After another record-breaking year, in which the US surpassed 1GWh of deployed energy storage and China began its programme of building flow batteries several hundred megawatts in size each, we canvassed opinion on what 2018’s biggest challenges and successes were. In this first part, we look at the challenges faced by the industry in 2018.

Work is underway on an energy storage project in South Australia that will use biogas to generate power to be stored in modules of molten silicon, from startup 1414 Degrees.

Hornsdale Power Reserve (HPR), the 129MWh battery energy storage system (BESS) deployed by Tesla and developer Neoen in South Australia in just 100 days, has been found to have had a positive impact on the local network.

Steven Marshall, the Premier of South Australia, has welcomed the start of assembly-line work at Sonnen’s new factory in Adelaide, while rival Tesla’s virtual power plant (VPP) in the state is beginning its second phase of development.

The economics of rural electrification using microgrids should be considered an investment for the future, akin to how Silicon Valley tech providers plough money into initially loss-leading products and services, the chief of developer and manufacturer Solar Philippines has said.

Redflow will provide 32 of its zinc-bromine flow batteries to two new children’s centres in its native Australia.

In order to address intermittency in its grid, the South Australian Government has introduced a AU$50 million (US$36 million) Grid Scale Storage Fund (GSSF) to help accelerate the deployment of new large energy storage projects, including pumped hydro, hydrogen, gas storage, solar thermal, bioenergy and battery storage.

Solar modules and deep cycle batteries have been stolen from seven secondary public schools in two municipalities in southern Palawan, in the Philippines.

Australian Vanadium (AVL) and VSUN Energy have signed an agreement to work with the Future Batteries Industry Cooperative Research Centre (FBI CRC) on developing vanadium extraction and processing skills, particularly in Western Australia.

State-run utility Electricity Generating Authority of Thailand (EGAT) is planning to facilitate 1GW of hybrid floating solar-hydro projects across eight dams throughout the country, while the national government is piloting large-scale battery energy storage.
