![]() For a dedicated gas heated reformer (GHR) located downstream of an aeroderivative gas turbine engine, followed by a two-pressure level HRSG and a capture plant with one absorber, the integrated system produces ca. This corresponds to 34 MWe of additional power, increasing efficiency by 4.9% points, and makes one absorber redundant compared to the equivalent non-integrated system producing the same volume of H 2. 696,400 Nm 3/h of H 2 with a net power output of 651 MWe at a net thermal efficiency of 38.9% LHV. ![]() For a conventional SMR located downstream of an H-class gas turbine engine, followed by a three-pressure level HRSG and a capture plant with two absorbers, the integrated system produces ca. It includes a generic post-combustion capture technology – a conventional 30%wt MEA process - to quantify the reduction in size of CO 2 absorber columns, the most capital intensive part of solvent-based capture systems. A newly developed, rigorous, gPROMs model of two hydrogen production technologies, covering a wide range of hydrogen production capacities, thermodynamically integrated with commercially available gas turbine engines quantifies the step change in thermal efficiency and hydrogen production efficiency. The concept would be widely applied to any post-combustion CO 2 capture process. The novel contribution of this article consists of using sequential combustion in a steam methane reforming (SMR) hydrogen plant to allow for capital and operating cost reduction by using a single post-combustion carbon capture system for both the hydrogen process and the combined cycle gas turbine (CCGT) power plant, plus appropriate integration for this new equipment combination. In future energy supply systems, hydrogen and electricity may be generated in decarbonized industrial clusters using a common infrastructure for natural gas supply, electricity grid and transport and geological storage of CO 2. 2Department of Mechanical Engineering, The University of Sheffield, Sheffield, United Kingdom.1School of Engineering, The University of Edinburgh, Edinburgh, United Kingdom. ![]() Laura Herraiz 1* Mathieu Lucquiaud 1 Hannah Chalmers 1 Jon Gibbins 2 ![]()
