NASA scientists have partially cleaned up the solar modules of the Insight lander operating on Mars, by using grain sands collected nearby and trickling them on the panels during the windiest time of the dayNASA scientists have partially cleaned up the solar modules of the Insight lander operating on Mars, by using grain sands collected nearby and trickling them on the panels during the windiest time of the day
Lithium saturation to make old batteries newScientists investigating the aging mechanisms affecting today’s lithium-ion batteries observed that the loss of lithium over time is one of the main causes of performance loss. With this in mind, they developed and tested a “relithiation” process that promises to eliminate much of the cost and complexity from recycling battery components and materials.
Submarine cable to connect 10.5 GW wind-solar complex in Morocco to the UK gridUK-based Xlinks is planning to build 10.5 GW of wind and solar in Morocco and sell the power generated by the huge plant in the UK. This should be made possible by a 3,800 km high voltage direct current (HVDC) transmission line that would be connected to locations in Wales and Devon. The company's CEO, Simon Morrish, spoke with pv magazine about the ambitious project, and on how it should become feasible.
Solar and silver price hikesThe PV industry has experienced several rounds of price increases since the second half of 2020, from polysilicon to materials such as PV glass and films. Between July 2020 and February 2021, prices quoted for 3.2 mm and 2 mm glass surged by more than 60% per square meter. Prices for EVA and POE encapsulant films skyrocketed by more than 40% and 10%, respectively. Prices for silver paste also rose 7%, and have since remained stubbornly high. PV InfoLink Chief Analyst Corrine Lin examines the impact of silver’s recent price turbulence on PV cell manufacturing.1
Solar may cover 75% of global electricity demand by 2050A new study from the Lappeenranta University of Technology predicts solar may even achieve a 69% share for total primary energy supply by the end of the first half of the century. In terms of price, solar PV is expected to achieve a capex of €246/kW-installed for utility scale projects, and of €537/kW for residential arrays by 2050. The levelized cost of energy (LCOE), however, is expected to remain constant over the next three decades, as the energy transition will also be implemented with storage technologies, increased flexibility and the production of synthetic fuels.
Australian scientists achieve breakthrough with renewably powered carbon captureAustralian scientists have achieved a new breakthrough in carbon capture and storage. Their novel electrochemical process can store carbon dioxide in water with the power of solar or wind, while also producing by-products such as green hydrogen and calcium carbonate – perhaps the key to decarbonizing the cement industry.1
Major milestone for world’s biggest solar projectThe world’s biggest solar+storage project is a step closer to realization, as the government of Australia’s Northern Territory and Singapore-based Sun Cable have signed a deal to advance the development of the Australia-ASEAN Power Link.
Solar-powered hydrogen for Masdar CityMasdar is launching a pilot green hydrogen project in the United Arab Emirates. In a recent conversation with pv magazine, two company officials described the project and explained how the hydrogen will be used for road transport, aviation and shipping in Masdar City.
The weekend read: The recent evolution of solar PV energy costsForecasts for the levelized cost of electricity (LCOE) of solar PV were hotly contested over the past decade, with one trend predominating: All but the most optimistic outlooks were wrong. pv magazine has gathered data to showcase the recent evolution of solar PV energy costs, and the results are stark. Within just a few years, initial projections become outdated, which means that forecasts of solar PV prices are more art than science.1
Power-to-X may cover 28% of global energy demand by 2050The so-called powerfuels are primarily required for sectors that are difficult to electrify, such as aviation and shipping, as well as for the processing of raw materials. This is shown by a new study by Finland's LUT University and the German Energy Agency.1
The world has 53 million hectares of abandoned cropland suitable for PV deploymentResearchers in Norway have mapped all cropland areas that were abandoned between 1992 and 2015 and found that the vast majority is suitable for PV and bioenergy deployment. Around 30% is located in Asia, followed by the Americas, with a 28% share, and Africa, with a percentage of 22%. Europe and Oceania had shares of 20% and 5%, respectively.1
The weekend read: Something truly newYou can try to succeed by making a better version of your competitors’ product, or you can try to do something completely new. NexWafe has chosen the second path. It is developing plans to manufacture wafers for high-efficiency solar cells in Bitterfeld, Germany, that are produced more sustainably and at lower cost than any other products available today.1
