Audi and Hyundai are merging brains, signing into a multi-year agreement to develop fuel cell technology.

The agreement comprises of a “patent cross-licensing agreement”, which allows Audi, Hyundai, affiliates, and its parent/sister companies Kia and Volkswagen to share patent licenses and access to “non-competitive” parts, combining research and development efforts to build fuel cell technology. This will include access by Audi to Hyundai’s ix35 Fuel Cell, NEXO, and supply chain expertise, which has grown rapidly.

“This agreement is another example of Hyundai’s strong commitment to creating a more sustainable future whilst enhancing consumers’ lives with hydrogen-powered vehicles, the fastest way to a truly zero-emission world,” said Euisun Chung, vice chairman at Hyundai.

“We are confident that the Hyundai Motor Group-Audi partnership will successfully demonstrate the vision and benefits of FCEVs to the global society.”

Other areas which Audi and Volkswagen hope to tap is Hyundai’s core component capability through Mobis, its component subsidiary which produces hydrogen fuel cell stacks in a South Korea factory. In turn, Audi has worked on fuel cell technologies for almost 20 years with its flagship A7 h-tron, indicating plans to launch an unnamed fuel cell SUV within the decade.
