Technology and R&D

The Agua+S project under development in the Spanish region of Andalucia is aimed at combining a desalination plant, a pumping station network, and an onshore, floating photovoltaic plant in a single project design. According to its developers this is the first time that these three facilities have been combined together in a fully reproducible design that could be replicated in any river basin that has a reservoir and is close to the coast, to produce fresh water for both irrigation and human consumption.

Researchers from Qatar and South Korea have studied the potential of solar cells based on 2D MXenes materials. They said that titanium carbide MXene (Ti3C2Tx) is the most promising material in the MXene family for PV applications.

Panasonic has unveiled a new product in Japan with a PV-based charging function that uses a heat pump and hot water storage unit to save energy by maintaining bathwater temperatures at constant levels.

OnSight Technology has developed a tele-operated vehicle to clean solar arrays. It is equipped with a radiometric thermal imaging camera and an optical zoom camera backed by artificial intelligence. It has a range of 12 hours and a speed of 1.6 km per hour.

A Swedish research group has developed a device combining CIGS thin-film solar modules and an alkaline electrolyzer based on a trimetallic cathodic catalyst made of nickel, molybdenum, and vanadium (NiMoV) and an anode made of nickel oxide (NiO). The electrolyzer achieved an average solar-to-hydrogen (STH) efficiency of 8.5% for stable operations during 100 hours.

Called GC PowerNest, the battery has a storage capacity of 5kWh and a voltage of 51.2V. It is scalable in an eight-stack configuration, thus reaching a capacity of up to 40kWh.

UL and the US National Renewable Energy Laboratory have released a report on cybersecurity certification recommendations and are actively developing new requirements to create cybersecurity certification standards.

Conceived by researchers in Estonia, the device is claimed to be compatible with both crystalline silicon and thin-film BIPV panels and to manage, easily, different voltage levels. It can be applied either in solar facades or BIPV rooftop arrays.

Developed by a Dutch consortium, the Hide and Shine Floating Solar (HAS FPV) technology is claimed to be extremely resistant to storms and harsh weather conditions. The modules can be submerged totally or partially and, in case of a severe storm, they can be submerged up to two meters below the surface.
