Technology and R&D

Scientists have investigated how utility-scale solar may be used to power multistage flashing-brine recirculation (MSF-BR) water desalination plants in Aqaba, Jordan. They found the facility would be sufficient to provide the entire city with drinking water. The proposed system configuration comprises a 30 MW solar plant and a standar MSF-BR unit.

Germany’s Sunfarming is testing the new project design in cooperation with research centers Jülich and the Fraunhofer ISE.

Scientists in the United States developed a lithium-sulfur battery using a commercially available carbonate electrolyte, that retained more than 80% of its initial capacity after 4000 cycles. The group used a vapor deposition process which unexpectedly produced a form of sulfur that did not react with the electrolyte, overcoming one of the key challenges for this battery chemistry.

Researchers at the Indian Institute of Technology Delhi have developed solar towers that can be moved from one place to another and can generate 20-30% more power while requiring only 50-60% space compared to conventional mounting setups.

Consisting of a two-dimensional (2D) array of rings and pillars, the structure can improve the short-circuit current of a thin-film crystalline solar cell by over 50%, its creators say. The subwavelength AR structures are robust to certain degrees of fabrication errors, they add.

In new studies led by researchers from the National Renewable Energy Laboratory, the US Department of Energy pursues an energy cost goal of $0.05 per kilowatt-hour.

Ashutosh Verma, the founder of solar appliance manufacturer Exalta India, says that the key to expanding the uptake of solar products in rural parts of India lies in improving access to finance.

Researchers in Italy are combining PV with latent heat thermal storage (LHTM) and other renewable energy sources to maximize clean energy consumption in buildings. The 47kW PV array and LHTM system work independently, but the scientists said that a heat pump could be used to link them.

Soluna’s new generator can be combined in a two-unit system to reach a capacity of 2.5kWh. It features built-in 120V(AC) output, continuous AC output power of 1,200W, and peak output of up to 2,400W.

Through a conventional coloring technique for crystalline solar modules, scientists in Germany were able to manufacture a colorized small perovskite solar module in white marble optic displays that maintains up to 88.5% of the efficiency it had before coloring. The device was built with five cells interconnected in series and has a total area of 9cm².
