With the ongoing challenges posed by geopolitical uncertainties in key energy-producing regions such as the Middle East and Russia, the fragility of our energy supply and the importance of developing a more resilient global energy system are clear and widely recognized. Yet energy prices are rising, and coal production remains high – despite the long-term trend towards cleaner sources.¹

Energy security and the transition to more renewable energy are critical priorities for both governments and industry, but efforts of this magnitude require significant investment, innovation and collaboration. This is where Sulzer’s ongoing commitment to excellence creates significant value for essential industries around the world, delivering impactful efficiency improvements and customized support solutions for complex technologies.

Driving cleaner, more efficient practices

Together, Sulzer and TechnipFMC, a global energy systems leader, are demonstrating their combined expertise and industry leadership in developing groundbreaking new CO₂ pump solutions to help bring revolutionary subsea processing technology to life. Petrobras’ HISEP® technology enables the separation of CO₂-rich natural gas from oil directly at the seabed, rather than transporting it to the surface for topside separation, as traditionally done on Floating Production Storage and Offloading (FPSO) vessels. While topside separation allows the CO₂ gas to be reinjected into the reservoir, it is highly energy intensive.

Subsea separation provides significant gains in energy efficiency and productivity, while reducing emissions. Since 2017, Sulzer has been collaborating with TechnipFMC to develop CO₂ pumps for Petrobras’ HISEP® technology. This year, following the successful validation of a prototype, three customized 6 MW high-pressure centrifugal (HPcp) pumps were delivered to Petrobras for testing and validation at Brazil’s Federal University of Itajuba. Once confirmed, our advanced new pump technology will support and enable the gas, rich in CO₂, to be separated and immediately reinjected into the reservoir at the seabed, 2000 m below the waterline.

In addition to our work in subsea processing, our solutions are also delivering sustainable benefits in renewable energy production. In China, for example, our molten salt pump technology and expertise was selected this summer to help overcome the challenge of intermittent renewable energy. More recently, another of our customized solutions was selected by a leading Chinese chemical and energy company to help meet the growing demand for sustainable aviation fuels (SAF). These examples highlight how our technical expertise and commitment to higher efficiency and lower emissions are contributing to energy security.

Supporting critical infrastructure and development

Sulzer’s innovations in wastewater pumping, noise reduction and treatment efficiency continue to set new industry standards and address some of the world’s greatest challenges. Recently, we advanced a Guinness World Record in agricultural water treatment by enabling improved efficiency for water reuse in Egypt to promote agricultural productivity and food security. The New Delta Treatment Plant, the world’s largest water treatment facility, relies on our energy-efficient flow technologies to reuse treated agricultural drainage water and wastewater. This clean water is then used to contribute to the cultivation of 1.2 million acres of land in the West Delta region, almost twice the size of Greater Cairo.
