Myanmar’s steeplechase towards renewable energy

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.

Panasonic combines fuel cells, batteries, PV to power factory in Japan

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.

Molecular thermal energy system can store solar energy for 18 years

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).
