Distributed Storage

Scientists in India fabricated a redox flow battery based on zinc and iron that showed strong storage characteristics and no signs of degradation over 30 charge-discharge cycles. The battery also showed no signs of dendrite formation, overcoming one of the key hurdles for redox-flow batteries based on these low-cost, abundant materials.

A new report projects Lithium-ion technology to lead the Indian battery energy storage systems market by 2030 as prices for lithium iron phosphate (LFP) and lithium nickel-cobalt-manganese (NCM) battery technologies fall.

A British-Australian research team has assessed the potential of liquid air energy storage (LAES) for large scale application. The scientists estimate that these systems may currently be built at a cost between €300 and €600 per kilowatt-hour and that a positive business case could be favored by certain conditions, including a determined price structure in the energy market and the presence of a grid unable to support high levels of renewable energy penetration.

The company will initially launch 750 electric buses across key intercity and inter-state transit routes in Southern and Western India. To support the e-bus rollout, it is also building a captive charging infrastructure network across highways with 600 DC chargers of 180/240 kW capacity rating.

The adoption of local, community-based energy solutions like rooftop solar and batteries can help make the energy grid more flexible and reliable. Home solar and batteries will enable the growth of ‘prosumers’ who produce and share energy, as well as consume it.

The maintenance cost of an electric vehicle is estimated to be significantly lower than internal combustion engines, and studies show home solar furthers the cost savings and boosts carbon emission reductions.

Professor Thomas Nann told pv magazine Australia that a breakthrough idea was almost too simple: “Actually when we submitted the patent in the first place, the patent officers came back to us and said ‘well, that’s too trivial’ and we made exactly that argument – why did no one else do that then?” said Nann.

Convergence Energy Services limited, an arm of Energy Efficiency Services Limited (EESL), will set up electric vehicle charging points at Hindustan Petroleum Corporation Limited outlets in major cities including Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata, and Pune. The two partners are also identifying major highways across India where adequate charging infrastructure can be installed.

A new report says solar-plus-energy storage will become an attractive investment option for commercial consumers in India as early as 2023 for electricity bill reduction. For high-tariff paying residential consumers, the system will reach grid parity post-2027. The report findings are based on the levelized cost analysis of solar-plus-energy storage systems for consumers in the Indian State of Tamil Nadu.  

The scope of work includes supply, erection, testing, commissioning, and five-year warranty maintenance of the standalone solar photovoltaic power generators. Bidding closes on August 2.
