New study shows local production of sustainable aviation fuel could support fuel resilience and security in Aotearoa New Zealand

The feasibility study was funded by Air New Zealand and the New Zealand Government, and undertaken in partnership with Scion, Z Energy (Z), and WoodBeca.

LanzaJet, one of the world's leading SAF technology providers and sustainable fuel producers, has found that locally produced New Zealand SAF could meet up to a quarter of the aviation fuel needed for

The study found that using domestically grown woody waste for SAF has the potential to contribute hundreds of millions of dollars to New Zealand's economy per year and create hundreds of new regional jobs.  Significant investment in infrastructure will be needed to achieve this.

Air New Zealand Chief Sustainability and Corporate Affairs Officer, Kiri Hannifin, says the initial findings from the study are promising, however establishing and stimulating a new SAF market will be critical to ensure New Zealand doesn't miss out on securing homegrown raw materials like woody waste for its own use and benefit.

"These initial findings support that alternative jet fuel can be produced here in Aotearoa from our own locally-grown woody waste, which is very positive for a country that is heavily reliant on long-haul aviation and trade and currently imports 100 percent of its jet fuel," says Ms Hannifin. 

"Alternative jet fuel such as SAF is currently the only real tool available to address carbon emissions from long-haul aviation, so it's crucial for connecting New Zealanders, tourists, and exporters with the rest of the world."

"SAF is already being used in small quantities by many airlines globally today, but it currently represents only a fraction of overall aviation fuel and comes at a high premium so anything that can be done increase supply and to reduce that premium is vital. The right settings and regulatory environment will be important as New Zealand considers homegrown SAF because it's the only way to secure the necessary global investment.  There is already significant international momentum and in our view New Zealand shouldn't get left too far behind or we risk seeing the flow of capital go elsewhere or our valuable raw materials being swooped up by other markets for their own SAF."

SAF is almost chemically identical to fossil jet fuel and has the same emissions when burnt in an aircraft, however it has significantly lower emissions than fossil jet fuel over the full lifecycle of the fuel, from raw material production to combustion. For example, Air New Zealand's June delivery of 500,000 litres of SAF into Wellington had an 89 per cent life-cycle emissions saving versus the equivalent fossil jet fuel.

LanzaJet CEO, Jimmy Samartzis, says the company is pleased with the initial results from the feasibility study and reaffirms its commitment to the region.

"Building a new industry requires developing a broad ecosystem for SAF in New Zealand, anchored in technology and supported by policy, capital, and demand to help attract funding and make it at a price airlines can afford.  We are seeing many countries move quickly to put mechanisms in place to stimulate, produce and export their own SAF in the future, because aviation is critical to global economies, as it is here in New Zealand.

"CirculAir^TM, the SAF production approach assessed in the study combines the technologies of LanzaTech and LanzaJet to convert waste carbon into SAF. The process starts with LanzaTech's carbon recycling technology, which (in this case) converts gasified forestry residues into ethanol. LanzaJet then converts that into SAF using its proprietary and industry-leading alcohol-to-jet (ATJ) technology.

"The good news is that turning woody biomass into SAF is technically possible in New Zealand, and with the right settings, is an industry that can get started fairly quickly. We look forward to completing additional analysis into what other feedstocks, such as municipal household and commercial waste, could be used to make domestic SAF production an even more attractive option in Aotearoa," said Jimmy Samartzis, LanzaJet Chief Executive Officer.

A second phase of the study, exploring the potential for municipal solid waste (household and commercial waste) as a feedstock for the LanzaTech carbon recycling process, is expected to be completed over the next few months.
