U.S. Dept. of Energy Supports New Renewable Energy Storage System

The two bottlenecks inhibiting further use of renewable energy systems are cost and the fact that the sun doesn’t always shine or the wind blow-in one word, storage. While mass production of components such as solar photovoltaic cells means that their price has been dropping, the issue of storing and releasing electricity generated by renewable sources during their down times has led engineers worldwide to tackle the problem.

Large-scale, low-cost energy storage is needed to improve the reliability, resiliency, and efficiency of next-generation power grids. Energy storage can reduce power fluctuations, enhance system flexibility, and enable the storage and dispatch of electricity generated by variable renewable energy sources such as wind, solar, and water power.

Now one technology seems sufficiently promising that it is receiving funding from the U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability Energy Storage Program.

What is this promising new technology?

Isothermal compressed air energy storage (ICAES) refers to storage of compressed air at a constant temperature, which is a key element in the improved energy efficiency of the system.

SustainX has completed construction of its first utility scale ICAES system. It was hooked up to the grid earlier this month and it’s now in the process of revving up to speed. The DOE’s Office of Electricity Delivery and Energy Reliability’s Energy Storage Program underwrote $5,396,023 of the system’s cost.

Kipp & Zonen - DustIQ the novel soiling monitoring solution for solar panels

Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there's a new, simple and very cost-effective alternative. Based on Kipp & Zonen's unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated.
