Fulcrum Bioenergy: Moves Ahead with Renewable Diesel

A couple of months ago Fulcrum BioEnergy announced the successful demonstration of its process to convert municipal solid waste (MSW) to jet fuel.  The company started out trying to convert MSW to ethanol.  However, the economics of ethanol, even quantities produced with feedstock as in expensive as waste, have been challenging on so many levels.  It makes sense to expand potential end products to include jet fuel and diesel that can be dropped directly into the transportation fuel infrastructure.

Velocys Thinking Big with Microreactors

Keep the applause down!  Contain your enthusiasm for yet another biomass- or gas-to-liquids company.  Over the past several weeks I have written about a number of privately-held developers of one technology or another intended to produce a drop-in renewable fuel from biomass or natural gas.  There are more,  In this post we check in on Velocys (VCL:  London), which stands out from the rest as a public company.  No matter that it's technology looks like that of the very next renewable fuel company, it is accessible to minority investors.

A Reason to Pay Attention to Sun Drop Fuels

It would be an oversight to leave Sun Drop Fuels out of my recent string of articles on advanced biofuels developers.  Based in Colorado, Sun Drop is trying to perfect a proprietary process to turn biomass of one sort or another into a drop-in fuel using ultra-high temperatures and intense pressure.  It is a gas reforming process that should sound very familiar after the last few posts on Renmatix, Primus Green Energy and Licella.  Carbon from the gasification of the biomass is mixed with a bit of hydrogen from natural gas is expected to yield a neat fuel ready to ‘drop in’ to existing gasoline infrastructure.

Renmatix Wants to be Your Sugar Daddy

In the post “Licella’s Pot is Boiling” on July 11, 2014, I described the progress Licella has made in developing its ‘supercritical water’ process to produce biochemicals and fuel from waste biomass.  Licella is not the only company that has been working on supercritical hydrolysis technologies.  Privately-held Renmatix based in Pennsylvania is also using high heat to break down cellulosic materials into sugar  -  the five-carbon sugar called xylose and six-carbon sugar called glucose to be exact.
