A 5 MW / 3.6 MWh solar-plus-storage plant is being built with sodium-sulfur batteries provided by Japanese specialist NGK Insulators in Mongolia’s Zavkhan Province. The project developer, Japan-based contractor JGC Holdings, wants to bring the facility online in the spring of next year.

The tender is aimed at procuring 2 GW of capacity in response to the chronic short-term electricity supply gap that is affecting the country and its mining sector. The South African government has selected three LNG projects that may secure around 60% of the awarded capacity and several renewable energy projects including solar, wind and storage. The procurement exercise attracted a lowest bid of $ 0.0998/kWh.

A US-Taiwanese research group has created a new spin coating method which they claim can be applied in the mass production of mini perovskite panels. The scientists used sulfolane as an additive in the perovskite precursor to convert the perovskite phase via a new reaction route. They demonstrated a mini-module with a power conversion efficiency of 16.06% and an active area of 36.6 cm2.

Have we reached a tipping point, from building the case with mining companies for deploying renewable energy … to where renewable energy is helping to build the case for mining?

Suppliers of encapsulant materials – plastic sheets that are heated to laminate together the components in PV module stacks – are rapidly expanding to keep pace with module manufacturing in Asia and other parts of the world. Ethylene-vinyl acetate (EVA) continues to dominate the market, but new developments in module technology are driving a slow shift to more costly polyolefins.

Solar module developers have long recognised the detrimental effects heat has on cell performance but West Australian company Sunovate has pointed to solar PV-thermal (PVT) technology as an opportunity to value add by improving efficiency.

The Indian developer has secured the revolving fund from 12 international banks. It will use the amount to initially finance its 1.69 GW hybrid portfolio of solar and wind projects to be set up in the Indian state of Rajasthan.

Tianjin Zhonghuan Semiconductor began building its new wafer manufacturing facility in the Ningxia Hui autonomous region. Shanghai Electric is setting up a hydrogen research center with the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences.

French research institute CEA-Liten has created a technique that consists of using a diamond wire to cut through the photovoltaic cells, separating the module’s glass front face from the polymer-based backsheet. The process is claimed to be low-polluting and low-energy.

The Chilean Minister of Energy and Mining has announced the signing of a memorandum of understanding to export green hydrogen to the Port of Rotterdam. The deal adds to the one signed with Singapore in early March to identify the best routes to reach Asian markets.
