The NEWP Lab congratulates first author Mahdi Sharifzadeh, second author Nathanial Cooper, and third and fourth authors Hans van’t Noordende and Nilay Shah on their new publication in the International Journal of Hydrogen Energy, “Operational strategies and integrated design for producing green hydrogen from wind electricity.” [1]

Highlights include:

• The main challenge of wind power utilization is its intermittent availability.
• Flexible operation of alkaline and PEM electrolyser can improve LOCH.
• Near minimum load operation and shutdown strategies have profound impacts on the economy of hydrogen generation.
• Battery integration reduces the levelized costs of hydrogen.

Where “[realizing] the potential of renewable hydrogen production requires flexible operation of electrolysis systems to integrate with intermittent power sources,” the integration of battery storage technologies stands to further enhance asset utilization [1]. In assessing operational strategies for alkaline and proton exchange membrane (PEM) wind-powered electrolysers, the optimization model this research develops offers fresh insight on the impact of control strategies on electrolyzer performance, cost, and efficiency.

The NEWP Lab looks forwards to thinking with the models this work develops towards other applications where the challenge of balancing trade-offs between system flexibility and cost might instead be viewed as an opportunity to learn and develop control strategies and design models for renewable electrolysis systems. Our group extends gratitude to the Sargent Centre for Process Systems Engineering at Imperial College London, the Dutch Institute for Sustainable Process Technology (ISPT), Ministry of Economic Affairs and Climate Policy and Top Consortia for Knowledge and Innovation in Energy and Industry for Dr Cooper’s involvement in the grid-scale Hydrohub GigaWatt Scale Electrolyser project and their support in this work. The NEWP Group congratulates Mahdi Sharifzadeh, Nathanial Cooper, Hans van’t Noordende and Nilay Shah on this exciting publication.

Congratulations, Sharifzadeh et al.!
