Okeelanta bagasse

Cellulosic Ethanol Biorefinery
Similar to a previously noted project in New York, the one in Florida will test the ability of biotechnology to overcome recalcitrance of cellulosic biomass and convert cellulose to sugars that then are fermented to make ethanol efficiently. Both sites will use wood scraps; they will differ in the other biomass used as feedstock.

Green Car Congress, who covers COB (Cruise On Booze) and BTL (Biomass To Liquids) topics extensively, recently had noted that a company in Japan has begun production of cellulosic ethanol from wood scraps. Florida Crystals is a sugar company. Like its many counterparts in Brazil, the Florida Crystals gets electric power from sugar cane fiber. Also, like the Japanese plant, it can use wood scraps.

The company claims it has reduced dependence on foreign oil by about 800,000 barrels a year thanks to its New Hope Power Partnership, located next to the company’s Okeelanta facility. The NHPP turns sugar cane fiber and urban wood waste into electricity used by the company and about 60,000 homes (how this directly eliminates oil imports is unclear, but I get that they’re making energy from biomass products, which is cool).

It would seem that the University of Florida thinks it cool as well. According to Autoblog Green, they selected the Okeelanta facility as the site for a new cellulosic ethanol plant. As previously noted cellulosic ethanol holds promises as a means of sustainable fuel.

The Common Purpose Institute website describes a unique public and industry research and commercial demonstration partnership, which includes University of Florida, U.S. Department of Energy, U.S. Department of Agriculture, Farmers, Power Providers, Biofuel Producers, and others. As part of a national, Biomass Biofuels Initiative, the focus is to study ways to grow, harvest, and use fast growing crops (called energy crop or closed loop biomass) and also biomass waste streams (e.g., clean yard waste, crop residues, etc.) as renewable energy biofuel or feedstocks for:

Researchers will use the $20 million demonstration project to test the idea of making cellulosic ethanol from sugarcane bagasse and other biomass sources. They project that the plant could produce between 1-2 million gallons of ethanol each year. One of the variables in production quantity is how easily the sugar cane fiber and wood can be broken down. There is ongoing development of pre-treatment methods and uses for the other byproducts.

    According to Leonardo Energy, the Worldwatch notes that long-term solutions in feedstock are ones like waste and ligno-cellulosic crops that avoid competition with food-production. Equally important as avoiding fuel-substitution, “a portfolio of options that includes dramatic improvements in vehicle fuel economy, investment in public transportation, and better urban planning” also is needed.

    Green Car Congress notes:

    The US Department of Energy (DOE) announced a Funding Opportunity Announcement (FOA) that will make available up to $33.8 million to support the development of commercially viable enzymes to enable bio-based production of renewable biofuels such as cellulosic ethanol.

    This FOA targets systems to hydrolyze and saccharify cellulosic biomass feedstocks, specifically enzyme, enzymes or enzyme systems capable of producing C5 and C6 monomeric sugars from pre-treated lignocellulosic biomass.

    Saccharification enables the biorefining process by breaking down pre-treated cellulosic material into more simple sugars, allowing them to be further processed through fermentation and ultimately turned into biofuels such as ethanol. Enzymes developed under this FOA must prove durable and effective in process-relevant conditions.

    Meeting the goal of producing ethanol from lignocellulosic biomass cost competitively by 2012, meeting the 20 in 10 goals of 35 billion gallons of alternative fuels production of which a significant fraction needs to be cellulosic based ethanol, and achieving the 60 billion gallon goal projected for 2030 will require significant technology improvements including improved enzymatic hydrolysis and saccharification in biological processes. To date a number of advances have been made that reduce the cost of these enzyme processes, but their use in process relevant conditions, at low cost remains to be achieved. Therefore, there is a need for a better “toolbox” of enzymes to meet the increasing demands of the future. —FOA

    While the entire process for lignocellulosic fuel involves the integration of feedstock handling and processing; pretreatment and hydrolysis; conversion technologies leading to production of alcohols and biofuels such as ethanol; and separation and purification of the biofuel product, this FOA is only focused on the enzymes involved in the hydrolysis and saccharification of pre-treated lignocellulosics under process relevant conditions.

    The ability of fermentative organisms to utilize the saccharification products from the enzyme hydrolysis will be evaluated independently by projects selected by DOE under another FOA.

    With a minimum 50% industry cost-share, this funding will total nearly $68 million to further enzyme commercialization efforts. This funding aims to further reduce costs of enzyme system preparations in process-relevant conditions. Since 2000, DOE enzyme development advancements have yielded thirty-fold cost reductions mainly on enzyme production.

    The awards have a ceiling of $15 million and a floor of $5 million.

    One thing I like about GCC posts; Millikin avoids talking down to the reader. If he wants to write “Saccharification”, so be it.
