Energy Storage

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.

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.

The state-run power company wants to explore the feasibility of using hydrogen instead of diesel for back-up power and micro-grid application.

An Institute for Energy Economics and Financial Analysis (IEEFA) report says the sale of power in the futures market will benefit renewable energy developers and distribution companies alike.

Telangana-based Visaka Industries will set up electric vehicle (EV) charging stations powered by its ATUM integrated solar roof. According to the company, the ATUM solar roof, with PV panels integrated on cement boards, can generate 40% more clean power in the same given space than any other solar solution.

Separating generation from storage usually delivers higher value, but it may also deliver higher costs, the report said.

A prototype of a cement-based battery has been developed in Sweden for potential applications in buildings. Its creators claim it could become a solution to store electricity from rooftop PV and they do not exclude that it could also be used for the storage of large-scale renewables.

The nation maintained the highest score of 62.7 for solar in the latest edition of Ernst & Young’s renewables attractiveness index. It ranked third for overall renewable energy investment.
