Editing Energy carrier (section)

==Definition according to ISO 13600==
According to ISO 13600, an '''energy carrier''' is either a substance or a phenomenon that can be used to produce mechanical work or heat or to operate chemical or physical processes.<ref>[https://www.iso.org/obp/ui/#iso:std:iso:13600:ed-1:v1:en ISO 13600:1997(en) Technical energy systems — Basic concepts]</ref> It is any system or substance that contains [[energy]] for conversion as usable energy later or somewhere else. This could be converted for use in, for example, an appliance or vehicle. Such carriers include [[spring (device)|springs]], [[electrical batteries]], [[capacitors]], [[pressurized air]], [[dammed water]], [[hydrogen]], [[petroleum]], [[coal]], [[fuel wood|wood]], and [[natural gas]].

ISO 13600 series (ISO 13600, ISO 13601, and [[ISO 13602]]) are intended to be used as tools to define, describe, analyse and compare technical energy systems (TES) at micro and macro levels:<ref>[https://www.iso.org/obp/ui/#iso:std:iso:13602:-1:en  ISO 13602-1:2002(en) Technical energy systems — Methods for analysis — Part 1: General]</ref>

*ISO 13600 (''Technical energy systems — Basic concepts'') covers basic definitions and terms needed to define and describe TESs in general and TESs of energyware supply and demand sectors in particular.
*ISO 13601 (''Technical energy systems — Structure for analysis — [[Energyware]] supply and demand sectors'') covers structures that shall be used to describe and analyse sub-sectors at the macro level of energyware supply and demand
*[[ISO 13602]] (all parts) facilitates the description and analysis of any technical energy systems.
