ETI and PSE launch gCCS - the world’s first full-chain modelling software product for CCS

10 July 2014

July 10th 2014


Process Systems Enterprise (PSE) has launched the latest commercially available product from the Energy Technologies Institute (ETI) – gCCS – a systems modelling environment for whole-chain carbon capture and storage (CCS) applications.


gCCS is the outcome of the ETI’s £3m CCS Systems Modelling Tool-Kit which investigated the future design, operation and roll-out of CCS systems in the UK. It enables simulation of the operation of all aspects of the CCS system and increases the understanding of system-wide operational issues through the use of high-fidelity models of all major CCS operations. Based on PSE’s advanced process modelling environment gPROMS, the tool-kit supports design and operating decisions from power generation through CO2 capture, compression and transmission to injection


Typical applications for the model are:



  • Investigation of flexible operation of a post-combustion capture plant attached to a coal- or gas-fired power station

  • Optimising integration between the power plant and the capture plant

  • Designing optimal compression trains for flexible service

  • Investigating the effects of operational events on the whole CCS system, including multiple CO2 sources, pipeline networks and multiple CO2 stores


Andrew Green, Programme Manager, CCS at ETI comments:


“It is really pleasing that this project has delivered exactly what we set out to do.  It is a great example of the ETI and its Members working in close collaboration with some of the highest quality UK SMEs, resulting in a transformational product which is now becoming publically available. The modelling environment provides robust data and modelling capability to inform decision making in CCS applications. PSE will now take gCCS forward commercially to open up the potential of CCS to a wider market.  I am particularly pleased that one of the first beneficiaries of the project will be ETI Member Shell which is using gCCS to support the design of the Peterhead CCS project”


Further details about gCCS and access to ordering gCCS is available via this link to the PSE website


An overview of the product and its benefits is available through this brochure
