With the increased demand for cleaner sources of energy, liquefied natural gas is fast replacing gasoline and diesel throughout the transportation industry and beyond. The ability to harvest a low-cost and low-emission fuel will play a significant role in meeting the current world’s energy needs and requirements. Currently, most countries are working to minimise harmful emissions while increasing access to environmental-friendly and affordable power.
They understand that shipping is the primary source of nitrogen oxide, carbon dioxide and sulphur emissions. Replacing the current shipping fuel with LNG makes it possible to reduce the environmental effects of shipping. Liquefied natural gas offers many advantages, especially for vessels in the light of the ever-tightening emission regulations. The conventional oil-based shipping fuels will remain the main option for most machines in the future, and the commercial opportunities of the LNG will be interesting for many projects.
While the operators of the vessels can use different technologies to comply with the air emission limits, liquefied natural gas technology is the only smart way to meet both the existing and upcoming needs for the primary types of emissions. LNG can prove to be competitive when it comes to pricing. Unlike other many solutions, LNG cases don’t require the installations of additional processing technologies. Here are the advantages of Liquefied Natural Gas as a shipping fuel.
Reduces Shipping Emissions
The international shipping sector currently accounts for approximately 7% of emissions of the global nitrogen oxide, 4% of annual emissions of sulphur and less than 3 per cent of the carbon emissions. Environmental innovations in the maritime industry will play an essential role in the efforts to manage and tackle global climate change.
Also, the shipping sector emits other elements which have been proven harmful to both animals and humans. Liquefied natural gas is the potential solution to all the shipping challenges, and there’s already a viable option for smaller machines. In most countries across the world, some vessels are currently running on LNG with more to be manufactured.
Liquefied natural gas provides the ability to minimise nitrogen oxide and sulphur emissions significantly. Potentially, all carbon emissions could be reduced by 20%. Currently, the sulphur content in shipping fuel must be at most 1% and using liquefied natural gas can help achieve this.
Lower Operating and Shipment Costs
Of all the benefits of LNG, its operational and shipment costs seem to be the most affordable and favourable component in the entire liquefied natural gas supply chain. Without this, the supply of the LNG would completely lack competitiveness. The fuel is unlikely to cause any bigger shipping costs even if more vessels are required to meet greater demands unless some security rules or stricter safety rules for handling liquefied carriers are introduced.
Currently, the only challenge to liquefied natural gas is the fact that there is little skilled crew available in the industry. With this in mind, if liquefied natural gas becomes a more important source of energy for ships, more maintenance as well as crew will be needed resulting in employment opportunities to many workers in the world.
It Is Clean
Liquefied natural gas is non-toxic, odourless and non-corrosive. When you expose it to the surrounding, it evaporates rapidly leaving no residue on soil or water. If spilt, liquefied natural gas would not lead to a slick since 100% of it evaporates leaving nothing behind. LNG mainly features methane and the primary products of combustion of the natural gas are water vapour and carbon dioxide.
Both oil and coal are made up of more complex molecules with a much higher carbon ratio and higher sulphur as well as nitrogen contents. It means that when you burn them, they release higher levels of dangerous emissions, which include higher ratios of carbon emissions, sulphur dioxide and nitrogen oxides. Fuel oil and coal also release other particles, such as ash into the surrounding, substances that don’t burn completely but instead they are carried into the environment leading to pollution.
The combustion of liquefied natural gas only releases small amounts of nitrogen oxides, sulphur dioxide as well as lower levels of carbon monoxide, carbon dioxide and other reactive hydrocarbons. Liquefied natural gas is the cleanest of all the fuels, and it can be used in various ways to reduce the emissions of harmful elements into the environment. Using LNG in the place of other shipping fuels emits fewer pollutants, and an increased reliance on the natural gas can significantly reduce the emissions of most of the harmful pollutants.
All gas carriers across the universe have been using LNG as part of the fuel source for many years. The safety record of the liquefied natural gas carriers is excellent. Even though many of the principles remain the same, utilising LNG as a shipping fuel introduces new systems with their associated risks.
To design, build and manage a gas-fuelled machine in a sustainable and safe way, all the risks will be investigated and reduced. These risks include explosion hazard, inexperienced crew, non-hazardous vs. hazardous and extremely low temperature of the LNG fuel among others.
