Sulzer, a leading independent service provider (ISP) and Crosstown H2R, an innovation-focused Swiss technology firm, have joined forces to develop the next generation of H₂ combustion systems to solve today’s global energy challenges. Together, their modernization technology will play a key role in eliminating CO₂ emissions from existing gas turbines across Europe that they can continue to operate reliably for decades.

Original gas turbine manufacturers often prioritize new installations, providing opportunities for service providers like Sulzer to invest in engineering technology to offer viable alternatives for operators. To develop advanced service offerings for gas turbine upgrades, Sulzer works with specialist innovators such as Crosstown H2R.

During October 2023, in partnership with Crosstown H2R, Sulzer unveiled revolutionary H₂ combustion technology designed for the aeroderivative, industrial and power generation gas turbine fleet, positioning the installed gas turbines for a sustainable, emission-free future. In a paper presented at a conference at the ETN’s 11th International Gas Turbine Conference (IGTC), the companies described this innovation, which attracted great interest. This joint initiative between Sulzer and Crosstown H2R not only addresses the urgent need for decarbonization but also offers a cost-effective, reliable, and environmentally friendly solution.

By integrating an advanced micromixer into the existing combustion system, this technology represents a step forward from conventional burner types. The upgrade, which can be carried out during scheduled overhauls, involves replacing the existing burner and preparing the entire combustion system to accommodate the new component, making the turbine capable of flexibly using multiple fuels e.g., from 100% natural gas to 100% H₂. H₂, with a combustion flame speed around seven times faster than natural gas, necessitates a combustion system upgrade. A key technology is the burner, which ensures seamless handling of any level of H₂ fuel. The overall upgrade integrating the new burner ensures reliable and efficient operation.

"At Sulzer, we are committed to providing cutting-edge alternatives for gas turbine operators. Our collaboration with a specialized technology company, like Crosstown H2R, underscores our dedication to pushing the boundaries of technology," said Tim Schulten, Division President of Sulzer Services. "By leading this development, we empower our customers to transition to zero carbon operations, without the need for complete and expensive engine replacements."

“Crosstown H2R is thrilled to collaborate with Sulzer, the leading ISP in the sector, renowned for their innovative solutions and we are poised to introduce the H2R burner to their large customer base. Together, we are making a meaningful contribution to decarbonizing Europe’s existing gas turbine fleet. It is an exciting time for us to collaborate on a sustainable energy future, and we look forward to making a positive impact,” said Dr. S. Prith Harasgama - Co-CEO & Founder of Crosstown H2R.

The innovative H2 combustion technology, slated for its first commercial implementation in the second half of 2024, is a testament to both companies' commitment to advancing greener energy solutions. Sulzer's expertise in gas turbine retrofitting, coupled with Crosstown H2R's proprietary burner technology, is revolutionizing the industry by transforming existing gas turbines into essential, future-proof infrastructure.
