Earlier sources: Geothermal
This energy thread follows geothermal through original research, public projects, and source reports. Read the evidence below to see which developments are represented in SYMTRI’s archive.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗8 classified signals in the fourteen-day window. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

From parameter coupling to constraint-aware optimization: Geothermal organic flash cycles with reinjection and pinch-point limits ↗
Organic flash cycles (OFCs) improve temperature matching between the geothermal brine and the working fluids, but their practical design is constrained by site-dependent reinjection temperature and heat exchanger pinch limits. This study compares a basic OFC (BOFC) and a modified OFC (MOFC) to determine how the primary heat exchanger (PHE) outlet temperature, flash temperature, brine reinjection temperature, and PHE pinch-point temperature difference (PPTD) govern the feasible regions and thermo-economic performance. A segmented PHE model enforces the pinch constraints, a Sobol analysis quanti…

Permeability Evolution and Heat Extraction in Superhot and Supercritical Geothermal Systems: From Brittle–Ductile Mechanics to Long-Term Reservoir Performance ↗
Superhot and supercritical geothermal resources provide higher-enthalpy fluids than conventional systems. Their feasibility, however, depends on a connected flow system that survives extreme temperature, pressure, stress, and fluid chemistry. This critical narrative review evaluates field, laboratory, and numerical evidence for the creation, evolution, and management of permeability. It distinguishes superhot rock from supercritical fluid. The latter requires temperature, pressure, and composition to be evaluated together. Kakkonda and the Iceland Deep Drilling Project (IDDP) demonstrate acces…

Theory, technologies, and practice of oilfield-geothermal co-development in the Bohai Bay Basin ↗
Abstract Driven by the global energy transition and China's dual-carbon goals, oil and gas field development faces challenges in achieving sustainable development. Oilfield-geothermal co-development (OGC) offers a pathway for revitalizing mature oilfields and supplying low-carbon energy. This article describes the resource endowment, genetic mechanisms, and oil-heat-water co-occurrence relationships of geothermal resources in oilfields, examines the theory and key technologies for OGC, and proposes an integrated technical system. Development modes include waste-heat recovery from produced flui…

Unlocking Low-Carbon Heat: Geothermal Feasibility and Thermal Breakthrough in Carboniferous Sandstone Aquifers ↗
Decarbonisation is crucial for mitigating climate change, with ground source heat pumps (GSHPs) playing a key role in reducing reliance on gas for space heating. This study investigates the potential of an open-loop GSHP system in the Carboniferous Millstone Grit of Ilkley, West Yorkshire, using Ilkley Lido and surrounding sports facilities as an example heating demand. The feasibility of systems installed at depths less than 150 m is examined, considering both shallow and deeper geological conditions. Available data on subsurface geology, hydrogeology, and geothermal gradients are utilised to…

SiO2-Amine Materials from Geothermal Silica Waste with Potential Application in Direct CO2 Air Capture ↗
Abstract Direct CO2 air capture (DAC) has become a key strategy for tackling climate change, as it can help reduce the concentration of this greenhouse gas (GHG) in the atmosphere, which, as of July 2026, has risen to 429.12 ppm. Most DAC techniques are based on adsorption processes, in which sorbents must have high adsorption capacity, good selectivity, easy regeneration, low energy penalty, suitable adsorption–desorption kinetics, excellent chemical stability, and low cost. Amine functionalization of porous materials has been proposed to improve CO2 adsorption capacity and selectivity, and u…

Simulator‐Based Bayesian Inference of Enhanced Geothermal Reservoir Properties ↗
Abstract Inversions of dynamic multi‐scale multi‐physics subsurface system properties rely on the effective sampling of high‐dimensional parameter spaces and are thus notoriously difficult to perform. The associated models are defined by complex nonlinear relationships with potentially stochastic components, which lead to analytically intractable likelihoods that require challenging forward simulations of the system response. This paper presents the application of the Bayesian optimization for likelihood‐free inference (BOLFI) algorithm to invert the properties of a geothermal reservoir. We us…

A Fast Random-Feature Surrogate for Geothermal Heat-Transport Prediction and Breakthrough Risk Screening ↗
Repeated geothermal evaluation motivates inexpensive flow and heat-transport approximations. We combine proper orthogonal decomposition (POD) with extreme learning machine (ELM) regression to reconstruct temperature fields and predict production curves and horizon-capped breakthrough times from simulation data. A manufactured elliptic benchmark examines spectral residuals; a conditional one-dimensional bound distinguishes approximation, interpolation, and regularization under assumed discrete stability. In the synthetic early-time case, the mean relative field-trajectory reconstruction error i…

Transient Responses of Avian Assemblages to Geothermal Drilling in Costa Rica ↗
Due to their requirements, geothermal projects are often located near volcanic activity that, in the tropics, overlaps with or lies close to conservation areas. It is therefore important to assess the environmental impact of these projects on biodiversity. We evaluated the impacts of well-drilling activities on bird communities at a geothermal field in Costa Rica. We hypothesized that (i) disturbance generated during drilling caused a temporary decline in bird diversity and abundance, followed by recovery once drilling noise ceased, and (ii) responses were species-specific, ranging from a nega…

How to assess evidence about Geothermal
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
