Summary: The International Maritime Organization has set regulations for reducing CO2 emissions, requiring a 40% reduction by 2030 and a 70% reduction by 2050 compared to 2008. It is estimated that 20% of the reduction can be achieved through optimizing speed and routes, while the remaining reduction requires the use of more sustainable technology. To achieve this, the authors propose retrofitting existing vessels with molten carbonate fuel cells (MCFCs) to produce additional energy and capture CO2 emissions. Simulation results using Aspen Plus and the homemade SIMFC code show promising results, and the impact of additional membrane systems and different recycle configurations for hydrogen recovery is also discussed.

Summary: This study investigates the influence of contact force on contact resistance between the current collector and the porous nickel layer of a fuel cell electrode through experimental and theoretical research. The main findings are: (i) the greater the force, the lower the contact resistance; (ii) above a certain level, the force applied to the electrode produces no significant change in contact resistance. An MCFC mathematical model is proposed to explain this phenomenon and provide a quantitative assessment of its impact on the performance of the entire fuel cell. The results demonstrate significant improvement in MCFC operating parameters when the compression force is increased to 40 N/cm2, but further force increase does not lead to appreciable improvement.

Summary: The review article summarized the recent advances in molten salt strategies for CO2 capture and conversion. MgO-based sorbents can efficiently capture CO2 through a reversible carbonation/calcination reaction, and the addition of alkali metal molten salt can greatly promote the CO2 uptake. Molten salts can also be used as activating agents and templates for the synthesis of porous carbons from biomass and plastics. In terms of CO2 conversion, electrochemical reduction in molten salts and the use of molten salts as catalysts can produce carbon materials and fuels.

Summary: Thermo-economic and environmental analyses were conducted on a hybrid power generation system, consisting of a biomass steam gasifier, an indirect heated air turbine unit, carbon dioxide separation using a molten carbonate fuel cell, waste heat recovery via organic Rankine cycle and steam Rankine cycle. Response surface methodology was used for multi-objective optimization to determine the operating state with highest exergy efficiency and lowest cost of electricity. The optimized system achieved an exergy efficiency of 47.46% and cost of electricity of 0.0993 $/kWh, generating 1.3 MW power with an energy efficiency of 54.5% and capturing 5052.58 tonnes of CO2 annually, resulting in an environmental benefit of $0.758 million. This study shows that the optimized hybrid power system outperforms conventional biomass-based plants in terms of exergy efficiency and cost of electricity.

Summary: Production of microalgae is a potential technology for capturing and recycling carbon dioxide from cement kiln emissions. This study investigated the selection of a suitable strain for efficient utilization of carbon dioxide and biomass generation. Results showed that a specific strain, Chlorella sorokiniana, exhibited the highest tolerance to cement kiln gas emissions and had similar biomass composition to laboratory grade CO2-grown algae. However, there was accumulation of heavy metals during growth, which highlights the need for careful monitoring and consideration of potential applications of the cultivated biomass.

Summary: The transition to net-zero emission energy systems creates synergistic opportunities across sectors. For example, utilizing by-product oxygen from water electrolysis in fuel hydrogen production can reduce the cost of carbon capture and storage in cement making. A techno-economic assessment was conducted to evaluate the production of clinker using oxy-combustion coupled to carbon capture and storage. The results showed an increase in thermal energy demand and electricity demand for oxy-combustion, but a lower cost of clinker production compared to the reference case without CCS.

Summary: This study calculates the global warming potential of biogenic carbon dioxide emissions (GWP(bCO2)) associated with redirecting residual biomass to bioenergy use. Comparing the decay of annual biogenic carbon pulses over 100 years, bioenergy use increases atmospheric CO2 load and results in different GWP(bCO2) values depending on the type of biomass. The study highlights the environmental benefits of using fast-decomposing agricultural residues as feedstock for bioenergy production.
