A group of biologists in the United States working with a bacteria discovered a mechanism that could be used to convert electricity into biofuels or other useful substances. With better understanding of the genetics, the group says the mechanism could rival hydrogen for the storage of renewable energy.
The annual EU PVSEC conference started this morning, and the opening session saw renowned PV reliability expert Ulrike Jahn win the Becquerel Prize for her contribution to the development of PV technology.
This summer, IHS Markit published its annual global ranking of EPC providers that build in-house developed and third-party PV projects, based on last year’s installations. 2020 was a year of many contradictions, with lockdowns and increasing component prices taking their toll on many of the companies, both large and small. At the same time, EPC providers with their main share of business in mainland China and the United States had a remarkable year.
Moreover, two big Russian corporations have unveiled plans to produce hydrogen and Portuguese utility EDP said it wants to set up a a pilot project for a green hydrogen plant in Brazil.
Scientists in Switzerland found that perovskites can be used to detect thermal neutrons emitted by radioactive devices. Taking advantage of several properties that also make the materials attractive for solar cell applications, the group was able to fabricate a novel device that could have various practical applications, including in energy generation.
Scientists in the UK have explained the mechanism behind chlorine used to boost the efficiency of cadmium telluride thin-film solar cells. With new understanding of the chemical processes at work in the manufacturing process, the group hopes to be able to push for cell efficiencies beyond 25%.
Scientists in the United States used machine learning to analyze maintenance reports, performance data and weather records from more than 800 solar farms located across the country. The analysis allowed them to determine which weather conditions have the biggest impact on PV generation, and to suggest the most effective ways to boost the resilience of PV installations to extreme weather events.
Norwegian consultancy DNV today published the latest of its annual surveys of the state of the energy transition and lamented the fact so very little has been achieved during the last five years. We are forging ahead into a world that will be 2.3C hotter this century, predicts the report.
H2 Energy Europe is building a power-to-gas project in Denmark and Everfuel wants to put hydrogen refueling stations in Sweden. Chinese energy giant Sinopec said it wants to invest massively in hydrogen and the Australian Energy Market Operator (AEMO) has said hydrogen will be the main driver for “very quick” growth in electricity demand.
Scientists in the U.S. discovered a promising new battery chemistry based on chlorine and table salt. Batteries based on this chemistry can achieve at least six times the energy density of today’s lithium-ion batteries, according to the group that created it. The prototype battery could already be suitable for small devices such as hearing aids, and with further work could be scaled up to larger applications.
