project goal
Project Goal
  • Develop sugar beet to biofuel industry across North Dakota with five irrigated production regions.
  • First biofuel non-food sugar beet processing plant to be built in 2012.
  • Provide local economic opportunity
slide4

Introduction

  • Energy Independence and Security Act (EISA) of 2007 defines three classes of biofuels:
    • Conventional biofuel – 20% GHG reduction
    • Advanced biofuel – 50% GHG reduction

(Highlands EnviroFuels LLC conducted LCA of GHG emissions)

    • Cellulosic – 60% GHG reduction
slide5

Introduction

  • Sugar beets and sugarcane are uniquely qualified as advanced biofuels under EISA.
  • By 2022, about 15 billion gallons per year of advanced biofuels will be required
slide6

Introduction

  • North Dakota has great potential to expand irrigated sugar beet production, minimizing land competition with existing sugar beet food crops.
  • Because of their high sugar content, sugar beets can yield higher ethanol production per acre.
  • Growing sugar beet feedstock can reduce nitrogen requirements, water use and reduces CO₂ emissions
slide7

Literature

  • USDA (2006)
    • Examined the feasibility of ethanol production from sugar in the U.S.
  • Outlaw et al. (2007)
    • Analyzed the feasibility of integrating ethanol production into existing sugar mill that uses sugarcane juice
  • Yoder et al. (2009)
    • Investigated the potential development of an ethanol industry in Washington State using sugar beets
technology overview
Technology Overview
  • The plant makes most of it’s own energy.
  • Stillage waste from fermentation process is spray-dried and burned to produce thermal and electrical energy supplying about 75% of the plant’s energy needs.
  • Patent has been successfully lab tested by HRE and now needs commercial scale test .

methodology
Methodology
  • Divided into four sections:
    • Production assumptions
    • Balance sheet
    • Income statement
    • Cash flow financial statement
summary and conclusions
Summary and Conclusions
  • One of the most important factors that affect the profitability of the investment is the price of ethanol.
  • Changes in prices of co-products have a relatively minor affect on the profitability of investment
  • The ethanol plant can tolerate the feedstock price increase to a certain level without having a critical impact on profits.
additional research and study needs
Additional Research and Study Needs
  • Commercial scale burn test of fermentation sediment material to be used for plant energy
  • Optimal design of feedstock supply chain
  • Environment lifecycle of the biofuel produced
  • Impacts on rural employment
