Hydrogen and renewable energies

Energy: Carbon-Free

The pioneering spirit is a critical part of our technical and engineering DNA, which has led us to energy "firsts" such as seals in the world's first subsea gas compression system and designing solutions for extreme environments in deepwater, HPHT, floating production and cryogenic transfer. Our technical team recently achieved another "first," qualifying Omniseal® spring-energized seals in the world's first Liquefied Hydrogen (LH2) loading arm in the receiving terminal at Kobe, Japan, airport island. Projects such as these are ways we are partnering with key companies in the hydrogen value chain, developing advanced sealing solutions and material technologies.

Backed by this heritage, we continue to innovate today and solve the challenges that affect our communities. A high priority is finding out how can we decrease global emissions and address the impact of climate change. Our team is dedicated to decarbonating the energy sector by developing bespoke materials and sealing technologies, serving the needs of the entire hydrogen value chain and addressing the challenges of Carbon Capture Utilization and Storage (CCUS) projects and other emerging energy sources. 

Working in collaboration with major companies dedicated to low emissions and through repeated internal testing, our experts have gained tremendous knowledge of the requirements needed for these new applications. This meticulous scientific process has enabled us to better guide our customers and recommend reliable and precision solutions capable of operating in a wide variety of extreme conditions in gaseous or liquid hydrogen, electrolyte solutions, and 100% carbon dioxide. 

By actively engaging with our customers' engineers and R&D teams, the combined efforts have clearly shown to work in solving technical sealing and material challenges and delivering renewable energy and breakthrough decarbonization technologies.
