Covid-19 Impact: Electricity demand has dipped by 25% since mid March

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.

Cheaper flow batteries with new membrane

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.

Speeding up energy storage with pseudocapacitors

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%.

A plug-and-play solar-powered battery back-up solution for the home

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.

Large scale storage still some way off

Consultancy Bridge to India has looked into its crystal ball to predict India will add 10 GW of solar capacity this year and the same next year before deployment slows to 7 GW per year in 2022 and 2023, dogged by hurdles such as an inexplicable ongoing demand for new coal-fired power plants.

US based Triton Solar buys stake in startup Ushva Clean, JV to launch electric car

Leveraging Triton Solar’s battery technology and Ushva’s experienced team from IIT Bombay, the strategic alliance aims to develop one-of-a-kind car with the longest travel range on a single charge and unique user experience.

Balancing the renewable energy intermittency

Annual renewable energy balancing between resource-surplus and resource-deficit states can help solve DISCOM woes while ensuring their compliance to renewable purchase obligations.

EVs: India lacks authorized Lithium-ion battery recycling facilities

Any proponent can install such facility in the country, said Minister of State for Environment, Forest And Climate Change, noting that technologies are available for complete recycling of lithium batteries to recover valuable metals.

India’s lithium-ion battery imports increase fourfold in two years

China, Hong Kong and Vietnam are the top three nations exporting batteries to India. Chinese imports were worth $773 million in the last fiscal year with Hong Kong shipping $267 million worth and Vietnam $114 million, according to the Ministry of Commerce.
