Powering the Future of Sustainable Fuels

Producing renewable and sustainable bio-methanol and e-methanol using proven, financeable technology — ready to deploy now.

Why ThermaFuels?

We're a project development company focused on execution, partnerships, and scale. Here's what sets us apart:

🎯 Development-First Mindset

We focus on getting projects financed, built, and operational—not just selling technology. Every decision is made with bankability and execution in mind.

⚡ Execution-Focused Approach

48-month timeline from FID to operations using proven, TRL-9 technologies. No development delays, no unproven systems—just reliable project delivery.​

🤝 Partner-Aligned Model

Flexible structures for off-takers, investors, and strategic partners. We adapt to your needs—whether equity participation, fuel supply agreements, or hybrid models.

📈 Experience-Driven Team

Multiple years of combined expertise in energy project development, execution, maritime operations, chemical engineering, and carbon markets. We've done this before.

🔄 Built for Scale

Repeatable platform designed for rapid deployment across multiple sites. First project in Texas is just the beginning of a multi-project pipeline.​

🌍 Strategic Site Selection

Multiple identified locations with excellent feedstock access, transportation infrastructure, and proximity to key markets. We're positioned where opportunity meets execution.

Why Sustainable Methanol & Why Now?

Real buyers are committing today — not in forecasts. Demand for sustainable methanol is contracted at the shipyard, driven by IMO mandates, and growing faster than supply can keep up.

Contracted Fleet Demand

200+

Methanol-capable vessels on order

Maersk, COSCO, CMA CGM, HMM and others have committed fleets — demand is contracted at the shipyard, not in forecasts.

Leading Decarbonisation Fuel

Up to 13%

of global marine bunker fuel by 2050

Methanol is now the leading near-term decarbonisation fuel for shipping under the IMO 2050 Strategy (Methanol Institute, 2026).

Rapidly Scaling Market

8 Mtpa → 250+

Sustainable methanol market, 2030 → 2050

From ~2.1 Mtpa today to ≥8 Mtpa by 2030 (industry pipeline); IRENA outlook to 250+ Mtpa by 2050 under accelerated decarbonisation.

Technology Strategy

Proven technology, deployed today.  |  Sustainable methanol — built around the buyer.

1. Proven Technology

Proven, financeable, ready

Biomass gasification, gas clean-up and methanol synthesis from technology partners with operating reference plants at the 100 ktpa class. No first-of-a-kind risk, no R&D delays — what we build has been built before.

TRL
9 across the full process train
FID to Ops
~36 months
Per-Site Capacity
~100 ktpa, modular
World-Class Licensors
Fully bankable project

Low-CI by design, not by retrofit

We pick sites where feedstock, logistics and offtake align — so low carbon intensity falls out of the design rather than being engineered in afterwards.

Feedstock
Sustainable woody biomass
Supply
Long-term agreement, single regional supplier
Target CI
Low 20s–30s gCO₂e/MJ (>70% reduction vs fossil)

2. Right Site, Right Feedstock

3. Built Around the Buyer

Designed against contracted demand

Our technology and site choices are made backwards from what our offtaker needs. The plant is sized, sited and certified to match a specific buyer’s spec — not a generic market.

Offtake
100% of first-plant capacity under LOI
Buyer
Top-tier global maritime bunkering (confidential)
Designed For
IMO well-to-wake & FuelEU Maritime compliance
Certification
Designed to meet ISCC EU and EU RFNBO standards

Strategy Update

ThermaFuels Realigns to Sustainable Methanol

ThermaFuels has sharpened its strategy around sustainable bio-methanol and e-methanol — fuels with contracted demand, regulatory tailwinds, and a clear path to certification.

Our technology and site choices are made backwards from what our offtaker needs. 100% of first-plant capacity is under LOI with a top-tier global maritime bunkering operator. Future milestones — licensor partnership, feedstock agreement, offtake announcement, and certification — will be published as they firm up.

Global Maritime Forum Report

Low-Carbon Methanol and Ammonia in Shipping

From pilots to practice: Methanol and ammonia as shipping fuels (Getting to Zero Coalition)


 This comprehensive report prepared by the Global Maritime Forum for the Getting to Zero Coalition introduces a new framework for assessing the maturity of scalable zero-emission fuels from 1) Proof of concept, reached once a fuel has been shown to be safe and effective in real-world demonstrations; 2) Initial scale, reflecting small-scale commercial adoption of the fuel on specific routes and ports; and 3) Maturity, marking the fuel’s development into a widely available solution, with limited barriers to uptake.

DNV White Paper

Methanol Fuel in Shipping

DNV White Paper,


 
 This paper from DNV, the world’s leading classification society and a recognized advisor for the maritime industry, examines the status of methanol as a marine fuel, addressing ships capable of using methanol as fuel, methanol fuel production, and the infrastructure that can supply them. It also discusses the potential way ahead for low-GHG methanol in the coming years and decades, highlighting the challenge of balancing supply and demand in light of the potential use of methanol as a GHG compliance strategy.
