New method to measure solar-powered hydrogen production

Indian researchers have used an “adaptive neuro-fuzzy inference system” to assess the performance of hydrogen production backed by a photovoltaic-thermal collector. They claim it can be applied to other hydrogen production systems.

New central inverter from Kehua

The 4.167 MW inverter has a reported efficiency of 99.02% and a European efficiency of 98.7%. The Chinese manufacturer claims the inverter’s DC parallel connection ensures the continuous operation of devices and increases the overall utilization rate by 1%.

Organic redox flow battery with PEDOT electrodes

Swedish scientists have developed a redox flow battery with polymer electrodes, based on a special conductive polymer known as PEDOT. The battery features a water-based electrolyte based on a solution of redox quinone molecules, which can be extracted from forest-based materials.

LG unveils AC module with own microinverter

The South Korean manufacturer has launched a new 60-cell panel with a power output of up to 365 W. The 21.1%-efficient module features a 320 W microinverter with an efficiency of 97%.

Floating solar plant with LCOE of $0.051/kWh comes online in Malaysia

The 13 MW array was deployed in the Selangor state on the west coast of Peninsular Malaysia. The plant is selling power to local utility TNB under a 21-year PPA. The project’s levelized cost of energy is MYR 0.21608 ($0.051).

Japan’s largest solar-plus-storage plant is now operational

Softbank has energized a 102.3 MW solar park backed by 27 MWh of lithium ion storage capacity. The project was built on 132 hectares of land near the town of Yakumo, in the northern island of Hokkaido.

Poland added 421 MW of PV in August-September period

The country’s cumulative installed PV power hit 2.68 GW at the end of September. Newly installed capacity for the first 10 months of the year has surpassed 1.3 GW.

Nobel Prize-winning auction geniuses want to apply their findings to renewables

Stanford professors Paul R. Milgrom and Robert B. Wilson were awarded the 2020 Nobel Prize in economics for developing a new auction theory and new auction formats for goods and services. Their findings were already successfully used in the electricity energy sector and may now meet the challenge on how to better shape clean energy procurements.
