As consumers we are ever more connected these days through tablets, smartphones, smart watches, and smart glasses, while the abundance of apps has made our lives more convenient and interesting. However, the battery in these electronics barely lasts a day. SolidEnergy Systems’ Solid Polymer Ionic Liquid (SPiL) rechargeable lithium battery could potentially be the biggest breakthrough in battery technology since Sony introduced the first Li-ion battery in 1991.

The control of power flow in power systems is a major concern for utilities and system operators. But full power flow control has been prohibitively expensive, requiring large numbers of complicated and costly devices. As a result, power systems almost always operate sub-optimally at billions of dollars per year. A simple, magnetic-field-based valve-like device for power flow control, the Continuously Variable Series Reactor (CVSR), developed by Oak Ridge National Laboratory, SPX Transformer Solutions Inc. and the Univ. of Tennessee, has introduced substantial improvements.
Pacific Northwest National Laboratory’s Solar Thermochemical Advanced Reactor System (STARS) addresses a major criticism of solar energy, which, like wind power, can’t provide continuous output. Because of its design, STARS doesn’t require power plants to cease operations when the sun sets or clouds cover the sky.
The photovoltaic industry is particularly sensitive to cost, and while pushing the envelope on conversion efficiency is a priority, efforts to reduce manufacturing costs is also a priority. Toward this end, TetraSun Inc. and the National Renewable Energy Laboratory have developed TetraCell solar cells, which offer a bifacial, high-efficiency ($3.09 per Watt-peak) solution for photovoltaic applications.
Fuel cells are typically viewed as complex or expensive devices. However, Point Source Power and Lawrence Berkeley National Laboratory’s VOTO rugged metal-supported solid-oxide fuel cell is a simple, affordable technology that can operate directly on hydrocarbon fuels in the relatively uncontrolled environment of a cookstove.
The ClimateMaster Trilogy 40 Q-Mode water-to-air packaged geothermal heat pump unit, developed by ClimateMaster and Oak Ridge National Laboratory, is the first geothermal heat pump to exceed a certified cooling efficiency of 40 EER (energy-efficiency ratio) under the AHRI’s part load ground loop rating conditions.
Butanol is good drop-in fuel and surpasses ethanol with its higher heating value, its compatibility with current gasoline engines and its existing gasoline distribution infrastructure. However, for any biofuel to have a positive economic and environmental impact, production must be efficient, scalable and have a small carbon footprint. Industrial Technology Research Institute has developed a butanol production technology, called ButyFix, which is designed to meet the above requirements.
Numerous space probes have taken advantage of radioisotope thermoelectric generators (RTGs) powered by plutonium. However, the end of the Cold War has brought about a shortage of plutonium. In collaboration with NASA Glenn Research Center and National Security Technologies, Los Alamos National Laboratory has developed an alternative type of nuclear reactor, one that uses plentiful uranium as its fuel source.
Lawrence Berkeley National Laboratory’s Universal Smart Window (USW) Coating, constructed from an advance nanocrystal conducting oxide-base electrochromatic material embedded in a transition-metal-oxide matrix, is the first window coating to maximize thermal glare that enables dynamic control over heat-producing near-infrared radiation (NIR) and visible light from the sun independent of each other.
Lithium-ion battery separators prevent the anode and cathode layers from contacting each other, allowing cell potential to be maintained and safe operation of the battery. The SYMMETRIX HPX-F polymer-ceramic composite separator, developed by Porous Power Technologies and Oak Ridge National Laboratory, achieves this functionality while improving safety over conventional polyolefin membranes.
The worldwide market for portable electronic devices is quickly growing. These devices are predominantly battery-driven, and a challenge looms for maintaining, charging and disposing of these millions of batteries. Lawrence Berkeley National Laboratory’s Bacteriophage Power Generator offers a potential alternative.
Currently, electric grids have limited ability to store excess energy, so electricity must constantly be generated to perfectly match demand. Hence, power generation, transmission and distribution must accommodate the maximum demand of conditions and must include significant standby generation capacity. This adds capital expense, and forces power plants to idle or operate at non-efficient conditions. United Technologies Research Center has developed a flow-battery technology—called PureStorage—that provides affordable, safe, energy-efficient and readily deployable electrical energy storage.
Understanding and controlling temperature is necessary for the successful operation of battery packs in electric-drive vehicles (EDVs). Isothermal Battery Calorimeters (IBCs), developed by National Renewable Energy Laboratory and NETZSCH North America, are the only calorimeters that can accurately measure heat generated from batteries used in EDVs—with a baseline sensitivity of 10 mW and heat detection as low as 15 J—while being charged and/or discharged.
