Role of LNG in Energy Transition

In recent years, nations all over the world have been becoming increasingly aware of climate change that has resulted from the use of fossil fuels such as coal. Hence many are now shifting towards energy transition. The move from traditional fossil fuel-based energy systems to renewable energy sources is referred to as energy transition. Liquefied natural gas (LNG) has become a key transitional fuel that can play a significant role in the transition to a greener, cleaner future through net-zero emissions. LNG is natural gas that has been cooled to a temperature of -162°C, at which point it becomes a liquid. This process reduces the volume of the gas by a factor of 600, making it easier to transport and store. LNG is primarily composed of methane, with smaller amounts of other hydrocarbons such as ethane, propane, and butane. It is odorless, colorless, non-toxic, and non-corrosive.

Increasing demand for LNG

The global push towards cleaner and more efficient energy sources is a key driver for the increasing demand of LNG. As countries strive to reduce their carbon footprints and meet their emissions reduction targets under the Paris Agreement, LNG emerges as a more environmentally friendly transitional fuel. The Paris Agreement is an international treaty on climate change, adopted on December 12, 2015, at the 21st Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) held in Paris, France. The Paris Agreement aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels, with a goal of pursuing efforts to limit the increase to 1.5 degrees Celsius.

Compared to coal and oil, LNG emits significantly fewer greenhouse emissions. Many nations, notably Japan and South Korea, announced intentions to phase out coal-fired power facilities and expand their usage of LNG to decrease emissions during the COP26 climate summit in 2021.

Another factor driving the demand for LNG is its cost competitiveness. Recent technological advances, such as floating storage and regasification units (FSRUs), have made LNG more affordable and easier to transport. Additionally, the development of small-scale LNG facilities has made it possible to deliver LNG to remote areas, which were previously inaccessible. This has expanded the market for LNG and made it a more attractive option for countries looking to diversify their energy mix.

LNG can also play a role in enhancing energy security by providing a reliable source of energy to countries that lack domestic natural gas reserves. For example, Japan, which has no domestic natural gas resources, relies heavily on LNG imports to meet its energy needs. Moreover, LNG can be used to diversify a country’s energy mix, reducing dependence on a single source of energy and increasing resilience to supply disruptions.

Energy transition in the UAE  

The United Arab Emirates (UAE) is a significant player in the global LNG market, both as a producer and consumer of LNG. While the country has historically depended on oil and gas as its principal energy sources, there is now a rising emphasis on the role of LNG in the energy transition towards more sustainable energy sources. The country’s energy strategy is focused on diversifying its energy mix and reducing its reliance on oil and gas exports, and LNG plays a key role in achieving these goals.

The UAE is a major LNG producer, with most of its LNG exported to Asia. The country’s two LNG export facilities, the Abu Dhabi Gas Liquefaction Company (ADGAS) and the Ras Laffan Liquefied Natural Gas Company (RasGas), have a combined capacity of over 20 million tons per year. The ADGAS facility, located on Das Island, has been in operation since 1977 and is one of the oldest LNG plants in the world. The RasGas facility, located in Qatar, is a joint venture between Qatar Petroleum and ExxonMobil, and is one of the largest LNG facilities in the world.

The UAE is also exploring the use of carbon capture and storage (CCS) technologies in the production of LNG. The Abu Dhabi National Oil Company (ADNOC) has a significant role in the production and export of LNG in UAE. Currently, ADNOC is working on a new project called the Fujairah terminal, expected to be completed by 2026. It is a joint venture between ADNOC and several international companies such as Vitol and Total that aims to capitalize on the shift towards cleaner energy.

Many factors are boosting the UAE’s demand for LNG, including the country’s growing population, increasing industrial activity, and its attempts to minimize greenhouse gas emissions. The UAE has set ambitious goals for expanding the amount of renewable energy in its energy mix, with the objective of generating 50% of its power from clean sources by 2050. LNG is regarded as a critical transition fuel capable of reducing the country’s dependency on oil and gas while yet providing a stable supply of energy.

Drawbacks of LNG

Although there are numerous benefits to using LNG, it is important to consider its drawbacks as well.

1- Methane emissions: LNG is mostly composed of methane, a strong greenhouse gas with a significantly larger warming effect on the environment than carbon dioxide. The extraction, processing, and transportation of LNG can result in methane leaks, which contribute to climate change. To minimize methane emissions in the LNG supply chain, enhanced monitoring and control systems are being developed.

2- Infrastructure requirements: The specialized infrastructure required for LNG transport and storage, including facilities for liquefaction and regasification, as well as LNG tankers and storage tanks, can be costly to construct and maintain. LNG infrastructure requirements can potentially limit its utilization in some locations, especially in distant, more remote areas. 

3- Security concerns: Although LNG is not explosive or flammable in liquid form, it can be hazardous when it evaporates and becomes a gas. As a result, strict safety measures and regulations are required for the safe transportation and handling of LNG. The possibility of accidents and leakage in the LNG supply chain is a hazard that must be managed carefully.

Developments in LNG and support for renewables

The concept of “Green” LNG, an emerging trend fueled by decarbonization, is gaining popularity among companies in the LNG industry. It encourages LNG providers to offset their greenhouse gas emissions from the supply chain by investing in carbon-neutral initiatives outside of the industry. However, there is still considerable debate around the true sustainability of “Green” LNG.

Additionally, many companies are incorporating the sparsely deployed carbon capture and storage technologies, which can capture carbon emissions from the production and use of LNG and store it underground. This helps to reduce the emissions of LNG and make it a more attractive fuel option for countries and companies with climate targets. Governments around the world are also increasingly supporting renewable energy sources through policies and investments. For example, the European Union has set a target of achieving 32% renewable energy by 2030, and numerous countries have set comparable targets.

In conclusion, LNG has become a key transitional fuel that can play a significant role in the shift towards a greener and cleaner future through net-zero emissions. With increasing global demand for cleaner and more efficient energy sources, LNG emerges as a more environmentally friendly transitional fuel. The UAE is a significant player in the global LNG market, both as a producer and consumer, and is exploring the use of carbon capture and storage technologies in the production of LNG. However, it is important to consider the drawbacks of LNG, including methane emissions, infrastructure requirements, and security concerns. Despite these challenges, LNG remains a critical transition fuel capable of reducing the dependency on oil and gas while providing a stable supply of energy.
