Abstract
Disclosed is a hybrid system in which a solid oxide electrolyzer cell (SOE), a solid oxide fuel cell (SOFC), and a carbon capture system (CCS) are coupled to each other, and more particularly to an SOE-SOFC-CCS hybrid system configured such that a solid oxide electrolyzer cell, a solid oxide fuel cell including a burner configured to burn off-gas, and a carbon capture system are systematically operated and such that by-products and waste heat generated as the result of operation thereof are recycled, whereby consumption of hydrogen and a fuel necessary for power production is minimized.
Claims8
An SOE-SOFC-CCS hybrid system comprising:
- a solid oxide electrolyzer cell (SOE);
- a solid oxide fuel cell (SOFC) comprising a reformer, a fuel heat exchanger (fuel HX) configured to heat a fuel produced by the reformer, a first air heat exchanger (air HX_A) configured to primarily heat outside air, a second air heat exchanger (air HX_B) configured to secondarily heat the primarily heated outside air, a stack comprising an anode configured to receive the fuel heated by the fuel heat exchanger and a cathode configured to receive the outside air heated by the first air heat exchanger and the second air heat exchanger, and a burner configured to burn off-gas of the solid oxide electrolyzer cell and anode off-gas of the stack;
- and
- a carbon capture system (CCS) configured to capture carbon dioxide from off-gas of the burner heat-exchanged in at least one of the reformer and the first air heat exchanger.
