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.
Many countries have strict emission limits for nitrogen oxides (NOx) and so NOx control systems are widely used on coal-fired power plants. India has recently introduced NOx emission limits so pollution control technologies will need to be installed. This webinar will review available NOx controls for coal-fired units in general. With examples of recent developments, systems that could be successfully applied in Indian power plants are identified. The challenges facing Indian utilities are also considered. The new Indian standards have created opportunities for equipment manufacturers, as well as a need for global technology leaders to modify their products to meet local market requirements, particularly high ash content coal.
This webinar will review the supply chain costs of biomass cofiring. In order for cofiring to continue to play a long-term role in a emissions reduction strategy it must be competitive with other renewable technologies in terms of cost and CO2 abatement potential. Tune in to get a better understanding of the current supply chain costs, analysis of the emissions associated with biomass utilisation and the possible effects of government policy on future deployment.
Significant areas of the world are facing a high level of water stress. This webinar will look at the the power generation industry and the challenges it is facing with water availability. Power plant operators can reduce their dependence on fresh water by using non-fresh water sources and conserving water within a power plant. The emphasis will be on the treatment of wastewater from coal-fired power plants and its reuse.
This timely webinar will review the implications of development and deployment of HELE (high efficiency, low emissions) coal power technologies. Some 40% of world power generation comes from coal, which means huge CO2 savings are possible by using HELE technologies. Therefore it is essential to support the use of more efficient coal-fired power, as it's the only realistic way to bring down CO2 emissions. The aim should be to minimise the emissions of CO2 from coal, through improvements in efficiency and the subsequent introduction of CCS.
This timely webinar will review the implications of the Minamata Convention on Mercury on coal. COP1, the 1st Conference of the Parties, of the convention was held in Geneva at the end of September. Tune in to to get a full update on the final text of the Minamata Convention on Mercury and a discussion on the potential consequences for emerging economies who have a significant dependence on coal.
UNEP (the United Nations Environment Programme) first raised the issue of mercury as the most important, unregulated, pollutant in the global environment in the mid 2000s and, in response, established the first INC (International Negotiating Committee) and the UNEP Partnership Areas in 2008. The IEA CCC has been lead of the Coal Partnership since its inception.
Coordinating mercury reduction programmes throughout the world will include numerous social, economic and technological challenges and will be dependent on technology transfer as well as significant international funding. By the time COP1 of Minamata eventually closed, 83 countries had signed the Minamata convention and committed to developing national implementation plans. The next step will be the acceptance of those plans and, ultimately, the movement of these plans into action.
Carbon capture and storage must be implemented on a global scale if ambitious targets for greenhouse gas emissions are to be met, yet deployment of the technology over the last decade has been slow. CCS faces a number of unique barriers, including high upfront costs and investment risks, uncertain public and political support, and a need for new regulatory regimes. To help overcome these barriers, a number of formal collaborations have been established between countries with commitments to CCS development. Multilateral initiatives such as the Carbon Sequestration Leadership Forum and the Clean Energy Ministerial have sought to share research experience, spread favourable policy and regulation, promote public acceptance, and build mutual trust on commitment to CCS. Several bilateral agreements, often between an OECD country and China, have also been created over the last decade with a view to promote investment and joint research into CCS. This webinar will briefly review the barriers to CCS development and highlight the work of some key multilateral and bilateral initiatives, as well as the challenges they have faced.
This webinar addresses the environmental effects of coal mining and related transport, reviewing the potential environmental impacts arising at all stages of the coal chain. Potential environmental impacts from emissions of dust, water, and local land use are reviewed, highlighting emerging techniques to limit and reduce negative effects.
Examples of best practice for mine operation, transport logistics and dust control will demonstrate the potential for improved performance and environmental sustainability in the field. Socioeconomic impacts, as well as regional employment and community engagement, are also covered. In this day and age mining companies will need to comply with environmental law as well as demonstrating best practice and public engagement to have new projects approved.
This webinar sets out the results of an examination of the prospects for HELE (high efficiency, low emission) technologies in ten major coal-using countries. A recent study examined the role of HELE coal-fired power plant in helping to meet the goal of reduced carbon dioxide emissions. A number of smaller but still significant coal-using counties, based mostly in South East Asia, have attracted attention regarding the future development of their coal-powered generating fleets to meet the needs of their developing economies. These countries are: Bangladesh, Indonesia, Malaysia, Philippines, Thailand and Viet Nam.
Innovative approaches to improving flexibility and emissions from coal-fired power plants. Combining solar power, or natural gas cofiring with coal-fired power plant. Innovative approaches to improving flexibility and emissions from coal-fired power plants. Combining solar power, or natural gas cofiring with coal-fired power plant.
To remain competitive, coal-fired fleets are having to adapt to meet the changing circumstances. Increasingly flexible operation is a key factor in this, and power generators are exploring possible routes forward. New techniques and strategies are being considered or adopted in order to maintain the commercial and economic viability of coal-fired plants.
There are a number of ways in which power plant flexibility can be enhanced – this webinar explores two techniques that show potential - combining solar energy with coal-fired generation, and cofiring natural gas with coal. Both techniques are already used on a commercial basis, although deployment levels are currently low. However, under the appropriate conditions, both show potential for application to some existing and new-build power plants.
The supercritical CO2 Brayton cycle energy conversion system is an innovative concept that converts heat energy to electrical energy through the use of supercritical CO2 as working fluid rather than through steam and water. In this webinar, Qian will give a brief description of supercritical CO2 power cycles and review the recent technology advances in developing supercritical CO2 cycle power generation systems for fossil fuels.
