  1. Energycane:First Year Brian Baldwin, Herbaceous Feedstocks Meeting San Antonio, Texas 22 February 2010

  2. Energycane • Hybrid of sugarcane and wild cane • Bred for high fiber, high biomass • Tolerance to cold weather • Fermentable sugars

  3. Concept • Energycane • Cellulose for bioethanol/biomass • High yields and perennial • Limitations of sugarcane’s abilities in the “North” • Sugarcane infrastructure in place • Advantage of sucrose • Can be fermented if harvestable • Sugary bagasse is subject to enhanced fermentation as a precursor to cellulose SSF • Capture-able with slow pyrolysis

  4. Common Energycane Germplasm *from USDA-ARS-SRU, Houma, LA

  5. Base Field Dimensions • Plot = 10 m x 3 rows (6m) • Sacrifice row (Brix) • Harvest 2 rows • Base Rep = 10m x 30m • Base Test = 132m x 30m • (or any combination) • inclusion of other genotypes

  6. Spring • Emergence data – date and rating (shoots/plot) • Date of 50% emergence and soil temp • Data during growing season • Height, bi-weekly • Brix monthly from sacrifice row

  7. July • Stalk counts and diameter

  8. Fall 2009 • Harvest Data EOS • Each location needs to fix that time • Stalk count and diameter • Final height • Rating after first hard frost (differences?) • Final Brix – want a 50 ml sap sample, freeze • Fresh harvest weight • Sap yield • Stalk moist weight • Stalk dry weight • Stalk samples for fiber analysis Starkville MS; Nov 2007

  9. Fall/Winter • Harvest (other two rows) • Moisture • Southern locations • Harvest and weigh

  18. DoE Feedstock Partnership Collaborators • Bill Anderson via Wayne Hanna (USDA via UGA, Tifton, GA) • Brian Baldwin (MSU, Starkville, MS) • Jürg Blumenthal (TAMU, College Station, TX) • Charlie Brummer (UGA, Athens, GA) – 2008 addition • Kenneth Gravois (LSU, St. Gabriel, LA) • Jimmy Ray Parish (MSU, Raymond MS) • Ed Richard /Tom Tew/Anna Hale (ARS-SRU, Houma, LA) • GoroUehara, (U Hawaii, Waimanalo) – 2009 addition • Ted Wilson, et al. (TAMU, Beaumont, TX)

  21. Issues/Major Factors

  22. Obstacles to Data Collection • El Niño • Rain, rain, rain, rain, rain, and still rain • Starkville ended 2009 @ 84.5” (54” normal) • Same at: Tifton, Athens, St. Gabriel • The weight of biomass • Energycane harvested at 60-70% moisture • A dry weight of 3 T/A is actually 4.2 T/A • Most sites harvest by hand

  28. Summary Findings • Brix affected by rain • Brix affected by genotype • Spring onset of growth different • Early onset in genotypes closer to sugarcane can lead to higher yields at the southern locations • Early onset of genotypes closer to wild cane are not good for maximum growth in the “North” (spring frost)

  29. Summary Findings, cont’d • Yield varies by genotype • Location matters, with Tifton, GA toping locations • Well-drained soils, with excellent rainfall • Ho 72-114 seems best adapted to all locations tested.

  31. Energycane Drawbacks • Energycane • Of tropical origin • Not photoperiodically senescing • Wet harvest • Removal of nutrients • Limitations of sugarcane’s abilities in the “North” • Advantage of sucrose • Limited accumulation, especially with excess rain • Sugar and fiber are inversely proportional • Associative nitrogen fixation
