- Singapore’s marine biodiesel trials are key for achieving net-zero by 2050, with significant hurdles in technology and infrastructure.
- B100 biofuel could improve emissions but lacks sufficient heating capacity for harbor crafts, and supply challenges remain.
- Limited EV harbor craft usage faces infrastructure and charging issues that may slow adoption without more supportive policies.
A new agreement between Pinnacle Marine and Singapore’s NTU Maritime Energy & Sustainable Development Centre of Excellence highlights Singapore’s commitment to achieving net-zero emissions. This collaboration aligns with the Maritime and Port Authority of Singapore’s (MPA) 2030 objectives, SP Global.
Growth of Marine Biodiesel Consumption
The International Energy Agency (IEA) projects that marine biodiesel use could reach 1.8 billion liters by 2030, accounting for 0.8% of international shipping.
With potential IMO emission pricing mechanisms in 2025, this share might increase to 1.4%.
MPA’s Ambitious Targets
The MPA aims for Singapore’s domestic harbor craft sector to achieve net-zero emissions by 2050.
As of March 2023, all new harbor crafts must either be fully electric, compatible with B100 biofuels or use net-zero fuels by 2030.
Research Focus on B100 Performance
The research collaboration will analyze the performance of harbor crafts using B100 biofuel, assessing engine efficiency and emissions data.
It will also develop handling, storage, and bunkering guidelines specific to B100.
Technical and Supply Challenges
B100 poses performance challenges for small harbor crafts that lack sufficient heating, a necessity for the fuel to function efficiently. This is unlike larger vessels, which are better equipped for such fuel.
High operating costs and potential supply shortages could limit B100 adoption without regulatory mandates. Market participants note the need for secure and widespread B100 supply should it become a standard requirement.
Charging Infrastructure Limitations
Insufficient charging facilities remain a substantial barrier to adopting electric harbor craft.
Most current charging stations are land-based, and local power grids may not support widespread electric harbor craft usage.
EV Harbor Craft Adoption Concerns
Range anxiety, repair costs, and battery degradation are prominent concerns within the harbor craft industry, impacting the feasibility of electric craft.
The community faces long charging times and a lack of suitable charging infrastructure, leading to hesitance in adoption.
