This paper proposes a solar-assisted method for a petrochemical refinery, considering hydrogen production deployed in Yanbu, Saudi Arabia, as a case study to greenize oil refineries. . Rational allocation of energy storage capacity and optimization of corresponding subsidy policiesare crucial prerequisites for enhancing the economic viability and widespread adoption of photovoltaic energy storage integration projects. Mobile energy storage technologies for boosting carbon. Compared with traditional energy storage technologies, mobile energy storage technologies have. . Employing solar energy to drive crude oil refineries is one of the investigated pathways for using renewable energy sources to support lowering the carbon emissions and environmental impact of operating the processing of fossil-based fuels. Specifically, the analysis evaluates solar photovoltaics, wind turbines, battery energy. . This study aims to investigate a novel thermal design for an industrial heating process, study an integrated system of different components into overall plant, and incorporate solar energy in heating application and assess the key performance indicators of a crude oil refinery employing three. .
