Delphi Automotive Systems is developing power converters that are smaller and more energy efficient, reliable, and cost-effective than current power converters. Power converters rely on power transistors which act like a very precisely controlled on-off switch, controlling the electrical energy flowing through an electrical circuit. Most power transistors today use silicon (Si) semiconductors. However, Delphi is using semiconductors made with a thin layer of gallium-nitride (GaN) applied on top of the more conventional Si material. The GaN layer increases the energy efficiency of the power…

Ford is developing an on-board adsorbed natural gas tank system with a high-surface-area framework material that would increase the energy density of compressed natural gas at low pressures. Traditional natural gas tanks attempt to compensate for low-energy-density and limited driving range by storing compressed gas at high pressures, requiring expensive pressure vessels. Ford and their project partners will optimize advanced porous material within a system to reduce the pressure of on-board tanks while delivering the…

Form Energy

Form Energy will develop a long-duration energy storage system that takes advantage of the low cost and high abundance of sulfur in a water-based solution. Previous MIT research demonstrated that aqueous sulfur flow batteries represent the lowest chemical cost among rechargeable batteries. However, these systems have relatively low efficiency. Conversely, numerous rechargeable battery chemistries with higher efficiency have high chemical costs. The solution requires low chemical cost, high efficiency, and streamlined architecture. The team will pursue several competing strategies and…
