Hawaii's geothermal and deep water cable programs

open access: yes, 1985
"Hawaii's dependence on imported fuel oil for over 90 percent of its energy needs can be minimized by exploitation of the State's abundant indigenous energy resources.

Are SMEs Claiming to Be Circular, Actually Circular? An Empirical Study on the Implementation and Performance Evaluation of Circular Economy Practices

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The circular economy is a key paradigm for ecological and ethical transition, particularly in the manufacturing sector. Although small and medium‐sized enterprises are pivotal in advancing the circular economy, the implementation of circular economy practices remains limited, with a focus on less impactful practices such as recycling and ...

Measuring Corporate Energy Transition Through Web‐Based Evidence and Large Language Models

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper proposes a scalable method to measure firm‐level engagement with the energy transition using corporate website disclosures and large language models (LLMs). We construct a restrictive, policy‐aligned rubric that codes evidence of (i) energy efficiency improvements, (ii) decarbonization and emissions‐reduction strategies, and (iii ...

Hierarchically Engineered Transition Metal Electrode for Direct Lithium Extraction From Brine

open access: yesCarbon Energy, EarlyView.
Carbon‐modified WO3 nanoparticles deliver lithium extraction from simulated brine with Li+ capacity of 3 mmol Li g−1h−1 and 43% recovery efficiency. Reduced graphene oxide enhances charge transport and interfacial stability, while reversible W redox validated by in‐situ spectroscopy, governs lithium intercalation dynamics and structural stability ...

Gibbs energy minimization thermodynamics for CO2 capture by aqueous amines: Conservation laws, concentration variables, and parameter consistency

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
We clarify how Gibbs‐energy‐minimization models for aqueous‐amine CO2 capture fail when conservation constraints and concentration conventions are inconsistent. Exact standard‐state conversions and Reaktoro case studies show that P(CO2)‐loading fits can mask non‐unique parameters and wrong speciation, motivating complete water‐inclusive formulations ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

open access: yesDeep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

open access: yesDeep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

open access: yesDeep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.
