Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.

Myanmar’s government has announced a plan to increase conventional and renewable energy generation to address electricity shortages. Reports from Burmese exiles, however, detail increasing issues for the construction of large scale solar projects tendered prior to the military coup in February 2021 and Chinese inverter manufacturer Sungrow said the project it secured in the country’s first tender has been canceled.

Japan’s Panasonic claims its new pilot solar-plus-hydrogen facility marks the first attempt to create a factory powered by 100% renewables, via the full-scale use of hydrogen.

New research has categorised all existing fault detection and localisation strategies for grid-connected PV inverters. The overview also provides a classification of various component failure modes and their potential causes in a tabular form.

Developed by a Chinese-Swedish research group, the device is an ultra-thin chip that could be integrated into electronics such as headphones, smartwatches and telephones. It combines a Molecular Solar Thermal Energy Storage System (MOST) with a micro-fabricated system that includes a thermoelectric generator (TEG) with a low-dimensional material-based microelectromechanical system (MEMS).

The device is based on a standard, two-electrode electrochemical cell containing conductive polymers, a carbon-graphene hybrid, and a non-flammable liquid electrolyte. The battery cells were tested to perform for 12,000 cycles at 100% depth of discharge.

The UK Department for Business, Energy and Industrial Strategy has published new research showing that hydrogen leaks could have an indirect climate-warming impact, partly offsetting efforts to reduce carbon dioxide emissions.

US researchers have proposed the use of hydraulically fractured oil and gas wells to store renewable energy via compressed natural gas, with the levelised cost of storage potentially coming in at US$70/MWh and US$270/MWh. They said wells could also be used to store other renewable gases such as carbon dioxide or hydrogen in the future.

A group of international scientists has investigated the potential use of radiative cooling in PV systems, in a newly published review focusing on challenges and opportunities for the passive cooling technology.

Bosch’s new solid oxide fuel cell prototype has an electrical efficiency of more than 60% and an overall efficiency above 85%. It also has a targeted power output of 10 kW and can produce up to 3 kW of thermal energy.
