Biofuels Definition
• Biofuels are fuels derived from biomass – any matter derived from plants or
animals
• Biofuels with limited compatibility with current fossil-fuelled engines
Ethanol: fermentation from starch/cane sugar (1st generation) or lignocellulosic feedstocks
(cellulosic ethanol)
Biodiesel: diesel replacement produced by transesterification of fats/oils
• Drop-in biofuels: Liquid bio-hydrocarbons functionally equivalent to petroleum fuels (eg from
pyrolysis or gasification/FT) , fully compatible with existing petroleum infrastructure and used in a
range of applications (Road, Rail, Marine and Aviation)
Renewable diesel/jet: A diesel/jet replacement produced by hydrotreating fats/oils

Climate ChangeIPCC AR5 - 2014
Human influence on the climate system is clear,
and recent anthropogenic emissions of
greenhouse gases are the highest in history.
Recent climate changes have had widespread
impacts on human and natural systems.
COP 21 –Paris Agreement
Members promised to reduce their carbon output
"as soon as possible" and to do their best to
keep global warming "to well below 2 degrees C"
Climate Action Tracker
With 158 climate pledges now submitted to the
UN, accounting for 94% of global emissions, the
Climate Action Tracker confirmed this would
result in around 2.7°C of warming in 2100 – if all
governments met their pledge
![Page 12: Biofuels for New Zealand · 2020-03-22 · Biofuels Definition • Biofuels are fuels derived from biomass –any matter derived from plants or animals • Biofuels with limited compatibility](https://reader033.fdocuments.in/reader033/viewer/2022043022/5f3da4d0422cd955c21d0b5c/html5/thumbnails/12.jpg)
Impacts of Climate Change
• New Zealand climate is changing.
• Warming is projected to continue through the 21st century along with other changes in climate.
• Annual average rainfall is expected to decrease in the northeast South Island and northern and eastern North Island, and to increase in other parts of New Zealand.
• Drought frequency could double or triple in eastern and northern New Zealand by 2040, and fire weather is projected to increase in many parts of New Zealand.
• Regional sea level rise will very likely exceed the historical rate (1971–2010), consistent with global mean trends.

NZ GHG Emissions - Where’s the 30% reduction going to come from?

NZ Energy Consumption – Mitigation Options
![Page 15: Biofuels for New Zealand · 2020-03-22 · Biofuels Definition • Biofuels are fuels derived from biomass –any matter derived from plants or animals • Biofuels with limited compatibility](https://reader033.fdocuments.in/reader033/viewer/2022043022/5f3da4d0422cd955c21d0b5c/html5/thumbnails/15.jpg)
Royal Society Review - Mitigation Options April 2016
….there is one main highway to proceed towards net zero emissions;
1. Implement all feasible means of avoiding the burning of fossil fuels,
2. Compensate for unavoidable emissions through afforestation
3. In the longer, compensate with bioenergy coupled with CCS
This includes displacing the use of coal, oil and gas with renewable heat, renewable electricity and biofuels, and possibly green hydrogen. A strong focus on reducing demand and increasing efficiency is an imperative.

RFS2 - How does it work?
• Obligated parties can carry over unused RINs between compliance years. They may carry a compliance deficit
into the next year. This deficit must be made up the following year.
• Penalties over US$10,000,000 have been applied for non-compliance.
Refiners and imports are
obligated to delivery a certain
amount of biofuel

Further, advancements in production technology will make biofuels competitive at US$50-$70/bbl

Views on Biofuels in NZQualitative Assessment – 26 Stakeholder interviews
Biofuels cannot be automatically assumed to be a positive for social acceptance.
Diverse views follow whether liq. biofuels will substitute jet, diesel or marine industries.
No clear main enablers are standing out at the moment.
Economics is agreed to be the main hurdle followed by technology.
Government is seen as a follower - Industry needs to drive initiatives and prove their feasibility.
Stakeholders were quite keen to work systematically through a plausible scenario.

Conclusions
• Biofuels are currently playing a key role around the world in
addressing local strategic priorities of; Climate change
Energy Security
Rural economic development
• Shift from food derived biofuels towards waste or non-competing
crops
• Lignocellulosic biofuels are becoming commercial, but need; High crude prices
Higher carbon prices
Further technology development to lower costs
