Constrained by the land factor, the Taiwan Energy Bureau released the “ Photovoltaic Two-Year Promotion Plan ” on September 8, 2016 to promote the Floating Photovoltaic (FPV) industry. After that, the Agondian Reservoir FPV became the first successful commercial project. In this paper, the authors proposed a synthesis approach based on the exceedance probability approach to conduct the FPV reliability analysis. The case analysis results show that this paper ’ s proposal is feasible. The plan ’ s implementation will obtain the effect of CO 2 emission reduction of approximately 1,920 kt (kilo tons) in 20 years. The presented methodology may help evaluate the power supply reliability, reduce failures of FPV systems that have been installed or will install, and assist in extending the FPV system to areas with insufficient power but water bodies.","PeriodicalId":17318,"journal":{"name":"Journal of The Japan Institute of Energy","volume":"28 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83378048","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}

Lower concentration of melatonin was effective for growth promotion by improving stress tolerance while higher concentration of melatonin exhibited growth inhibition.

Briefly, the raw material was soaked in solutions of each chemical agent with ratio of 1:2 by weight for different times (1, 6, 12, and 24 h) and then carbonized at 500 ° C for 1 h. The obtained activated carbons were characterized for their surface area and porosity by nitrogen gas adsorption at ˗ 196 ° C. The highest surface area of 728 m 2 /g and total pore volume of 0.48 cm 3 /g were obtained from chrysanthemum activated with ZnCl 2 for a soaking time of 24 h. The activated carbon with the highest surface area was then characterized for other physicochemical properties and used for the adsorption of methylene blue (MB). The effects of contact time and initial MB concentration were investigated in batch mode. The equilibrium adsorption time was 60 min and the adsorption data followed the pseudo-second order kinetics. The adsorption isotherm was best described by the Langmuir model. The maximum monolayer adsorption capacity of activated carbon prepared from chrysanthemum for MB was 491.0 mg/g, which is higher than activated carbons prepared from other biomasses using chemical activation. Therefore, chrysanthemum-based activated carbon could be used as alternative adsorbent for MB adsorption from waste effluents.","PeriodicalId":17318,"journal":{"name":"Journal of The Japan Institute of Energy","volume":"28 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86529867","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}
