Cost analysis of energy conversion systems via a novel resource-based quantifier

摘要: Abstract The paper presents a new formalism for the costing of production chains, with special emphasis on energy conversion systems. From mathematical point view, this method can be described as standard Leontiev-type input-output technique, in formulation commonly adopted by most theories, including Thermoeconomics. Any complex chain decomposed into modules, to each one which mass and balances are applied. resulting flow diagram is then examined from an exergetic cost analysis performed. paradigm novel feature here: rather than monetary units, resource-based quantifier, called “extended exergy”, employed. It argued that both labour financial costs properly linked equivalent resource consumption through back-to-resource accounting procedure expresses total exergy required “generate” man-hour work or unit currency circulation. Environmental remediation similarly taken account computing cumulative expenditures achieve zero impact. argued, discussed basis example application cogeneration plant, Extended Exergy Accounting (EEA), substantial improvement respect current engineering economic techniques, shown EEA calculates real, “value” commodity (which not necessarily equal its cost) thus enabling Analysts Energy Planners perform more complete meaningful assessment Engineering Complex System. decisive advantage consists being entirely uniformly resource-based: respect, it owes some structural theory commodities, extends unavoidable dissipation productive chain, resource-oriented economics. must acknowledged well follows path originally proposed Szargut his “Cumulative Consumption” method, providing rational uniform treatment all non-externalities.
