In the continuing drive to meet the world’s future energy needs, few can have missed the increased recent prominence of unconventional hydrocarbons. The extraction of resources such as shale gas, using techniques like hydraulic fracturing (or fracking) has gained attention from around the world, both for its potential to fulfil our energy requirements, as well as due to concerns around possible environmental impacts.
Chemistry has a strong role to play in helping us to understand potential environmental impacts, particularly areas such as air and water quality. The Royal Society of Chemistry supports the research community examining these issues, as chemical sciences research can help to inform broader policy decisions on this issue. We publish papers and books across our portfolio of journals, including those that encourage scientific debate and have actively supported those in the research community to share knowledge and advance science. To mark the publication of a report that explores research questions in this area, we have gathered some of our best publications on this topic to share with readers.
Unconventional hydrocarbon extraction in different countries has evolved at different rates. In the US there has been rapid exploration that has led to commercial scale production, whilst in the UK we are at a much earlier stage of the debate. Examining the situation in places like the US, which has a comparatively more established shale gas industry, can help us to determine what is known about the potential environmental impacts and where research, including chemistry, can help to address unknowns.
In November 2015, the UK Natural Environment Research Council (NERC), the US National Science Foundation (NSF) and the Environment, Sustainability and Energy Division of the Royal Society of Chemistry brought together researchers from the US and the UK at a workshop on Improving the Understanding of the Potential Environmental Impacts Associated with Unconventional Hydrocarbons. The aim of the workshop was to share knowledge in this rapidly changing area, particularly with respect to identifying research gaps and areas where future research may be needed. The range of topics covered by the workshop was broad, including areas such as air quality and wastewater treatment, which have a direct link with the chemical sciences, through to seismicity and socioeconomic impacts.
Participants at the workshop had the opportunity to present current research in their field, taking into account the specific situation in their country. Discussions at the workshop examined similarities and differences between the different nations, leading onto the identification of knowledge gaps and future research needs.
The workshop’s co-chairs, Professor Richard Davies of Newcastle University and Professor Danny Reible at Texas Tech used the discussions from the meeting to produce a report, Joint US-UK Workshop on Improving the Understanding of the Potential Environmental Impacts Associated with Unconventional Hydrocarbons. The report captures key research gaps and needs in a whole range of areas from community engagement, to human health to waste water management.
Professor Richard Davies commented: “This workshop represented a valuable opportunity to prioritise and tailor research questions that could help us to better understand any potential environmental impacts if unconventional hydrocarbon extraction were to take place in the UK. The report examines both near-term and long-term research priorities for the research communities working in this area”.
The report will be relevant to researchers working on unconventional hydrocarbon extraction, outlining future research opportunities and needs. You can watch Professor Fred Worrall, one of the UK workshop participants talk about some of the points covered at the workshop in his lecture Exploring the impact of the unknown: a potential UK shale gas industry. Fred’s work on monitoring emissions relating to onshore oil and gas operations is also the subject of a recent Education in Chemistry article.
We hope that you will enjoy reading about both recent research advances and future areas for investigation in an area that will likely continue to feature in both scientific and public discourse.
