SwRI will be exhibiting at the ARPA-E Energy Innovation Summit, Booth No. 611 and 639.
Booth No. 611 - Brittany Tom, Mechanical Engineering
Grid-scale Electricity Storage at Lowest Possible Cost: Enabled by Pumped Heat Electricity Storage
SwRI is developing an advanced pumped heat electricity storage system based on a novel thermodynamic cycle to store energy in hot and cold fluids. This large energy storage system will help integrate renewables with the electric grid. This technology relies on system simplification, high round-trip conversion efficiencies, and low plant costs to surpass existing state-of-the-art energy storage technologies. At full scale the technology would provide more than 10 hours of electricity at rated power. SwRI will build a small kW-scale electric demonstrator to validate this novel technology

Model Predictive Control for Energy-Efficient Maneuvering of Connected Autonomous Vehicles
SwRI’s automotive engineers are advancing connected and automated hybrid vehicle technologies with the goal of improving fuel economy by more than 20 percent. Working with University of Michigan and Toyota Motor Corp., SwRI has developed control algorithms to optimize a hybrid vehicle’s route, speed profile and power flows. This real-time control is more efficient than dynamic cruise control and improves the power-split between battery and liquid fuel based on the preview of the road ahead, producing fuel savings in excess of 10 percent and in certain scenarios up to 20 percent. Routes are optimized for both energy savings and arrival times. The technology uses existing applications such as Google Maps to preview the route ahead, including highway grade, stop signs, lights and traffic volume to choose the most energy efficient route. Integrated vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technology will help achieve near optimal fuel economy. The project is funded by the Advanced Research Projects Agency-Energy (ARPA-E) NEXTCAR program, under Award Number DE-AR0000837.
