Abstract

Ukraine’s energy economy is largely served by natural gas imported from Russia, even though coal is

the country’s richest resource of fossil fuels. Within the power generating sector, nuclear power’s role

is expected to increase in the future. The country’s 60 Mt/y coal industry, mostly bituminous and

anthracite, has recently undergone a programme of changes, including mine privatisation, closing of

Abstract

This report discusses the current status of utilisation of low quality coals worldwide. The largest

market for low quality coals is power generation. Power generation using low quality coals is

dominated by Pulverised Coal Combustion (PCC) plants. Although the majority of PCC plants uses

subcritical technologies, a number of new plants have adopted supercritical steam conditions at large

Abstract

This report provides a review of the Chinese energy security concerns, since imports are providing an

ever increasing proportion of the oil and gas used compared to domestic supplies. Due to the relative

paucity of Chinese oil and gas reserves, the government has adopted a policy of diversification by

securing supplies via overland pipelines and by tankers from various sources. At the same time, due to

Abstract

This report examines the global situation with regard to the scale, location and major uses of low

quality coals and addresses the individual countries where they currently play, or in the future, are

likely to play, an important role in energy production.

 

Around half of the world’s estimated recoverable coal reserves comprise low value coals,

Abstract

In 1998, a colleague introduced a paper on greenhouse gas (GHG) reduction with a famous Mark

Twain quote: ‘Everybody talks about the weather, but nobody does anything about it.’ Humour aside,

the colleague’s point was to highlight the considerable body of work under way to develop

technologies to address the climate change impacts of GHG emissions. One option is carbon capture

Abstract

Chemical looping combustion is an indirect form of combustion in which an oxygen-containing solid material, typically a metal

oxide, supplies the oxygen to a fuel, and the spent oxygen ‘carrier’ is separately regenerated by high temperature reaction in an air

stream. As there is no direct contact between air and fuel, CO2 recovery up to very high levels is simplified. There is also potential

Abstract

Whenever coal is burnt, ash is produced by the thermal transformation of the mineral matter present. Large-scale uses of coal,

such as power generation, give rise to significant quantities of ash and a number of uses for this by-product have been developed

over time.

 

During the last two decades a number of changes have occurred in the coal-fired power generation sector that have affected ash

Abstract

The practice of cofiring biomass in full-scale coal utility plants is increasing, due to the benefits of reduced fossil fuel based CO2

emissions. Biomass also tends to have a lower sulphur content than coal and therefore emissions of SO2 can be reduced. The same

is true for NOx emissions from lower fuel nitrogen content. Further, the lower flame temperatures and different combustion

Microbial methane from carbon dioxide in coal beds, CCC/174

Abstract

Microbial CH4 chemistry and its formation in coal are summarised. The results of recent research on microbial CH4 formation are

reviewed from Australia, China, Germany, Japan, and the USA. Two fields of interest are considered in this report. Enhanced
