The Hydrogen Stream: US scientists hit PV water-splitting efficiency of 20.8%
US researchers have developed new integrated halide perovskite photoelectrochemical cells, while Fortescue Future Industries has revealed plans to acquire a hydrogen project from Nikola in Arizona.
Transnational grid across Sub-Sahara Africa may help spur renewables deployment
An international research group has proposed to build a Sub-Sahara Africa (SSA) central grid across 12 countries in order to reduce energy poverty. The proposed transmission line would touch Mali, Niger, Nigeria, Chad, Sudan, Ethiopia, Uganda, Kenya, Tanzania, Burundi, Mozambique, and South Africa.
Separator tech to prevent battery fires
Nuvola Technology says it has developed a direct deposition polymer separator technology that can eliminate the primary cause of lithium-ion battery fires.
MIT spinoff introduces new liquid metal battery system
Ambri has advanced its collaboration with Xcel Energy for a long-duration energy storage project.
Thermal energy storage system based on recycled ceramics
Serbia-based Storenergy has developed a thermal energy storage (TES) solution that uses recycled ceramics as the storage medium. It says its solid-state storage solution is designed to ensure long lifespans and low maintenance costs.
Green light for new big batteries in Australia
The government of the Australian state of New South Wales has provided planning approvals for two new grid-scale batteries. They will deliver a combined 540 MWh of energy storage capacity to support the state’s rapidly changing energy market.
The Hydrogen Stream: EU, Argentina, Chile, Uruguay to partner on hydrogen
The European Commission and the European Investment Bank have agreed to collaborate with Argentina, Chile and Uruguay on hydrogen, while Masdar, Mitsubishi and Inpex have said that they will use green hydrogen to produce e-methane and polypropylene.
Australian developer plans 900 MW of solar for green hydrogen project
Traditional owners in Western Australia will partner with advisory firm Pollination to develop what could be Australia’s largest solar farm. The move is part of plans to build a gigawatt-scale green hydrogen and ammonia project in the northwestern part of the country.
Hybridizing PV, sand storage, solar thermal energy for steam generation
A Finnish-Swedish consortium has designed a hybrid system that uses photovoltaics and solar thermal energy separately to provide steam to industrial facilities. The PV unit is coupled to a sand-based thermal storage system and reportedly contributes to lower the levelized cost of energy of the entire system.
Sodium-ion battery fleet to grow to 10 GWh by 2025
Global demand for sodium-ion batteries is expected to grow to just under 70 GWh in 2033, from 10 GWh in 2025, at a compound annual growth rate (CAGR) of 27%, according to UK-based market research company IDTechEx.
