Cash flow analysis shows adiabatic compressed air storage is viable for 10–100 h applications
Scientists in the United Kingdom have compiled a new database of adiabatic compressed air energy storage projects. Using this data, they were able to determine the experience rate and identify the conditions under which the technology would be economically viable. According to their findings, costs have declined at a 15% learning rate since 2013.
Chinese scientists build 18%-efficient organic solar cells with enhanced stability
Chinese researchers have demonstrated organic solar cells with novel encapsulation and a protective interfacial layer for enhanced stability and efficiency. The best performing cell based on the new approach retained 94% of its initial power conversion efficiency after standards-based damp heat testing for 1,032 hours damp heat and across 200 thermal cycles.
