A new hydrogen blending technology has been commissioned at the New Jersey power plant Linden Cogeneration.
The initiative aims to reduce CO2 emissions by minimizing the use of natural gas for power and steam generation. Linden Cogen is a 972-MW natural gas-fueled thermal cogeneration plant featuring six gas turbines and three steam turbines.
Following certain modifications at the plant, including the installation of PSM’s FlameSheet system, Linden Cogen says it is now taking refinery off gas containing hydrogen produced by the Phillips 66 Bayway Refinery, also located in Linden, and blending it with natural gas to fuel the unit 6 gas turbine.
It adds that the project is enhancing operational efficiency for both the refinery and Linden Cogen while reducing CO2 emissions, primarily through the utilization of refinery off gas and improved flare efficiencies. Hydrogen, which itself is carbon free, can be extracted from methane gas utilizing steam reforming technologies or electrolyzers.
“Actual reductions will be based on how much hydrogen is used at any given time of plant operation, but the joint project is expected to reduce overall CO2 emissions by approximately 10 percent of annual CO2 emissions from the unit 6, while staying within the gas turbine’s stringent NOx emission requirements,” said Todd Kerschbaum, Chief Technical Officer for JERA Americas, Asset Manager and half owner of Linden Cogen.
Linden Cogen is jointly owned by JERA Americas (50 percent), EGCO (28 percent), DBJ (12 percent), and GS-Platform Partners (10 percent). The power and steam generated by the facility are supplied to industrial consumers through long-term contracts, and a significant portion of the electricity is sold in the New York Independent System Operator and PJM power markets.
Linden Cogen began operations in 1992.
