Reducing carbon dioxide emissions is the main driver of the energy transition, supported by the large-scale expansion of wind and solar energy production, writes Marcel Eijgelaar, researcher at DNV GL. Due to the variable output of these renewables, maintaining the balance between supply and demand is becoming more challenging with a higher need for grid flexibility and more volatile prices on electricity markets. New solutions are emerging, from battery storage to hydrogen electrolysis
