Alternative Fuels

IMO 2030 and 2050 Plans - The IMO's initial strategy, adopted in 2018, aims to reduce greenhouse gas (GHG) emissions from international shipping. The strategy sets a target to reduce the industry's total GHG emissions by at least 40% by 2030 and 50% or more by 2050 compared to 2008 levels. The marine industry is actively exploring and transitioning towards alternative fuel options to address environmental concerns and comply with stricter emissions regulations.
LNG is gaining momentum as a cleaner-burning fuel option for ships. It produces lower emissions of sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter compared to traditional marine fuels. LNG-powered vessels are already in operation, and the infrastructure for LNG bunkering is expanding in various ports. LNG is a cryogenically cooled form of natural gas that is used as a fuel in ships.
Biofuels derived from renewable sources, such as vegetable oils, animal fats, or algae, are being explored as a viable option for the marine industry. These fuels have the potential to reduce greenhouse gas emissions and promote sustainability. Biofuel derived from Biomass residues can be a practical alternative to VLSFO 1. First Generation - Fatty acid methyl ester (FAME) 2. Second Generation - Hydrotreated vegetable oil (HVO) (everything that is not FAME)
Ammonia is being considered as a potential carbon-free fuel for the marine industry. It has a high energy density and does not emit carbon dioxide (CO2) when burned. However, challenges remain in terms of handling, storage, and safety considerations associated with ammonia as a fuel.
Hydrogen is another zero-emission fuel option that is being explored for marine applications. Hydrogen can be used directly in fuel cells to produce electricity for propulsion or as a combustible fuel. However, there are challenges related to hydrogen production, storage, and infrastructure development that need to be addressed.
Methanol is light, volatile, colourless, flammable liquid with a distinctive odour very similar to that of ethanol that can be produced from various feedstocks, including natural gas, coal, or biomass. Methanol can be used as a marine fuel, either in dedicated methanol-powered engines or as a blend with conventional fuels. It has close to zero emissions holding great potential especially for smaller vessels.
LPG is a natural by-product of raw oil which is safe and more environmentally friendly than traditional fuels. LPG is a clean-burning, high-energy-density fuel that offers environmental benefits for the marine industry, including reduced sulfur dioxide, nitrogen oxide, and particulate emissions. It is widely available in some regions, and its use in dual-fuel engines provides flexibility for vessels
