• Power Tree Corp., Boca Raton, Fla., recently announced the commencement of construction of its fourth-generation electricity storage device. The company’s new device is designed to cost-effectively and efficiently store up to 30GW of electricity and discharge continuous megawatt power for hours.

  • Ascent Solar Technologies, Thornton, Colo., has achieved its initial target module efficiency goal of 10% for its flexible copper, indium, gallium, selenide (CIGS) monolithically integrated modules. The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has independently verified that the modules measured as high as 10.4% in conversion efficiency.

  • Ice Energy, Santa Clara, Calif., provider of distributed energy storage and smart grid solutions for optimizing energy system efficiency, has teamed with Data Aire, Orange, Calif.-based provider of computer room air-conditioning systems, to offer the industry's first cost-effective energy storage solution specifically developed to address peak cooling loads in data and telecom centers. The companies have completed compatibility testing of Ice Energy's Ice Bear distributed energy storage system with Data Aire's Data Temp cooling systems to deliver an integrated hybrid cooling product that enables data and telecom centers to slash on-peak electricity demand, better manage energy costs, and reduce their building's environmental footprint.

  • TÜV SÜD America, Peabody, Mass., has announced a cooperation agreement with Renewable Energy Test Center (RETC), Fremont, Calif.-based engineering services and test provider. Through this cooperation, RETC will provide TÜV SÜD a global partner for testing and certification for photovoltaics (PV) and renewable-energy products, including third-party outdoor performance, and reliability testing.

  • Penta Technologies, Milwaukee, provider of enterprise software for the engineering and construction industries, recently announced that ITAC Engineers and Constructors has selected Penta as their new engineering and construction management software. “One of the most important considerations in our system search was that we would no longer need to build and maintain custom systems outside the business financial system,” says Jon Loftis, president of ITAC Engineers and Constructors. “We needed software that could manage engineering, design-build, and self-perform construction work, all in one database.”
