Yes, bacteria do it: The Digest’s 2017 Multi-Slide Guide to ethylene, protein from sun, thin air and seawater

Yes, bacteria do it: The Digest’s 2017 Multi-Slide Guide to ethylene, protein from sun, thin air and seawater

September 4, 2017 |

Hurricane Harvey has turned the world’s most widely-produced chemical, ethylene, into something of a rarer commodity because of refinery slowdowns. The US Department of Energy is supporting a project to produce transportation fuels via photosynthetically derived ethylene. The research team notes that “steam cracking of petroleum, is the largest CO2 emitting process in chemical industry”. […]

How much do algae biofuels cost? The Digest’s 2017 Multi-Slide Guide to algae biofuels’ techno-economics

How much do algae biofuels cost? The Digest’s 2017 Multi-Slide Guide to algae biofuels’ techno-economics

September 2, 2017 |

The US Department of Energy is supporting a project aimed at providing process design and economic analysis support for the algae platform to guide R&D priorities to commercialization. In short, a technolo-economic rationale for algae biofuels at scale, and co-=products along with those fuels or as a pioneer product set. The research team aims to translate […]

Gettin’ a new Cat: The Digest’s 2017 Multi-Slide Guide to Catalyst Costs

Gettin’ a new Cat: The Digest’s 2017 Multi-Slide Guide to Catalyst Costs

August 31, 2017 |

The US Department of Energy is supporting a project to develop a catalyst cost estimation tool that would enable rapid and informed cost-based decisions in research and commercialization of catalysts. As the research team notes, “Nearly all biomass conversion processes rely on catalysis as do many biochemical processes. Catalytic technology development is leveraged by a major portion […]

Gassy Gold: The Digest’s 2017 Multi-Slide Guide to a Biogas-to-Muconic Acid pathway

August 30, 2017 |

The US Department of Energy is supporting a NREL-led project to establish a novel gas fermentation bioprocess for secretion of an array of fuel and chemical intermediates. The project also aims to develop a novel methanotrophic biocatalyst and fermentation configuration for the production of muconic acid from renewable biogas. The research team ultimately demonstrated an […]

What’s algae worth? The Digest’s 2017 Multi-Slide Guide to algae biomass valorization

What’s algae worth? The Digest’s 2017 Multi-Slide Guide to algae biomass valorization

August 24, 2017 |

The US Department of Energy has established a project to reduce cost of algal biofuels by increasing intrinsic algal biomass value, with two specific goals. First, to Identify and isolate scalable, high-value key products in biomass and process streams to improve algal biofuels economics. Second, to quantitatively integrate biomass composition and carbon efficiency with cultivation parameters […]
