Earlier sources: Energy
Energy research and engineering concern how power is produced, stored, delivered, and consumed. Follow solar and nuclear power, fusion, geothermal systems, batteries, electricity grids, and changing power demand.
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 ↗755 classified signals in the fourteen-day window. Recent momentum: steady. 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.

A Simplified Multi-Objective Optimization Method for Building Energy Design Under Present and Future Climate Scenarios ↗
Climate change poses significant challenges for building energy retrofit, as solutions optimized for present-day conditions may become suboptimal under future climates. Although multi-objective optimization is an effective approach for identifying retrofit strategies, incorporating both present and future scenarios substantially increases computational cost. This study proposes a simplified multi-objective optimization method in which the genetic-algorithm search is performed only once, under present-day weather; the resulting Pareto-optimal solutions are then re-simulated under four future IP…

Finite-Time Sliding Mode Control of an LCC-S-Based Wireless-Power-Transfer-Enabled Hybrid Energy-Storage System for Fuel Cell Electric Vehicles ↗
The integration of wireless power transfer (WPT) technology with fuel cell hybrid electric vehicles (FCHEVs) offers a viable solution to enhance energy accessibility, increase flexibility, and improve driving sustainability. However, the coordinated operation of wireless charging systems, hybrid energy-storage systems (HESSs), and vehicular propulsion units introduces significant control challenges due to nonlinear dynamics, parameter uncertainties, and rapidly varying load demands. To overcome these limitations, this paper presents a WPT–FCHEV architecture comprising an LCC-S-based wireless c…

Nanotechnology‐Driven Analysis of MHD Maxwell‐Casson Nanofluid Flow With Activation Energy Using Artificial Neural Networks ↗
ABSTRACT The Maxwell‐Casson nanofluid (NF) flow past a porous inclined plate has attracted much attention, since it has extensive potential applications in thermal energy systems, chemical processes, biomedical transport, and advanced cooling technology. This paper aims to simulate the flow and heat and mass transfer (HMT) characteristics of Maxwell‐Casson NF past an inclined porous plate under the influence of a magnetic field, Darcy‐Forchheimer porous resistance, thermal radiation, and a chemical reaction with activation energy. A Casson parameter is included in the mathematical modeling for…

Simultaneous seismic mitigation and harvesting performance of an electromagnetic energy-harvesting nonlinear energy sink ↗
A novel electromagnetic energy-harvesting nonlinear energy sink (EH-NES) is proposed for simultaneous vibration mitigation and energy harvesting. Considering parasitic effects, shaking table tests are conducted to examine the device performance, followed by parameter identification. Numerical models are validated in terms of both mechanical and electrical responses, followed by parametric studies to quantify the impact of critical parameters on the dual-functional performance. Moreover, seismic robustness analyses evaluate the potential of the EH-NES for synchronized vibration mitigation and e…

Symmetry-Preserving Clustering and Coordinated Control for Voltage Fluctuation Mitigation and Stability Enhancement in Active Distribution Networks with SoC Balancing of Battery Energy Storage ↗
High penetration of distributed renewable generation in active distribution networks frequently leads to severe voltage fluctuations and challenges system voltage stability, as the inherent power-flow symmetry is disrupted by stochastic and bidirectional power injections. To address these issues, this paper proposes a symmetry-preserving coordinated control strategy that integrates topology-constrained clustering with state-of-charge (SoC) balancing of battery energy storage systems to actively mitigate voltage fluctuations and enhance operational stability. First, an agglomerative hierarchica…

Intelligent forecasting of photovoltaic power output using integrated meteorological and operational data ↗
Background Integrating solar energy into smart grids necessitates accurate forecasting models to ensure grid stability and efficient energy management. Traditional methods struggle with weather-induced fluctuations and system-specific variations, while existing data-driven approaches fail to capture the nonlinear relationships between meteorological conditions and photovoltaic (PV) operational parameters. Results We propose the Spectral-Aware Photovoltaic Encoder (SAPE), a physics-informed deep learning framework that integrates wavelength-resolved irradiance modeling with real-time operationa…

Experimental investigation on a passive photovoltaic evaporative cooling system based on dual-scale capillary aluminum fins ↗
Heat accumulation in photovoltaic modules during operation significantly degrades their efficiency and lifespan. Developing efficient passive phase-change thermal management is key to overcoming this limitation. However, existing solutions lack cooling stability under high heat fluxes and humid environments. Here, we propose and fabricate a Capillary Evaporative Finned Heat Sink (CEFHS) with a dual-scale microgroove structure. Using optical and infrared dual-modal imaging, we analyze its liquid transport and capillary performance, and evaluate its heat transfer and Photovoltaic (PV) cooling un…

Identifying people’s energy information needs through Energy Citizen Personas ↗
Energy Citizenship refers to individuals and communities participating, sometimes begrudgingly, in adopting energy solutions, whether sustainable or not. When enacted positively, it advances the green energy transition. There are several pathways for citizens to participate in the green energy transition; however, participation should be voluntary and compatible with citizens’ life contexts. Energy information is vital in enabling people to get involved in the green energy transition. However, less is known about how the energy information needs of citizens vary with their lifestyle and contex…

Optimization of spectral photon-counting CT reconstruction parameters for improved detection of peritoneal metastases compared with energy-integrating detector dual-energy CT: a phantom study ↗
Abstract Objective To determine the best combination of reconstruction parameters on a spectral photon-counting CT (SPCCT) system to improve detection of peritoneal metastases (PMs) on virtual monoenergetic images (VMIs) at 40 keV. Materials and methods A spectral phantom was scanned using SPCCT and dual-energy CT (EID-DECT) at 8.5 mGy (CTDI vol ). 40 keV VMIs were reconstructed on EID-DECT using a level 4 Spectral algorithm and kernel B. For SPCCT, two reconstruction kernels (STD-B and HRB) and four iDose 4 levels (i5/i7/i9/i11) were used. Noise power spectrum (NPS) and task-based transfer fu…

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…

How to assess evidence about Energy
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.
