Battery Storage Costs to Decrease Up to 66pc by 2030 – Irena

Date : Oct 17, 2017

The cost of battery storage for stationary applications could fall by up to 66 per cent by 2030, according to a new report published by the International Renewable Energy Agency (Irena).


An intergovernmental organization based in Abu Dhabi, UAE, Irena aims to promote adoption and sustainable use of renewable energy. It was founded in 2009 and its statute entered into force on July 10, 2010.


The falling price of batteries could stimulate 17-fold growth of installed battery storage, opening up a number of new commercial and economic opportunities, said the Irena report.


Launched during the ‘Innovation for Cool Earth Forum’ in Tokyo, Japan, Irena’s Electricity Storage and Renewables: Costs and Markets to 2030 assessment of electricity storage in stationary applications also found that global storage capacity could triple if countries double the share of renewables in the energy system.


"As storage technology improves and prices decline, both utility-scale and small-scale, distributed applications could grow dramatically, accelerating renewable energy deployment," remarked Irena director-general Adnan Z. Amin.


"In this dynamic, low-carbon energy environment, now is a crucial time for storage technology," noted Amin.


"This research demonstrates that the business case for renewable energy continues to strengthen, thus positioning it firmly as a low-cost and secure source of energy supply," he added.


The report, which is focused on stationary applications, highlights that while pumped-hydro systems currently dominate total installed power storage capacity, with 96 per cent of the installed electricity storage power globally, economies of scale and technology breakthroughs will support the accelerated development and adoption of alternative storage technologies, such as lithium-ion (Li-ion) batteries and flow batteries.


Stationary electricity storage can directly drive rapid decarbonisation in other key segments of energy use, such as in the transport sector where the viability of battery storage for electric vehicles (EVs) is improving fast, said the report.


At the end of 2016, the cost of Li-ion batteries had fallen by as much as 73 per cent for transport applications from 2010, it stated.


While Li-ion batteries in stationary applications have a higher installation cost than those used in EVs, in Germany, small-scale Li-ion battery systems have also seen their total installed costs fall by 60 per cent between the fourth quarter of 2014 and the second quarter of 2017.


"The growth of lithium-ion battery use in electric vehicles and across the transport sector over the next 10 to 15 years is an important synergy that will help drive down battery costs for stationary storage applications," remarked Dolf Gielen, the director of the Irena Innovation and Technology Centre and an author of the report.


"The trend towards electrified mobility will also open up opportunities for electric vehicles to provide vehicle-to-grid services, helping feed a virtuous circle of renewable energy and storage integration," he stated.


"Storage technology will deliver service flexibility to the grid and electricity storage to small-scale rooftop solar applications in markets where commercial and residential electricity rates are high, and grid feed-in remuneration is declining," he added.
