However, this requires a detailed demand model, which is often not available in the early planning stages. To address this need, this paper proposes a novel methodology for building a demand model using available information, including types of zones/sectors present on-site, historical energy consumption of those sectors at a national level, and energy consumption studies on floor-stock basis (i.e., floor area). We apply this approach in a case study energizing the proposed Aerotropolis Core Precinct (ACP) within the wider Aerotropolis site to be constructed in Western Sydney, New South Wales, Australia. The model also looks at supplying this demand, and the corresponding associated emissions, for the years 2025, 2035 and 2050 – in line with Australia’s Net Zero-time horizon. Results show that ACP demand increases from 368 GWh in 2025 to 1,233 GWh in 2035 then 1,444 GWh in 2050, as is expected moving from partial to full operation and accounting for temperature-dependent demand fluctuations. Electrical demand is 62% of total demand, while thermal is 38%. Generated supply is estimated to increase from 221 MW (2025) to 866 MW (2035) and 1,077 MW (2050), accounting for capacity factors. Emissions associated with that demand will change from 185 ktCO<sub>2</sub>eq to 229 ktCO<sub>2</sub>eq then decrease to 201 ktCO<sub>2</sub>eq due to an increasingly “greener” technology mix predicted (i.e., no use of coal due to shutdowns of coal-fired power plants, and very little gas use by 2050). These methods and estimates provide a decision-making basis for government policy-making, energy planning, and technology supply for greenfield sites, as well as provide a platform to invite stakeholder engagement.</p></div>","PeriodicalId":34738,"journal":{"name":"Smart Energy","volume":"12 ","pages":"Article 100117"},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48772133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis shows that present PE estimation lacks scientifically justifiable grounds to compare any parameters that depend on it. For example, present EROI calculation is unsuitable for technology-to-technology or system-to-system or system-to-technology comparisons because of the variation of primary energy quality (PEQ) with a resource-technology combination. The main cause of PEQ discrepancy is the absence of reference energy quality that facilitates proper comparison and interconversion. This study shows that standardising PEQ enables a scientifically meaningful quantification of PE and a justifiable comparison of EROI as well as other relevant indicators depending on it. Electricity emerges as the best option for solving the differences in PEQ in the short-term.

Given the urgent need for cost-effective solutions in response to the climate crisis, it is crucial to analyze the feasibility of retrofitting existing power plants to operate carbon-neutral. The aim of this work is to provide a techno-economic analysis for the conversion of a conventional cogeneration system to run on locally produced hydrogen. Building on the energy consumption of the paper mill, the operation of a hydrogen-fuelled gas turbine is modelled in detail. Based on these results, a multi-energy system model for the production of green fuel is presented, considering production via solar-powered PEM electrolyzers, storage in tanks and final use in the gas turbine. An optimal configuration for the system is defined, leading to the definition of a solution that ensures a cost of 6.41 /kg for the production of green hydrogen. Finally, a sensitivity analysis highlights the close dependence of the economic profitability of the Power-to-X system on the natural gas price. The results indicate that although positive performance is achieved, the cost of investment remains still prohibitive for systems of this size, and the high initial capital expenditure needs to be supported by incentive policies that facilitate the adoption of hydrogen in industrial applications making it competitive in the short term.</p></div>","PeriodicalId":34738,"journal":{"name":"Smart Energy","volume":"11 ","pages":"Article 100114"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41425818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mainly during 2022 and 2023, there was an intensive process to launch a recast Energy Performance of Buildings Directive, to assure favourable policy framework conditions. In this context, the current paper addresses the following question: How does the consideration of staged renovation change the view of cost-optimal building standards and related building renovation assessments? For that, this paper analyses the staged building renovation and the time perspective when they are performed related to cost-optimal building standards. The workflow relies on the following methods: (1) cost-optimal methodology and global costs calculation and (2) mixed-integer optimisation to derive optimum timing of staged renovation under household budget constraints. The analysis consists of a country comparison (Spain, Germany and Sweden) and an evaluation of different energy efficiency measures. The main conclusion is that in staged renovations, the cost-optimal variant was in many cases the climate-optimal one when using the metric cumulative CO<sub>2</sub> emission. Although the metric “cumulative CO2 emissions” is not suggested by the EPBD yet, this metric represents the depth and time perspective of renovation activities. Therefore, in order to speed up building stock decarbonisation cost-optimal methods alone are not sufficient to increase buildings' energy efficiency and climate neutrality in a fast way. In addition to that, considering households’ budget as optimisation variable can be an effective to assess the time when renovation activities are performed.</p></div>","PeriodicalId":34738,"journal":{"name":"Smart Energy","volume":"11 ","pages":"Article 100110"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46613290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the variability of WWS electricity, producing green hydrogen intermittently, rather than continuously, thus with electrolyzer use factors significantly below unity (0.2–0.65), may reduce overall energy costs with 100% WWS.
