While lithium-ion continues to dominate big project announcements worldwide, three providers of long-duration non-lithium battery technologies have claimed various milestones in commercialisation.
Sodium-sulfur (NAS) batteries made by NGK Insulators will be supplied by a subsidiary of chemicals company BASF for power-to-gas projects by South Korean company G-Philos in global territories.
Long duration energy storage is an “essential” technology to help accelerate renewable deployment, according to the US Department of Energy’s Dr Imre Gyuk, but will require “appropriate regulatory frameworks”.
Norwegian firm EnergyNest is to deploy its thermal battery storage technology at a manufacturing plant in Austria.
Recommendations made to the government of India as it prepares to publish its union budget for 2020 from industry group India Energy Storage Alliance (IESA) include measures to support both the upstream of industry and the downstream of clean energy deployment.
By the middle of the 2020s, using hybrid ‘portfolios’ of batteries and renewable energy sources will economically outperform existing gas power plants, while the combination of technologies is already cost-competitive with building new gas plants, a new report from the US-based Rocky Mountain Institute has said.
Duke Energy latest utility to test the technology, while manufacturer's partnership aims to introduce UK version next year.
Vionx, National Grid and the US Department of Energy have teamed up to install a 3MWh flow battery-based energy storage system in Massachusetts.
While lithium-ion is rapidly racing ahead to become the “de facto grid storage solution” and is the most popular technology choice by far, vendors of other types of batteries are also targeting the market, with varying degrees of success.
