Energy Storage

Analyst IHS Markit has predicted storage will rebound this year following its first year-on-year decline in 2019. The technology is being rolled out at pace despite Covid-19 with state-level policies set to keep the US the global capital for the next five years.

US-based esVolta will deploy the Edison Analytics software platform across its battery energy storage projects in North America. The software is expected to result in savings of $450,000 annually for esVolta by reducing excess battery degradation through improved heating and discharge management. 

The program aims at supporting the development of innovative electric vehicle (EV) solutions like extending range through battery capacity improvements, and battery management, fast charging infrastructure, and mobile charging solutions for emergencies. Two startups shall be supported each year with up to INR 80 lakh each to complete proof of concept and develop prototypes. 

Companies investing in battery energy storage have historically relied on trust in the major brands supplying the batteries and complete systems. However, with the absence of international manufacturing quality standards, increasing price pressure on major brands, and the proliferation of low-cost manufacturers, buyers and investors are being forced to address quality risks with batteries. Ian Gregory and Benjamin Sternkopf of PI Berlin discuss the need for independent quality assessment in energy storage.

Delinking the battery (which accounts for 30-40% of the total vehicle cost) will bring the upfront cost of the electric 2-wheelers (2W) and 3-wheelers (3W) to be lower than internal combustion engine counterparts. The battery could be provided separately by the original equipment manufacturer or the energy service provider. 

The Indian energy thinktank and the US-based consulting firm will research to demonstrate the viability of hydrogen as a sustainable solution for India’s energy needs. 

Researchers from India’s Centre for Nano and Soft Matter Sciences (CeNS) have developed a coordination polymer based catalyst for hydrogen production that exhibited exceptionally high durability for 70 hours at a high current density of −300 mA/ cm2.

With demand for cleaner forms of energy and a greater need for flexibility and reliability in the power supply, the role of battery energy storage is critical. Innovation in battery technology is essential to match demand growth and the shift in technical requirements. Predictions of 400,000 MWh of battery storage required by 2025 means that all battery technologies will play a role in contributing to a clean energy future.

The government is acquiring lithium mines abroad to ensure raw material availability for electric vehicle battery production. Among other technology alternatives for EVs, it is looking at developing indigenous hydrogen fuel cells with hydrogen derived from biomass.

A solar array – complete with battery storage and remote monitoring and control capabilities – has been transforming brackish groundwater into fresh drinking water in the village of Beyo Gulan in the Somaliland desert since 2018. The installation was developed by Germany’s Phaesun. Its unique combination of low-maintenance electrodialysis desalination with PV saw it pick up an Outstanding Projects award from The smarter E. Phaesun’s Géraldine Quelle and Florian Martini say they are honored by the plaudits, and are readying the system for series production.
