“…Among a range of fuel cell types, using solid oxide fuel cells (SOFCs) for power generation and simultaneously CO 2 capture is a prospective and attractive approach. SOFCs are low-emission, modular, fuel-flexible, and high electrical efficiency devices with the capability of converting diverse fuels into heat and power (Thattai et al, 2017). In the SOFC unit, the electrochemical fuel oxidation involves the automatic separation of nitrogen from oxygen, and the anode output is passed through an oxyfuel combustion system in which the unused fuel (since fuel utilization is not 100% in SOFCs) is burned with pure oxygen (with the oxygen taken from a separate tank, and possibly coming from electrolysers), thereby producing a CO 2 -enriched gas.…”

Negative emission technologies have recently received increasing attention due to climate change and global warming. One among them is bioenergy with carbon capture and storage (BECCS), but the capture process is very energy intensive. Here, a novel pathway is introduced, based on second-generation biofuels followed by carbon circulation in an indefinitely closed chain, effectively resulting in a sink. Instead of using an energy-intensive conventional CCS process, the application of an on-board solid oxide fuel cell (SOFC) running on biofuels in an electric vehicle (FCEV) could result in negative emissions by capturing a concentrated stream of CO2, which is readily stored in a second tank. A CO2 recovery system at the fuel station then takes the CO2 from the tank to be transported to storage locations or to be used for local applications such as CO2-based concrete curing and synthesis of e-fuels. Incorporating CO2 utilization technologies into the FCEVs-SOFC system can close the carbon loop, achieving carbon neutrality through feeding the CO2 in a reverse-logistic to a methanol plant. The methanol produced is also used in SOFCs, leading to an infinite repetition of this carbon cycle till a saturation stage is reached. It is determined this pathway will reach typical Cradle-to-Grave negative emissions of 0.515 ton CO2 per vehicle, and total negative CO2 emission of 138 Mt for all passenger cars in the EU is potentially achievable. All steps comprise known technologies with medium to high technology readiness level (TRL) levels, so principally this system can readily be applied in the mid-term.

“…1 FCs can operate at different temperatures; solid oxide fuel cell (SOFC), phosphoric acid fuel cell (PAFC), molten carbonate fuel cell (MCFC), direct methanol fuel cell (DMFC), alkaline fuel cell (AFC), and polymer electrolyte membrane fuel cell (PEMFC). 2 The operating temperatures of the first and second types range from 600 to 1000 C ( [3][4][5] ). Whereas, the AFC, DMFC, PAFC, and PEMFC operate at temperature ranges of less than 80, 90 to 120, 150 to 200, and 50 to 100 C, respectively.…”

SUMMARY In this article, the application of a hybrid phosphoric acid fuel cell and organic Rankine cycle (PAFC/ORC) system was thermo‐economically investigated for sulfuric acid production in Sarcheshmeh copper complex (SCC); the second largest copper deposit worldwide. The electricity that is produced by the system is consumed by electrolyzer to produce the hydrogen and sulfuric acid. Two scenarios were considered for applying the PAFC thermal energy as thermal source of the ORC to produce further power. The performance of the system was investigated considering various important parameters such as organic fluid type, PAFC current density (IPAFC), fuel & air consumption factors as well as the ORC turbine inlet pressure (Pi, ORC). The unit cost of sulfuric acid and the hybrid system simple payback period were obtained as 0.0215$/kg and 3.65 years, respectively.

In combined cycle gas turbines, most of the energy loss is usually due to the high temperature of the exhaust gases. Different heat recuperation methods are used. In this study, a novel direct method for heat recovery is investigated. Confidence in the results is established by accounting for all the losses and simulation errors while comparing with the conventional cycle. Aspen HYSYS and MATLAB are the simulation tools used. The General Electric (GE) 9HA.02 combined cycle is taken as a base case. Five gases, air, argon, hydrogen, nitrogen, and carbon dioxide, are studied with the proposed modification. The efficiency maximization function is updated and the pressure and temperature ratios of individual Brayton and Rankine cycles are discussed. The combustor/heat exchanger is modified and simulated according to the known principles of heat and momentum transfer. The whole simulation algorithm is provided. Equation of state (EOS-PR) is used to calculate the properties at every discretized step (for H2, critical properties are modified/HYSYS inbuilt feature). Different gases are analyzed according to their property profiles over the whole cycle. The effect of fluid properties on efficiency is discussed as a guideline for any tailored fluid.
