2-2-2-2-2-2-2-2-2-2-2-2-2 From: Isabelle Chambefort <I.Chambefort@xxxxxxxxxx> We are inviting to submit abstracts to the following IAVCEI 2023 sessions under the theme "Volcanoes, energy, resources and environment" in Rotorua 30 Jan - 3 Feb 2023. The organisation of the IAVCEI conference in Rotorua New Zealand is a great opportunity to discover and share about geothermal energy and benefit to the scientific and public communities. *Characterizing geothermal activities in volcanic settings*Anya Seward, Nicole Lautze, Shaul Hurwitz, Cary Lindsay, Isabelle Chambefort *Outline* Many magmatic systems have the potential to provide a sustainable source of geothermal energy, a clean, low-carbon footprint, and cost-effective source of renewable energy. Economic extraction of geothermal heat in these systems depends on a combination of variables that include water recharge, reservoir permeability and access to the heat source. Characterizing and quantifying the interplay between these variables is essential for geothermal energy development and sustainability. While providing a sustainable source of energy, heat extraction in geothermal systems must include mitigation of potential environmental impacts and risk assessments associated with geothermal plant operations. This session will cover a broad range of topics, including, but not limited to, techniques used to characterize and quantify geothermal resources, models of heat and mass transfer, spatial and temporal characteristics of reservoir permeability, delineation of geological structures, resource management, environmental and/or societal impacts, direct geothermal use, community outreach and hazards associated with geothermal energy production. The goal of this session is to bring together scientists from a range of disciplines (e.g. geology, geophysics, geochemistry, numerical modelling and resource management) to discuss challenges to, and/or advancements in, process-based understanding, technologies, resource management and sustainability of geothermal systems. *Harvesting energy from magma â?? the future of supercritical geothermal resources*Dr Isabelle Chambefort, Prof Thomas Driesner, Prof Andri Stefánsson, Dr.-Ing. Thomas Reinsch, Prof John Eichelberger *Outline* Worldwide research endeavours are exploring the potential for targeting and harvesting geothermal energy from greater depths and temperatures. Volcanic provinces offer the greatest potential to encounter unconventional geothermal resources where temperature or temperature and pressure conditions exceed the critical point of water (supercritical fluids) at shallow depth in the Earthâ??s crust as evidenced in several active geothermal systems worldwide including Krafla, Nesjavellir and Reykjanes (Iceland), The Geysers and Hawaii (USA), Lardarello (Italy), Los Humeros (Mexico), Menengai (Kenya), Kakkonda (Japan). These resources could generate an order of magnitude more energy per well than from conventional geothermal reservoirs. While some current projects focus on utilizing supercritical fluids some others explore the possibility of drilling into magma directly. In this session we are welcoming abstracts looking at increasing scientific knowledge of the magmatic-hydrothermal transition in order to better understand future geothermal resources as well as magmatic and hydrothermal processes. 2-2-2-2-2-2-2-2-2-2-2-2-2 ------------------------------
