In this presentation, researchers chart the progress of a project focused on developing a system for in situ biogas upgrading via biological conversion of CO2 to CH4. The goal is to convert CO2 in biogas to high-quality renewable natural gas (RNG) meeting pipeline specifications. Tasks include technical verification, biological CO2 conversion with membrane-assisted H2 delivery, […]
This presentation by Kevin Harrison from the National Renewable Energy Laboratory aims to scale down a hydrogen-biomethanation system into a mobile RD&D platform to enable faster research, IP development & validation, and improved gas mass transfer to reduce the cost of RNG via biomethanation. Operational data from commissioning a 700L system showed achievement of 98% […]
This presentation by Lutgarde Raskin from the University of Michigan describes a project developing an integrated biochemical and electrochemical technology (IBET) system to reduce the production cost of renewable biomethane by at least 25%. The three components of the system have been built and achieved most of their performance targets. Model and control strategy development […]
This presentation by Lance Schideman from the University of Illinois at Urbana-Champaign, focuses on a cloth filter anaerobic membrane bioreactor (CFAnMBR) for municipal wastewater treatment. The CFAnMBR technology achieves high flux with low cleaning energy, resolving major limitations of mainstream anaerobic digestion. The system results in net energy production, eliminating aeration needs but requires optimization […]
This presentation by Shulin Chen of Washington State University aims to reduce the production cost of pure biomethane derived from waste through an intensified anaerobic digestion (AD) system. The IVAD system integrates a hydrothermal reactor, a hyperthermophilic anaerobic acidification reactor, and a pressurized thermophilic anaerobic methanogenesis reactor to improve digestibility and methane purity. The project […]
This presentation from the ABLC Connect series on Digest TV assesses the current state of advanced biorefinery technologies and projects, highlighting both the positive aspects, such as high demand for carbon-negative energy, and the challenges, including expensive cleaning processes and slow feedstock owner adoption. The document points to huge growth potential for the industry, driven […]
This deck provides a brief overview of the shipping industry, highlighting its significant role in global trade and its substantial contribution to greenhouse gas emissions. The presentation deck emphasizes the need for sustainable marine fuels to reduce the industry’s environmental impact, outlining the challenges and potential solutions. It discusses the current generation of marine engines […]
This presentation by Steve Weiss, co-founder and CEO of Grey Heron, focuses on the critical importance of securing offtake agreements for building successful biofuel plants. Offtake agreements are legally binding contracts that guarantee the sale of a plant’s output, ensuring a steady revenue stream. The author emphasizes that offtake agreements are crucial for attracting financing, […]
This presentation deck outlines a plan for a new sugarcane ethanol and power plant in Imperial County, California. The project, known as Sugar Valley Energy, will produce 76 million gallons of ethanol annually with a low carbon intensity score of 11. This ethanol will be used to produce sustainable aviation fuel (SAF) and renewable diesel, […]
