Energy Storage

The nation is already firmly positioned to lead the world in the clean energy revolution. Consolidating this position would unlock significant economic growth and competitiveness by attracting domestic and foreign investment, creating jobs, and improving public health.

The three-day event will connect the global investment community with Indian renewable energy stakeholders. It is expected to be attended by over 75 international ministerial delegations, over 1000 global industry leaders, and 50,000 delegates.

The electronics manufacturer says it will switch focus to solar panels and lithium battery storage as it launches an inverter series for rooftop PV.

The public sector energy company has opened a compact reformer plant at Delhi Transport Corporation’s Rajghat bus depot. The facility will produce hydrogen-enriched compressed natural gas as a bus fuel. A trial period will see 50 gas-powered buses run on the blended fuel with fuel economy and emissions monitored.

Swiss-based SmartHelio claims to have witnessed a near 200% jump in demand for its deep-data driven solar asset management solution, which plugs into solar panels or energy storage systems. Sales of the internet-of-things enabled, cloud product have leapt in the last six months.

MIT scientists have suggested used electric vehicle batteries could offer a more viable business case than purpose-built systems for the storage of grid scale solar power in California. Such ‘second life’ EV batteries, may cost only 60% of their original purchase price to deploy and can be effectively aggregated for industrial scale storage even if they have declined to 80% of their original capacity.

Disruptions in the industrial and commercial activities due to Covid-19 lockdown have further dented electricity demand in India which already registered a discernible decline in annual electricity demand. India’s electricity demand in the first 11 months of 2019-20 (April 2019-February 2020) grew by 2.2% (to 1191 billion units) compared with 5.4% annual growth in the same months of previous year.

US scientists claim to have discovered a membrane which could lead to cheaper large scale flow batteries. The material is an ion-selective, aqueous-compatible polymer with intrinsic microporosity known as AquaPIM and is said to have tunable thickness and high conductivity in aqueous electrolytes.

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 OneBox, from Indian manufacturer Vision Mechatronics, consists of a lithium battery, hybrid inverter and solar charge controller to give a hassle-free solution for electricity back-up during power outages. Solar rooftop owners are offered a grid feed feature to maximize net metering income from any excess power generated.
