Abstract: Disclosed are an energy management method, system, computer device and readable storage medium. The method includes: obtaining a first current output power and a previous output power of a first energy supplier; obtaining a current power change rate of the first energy supplier according to the first current output power and the previous output power; obtaining a first reference power of the first energy supplier according to the first current output power, the previous output power and the current power change rate; obtaining a second current output power of a second energy supplier; obtaining a second reference power of the second energy supplier according to the first current output power, the second current output power and the first reference power; obtaining current flow rates of first and second gas and a current furnace temperature; and obtaining a reference flow rate of the first gas and a reference furnace temperature.

Abstract: An energy storage system is provided for an electric vehicle. The energy storage system comprises a first energy storage source. The first energy storage source includes an ammonia tank configured to hold ammonia, an ammonia converter configured to receive ammonia from the ammonia tank and convert the received ammonia into hydrogen, and a fuel cell system communicating with the ammonia converter and configured to generate output power from hydrogen that is received from the ammonia converter.

Abstract: New layered double hydroxide materials useful as intermediates in the formation of catalysts are described, as well as methods of preparing the layered double hydroxides. Also described are catalysts suitable for catalysing the hydrogenation of CO2 to methanol, as well as methods for preparing the catalysts. The LDH-derived catalysts of the invention are active in the hydrogenation of CO2 to methanol, and show improved activity with respect to Cu/ZnO catalysts derived from copper-zinc hydroxycarbonate precursors.
