A five month test program to capture carbon emissions from the municipality operated Klemetsrud waste to energy plant in Oslo, is being undertaken by Aker Solutions, a Norwegian supplier of products, systems and services to the oil and gas industry.
According to the company the project is the first of its kind globally for a waste to energy plant and comes after Aker Solutions signed a contract with the city government in December.
The plant is Norway's largest waste to energy facility with a capacity to burn 310,000 tonnes of waste per annum. It has been in operation since 1985 and generates some 175 GWh of electricity and 750 GWh of district heating annually.
Akker explaine that Carbon Capture and Storage (CCS) is an important tool in reducing CO2 emissions and curtailing global warming. The test will be a key element in qualifying Aker Solutions' amine-based CO2 capture technology for commercial application at waste to energy plants globally.
"This is pioneering work with significant potential as the world focuses on finding ways to limit carbon emissions," said Valborg Lundegaard, head of Aker Solutions' engineering business. "As such, this pilot project is of international importance."
The test will be conducted using the company's mobile test unit for carbon capture. The gas released from the Klemetsrud waste to energy plant is said to contain about 10% CO2 and is treated in several steps before it enters the mobile unit. Klemetsrud, which gets a majority of its feedstock from biomass, emits about 300,000 tonnes of CO2 per year.
The mobile test unit has been in continuous operation at industrial sites since 2008. It is designed, constructed and operated by Aker Solutions. It is claimed to be a complete carbon capture facility in small scale and can be efficiently installed at sites to test the performance of capturing CO2 from various flue gasses.
"We expect to capture up to 90% of the CO2," said Oscar Graff, head of CCS at Aker Solutions. "The tests will verify important operating parameters such as energy consumption, solvent degradation, losses and required solvent make-up."
The project is funded by Gassnova, the state enterprise which supports the development and demonstration of technologies to capture carbon dioxide (CO2).
"We see potential in this market across the world," concluded Lundegaard.

Recycling and energy recovery prevented the release into the environment of 84% of the 11.3 million tonnes of toxic chemical waste managed at the U.S. industrial facilities according to the U.S. EPA annual Toxics Release Inventory report.
Danish waste to energy technology manufacturer, Babcock & Wilcox Vølund, has been awarded a contract for more than $90 million to design, manufacture and build a waste to energy power plant near Haresfield, Gloucestershire, UK.
