Hydrogen market to surpass LNG by 2030, says Deloitte

Deloitte says it expects steady hydrogen market growth, with annual revenue projected to hit $1.4 trillion by 2050, while Denmark and the Netherlands have started discussing hydrogen collaboration with the governments of Namibia, South Africa, and Morocco.

Spotlight on TOPCon: PI Berlin shares concerns about degradation

Asier Ukar, the director of PI Berlin Spain, discusses the importance of addressing the risks associated with tunnel oxide passivated contact (TOPCon) tech early on, even though it outperforms (passivated emitter rear contact (PERC) when considering standard and tangible indicators.

VIT researchers study the impact of soling on solar modules

Scientists from the Vellore Institute of Technology in India carried out a comprehensive study into the impacts of soiling on PV modules – measuring the amount of performance loss caused by different types of dust and bird droppings, and for modules installed at various tilt angles, in the hot-dry climate of Vellore in southern India. Their findings could allow developers to better take into account and mitigate the effects of soiling during site selection and system design.
