Mesquite: An Invasive Plant with Potential as Renewable Fuel
1.
2. (Prosopis L.) (Prosopis – laevigata) (Prosopis – pubescens)(Prosopis – glandulosa)
Mesquite:
Is a Non-Native,
Invasive Plant
Is a high consumer
of water
High BTU content as
an efficient fuel source
There are Federal/
State Eradication
Programs in Place
3. Sow: Phase I: Accumulated wood as on 6/26/09:
Total Counties: 25
Total Acreage: 560,642
Total Tonnage: 11,212,840
Total Acreage in 15 Counties: 9,000,000
Total Acreage of Mesquite in Texas 53,000,0000
4. Sow: Phase II: In-Process acreage as on 6/26/09:
Total Counties: 46
Total Acreage: 736,726
Total Tonnage: 14,734,520
5. Sow: Phase III: Harvestable Biomass
Item 1: Replanting Program
• After harvesting Mesquite the ranchers have the options below:
- Plant a sustainable crop to grow on marginal crop land
- 100 acre R&D test plot in Hamlin to show and test crops
Harvestable Plant Comment Land usage
Fast growing, bio mass eligible,
Switch Grass Ranch Land or Crop Land
suitable to west Texas
Seven years to mature, high yield Recreation Land or Tree
Poplar
for bio fuel, serves as wind break Farming Land
4 to 5 years maturity, Harvestable
Jatropha annually, high oil content, suitable Crop Land or Tree Farming
for poor soil
Fast Growing, Suitable for West
Hybrid Tree Tree Farming or Ranch Land
Texas, Harvestable 6 to 8 years
7. Biomass Conversion:
Tons MWs
Phase I Contracted Tonnage: 11,212,840 70
Phase II In-Process Tonnage: 14,734,520 85
Total: 25,947,360 155
Note:
• Represents a 20 year fuel supply
• No regeneration or replanting program assumed
• No substitute fuel sources or use of other agricultural or urban
waste assumed
10. Why Generate from Timber?
• Dependability
• Measurable Reserves
• Renewable
• Low or no measurable sulfur
• Low percentage of ASH – Less Than 2%
11. Why Generate from Timber?
Proven Technology
• Over 120 successful installations by selected manufacturer
• Other suppliers with similar proven technology
• Installations include electricity generating facilities,
industrial users, schools and hospitals
