Enabling energy transition

The need to mitigate climate change and deliver secure and affordable power is driving a fundamental revolution in energy use, energy sources and energy delivery. Decades of use of high-performance mechanical sealing technology developed by John Crane has contributed to the prevention of millions of tonnes of methane and other high-intensity greenhouse gases from being released into the atmosphere from oil and gas infrastructure. The same technology is being used in the energy infrastructure of the future for both hydrogen and carbon capture.
