Arnaud Mignan’s Post

If you asked my parents what my PhD research is about, guaranteed their answer would be "oh I'm not sure, something to do with hot rocks" … I've told them countless times over the dinner table 🙃   Recently, I wrote an article describing my research at an introductory level and why it's important, specifically across UK and Ireland. Hopefully this blog gives some insight into the significance of exploring geothermal reservoirs (and will help my parents understand what I do!)

Will we see you there? There's still time to book, details in the link below!

The development of #offshore wind farms plays a key role in the transition to #renewable energy sources. This requires reliable ground models, which are currently only available to a limited extent. The correct integration and correlation of geotechnical and geophysical data is a key factor in the creation of reliable ground models. This study investigates different prediction methods, while presenting a modelling framework which incorporates geological, geotechnical, and geophysical information to derive synthetic Cone Penetration Testing (CPT) profiles using offshore wind farm site investigation data from the German North Sea. Seismic attributes are used as auxiliary information to improve CPT parameter prediction. The results indicate a reduction of prediction uncertainty when implementing seismic attributes.

The scientific research organisation has installed a new #lowcarbon heating system and will monitor benefits in real-time, producing significant data for others to learn from. A geothermal #heatpump has been installed at the headquarters of the British Geological Survey (#BGS) in Keyworth, #Nottinghamshire. Costing £1.7million, the project has been majority funded by the Natural Environmental Research Council (#NERC) and the UK Government’s Public Sector Decarbonisation Scheme. The technology comprises an array of 28 boreholes drilled to a depth of 225metres, and will replace old gas boilers. Once fully operational, the system will heat two buildings at the site, where 400 people work, cutting #carbondioxide equivalent emissions by around 30 tonnes per year, helping bring down the organisation’s heating bill and #greenhousegas #footprint. This is part of a wider effort to bring down emissions, with 1000 #solarpanels already fitted above the BGS parking area in 2022. A ‘living laboratory’ is also factored into the plans, with state-of-the-art sensors installed within heat extraction boreholes and buildings, providing data in real time to help improve understandings of ground source heat systems, and #decarbonisation. Rock samples will also be taken to increase knowledge of water and heat flow underground, with the local geology comparable to a large proportion of the #UK, meaning lessons learned here can be applied to other parts of the country. ‘Geothermal energy is heat that naturally occurs under the ground and is available 24/7 across the UK. This project will demonstrate the deployment of ground-source heat pump technology to decarbonise existing buildings across the public sector estate,’ said David Boon, a BGS Senior Engineering and Geothermal Geologist. ‘This exciting project gives us the opportunity to blend our observation of the subsurface with leading low-carbon heating,’ said Daniel Crow, head of BGS estates and facilities. ‘The disruption to BGS staff will be kept to a minimum, with short closures of a couple of buildings to allow for the installation of heat emitters. The drilling and heat pump installation is due to last around three months. The borehole installation should not impact on Keyworth site operations due to the careful planning and specification involved in the project.’

We recently interviewed Geothermal Evangelist Malcolm Ross ahead of his upcoming GeoLogica course. Malcolm tells us about his career evolution from flow modeling, all the way through innovation and into geothermal. He also shares his insights about what the challenges are for the geothermal industry. Read the full article here: https://lnkd.in/ehfMPr3x #geothermal #geosciencetraining #energytransition

The National Energy Technology Laboratory, part of the U.S. Department of Energy (DOE), has released a study on improving #carbonstorage. The researchers set out to address risks associated with multiple #carbonsequestration wells located in close proximity to each other. Specifically, concerns over caprock integrity associated with reservoir pressure buildup and the likelihood of it interfering with adjacent sequestration projects. The comprehensive 22 page study concludes that injecting #CO2 into a stacked sequence of geological formations reduces basin pressure by 40%+. #energytransition #IRA #carbon #decarbonization #decarbonisation #carboncapture #ccs #ccus #carbonremoval #DAC #directaircapture #oilandgas

I talked with Samo Burja about the ideas in his recent article “Geothermal Energy Turns Planets Into Power Sources.” We discussed the heat beneath the earth’s surface, contributors to the heat, technological dependency between fracking & geothermal, the math of electricity, earthquake risk, the limits of current geology, the value of better drilling tech, new approaches to drilling, gyrotrons, plasma torches, whether our civilization actually needs more energy, the local optimum of fossil fuels, bureaucratic incentives in energy, investment of social surplus, scientific welfare, metascience, giving academic tenure to brilliant 25-year-olds, a defense-favoring military epoch, the math of geothermal vs other combinations of energy sources, visions of a clean-energy future, and much more.

Green transition 😊 - makes the subsurface, subsurface spatial planning, sustainable management of competing uses of the surface and subsurface and a Geological Service for Europe more important than ever

Very nice breakdown of potential plays for natural hydrogen. A lot to dig into here, would be great to see more of the backup research, but this gives you an idea of the many areas still being explored for natural hydrogen. I still expect the initial find to be based on traditional models explorers are using now with a sedimentary trap and serpentinization as the origin. Expect a few surprises as explorers and researchers take a wider look. There is a lot more going on in the study and ideas in this than people realize. #NaturalHydrogen #WhiteHydrogen #GeologicHydrogen
