Founded by a Indiana University professor of electrical and computer engineering in the School of Engineering and Technology and director of the Richard G. Lugar Center for Renewable Energy, Green Fortress seeks to refine its patented methods of storing hydrogen fuel in a solid state that could potentially lead to energy storage that is low in cost and high in round-trip efficiency. The patented technology behind the hydrogen storage also forms the foundation for the synthesis of biofuels, providing a pipeline of innovation in renewable energy. The firm reports discussions are ongoing with vehicle manufacturers producing fuel-cell vehicles.
