Solar-powered production of hydrogen and methanol from wastewater and CO2 for chemical industries

energyTestedTRL 4

Imagine a leaf that doesn't just grow, but turns sunlight, dirty water, and air pollution into fuel. This technology mimics that process to create clean energy sources like hydrogen and methanol. It uses special materials and sunlight to power the chemistry, replacing expensive electricity or fossil fuels.

The business problem

What needed solving

Chemical industries struggle to integrate renewable energy into their high-heat and high-energy processes, remaining dependent on natural gas and facing high CO2 emissions.

The solution

What was built

A photoelectrochemical (PEC) system using earth-abundant catalysts and perovskite PV cells to produce hydrogen and methanol from CO2 and wastewater.

Who can put this to work

Chemical Manufacturing
enterprise
Target: Industrial chemical plant

If you are a chemical plant dealing with high energy costs and CO2 emissions — this project developed a photoelectrochemical system that turns wastewater and CO2 into hydrogen and methanol. This allows your facility to become more self-sufficient by producing its own energy vectors on-site.

Heavy Industry
enterprise
Target: Metal smelting facility

If you are a smelting company dealing with high natural gas consumption in melting furnaces — this project developed a way to produce hydrogen via artificial photosynthesis. You can use this hydrogen as an alternative fuel source to eliminate CO2 emissions from your furnaces.

Energy Generation
mid-size
Target: Renewable energy provider

If you are an energy provider dealing with the inefficiency of solar-to-fuel conversion — this project developed tandem PEC cells and perovskite PV integration. This maximizes the solar-to-fuel (STF) efficiency to create storable liquid and gas energy carriers.

Frequently asked

Quick answers

What is the estimated cost or price of the system?

Based on available project data, specific pricing is not provided, but the project focuses on using earth-abundant materials and optimizing CAPEX through a new way to concentrate light on the semiconductor surface.

Can this be scaled to an industrial level?

Yes, the project plan includes moving from catalyst study to prototypes and then scaling up to pilots with tandem PEC cells to assess industrial feasibility.

How is the intellectual property or licensing handled?

Based on available project data, there is no specific information regarding IP or licensing agreements provided in the summary.

How does this integrate into existing industrial infrastructure?

The system integrates by using local resource streams like CO2 emissions and wastewater as feedstocks and providing fuels that can be tested in existing engines and melting furnaces.

What is the timeline for implementation?

The project period runs from 2023-09-01 to 2027-08-31, during which it will progress from material research to pilot scale-up.

Consortium

Who built it

The consortium is heavily weighted toward industrial application, with 8 industry partners (including 4 SMEs) representing 47% of the 17 total members. This strong industry presence, combined with 6 research centers and 3 universities across 8 countries, suggests a high focus on commercial viability and practical scale-up rather than purely academic research.
