A lot has happened since 2017. There's been enormous evolution in: - solar and wind electricity generation: drastic cost reduction, massive scale-up - interconnects: lower cost, strong growth, especially in the EU - green hydrogen ecosystem: incredible cost reduction, massive scale-up - battery storage: drastic cost reduction, massive scale-up - pumped hydro storage: eking out the last bits - other storage tech: liquid metal, compressed CO2, ... - heat pumps: massive scale-up, incremental efficiency improvements, also large scale sea source like Helsinki I'm especially hopeful when it comes to green hydrogen derivatives as energy carriers.
