Novel dual-mixed refrigerant precooling process for high capacity hydrogen liquefaction plants with superior performance
(
Elsevier
, 2023 , Article)
Liquid hydrogen is a superior alternative for the current energy storage methods and energy carriers as it has higher energy density and cleanliness. However, hydrogen liquefaction is an energy-intensive process. In ...
Integrated novel solar distillation and solar single-effect absorption systems
(
Elsevier
, 2021 , Article)
Novel hybrid single-slope solar distillation systems integrated with single-effect solar absorption cooling system are designed, analyzed and optimized for production of cooling effect and freshwater, simultaneously. The ...
Novel integration between propane pre-cooled mixed refrigerant LNG process and concentrated solar power system based on supercritical CO2 power cycle
(
Elsevier
, 2023 , Article)
Liquefaction of natural gas (LNG) is an energy-intensive process with large CO2 emissions. This study addresses these problems by introducing a novel hybrid integration between the propane pre-cooled mixed-refrigerant ...
Theoretical and experimental study on the selection of pure and mixed refrigerants for a power-cooling system driven by ultra-low-grade heat
(
Elsevier
, 2023 , Article)
This study theoretically and experimentally evaluates the performance of a system that combines an organic Rankine cycle (ORC) and a vapor compression cycle (VCC) driven by ultra-low-grade heat (ULGH). A systematic method ...
A novel hydrogen liquefaction process using dual mixed cryogenic refrigeration system: Energy, exergy, and economic analysis
(
Elsevier
, 2024 , Article)
In conventional hydrogen liquefaction plants, the liquefaction process consumes high portion of about 30 % of the liquid hydrogen (LH2) energy content. In addition, existing LH2 technology uses pure or single mixed ...
Flare gas-to-power by direct intercooled oxy-combustion supercritical CO2 power cycles
(
Elsevier
, 2021 , Article)
With more than 150 billion m3 of gases annually flared around the world, gas flaring is a major source of greenhouse gas emissions that contaminates the environment with more than 400 Mt CO2/year. Therefore, utilizing the ...
Study of recirculating water-based and carbon-based working fluids on the combustion flow field and the cycle performances of semi-closed CO2-capturing Brayton-derived cycles
(
Elsevier
, 2022 , Article)
The transition into new power technologies that utilize fossil fuels with near zero emissions to the ambient is an urgent need to mitigate the worldwide environmental problems. In this study, detailed analyses of carbon-based ...
A combined thermo-mechanical refrigeration system with isobaric expander-compressor unit powered by low grade heat – Design and analysis
(
Elsevier
, 2020 , Article)
Refrigeration and air conditioning systems consume about 17% of the world-wide electricity and their conventional refrigerants cause ozone depletion and global warming. In this study a novel thermo-mechanical refrigeration ...
Techno-economic assessment of low-carbon hydrogen exports from the Middle East to the Asia-Pacific, and Europe
(
Taylor & Francis
, 2023 , Article)
Hydrogen has the potential to play a major role in the global energy mix in the future and to achieve carbon-neutral targets by 2050. However, there is a lack of studies that investigate the economic feasibility of ...
