Tulum Energy Selects Scandinavian Energy Company for Mexico Turquoise Hydrogen Pilot Plant

On the road to ramping up hydrogen production in Mexico, Tulum Energy just handed off the EPC contract for its first turquoise hydrogen pilot plant in Pesquería, Nuevo León to Scandinavian Energy Company. Slated to run through 2026–27, the project will cover detailed design, engineering, and construction management for a facility that uses methane pyrolysis to churn out clean hydrogen and solid carbon by-products.

This pilot is backed by a $27 million seed round led by CDP Venture Capital and TDK Ventures, with TechEnergy Ventures, MITO Technology, and Doral Energy-Tech Ventures also in the mix. Nestled inside Ternium’s steel complex—which already houses a direct-reduced iron plant—the setup is all about proving that on-site hydrogen production can power steelmaking, chemicals, or even heavy-duty transport, giving a big boost to industrial decarbonization in one of Mexico’s manufacturing powerhouses.

Project Overview

Tulum Energy tapped Scandinavian Energy Company to steer the EPC efforts, though they’re keeping the exact capacity under wraps. What’s clear is that it’s a modular, multi-megawatt-scale unit aiming for single-digit tonnes of hydrogen per day. Construction kicks off later this year, with commissioning penciled in for 2027.

The scope is pretty hands-on—everything from civil works and process integration with the steel plant’s utilities to setting up electric arc plasma systems from Tenova, plus the control systems to make it all tick. They’re also coordinating feedstock supply (hello, natural gas), hydrogen off-take for that adjacent DRI plant, and carbon handling. By piggybacking on existing infrastructure, they want to show you can shrink the footprint without reinventing the wheel.

In fact, Tulum Energy says this plant will take up to eight times less space than a comparable green-hydrogen electrolysis setup—though we’re waiting on an independent thumbs-up for that claim. In tight industrial parks where every square meter counts, a small footprint is a serious win.

Design and Technology

At its heart is an electric arc plasma reactor that blasts methane (CH₄) into a 1,500 °C+ oxygen-free zone for methane pyrolysis. The reaction splits methane into hydrogen (H₂) and solid carbon—no direct CO₂ emissions from the reactor itself. And by reusing electric arc furnace parts, Tulum Energy taps into established supply chains and proven engineering.

They’ve built it with modular reactor skids, gas–solid separators, and integrated heat recovery. Supposedly, the system can rival—or even beat—the energy efficiency of alkaline or PEM electrolysers, boasting up to five times better performance on a full-system basis. Skipping the electrical losses and water needs of electrolysis certainly helps. Plus, that solid carbon by-product—whether it ends up as graphite or carbon black—could open another revenue stream to soften operational costs.

Smart controls will track temperature, residence time, and gas makeup to guarantee hydrogen that’s feed-quality for DRI steelmaking or compression into existing pipelines. They’ll also run it continuously for months to uncover maintenance needs and test material wear—crucial intel for any future scale-up.

Regional and Industrial Context

Nuevo León isn’t your average industrial park—it’s one of Mexico’s heavy-industry powerhouses, packed with steel mills, auto plants, and high-tech manufacturers. Pesquería’s got plenty of natural gas, a sturdy grid, and engineers who know their stuff. For Ternium, having hydrogen on tap could seriously cut the carbon intensity of its DRI operations, aligning with steelmakers’ global net-zero goals.

Mexico is pushing hard on its energy transition, exploring hydrogen both as an export and a local feedstock. Although a dedicated regulatory framework for hydrogen is still taking shape, existing clean-energy incentives and gas networks give projects a solid head start. Local authorities in Nuevo León have been welcoming pilot projects, fast-tracking permits and hookups.

By co-locating with a heavyweight buyer like Ternium, Tulum Energy not only locks in an off-take partner but runs the pilot as a “live lab,” testing performance and costs in real-world conditions. That approach cuts the risk when you move from pilot to full-scale, part of building out the broader hydrogen infrastructure.

Strategic Implications

Bringing Scandinavian Energy Company on board lets Tulum Energy hand off EPC headaches to specialists while keeping its team laser-focused on process innovation and business scaling. It’s a familiar playbook for hydrogen startups—partner up to get things moving faster and trim down capital needs.

This pilot could shake up financial models for turquoise hydrogen, which sidesteps carbon capture hoops associated with blue hydrogen and avoids the land- and water-intensive aspects of green hydrogen. Investors will be watching to compare operating expenses, levelized costs, and IRRs against electrolysis-based projects in the US, Europe, and Asia.

On the demand side, nailing down early commitments from Ternium helps guarantee volumes. With more steel producers signing up for net-zero roadmaps, on-site low-carbon hydrogen might become a competitive edge—especially in spots where energy or water is at a premium.

Environmental and Economic Implications

Zero CO₂ emissions at the reactor gives it a clear environmental leg up over traditional steam methane reforming, which emits about 10 kg CO₂ per kg of hydrogen. That said, you’ve got to manage the upstream methane supply chain carefully to keep fugitive emissions in check. Top-notch leak detection and low-emission gas suppliers will be key.

Economically, selling both hydrogen and solid carbon is a smart dual-product play to boost returns. Carbon black’s a tried-and-true market, but high-value applications like graphene or specialty graphite could really pad the margin—assuming there’s enough demand and proper certification.

Smaller land use and modular builds could also mean lower upfront costs compared to sprawling electrolysis plants, which often face hefty civil work bills and grid upgrade prices. In tight industrial zones, saving on square meters can translate directly to cash saved.

Looking Ahead

As engineering gets rolling, Tulum Energy and SEC have their eyes on hitting milestones: mechanical completion, system commissioning, and a months-long test run to gather that all-important performance data. If all goes well, they’ll be ready to scale up to 20–200 tons per day.

In the end, this pilot’s success hinges on delivering reliable, cost-effective clean hydrogen at scale—pushing forward industrial decarbonization in Mexico and beyond. With solid carbon products adding a revenue cushion, it might just be one of the clearest routes yet to turning natural gas into low-carbon fuel—if the technology scales as promised and the hydrogen infrastructure evolves with it.
