Hydrogen has nice promise as a low-emission gasoline supply. It burns clear, producing solely water as a by-product, and when it’s produced by means of electrolysis by splitting water into hydrogen and oxygen, your entire life cycle might be very environmentally pleasant.
However the usage of hydrogen has by no means reached its potential as a renewable gasoline, principally as a result of its manufacturing course of drives up the fee. Most hydrogen immediately continues to be produced as a by-product of fossil-fuel refinement—utilizing methane with carbon monoxide as a by-product. In the meantime, the hydrogen produced by electrolysis represents lower than 1 p.c of all of the world’s hydrogen manufacturing. To ensure that hydrogen to be a viable supply of fresh power, the price of electrolysis must be a lot decrease.
Sharaf Alsharif, a researcher on the Oldenburger OFFIS Institute for Info Expertise in Oldenburg, Germany, believes digital twins may assist carry down the price of clear hydrogen manufacturing. Digital twins are computer-simulation packages that may observe and modify the operations of a bodily gadget in nice element. The shut monitoring of hydrogen electrolyzers that digital twins present may assist streamline the gadgets’ operation and produce down the price of electrolysis in consequence.
“Proper now, we are able to’t consider all of the use instances that make an electrolyzer environment friendly. However that’s the purpose—which you could…make it attainable with this digital twin.”

A technique digital twins may cut back the price of electrolysis is by monitoring the state of well being of electrolyzers. Digital twins can observe the operations of electrolyzer elements like electrodes, membranes, or pumps to see which components could also be more likely to fail and to proactively make suggestions for scheduling upkeep. Alsharif says such prediction upkeep capabilities may save operators many hours of manufacturing time when electrolyzers would in any other case be taken offline to allow unscheduled troubleshooting.
To encourage the adoption of digital twins for electrolysis, Alsharif and his colleagues at OFFIS introduced a software program structure—a form of architectural blueprint for constructing software program programs—for creating hydrogen electrolysis monitoring digital twins on the ETG Congress 2023 convention in Germany.
The researchers envisioned a future the place hydrogen electrolysis operators would have dashboards that monitor the efficiency of electrolyzers operating within the discipline. Digital twins would supply the dashboard knowledge by remotely monitoring electrolyzers and issuing alerts when anomalous habits is detected. And having a well-defined software program structure, Alsharif says, may assist operators extra simply construct digital twins for his or her hydrogen electrolysis programs.
Digital twins may also assist operators by having direct management over electrolyzers, Alsharif says. One helpful utility of direct management is adjusting electrolyzers’ power consumption based mostly on the energy grid’s present power combine. When extra renewable sources of power are a part of the combination, digital twins can direct electrolyzers to ramp up manufacturing, due to this fact making the manufacturing of hydrogen extra inexperienced general. Manufacturing may also be decreased throughout utilization peaks when the value of power from the grid rises, which might decrease the price of hydrogen electrolysis manufacturing general.
Researchers stored these use instances in thoughts whereas they created a digital twin software program structure appropriate with any sort of hydrogen electrolyzer, Alsharif says. The structure needed to deal with necessities like bidirectional knowledge connections with electrolyzers, reside updates on the well being of electrolyzer elements, and maintenance-schedule suggestions.
They settled on a service-oriented structure for constructing digital twins for hydrogen electrolysis. A service-oriented structure consists of a central software program program that accepts requests from different smaller packages and “orchestrates” requests between all of the elements. The design gained over different architectural kinds due to its flexibility. New capabilities might be added to the digital twin simply within the type of new providers that merely plug into the central program.
“Proper now, we are able to’t consider all of the use instances that make an electrolyzer environment friendly,” Alsharif says. “However that’s the purpose—which you could truly apply any service and make it attainable with this digital twin.”
Service-oriented architectures are additionally quick sufficient to help the reside bidirectional knowledge connection wanted by electrolyzers. That’s in contrast to a microservice structure, for instance, which causes delays attributable to a better quantity of requests despatched between providers, Alsharif says. Operators who need to use digital twins to watch electrolyzers can observe this architectural blueprint when constructing the software program for his or her digital twins.
Future analysis, he says, may embrace utilizing digital twins to assist with the manufacturing technique of electrolyzers. To really scale up clear hydrogen manufacturing, the manufacturing of huge electrolyzers, which is at the moment a semi-manual course of, must scale up as nicely, Alsharif says.
“That’s the place the digital twins expertise comes into play—by supporting this entire course of, not solely the operation and upkeep of the electrolyzers, but in addition from the very starting of the manufacturing or the manufacturing course of,” he says.
