Presentation Transcript

  1. Biodiesel Potential in New Zealand • Andrew Smith • Advisor Renewable Energy • EECA • 26 July 2006

  2. Presentation outline • Why Biodiesel? • Production • Feedstock Availability • Costs of production • Government involvment • Biofuels Sales Obligation • Future directions • Summary

  3. Why Biodiesel? • Colonial fuel self sufficiency • Agricultural support • Renewability/Sustainability • Carbon emissions/Climate change • Security of supply

  4. The real benefits • Renewable • Low net carbon emissions • Numerous potential feedstock sources • Reduced exhaust emissions • Biodegradable and non toxic • Better for engines • Smells good

  5. The real issues • Cost? • Low temperature properties • Vehicle compatibility with higher blends • Unusual vehicle fleet in New Zealand • New Zealand is a long way behind many other countries

  6. Production • Oils or fats + methanol = biodiesel + glycerol

  7. Feedstock

  8. Feedstock

  9. Feedstock availability • Waste cooking oil – 4000 tonnes p/a • Tallow • NZ produces roughly 150,000 tonnes p/a • Of that 30,000 tonnes are used domestically • 120,000 tonnes are exported • If 120,000 tonnes can be used to produce biodiesel this would be equivalent to 5% of current diesel use

  10. Costs of production • Best estimates are a production cost of approximatley NZ$0.70 a litre • This makes biodiesel economic at oil prices of between US$45 – 50 bbl • As of yesterday crude oil was US$75 bbl • What will the price of oil be this time next year?

  11. Government Involvement • Since 2001 there has been an indicitive target of the use of 2 PJ (<1%) of biofuels in NZ by 2012 • To date been in a classic ‘chicken & egg’ situation • Fuel users can’t buy biodiesel so there is very limited demand • Biodiesel manufacturers won’t invest without good demand • Incentives aren’t really appropriate for something that is clearly economic currently • Solution is to stimulate demand

  12. Biofuels Sales Obligation • In 2008 the government is proposing to introduce a biofuels sales obligation • All oil companies will be required to sell a small percentage of their annual fuel turnover as biofuels • The percentage will ramp up till 2012 • Volume required will be tied to feedstock availability and ‘lumpiness’ of supply

  13. Future directions • Biodiesel from crops • Biodiesel or synthetic fuel from algal oil • Synthetic fuel from biomass

  14. Summary • Biodiesel a good option for supplementing mineral diesel supplies • Economic now when produced from waste and by-products • Close to being indroduced in New Zealand • Good potential for increased production in the future • Likely to be a subject of increasing R&D over the next 5-10 years
