Clean coal (2): Combustion, capture and storage
Speaker abstracts and biographies
Chair: Brian Davey, Manager Large Scale Demonstration Programs, ETIS, Dept of Primary Industries
Brian is teacher trained but has spent most of his working career in the energy sector, first commencing in 1981 until 2005 when he left to develop his own business. He has extensive experience in the finance, marketing and operational sectors of power station management and was closely involved in the privatisation program of the state owned power sector.
Brian’s skills include strategic business planning, negotiation, contract management, employee relations, marketing and plant management.
- the application of drying and combustion technology to wet brown coal on a 200MW unit, the design and installation of a 25 tonne per day carbon capture and sequestration plant (still currently the largest in the Southern Hemisphere);
- the development of a 400MW integrated drying, gasification and combined cycle power station; and
- the largest solar PV station at 154MW in the world.
These projects have a total value exceeding $1.5b.
Most recently Brian has developed the Energy Technology Innovation Strategy large scale Carbon Capture and Storage demonstration program for the Victorian State Government. This has involved the development of the tender documents, an active marketing program and the coordination of the evaluation process. Projects selected from this initiative will form the key foundation projects for the Victorian CarbonNet project.
Total value of projects selected for prefeasibility studies is in excess of $6.0b
Progress Update of the MHI Air Blown IGCC and Gasification Plant
As one of the leading company in the field of IGCC reducing CO2 emission, Mitsubishi Heavy Industries, Ltd. (MHI) is now in a position of actively undertaking its realisation with an integration of two stage entrained bed air-blown coal gasifier, which achieves the highest net plant efficiency by using air as the gasification agent, and M501G (60Hz) / M701G (50Hz) high temperature combustion turbines.
This presentation will discuss the latest activities MHI have been taking at the 250MW IGCC demonstration plant in Nakoso, Japan and its future plan for CCS demonstration. It will also describe such air-blown IGCC+CCS commercial plant projects using “G”-type combustion turbines as the Australian ZeroGen project, for which MHI was awarded the pre-FS work in June 2009.
Furthermore, MHI’s perspective upon smart utilization of Australian brown coal for Coal to X (liquid fuels) will be introduced. MHI believes that our technologies will contribute to energy or fuel resource security and global environmental needs.

Hiromi Ishii, Manager, IGCC Process Engineering Group, Power Systems Project Engineering Department, Power Systems Headquarters, Mitsubishi Heavy Industries Ltd, Yokohama, Japan
Hiromi Ishii is a Process Engineer with more than 15 years of experience in gasifier engineering and boiler engineering on coal/biomass gasification and power generation projects. His project experience covers conceptual design studies, process development and engineering, and turnkey IGCC and conventional boiler projects. He has been involved especially in the field of basic design, feasibility study and process design for defining performances and guarantees at the beginning of the project.
Mr. Ishii has experience in Gasifier process performance calculations, Boiler performance, preparation of heat and material balances, development of Process Flow Diagrams and Piping & Instrumentation Diagrams, specification of mechanical equipments and optimisation studies and so on. He also has experience of gasifier operation and performance analysis on both 200t/d pilot plant test and 24t/d test equipment.
CCS plant design: What does it mean for new and existing coal fired plants?
As there currently isn’t a universal definition of what ‘capture ready’ actually means, there is uncertainty surrounding what is involved in making a plant ‘capture ready’. Furthermore, ‘capture ready’ for a plant in an OECD country may be different to a ‘capture ready’ plant to be built in a developing country. There has been significant international work conducted recently on ‘capture ready’ and what it means. This paper will explore the different definitions and describe some of the plant design issues that need to be addressed in designing and constructing a ‘capture ready’ coal fired power plant.
Why it's important...
Global warming is one of the greatest environmental issues facing the world today. As the power industry is responsible for around 25% of global CO2 emissions, the industry must find ways to produce electricity with far lower CO2 emissions. Carbon capture and storage is a potential means of achieving significant CO2 emissions reduction.

Dr Tadros has presented numerous papers at local and international conferences, both academic and industry based.
Carbon Roadmap: Technological solutions for GHG reduction
As governments (and society) put a price on carbon, the pressure to reduce emissions on businesses engaged in, or controlling, high carbon emission activities and fuel sources is intensifying politically, environmentally and commercially. However we are failing to see tailored, end-to-end mitigation and adaptation strategies, harmonized across national boundaries emerge. We can solve this problem; we can also unleash an enormous amount of economic growth for the future in the process. What you have to do, is have market mechanisms that work more efficiently, and create the environment for the investment necessary to achieve dramatic reductions in GHG emissions across nation states.
The development and deployment of any new technology is an arduous path. All new technologies have a myriad of hurdles that must be cleared before its full potential can be realised. Technologies targeted to reducing global GHG emissions are no exception to this rule and include Energy Efficiency and Recovery, Carbon Capture and Storage (CCS), Renewable power, Advanced gas, Advanced coal and Nuclear technologies.
Significant implementation challenges exist, in part exacerbated by the need to address energy security, climate change mitigation and sustainable development issues. In fact, carbon technologies, and CCS in particular, face greater and far more complex hurdles than any other suite of technologies, yet progress is being made.
Technological change holds the key to both the mitigation costs of reducing CO2 and the adaptation costs of adjusting to climate change. Explicit and higher carbon prices will provide enhanced incentives and rewards for private investment. While we can expect with some confidence, gains in technology in the future, the magnitude of the gains, their timing and their specific areas are unknown at this time.
Ultimately, there will be a need to shift to a new energy economy that involves the use of low or zero emission technologies. The development of such technologies will take time and existing reserves of fossil fuels will continue to play an important role in creating the energy needed to drive societies. As such, we will continue to face the prospect of having to deal with continuing CO2 emission levels from the combustion of fossil fuels worldwide. Given this, the application of a range of technological solutions must be accelerated.
In May 2009 the Global Carbon Capture and Storage Institute (GCCSI) commissioned a WorleyParsons led consortium comprising of Schlumberger, Baker & McKenzie and the Electric Power Research Institute (EPRI) to undertake a Strategic Analysis of the Global Status of CCS.
The analysis consisted of a comprehensive survey of all CCS projects being undertaken globally. CCS poses some major challenges, but with sustained long-term action, emissions reductions can be achieved at costs that are low in comparison to the risks of inaction. Costs could be even lower, if there are major gains in efficiency, or if the strong co-benefits, for example from reduced air pollution, are measured. However, costs will be higher if innovation in low carbon technologies is slower than expected. The future is uncertain, but an emerging certainty is the speed of change over the next decade.
At WorleyParsons we challenge ourselves to explore this change, and see a new environment emerging at both a regional and urban level.
