Polluting energy sources received more than $3 trillion from the EU and 19 of the world’s largest national economies over that four-year period, despite G20 members having pledged to phase-out fossil fuel subsidy and address climate change back in 2009.

A gigafactory, as the name indicates, is a facility that aims to produce Li-ion cells at a gigawatt-hours scale of total capacity, so they can then be used in electric vehicles or stationary storage applications. The global production capacity of Li-ion cells is expected to reach 740 GWh by the end of 2021 – almost a threefold increase from 2017 – and Europe will account for 8% of the total. João Coelho, an analyst at Delta-EE, looks at how Europe plans to catch up.

The volume of new PV generation capacity added in the first half was higher than expected, given the rising input costs seen in recent months, but solar was nevertheless outpaced by new wind farms in the first six months of 2021.

A 125 kW/500kWh storage unit will be tested by China’s National Photovoltaic and Energy Demonstration Experimental Center. The storage system will be provided by Canadian specialist VRB Energy.

Indonesia will catch the eye too over the next nine years, according to Wood Mackenzie analysts, as its market grows from 300 MW to 8.5 GW.

According to Asia Europe Clean Energy (Solar) Advisory Co. Ltd, demand for solar PV in China could “effortlessly” surpass 100 GW in 2022, following a year of “flat” demand in 2021. It adds that a “massive overcapacity” situation in the production sector is looming. Meanwhile, the distributed solar PV market is on track for huge growth, with potential for annual demand to reach upwards of 20 GW+ from next year.

State body the NEA has given its provincial offices until July 15th to suggest counties where a solar mandate – which rises to at least half of all government roof space – can be rolled out. Selected companies will be awarded whole-county contracts.

Researchers from Hong Kong have applied a novel charge-reinforced, ion-selective (CRIS) membrane to a polysulfide-iodide redox flow battery they had built in 2016. The redox flow battery showed a capacity decay rate of just 0.005% per day for 1,200 cycles, and a lifetime with over 2,000 hours’ cycling, which the academics said corresponds to approximately three months.

The Biden Administration’s decision to ban solar imports from four Xinjiang-based polysilicon manufacturers, Hoshine Silicon, Daqo, East Hope, and GCL New Energy Material, has already raised concerns. One analyst warns of a “significant negative impact” across the U.S. solar industry.

Researchers in China have built a PV-powered air conditioner that can store power through ice thermal storage. The performance of the system was evaluated considering operating efficiency and stability and the scientists found that a device relying on a variable-speed compressor and an MPPT controller showed very good ice-making capability.
