Electrolysis¶

This dataset contains techno-economic data on a water electrolysis for producing electrolytic hydrogen.

Fields¶

The techno-economic data is distinguished across the following 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 in this dataset can be aggregated via the NOSLAG workflow, which yields the following parameters:

CAPEX¶

The figure below gives an overview of CAPEX values reported by different sources over time and across subtechnologies and plant sizes.

Electricity demand¶

The figure below gives an overview of electricity demand values reported by different sources over time and across subtechnologies.

Raw data¶

The table below contains the raw data contained in this dataset. The raw data has not be normalised or harmonised in any way and should closely resemble the data as it is reported by the respective sources. You can also find this data in the GitHub repo in this file: posted/database/tedfs/Tech/Electrolysis.csv
