Webinars

At IEA Clean Coal Centre webinars our expert authors give presentations on the findings of their latest reports. Webinars usually take place on the second Wednesday of the month at midday (UK Time). If you are unable to attend the event live, they can be viewed at any time after the event from this page.

The first Asia-Pacific webinar from the IEA CCC takes place on 24 April. Toby Lockwood and Kyle Nicol will give a presentation from Melbourne, Australia at 2 pm (Australian time, 5 am UK time). The focus of the webinar will be on Toby's study  of recent developments in oxy-combustion technology.Kyle will reprise briefly his report on high temperature steels for pulverised coal technology.

In oxyfuel combustion, coal is fired in a mixture of oxygen and recycled flue gases to produce a concentrated stream of CO2 which can be purified for sequestration without the use of absorption solvents. Despite the successful operation of Vattenfall’s 30 MWt pilot plant since 2009, oxyfuel capture has yet to progress to the demonstration phase. However, the recent commissioning of a 100 MWt retrofit project and a 30 MWt oxyfuel circulating fluidised bed represent major steps for the technology. A number of new demonstration projects have also progressed to advanced stages of planning, of which the 167 MW FutureGen 2.0 plant could commence construction this year. With operation at the pilot-scale well-established, ongoing oxyfuel research has focussed on clarifying the complex effect of the altered gas composition on combustion, heat transfer, and corrosion mechanisms in the boiler. As overall plant efficiency is limited by the substantial auxiliary loads required for oxygen production and purification of the CO2 product, optimisation of these processes is also key to future scale-up. Commercial cryogenic air separation units can be thermally integrated with the plant’s steam cycle for higher efficiencies, or potentially replaced by membrane-based processes currently in early stages of development. New technologies trialled for CO2 purification have focussed primarily on improving SOx and NOx removal and achieving almost complete CO2 capture. This report will review technological progress in each element of the oxyfuel plant, as well as presenting the latest results from large pilot projects and demonstration FEED studies. Finally, recent analyses of the potential efficiency and economic performance of future commercial-scale plant are compared.
