Abstract null null Driven by climate mitigation goals countries around the world are prioritising low-cost renewables for economic growth and recovery from the aftermath of the global pandemic. It is quite clear that sustainable technology choices result in broader socioeconomic benefits, as is shown by countries that have been early movers in transitioning their energy sectors towards higher shares of renewables. There is growing interest in better understanding the direct impact on employment ...

Abstract null null Burning natural gas to heat water for oil sands separation is and energy and carbon-intensive process. This study presents a COMSOL Multiphysics simulation model that comprehensively investigates the feasibility of utilizing geothermal energy from enhanced geothermal systems (EGSs) as a heat source for oil sands separation. The simulation model was built with discrete fractures and was verified with analytical results. The results demonstrate that a doublet EGS performs better...

ABSTRACT null null In order to limit global warming of 1.5°C before 2050, the heat pump with waste heat recovery has been acknowledged as an effective technical solution. In this paper, a new kind of centrifugal heat pump system is applied to recover the waste heat from a steel plant for district heating. Two centrifugal compressors with vapor injection and two-cycle parallel connected system configuration are adopted to achieve higher energy efficiency and larger heating capacity. From simulati...
Abstract null null The coupling effect of subcritical water and FeCl3 on the extraction of bulk Huadian oil shale was experimentally investigated. The results showed that, with the addition of FeCl3, the yield of shale oil in subcritical water extraction was enhanced by 58.5 % at 20 h and the time required for the maximum shale oil production was reduced by 43 %. The group compositions of shale oil and residual bitumen as well as the elemental analysis of residual kerogen revealed that FeCl3 cou...
Abstract null null Extra moistures condensation and extraction from the boiler flue-gas have been proven to be an effective measure to enhance the thermal efficiency of the boiler system. Previous researches on the condensing flue-gas heat recovery unit was based on the controlled lab condition or instant site measurement which was unable to reflect the long-term real performance of the boiler system with flue-gas heat recovery units. This research employed the real-time measurement database est...

Abstract null null The trigeneration combined the electricity, cooling and heating makes adiabatic compressed air energy storage system (ACAES) popular as an energy storage technology. Based on thermodynamic analysis, this paper studies the influence on the system performance of four variable factors, including compression stages, expansion stages, water (heat storage medium) mass flow rates in charging process and discharging process to provide a guidance for the design of ACAES for different u...
Abstract null null This study proposes a highly reliable, robust, and accurate integrated framework to estimate the state-of-health (SOH) of lithium-ion batteries (LIBs), focusing on feature extraction and manipulation. This framework comprises three phases: feature extraction, feature manipulation, and SOH estimation. First, multiphysics features are extracted from mechanical and electrochemical evolutionary responses as distinct health indicators (HIs) to account for the multiphysics degradati...
