Quantum Leap: Energy-storage may be the key to maximise power generation

Electricity generated by burning fossil fuels like coal and natural gas now constitutes nearly two-thirds of all power produced in the world. But by 2050, the scenario could be quite different, with solar, wind and other kinds of renewable energy responsible for a similar share of the total pie, according to Bloomberg New Energy Finance (BNEF).

Integral to this future are batteries that cost a lot less than today and can last longer. This is because unlike conventional energy, which can be generated through the day, solar and wind power are intermittent and the latter cannot meet peak energy demand in the evening without storage.

Alternatives to lithium-ion — the reigning battery technology used in phones, laptops, electric cars and smart grids — are being talked about.
