Marine biofuels have been identified as a readily deployable near‑term option for cutting emissions in shipping, but their expansion is being checked by limits on available feedstock, according to a The report dated 15 September 2026 that summarised comments made to Platts at APPEC 2026 in Singapore.
Industry participants described biofuels as the "lowest hanging fruit" in the suite of lower‑carbon marine fuels, a characterisation the report linked to their relative simplicity of use and compatibility with existing engine technology, which in turn supports near‑term operational uptake without wholesale engine replacement.
Feedstock availability constrains growth
The same witnesses reported at APPEC 2026 that tightening feedstock availability will increasingly restrict how fast biofuel use can expand as demand rises, a dynamic the reports item noted with reference to Platts' coverage of the conference in Singapore.
Contributors made clear that while blending and the use of biofuel blends are practicable now, scaling that use depends on the supply of suitable biological feedstock, and those supplies are not limitless as demand grows across shipping and other sectors.
Practical appeal and market limits
Participants told Platts that the practical appeal of biofuels stems from the ability to blend them into conventional marine fuels and to operate existing engines with those blends, an operational simplicity that contrasts with fuels requiring new engine designs or major retrofits.
At the same time, the report emphasised that this practical advantage will not alone guarantee rapid or sustained market growth unless feedstock availability is resolved, because constrained supplies will exert upward pressure on costs and limit the volumes that can be produced and delivered to ship operators.
Those at APPEC 2026 therefore framed marine biofuels as a near‑term, implementable step on the route to lower emissions, while also warning that they are not a singular long‑term solution unless supply chains and feedstock sources are significantly expanded, a point captured in the reports coverage of the Platts reporting from Singapore.
Operators, cargo interests and fuel suppliers were reported to be weighing the trade‑off between immediate deployability and future supply risk, with the conference exchanges cited by reports reflecting an industry balancing prompt decarbonisation measures against the practical limits of feedstock availability as demand scales.
In summary, the reports piece of 15 September 2026 relayed Platts' reporting from APPEC 2026 in Singapore that marine biofuels offer a near‑term route to emissions reductions because they can be blended and used in current engines, but that growth is likely to be constrained unless feedstock supply is increased to match rising demand.
