Inogen designs hybrid wind and solar based power generation systems, primary interest on the VAWT  - Vertical Axes Wind Turbines due to their low noise and lower wind speed generation. VAWT technology started from a few kW power ratings. Nowadays the power stations exceeds MW ranges.

Biomass power station is essential in management of waste and clean life cycle of world resources. Inogen develops pilot scale biomass unit using  gasification technology. The unit is under operation in one of the municipal place. Once the tests will use reach desired energy levels, industrial scale biomass gasification plants will be manufactured.
