The power ministry has announced that the exemption on grid charges is now available to solar and wind projects to be commissioned up to June 30, 2025. The waiver is also allowed for pumped-hydro storage and battery energy storage system projects.

The BWRO unit, which has a treated water production capacity of around 11.80 ​L/h, was built with a pre-filtration module, a high-pressure DC pump, an RO module, and a post-treatment module. The PVT system was designed to meet the energy requirement of a high-pressure DC pump and a diaphragm-type circulation pump utilized to circulate soft water beneath the PV module for the active cooling of the panel itself.

An international research team has designed a residential solar-plus-storage system based on gravity. The system was built with a solar power generator, a bulk booster charge controller, an inverter, a solenoid device, a deep cycle battery, a pulley block, a geared motor, a microcontroller, and wire ropes. Its creators said the system is ideal for regions with high solar radiation. They found that, due to its high electrical requirements, the system needs to rely on high-power solar modules with an output of over 500 W.

Ruchi Gupta is a research fellow at the University of Geneva’s Institute for Environmental Sciences. She focuses on how flexibility options, such as sector coupling with hydrogen production, can support renewable energy integration and decarbonize a wide range of sectors.

JSW Steel will bring industry majors and the government together for hydrogen commercialization in the steel and cement sectors. CSIR-National Chemical Lab would work closely with the private sector on hydrogen development projects. Scottish Development International (SDI) brings the expertise from the implementation of large-scale hydrogen projects in Scotland.

With the draft National Electricity Policy (NEP) 2021, India is providing the right policy direction for this decade of the energy transition. Yet, there is room for further improvement. 

International researchers have placed a low-dimensional metal-halide perovskite capping layer on top of a metal-halide perovskite film to provide hermetically sealed encapsulation and enhanced photocarrier properties. The cell has a short-circuit current density of 23.5 mA.cm2, an open-circuit voltage of 1.15 V, and a fill factor of 0.779.

A €4.8 million EU-funded research project is aiming to develop a process that allows recovering all components of a photovoltaic module.

Often sidelined by nickel and cobalt when it comes to batteries, the metal manganese is finding proponents in science and industry – in particular, by those attempting to avoid supply and cost issues. Ian Morse reports on the role of manganese in battery cell production.

Scientists in Germany have developed a new process for deposition of silicon dioxide layers during cell production. Without the need for high pressure, flammable gases, or vacuum conditions, the process could lead to cost reductions for cell manufacturers, provided it can be developed and applied in a large-scale production setting.
