Linden Cogen Successfully Integrates Hydrogen Blending

Published on: 

The project is expected to reduce CO2 emissions and improve overall operational efficiency by blending hydrogen into natural gas for power and steam generation.

Linden Cogeneration (Linden Cogen) has announced the successful commissioning of its hydrogen blending initiative, marking the commercial application of this technology. The project is expected to decrease CO2 emissions by substituting natural gas used for power and steam generation with hydrogen.

Following the incorporation of various enhancements, such as PSM’s FlameSheet system, Linden Cogen is now blending refinery off gas, which includes hydrogen produced by the Phillips 66 Bayway Refinery, with natural gas to fuel its unit 6 gas turbine. This collaborative venture aims to improve the operational efficiency of both the refinery and Linden Cogen and decrease CO2 emissions, mainly through the utilization of refinery off gas and enhancements in flare efficiencies.

Todd Kerschbaum, Chief Technical Officer for JERA Americas, half owner and asset manager of Linden Cogen, said, “We successfully implemented the new technologies and commercialized the operations. The actual reductions will depend on the amount of hydrogen used at any particular operational period, but the project is expected to reduce overall CO2 emissions by approximately 10% of annual CO2 emissions from unit 6, while meeting the gas turbine’s stringent NOx emission requirements.”

Donald Susanen, Bayway Refinery General Manager, expressed Phillips 66's commitment to the energy transition and lower-carbon initiatives, citing the joint project with Linden Cogen as an example. He also expressed satisfaction with the project’s anticipated improvement in energy efficiency and reduction of CO2 emissions.


Linden Cogen is a 972 MW natural gas-fueled thermal cogeneration plant in Linden, New Jersey, supplying power and steam for industrial usage under long-term contracts and selling most of its electricity into the New York Independent System Operator and PJM power markets. The facility, in operation since 1992, comprises six gas turbines and three steam turbines, and it is owned by JERA Americas (50%), EGCO (28%), DBJ (12%), and GS-Platform Partners (10%).

JERA Americas, a subsidiary of Tokyo-based JERA, aims to support an environmentally and socially responsible energy transition. The company produces roughly 30% of all electricity in Japan and is committed to achieving net-zero CO2 emissions from its businesses by 2050.

Phillips 66, a diversified energy company headquartered in Houston, manufactures, transports, and markets products essential to the global economy, and is committed to providing energy safely and reliably while pursuing a lower-carbon future.
