Parallel Carbon and Repsol Foundation Partner to Advance Scalable e-Fuel Feedstocks

Parallel Carbon is collaborating with the Repsol Foundation to advance their shared mission to unlock scalable, affordable e-Fuel production. The collaboration provides funding and structured support to test Parallel Carbon’s integrated DAC+H2 pilot system through the Repsol Foundation’s 14th Entrepreneurs Fund.  The pilot will validate real-world performance, accelerate technology development, and prepare Parallel Carbon’s solution for future industrial deployment.

The Repsol Foundation Entrepreneurs Fund supports innovative startups developing technologies with strong potential to decarbonise energy and industrial systems. The acceleration program provides access to pilot testing, expert mentoring, advisory services, funding, and increased visibility and networking opportunities. Parallel Carbon was selected based on the quality and scalability of its technology, the viability of its business model, its potential social impact, and the team’s ability to execute and scale.

The partnership reflects growing global demand for renewable and synthetic fuels, particularly for sectors that are difficult to electrify such as aviation, maritime shipping, and fertiliser production. Although e-Fuels can be nearly carbon-neutral over their lifecycle, the costs and insecure supply chains of today’s low-carbon CO2 and hydrogen feedstocks are significant barriers to project feasibility. Parallel Carbon’s approach addresses these challenges by producing both molecules together through an integrated system, enabling more secure and cost-effective feedstocks for downstream fuel synthesis.

As part of the collaboration, Parallel Carbon will use the support of the Repsol Foundation to mature its technology through pilot-scale operation, gather operational and performance data under realistic conditions, and validate product quality against the requirements of future e-Fuel applications. The company is working toward establishing a longer-term strategic partnership with an integrated oil and gas company, with the ambition to deploy a field pilot followed by a commercial demonstration at an industrial site, supporting integration into real operating environments.

Aranzazu Carmona Orbezo, Chief Technology Officer at Parallel Carbon, commented:

This collaboration marks an important step in moving our technology from controlled development into real operating conditions. With the support of the Repsol Foundation, we can demonstrate that integrated CO2 and hydrogen production can operate reliably, at relevant scale, and with a cost structure that helps unlock viable e-Fuel projects. Working alongside a partner with deep industrial experience strengthens our path toward deployment and impact.

Homayoun Bagheri from the Repsol Foundation added:

Through the Entrepreneurs Fund, we support startups with technologies that can meaningfully contribute to the energy transition and scale into real industrial solutions. Parallel Carbon’s proposal stands out for its technological innovation, its potential to improve the economics of synthetic fuels, and the strength of its team. This collaboration reflects our commitment to accelerating solutions that can be validated through pilots today and integrated into tomorrow’s low-carbon energy systems.

Aligned with the objectives of the Repsol Foundation Entrepreneurs Fund, this collaboration supports the advancement of innovative technologies with the potential to reduce emissions, strengthen industrial decarbonisation pathways, and enable scalable production of renewable fuels. For Parallel Carbon, the partnership represents a key milestone in validating its value proposition and progressing toward commercial deployment.
