Electricity Generation in Saudi Arabia: Tracing Opportunities and Challenges to Reducing Greenhouse Gas Emissions

Abstract

The electrical energy demand of the Kingdom of Saudi Arabia (KSA) has been observing a surging growth due to high population growth and urbanization rate. The generation mostly comes from the burning of petroleum products. The electricity sector emits more than one-third of the national greenhouse gas (GHG) of the country. Thus, it is essential to reduce the GHG from the electricity generation sector to maintain sustainability. This article mainly concentrates on the existing electricity generation and focuses on the Kingdom's GHG emissions mitigation initiatives. Although the use of natural gas and the number of cogeneration plants have been increased in electricity generation, the country has also been focusing on other initiatives, including the adaptation of combined cycle power plants, carbon capture, utilization, and sequestration (CCUS), renewable and alternative energy sources, and various utility-scale energy efficiency measures. The ambitious and inspirational renewable energy (RE) targets of the Saudi Vision 2030 will significantly facilitate GHG emission avoidance, which will support the Kingdom to meet its Nationally Determined Contributions. This article recommends various mitigation measures, including the usage of the efficient internal combustion engine, poly-generation, combined heat and power (CHP) systems, deployment of renewable resources in the distribution and microgrid systems, bio-mass engine, and ocean thermal energy conversion plants. The decision-makers and the researchers will find the discussions and recommendations helpful in determining suitable and appropriate mitigation initiatives and technologies.INDEX TERMS Carbon capture, climate change mitigation, electricity generation, greenhouse gas emissions, Kingdom of Saudi Arabia, renewable energy, review.

“…These factors have a direct impact on the performance of solar power plants: average temperature (C1), solar radiation (C2), land aspects and slope (C3 and C4), urban vicinity (C5), highway proximity (C6), and power line proximity (C7). As part of Saudi Vision 2030, the country aims to generate 58.7 gigawatts of renewable energy resources by 2030 [78].…”

“…Due to a rise in energy production demand, pressure is mounting on fossil fuel reserves alongside an increase in the emission of the greenhouse gas CO 2 [14]. As energy production and consumption continue to rise, it is imperative to identify viable, sustainable, and ecologically friendly energy alternatives [10,15,16]. Therefore, carbon-neutral, sustainable, and renewable energy sources that do not contribute to the overall output of CO 2 are required.…”
