CaO) at different operating conditions. We
have initiated a modelling activity to describe
and analyze observed performance trends,
and have applied in-situ X-ray diffraction and
in-situ Infrared Spectroscopy.
• The Chemical Looping Combustion model was
developed further to include hydrogen as fuel.
The model was used to simulate industrial
steam generation processes for refineries and
benchmark against gas boilers.
Application to industry and offshore
• A model for CO
2
capture from refineries using
MEA was established in HYSYS. The model
was automated by developing a HYSYS Visual
Basic tool to manipulate parameters, run case
studies and export results to Excel. The effect
of CO
2
capture rate on the specific reboiler
duty was studied.
• Steam cycle design for an offshore oil and gas
installation with CO
2
capture was performed
keeping in mind the constraints of space
and weight. Three different steam cycle
configurations were designed, modelled, and
simulated. In addition to the energy and mass
balance results, a weight assessment of the
major equipment was done.
• Collaboration with SP4 to include the
attainable region approach for design of
membrane processes.
Integrated assessment
• Review paper “Hydrogen production with CO
2
capture” submitted to International Journal
of Hydrogen Energy. The paper provides
an overview of technology option for H
2
production from fossil fuels with CO
2
capture.
• Sizing and costing has been undertaken for
the Natural Gas Combined Cycle (NGCC)
power plant with solvent capture for MEA and
a Novel Generic Solvent (NGS), and also for
the NGCC with Ca-looping capture.
• CO
2
capture for the NGCC with polymeric
membranes (90% capture rate) was
investigated for three different combustion
configurations: conventional gas turbine, gas
turbine with exhaust gas recirculation (EGR)
and gas turbine with EGR + Supplementary
Firing (SF). The NGCC + EGR option was found
to have the best performance with a capture
penalty of ~10%-points. However, the study
clearly indicates that membrane capture from
the NGCC has its optimum performance at
lower capture rates (~60%).

Hydrogen cars: The role of fossil fuels and CCS in a cleaner transport system
Kristin Jordal, David Berstad and Petter Nekså
In short, a possible solution for hydrogen
production for cars could be to use fossil fuels.
We will tell you why and how!
Currently, road transport contribution to
global CO
2
emissions is around 23%.
