The colour code tells you which energy type was used to produce the hydrogen in gas form. Currently 95% of hydrogen is based on fossil fuels (grey hydrogen) still leading to high CO2 emissions. To make hydrogen a sustainable source of energy it must be produced by renewable energy (green hydrogen). However, huge investment in green hydrogen production is necessary to scale-up green hydrogen in the amount needed for the Green Transition.
Energy efficiency means being independent from Russia’s oil and gas, focusing on renewable energy sources and innovation at EU level. Renewable energy usage should be reflected in the EU’s ambition by more than 40% by 2030, with a particular focus on hydrogen. Energy efficiency is strongly related to energy waste, in the sense that at EU level there should be a new behavior towards minimizing consumption and waste in general.
