future of farming

Why this growing Chilean clean energy company moved its HQ to Houston

In Houston, air pollution is usually more of an abstract concept than a harsh reality. But in parts of Chile, the consequences of heating homes with wet wood are catching up to residents.

“Given all the contamination, there are times kids aren’t allowed to go to school. The air pollution is really affecting people’s health,” says Agustín Ríos, COO of Lignium Energy.

Additionally, the methane and nitrous oxide produced by cattle farming are a problem. But Lignium Energy, an international company started in Chile and now headquartered in Houston’s Greentown Labs, has a solution that can solve both problems by upending the latter.

“There’s a lack of solutions with the problem of manure. Methane gases are destroying our planet,” says CEO and co-founder Enrique Guzmán. He goes on to say that most solutions currently being developed are expensive and complex. But not Lignium Energy’s method, invented by co-founder José Antonio Caraball.

Caraball has patented an extraordinarily simple concept. Lignium separates the solid from liquid excretions, then cleans the solid to generate a hay-like biomass. Biomass refers to organic matter that can be used as fuel. What Lignium makes from the cattle evacuations is a clean, odorless and highly calorific biomass.

Essentially, Lignium combats greenhouse gasses with a green fuel that boasts an enviably low carbon footprint. “Our process is very cheap and very simple. That’s why we are a great solution,” explains Guzmán.

Caraball, an industrial engineer, came up with the idea six years ago, says Guzmán. Five years ago, he began working with the company, one year ago, Guzmán and Ríos picked up and moved to Houston.

“We decided to move out of Chile due to market size,” says Ríos. However, the product is already being sold to consumers in its homeland.

Why Houston? The reason was twofold. As an energy company, Ríos says that they wanted to be in “the energy capital of the world.” But Texas is also one of the largest sites of cattle farming on the planet. Lignium prefers to work with farms with more than 500 head to optimize harvesting the waste that becomes biomass.

With that in mind, Lignium has partnered with Southwest Regional Dairy Center in Stephenville, Texas, a little more than an hour southwest of Fort Worth, a town known as the world’s rodeo capital. The facility is associated with Texas A&M, though Guzmán says Lignium is not officially associated with the university.

Guzmán says that the company is currently hiring a team member to help Lignium figure out commercial logistics, as well as four or five other Houstonians who will help them take their product to market in the United States, and eventually around the globe. For now, he predicts that they will be able to sell to consumers in this country by early next year, if not the fourth quarter of 2023.

“We are very committed to the solution because, at the end of the day, if we do good work with the company, we are sure we can give better conditions to the cattle industry,” says Guzmán. “Then we can make a big impact on a real problem.

At the 20th annual Energy Tech Venture Forum presented by Rice Alliance for technology and Entrepreneurship, 11 startups scored recognition from the event's investors who evaluated over 90 early-stage energy transition companies.

"The selection process was both exhilarating and challenging given the incredible ideas we've seen today," says Jason Sidhu, director of information services business engagement at TC Energy, who announced the top companies. "I want to extend my gratitude to every company that participate din this year's Energy Tech Venture Forum. Your commitment to solving energy problems and pursuing ambitions ideas is truly commendable."

In addition to the top 10 most-promising companies, the event's attendees decided the people's choice pick out of the 50 or so pitching companies. The winner of that recognition was Calgary, Alberta-based Galatea Technologies, which has created a tech platform to enhance workflows for operational, financial, and environmental performance.

The top companies, according to the Rice Alliance experts and investors, were:

  • Circular economy startup, Polystyvert. Based in Montreal, the company has created a unique dissolution recycling process that creates a material that can contribute to cutting carbon emissions by up to 90 percent.
  • United Kingdom-based Miricoprovides a tracking technology to its customers to measure climate gases (like methane, carbon dioxide, nitrous oxide, and ammonia), across areas up to half a square mile and in all conditions.
  • ProteinEvolution, from New Haven, Connecticut, taps into a combination of green chemistry and enzyme technology to break down synthetic polymers.
  • Another Canadian company, Ayrton Energy, based in Calgary, created a liquid organic H2 carrier (LOHC) storage technology presents an opportunity for large, scalable and efficient transport of H2 over long distances.
  • Also representing New Haven, Connecticut, Carbon Loop is on a mission to make carbon capture and conversion scalable through carbon dioxide electrolysis using a proprietary catalyst to convert captured carbon dioxide into methanol.d
  • Based in London, Mobilus Labs has designed a new way for frontline communication with an in-helmet hardware and software solution. software solution designed for the frontline workforce.
  • 1s1 Energy, based in California, is working on producing low-cost green hydrogen by creating new materials to unlock unprecedented electrolyzer efficiency, durability, and more.
  • From Skokie, Illinois, Numat is specializing in solutions within Metal-organic framework (MOF) research to enhance the process of separating the hazardous chemicals negatively impacting human health and the environment.
  • Mantel, headquartered in Cambridge, Massachusetts, created a molten borate technology to capture CO2 in a new and efficient way.
  • The lone Houston-based company,Mars Materials is working to produce acrylonitrile using CO2 and biomass to enable decarbonization applications in carbon fiber and wastewater treatment.
