Japan increases its efforts to develop sustainable aviation fuels by focusing on cooking oil? ?

Maki Watanabe, a Japanese homemaker from Tokyo, carefully pours the oil used to deep-fry aubergines into a plastic container. She is doing her part in her Tokyo-based kitchen to help increase production of environmentally-friendly jet fuel.

"It'd take a lot to make an airplane fly, so I hope that we can collect more," said Watanabe. Her love of cooking allows her a donation of?about 40 litres per year.

Her contribution was pooled in a supermarket nearby, which is one of approximately 300 participants involved in a public/private project called "Fry to Fly", amidst the Iran War that has squeezed energy supplies and increased costs for this resource-poor nation.

Japan looks to consumers such as Watanabe more urgently than ever before, scrambling to achieve a goal to procure a tenth (10) of airline fuels from sustainable sources by the year 2030.

Used cooking oil is a cheap and sustainable feedstock that can be used to make aviation fuel.

SAF production in the United States is currently limited to 30,000 kilolitres, or just 0.3% of jet fuel consumption.

"We are facing a harsher reality than we expected," ANA and Japan Airlines said in a joint presentation about SAF efforts.

The rush to collect cooking oils highlights the challenges facing the aviation industry - one of the largest emitters of greenhouse gases - in trying to reduce its carbon foot print.

An investigation conducted last year revealed that only a small fraction of the SAF projects announced by airlines around the world have been implemented.

The high cost of SAF has been a barrier to adoption for years, but if we don't reach the volume target for 2030, refiners will face higher costs and airlines more.

This is because refiners might need to import more expensive SAF or feedstock in addition to possible penalties. This could have a knock-on impact?for airlines.

Singapore, a tiny aviation hub in Southeast Asia, relies heavily upon imported feedstock to reach its 1% goal.

The pivotal Year

This year is crucial for refiners to continue their SAF efforts.

The government has stated that final investment decisions must be made by March in order to ensure mass production in 2030.

Eneos, a leader in the industry, said that the amount of cooking oil collected will be a factor when deciding whether or not it will enter into a joint venture with Mitsubishi Corp for the production of 400,000 kilolitres SAF following the fiscal year 2028.

Committing to SAF production is a risky decision due to the complex and expensive production process. This includes everything from feedstock collection to hydrogenation and distillation.

JGC, the engineering firm that built Japan's first SAF commercial plant in 2010, said that a clearer demand outlook was required to justify increasing production.

The joint venture between REVO and Cosmo Energy, a biodiesel producer, has an annual capacity of around 30,000 kilolitres.

COLLECTION DRIVE STEPPED UP

As the target year nears, public-private supply chain initiatives are increasing their efforts.

Tokyo wants to encourage more companies to coordinate and raise awareness about oil collection in the city's 7,8 million households.

It distributed 13,000 plastic funnels with QR-coded instructions for collection in the last fiscal year after collecting a meager 160 kilolitres by 2024.

This figure was calculated using the formula from the JGC-Cosmo Joint Venture, Saffaire Sky Energy.

Yasushi Sato, a Tokyo official, said: "If we do not start now, we will simply not make it to 2030."

The retail giants Aeon and 7-Eleven have set up additional drop boxes.

UCO Japan, an organization of companies involved in the?recycling of such oil, claims that even if each drop of used oil was collected, it would still amount to 550,000?kilolitres. This would provide about a quarter the SAF needed in?2030.

Analysts say that since Japan collects nearly all waste oil available from businesses, SAF is virtually inevitable until technology like producing bioethanol-based Jet Fuel can be used commercially.

Motoomi Susi, senior economist, Norinchukin Research Institute said that the goal is ambitious, especially given Japan's current need for domestic feedstock. She added that used cooking oil will be the only option available in the near term. (Reporting and editing by Chang-Ran Kim, Clarence Fernandez and Jekaterina Glubkova)
