All of these things are costs. The most significant of them are likely to be compressor maintenance and parts and replacement of electrodes for alkaline electrolyzers and membranes in proton exchange membrane electrolyzers. Regular maintenance may be one day per year,...

What periodic servicing do electrolyzers require? Does servicing require extended outages? What percentage of the time is industrial-scale electrolyzer equipment typically available?

Regular maintenance requirements are about one day per...

One of the challenges in the past with the process of electrolysis of water has been fouling of electrodes. Has this problem been solved with modern electrolyzers?

by admin | Mar 27, 2021 | Production

Today’s electrolyzers are expected to have a minimum of ten-year lifetime with routine maintenance. Fouling is primarily controlled by purifying feedstock water into the electrolyzer stack. Work continues to improve both membrane materials in PEM electrolyzers and...

How long is the service life of an industrial-scale electrolyzer?

by admin | Mar 27, 2021 | Production

Commercial electrolyzer technologies today have service hour lifetimes in the range of 60,000-90,000 hours with routine maintenance before needing major overhauls (e.g., PEM membranes). See: Future cost and performance of water electrolysis: An expert elicitation...
