Key Points


RDL


Current Energy Situation• Primary Energy Supply, 768 PJ

• Domestic Energy Consumption, 508 PJ

• Electricity Supplied, 41,500 GWh (5,800 MW)

• Installed Capacity, 6,300 MW

• Petroleum, 200 PJ

• Natural Gas, 150 PJ (- 22% this year!)

• Electricity, 60 PJ,

• Petrochemicals, 47 PJ

• Industrial, Commercial, Residential, 43 PJ,

• Coal, 5 million tonnes/year, 110 PJ,

• Geothermal, 520 MW

• Wind, 350 MW

RDL


Electricity Generation in New Zealand

Hydroelectricity 60%

Geothermal 9%

Wind 6%

Natural Gas 13%

Coal 12%

Other v. small

Currently about 75% from New and Renewables

But, This Distribution is Changing Rapidly

RDL


Maui Gas Field is near Depletion

Replacement Options (200 PJ)

Petroleum Products,

Natural Gas,

LNG,

Coal/Lignite,

Hydro,

Geothermal,

Wind,

Biofuels - Ethanol from Agricultural Biomass,

- Methanol and Ethanol from Forest Biomass,

- Fats and Oils,

- Biogas,

Hydrogen/Fuel Cells,

Combination of the Above.

All have associated Shortcomings

RDL


The Way Ahead

Options

• LNG, Lignite and Wind are real options,

• Gas exploration encouragement,

Impediments

• Major Nimby & Banana constraints,

• Lack of coordinated planning,

• “The market will Decide”,

• Government will Regulate.

NRET likely to Increase

RDL


The Future Role of NRET

Commercially Proven in New Zealand

• Hydro

• Geothermal

• Wind

• Fastest Growing,

• 2 new wind farms under approval (435 MW).

• Biogas

• Small scale,

• Sewage and Landfill based.

All future development by the Private Sector

RDL



Near Commercially Proven in New Zealand

• Lignite

• via Gasification,

• Very Large (200-300 years supply)

• Biodiesel

• Technically Proven and Field Trialed,

• Rapeseed Oil and Animal Tallow Esters.

All future development by the Private Sector

RDL



Technically, but not yet Commercially, Proven

• Agricultural Biomass

• Sugar Beet and Maize,

- Ethanol/Gasoline Blends (E 2-5 and E 20),

- Ethanol (E 90).

• Forest Biomass

• Fermentation of Wood (Pinus Radiata, Eucalyptus),

- Ethanol/Gasoline Blends (E 2-5 and E 20),

- Ethanol (E 90),

- Biogas.

• Wood Gasification (Pinus Radiata, Eucalyptus),

- Methanol/Gasoline Blends (M 2-3, M 15),

- Methanol (M 85),

RDL



Research and Development Stage

• Hydrogen

• Coal,

• Biomass

• Water

• Fuel Cells

• Mainly System Integration

Limited Government and Private Sector Research

RDL



Work on Hydrogen and Fuel Cells

• Hydrogen

• Research Projects 7

• Demonstration Projects 3

• Fuel Cells

• Research Projects 3

• Demonstration Projects 1

Number of Small R & D Projects

RDL



Research on Hydrogen and Fuel Cells in New Zealand

• Hydrogen Production from New Zealand Coals,

• Fuel Cell System Integration,

• Grid Intergrative CHP Fuel Cell (1 kW),

• Wind based RAPS Alkaline Fuel Cell (2 kW),

Both Government and Private Sector Research

RDL



Demonstrations of Hydrogen and Fuel Cells

• Hydrogen RAPS, Rural Community (2 kW),

• Methanol Fuel Cell, Captive Power (2 kW),

• Associated Carbon Dioxide Sequestration,

• Water Electrolysis from Renewable Energy,

• Photo Electrochemical Hydrogen Production,

• Hydrogen Storage in Light Metal Hydrides,

• Hydrogen Storage in “sponge” materials,

• Thermo Chemical Hydrogen Production.

Both Government and Private Sector Demonstrations

RDL


The Role of Government

• Promote Investment in New Technology

• Establish Regulations, Standards & Codes,

• Establish the Institutional Infrastructure,

• Create an Environment for Private Investment,

• Establish long term Tax & Excise Duty Advantages,

• Promote Public Awareness,

• Engage with Industry in Promotion and Marketing,

• Maintain a Long Term Commitment.

Government does not take a Leading Role

RDL


Key Points

• Already a high level of Renewable Energy,

• Wind Energy is growing Rapidly,

• Lignite Gasification potential very large,

• Biomass options Technically proven,

• Limited additional NRET options,

• Private Sector has Choice of future Energy,

• Government Role largely Regulatory,

• Limited Current R & D in NRET .

RDL


A Final Word

Fischer Tropsch GTL/CTL Technology is Coming of Age!

• Economic at Current Oil Prices,

• Premium Quality Products,

• Brings Stranded Gas to Market

- 2,500 tcf Worldwide, 370 tcf in

APEC

• Well suited to Coal/Lignite Feedstock

• Utilizes Existing Fuel Supply Infrastructure,

• Environmentally Friendly,

• Minimal (zero) Social Disruption

Gasoline and Diesel may well live on for a while!
