Fuel cells produce electricity and heat electrochemically by combining oxygen from the air with a fuel, preferably hydrogen, from methanol, natural gas, or petroleum. Reformers are often used in conjunction with fuel cells

Alternative power generators produce electricity from renewable energy sources, such as wind, flowing water, solar energy and biomass, which create less environmental damage and pollution than fossil fuels

Battery and fuel cell test equipment consists of specialized test stations, stands or systems, monitors and component modules for performance or endurance testing. 

Load cells are transducers for force and load measurement, often with mounting packaging.  They are widely used in testing, instrumentation, and as components in larger devices such as scales

Specialty fibers, fabrics and textiles are based upon a unique composition, weave, or technology, and are designed for specialized applications.

Potentiostats and galvanostats are electrochemical instruments used in electrochemistry, battery and fuel cell testing, corrosion control, voltammetry, biomedical research, surface imaging, and related applications

Energy product testing services test, evaluate, and analyze the safety, efficiency and performance of energy storage, power generation, and transmission systems that use conventional, renewable or alternative energy.

Rechargeable batteries or secondary batteries contain active materials that can be regenerated by charging. When the energy produced by rechargeable batteries drops below optimum efficiency, secondary batteries may be recharged in a couple of ways, depending upon their construction. 

Cogeneration equipment produces power and thermal energy from a common fuel source, generally one that is considered to be a waste product from another process

NDT supplies and accessories are components, ancillary equipment, standards, and consumable materials used in non-destructive testing (NDT).

Specialty polymers and resins are proprietary polymers, resins, monomers and intermediates. This category includes plastics and elastomers that are based on proprietary curing technologies or chemistries, or that are designed for specialized applications.

Reserve batteries separate the electrolyte from the rest of the battery so that the electrolyte remains inert.

Analytical laboratory services detect, classify and/or assay chemical, material, biological, geological and environmental samples.

Plastics and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms.

Foams and foam materials are industrial products made from low density elastomers, plastics, and other materials with various structures and porosities.
