The IEA supports international energy technology research, development, deployment, and knowledge transfer through multilateral groups (formally called Implementing Agreements). The experts participating in the activities of the Implementing Agreements represent public and private sector entities worldwide. Together, these experts share knowledge – and resources – to advance energy technologies.
The industry sector currently accounts for 27.3% of the world’s energy use and is thus responsible for a significant share of global CO2 emissions (22.6%). Improving industrial energy efficiency offers the most cost-efficient measure to reduce greenhouse gas emissions. Energy efficiency improvements are possible in heavy industries such as iron and steel, cement, petrochemicals, chemicals, pulp and paper, aluminium, and food processing. Raising awareness of the financial and environmental benefits of these improvements must be balanced against the additional investments required to implement changes. Fiscal and financial policies and measures designed to support heavy industry are an important first step.
The aims of the Implementing Agreement on Industrial Energy-Related Technologies and Systems (IETS IA) are to accelerate the research and share the results of cost-effective new industrial technologies and system configurations that increase productivity and product quality while improving energy efficiency and sustainability. The IETS IA currently focuses on the energy-intensive process industries and technologies, but is moving to expand research into other industrial sectors and to facilitate cooperation between different industrial research disciplines. There are eight Contracting Parties.
Integrated steelmaking is complex, involving a series of industrial processes and producing a number of by-products, including excess process gases which are used to create electricity. Gaining a better understanding of the complex processes and energy intensity of the steel industry will improve efficiencies and reduce greenhouse emissions, currently responsible for 6% to 7% of CO2 emissions worldwide.
The aims of the IETS IA project, Development and Use of Process Integration in the Iron and Steel Industry, are to advance the application of process integration1 as a method to reduce energy consumption and lower greenhouse gas emissions in the steel sector. Applying process integration in the steel industry is a relatively novel approach that is rapidly evolving.
As a result, communicating the methods and results to industry stakeholders who are unfamiliar with the advantages of the apporach will be a challenge. For this reason, the IETS IA holds workshops to bring together a cross-section of steel companies, research institutes and universities.
One example of process integration includes the relationship between fluid dynamics and energy recovery. One particular pilot reactor includes a high-speed video camera that provides insight into the rate of dry slag granulation in the steelmaking process.
Outcomes of the project include a network of experts in the sector, a database of proven technologies, and a guidebook.
