Electrolyser selection
Comparing alkaline and membrane systems against the power profile, purity and footprint.
It follows the power profile. Alkaline systems are established and cheaper but respond more slowly to variable input. Proton exchange membrane systems handle variability better and start faster, at higher cost and higher water purity requirement. The variability of your supply decides which is right.
What this includes
- Technology comparison against the actual power profile
- Efficiency and degradation over the term
- Water purity requirement per technology
- Footprint and balance of plant
- Stack replacement schedule and cost
- Supplier evaluation and warranty review
- What you receiveOutput
- Technology recommendation with efficiency, footprint and cost basis
- When you need itTiming
- After the power profile is known.
Selecting on capital cost. A slow responding system on a variable renewable supply spends much of its life idle, which never appears in the quotation.
