India’s solar imports dipped 75% in ten months

Covid-19 disruption has been cited as the chief culprit as imports from China, Thailand and Vietnam slumped from April to January, but safeguarding duty also appears to have had an impact, with unaffected imports from nations such as Myanmar, Chad and Russia on the rise and Malaysian trade keeping steady.

Mounting interest for solar-linked bilateral deals in Russia

Under the current Russian energy regulatory framework, bilateral deals can be concluded between a seller and a buyer with a power distribution company mediating as a third party.

Nickel-salen for a battery that charges in 10 seconds

Scientists in Russia introduce a promising new material for battery energy storage, the product of more than three years of research. Incorporating a nickel-salen polymer into the cathode, the group demonstrated a battery that can charge and discharge ten times faster than today’s lithium-ion batteries. And though the battery still lags in terms of overall capacity, the group is confident that its discovery will lead to big improvements for lithium batteries.

New materials for organic redox flow batteries

Scientists in Russia have designed a whole series of new compounds that could serve as catholytes and anolytes in organic redox flow batteries. The materials promise to open up new pathways for further research, and overcome some of the challenges for organic redox flow batteries in commercial, large-scale energy storage projects.

Solar could help Azerbaijan consolidate gains in Nagorno Karabakh after recent conflict

That was just one of the revelations of the latest Dentons’ Guide to renewables investment in Europe, which also noted solar plants could be switched off in Slovakia, Ireland could go either way on clean power pricing, and Luxembourg is struggling with a surprising headache.

Holographic film to protect solar panels from overheating

Russian scientists have developed a holographic film based on prismatic concentrators that reduces the operating temperature of solar panels, including thermal-photovoltaic devices. They claim the patented, low-cost technique can even improve PV module efficiency in cloudy weather.

Russia introduces net metering for small-sized PV

The new net metering provisions came into force three years after the legislative process was launched. Power surplus will be sold to the grid at a rate of up to RUB2/kWh ($0.026).

Rosatom plans 2 GWh lithium-ion battery factory in Russia

Russian nuclear energy giant Rosatom has acquired a 49% stake in Enertech International, a South Korean lithium-ion battery specialist, and has announced plans to build a gigafactory at an unspecified location in Russia. The start of production is scheduled for 2025.

A ‘chemical fuse’ – voltage sensitive polymers in the fight against battery fires

A team of researchers from St. Petersburg say they can build a circuit interruptor that works directly into the current collector. The device operates via chemical reactions and would be thus more reliable than current battery monitoring system approaches.

Novel nanomaterial to replace graphite in lithium-ion batteries

Porous nanostructured microspheres made of copper, iron, and iron oxide were used by an international research team as negative anode material in lithium-ion batteries. The new technique is claimed to provide three times more capacity than batteries based on graphite anodes.
