In February 2014, REL featured at ARPA-e Energy Innovation Summit in Washington DC.
REL is developing a low-cost, conformable natural gas tank for light-duty vehicles that contains an internal structural cellular core. Traditional natural gas storage tanks are cylindrical and rigid. REL is exploring various materials that could be used to design a gas tank's internal structure that could allow the tank to be any shape. The REL team is exploring various methods of manufacturing the interconnected core structure and the tank skin to identify which combination best meets their target pressure-containment objectives. REL's conformable internal core would enable higher storage capacity than current carbon fiber-based tanks at 70% less cost. REL is developing small-scale prototypes that meet their durability, safety, and cost goals before scaling up to a full-sized prototype.
