Technology and R&D

ERM says it has launched offshore trials to test its Dolphyn Hydrogen process, while Southern California Gas (SoCalGas) and Evoloh have completed a joint research project on electrolyzer manufacturing process and anion exchange membrane (AEM) electrolyzer tech.

At SNEC 2024 in Shanghai, pv magazine spoke with Puzant Baliozian, lead consultant of sector group photovoltaic equipment for Germany’s Machinery and Equipment Manufacturers Association (VDMA). He says tunnel oxide passivated contact (TOPCon) technology will dominate the solar market in the next 10 years and expects module manufacturers will compete to develop more creative product designs. He also believes that copper metallization will gain market share in heterojunction (HJT) module production in the next years. “In the upcoming decade, we will have less than mg/W of silver being used for both TOPCon and HJT technologies,” he stated.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that, while in June Western Europe experienced below-average irradiance, Eastern Europe and the Balkans in particular saw a notable increase, resulting from persistent and static weather patterns.

French company HDF Energy has equipped its new polymer electrolyte membrane (PEM) hydrogen fuel-cell production plant with a 500 kW solar project, by adjusting the PV modules and inverters to fit the sawtooth roof design.

An Australian-made, 10 kW renewable hydrogen generator has been installed 120 km east of Melbourne, as part of a pilot project to provide backup to telecom towers disabled by outages.

Researchers have simulated the operation of seven renewable energy communities in the Port of Naples and found them to offer lower life cycle costs. Using varying capacities of solar and wave energy, they were able to optimize the system to a 90% self-consumption rate. They also offered a scheme for the management of a port energy community.

Researchers in China have built for the first time an inverted perovskite solar cell relying on a high-entropy hybrid perovskite material. The result is a device with an improved open-circuit voltage and fill factor, due to reduced non-radiative recombinations and optimized interface.

Researchers in Italy have developed a low temperature a blanket-cover encapsulation technique that reportedly improves the stability of perovskite PV devices. They said the new technique reduces thermomechanical stresses caused by both the encapsulation process and the temperature gradients occurring during accelerated ageing stresses.

Australian zinc bromide flow battery specialist Redflow has struck a partnership with Queensland state-owned generation company Stanwell to work together on the development of a non-lithium long-duration battery energy storage solution for use in a 400 MWh project. Meanwhile, Toronto long duration energy storage specialist e-Zinc has secured $31 million which will go towards developement and completion of its pilot manufacturing facility in Mississauga, Ontario.

Researchers in Italy outlined a new model for estimating hydrogen production cost as a function of the plant’s component sizes. They tested both PV, wind, and hybrid production of hydrogen to determine the optimal size ratio for the 2030-2050 period. They also found that PV-powered hydrogen may currently achieve a levelized cost of hydrogen of €5.11/kg in Italy, with a PV ratio of 2.2.
