DATA-SPECIFIC INFORMATION:

1. Specialized formats or other abbreviations used: 

Abbreviations:
LHV: Lower heating value of Combustion
HHV: Higher heating value of Combustion

Values:
Scenario_Year: The reference scenario year, e.g where authors are making a projection for 2040, this will be "2040".
Temp: This is a broad category for high temperature (SOEC) or low temperature (AEC, PEMEC) electrolysis methods.
Cost_eu_KW: The cost in Euro per Killowatt 
Efficiency_LHV: The efficiency of electrolysis assuming the LHV
Ref_year_min: The oldest (lowest) cost data used in a paper, if a paper from 2020 cites a reference from 2014 for cost data, this will be "2014"
Pub_Year: Publication year of paper
Plant_size_scale(MW): The size of the electrolyser stack (see below) based on Megawatts. 
p(Kpa): Pressure of electrolyser output where data was available
Heating.Value: Either LHV or HHV to take into account in the off chance the latter was used
Capacity_Function(%): Reported electrolyser capacity factor in percentage
Type: Type of the literature source
Method_Lit: A categorical variable to designate the literature review methods of a source, and discern the class of source.
Eur_Factor: Currency factor index calculation year (Based on Euro)
Category: Overall group assosciation of data entry 
Bracket: Scenario year bracket of source


Sundry information: 
Plant Sizes*
-Small: 1-4 MW
-Medium: 5-19MW
-Large: => 20MW

*'Plant size' for sources which are reviews that consider value ranges are taken as the mean plant size. 

Method_Lit naming convention:
Roughly based on a naming convention from Glenk & Reichelstein (2019)

Original_Review_Multiple_Sources: A peer reviewed journal article based on a comprehensive literature review with multiple academic and industry sources
Original_Analysis_w_Industry_Sources: An analysis or grey literature, usually from industry or other independant sources, with industry sources
Secondary_Source: A value from a peer reviewed article which cites another source

General:
-Generally system lifetime is ~20 years 
-WACC of 5-6% over sources
-Scenarios are always base-case unless otherwise stated
