Building on previous biomass supply analysis to provide robust feedstock supply information, the US Department of Energy has a project to update the Billion Ton Study and add a Best Use of Biomass Report. Billion Ton is End-use agnostic; the Best USe of Biomass is end-use explicit. Using economic and logistics simulation models and data […]
30-50% of the CO2 removals needed for a net zero U.S. economy could come via domestic terrestrial carbon sink enhancements. What’s needed? A project supported by DOE aims to specifyU.S. cropland carbon sink strategies and quantify potential impacts on global agriculture production,land use, and related greenhouse gas (GHG) emissions. Patrick Lamers of NREL presented these […]
In this presentation, we explored the state of the industry — including the renewable diesel, DME, SAF, hydrogen, renewable chemicals, materials, advanced biorefinery, efuels and carbon capture sectors. We looked at processes, feedstocks, products, finance, p[rices and risk. The Digest’s Jim Lane presented these slides at ABLC 2024.
A team of researchers is working to develop science-based design and operation principles informed by TEA/LCA that result in predictable, reliable, and scalable performance of preprocessing unit operations. The comminution and fractionation manuals that industry needs will contain design principles for various working envelopes of CMAs and critical process parameters (CPPs) for corn stover, forest […]
Industry needs to understand key sources of biomass variability (e.g., growth conditions, harvest conditions, storage degradation) to identify and quantify CMA distributions that propagate across unit operations to inform cost-effective management of variability. A team of researchers is working to identify and quantify the initial distribution of feedstock critical material attributes (CMAs) and inform strategies […]
A primary challenge in the design of a biorefinery is the storage, transport, and reactor feeding of the biomass feedstocks. Material handling/feeding is prone to process upsets such as jamming and clogging, resulting in increased downtime and ultimately higher costs. Commercial-scale conversion of biomass in biorefineries remains limited. A team of researchers aim to develop […]
In this presentation, we explored the new BDO Zone at Trois-Rivieres, Quebec— the feedstocks, the infrastructure, the workforce, how risks are mitigated. David Berthelot of Trois-Rivieres presented these slides on The BDO Zone, a program on Digest TV
In this presentation, we explored the new BDO Zone at Sarnia-Lambton, Ontario — the feedstocks, the infrastructure, the workforce, how risks are mitigated. Sarnia-Lambton’s Shauna Carr presented these slides on The BDO Zone, a program on Digest TV
A high production cost of renewable natural gas results from slow disintegration and hydrolysis of recalcitrant feedstocks in conventional AD leads to low productivity; low methane content of biogas produced from AD requires downstream purification; and waste rich in protein that results in high ammonia concentration that inhibits the process. A team of researchers led […]
Energy production from sewage sludge especially at small-scale using Anaerobic Digestion typically does not produce significant value with the current available AD technology due to low Carbon Conversion Efficiency (generally less than 50%). Here a team of researchers led by Birgitte Ahring of Washington State University proposed a novel concept, which will overcome this problem […]
