Scientists in India fabricated a redox flow battery based on zinc and iron that showed strong storage characteristics and no signs of degradation over 30 charge-discharge cycles. The battery also showed no signs of dendrite formation, overcoming one of the key hurdles for redox-flow batteries based on these low-cost, abundant materials.

The Indian Railways initially plan to convert diesel-powered trains in the 89km Sonipat-Jind section of Northern Railway to run on hydrogen. The hydrogen fuel cell retrofitment kit, along with the balance-of-plant and energy storage and hydrogen storage modules, will replace the existing power-train items onboard 1,600HP diesel-electric multiple unit (DEMU) rakes.

South-East Asia’s biggest floating PV installation is under construction by Masdar and Indonesian energy company PT PJB. The two companies secured a PPA for the project with state electricity company Perusahaan Listrik Negara (PLN) in January 2020. The agreed tariff is US$0.0581/kWh.

Researchers in China have developed a smart solar window tech based on a photovoltachromic device that is able to achieve a high pristine transmittance and to be self-adaptable to control indoor brightness and temperature. The device was assembled via a full solution process in an architecture incorporating glass, a fluorine-doped tin oxide (FTO) layer, a perovskite-based PV cell, an electrochromic gel, another FTO layer, and glass.

Developed by a Vietnamese-Korean research group, the complex PV device was built with a bottom bifacial crystalline silicon perovskite-filtered heterojunction sub-cell that is able to absorb all solar spectra in the short-wavelength range.

Developed by Chinese researchers, the novel design methodology consists of utilising metal brackets as mounting structures, conventional solar panels, and a grooved glass plate placed between the solar panels. According to its creators, it ensures a farmer’s average income increases by 5.14 times, including the solar power generation business. A system built with this approach should cost around €715 (AU$1145) per kW installed.

Australia-based Fortescue Future Industries has partnered with JSW Energy arm on green hydrogen production and application in India.

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

The U.S.-based manufacturer is planning a vertically integrated thin-film solar module manufacturing facility in India. The factory will likely be built in Tamil Nadu and become operational in the second half of 2023.

Indonesia, the second-biggest coal exporter in the world, is now taking more steps to reduce its dependency on “black gold” as it starts to consider clean energy.
