100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

Proton OnSite designs, develops, and manufactures proton exchange membrane (PEM) electrochemical systems to make hydrogen from water for customers in the United States and internationally. Its products include onsite hydrogen generation systems for laboratories, silicon semiconductor and metal organic chemical vapor deposition processes, materials processing, and meteorological applications; and PEM electrolysis systems for centralized fueling and neighborhood fueling. The company also offers regenerative fuel cell systems for traditional lead acid batteries and diesel generator sets. It serves military, aerospace, fueling, and renewable energy industries. The company was formerly known as Proton Energy Systems, Inc. and changed its name to Proton OnSite in April 2011.

Proton OnSite was formally accepted as a member of EHA as of 21 June 2012
