Transforming Maritime Fuel with

Green Chemistry

A Scalable, Cost-Effective Solution for the Industry’s Fuel Challenges

Curve Energy’s proprietary green chemistry process provides a commercially viable and scalable alternative to the industry’s temporary, costly, and unsustainable solutions. Our patented low-energy, closed-loop desulfurization technology removes sulfur (including thiophenes), nitrogen, and vanadium from Heavy Fuel Oil (HSFO), upgrading it to IMO 2020-compliant Very Low Sulfur Fuel Oil (VLSFO) without relying on hydrogen-based desulfurization, blended fuels, or scrubbers.

Technology Process – How It Works

  • Energy-Efficient Processing

    Curve Energy’s chemical-based extraction process operates under near-ambient conditions (~45°C and 1–4 ATM), significantly reducing energy consumption and processing costs compared to conventional methods.

  • Comprehensive Pollutant Removal

    The process removes sulfur, NOx, vanadium, and particulate matter while also lowering CO₂ and CH₄ emissions, ensuring compliance with IMO 2020 and future regulatory standards.

  • Hydrogen-Free Technology

    Unlike conventional hydrogen-based desulfurization, Curve Energy’s process requires no SMR hydrogen, eliminating high carbon taxes, excessive energy costs, and reliance on hydrogen supply chains.

  • Seamless Integration & Scalability

    Designed as a modular Tank-to-Tank System, the process easily integrates into ports, bunker hubs, and refineries without the need for expensive infrastructure modifications, enabling rapid deployment and scalability.

Unlike existing alternatives, Curve Energy’s closed-loop system produces no harmful byproducts. Instead, it generates high-value thiophenes-enriched bitumen, creating an additional revenue stream while maintaining zero waste and ESG compliance.
