“…It was assumed that the larger proportion of impurities (primarily N 2 ) was acceptable for transport and storage conditions and that a higher compression duty resulting from these lower boiling point gases was considered acceptable. However, some sources recommend CO 2 purities >96 mol%, for which a purification unit may be required [56]. The overall power consumption will be minimally affected, with a marginal increase of specific emissions (due to purging in the purification unit), although the addition of cryogenic exchangers and vessels will lead to a higher overall plant cost [57].…”

The hydrogen economy has received resurging interest in recent years, as more countries commit to net-zero CO2 emissions around the mid-century. “Blue” hydrogen from natural gas with CO2 capture and storage (CCS) is one promising sustainable hydrogen supply option. Although conventional CO2 capture imposes a large energy penalty, advanced process concepts using the chemical looping principle can produce blue hydrogen at efficiencies even exceeding the conventional steam methane reforming (SMR) process without CCS. One such configuration is gas switching reforming (GSR), which uses a Ni-based oxygen carrier material to catalyze the SMR reaction and efficiently supply the required process heat by combusting an off-gas fuel with integrated CO2 capture. The present study investigates the potential of advanced La-Fe-based oxygen carrier materials to further increase this advantage using a gas switching partial oxidation (GSPOX) process. These materials can overcome the equilibrium limitations facing conventional catalytic SMR and achieve direct hydrogen production using a water-splitting reaction. Results showed that the GSPOX process can achieve mild efficiency improvements relative to GSR in the range of 0.6–4.1%-points, with the upper bound only achievable by large power and H2 co-production plants employing a highly efficient power cycle. These performance gains and the avoidance of toxicity challenges posed by Ni-based oxygen carriers create a solid case for the further development of these advanced materials. If successful, results from this work indicate that GSPOX blue hydrogen plants can outperform an SMR benchmark with conventional CO2 capture by more than 10%-points, both in terms of efficiency and CO2 avoidance.

“…IGCC power generation is still at a conceptual stage in China (Ku et al 2018) but it may be possible to move toward a practical demonstration of IGFCs in the next decade, with current progress in fuel cell technology. IGFC systems based on MCFCs and SOFCs have been demonstrated (Campanari et al 2016;Samanta and Ghosh 2017;Wolfersdorf and Meyer 2017;Mu et al 2018;Slater et al 2018), it is clear that the fuel cell integrated CO 2 capture process is a promising route, and will be more effective if fuel cell technology can be commercialized (Wang et al 2020). The fuel cell, as a key power generation device, has the advantages of being very efficient and environmentally friendly.…”

The use of high-temperature fuel cells as a power technology can improve the efficiency of electricity generation and achieve near-zero emissions of carbon dioxide. This work explores the performance of a 10 kW high-temperature molten carbonate fuel cell. The key materials of a single cell were characterized and analyzed using X-ray diffraction and scanning electron microscopy. The results show that the pore size of the key electrode material is 6.5 µm and the matrix material is α-LiAlO2. Experimentally, the open circuit voltage of the single cell was found to be 1.23 V. The current density was greater than 100 mA/cm2 at an operating voltage of 0.7 V. The 10 kW fuel cell stack comprised 80 single fuel cells with a total area of 2000 cm2 and achieved an open circuit voltage of greater than 85 V. The fuel cell stack power and current density could reach 11.7 kW and 104.5 mA/cm2 at an operating voltage of 56 V. The influence and long-term stable operation of the stack were also analyzed and discussed. The successful operation of a 10 kW high-temperature fuel cell promotes the large-scale use of fuel cells and provides a research basis for future investigations of fuel cell capacity enhancement and distributed generation in China.
