In recent years, Longi has turned its attention to green hydrogen. Li Zhenguo, company founder and CEO, recently spoke to pv magazine about its strategic shift and how he believes that coupling this technology with solar PV will be the key to achieving carbon neutrality.

Bearing witness during battery energy storage system manufacturing can reveal potential failure points and is crucial given the industry’s relative immaturity, argues Frédéric Dross, the vice-president of strategic development for quality assurance provider STS. And much can be learned from the early days of solar.

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.

Bromine-based flow batteries have the potential for high energy density in renewable energy storage. Their commercial adoption, however, remains challenging due to the cathode materials used for their construction. New research from China seeks to shed light on how to overcome these hurdles.

PV ICE uses the latest data from the solar industry to model the flow of PV materials over the next several decades, helping to predict the effects of different market trends, technological developments, and government policies.

For some developers of ground-mounted PV, bifacial modules are already the default technology. The slight cost increase is often outweighed by an increase in energy yield. And yet “agreeing” on the right energy yield of a PV plant has always been the most heated debate between developers, investors, lenders, and technical advisers. Everoze partner Christophe Campistron looks at both sides.

New research has categorised all existing fault detection and localisation strategies for grid-connected PV inverters. The overview also provides a classification of various component failure modes and their potential causes in a tabular form.

Energy Dome’s emission-free energy storage method uses carbon dioxide in a closed loop charge/discharge cycle that can store and dispatch renewable energy onto the grid over periods from four to 24 hours.

The global battery energy storage market will grow to US$10.84 billion (AU$14.54 billion) in 2026, with around two-thirds of the demand concentrated in the Asia Pacific region.

Solar data company Solargis has released 10-year solar performance maps showing Australia’s massive variations in irradiance and the impacts of extreme weather patterns and events.
