Scanning electron micrographs revealed the top view of microalgae and ash pellet with carbon coated specimens at low voltage (5.0 kV) through the secondary electron image detector. Elemental analysis revealed all the major and minor constituents of this microalgae species and its� ash in terms of dry weight (%) and atomic weight (%). Thermogravimetric analysis was conducted at heating rate, 10 �C/min and this experimental results determined moisture content, volatile matter, ash content and fixed carbon of the sample with 4.5%, 35%, 39.5% and 21%, respectively. Microalgae powder blended with bituminous coal by 75%, 50% and 25% measured calorific value 14.07 MJ/kg, 19.88 MJ/kg and 26.42 MJ/kg, respectively. Microalgae (75%) -coal (25%) blend showed excellent amount of energy content, 24.59 MJ/kg. Microalgae blended with coal unveiled an outstanding outcome with elevation of the volatile matter and drop of the ash content. Optimization of microalgae-coal blend in large-scale application can initiate bright future in renewable energy exploration. � 2018 Elsevier Ltd Final 2023-05-29T07:27:18Z 2023-05-29T07:27:18Z 2019 Article 10.1016/j.renene.2018.07.082 2-s2.0-85053115715 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85053115715&doi=10.1016%2fj.renene.2018.07.082&partnerID=40&md5=fea4ea6a35cf3226aafc43ee84633047 https://irepository.uniten.edu.my/handle/123456789/24803 131 617 624 Elsevier Ltd Scopus
