District energy systems have the potential to decrease the CO2 emissions linked to energy services (heating, hot water, cooling and electricity), thanks to the implementation of large polygeneration energy conversion technologies, connected to a group of buildings over a network. To transfer the energy from the large polygeneration energy conversion technologies to the users, conventional distr...

Given the current scenario of increasing environmental problems associated with need for rapid energy transition, this article aimed to investigate implementation Cynara cardunculus L. (cardoon), a plant high performance, as source resources. This study presented thLife Cycle Assessment two production chains—for polygeneration power, heat, and cooling; produce biodiesel—fed cardoon seeds, in ad...

Reliable isolated energy systems are necessary for supplying energy to remote areas where grid extension is not feasible. It may also be required to harness renewable energy to reduce the use of conventional fuel that involves potentially high transportation cost and carbon emissions. Polygeneration systems are suitable for distributed energy supply in remote areas with the advantages of compac...

Full chain energy performance is applied to a hybrid combined cooling, heating and power (CCHP) system running with methanol and solar energy. Results show that the overall energy efficiencies of six different cases range from 40% to 50% in summer condition, and 38% to 47% in winter condition. Combined with the traditional methanol production process, the CCHP systems are not energy efficient c...

The residential sector plays an important role to mitigate climate change due its high energy consumption. Polygeneration systems are a suitable alternative enabling efficient use of natural resources with low environmental impact. However, their deployment depends, among other factors, on the economic cost and legal restrictions. This work analyses potential reduction greenhouse gases emission...

a preliminary design of a polygeneration system (combined cooling-heating-power plant with a desalination unit), is proposed for a tourist resort located on the spanish coast. the well-known trigenerationconcept is enhanced to the included production of desalted water, considering for the purpose three different options: reverse osmosis (rodp), multi-effect (medp) and a combination of rodp and ...

The optimal design of an energy polygeneration system that converts coal and biomass to electricity, liquid fuels (naphtha and diesel) and chemical products (methanol) with CO2 capture under different economic scenarios is investigated. In this system, syngas is produced by gasification of coal and/or biomass; purified by a cleaning process to remove particles, mercury, sulfur and carbon dioxid...
