Energy Storage

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.

The software giant has begun testing hydrogen fuel cells as a back-up power source at one of its U.S. data centers. A 250 kW pilot system successfully powered part of the facility for 48 hours and the company is now eyeing 3 MW systems to replace back-up diesel generators.

The Ministry of New and Renewable Energy has specified how procurement of back-up grid capacity will work for electricity distribution companies. The rules consider energy storage solely as part of the 51% clean energy requirement, and instead contemplate coal – with a variable price tariff element – as necessary for evening out supply.

Scientists in the U.S. claim to have demonstrated an inexpensive, long-life, safe and eco-friendly redox flow battery. The device is said to offer coulombic efficiency of 97.9%, thanks to functional electrolyte additives, pH and elevated temperature.

The Solar Energy Corporation of India has extended the bidding for its solar-plus-storage project in Ladakh by one month. The revised deadline is now September 30.

Rooftop solar is the obvious choice to save on electricity costs for businesses as they look to preserve capital and find ways to cut expenses post Covid-19. 

To support renewable energy integration, the government aims to make the thermal capacity flexible, almost 55% in the first stage and gradually extend it to the entire capacity.

Mobility in rural Kenya is currently flooded with unsustainable CO2-emitting motorcycles that pose a threat to the environment and public health. But the electric tricycle is an environmentally friendly alternative, and Solar E-cycles – a homegrown Kenyan startup – believes a leasing model could unlock a ton of three-wheeled potential.
