Chile Adds Green Hydrogen to Gas for 4,600 Homes

In the coastal cities of La Serena and Coquimbo, Chile, about 4,600 families are making history every time they turn on their stoves or hot water heaters.

Gas company GasValpo is now blending 10% green hydrogen into the natural gas flowing through residential pipelines. Families haven't noticed any difference in how their appliances work, and their gas bills remain the same.

The project started small, mixing just 3.5% green hydrogen into the natural gas supply. After installing an electrolyzer that splits water into hydrogen and oxygen, the company increased the blend to 5%, then 10%. By the end of 2026, they plan to reach 15%.

The ultimate goal is ambitious: an 80% natural gas, 20% hydrogen mix that would eliminate 340 tons of CO2 emissions every year. That's equivalent to taking dozens of cars off the road permanently.

Regional Energy Secretary Fabián Páez visited the facility to see the innovation firsthand. He emphasized that the Coquimbo Region already leads in renewable energy development, making it the perfect testing ground for this technology.

"This eliminates carbon emissions while helping stabilize gas prices because they don't use petroleum-derived gas," Páez explained. For families, that means cleaner air and more predictable household costs.

The Ripple Effect

This pilot project is being watched closely across South America. The University of La Serena is monitoring everything from how the hydrogen interacts with existing gas pipes to the quality of combustion in home appliances.

Jorge Briceño, the project manager at GasValpo, described the company's pride in producing and injecting hydrogen that reduces pollution "when our customers are cooking or showering in the morning." The hydrogen is manufactured, stored, and blended on-site.

The real breakthrough isn't just the technology. It's proving that transitioning to cleaner energy doesn't require people to buy new appliances, change their routines, or pay more money. The infrastructure they already have works perfectly fine.

Other South American cities struggling with air quality and carbon reduction goals are now paying attention. If Chile can blend green hydrogen into existing gas networks seamlessly, the model could spread across the continent.

Thousands of Chilean families are quietly helping prove that the clean energy transition can be invisible, affordable, and immediate.
