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 ↗739 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.

Physics-Informed Photovoltaic Fault Diagnosis Using Hard-Clamped Feature Engineering and Progressive Fine-Tuning ↗
Limited labeled fault data and discrepancies between simulated and measured signals complicate photovoltaic (PV) fault diagnosis. This study develops a transfer learning framework that combines hard-clamped electrical features with progressive fine-tuning. Four measured channels are expanded into a ten-dimensional (10D) representation containing power, an equivalent-resistance indicator, and consecutive-sample differences. A multi-scale convolutional neural network (MSCNN), bidirectional long short-term memory (BiLSTM), and self-attention form the sequence classifier. The model is pretrained o…

Flexible energy management of hybrid hydrogen-electric power system considering temperature-induced characteristics in unmanned aerial vehicle applications ↗
In hybrid hydrogen-electric unmanned aerial vehicle (UAV) applications, efficient energy management for the hybrid hydrogen-electric power system (HEPS) combining the hydrogen fuel cell (HFC) module with the lithium battery (LiBa) module is vitally important for the long-term and steady power supply. However, conventional energy management strategies (EMSs) generally assume a constant ambient temperature and employ fixed control thresholds for power allocation. This assumption is unsuitable for UAV missions involving rapid altitude changes, during which the time-varying ambient temperature alt…

Quantifying the Energy Performance of Biomimetic Façade Systems in Hot–Arid Residential Buildings: A Libyan Case Study ↗
Cooling demand in hot–arid regions motivates façades that regulate solar gain and airflow. This study quantifies biomimetic façade strategies for a Tripoli residence using DesignBuilder/EnergyPlus. The surveyed single-storey Utility-Calibrated Existing Bungalow (UCEB) recorded 14,161.000 kWh over one utility interval versus 14,161.048 kWh simulated (+0.000339%); this is an annual calibration check, not temporal or façade validation. A separate villa, B0, provides the comparative baseline (164.23 kWh/m2·year gross site EUI). P1, F1, S2, F3, P2 and P3 record 77.32, 51.63, 91.90, 50.02, 50.88 and…

Dual functional ligand for efficient and thermally stable perovskite absorber in hot carrier solar cells ↗
The practical implementation of hot-carrier solar cells requires absorber materials capable of simultaneously suppressing carrier thermalization and maintaining thermal stability under realistic operating conditions. However, the temperature dependence of thermalization losses in perovskite quantum dots remains largely unexplored. Here, isonicotinamide (IA) was employed as a dual-functional ligand to simultaneously passivate surface defects and enhance the thermal robustness of wide-bandgap CsPbI x Br 3-x quantum dots. By combining temperature- and power-dependent photoluminescence spectroscop…

Toward zero-shot generalization of deep reinforcement learning for hybrid energy system dispatch ↗
Hybrid energy system (HES) dispatch requires sequential operational decisions under uncertainty in renewable generation, demand, and market conditions. Deep reinforcement learning (DRL) is increasingly applied to this problem because it can learn dispatch policies from data without requiring full system models or future information. However, most existing studies train and evaluate DRL agents on the same environments, leaving their ability to generalize to unseen operating conditions largely untested. This study systematically investigates zero-shot generalization of DRL for HES dispatch. We p…

Decoupled DC-bus voltage regulation and adaptive energy management for fuel cell/battery/supercapacitor powered vehicle ↗
This paper presents a hierarchical energy management and control framework for a fuel cell–battery–supercapacitor hybrid electric vehicle with regulated DC-bus voltage. The proposed architecture decouples DC-bus voltage regulation from energy management by generating a net load current enabling flexible and constraint-aware power allocation among the energy sources. An adaptive frequency-based energy management strategy is developed, incorporating state-of-charge-dependent cutoff frequency and explicit battery availability logic to ensure safe operation under boundary conditions. Inner current…

A multiphysics framework for modeling expansion force during thermal runaway propagation in lithium-ion battery packs ↗
Early warning of thermal runaway is essential for ensuring the safety of lithium-ion batteries. Expansion force has emerged as an important early warning signal. Modeling cell expansion can provide critical insights into the underlying thermo-mechanical processes and offer a simulation tool for developing reliable warning strategies. However, existing models are generally limited to the single-cell level and lack dynamic coupling with TR propagation (TRP) in the battery pack. In this work, a multiphysics and multi-scale modeling framework is developed to capture the cell expansion behavior dur…

Effect of Chiral Arm Angle on the Stiffness, Auxeticity and Energy Absorption of Polyamide-12 Tetra-Chiral Lattices Under Quasi-Static Compression: A Numerical Baseline Study ↗
Chiral auxetic lattices convert axial loading into node rotation, producing negative Poisson’s ratios and high energy absorption. This purely numerical study establishes a quasi-static baseline for additively manufacturable polyamide-12 (PA12) tetra-chiral lattices in which the chiral arm angle (0–90°) is treated as a design variable; no experiments were performed, and the model is verified rather than validated. Geometrically non-linear elastoplastic finite element analyses with a data-sheet-derived bilinear PA12 card and frictional self-contact were carried to 20% nominal strain and supporte…

Load-Pressure-Based Source-Load-Matching Dynamic Pricing and Coordinated Optimization for Multi-Park Integrated Energy Systems ↗
Given that fixed energy tariffs and demand-response compensation rates cannot adequately capture temporal variations in source-load conditions across multi-park integrated energy systems, this study develops a coordinated optimization approach driven by load-pressure-based dynamic pricing. First, the original electric, thermal, and cooling load profiles are evaluated together with the day-ahead forecasts of wind and photovoltaic generation. These data are then converted into five pricing indicators: net electric load pressure, thermal load pressure, cooling load pressure, renewable energy outp…

Integrated Valorization of Plastic Waste into Synthetic Fuels and Electricity via Multi-Stage Upgrading: Process Modeling and Techno-Economic Analysis ↗
Abstract An integrated process for the valorization of 1000 kg/h of heterogeneous plastic waste (Plasmix) into hydrogen, purified CO2, light and heavy liquid fuels, and electricity was developed and simulated using Aspen Plus. The process combines non-catalytic pyrolysis with sequential syngas upgrading, tar catalytic conversion, and extensive heat integration to maximize product recovery and economic performance. In the pyrolysis stage (600 °C, 12 bar), Plasmix is efficiently converted into gas, tar, char, and wastewater, with the gaseous fraction representing the largest product share (42.1%…

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.
