Yara CCS project
Yara Porsgrunn has captured CO2 at their ammonia plant since 1988. Yara has total emissions of approximately 1,2 million tons of CO2 a year at full production, 0,8 Mt is captured and some of this is sold to the food industry and other goods. They state that they can capture 210 kt CO2/year with proven/excisting technology, in the future.
Yara has provided input to the state driven pre-feasibility study from 2012 and on. In 2016 they are one of three potential industrial CCS project left in the process . The desicion on which project(s) that will be chosen for further study and development is set to autumn 2016. The investment desicion is planned for 2018.
Yara International is a global scale fertiliser manufacturer producing a little over 20 million tonnes of nitrogenous fertilisers and associated products and with annual greenhouse gas (GHG) emissions of about 10mt of CO2 equivalent.
Yara are considering their ammonia plant in Porsgrunn as relevant for further studies in CO2 capture and are now in the same feed study process as Norcem. Yara overall emissions are about 1.2 million tonnes of CO2 annually at full ammonia production, and they sell some of this to the food industry. Approximately 0,8 Mt is captured a year, 0,2-0,3 of this is sold and the rest is emitted.
Yara, Ineos and Norcem (all in the same area; Grenland) have managed to reduce its emissions. These firms may be appropriate candidates for concrete cooperation on CO2 sequestration, also because of the proximity geographically. The challenge remains to develop better framework for the processing industry to invest in environmental technologies.
To capture CO2 from industrial processes has some advantages like lower capture cost, excess energy that can be used for CO2 capture and stable CO2 source. They are often also located in industrial clusters/coastal locations which can possibly lower transport cost. And as for Yara they have often industrial experience from commercial use.
The area of Grenland has already 100 jobs related to CO2 management. Gassnova, the Norwegian state-owned enterprises for CO2 handling, are also located in Porsgrunn The same is the college in Telemark which is the forefront of research on CO2 capture and storage. It is smart and necessary to strengthen such clusters of expertise and experience to just areas with large CO2 emissions.
The Yara project can represent a major breakthrough and be important for a huge industrial area and emitter. The project is seen as relevant and realistic, mainly due to their considerable experience in CO2 conditioning, handling and transport, yara understands chemical processes and is comfortable executing large projects, comparable to CCS. Another factor is that some of the emission points at Porsgrunn have a relatively high CO2 concentration making CCS less technically challenging for those streams.
Yara is keen to explore decarbonisation initiatives including CCS, though this needs to be assessed on a commercial basis. In this context, Yara is keeping a close watch on developments in the EU ETS (and other carbon tax developments) as well as potential new utilisation options for CO2.
This is a steam methane reforming process. ~0,8 Mt CO2/y is captured from the process, then liquified, transported by ship and sold to food grade.
5 Mt of CO2 have been transported since 1988 (in 2015) without any safety issues.
Yara Porsgrunn states that they can capture 210 kt CO2/year with proven/excisting technology.
From the worldwide ammonia production, ~130 MtCO2 is captured.
The Porsgrunn site is located at Herøya outside Porsgrunn, about 140 km southwest of Oslo. The site covers an area of approximately 1.5 square kilometers.
The site has one ammonia plant, three nitric acid plants, two NPK plants and two calcium nitrate (CN) plants.
Their estimated figures (2015) states that CO2 captured (C1,2) is 420 kilo tonnes a year, approx at 96-98 vol% CO2.
CO2 emissions from the ammonia production represent approximately 60 % of the total GHG emissions from Yara Porsgrunn. The remainder is nitrous oxide (N2O - laughing gas).
