This study examines a more sustainable energy generation system --- the\u003Cbr \/\u003E\r\ndistributed combined cooling, heating, and power integrated with renewable energy and energy storage system\u003Cbr \/\u003E\r\n(CCHP-RE-ESS). A parametric hybrid life cycle assessment framework approach is used to evaluate the\u003Cbr \/\u003E\r\nenvironmental, economic, and social impacts of the proposed distributed energy generation system. The rationale for\u003Cbr \/\u003E\r\na parametric LCA approach is that it extends conventional LCA, which is cases-specific and shows how impacts\u003Cbr \/\u003E\r\nchange with different input factors such as ambient temperature, climate, and operation strategies. The impact results\u003Cbr \/\u003E\r\nintegrate with a multi-objective optimization method, Pareto front, to find the optimal environmental and economic\u003Cbr \/\u003E\r\nimpact trade-offs for different building energy demand scenarios. The parametric framework includes six\u003Cbr \/\u003E\r\ncommercially available trigeneration technologies: two for prime movers (microturbine and fuel cells), two for\u003Cbr \/\u003E\r\nrenewables (solar power and small wind turbine), and two for energy storage (lithium-ion battery and compressed air\u003Cbr \/\u003E\r\nenergy storage). The model is able to find the best combination of technologies and their corresponding sizes for\u003Cbr \/\u003E\r\ndifferent building demand profiles. After billions of simulations, the Microturbine-Solar PVs-Lithium ion Battery and\u003Cbr \/\u003E\r\nFuel Cells-Solar PVs-Lithium-ion Battery are two optimal distributed energy solutions. The simulation impact result\u003Cbr \/\u003E\r\nshows that the system can primarily reduce the environmental impact as compared to the conventional energy system.\u003Cbr \/\u003E\r\nHowever, the life cycle cost of CCHP-RE-ESS is higher than the traditional energy generation, especially for fuel\u003Cbr \/\u003E\r\ncell-based system.\u003Cbr \/\u003E\r\nFinally, the model evaluates the social cost and the current U.S. clean energy policy incentives impacts on the\u003Cbr \/\u003E\r\ndistributed CCHP-RE-ESS system. The model uses the Air Pollution Emission Experiments and Policy model to\u003Cbr \/\u003E\r\nevaluate the marginal damages emissions on a dollar per ton basis. Results show that the social cost of conventional\u003Cbr \/\u003E\r\nenergy is significantly higher than the distributed energy generation. Based on the simulation result, it is estimated\u003Cbr \/\u003E\r\nthat the installation of the distributed CCHP-RE-ESS can help avoid more than 50 billion dollars of social cost per\u003Cbr \/\u003E\r\nyear for commercial buildings in U.S. Besides, the model study the cost-saving potential of current U.S. clean energy\u003Cbr \/\u003E\r\npolicy incentives, including federal tax credit, low-interest loan, and Modified Accelerated Cost Recovery System\u003Cbr \/\u003E\r\n(MACRS). The tax credit and MACRS can primarily reduce the cost of distributed energy by average 50%, while\u003Cbr \/\u003E\r\nlow-interest loan increases the cost by average 30%. In some scenarios, the after-policy life cycle cost of distributed\u003Cbr \/\u003E\r\nenergy generation is competitive compared to conventional power, but for most situations, the life cycle cost is still\u003Cbr \/\u003E\r\nhigher as compared to conventional power. Future work includes: (1) integrate more trigeneration technologies (e.g.,\u003Cbr \/\u003E\r\nthermal storage), (2) adopting hybrid operation strategy that switching between following electrical load and\u003Cbr \/\u003E\r\nfollowing the thermal load, and (3) customized building design for more realistic building energy demand profile.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Parametric Life Cycle Assessment of Combined Cooling, Heating, and Power Integrated with Renewable Energy and Energy Storage"}],"uid":"27707","created_gmt":"2019-11-27 16:56:02","changed_gmt":"2019-11-27 16:56:02","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-12-13T12:00:00-05:00","event_time_end":"2019-12-13T14:00:00-05:00","event_time_end_last":"2019-12-13T14:00:00-05:00","gmt_time_start":"2019-12-13 17:00:00","gmt_time_end":"2019-12-13 19:00:00","gmt_time_end_last":"2019-12-13 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
