Italian hydrogen company Tulum Energy raises €22.9 million to advance scalable low-carbon hydrogen production


Milan-based Tulum Energy, a startup producing clean hydrogen solutions for industrial applications, has raised €22.9 million in a Seed funding round to accelerate the development of Tulum’s innovative clean hydrogen production technology.

The round was co-led by TDK Ventures, a subsidiary of TDK Corporation, and CDP Venture Capital, with participation from Doral Energy-Tech Ventures, MITO Tech Ventures, and TechEnergy Ventures.

We are thrilled to partner with TDK Ventures, whose global reach and technical expertise will be invaluable as we move to pilot and commercial scale,” said CEO and Co-founder Massimiliano Pieri. “Their investment and belief in us are an equal win for both of our companies. Along with their financial investment comes its famous ‘TDK Goodness,’ which provides access to various strategic synergies across TDK’s power electronics and materials businesses. Similarly, Tulum has the very real potential of expanding TDK’s impact in decarbonisation, particularly in hard-to-abate sectors.

Founded in 2024, Tulum has been spun out of Techint Group, a global leader in steel, engineering, and energy. Built by TechEnergy Ventures, the corporate venture capital arm of the Techint Group’s Energy Transition Division, the company is dedicated to providing a scalable, efficient, and cost-effective alternative to conventional hydrogen production.

Tulum aims to commercialise a scalable approach to hydrogen production, utilizing proven electric arc furnace (EAF) technology, commonly used in steel production at capacities of over 100 megawatts, in a novel configuration for producing hydrogen.

With technical backing from Tenova, Techint’s subsidiary that produces EAFs, Tulum looks to deliver hydrogen at levelised costs comparable to conventional grey hydrogen, while achieving up to 95% reduction in greenhouse-gas emissions.

Tulum is led by CEO and Co-founder Massimiliano Pieri, formerly CEO of M2X Energy and an executive at Eni Next, along with CTO Donald Kendrick, previously CTO at methane-pyrolysis company Ekona.

The company leverages commercially available electric-arc plasma reactor technology to achieve cost parity with traditional hydrogen production methods, while also reportedly reducing carbon emissions.

Tulum expects to reach commercial operations directly following the first pilot and achieve hydrogen production costs matching or beating fossil fuel-based alternatives without relying on incentives or the sale of the potentially valuable carbon co-product.

Tulum’s innovative reactor could be a game-changer in geographies where green hydrogen is cost-prohibitive or logistically infeasible,” said Nicolas Sauvage, President of TDK Ventures. “Their technology offers superior energy efficiency, smaller land footprint, and compelling economics that meet the immediate needs of heavy industry. By harnessing the potential of turquoise hydrogen, Tulum is well positioned to decarbonise heavy industry and create a more sustainable future for generations to come.”

Tulum’s approach to hydrogen generation is designed to overcome the high costs and infrastructure challenges currently faced by alternative clean hydrogen solutions such as green-hydrogen.

Key advantages of its technology include:

  • High efficiency: A projected energy requirement approximately five times more efficient than the best green hydrogen methods
  • Scalability: By repurposing EAF technology that is already widely used at way above 100 MW capacity (i.e. the anticipated power capacity of a full size Tulum commercial plant reactor), Tulum can meet the massive scale of today’s existing users of hydrogen such as steel producers, chemical plants, and refineries (in the range of 20 to 200 tons/day and above)
  • Cost competitiveness: Anticipated levelised production costs on par with grey hydrogen and significantly more competitive than other sustainable hydrogen production pathways, even without subsidies or the sale of the valuable carbon co-product
  • Non-catalytic technology: The electric arc is a high-temperature heat source that allows the methane pyrolysis reaction to occur without the technical and operational hurdles that catalytic solutions entail
  • Reduced footprint: Tulum’s plants require eight times less land than green hydrogen facilities, enabling on-site production and reducing transportation costs

The proceeds from this oversubscribed Seed round will be deployed to construct Tulum Energy’s inaugural pilot plant in Pesquería, Mexico, located within the industrial complex of Ternium, Latin America’s leading steel company and a part of the Techint Group.
