Transforming High-Sulfur Fuel into Cleaner Energy at Scale
Curve Energy converts high-sulfur fuel oil into IMO-compliant low-sulfur fuel using a patented, low-energy process designed for global bunker markets.
Company Overview
Fueling a Cleaner
Future Today
Curve Energy is a clean-fuel technology company modernizing how the maritime industry meets sulfur and emissions standards. Our patented green-chemistry process removes sulfur, nitrogen, vanadium, and other contaminants under near-ambient conditions, producing stable VLSFO without hydrogen, extreme heat, or costly refinery infrastructure.
We deliver a scalable, modular solution that helps ports, refiners, and fuel suppliers reduce emissions while improving margins.

Global Market Context
The Marine Market Opportunity
Marine fuel economics are under pressure from persistent HSFO–VLSFO price spreads, rising carbon and compliance costs, and the poor scalability of existing fuel treatment solutions, driving growing cost uncertainty across refiners, bunker hubs, and shipping operators.
Target Market
40M
Megatons / year
Near-term commercial focus targets approximately 40 million metric tonnes per year, where fuel economics and operational fit support early adoption.
Serviceable Market
157M
Megatons / year
Curve’s serviceable market spans approximately 157 million metric tonnes per year, where upgrading and sulfur compliance are economically viable.
Total Market
250M
Megatons / year
Global marine fuel demand totals approximately 250 million metric tonnes per year, representing a $150B market today and nearly $200B by 2034.
The Future of Clean Marine Fuel
The Curve Energy Solution
Curve Energy’s patented green chemistry desulfurization process upgrades Heavy Fuel Oil (HSFO) to Very Low Sulfur Fuel Oil (VLSFO) under near-ambient conditions by removing sulfur at the molecular level. The hydrogen-free process produces IMO-compliant fuel with a low carbon footprint.
Proprietary Technology
Protected under an international PCT application, with patents issued in the United States, Malaysia, and Saudi Arabia, and national phase filings advancing across key jurisdictions.
De-Risked & Market-Ready
Designed for scalable operation, low treatment costs, and long-term regulatory and commercial durability.
