1.1 Introduction
Natural Gas is a fossil fuel consisting primarily of methane (CH4), natural gas is used extensively for electricity generation, heating, and industrial processes. It is considered a cleaner alternative to other fossil fuels due to its lower carbon dioxide emissions when burned (EIA, 2020). Natural gas is a vital component of the global energy mix, playing a crucial role in powering industries, heating homes, and generating electricity. As the world shifts towards more sustainable energy solutions, optimizing the utilization of natural gas becomes increasingly important. This research aims to explore and enhance strategies for using natural gas more efficiently and sustainably. One of the primary drivers for optimizing natural gas utilization is the need to reduce greenhouse gas emissions. Natural gas, being the cleanest of the fossil fuels, produces significantly lower carbon dioxide emissions compared to coal and oil when combusted for energy.
According to the International Energy Agency (IEA), addressing these leaks could cut global methane emissions by 75% using existing technologies (IEA, 2022). Advancements in technology offer promising solutions for optimizing natural gas usage. Innovations in carbon capture and storage and the development of natural gas infrastructure, such as pipelines and storage facilities, are essential for enhancing efficiency and reducing environmental impact. Moreover, integrating renewable energy sources with natural gas systems can further improve sustainability. The United States Environmental Protection Agency highlights that combining natural gas with renewable energy sources can provide a reliable and cleaner energy supply (EPA, 2021).

1.2 Background of Study
The 1970s energy crises marked a pivotal moment in the history of natural gas utilization. In response to oil shortages and price spikes, many countries began to diversify their energy portfolios, increasing their reliance on natural gas. During this period, technological advancements such as the development of liquefied natural gas (LNG) technologies allowed natural gas to be transported internationally, further integrating global energy markets (Stern, 2019). The late 20th and early 21st centuries saw the advent of hydraulic fracturing and horizontal drilling, revolutionizing the natural gas industry. These technologies unlocked vast shale gas reserves, particularly in North America, leading to a dramatic increase in natural gas production. The "shale revolution" not only enhanced energy security by reducing dependence on imported oil but also contributed to lower greenhouse gas emissions by displacing coal in electricity generation (EIA, 2020).
In recent decades, the focus has increasingly shifted towards optimizing the environmental performance of natural gas utilization. Methane emissions, a potent greenhouse gas, have become a significant concern. Efforts to detect and mitigate methane leaks across the natural gas supply chain have intensified, driven by both regulatory pressures and industry initiatives. The Global Methane Pledge, launched in 2021, exemplifies international efforts to reduce methane emissions by 30% from 2020 levels by 2030 (Global Methane Pledge, 2021). Technological innovations continue to play a crucial role in optimizing natural gas utilization. Carbon capture and storage (CCS) technologies, for example, are being developed to reduce carbon emissions from natural gas-fired power plants and industrial processes. Additionally, the integration of natural gas with renewable energy systems, such as using natural gas power plants to provide backup for intermittent renewable sources like wind and solar, is an emerging strategy to enhance grid reliability and reduce overall emissions (IEA, 2021).
The utilization of natural gas has undergone significant evolution over the past few decades, driven by advancements in extraction technologies, market dynamics, and environmental policies. Historically, natural gas was primarily a byproduct of oil extraction and often flared or vented due to the lack of infrastructure and market demand. However, the rise of technologies such as hydraulic fracturing and horizontal drilling has unlocked vast reserves of natural gas, particularly in regions like North America, leading to a boom in production and a shift in global energy landscapes (EIA, 2020). One of the pivotal aspects of natural gas utilization is its role in reducing greenhouse gas emissions. As the cleanest burning fossil fuel, natural gas produces about half the carbon dioxide emissions of coal and a fraction of the sulfur dioxide and nitrogen oxides. This makes it a more environmentally friendly option for electricity generation and industrial processes. The transition from coal to natural gas in power plants has been a major factor in the reduction of carbon emissions in countries like the United States (IEA, 2019).
According to Global Methane Initiative (2021), natural gas industry faces several challenges that necessitate the optimization of its utilization. Methane emissions, which are significantly more potent than carbon dioxide in terms of their greenhouse effect, pose a substantial environmental concern. The Global Methane Initiative reports that the oil and gas sector is one of the largest anthropogenic sources of methane emissions, and mitigating these emissions is crucial for achieving climate targets (Global Methane Initiative, 2021). Technological advancements offer promising pathways for optimizing natural gas utilization. Carbon capture and storage (CCS) technologies, for instance, can significantly reduce emissions from natural gas-fired power plants and industrial facilities. Additionally, improvements in pipeline infrastructure and storage capabilities enhance the efficiency and reliability of natural gas supply chains. The integration of renewable energy sources with natural gas systems also presents a viable strategy for balancing intermittent renewable energy production and ensuring a steady energy supply (EPA, 2021).
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the optimization of strategies for natural gas utilization.
1.3 Statement of Problems
Investigation revealed that the optimization of strategies for natural gas utilization faces several critical challenges that need to be addressed to ensure its sustainable and efficient use. One of the foremost issues is the environmental impact associated with methane emissions. Methane, a potent greenhouse gas, has a global warming potential many times greater than carbon dioxide over a 20-year period. Despite natural gas being a cleaner alternative to other fossil fuels, methane leaks during extraction, transportation, and storage significantly undermine its environmental benefits (EPA, 2021). Another significant problem is the inefficiency in current natural gas infrastructure. Aging pipelines, inadequate storage facilities, and limited access to advanced technologies result in substantial energy losses and increased operational costs. These inefficiencies not only affect the economic viability of natural gas projects but also contribute to higher emissions and energy waste (IEA, 2021).
The integration of natural gas with renewable energy sources presents another set of challenges. While natural gas can complement intermittent renewable energy sources like wind and solar, the lack of optimized systems for seamless integration leads to underutilization and inefficiencies. Developing robust systems that can efficiently balance the supply and demand of energy from these mixed sources remains a complex task (IEA, 2021). Economic factors also play a crucial role in the optimization of natural gas utilization. Fluctuating natural gas prices, influenced by global market dynamics and geopolitical tensions, create uncertainty for both producers and consumers. This volatility can hinder long-term planning and investment in infrastructure and technologies necessary for optimizing natural gas use (EIA, 2020).
Additionally, regulatory and policy frameworks often lag behind technological advancements. Inconsistent regulations and policies across different regions can impede the implementation of best practices and innovations in the natural gas sector. Harmonizing these frameworks is essential to promote global collaboration and the adoption of optimized strategies (Stern, 2019). Hence, it is against this backdrop that this study aims to examine the optimized strategies for natural gas utilization.
