Clean power generation from the intractable coalfield fires: turning harm into benefit

Overview

Energy production is generally seen as the conversion of a specific resource into usable energy. Ideally, the resource is renewable and the conversion process is free from undesirable by-products’. Nevertheless, this is normally not the case and non-renewable resources and waste seem to always be present either during the manufacture of the conversion system, the actual energy generation, or in the construction of energy storage devices. Thus, energy production always requires a cost-benefit analysis. 

The approach that sees energy production as a cost-benefit analysis enables concepts such as ‘waste to energy’ or ‘resource recovery.’ A powerful example of ‘resource recovery’ pertains to the unusual phenomenon of underground fires. Underground fires represent a massive and uncontrolled energy release that is not utilized, is very difficult to suppress and is a major source of greenhouse gas emissions.

Extracting energy while systemically suppressing these fires is a major technological challenge, but has the potential for significant benefit. At the heart of this technological challenge is the understanding of smouldering combustion.

This presentation discusses the fundamentals of energy recovery from underground fires as well as providing a series of examples of how smouldering combustion has been used effectively for resource recovery.

After the lecture, there will be a networking drinks reception. A £10 contribution is required to attend the lecture and this will include the wine reception. If you would like to participate in these events, please proceed by using the 'book now' button which will enable you to register your interest by emailing [email protected] and you'll be provided with the payment details.  Otherwise, payment can be made by cash or card during your attendance.
