Evaluating Biofuel Blend as Pilot Fuel for LPG Propulsion

In a recent trial led by the Global Clean Maritime Demonstration (GCMD) program, Eastern Pacific Shipping (EPS) partnered to assess the use of a biofuel blend as a pilot fuel for liquefied petroleum gas (LPG) propulsion. The trial involved the Kaupang, a mid-sized gas carrier equipped with an LPG dual-fuel engine. The pilot fuel, typically used in LPG propulsion, was replaced with a B30 biofuel blend of hydrotreated vegetable oil (HVO) and marine gas oil (MGO) provided by GoodFuels. This blend was bunkered in the Port of Vlissingen (Flushing). The use of LPG with a biofuel blend has the potential to reduce emissions compared to conventional fuel oil. To ensure the origination and quantity of the biofuel blend, GCMD collaborated with GoodFuels, Control Union, and IDS to deploy an element-based tracer in the HVO. Carbon dating was conducted independently to determine the biogenic carbon content in the blend. Verification of the biofuel blend’s quality was performed through extensive laboratory tests. The trial was witnessed by VPS throughout all stages, from biofuel transfer and onboard blending to bunkering aboard the Kaupang. The data collected from this trial, along with previous supply chain trials, will contribute to the development of GCMD’s assurance framework for green fuels. The results demonstrated a 20% net reduction in emissions compared to using very low sulfur fuel oil (VLSFO) when blending MGO with 30% biofuel as the pilot fuel for LPG combustion. The HVO used in the trial, produced from waste and residues, achieved an 83% reduction in emissions compared to using fossil MGO. This trial aligns with the Interim Guidance on the Use of Biofuels issued by the Maritime Environment Protection Committee (MEPC) 80. The goal is to achieve sustainable biofuels that meet a minimum requirement of 65% emissions reduction against conventional fuel to comply with IMO MARPOL Annex VI regulations. Dr. Sanjay Kuttan, Chief Technology Officer of GCMD, expressed confidence that the trial experiences will contribute to the development of a framework that assures emissions abatement when using green fuels. Utilizing biofuel blends with LPG may be a feasible pathway for ships to meet the decarbonization goals outlined by the IMO for 2030.

        This is an effective way to reduce greenhouse gas emissions in the transportation sector.However,the efficacy this approach will depend on the appropriate selection of biofuels blends,as well as on careful evaluation of their impacts on engine performance.
