Developed by Swedish manufacturer Azelio, the system stores renewable energy in recycled aluminium and has an electrical and thermal energy output, with a total efficiency of 90 %. One unit’s storage capacity reaches 165 kWh of electrical output and on top of that thermal energy between 55-65 degrees Celsius. Its modular configuration allows the deployment of projects with a capacity of up to 100 MW.

Singapore-based VFlowTech has secured funds to scale up manufacturing of its vanadium redox flow batteries. The company currently offers three modular products that can be scaled to multi-megawatt-hour systems.

Vietnamese manufacturer Irex has announced a new glass-glass solar panel with a power output of 265 W and a power conversion efficiency of 18.1%.

The system has dimensions of 834×417×1,766 mm and weighs 205 kg including the design panel. It achieves an electrical efficiency of 56% and can be connected with a hot water storage unit.

Dansk Solenergi ApS has developed a 13.6 kg tile that can be used for both new buildings and building renovation. The device is currently being produced in Denmark, where the company operates a 40 MW line.

A group of international researchers has observed how non-radiative charge recombination occurs in organic PV and claims to have identified a potential solution that could bring this solar tech closer to crystalline silicon in terms of power conversion efficiency.

Closed-loop pumped-hydro storage offers more chances to minimise environmental effects on water sources and overcomes the problem of finding suitable sites. According to an Australian research team, closed-loop systems could prevail on open-loop systems in the future and this trend is confirmed by another group of scientists from the United States.

The project includes a solar park coupled with what HDF Energy claims is the “largest green hydrogen storage of intermittent electricity sources” at 128 MWh. Importantly, the company also simultaneously announced expansion plans into Australia, saying its hydrogen technology will soon be available here, adding that it has “projects already in development for Australia”.

Storing hydrogen in carbon nanotubes and other nanostructures is still far from reaching commercial maturity. A Japanese research team, however, has developed a new simulation technology that may help better estimate the energy needed to favour the ideal interaction between hydrogen and its storage material.

The 97%-efficient microinverter has a power output of up to 960 VA and APsystems claims it is the most powerful dual microinverter in the world.
