‘Hybridising’ energy storage systems by combining lithium-ion and flow batteries, shares the power and energy application workloads between the two types of battery and can prolong their life expectancy, a representative of Thai engineering firm TSUS Group has said.

UK company Solarcentury has commissioned two solar-storage-diesel mini-grids in rural communities in Eritrea that are far away from the grid and have relied purely on diesel power until now.

The Asian Development Bank (ADB) has agreed to part-fund a US$53.2 million undertaking to power Tonga with renewable energy, including the installation of 22.2MWh of energy storage.

Perth-based Hybrid Systems and BayWa r.e. have reaped the lion’s share of the first round of a programme to roll out ‘standalone power systems’ (SPS) across Western Australia.

Following a report on Friday that Hawaiian Electric has contracted PPAs with 75MW of solar projects including battery storage with developer Clearway, the utility has put before regulators proposals for five other grid-scale projects.

Arlington Energy, a clean energy investment group, has announced plans to build out a 1GW portfolio of energy storage and gas peaker projects across the UK after securing initial funding of £200 million (US$255 million) from an offshore fund of institutional investment.

Increasingly, solar energy and behind-the-meter battery storage assets are being deployed on an ‘as-a-service’ basis and system integrator Younicos has decided to replicate the strategy for microgrids.

Islands are particularly vulnerable to the impacts of natural disasters such as hurricanes. John Merritt of Ideal Power looks at some of the emerging solutions to building more resilient energy systems through the deployment of microgrids that combine multiple energy generation and storage technologies.

Toshiba and NRG Energy have completed a new battery energy storage system that will benefit the Electric Reliability Council of Texas’ (ERCOT) grid.

A test and demonstration facility operated by South Africa’s main utility Eskom will trial Primus Power’s flow batteries, after a local developer was awarded a grant for the project by the US Trade and Development Agency (USTDA).
