March 30 is the last date to bid for the solar capacity tendered by NTPC Vidyut Vyapar Nigam Limited. The project—to be set up on turnkey basis—shall come up at Panchet power station of Damodar Valley Corporation and shall be awarded through domestic competitive bidding followed by reverse auction.

Based in Gurugram, the factory is spread over 30,000 sq.ft and can produce 240 MWh of high-temperature battery storage solutions annually. These batteries can charge to 80% capacity within two hours and operate in excess of 55ºC, which makes them suitable for hot, humid tropical climates.

A report by Norwegian energy consultant DNV GL has considered the opportunity for long-term energy storage to play a role in balancing annual supply and demand fluctuations in a renewables-led grid. Using 58 years of Dutch weather and energy consumption data, the study found long-term solutions such as green hydrogen could make a valuable contribution – but perhaps not as much as some analysts believe.

The Climate Investment Platform launched by three multilateral bodies in September is now open for business and renewables companies in developing nations across 14 regions including south Asia could qualify for help with clean energy facilities, renewables-related grid improvements and energy efficiency schemes.

The International Water Management Institute is promoting the Solar Irrigation for Agricultural Resilience (SoLAR) initiative to expand the use of solar irrigation systems throughout Bangladesh, India, Nepal, and Pakistan. Proponents of solar irrigation pumps say that they can have a strong positive impact on groundwater.

Fuel cell systems provide sustainable electricity using hydrogen gas without the need of grid power as required by conventional battery backup systems, making them highly useful for applications like Emergency Operation Centres which need to respond immediately during an emergency situation with state-of-the-art communication systems.

Researchers in China have ranked some of the most commonly used battery chemistries according to parameters deemed important for grid-level storage. The team gave a score in each category and determined a winner – and it wasn’t lithium-ion.

The programme—co-funded by Swedish Energy Agency and India’s Department of Science & Technology (DST)—aims to develop technologies that can be commercialized after two years. While SEA has committed US$2.6 million over four years for research and innovation collaboration with India, DST will also fund a matching investment of Rs 18 crore to support Indian partners.

Scientists at Germany’s Helmholtz Zentrum Berlin have made a discovery they say could greatly increase the energy storage capacity of titanium-based ‘MXene’ pseudocapacitors, ultimately leading to faster-charging batteries. The group found adding urea molecules between MXene layers increased the material’s storage capacity by up to 56%.

The thin-film cell was manufactured through a low-temperature process and doping with alkali elements.
