A renewable-fuel pathway that converts fluctuating wind power into green hydrogen and combines it with carbon from agricultural biomass to produce green methanol for maritime shipping. The system is designed to absorb 100% of available wind power, reduce carbon emissions by more than 80%, and provide a scalable pathway toward zero-carbon marine fuels.

Maritime shipping remains heavily dependent on fossil fuels and is a major source of greenhouse gas emissions. As the International Maritime Organization works toward net-zero emissions around 2050, green methanol has emerged as a practical alternative because it can be used with existing ships and port infrastructure. This project proposes an integrated pathway that converts variable wind power and agricultural biomass into green methanol for maritime fuel applications.
Challenge
The production of green methanol requires reliable supplies of green hydrogen and a sustainable carbon source. At the same time, fluctuating renewable electricity can be difficult to use efficiently, while agricultural residues such as corn stover can create environmental problems when poorly managed or openly burned. The project addresses these challenges simultaneously by connecting renewable-energy utilization, biomass waste management and shipping decarbonization.
Solution and Innovation
Wind power is first used to produce green hydrogen through water electrolysis. Because wind generation fluctuates, the project uses large-scale electrolysis units designed to operate between 10% and 120% of rated load, with intelligent controls continuously adapting to changes in wind output. The system is designed to absorb 100% of the available wind power.
The resulting hydrogen is combined with syngas produced through the gasification of biomass such as corn stover. The gas mixture is adjusted before entering the methanol synthesis process, with subsequent purification producing marine-grade green methanol. Hydrogen storage and batteries help stabilize the process, while oxygen generated as a by-product can be used in steelmaking and wastewater treatment within the industrial park.
Expected Impact
The solution provides a pathway for converting variable renewable electricity and agricultural waste into a tradable, bunkering-ready low-carbon marine fuel. According to the project submission, the system aims to achieve 100% wind-power absorption and more than 80% carbon-emission reduction.
Beyond shipping decarbonization, the approach can reduce pollution associated with agricultural residue disposal and create additional value from rural biomass resources. The integrated system demonstrates how renewable electricity and agricultural waste can be converted into stable green chemical products.
Development and Scale-Up
The project is currently at the Pre-Pilot / Preparing for Field Testing stage and is seeking pilot partners to support real-world testing. The proposed model is designed for replication in regions with abundant wind and solar resources. Following validation, the platform could be expanded beyond green methanol to other green fuels and chemicals, including green ammonia and green methane, supporting broader decarbonization across shipping, aviation and chemical industries.
