At first glance, RD and SAF appear nearly inseparable—often co-produced in HEFA systems, governed by overlapping policy frameworks, and sharing many investors, incentives, and technologies. Traditional analysis sees them as market twins. Yet, in this analysis out from SAF adoption leader and hard-working champion IAG, the numbers for SAF lag far behind renewable diesel. Converting […]
This presentation from Sandia National Laboratories summarizes a workshop on biorefinery integration held in October 2025. The objectives were to develop a shared vision for the refinery of the future and identify R&D needs for processing both bio-based and fossil feedstocks. Recommendations from industry and research attendees included developing centralized lab facilities, analytical methods for […]
This presentation deck from ABLC highlights their position as a pioneering technology company focused on 2nd generation biofuels from agricultural residues. They emphasize that 2G biofuels offer a practical path to net-zero in hard-to-electrify sectors like aviation and, when combined with carbon capture and storage, can actively remove CO2. Iogen notes that despite early challenges, […]
As the search for sustainable aviation fuel (SAF) intensifies, alcohol-to-jet technology has emerged as a promising yet perplexing pathway. Promising because of the progress on technology and projects. Perplexing because traditional techno-economic analysis is capturing part of the story—costs, feedstock flows, policy incentives—but struggles to explain why some technologies persist and others stall, even with […]
This presentation from NexantECA focuses on decarbonizing marine shipping, noting its CO2 emissions and the need for alternative fuels to meet IMO GHG reduction targets. NexantECA projects a shift from conventional fuels like HSFO and VLSFO to lower carbon intensity options such as LNG, ammonia, hydrogen, and methanol by 2050. The guide also addresses the […]
By Sam A. Rushing, President Advanced Cryogenics, Ltd. Special to The Digest The long term sustainability of first generation ethanol facilities, through advanced biofuels plants, is realized by making money from all the by-products; and of course, CO2 is one of the leading components of this by-product list. There are many variables associated the feasibility […]
Global Bioenergies highlighted its unique, ASTM-certified biological process for SAF production from renewable resources. They focus on bio-SAF for the US and e-SAF for Europe. Their technology offers fewer steps than competitors. The niche cosmetics market serves as a stepping stone to scale up their SAF process.
Many Digest readers know quite a lot about the 15 percent ethanol blends (E15) which have been long proposed, and long opposed, for the United States. Even when higher ethanol blends are an everyday reality elsewhere around the world. You probably know the basics of E15’s appeal: It’s Sustainable. E15 reduces greenhouse gas emissions. It’s […]
DG Fuels presented its patented technology for high carbon conversion SAF production, boasting zero CI and low costs. Their Louisiana project is nearing FID in 2025, with presold capacity. DG Fuels aims for the lowest unit production cost globally, envisioning over 20 sites utilizing cellulosic biomass and hydrogen to produce significant SAF volumes.
CAAFI’s Steve Csonka discussed advancing Sustainable Aviation Fuel (SAF) development through a revised Public Private Partnership. He highlighted the U.S. need for diverse energy and the ongoing interest of agencies like the DOE and USDA in SAF commercialization. The focus is on making SAF affordable through industry commitments and a new PPP effort supporting research […]
