Scaling Up Ethanol Production for Emerging Biofuel Feedstocks

Posted by Matt in Alternative Fuels - May 13

With the investment in research and development of second and third-generation biofuel feedstocks, process engineering firms are seeing a rise in scale-up projects for ethanol production. However, some companies are now finding it difficult to move beyond R&D to pilot or commercial scale production for a variety of reasons. The most prohibiting factor many companies face when making the shift from pilot facility to commercial-scale production is the financing of these larger-scale ethanol processes.

Pursuing a pilot or commercial scale ethanol process requires a substantial capital investment in equipment and engineering, and many firms are unable to build these facilities due to a lack of financing. Even with government DOE grants and loan guarantees, companies find they hit a wall in building large-scale biofuels plants with the lack of available private or venture capital funding as compared to wind and solar projects. First-generation ethanol projects had the support of corn growers and companies with a vested interest in these first-generation feed stocks, while other biofuels companies are driven to seek debt financing or scrape together enough venture capital, both of which are currently hard to come by.

 
Many companies in this position are teaming up with organizations such as the NREL (National Renewable Energy Laboratory), which helps companies collectively solicit the DOE for ARRA (American Recovery and Reinvestment Act) grants. The NREL also helps companies test and prove the effectiveness and financial viability of their new technologies, as well as providing a conduit for companies to raise cash as they move from pilot facility to commercial production.
 
The conditions of these energy grants are often milestone-based. For example, Verenium Corporation (Nasdaq: VRNM) was recently awarded an additional $4.9 million from the DOE to support the development of their demonstration-scale cellulosic ethanol biorefinery facility. This grant is an extension of a 2008 grant following their successes in demonstration the viability of their technology. Mascoma Corporation, having already received well over $100 million in funding from both venture capital and the Michigan state development corporation, has recently raised $3.4 million of a $10 million convertible-debt financing round. While the conditions of this particular round were not disclosed, convertible debt financing is typically linked to an event or milestone which triggers the remainder of the investment to take effect.
 
As more of these companies are able to raise sufficient financing to pursue their large-scale processes, engineering firms which specialize in scaling up emerging technologies will see a rise in demand for both designing pilot facilities as well as large-scale commercial ethanol production.

The Technology & Process behind Cellulosic Ethanol Production: Part 2

Posted by Jennifer in Alternative Fuels - November 11

 Qteros, a start-up from UMass Amherst is on the forefront of the cellulosic ethanol industry. Their mission is to develop efficient and cost effective ways to make ethanol from waste products, and they have already broken ground on their demonstration scale facility. Qteros success comes, not only from their Q microbe (see Qteros website for detailed explanation as to how this process works), but also from their growth plan that allowed them to scale up production at progressively higher levels, while accurately predicting their costs.

 
The Technology Behind Cellulosic Ethanol:
Qteros’ primary focus when it comes to cellulosic ethanol production is on the Q Microbe, a super-bug microorganism that consumes plant and tree waste and converts these waste products into clean transportation fuel relatively simply. Traditional approaches to cellulosic biomass require intensive pretreatments using enzymes that break down the biomass into simple sugars. These enzymes and pretreatment are the largest cost contributor to cellulosic ethanol production. The Q Microbe, however, breaks down a wide variety of plant materials including corn residues, cane bagasse, woody biomass and cellulose waste, and produces ethanol from its own enzymes. This process reduces overall process time, saves money in pretreatment and eliminates the need to produce ethanol from essential food resources.
 
How SPEC Helped Qteros Scale Up Production:
  • Designed scale up from laboratory bench scale to pilot process
  • Created equipment ordering process parallel to laboratory development/design
  • Continuously revised floor plans to meet projected requirements for Qteros new program and facility
  • Helped vet potential buildings to evaluate what would be the best fit for their unique requirements

Will Cellulosic Ethanol Replace Gasoline? Part I: The Facts

Posted by Jennifer in Alternative Fuels - November 09

 Recent reports from Sandia National Laboratories and General Motors have estimated that by 2030, alternative energy and biofuels in the U.S will replace one-third of annual gasoline consumption. One of the clean technology forerunners contributing to this reduction is cellulosic ethanol. Cellulosic ethanol is already being produced on a commercial scale by several companies across the U.S. and is already commercially viable:

 
Benefits of Cellulosic Ethanol:
  • Fewer steps used to break down waste product means more conversion potential for fermentable components
  • No impact on essential food resources (unlike corn-based ethanol production)
  • Produced from agricultural waste products/non-food sources (switchgrass and wood chips)
  • Reduction in air pollution (traditional gas production can radiate roughly 75-80% more CO2 emissions)
  • Reduction in green house gases (traditional reformulated gas production can emit roughly 80% more green house gases)
  • Reduction in fine particle emissions (traditional gasoline production can discharge roughly 50% more fine particle emissions)

Part II: We\'ll outline an up and coming cellulosic ethanol producer, Qteros, and why their technology is making cellulosic ethanol an attractive fuel alternative.
