This webinar presents a synopsis of an ongoing study on the development and implementation of high efficiency, low emission (HELE) coal-fired technologies in Japan and South Korea, and in the wider South East Asian region.
The coal fleets of both countries are highly efficient, with the Japanese fleet reported to be the most efficient in the world and the evolution of both fleets has been modelled as in previous IEA CCC HELE studies. Both countries have proactive assisted funding programmes that enable the introduction of HELE plant to countries seeking to develop and improve their coal-fired generating capacity and these outreach activities have been studied.
In this presentation, we will concentrate on the technical means available for achieving high flexibility in coal-fired power plants. This involves providing resilience to frequent start-ups, meeting major, rapid load changes, and providing frequency control duties. Operating at widely variable output increases the wear and tear on equipment and reduces efficiency. However, potential damage mechanisms are well known, and the necessary flexibility can be achieved with acceptable impacts on component life, efficiency and emissions. Designs being developed to enable flexibility in future plants will also be outlined.
There is a lot of industry buzz around HELE (high efficiency low emission) technologies. These advanced coal-based systems include IGCC, polygeneration, oxyfuel combustion, supercritical CO2 and the Allam Cycle, fuel cells, chemical looping, and renewable-coal hybrids. But just how well do these technologies work? Are they close to commercial deployment? And, if not, what is needed to get them there? This webinar will summarise the latest in state-of-the-art coal-to-power technologies and will give an overview on the status of their development.
Our next webinar explains the mission of the IEA Clean Coal Centre and how we operate. It covers how our work ties into the UN sustainable development goals, it goes in to some detail on the topics we cover in our research, technical workshops and outreach activities.
Carbon capture and utilisation (CCU) is attracting increasing interest worldwide. At present, there are a wide variety of CO2 utilisation technologies being explored, each at various stages of development and commercialisation. This webinar reviews the current state of CCU
technologies and analyses their potential environmental impacts.’
In this webinar we will consider potential uses for coal beyond power generation and steel blast furnace furnaces. There are opportunities to use coal derived feed stocks in chemicals, minerals, agriculture, new materials and pollution control. With the electrification of energy use that is projected to double by 2040 this is raising demand for new materials and minerals that can be derived from coal to support renewable energy generation and the electrification of ground transport. The problems of desertification and fresh water supply are set to increase and coal products can be used to mitigate soil erosion, improve water quality, and also reduce emission from fossil fuel power plants.
The recent discovery of new forms of carbon is leading to applications in energy storage, aerospace and composite materials. When considering new carbon-based materials a major issue is the source of carbon and whether it is suitable to use a coal feed stock, and what the effect of that is on the quality of the product and the manufacturing complexity. In addition to new applications for carbon there is an established coal to chemicals industry that provides a host of everyday products that is encountering new environmental challenges. The versatility of carbon means that this webinar will cover a broad range of topics exploring issues and opportunities for the non-energy uses of coal.
Before the price recovery in 2016, the price of internationally traded coal took a downward trend for five consecutive years, forcing coal producers to rationalise their operations. Today we see the export coal industry in a much healthier situation, with stronger prices and a lower cost base. This webinar will examine the costs of production of coal from major exporting countries around the world, and look at how cost trends have changed over the years.
Inevitably, the production of coal creates various waste streams, some of which contain enough residual coal to give them potential as sources of energy. Some types may be used directly or alternatively, reprocessed to recover their coal content. They can form low cost fuels that reduce the demand for fresh coal. Furthermore, their use helps minimise the amounts stored in dumps or settling ponds, reducing their unwanted environmental impacts.
This webinar will examine the types of wastes, the amounts generated, and their utilisation for the main coal-producing countries.
