Technology for tomorrow's transportations

We turn waste heat into hydrogen and build fuel cell components for cleaner and more efficient transport solutions.

World-leading fuel cell development

SRM has worked with fuel cell development for more than 30 years. With our experience we have now developed  a world-leading and unique method for hydrogen production from waste heat.

SRM waste heat to power is the cheapest continuous source of electricity for producing hydrogen and is a technology for tomorrows transportation solutions. Fuel cell systems for vehicles are currently the only known practical technology that can replace oil-based combustion engines and meet ever-stricter environmental requirements.

This is SRM Autorotor

SRM Autorotor develops and manufactures air systems for use in fuel cell applications.

The SRM Autorotor system advantages include:

  • High efficiencies
  • Reliable operation and control
  • Broad pressure and air flow ranges

SRM offers customized solutions in addition to well proven compressor solutions. The product line also include a convenient power recovery with the help of expander solutions.

What is a fuel cell?

Fuel cells have been developed as an alternative to the internal combustion engine in vehicles as well as to stationary converters of energy for production of electrical energy. The most common technology is based on the reaction of hydrogen and oxygen inside the fuel cell. Electrical energy is generated and the emissions from the fuel cell contain only air and water. The fuel cell technique can solve several of todays problems with traditional battery techniques, especially the possibility to enlarge the driving range.

A fuel cell system consists of a fuel cell stack (which in turn contains hundreds of fuel cells), a hydrogen tank and an air system. Fuel cells convert hydrogen and oxygen into electrical current that can be used to power an electrical motor.

Emissions from a fuel cell vehicle running on hydrogen consist of water only. The capacity of the fuel cell is enhanced when compressors are used to supply compressed air. The total efficiency of the fuel cell system is higher than the efficiency of a traditional internal combustion engine.

The challenge in development work for fuel cell systems is to improve performance and life-length of the air systems and develop a technology that saves materials, weight and fuel. With traditional hydrogen systems, the energy use is often a substantial cost. Innovative systems, like SRM’s, that use waste energy to produce hydrogen, is the key to a sustainable future.
