Abstract
EROI is an indicator to analyse energy productivity of a resource. EROI of Sirri operation unit is assessed in two different levels. Direct energy consumption and total associated gas are used in first and second level respectively. Two important aspects of the present research are considering environmental externalities and estimation of EROI related to outputs of multi-production systems. Also a model is introduced to identify relationship between oil price and EROI. Energy Abatement Cost is used to include environmental externalities to EROI. Thre benchmarks – price, energy and exergy content and exergy cost – are considered as a basis to for estimating EROI. Using LCA for taking into...
An Energy Sharing Model among Smart Energy Hubs Based on Blockchain Concept
, M.Sc. Thesis Sharif University of Technology ; Ranjbar, Ali Mohammad (Supervisor) ; Sheikhi, Aras (Supervisor)
Abstract
In the light of rapid advancement in renewable energy technologies, they become an appropriate way to supply energy demands with lower costs. It also gives them the chance to earn money by selling surplus energy to other energy consumers. The coordination of different energy types and the ability of energy conversion, facilitates the rising of new energy prosumers called “Smart Energy Hub(SEH)”. This thesis proposes a model of energy trading among SEHs. The model consists of SEHs, energy utility grids, energy consumers and aggregator. In this model, aggregator aggregates between SEHs, energy consumers and utility grids in order to maximize its profit. Bilevel optimization problem has been...

Abstract
The present study compared different approaches to assessing the environmental cost-effectiveness of energy policy scenarios. As a case study, the megacity of Tehran in Iran was studied. A key policy challenge in this city is to curb high concentrations of PM2.5 and mitigate the associated adverse impacts. The results demonstrated that in the business as usual case, the spatially averaged primary and secondary PM2.5 concentration in Tehran will increase by 30% in the 2010–2030 period. Adopting certain planned policy scenarios and the corresponding pollutant concentration reductions in Tehran shows that although most of the emission comes from industrial activities around the city, the...
