China scraps energy storage mandate for renewable energy plants In a major policy shift towards electricity market liberalization, China has introduced contract for difference (CfD) auctions for renewable energy plants and removed the energy storage mandate, which has driven up to 75% of the nation's demand to date. S&P Global expects the move to reverberate throughout the global battery energy storage supply chain, further driving down prices that are already at historically low levels.

Unlimited energy storage in Europe Most studies of European 100% renewable energy overlook pumped-hydro energy storage (PHES), for the following, incorrect, reasons: there are few PHES sites; more dams on rivers are required; large areas of land are flooded; large amounts of water are required; there is a heavy environmental cost; and the capital cost of PHES is high. All these perceptions are wrong.

The role of battery energy storage systems in sustainable data centers While many data centres have started using solar power as part of their energy sources, they still depend on grid energy because of regulatory issues like discom regulations and banking policies. To enhance the use of green energy and lessen reliance on fossil-fuel-based grid electricity, combining battery energy storage systems (BESS) with hybrid solar and wind power systems is a practical solution.
