Previously known for its automotive activity, CATL is turning to another promising sector to generate demand for its battery cells. With the first few hundred thousand Japanese solar households seeing their 10-year FIT contracts expire, demand for small scale storage is on the rise

Batteries of the type have traditionally been used for long-duration storage applications. Now though, it seems vanadium is making an entry into the fast-paced world of ancillary grid services.

Hyundai has unveiled its new hybrid, the Hyundai Sonata, complete with integrated solar cells. The Sonata’s unveiling joins Toyota and Lightyear in integrating solar PV with EVs.

Study claims that investment in a new 1GW nuclear power plant leads to average losses of approximately 4.8 billion euros. It further argues that the technology’s dangerous radioactivity emissions and proliferation risks do not qualify it as a ‘clean’ energy solution to be considered for addressing climate change. Yet still, governments are incorporating the technology into clean energy plans around the world.

A report by the U.S.-based Rocky Mountain Institute has modeled scenarios for the deregulation of electricity markets in China. The report finds the implementation of a spot market would drive increased integration of renewables and provide significant reductions in costs and emissions.

California based Hanergy subsidiary Miasolé has broken its own internal record for thin film cell efficiency, surpassing the 20% mark. The efficiency of 20.56% on a flexible substrate has been confirmed by U.S. National Renewable Energy Laboratory.

Scientists from the University of Kansas say adding a layer of two-dimensional semiconductor molybdenum disulfide can greatly improve the performance of organic solar cells. The research could also inform efforts to engineer the interface between layers in hybrid organic cells.

With EV sales continuing their climb, and overall carbon emissions targets getting more ambitious, stakeholders in the energy system will need to consider flexibility options from, among other points, EV charging. A large distribution system operator in the U.K. is now examining the options to remunerate customers for adapting their EV charging patterns to load profiles of the grid. If successful, the exercise may help mitigate grid infrastructure expansion costs.

Scientists at the University of California, Santa Barbara who are working with sodium-ion batteries have found that the unintended presence of hydrogen is to blame for many of the technology’s shortcomings in terms of degradation and performance loss. Keeping hydrogen out of the materials throughout production could allow sodium-ion batteries to achieve performance levels competing with their lithium-ion counterparts.

A floating solar array will be located in the North Sea near an aquaculture and an offshore wind power facility. The €2 million pilot project is being developed by a consortium including Tractebel, Jan De Nul Group, Deme, Soltech and Ghent University.
