They say that if Comet Tsuchinshan-Atlas lives up to expectations as it nears Earth these days, it will be comet of the century. Beg to differ on the grounds that if Comstock Fuels technology lives up to expectations, that might well be a bigger event of planetary significance . Accordingly, let’s think of it just […]
Researchers have initiated a project to develop electrolyzers that can convert CO2 from biorefineries to produce useful products, and save the cost of air capture. Yet, research still has not been done on testing with CO2 from fermenter to understand how dilute/recycled CO2 will affect performance. Rich Masel of Dioxide Materials gave this presentation on […]
CO2 electrolysis can utilize waste CO2 from bioreactors to produce market competitive formic acid at commercial scales. Conventional design has energy and cost intensive downstream separations. A solid electrolyte design has tunable formic acid concentration with elimination of downstream separations. Dr. Feng Jiao of the University of Delaware gave this presentation on the project at […]
Today, lignin from pulp and paper is converted to polymer products through sulfonation. An industry goal, and the goal of this Ingevity / USC / Sandia project, is commercial products from lignin that provide 20% reduction in feedstock cost, because lignin coproducts must contribute $2-3/GGE to MFSP to meet DOE target of $3/GGE. Mike Kent […]
CO2 capture is increasingly viewed as an important technology towards meeting climate goals. Electrocatalytic systems excel at converting CO2 into C1 and C2 compounds, but are challenged in forming additional carbon bonds. Biological systems can build complex carbon compounds from simple carbon compounds, but are less efficient at upcycling CO2 due to gas diffusion limitations […]
By Cynthia Thyfault, CEO, QuantaVision Special to The Digest The US Securities and Exchange Commission recently finalized a climate disclosure rule that has sparked intense debate across political, corporate, and environmental spheres. Initially expected to align with the stringent climate regulations of the European Union, the SEC’s rule emerged significantly watered down after two years […]
CO2 Electrolysis + Gas Fermentation: a CO2 to Chemicals Platform, that’s the goal of this Argonne National Lab, LanzaTech and Dioxide Materials, project. It aims for room Temperature CO2 electrolysis (Anion Exchange Membrane based technology), and gas fermentation yield improvement through process development, metabolic engineering and arginine supplementation. Researchers have found that gas fermentation can […]
Isobutanol (IBA), feedstock for an ASTM approved pathway for SAF production, can only be produced at low levels in fermentation (<2%) due to toxicity. Plus, there’s energy intensive recovery to consider – high heat input or high vacuum required to separate from aqueous broth. The goal of this project is to decrease energy use (by […]
Developing Carbon Negative Biorefinery with Gas-fermenting Bacteria is the focus of this project, focusing on Acetogens as model gas-fermenting anaerobes, with high energy efficiency and fast electron/carbon consumption making them potentially a new chassis for the production of biofuels and value-added chemicals. Wei Xiong of NREL led the team that created this presentation for DOE […]
LanzaTech is back in the news with a budding venture based in manufacturing single-cell protein — usually a side product — as the main product for a new set of biorefineries they have in the pipeline. Plus, an ultra-low carbon footprint compared to business as usual. It’s not strictly a protein shake, but protein is […]
