Researchers in China have ranked some of the most commonly used battery chemistries according to parameters deemed important for grid-level storage. The team gave a score in each category and determined a winner – and it wasn’t lithium-ion.

Tasmania has committed to being 100% renewable by 2022 and remains well on track to meet this target ahead of schedule. But the island state says it is well placed to set a more ambitious goal, which would see it double its renewable production and help mainland Australia reduce its emissions.

The developer has confirmed a nearly $30 million write-down on its troubled Kennedy Energy Park and entered into a binding agreement on a $1 a share takeover bid from a consortium that includes Andrew ‘Twiggy’ Forrest’s Squadron Energy.

The South Australian Government has partnered with sonnen to offer 188 families a locally assembled sonnenBatterie as they rebuild their homes.

With a Commonwealth MoU in hand and a ‘flexible’ attitude to the regulatory processes governing transmission build in Australia’s National Electricity Market, the NSW Department of Planning and Environment is revving up its plans to develop a demonstrator Renewable Energy Zone.

Australia’s distributed energy resources — rooftop solar, batteries, smart devices — have become a force to be reckoned with, and AEMO has opened its DER Register to help integrate consumer assets into what is expected to become the world’s most sophisticated two-way energy market.

The Berejiklian government has launched a pilot program that will allow eligible Hunter residents to access interest-free loans for battery and solar-battery systems.

South Australia is seeing a surge of small-scale utility solar as the niche, particularly around the 5MW mark, can fly under the radar of much of the electricity network’s congestion woes. The newly completed Mannum Solar Farm Project is one such example.

The Australian network rule maker has ignored the plea of some of the biggest solar and wind project owners in Australia to change the way marginal loss factors (MLFs) are calculated. While it has acknowledged that transmission has failed to keep up the pace with renewable energy investment, it did not come up with any suggestion on what should be done to ameliorate the problem.

Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² flexible thin-film cell intended for building-integrated PV application. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.
