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.

A group of researchers in Denmark has investigated how Carnot batteries may be used to store renewable energy in their home country and have found that these devices may provide a significant contribution only under a certain cost threshold.

As the US and British government press ahead with their hydrogen support projects, a team from Korea and the US has developed an iridium nanostructure catalyst, which decreased the amount of the chemical element. Meanwhile, hydrogen projects are proceeding in West Virginia, Denmark, Finland, and Japan.

A German research team says that demand for iridium, lanthanum and nickel could weigh on the growth of the global hydrogen-powered aviation market.

Utilities increasingly recognize heat pumps as a critical technology for heat decarbonization. They are deploying multi-megawatt systems in different parts of Europe to simultaneously serve multiple users and offer new avenues for the decarbonization of buildings.

Researchers in Denmark have analyzed the potential of PV systems and their influence on the underlying farmland in three different agrivoltaic projects, including vertical bifacial optimal tilted, horizontal single-axis tracking, and vertical bifacial setups. They also calculated the potential for agrivoltaic in every region in the European Union and found that the eligible areas are unevenly distributed.

German engineering conglomerate thyssenkrupp has listed shares of its hydrogen business, thyssenkrupp nucera, on the Frankfurt Stock Exchange (Prime Standard).
