Energy, environmental and economic evaluations of a CCHP system driven by Stirling engine with helium and hydrogen as working gases

Optimal Operation Strategy of Multi-Energy Complementary Distributed CCHP System and its Application on Commercial Building

“…normally consists of prime movers (e.g., gas turbine, Stirling engine and fuel cell), renewable power generators (e.g., wind turbine and solar photovoltaic) and auxiliary equipment (e.g., organic Rankine cycle (ORC) and refrigeration equipment). Two beta type Stirling engines [1] were suggested in the CCHP system to analyze the energy flow of the absorption chiller by utilizing waste heat of the engine. In [2]- [4], the optimal planning and operation strategies of a CCHP system that includes renewable energy and other distributed generators were discussed to reduce the total cost and CO 2 emissions.…”

Energy, exergy, economic, and environmental (4E) analyses and optimization of a CCHP system with steam turbine

“…The power generated by the tri-generation system is achieved by one or more prime movers; for example, gas turbines, 1,2 combustion engines, 3,4 fuel cells, 5 and Stirling engines. 6,7 The steam turbine used in the Rankine cycle can be utilized in a tri-generation system. The Rankine cycle is similar to the organic Rankine cycle (ORC).…”

“…Due to greenhouse gas emissions and the issue of reduction in the amount of fossil fuels and global warming, the use of effective systems such as the tri‐generation system becomes even more important. The power generated by the tri‐generation system is achieved by one or more prime movers; for example, gas turbines, 1,2 combustion engines, 3,4 fuel cells, 5 and Stirling engines 6,7 . The steam turbine used in the Rankine cycle can be utilized in a tri‐generation system.…”

Improving the economic efficiency of vapor recovery units at hydrocarbon loading terminals

“…VRU has a very high capital cost. In addition to capital costs, operating costs are also allocated, which include: the cost of electricity consumed, maintenance and repair costs, as well as planned replacement of adsorbent or liquid nitrogen (depending on the technology used) (Chahartaghi and Sheykhi, 2019). In this case, it is quite risky to invest monetary assets in VRU implementation projects, as they can take a long time to pay off (more than 5 years).…”
