"It is important to arrive at accepted standards and methods for assessing such technologies. DNV's recommended practice will help energy scientists in the first phases of development, as well as investors and operators manage the risk of failure and lack of intended quality in new CO2 capture technologies," said Bjorn-Erik Haugan, executive director of Gassnova.
According to an International Energy Agency scenario, energy demand is projected to rise by over 60% until 2030. By then, more than 80% of the energy sources will be fossil fuels. The negative environmental effects of continued use of fossil fuels can only be offset by the development of new technology solutions. Limiting CO2 emissions from energy generation is a key to reducing emissions of greenhouse gases, and hence carbon capture and storage could play an essential role in the development of a more sustainable energy system.
However, technology presently available is costly, entails high operating costs, or is not proven to work in large-scale commercial installations.
Need for qualification of CO2 technologies
The Norwegian government established Gassnova to spearhead the mission of shepherding these technologies to market. "As new technologies are initiated and developed, authorities and stakeholders will create requirements and regulations governing how these technologies function," said Haugan. "Therefore, we are funding DNV to develop new guidelines to qualify technologies for natural gas power generation that capture or limit emission of CO2. Employment of such accepted working practices by project developers, oil and power companies will reduce risks when implementing new technologies," said Haugan.
These new guidelines will be based in DNV's existing recommended practice "Qualification Procedures for New Technology," which supports energy companies in their effort to develop, test, and implement new technology. Since 2001, the practice has been employed in more than 30 successful qualification programs for new technology.
Must reduce risk for failure and emissions
"World-wide, there are several substantial efforts underway to develop new technologies that will reduce CO2 emissions during power generation from natural gas," said Havard Thevik, DNV's Project Manager. "However, technology researchers, operators and authorities must minimize the risk for failure. Major risk issues related to gas-fired power plants with CO2 capture are the plant uptime and the actual capture ratio of CO2. Another key issue is related to operating costs of new CO2 capture technology, such as degradation of absorbants or possible high maintenance costs to keep CO2 capture levels high. It is also imperative to address any possible health, safety or environmental concerns related to the new technology."
"Currently, Statoil, Statkraft and Hydro are partners in the project. A first guideline draft will be delivered by the end of 2006. The final recommended practice document will be available within the summer of 2008. We are grateful for Gassnova's support to this 3,6 MNOK project that we see as critical to meeting the global concern of reducing CO2 emissions to the atmosphere," added DNV's Research Program Director Stale-Selmer Olsen.
DNV is a global provider of services for managing risk. Established in 1864, DNV is an independent foundation with the objective of safeguarding life, property and the environment. DNV comprises 300 offices in more than 100 countries, with 6100 employees.
Gassnova, center for sustainable gas power technologies, was established by the Norwegian Ministry of Petroleum and Energy to stimulate the development of technology for natural gas power generation with Carbon Capture and Storage (CCS). The two most important challenges are to reduce the costs related to handling of CO2 and to create public acceptance for geological storage as a climate measure.
In order to stimulate activity, Gassnova provides financial support to technology development projects to both domestic and international enterprises, and work to establish arenas that bring government agencies, research institutions and industry together. Gassnova is a governmental center of expertise, providing professional support to the public administration through advisory services, studies and reviews.
