Researchers in Denmark have studied the technical and economic feasibility of biomethanation through large-scale PV power generation. They said that the intermittent PV-driven biomethanation process matches the efficiency of continuous processes after several days.

A new imaging system for contactless defect detection in roll-to-roll printed thin film solar cell manufacturing lines is available from InfinityPV, a Danish printed electronics equipment manufacturer. The so-called ultrafast laser beam induced current mapping system is suitable for manufacturers of perovskite, organic, kesterite, copper indicum gallium diselenide (CIGS) and amorphous silicon PV foils and can be retrofitted into existing roll-to-roll lines.

An international team of scientists has assessed different strategies for volume-based and fixed-amount subsidy auctions for large-scale wind and solar projects. They have found that higher subsidy levels in auctions lead to lower final prices.

The Japanese government has confirmed to pv magazine that it is launching a new support scheme for hydrogen in aviation, while Japanese investors continue to actively pursue participation in a green ammonia project in South Africa.

India and Saudi Arabia have agreed to develop electrical interconnections and low-carbon hydrogen, while Masdar has partnered with Boeing ion the sustainable aviation fuel (SAF) industry.

With utility scale solar installations accelerating, Philip Wolfe, founder of PV data consultancy Wiki-Solar, drills into the data to highlight some interesting variations in relative progress around the world.

A research group led by the Technical University of Denmark has analyzed how booster heat pumps may effectively improve the performance of ultra-low temperature district heating networks in colder climates and has found that the refrigerant change plays a crucial role. They also said that powering these heat pumps with renewables may also better integrate clean sources in energy systems.

Mexican researchers have revealed test results for offshore wind-based hydrogen production, while Turkey has started negotiating hydrogen facility partnerships with the United Arab Emirates.

Italy’s Prysmian has finalized the deployment of a high-voltage direct current (HVDC) submarine transmission line spanning 1,400 km, connecting Denmark to the United Kingdom.

Built by Danish researchers, the device also achieved a power conversion efficiency of 5.0%. They designed the cell with a soda-lime glass substrate, a tin oxide (FTO) layer, an electron transport layer made of titanium oxide (TiO2), a selenium absorber, a molybdenum oxide (MoOx) layer, and a gold (Au) metal contact.
