Technology and R&D

Scientists in the United States pieced together data from hundreds of different sources, looking to establish the key factors that have led to consistently falling prices for lithium-ion technology since their commercialisation thirty years ago. They find that public-funded research, primarily in chemistry and materials science, has made the largest contribution to cost reduction. And they offer suggestions on policy and investment to ensure that the research can continue to make these important contributions to reduction in battery costs.

NREL scientists have unveiled a storage system based on a phase-change material that can store both thermal energy and electricity in a single device. According to the researchers, the new technology may be used to store excess electricity produced by on-site solar or wind operations in large scale buildings.

Hydrostor’s plant would be able to deliver 400 MW of electricity for 8 hours, and would be comparable in size to some of California’s largest fossil fuel power plants.

Queensland continues to attract massive hydrogen industry factories, with LAVO Hydrogen Technology today announcing it would establish a fuel cell manufacturing facility just south of Brisbane.

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.

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.’

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.

Developed by a spin-off of Dutch research institute TNO, the battery is claimed to offer higher energy density, longer lifespan and increased safety compared to conventional lithium-ion batteries. It will initially be applied in wearables and electric cars.

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.

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.
