Production of these cryogenic fluids is an energy intensive process. Chilldown of the system prior to its operation is inevitable for the safe and manageable performance. This is accompanied with a large amount of cryogenic fluid loss that increases with the increase in chilldown time taken. This process, if done poorly, will cause wastage of cryogen which requires a lot of energy to produce. Therefore, saving cryogen in chilldown can save energy. In this study, effect of geometry and fluid flow pattern on chilldown characteristics of transfer lines has been investigated into. Comparative experimental study was conducted on straight and helically coiled transfer lines with 3 different orientation namely, horizontal, vertically upward and downward under continuous flow. It was found that helical coils could be chilled down faster. The comparison of chilldown time with continuous flow in straight and helically coiled tube was conducted using CFD simulation where, the pulsed flow pattern was identified to be more efficient for higher time period.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"128 1","pages":"220-224"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82598602","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 implementation of micro grid systems for dedicated areas will be one solution to deal with the electrical energy availability problem especially in some remote communities where located far from the main grid such as underdeveloped areas, remote island as well as some outer islands. Considering this problem, Indonesian government has launched Pre-electrification Program in year 2017. The main goal of this program is to increase the electrification ratio by providing Energy Saving Solar Lamps (Lampu Tenaga Surya Hemat Energi – LTSHE). To endorse this program, a study and design of solar-based energy saving lamp is presented in this paper. The special purpose of this study is to develop LTSHE prototype as part of contribution to national electrification ratio fulfilment program and to support government activity related to small grid development by utilizing the proper design and size for a more reliable solution. The long-term goal and objective to be achieved are the fulfilment of primary energy by utilizing new renewable energy resources by 23% by 2025. This paper will also show that the government equipment specification of LTSHE is not applicable in some area with low solar irradiance in Indonesia, in this case, North Sumatera region.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"35 1","pages":"98-102"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77278614","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}

Renewable energy mini-grids are increasingly regarded as viable approaches to rural electrification. However, despite this potential, mini-grid energy service companies (ESCOs) in sub-Saharan Africa are faced with financing challenges, which emanate from unattractive risk-return profiles. Thus, this study sought to explore the potential of strategic investment as a way to attract additional funding to mini-grid ESCOs in order to advance the sector to a commercially viable phase. Indepth interviews were conducted with executive managers of mini-grid ESCOs and potential strategic investors. It was found that there is a need for strategic investment among mini-grid ESCOs. The study contributes to the evolving best practices of viable mini-grid business models, by recommending that mini-grid ESCOs should build competencies in customer relationship management, rural distribution practices and the extrapolation of rural households’ uptake of electricity and electricity dependent products and services from consumption data to commercial applications. Indeed, the study has shown that potential strategic investors attach value to these focus areas, with the implication that when mini-grid ESCOs can demonstrate these competencies successfully, the probability of successfully attracting strategic investment would increase. Considering these implications, the study offers a contribution to the development of pathways to attract investment to mini-grid ESCOs, the achievement of which will facilitate energy leapfrogging in the region.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"9 1","pages":"29-37"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76485091","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}

For this purpose, it was designed and constructed experimental set up with a prototype of flat plate solar collector with phase change material containers located under the absorber plate. Experimental tests were performed under outdoor conditions with and without phase change material, from 7:00 am to 7:00 pm. Temperatures of the ambient, absorber plate, water outlet, water inlet and PCM are compared with the behavior of solar radiation for 3 different cases. It was observed that using PCM reduce the fluctuation in water outlet temperature and absorber plate temperature due to solar radiation reduction, in fact, temperature variations were 55 % and 49.8 % lower compared with test without PCM, respectively. In order to compare results under different solar radiation conditions with and without PCM, conclusions were obtained by comparing these temperatures in proportion to the reduction of solar radiation.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"218 1","pages":"83-87"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85540274","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}

Section 62 of the National Land Code 1965 has stipulated that the State Authority has the power to reserve state land for any public purposes, including river reserves. Nonetheless, its criteria are determined by the width of the reserved land and are highlighted only for bank stabilization, biodiversity, and water quality purposes. Additionally, some studies have proven that vegetated urban riparian promotes thermal reduction, in comparison to those covered with mere hard surfaces. As such, this study looked into the effect of urban riparian structure upon local thermal environment so as to gain an overview of the possible form of heat transfer occurrence. With that, this study investigated two varied formations of river reserve located side-by-side, which is bound by the same river in Johor, Malaysia. Despite of the low-albedo materials, the developed river reserve displayed somewhat lower air temperature, when compared to undeveloped river reserve area. In addition, ambient air temperature and relative humidity of both the investigated sites were linked to some factors, such as shading and wind movement. In fact, vegetation vertical clearance that caused wind flow obstruction could have been influential as well. Therefore, the effect of vegetation structure has to be comprehensively understood. With that, it is possible to determine the multiple functions of a river reserve, especially after implementing several passive cooling strategies within the area.","PeriodicalId":6536,"journal":{"name":"2018 2nd International Conference on Green Energy and Applications (ICGEA)","volume":"2011 1","pages":"45-50"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87824317","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}
