“ Being technology-based is not just about having the right tools – it is a mindset.”
Claire emphasizes that technology at Rely is not just about hardware and systems but also about a way of thinking.“ Being technologybased is not just about having the right tools – it is a mindset. At Rely, we cultivate this mindset across our team and through strategic collaborations. While we have selected John Cockerill Hydrogen as a key technology partner, we are continuously engaging with other partners to push the boundaries of innovation. Our clients expect this level of forward-thinking from us.”
Balancing standardization and customization
While standardization is at the core of Rely’ s strategy, the company also recognizes the need for project-specific customization. To address different client requirements, Rely employs a two-pronged approach:
• Productized solutions – Clear100 + offers a highly standardized, ready-to-deploy green hydrogen plant.
• Customized integration – For clients requiring specific configurations, Rely provides tailored project execution, integrating technologies from multiple OEMs.
“ We offer flexibility while maintaining the efficiency benefits of standardization,” says Claire.“ Clients can choose between a fast-deploy, off-the-shelf solution or a customized approach that meets their specific needs. If a client wants to work with different OEMs or integrate a hybrid technological solution, we have the flexibility to do so. As an integrator, we ensure seamless compatibility and optimize plant design accordingly.”
Digital solutions to optimize performance and efficiency
Beyond engineering and hardware, digital solutions play a crucial role in monitoring, optimizing, and maintaining Rely’ s hydrogen plants. A key development is Rely’ s in-house Energy Management System( EMS), designed to optimize electricity use, maximize hydrogen production, and reduce operational costs.
“ Our EMS enables anticipation, helping operators dynamically manage power demand, integrate with renewables, and ensure that both supply( power) and demand( green hydrogen or its derivatives) are properly balanced through robust planning capabilities,” says Claire.“ Given that electricity accounts for a significant share of costs, this tool ensures that hydrogen production remains as efficient and cost-effective as possible.”
Alongside power optimization, predictive maintenance and real-time monitoring enhance plant reliability and safety.“ By using advanced analytics, we can detect irregularities before they lead to failures. This is the goal,” Claire explains.
To strengthen its EMS, Rely is also collaborating with technology partners specializing in grid management and power optimization.“ We focus on what we do best while integrating expert solutions for power control,” Claire notes.“ This ensures clients receive a best-in-class digital platform for efficient, scalable hydrogen production.”
Expanding the scope beyond hydrogen
In addition to green hydrogen production, Rely is actively engaged in PtX applications, converting hydrogen into valuable derivatives such as green ammonia, e-methanol, and e-SAF( sustainable aviation fuel).
