To this end, we are building the scientific and technological, legal, economic and industrial law protection base for small-footprint energy technologies, especially H2 production/transport/storage/use and CO2 utilization (CCU). The two technology groups can play a significant role in sectoral integration in parallel, supporting each other, iin strengthening energy security of supply and achieving decarbonization goals.
