Momentum has been gathering in Asia Pacific and is set to pick up further in 2024, although activity will remain varied across the markets. In more developed markets such as Australia, South Korea, Japan and Singapore, policymakers are introducing a combination of blending mandates, targets and sponsorships for pilot projects, which has encouraged regional offtakers and fuel producers to consider opportunities for the development of green fuels in the region.
The new EU framework has binding targets for airlines and fuel suppliers – aviation fuel suppliers will have to blend increasing amounts of sustainable aviation fuel (SAF) with e-kerosene, starting with a 2% minimum blend in 2025 and rising to 70% in 2050. The UK Government has also said that it will implement a SAF specific "revenue certainty" model and has plans for at least five plants to be under construction by 2025 and for at least 10% of jet fuel to be made from SAF by 2030. The UK has a track record of delivering bankable revenue support models, which are targeted and have a tangible impact; for example, the renewables CfD, with similar models for hydrogen production now close to being rolled out. Although the APAC region is lagging slightly behind Europe and the US, driven by more fragmented regulatory regimes and the location of SAF production facilities, more facilities are being commissioned in Asia (notably in Singapore) to assist Asian airlines in adopting greener fuels. Japan is a front-runner in terms of regulatory requirements, with a target of 10% SAF use required for Japanese airlines and international flights at Japanese airports by 2030.
Infrastructure is in place
For e-fuels, such as e-methane, e-kerosene and e-methanol, produced from renewable electricity, CO2 and green hydrogen – in contrast to other clean hydrogen-based products – the necessary infrastructure already exists to bring them to the end user. For example, SAF can be substituted directly for fossil fuel-based products with no need for any change to the midstream or end user infrastructure, and uptake could be rapid.
Biofuel feedstock availability and supply
For biofuels (which are derived from plant material or animal waste), feedstock availability and supply constraints are a significant challenge for production facilities, particularly for those projects seeking third-party debt financing. Biofuels can significantly reduce CO2 emissions compared with fossil fuel-based equivalents, but the list of allowed feedstocks is restricted within the EU due to food security and sustainability concerns. The UK benefits from its existing waste-to-energy and biomass supply chains. The APAC region has a significant number of refiners and more abundant availability of potential feedstock; however, concerns around the robustness of sustainability standards mean that the import of feedstocks or fuels produced in Asia may lead to increased scrutiny.
There are non-edible alternatives – for example HEFA, particularly that made from used cooking oil, is a good potential feedstock – but there is a lack of infrastructure to collect and transport the used cooking oil at scale. Instead, some parties are looking at technologies to allow for the pre-processing of other feedstock to mitigate limited supply availability. There is also a lack of feedstock aggregators.
The anticipated increase in demand for green fuels could also lead to supply chain constraints for equipment and technologies similar to those seen in the hydrogen sector with electrolyser suppliers.
Flexibility is needed
The growth in this sector will provide opportunities for investors and flexibility will be needed to take account of the different production methods: (non-SAF) biofuel projects are generally smaller, so M&A and finance transactions in this sector are more likely to be structured on a portfolio basis (sometimes also including district heating or heat-to-power assets connected to the biofuel plants); whereas SAF plants and e-fuel production are typically larger, so the capex costs could be material enough to warrant project financing on a stand-alone basis. Aside from regulatory requirements, sustainability-linked financing structures are driving the adoption of greener fuels in the maritime and aviation industries.
For all of these projects, regardless of technology, ensuring that the plant has access to renewable power to satisfy RFNBO requirements (where applicable) and/or the fuel has the required carbon intensity (with appropriate quality certification) will be key. Looking ahead, the inclusion of products derived from hydrogen in the EU's Carbon Border Adjustment Mechanism (CBAM) could have an impact on imported fuel products, but there is currently some uncertainty about how to factor in the costs of embedded emissions for such products, which could impact investment decisions.
