Owing　to　considerable　energy　constraints　and　global　warming　phenomenon,　to　find　alternative　sources　of　renewable　and　affordable　energy　has　become　a　highly　prerequisite　in　this　current　era.　Use　of　sustainable　technologies　in　this　regard　for　renewable　fuel　retention　applications　has　become　more　beneficial　in　encouraging　the　broad　usage　of　clean　energy.　Conjugated　microporous　polymers　(CMPs)　are　a　distinct　family　of　composites,　that　merge　extensive　the　p-conjugation　with　microporous　structure.　The　CMPs　have　been　recognized　as　an　essential　subclass　of　porous　composites,　ever　since　their　development　in　2007.　The　CMPs　have　been　developed　with　a　number　of　distinct　configurations　and　characteristics,　which　allows　for　the　versatility　of　conjugated　framework　cellular　implementations　and　mesoporous　structure.　The　exploration　of　CMPs　in　sustainable　fuel　devices　is　crucial　for　the　development　of　CMP-based　composites　and　their　use　in　sustainability　and　environmental　design.　Numerous　network　developing　processes　and　synthesized　building　components　provide　a　huge　heterogeneity　of　CMPs　with　various　characteristics　and　design　patterns.　As　a　consequence,　CMPs　have　been　employed　here　for　cathode/anode　materials　for　lithium　ion　batteries　(LIBs),　sodium/potassium　LIBs,　supercapacitors,　fuel　cell　electrode　for　solar　cell,　hydrogen　storage　materials,　photocatalytic　hydrogen　and　oxygen　production　reaction　(HER,　OER),　photocatalytic　CO2　reduction　and　so　on.　Due　to　the　large　surface　areas　of　these　composites,　the　distinctive　charge　storage　mechanisms　found　in　CMPs　are　explored,　and　a　synopsis　of　how　CMPs　might　facilitate　ultrafast　in　desirable　variety　is　presented.　In　addition,　an　evaluation　between　CMPs　and　linear　polymers　is　presented,　which　provides　further　assistance　for　the　synthesis　of　active　materials.　The　most　significant　shortcomings　experienced　by　CMPs　in　the　domains　of　energy　production　have　been　evaluated,　and　potential　strategies,　synthetic　process　with　reactions,　physiochemical　properties　along　with　morphology　have　been　demonstrated.　Thus,　this　review　is　intended　to　be　an　entertaining　and　motivating　study　in　the　scientific　community　of　the　energy　storage　experts.
