Optimising green hydrogen production using system simulation
Using system simulation can help significantly to address the challenges of green hydrogen production and distribution
Patrice Montaland Siemens Digital Industries
I n the very near future, hydrogen will play a key role in decarbonising the transportation, energy and industry sectors. Hence, many countries have already established policies to support development of a hydrogen infrastructure, and more and more industry stakeholders are investing in hydrogen projects. Despite this, hydrogen will only really emerge if it can be produced and distributed efficiently and safely at a competitive cost.
the complete process of green hydrogen from production to distribution. As demonstrated in this article, system simulation makes it possible to build the digital twin and predict the performances of a system combining wind turbines, solar panels and a wave converter with an electrolyser and a hydrogen compression system. Using simulation makes it possible to quickly evaluate different system architectures, components sizing and control strategies to produce hydrogen and green energy with the best global efficiency, system reliability and return on investment (ROI).
