Utility Hawaiian Electric has announced the start of operations of a pilot project featuring flywheel energy storage technology provided by Amber Kinetics. The project will test the technology’s capability of supporting the grid and allowing further integration of renewable generation.
Researchers in the U.S. have confirmed the existence of a novel state of the element manganese, first proposed in a journal dating from 1928, which could allow for the development of low-cost, high performance batteries for grid level and other energy storage applications.
Scientists led by Brown University have developed perovskite solar cells, which replace the toxic lead common to many of these material structures with titanium. The researchers say that with further optimization, the material could eventually be ideal for use as a tandem cell layer.
A team from the U.S. National Renewable Energy Laboratory (NREL) has developed a novel microscopic technique, which enables them to observe degradation in perovskite materials at the nano-scale and pinpoint key areas to improve the stability and durability of the material.
A report published by TÜV Rheinland, which was commissioned by tracker manufacturer Array Technologies, shows that centralized tracker systems such as those offered by Array Technologies offer an LCOE advantage over other, decentralized system architectures.
A team from the University of Massachusetts, Amherst (UMass) have developed a polymer based energy storage system, which releases energy on demand as heat. The scientists say that their system utilizes a polymer chain ‘organized like a string of Christmas lights’ and can achieve more than double the storage density of previous polymer based systems.
Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have created a solar cell using colloidal quantum dots, which achieved 13.4% conversion efficiency – a new world record for this emerging technology.
