Electrolysis¶

Fields¶

The techno-economic data is distinguished across the following additional fields.

Subtechnologies¶

• AEL: Alkaline electrolysis
• PEM: Proton-exchange membrane electrolysis
• SOEC: High-temperature solid-oxide electrolysis

Size¶

Mainly CAPEX but also other parameters crucially depend on the size of an electrolysis plant. The size can be added as a non-coded field. For some sources, this may not be reported and hence set to N/S (not specified).

Aggregated parameters¶

All data added to the POSTED database is aggregated automatically using the POSTED framework. The result yields the following parameters:

CAPEX¶

The figure below gives an overview of CAPEX values reported by different sources across times, subtechnology (Alkaline, PEM, Solid Oxide), and plant size.

Raw data¶

The table below contains the raw data contained in the public POSTED database. This data has not be automatically normalised or harmonised in any way. You can also find this data in the GitHub repo in this file: posted/database/tedfs/Tech/Electrolysis.csv
