Natural gas and liquefied natural gas (LNG) are often touted as pivotal elements in the transition towards a more sustainable energy system. As the world grapples with the need to reduce greenhouse gas emissions and combat climate change, the role of these resources in the energy mix has become a subject of intense debate.
The Role of Natural Gas
Natural gas is considered a cleaner-burning fossil fuel, producing fewer emissions of carbon dioxide (CO2) and harmful air pollutants when combusted compared to coal or oil. This has positioned natural gas as a potential bridge fuel in the transition away from more polluting energy sources. In regions where coal is a major part of the energy mix, switching to natural gas can provide immediate reductions in emissions of CO2 and air pollutants.
The role of natural gas as a sustainable option is not without its challenges though. Methane, the primary component of natural gas, is a potent greenhouse gas. Methane leaks, flaring, and venting along the supply chain can significantly undermine the environmental benefits of natural gas. Addressing these methane emissions is crucial for natural gas to be part of a sustainable energy transition. Fortunately, reducing or eliminating these emissions is feasible with current technology.
LNG’s Expanding Influence
LNG plays a key role in the global gas markets, enabling the transport of natural gas across oceans, which would otherwise be impossible through pipelines. This has allowed for a more diversified and secure supply of natural gas globally. LNG is recognized as a transition energy carrier that assists the worldwide transition from a fossil fuel-based energy system to a zero-carbon energy system.
Sustainable Transition and Challenges
The integration of natural gas and renewable energy resources in power generation ensures energy security and sustainability. It contributes toward a significant reduction of greenhouse gases (GHG), aligning with international agreements like the Paris Agreement. Still, the long-term role of natural gas and LNG in a decarbonized future remains uncertain. The gas industry has started to explore “greening” natural gas by using biomethane or blending hydrogen into natural gas networks. These pathways could offer decarbonization at scale, including in hard-to-abate sectors, while extending the use of existing natural gas grids.
The expansion of the natural gas industry as a transitional step towards sustainable energy is a contentious issue. Investing in natural gas infrastructure, such as pipelines and LNG facilities, may seem counterintuitive if these assets are destined to become obsolete in the pursuit of net-zero emissions. Critics argue that such investments waste resources and risk creating ‘stranded assets’—infrastructure that is underutilized or abandoned due to shifts in energy policy or market dynamics. Proponents contend that natural gas is essential for ensuring energy security and supporting intermittent renewable sources during the transition period. The challenge lies in balancing the immediate benefits of natural gas against the long-term goal of decarbonization, ensuring that today’s solutions do not become tomorrow’s burdens.
Employment Impacts
The transition from dirtier fuels to natural gas is a complex process with serious implications for jobs and employment. On one hand, the shift away from coal and oil can lead to job losses in traditional energy sectors, particularly in regions heavily reliant on these industries for employment. These areas may face economic challenges as they adjust to the changing energy landscape. On the other hand, the natural gas industry itself creates new opportunities, with jobs in extraction, pipeline construction, and plant operations.
Moreover, the transition to natural gas can act as a catalyst for broader economic development, spurring job creation in related sectors such as renewable energy technology and energy efficiency services. However, the ease of transitioning workers from traditional fossil fuel jobs to these new roles varies. While some skills are transferable, others may require extensive retraining and support. Policymakers and industry leaders must therefore prioritize workforce development programs to facilitate this transition, ensuring that workers are not left behind as the energy sector evolves.
Natural gas and LNG can play an important role in the energy transition, offering a cleaner alternative to coal and supporting the integration of renewable energy. However, their role as sustainable options depends on the effective management of methane emissions and the development of green gas technologies. As the energy landscape evolves, the gas industry must adapt to ensure that natural gas and LNG contribute positively to the goal of a sustainable, low-carbon future.
