New Delhi, April 2 -- Battery Energy Storage Systems (BESS) is the biggest challenge to meet the net-zero emission norms by 2050, according to a report by BofA Global Research.

The transition to a net-zero emission world requires a complete transformation of energy systems to move away from fossil fuels toward renewable energy sources like solar, wind, and hydro.

But, solar power generation depends on sunlight, which means no energy is produced at night, and production decreases on cloudy days. The same applies to wind energy, as power generation varies depending on wind speed, leading to fluctuations in power output.

So, unlike fossil fuel power plants, both the wind and solar energy plants can destabilize the grid and cannot be turne...
