Saturday read: Battery performance, uncovered

Batteries are taking the energy world by storm. From residential home storage systems to large-scale installations, today’s society increasingly relies on powerful batteries. And, as we all know, with great power comes great responsibility. But, how can we ensure that our use of batteries today is responsible, cost-effective, or even safe? Kai-Philipp Kairies, CEO of Accure Battery Intelligence, shares some of his experience gained from monitoring more than 750 MWh of various storage applications.

Queensland to build “common-user” vanadium processing plant

The Queensland government will put “at least” $10 million towards constructing a common-user facility to process vanadium from the state’s vast deposits, allowing multiple small mining operations to access the facility with the ambition of kickstarting downstream battery storage industries in the state.

UK business claims to have ‘world’s most sustainable lithium-ion battery’

English manufacturer Aceleron claims every component of its devices can be accessed for replacement, repair or recycling, with the business’ co-founder stating the aim is to ensure ‘100% of the materials in our batteries will continue to be used for as long as possible – preferably forever.’

Queensland cleantech company wins grant to build manufacturing base in Australia

Brisbane’s eleXsys Energy has won a government grant which will allow the company behind Australia’s largest grid-connected microgrid to build its manufacturing base here in Australia.

“Crickey!” Rooftop solar makes South Australia the world’s first gigawatt-scale system to hit negative demand 

Rooftop solar drove two negative demand events in South Australia on Sunday, November 21, events which analysts are describing as a world-first for a gigawatt-scale power system.

Novel solar cell architecture to reduce silver costs, improve voltage

Developed by a U.S.-based start-up, the new manufacturing process is claimed to reduce silver consumption and improve solar module performance by up to 3 watts. It consists of connecting sub-cells in series within a single cell in order to increase the device voltage and without requiring cells to be physically broken and rewired.

Saturday read: Looking past PERC

While the adoption of large-format wafers has driven a wave of capacity expansion for PERC, existing manufacturers and new entrants continue to evaluate TOPCon and HJT. An increasing number of HJT pilot lines and gigawatt-scale capacity expansion projects are appearing, as manufacturers see the advantages of fewer process steps, higher efficiency ratings, and better yield rates. The localisation of equipment is also a driving factor. PV InfoLink’s Derek Zhao offers an update on the latest developments and process routes for HJT.
