In this report, we provide an overview of the current state of the hydroprocessed esters and fatty acids (HEFA) SAF industry, guided by the perspectives of interviewed industry stakeholders. Currently, the HEFA pathway is the only commercially deployed method to produce significant amounts of SAF and renewable diesel (RD).

2015年11月9日 · HEFA fuels are the most common drop-in biofuels; they can be used in diesel engines without the need for blending with petroleum diesel fuel. Currently, HEFA fuels are approved by ASTM International for use in jet engines at up to a …

2024年11月12日 · We're pleased to announce the launch of 11 new SAF prices - including spot market value assessments for SAF China, Malacca Straits, and US Gulf Coast. This adds to 13 existing General Index (GX) spot prices for Northwest Europe, as well as a broader set of HEFA production costs for the Netherlands and Singapore.

其中，加氢酯和脂肪酸煤油（HEFA-SPK）即通常所说的生物航煤主流技术，是目前唯一实现商业化的成熟路线；但因其以油料作物和餐厨废油为原料，原料供应规模受限，未来产能增长空间有限。

If all FOG is via the hydroprocessed esters and fatty acids (HEFA) pathway, 0.53 billion gallons of SAF can be produced annually, using literature estimates of FOG availability7 and FOG to HEFA yield.8 Algal biomass is attractive as a feedstock for biofuel production; it contains lipids that are suitable for SAF production through the HEFA or ...

In this report, we provide an overview of the current state of the hydroprocessed esters and fatty acids (HEFA) SAF industry, guided by the perspectives of the interviewed experts. Currently, the HEFA pathway is the only commercially deployed method to produce significant amounts of SAF.

HEFA-based SAF will lead the way in early development with more than 1.1 billion gallons of SAF being produced from HEFA feedstocks by 2030. ETJ will begin to become more prominent as ethanol plants that are located over geological formations that can support on-site sequestration of CO2 produce feedstock for ETJ-SAF plants.

2024年11月15日 · 可持续航空燃料（SAF）的重要性：为了使航空业在2050年达到净零碳排放，SAF的生产需要大幅增长，HEFA（加氢处理酯和脂肪酸）是SAF生产的主要方式，约占当前SAF产量的80%。

其中，加氢酯和脂肪酸煤油（HEFA-SPK）即通常所说的生物航煤主流技术，是目前唯一实现商业化的成熟路线；但因其以油料作物和餐厨废油为原料，原料供应规模受限，未来产能增长空间有限。

•In the context of the project, three case studies addressed the production of SAFs based on the pathway HEFA-SPK, considering exclusive use of soy, macaw or palm oil as feedstock. Now, the objective is to carry out a case study in which the input for the production of SAF is a combination of beef tallow and the vegetable oils previously mentioned.
