Mazda's microalgae biodiesel R&D project wins NEDO backing, targets factory-fill diesel fuel by early 2030s
Mazda's microalgae biodiesel project has been selected for a NEDO program, with the company targeting factory-fill use in all diesel vehicles built in Japan by the early 2030s.
- More than 1 liter in approximately two weeks
- 1,000 liters
- Early 2030s
- FY2026
What Happened
Mazda Motor Corporation announced that its research and development project, "Development of High-Density Microalgal Biofuel," has been selected for the FY2026 NEDO program to develop and promote the commercialization of energy conservation technologies for a decarbonized society. The project targets real-world deployment of biodiesel fuel (HVO) refined from lipids extracted from microalgae. Mazda will conduct research and development covering the entire process from cultivation through lipid extraction. With the cooperation of Idemitsu Kosan Co., Ltd., Mazda will study producing biodiesel fuel using the extracted lipids as feedstock, and aims as one potential application to begin using biodiesel as factory-fill fuel for all Mazda diesel vehicles built at its plants in Japan in the early 2030s.
- Cultivation; recovery and drying; lipid extraction
- Fuel refining
- Fuel utilization, practical deployment and market rollout
More than 1 literin approximately two weeks
Produced from a 1,000-liter culture tank, according to Mazda's research findings to date.
Mazda has researched microalgae-derived fuels through joint research with academic institutions and cultivation trials at its plants.
Mazda's "Development of High-Density Microalgal Biofuel" project is selected for NEDO's program to commercialize energy conservation technologies for a decarbonized society.
Target for beginning to use biodiesel fuel as factory-fill fuel for all Mazda diesel vehicles built at its plants in Japan.
Mazda's stated horizon for realizing its vision, "The Joy of Driving Fuels a Sustainable Tomorrow."
Since the 2010s, Mazda has worked on microalgae-derived fuels, and it says biodiesel produced from lipids generated by microalgae is a promising liquid fuel for helping realize a carbon-neutral society. Mazda focuses on microalgae because they present minimal risk of competing with food crops or contributing to deforestation and can efficiently produce lipids in limited spaces. Through its research to date, the company says it has established technology for efficiently producing lipids from microalgae and confirmed the capability to produce more than one liter of fuel in approximately two weeks using a 1,000-liter culture tank. Building on those achievements, Mazda will continue advancing research and development toward practical application of microalgae-derived fuels.
“In response to the critical challenge of achieving carbon neutrality, Mazda is working with partner companies and government organizations that share the same vision to help build a regionally based circular energy society under its Multi-Solution Strategy. Through the widespread adoption of biodiesel fuel (HVO) derived from microalgae, we aim to contribute to greater domestic energy self-sufficiency, sustainable regional development, and enhanced industrial competitiveness. Looking ahead to 2035, we remain committed to realizing Mazda's vision: 'The Joy of Driving Fuels a Sustainable Tomorrow.'”
Why this matters
If it works, biodiesel made from microalgae could reduce the climate impact of new diesel vehicles while avoiding competition with food crops or deforestation, two risks Mazda says the feedstock avoids. The plan touches Mazda's plants in Japan and the refiner Idemitsu Kosan, which would study turning the extracted lipids into fuel.
