The future energy system of the Netherlands and the European Union (EU) will have to be climate neutral. One of the requirements of this energy system is that it must also be secure. Energy security is to a considerable extent determined by security of supply: the certainty that the Netherlands and the EU will be able to obtain the amount of energy and energy related resources externally it needs to thrive, also in shifting geopolitical circumstances. The current frameworks to secure supply are related to an energy system based on fossil fuels, natural gas and oil in particular. Current policies are therefore focused on securing the supply of these resources. The future energy system will move away from fossil fuels and relies on fossil free electricity, hydrogen, renewable carbon and renewable heat. This fundamental shift translates necessarily into a whole new framework to monitor and secure security of supply as a key pillar of energy security. € 150.000,- excluding VAT
