OPEN 2012 Projects

United Technologies Research Center (UTRC) is using additive manufacturing techniques to develop an ultra-high-efficiency electric motor for automobiles. The process and design does not rely on rare earth materials and sidesteps any associated supply concerns. Additive manufacturing uses a laser to deposit copper and insulation, layer-by-layer, instead of winding wires. EV motors rely heavily on permanent magnets, which are expensive given the high concentrations of rare earth material required to deliver the performance required in today’s market.

University of North Dakota Energy & Environmental Research Center (UND-EERC) is developing an air-cooling alternative for power plants that helps maintain operating efficiency during electricity production with low environmental impact. The project addresses the shortcomings of conventional dry cooling, including high cost and degraded cooling performance during daytime temperature peaks. UND-EERC’s device would use an air-cooled adsorbent liquid that results in more efficient power production with no water consumption.

The University of Illinois, Urbana-Champaign (UIUC) is developing scalable grid modeling, monitoring, and analysis tools that would improve its resiliency to system failures as well as cyber attacks, which can significantly improve the reliability of grid operations. Power system operators today lack the ability to assess the grid’s reliability with respect to potential cyber failures and attacks.

The University of California, Santa Cruz (UC Santa Cruz) is developing an optical device that enables the use of concentrated solar energy at locations remote to the point of collection. Conventional solar concentration systems typically use line of sight optical components to concentrate solar energy onto a surface for direct conversion of light into electricity or heat. UC Santa Cruz’s innovative approach leverages unique thin-film materials, processes, and structures to build a device that will efficiently guide sunlight into an optical fiber for use away from the point of collection.

Silicon Power is developing a semiconducting device that switches high-power and high-voltage electricity using optical signals as triggers for the switches, instead of conventional signals carried through wires. A switch helps control electricity, converting it from one voltage or current to another. High-power systems generally require multiple switches to convert energy into electricity that can be transmitted through the grid. These multi-level switch configurations use many switches which may be costly and inefficient.

Pratt & Whitney Rocketdyne (PWR) is developing two distinct—but related—technologies that could revolutionize how we convert natural gas. First, PWR will work with Pennsylvania State University to create a high-efficiency gas turbine which uses supercritical fluids to cool the turbine blades. Allowing gas turbines to operate at higher temperatures can drive significant improvements in performance, particularly when coupled with the recapture of waste heat. This advancement could reduce the cost of electricity by roughly 60% and resulting in significantly lower greenhouse gas emissions.

Pacific Northwest National Laboratory (PNNL) is developing innovative high-performance-computing techniques that can assess unused power transmission capacity in real-time in order to better manage congestion in the power grid. This type of assessment is traditionally performed off-line every season or every year using only conservative, worst-case scenarios.

Palo Alto Research Center (PARC) is developing a new way to manufacture Li-Ion batteries that reduces manufacturing costs and improves overall battery performance. Traditionally, Li-Ion manufacturers make each layer of the battery separately and then integrate the layers together. PARC is working to manufacture a Li-ion battery by printing each layer simultaneously into an integrated battery, thereby streamlining the manufacturing process. Additionally, the battery structure includes narrow stripes inside the layers that increase the battery’s overall energy storage.

Massachusetts Institute of Technology (MIT) is developing a water treatment system to treat contaminated water from hydraulic fracking and seawater. There is a critical need for small to medium-sized, low-powered, low-cost water treatment technologies, particularly for regions lacking centralized water and energy infrastructure. Conventional water treatment methods, such as reverse osmosis, are not effective for most produced water clean up based on the high salt levels resulting from fracking.

Georgia Tech Research Corporation is developing a method to capture energy from wind vortices that form from a thin layer of solar-heated air along the ground. “Dust devils” are a random and intermittent example of this phenomenon in nature. Naturally, the sun heats the ground creating a thin air layer near the surface that is warmer than the air above. Since hot air rises, this layer of air will naturally want to rise. The Georgia Tech team will use a set of vanes to force the air to rotate as it rises, forming an anchored columnar vortex that draws in additional hot air to sustain itself.
