The article discusses the importance of electrification and the role of molecules in transitioning towards a sustainable energy system. While electrification is essential for lower energy losses and reduced carbon emissions, challenges such as grid overloads and excess green electricity on certain days pose limitations. Molecules like low-carbon hydrogen and CO2 storage are highlighted for their significance in achieving climate neutrality, especially in sectors requiring high temperatures and high energy density fuels. The article emphasizes the need for a balanced integration of electrons and molecules for a reliable and affordable energy system. It underscores the necessity of investments in power grid expansion, infrastructure for sustainable molecules, and storage capacity to facilitate a smooth transition towards a zero-emission economy. Policy recommendations include simultaneous investments in power grid expansion and sustainable infrastructure, with a focus on interconnection, storage, and backup capacity to ensure system reliability and affordability.
