OPEN 2015 Projects

Tibbar Technologies will develop plasma-based AC to DC converters for a variety of applications, including DC power for commercial buildings and for High Voltage Direct Current (HVDC) electrical transmission. A plasma is created when a gas absorbs enough energy to separate the electrons from the nuclei, making it susceptible to electric and magnetic fields. In this project the team will develop a converter based principally on a single plasma component, rather than a system of capacitors and semiconductor switches.

The team led by the University of New Mexico will develop a modular electrochemical process for a power-to-fuel system that can synthesize ammonia directly from nitrogen and water. The proposed synthesis approach will combine chemical and electrochemical steps to facilitate the high-energy step of breaking the nitrogen-nitrogen bond, with projected conversion efficiencies above 70%.

Colorado State University (CSU) and its partners are developing an inexpensive, polymer-based, energy-saving material that can be applied to windows as a retrofit. The team will develop a coating consisting of polymers that can rapidly self-assemble into orderly layers that will reflect infrared wavelengths but pass visible light. As such, the coating will help reduce building cooling requirements and energy use without darkening the room.

The Ocean Renewable Power Company (ORPC) will develop an innovative, self-deploying MHK power system, which will reduce the operating costs and improve the efficiency of MHK systems by up to 50%. ORPC’s system is based on pitch control of the blades of a cross-flow turbine, in which the tidal flow passes across the turbine blades rather than in a radial fashion. This system will allow the turbine to self-propel itself to the deployment location, and lower itself to the sea floor remotely.

The team led by Achates Power will develop an internal combustion engine that combines two promising engine technologies: an opposed-piston (OP) engine configuration and gasoline compression ignition (GCI). Compression ignition OP engines are inherently more efficient than existing spark-ignited 4-stroke engines (potentially up to 50% higher thermal efficiency using gasoline) while providing comparable power and torque, and showing the potential to meet future tailpipe emissions standards.

The University of Michigan team will develop a compact micro-hybrid configuration that pairs an Electrically Assisted Variable Speed (EAVS) supercharger with an exhaust expander Waste Energy Recovery (WER) system. Together, the EAVS and WER can nearly eliminate the slow air-path dynamics associated with turbocharge inertia and high exhaust gas recirculation (EGR).

The team led by Starfire Energy will develop a modular, small-scale, HB-type process for ammonia synthesis. The team’s innovative approach is less energy-intensive and more economical than conventional, large-scale HB because a novel electroactive catalyst allows operation at lower temperatures and pressures. Their approach combines a high-activity precious metal catalyst and an electroactive catalyst support to form ammonia molecules, while operating at moderate pressures and using localized high-temperature reaction zones.

The team led by Pacific Northwest National Laboratory (PNNL) will develop a High-Performance Power-Grid Optimization (HIPPO) technology to reduce grid resource scheduling times to within a fraction of current speeds, which can lead to more flexible and reliable real-time operation. The team will leverage advances in optimization algorithms and deploy high-performance computing technologies to significantly improve the performance of grid scheduling.

The team led by Oregon State University (OSU) is developing a novel gas-to-liquid (GTL) technology that utilizes a “corona discharge” plasma to convert methane to higher value chemicals, such as ethylene or liquid fuels. A corona discharge is formed when a high voltage is applied across a gap with a shaped electrode that concentrates the electric field at a tip. At sufficiently high voltage, an electrical discharge (characterized by a faint glow - a corona) is formed, and ionizes the surrounding gas molecules, i.e. split them into positive ions and free electrons.

University of Tennessee (UT), along with their partners, will develop a new type of microgrid design, along with its corresponding controller. Like most other microgrids, it will have solar PV-based distributed generation and be capable of grid-connected or disconnected (islanded) operations. Unlike other microgrids, this design will incorporate smart grid capabilities including intelligent switches and high-speed communication links. The included controller will accommodate and utilize these smart grid features for enhanced performance and reduced costs.
