The role of heat pump in heating decarbonization for China

Heating decarbonization is a major challenge for China to meet its 2060 carbon neutral commitment, yet most existing studies on China''s carbon neutrality focus on supply side (e.g., grid decarbonization, zero-carbon fuel) rather than demand side (e.g., heating and cooling in buildings and industry). In terms of end use energy consumption, heating and cooling accounts

Is pumped hydro a good option for energy storage?

However, pumped hydro continues to be much cheaper for large-scale energy storage (several hours to weeks). Most existing pumped hydro storage is river-based in conjunction with hydroelectric generation. Water can be pumped from a lower to an upper reservoir during times of low demand and the stored energy can be recovered at a later time.
