greater than 85%.

Environmental Impact

When hydrogen is used to power a fuel cell, the only byproducts are water and heat—no pollutants or greenhouse gases are produced. Even when fossil fuels are used to power a fuel cell the emissions are significantly reduced when compared with conventional energy generation technologies.

Domestic Energy Supply

With hydrogen generation sources ranging from solar arrays to nuclear power, the U.S. has the ability to create sustainable energy in an efficient and cost effective manner, while reducing our dependence on foreign oil and other fossil fuels.


Hydrogen fuel cells are cleaner and more efficient than traditional combustion-based engines and power plants. Hydrogen and fuel cells can also be used in mobile applications to power vehicles and mobile power packs.

The benefits of fuel cells are:

  • Reduced greenhouse gas emissions
  • High Reliability
  • Flexibility in installation and operation
  • Development of renewable energy resources
  • Reduced demand for foreign oil
  • Improved environmental quality
