There are an awful lot of different Electrolyzers already in the market. The different parts of the industry will need to come together and establish some standards and common definitions and measurements to allow the focus to return to technology, resolving the basics of the Electrolyzer and bring it into a robust Industrial solution on a higher level of automation and scale.
I have referred to several technical documents offered by the Hydrogen Council, the Hydrogen Europe, and specifically, a white paper by Dr. Philipp Lettenmeir of Siemens called “Efficiency- Electrolysis,” written in January 2019.
At their own admission, it has been three years since they (IEA) released its last Energy Technology Perspective (ETP) report. Although they argue they have been reflecting on the critical technology challenges, it is way overdue.
IEA will further follow up later this year with a flagship ETP 2020 publication later in the year to keep a tighter and more consistent focus on the role and need of innovation to accelerate clean energy transitions.
