Objectives

In our transforming world, the conventional fossil-based energy ecosystem favors blue hydrogen because of cost, time, and scale-up limitations, whereas the renewable energy sector champions green hydrogen. However, both miss the “transition” part in which we see a spectrum of change. This research aims to investigate the synergy between blue and green hydrogen technologies in facilitating the transition and collaboratively driving secure, affordable, and reliable energy solutions across heavy industry.

Abstract

This presentation employs a comparative analysis of blue and green hydrogen technology solutions as developed by Technip Energies and Rely, discussing their roles in achieving secure, affordable, and reliable energy. It covers developments in raw materials, energy consumption, CO2 intensity, and specific technological features, highlighting their potential to decarbonize various sectors.

The presentation examines different project scenarios and timelines, categorizing them into brownfield existing users, brownfield newcomers, and greenfield newcomers. By using the steel industry or ammonia production as case studies, it explores retrofitting challenges.

The findings reveal that while it is commonly believed blue and green hydrogen technologies have distinct roles due to the speed and affordability of installing blue technology, innovation indicates other possibilities. The research highlights Rely and T.EN’s capabilities in the parallel development of technology that makes both blue and green hydrogen more scalable and more competitive, including the development of productized plants like Rely’s Clear100+.

The co-development is key as T.EN brings 60 years of hydrogen experience, as a molecule with unique needs, allowing Rely to capitalize on expertise in hydrogen infrastructure, including safety, transport, storage, choice of material, and environmental impact. This expertise allows Rely to industrialize and scale green hydrogen technology better than other players.

Rely discusses a project in Kakinada, India, which is the world’s first 100% conversion of grey to green ammonia. As a 100% conversion, it is an example for future projects but also sheds light on different ways retrofitting challenges can be handled. This includes the project’s unique renewable energy mix to deal with intermittency.

Conclusion

This research showcases the unique strength of T.EN-Rely partnership, which is key for the parallel development and growth of both blue and green hydrogen. While T.EN continues to develop blue hydrogen solutions, Rely pushes boundaries with the faster scaling of green hydrogen, such as in Kakinada, India, helping industries decarbonize, each at their adapted shape, pace, and trajectory.
