Energy Storage

The world’s biggest solar PV and storage project is set to get even larger with the Singapore-based Sun Cable announcing it plans to increase the renewable energy generation and storage capacity of the $26 billion Australia-ASEAN Power Link being developed in northern Australia.

A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.

The battery was built with a new catholyte and a symmetry-breaking strategy, which consists of changing the symmetry of the redox-active organic molecules instead of using the common approach of attaching a hydrophilic functional group.

Lithium-based energy storage volumes in the U.S. are expected to grow by multiple orders of magnitude in the coming years, with a 1000% capacity increase by 2023.

The risks posed to renewable-energy projects by Australia’s uncertain climate change policies and hamstrung regulators, have become a concerning brake on investment. Adjusting settings to reduce those risks would revitalise investor sentiment and vastly reduce the cost of implementing the country’s switch to renewables, says the Clean Energy Investor Group.

Imperatives meet opportunity. Corporate and utility goals for sustainability are driving a new group of investors to pick up the Australian renewable-energy resource and run with it. A new PwC report outlines how the new investor-developer partnerships could work.

China’s efforts to shift electricity generation from a coal-dominated system to a greener mix of renewables is not only centred on wind, solar and other technologies – the country is also rapidly pursuing energy storage. Vincent Shaw reports from Shanghai.

As technology redefines the delivery of network services, grid operators in remote areas the world over are searching for more cost-effective and reliable alternatives to traditional poles and wires. Standalone power systems are the solar application that is at the forefront of the switch, and they’re ramping up fast.

Victorian distribution network provider United Energy will deploy 40 custom-built community batteries across Melbourne’s southeast as part of an $11 million project designed to better manage the increasing penetration of rooftop solar PV and periods of peak demand on the network.

Residents in the West Australian town of Kalbarri are set to welcome the state’s largest renewable energy microgrid with state government-owned utility Western Power confirming commissioning and an operational trial of the hybrid system is due to commence next month.
