Cumulative energy demand in LCA: the energy harvested approach [PDF]

International Journal of Life Cycle Assessment, 2015
Purpose: Environmental life cycle assessment (LCA) is today an important methodology to quantify the life cycle based environmental impacts of products, services or organisations. Since the very first LCA studies, the cumulative energy demand CED (also called ‘primary energy consumption’) has been one of the key indicators being addressed.

Cumulative energy demand for selected renewable energy technologies

International Journal of Life Cycle Assessment, 1999
Calculation of Cumulative Energy Demand (CED) of various energy systems and the computation of their Energy Yield Ratio (EYR) suggests that one single renewable energy technology cannot be said to be the best. Due to the difference in availability of renewable energy sources, their suitability varies from place to place.

Cumulative energy demand and environmental impact in sustainable machining of inconel superalloy

Journal of Cleaner Production, 2018
Abstract Compared to flood machining, dry machining has sustainable potentials by eliminating the consumption of pump energy and coolant in production. However, the consumption of tool material with high embodied energy is significant in dry machining due to fast tool wear. Nevertheless, the trade-off on cumulative energy demand is not understood yet

Technical Product-Service Systems: Analysis and reduction of the Cumulative Energy Demand

Journal of Cleaner Production, 2019
Abstract Technical Product-Service Systems (PSS) consist of technical products that are enhanced by life cycle-oriented services. PSS enable companies to fulfill individual customer requirements and to build long-term customer relationships. Besides their economic advantages, PSS are attributed to positive effects on ecological sustainability ...

Electrodialysis versus ion exchange: comparison of the cumulative energy demand by means of two applications

Journal of Membrane Science, 2004
Abstract The aim of the present paper is the comparison of electrodialysis (ED) and ion exchange (IE) with regard to their cumulative energy demand by means of two applications separating ions with significantly different molar weight. Data for the separation of sodium gluconate and for the desalination of whey are obtained from laboratory ...

Cumulative energy demand (CED) and cumulative CO2 emissions for products of the organic chemical industry [PDF]

Energy, 2003
This paper both presents and discusses the results of calculations on the Cumulative Energy Demand (CED) and the related Cumulative CO2 emissions (CCO2) for products of the organic chemical industry. The entire process chain is studied, starting with the extraction of resources and ending with the saleable material (cradle-to-factory gate).

Harmonising the cumulative energy demand of renewable hydrogen for robust comparative life-cycle studies

Journal of Cleaner Production, 2018
Abstract A significant number of case studies evaluating hydrogen through the Life Cycle Assessment (LCA) methodology are available in the scientific literature. However, inconsistencies in their methodological frameworks lead to potential misinterpretation concerns when it comes to comparing LCA results. In order to mitigate this risk, harmonisation
