A roadmap for more water and energy, built around 3 untapped sources

Catalytic reforming can integrate wastewater treatment, heat recovery and hydrogen production

Catalytic Reforming Feature
In an oil refinery, catalytic reforming turns naphtha (a light petroleum liquid used as a gasoline starting material) and natural gas into gasoline and hydrogen. That hydrogen can support hydrocarbon reforming, which makes a variety of products the world is built on, demonstrating how reforming could be paired with wastewater treatment to utilize waste heat and produce valuable hydrogen.

Los Alamos National Laboratory researchers led a comprehensive survey of “wastewater reforming,” showing how pairing energy-intensive water treatment with hydrocarbon reforming could recover heat and convert dissolved organics into valuable hydrogen. Their work, published in Renewable and Sustainable Energy Reviews, flagged the toughest real-world contaminants and identified high-volume wastewater targets for scale-up.

Why this matters: Especially in arid regions, industries could cut freshwater demand and offset treatment energy by using wastewater to produce hydrogen for fuel cells, turbines or chemical manufacturing. 

What they did: The team reviewed catalytic reforming methods for wastewater, summarizing how common contaminants affect catalyst performance and lifetime. They highlighted three understudied feedstocks — oilfield wastewater, geothermal water and mining/mineral-processing wastewater — for future research. These are the most impactful but chemically complex proving grounds for wastewater-to-hydrogen systems.

How it works: Treating wastewater often uses a lot of heat. Because hydrocarbon reforming uses both water and heat to produce a hydrogen-rich gas, pairing it with wastewater treatment could capture that otherwise wasted heat and use wastewater as part of the process. This method turns a costly step into a way to make valuable hydrogen while reducing overall industrial waste.
