Sodium-ion batteries for EVs, renewables storage

US scientist have developed a new electrolyte design for sodium-ion batteries to improve their long cycling performance. The low-solvation electrolyte was designed for high-voltage sodium-ion batteries, which retained 90% of their capacity after 300 cycles.

‘Entirely novel’ mechanochemical breakthrough for storing hydrogen

Researchers at Melbourne’s Deakin University have discovered a novel way to separate, store and transport large amounts of gas. The method, they say, is efficient, affordable and creates no waste – carrying huge implications for the burgeoning green hydrogen industry and for the energy transition at large.

New micro-inverter series from China

Beny Electric unveiled a micro-inverter series with efficiency of up to 97.5% and a European efficiency of up to 97%. The micro-inverters are available in three different versions with a rated power output of 550 VA, 700 VA, and 2,800 VA, respectively.

Oil and gas reservoirs are cheapest options for underground hydrogen storage

New research from Ireland shows that depleted oil and gas reservoirs may be used to store hydrogen at a cost of US$1.29/kg (AU$1.9/kg). According to the researchers, underground hydrogen storage may benefit from the technological maturity of the geologic storage of natural gas and CO2, which are associated with decades of established knowledge.

UQ targets testing platform to fast-track large-scale grid connections

University of Queensland researchers will seek to develop and test a new platform designed to help streamline the process of connecting large-scale renewable projects to the grid after landing a $498,000 grant from the Australian Renewable Energy Agency.

New method to evaluate performance, LCOE of elevated agrivoltaics

Scientists in Belgium have developed a way to assess elevated agrivoltaic projects, by calculating key performance indicators such as energy yield and levelized cost of energy (LCOE). They have found that shade-tolerant crops such as potatoes could potentially be paired with around 1,290 GW of PV capacity in Europe.

Weekend read: First notes of a West Australian symphony

Project Symphony provides a glimpse into Western Australia’s energy future, argues the project’s communications lead, Megan Allan. With a large, islanded network featuring high levels of rooftop PV penetration, the pilot on Western Australia’s grid is aggregating residential PV into a virtual power plant (VPP) to participate in a simulated bidirectional wholesale electricity market.

Global electrolyser market to reach 8.5 GW by 2026

GlobalData has predicted that the global electrolyser market will hit 8.52 GW by 2026. BP and Thyssenkrupp have agreed to cooperate on the use of hydrogen in the steel sector, while electrolyser supplier Nel Hydrogen has secured orders in Australia and Denmark
