At the same time as the world’s energy demand is expected to increase remarkably
over the next decades to come, we have to cut greenhouse gas emissions
proportionally over the same period, to avoid serious climate changes. Only a
portfolio of solutions can realise this goal; fuel switch, energy efficiency, a vast
increase in renewable energy and CO2 capture and storage (CCS).
Statoil works actively to reduce carbon dioxide emissions from our operations and
our products. Fossil fuel, such as oil, gas and coal will be dominant energy sources
for decades to come, and CCS is therefore one of the most important measures in
the long term for reducing carbon emissions globally. According to the International
Energy Agency (IEA) CCS is the single biggest lever for reducing CO2 emissions,
providing up to nearly 20% of the global cuts required by 2050.
Energy realities
Statoil is an international energy company with operations in 34 countries. Building
on more than 35 years of experience from oil and gas production on the Norwegian
continental shelf, we are committed to accommodating the world’s energy needs in a
responsible manner, applying technology and creating innovative business solutions.
We are headquartered in Norway with 20,000 employees worldwide, and are listed
on the New York and Oslo
Gassnova shall provide advice to the Norwegian Ministry of Petroleum and Energy in
matters relating to Carbon Capture and Storage. In addition, Gassnova is to contribute
to the implementation of the technology development programme ”CLIMIT” in
cooperation with the Research Council of Norway. One of the aims of Gassnova’s
work is to develop ways to reduce the costs linked to Carbon Capture and Storage.

2. The Mongstad industrial complex includes a crude oil
refinery, a NGL fractionation plant, a crude oil terminal,
and a combined heat and power (CHP) plant. The facilities
installed are closely integrated and they yearly convert
close to 10 million tonnes of raw materials (crude oil,
condensate, NGL, and gas) to saleable products. The main
products are propane, butane, naphtha, gasoline, diesels,
gasoil, petrol coke and electricity. The crude oil terminal has
a total storage capacity of 9.4 million barrels of crude oil.
The Mongstad harbour is one of the busiest oil harbours in
Europe.
The Mongstad facilities are closely linked to the upstream
activities in the North Sea. Two pipelines bring crude oil
from the Troll, Kvitebjørn and Gjøa fields to Mongstad. A
NGL pipline bring NGL’s from Kollsnes gas terminal and
Sture crude oil terminal. A pipeline brings gas from the
Kollsnes gas terminal to the Mongstad CHP plant, which
returns electricity to the refinery, the Troll installations and
the Gjøa field, in addition to the regional electricity grid.
The purpose with TCM is to test and improve the CO2
capture technologies. TCM are using flue gas from the
refinery cracker, which has approximately the same CO2
content as flue gas from coal fired power plants (about
13%), and flue gas from the natural gas fired CHP (about
3,5%). At least two capture technologies will be tested at
TCM, one based on Alstom’s chilled ammonia technology,
and the other on Aker Clean Carbon’s amine technology.
TCM is a cooperation between the Norwegian state
(represented by Gassnova), Statoil, Shell and Sasol.

Full scale CO2 capture Mongstad (CCM)
The Norwegian government and Statoil are establishing a
full-scale CO2 capture project in conjunction with the CHP
at Mongstad. At full capacity, the amount of captured CO2
from the CHP plant is expected to be around 1,2 million
tonnes of CO2 annually.
Worldwide experience reveals that it takes a long time to
bring carbon capture and storage from the drawing board
to industrial application, meaning that there is a substantial
need for technological development and industrial
experience in order of success.
Tackling CO2 emissions is an important plank in our climate
strategies and the Mongstad plans are a vital part of our
efforts. Technology and full-scale plants provide major
contributions to technological and industrial development
within carbon management.
At Mongstad we will establish capture facilities while
the existing CHP and refinery are in full production.
The facilities are connected to producing fields on the
Norwegian continental shelf, such as Troll and Kvitebjørn,
and this poses additional challenges in relation to safety
and reliable operation.
The full scale CO2 capture plant is classified as a
megaproject due to its size and complexity, as well as the
investment and the new technology involved.
The capture facility will be an open process,- capturing
CO2 from exhaust gas, while Statoil’s previous experience
at amongst others Sleipner and Snøhvit, are capturing CO2
directly from the natural gas stream in a closed process. We
feel dedicated to understand and manage the additional
health and environmental challenges posed on us by
applying an open capture facility.
The CO2 concentration in the exhaust gas from the
CHP is very low. Low CO2 content requires large capture
facilities. The scale-up challenge must be solved, and this
industrialising of the capture technology will be a new
frontier. We are eager to learn from others and want
to have open and fruitful cooperation with the supplier
industry, the research communities and the environmental
organisations.
We regard carbon capture and storage as a crucial tool in
the combat against climate changes and that full-scale
capture of CO2 at Mongstad is pioneering work.
We acknowledge that we will face different challenges
in the years to come, amongst them challenges that are
related to technical multi complexities, scale conditions
and risk mitigation. We also trust that we have developed
a solid approach in order to ensure project completion
and a capture facility that works as designed. Statoil has
accomplished great industrial break-troughs before, and we
are building on our existing industry knowledge achieved
through several decades in business, to accomplish a
successful project at Mongstad.
The collaboration between the state and the industry is
crucial in order of success, and the state is involved in all
the aspects of the project, through its dedicated presence
of state enterprise Gassnova; whose objective is to manage
Norway’s interests in relation to CO2 handling. Gassnova is
responsible for transport and storage of the captured CO2
in cooperation with industrial actors.
Norway is through the Mongstad project, supporting
realisation of a complete value chain for carbon capture,
transport and storage. A final investment decision for this
project is expected in 2016.
