Utility Scale Storage

Analysts at Bloomberg New Energy Finance say the lowest-cost projects financed in Australia, China, Chile and the UAE in the last six months hit a levelized cost of energy of just $23-29/MWh and the best solar and wind projects will produce electricity for less than $20/MWh by 2030.

Researchers from Deakin University in Australia claim their battery chemistry is based on a new class of electrolyte material which carries no risk of uncontrolled thermal events and represents a viable alternative to rechargeable lithium-ion batteries.

Earlier this year, when a landmark tender by India’s nodal agency for solar energy, Solar Energy Corporation of India (SECI), concluded the largest solar-cum-storage tender globally (~3 GWh of storage connected to 1.2 GW of solar), it highlighted a critical challenge India faces in bringing solar energy to scale: battery storage technologies.

Prospective bidders for 34 MW solar project in Telangana and 14 MW solar plus storage project in Ladakh have been asked to submit any queries online as pre-bid meetings get cancelled due to Covid-19 lockdown. Further, bidding deadline for Ladakh project has been revised to June 1.

India’s energy storage juggernaut is on a roll with the country discovering the cheapest renewables cum storage tariff in history, anywhere in the world. The technology chosen is pumped storage. And by setting up an enabling environment, the government has signalled its commitment to boosting the market!

The government has been quick to announce major infrastructure projects for Ladakh, realizing the union territory’s potential for production of solar energy, which could be a boon for the entire country.

U.S.-owned analyst Wood Mackenzie expects solar demand to decline but predicts the market will recover, with the prospects for the energy transition remaining intact.

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.

Demand for batteries is going nowhere but up, as new factories seem to appear almost every week with promises to power electric vehicles, consumer electronics, and grid-connected storage. But the lithium-ion technology that all of these rely on is not without drawbacks, and a whole host of new storage solutions is eager to get out of the laboratory.

A report by Norwegian energy consultant DNV GL has considered the opportunity for long-term energy storage to play a role in balancing annual supply and demand fluctuations in a renewables-led grid. Using 58 years of Dutch weather and energy consumption data, the study found long-term solutions such as green hydrogen could make a valuable contribution – but perhaps not as much as some analysts believe.
