Houston startup secures $5M to turn oilfield wastewater into critical minerals

fresh funding

Houston-based startup Altillion has secured $5 million in seed funding to accelerate the commercialization of its proprietary IRIS and ALIX technologies, which convert oilfield-produced water into valuable minerals.

San Francisco-based EIC Rose Rock and Houston-based Flathead Forge led the round. Altillion says the funding will go toward pilot facilities and commercial deployments as the company looks to scale in the U.S.

“Altillion’s efficient and scalable technologies are needed more than ever to reshape critical mineral recovery and facilitate beneficial use of oilfield brines,” Jay Keener, Altillion’s CEO and co-founder, said in a news release. “We’re uniquely positioned to provide a stable, domestic supply of the critical minerals needed for electronics, batteries, healthcare and national defense technologies. This investment from EIC Rose Rock and Flathead Forge enables us to strategically accelerate this impact and is very timely given the current geopolitical dynamics.”

Altillion's IRIS and ALIX platforms extract minerals like iodine, lithium and copper from oilfield-produced water, geothermal brines and salars. This process allows companies to unlock new sources of revenue while also boosting the domestic critical minerals supply chain. The company announced earlier this summer that it will launch a feasibility project in the Permian Basin and aims to develop a path to commercial-scale implementation in the field.

“We are excited to partner with Altillion to scale and deploy these world-class technologies to access the vast wealth hidden in wastewater,” David Clouse, Managing Director of EIC Rose Rock, added in the release. “With Altillion, we’re expanding our ability to empower the energy industry to domestically source the critical minerals America needs for a robust economy and supply chain.”

Altillion was founded by Keener and COO Scott Buckwald in 2023. Keener previously founded KDH Trading, where Buckwald also serves as COO, according to his LinkedIn page.

Houston's KBR to provide tech for Singapore SAF plant

SAF agreement

Houston engineering and technology contractor KBR has been picked as the technology provider for what’s expected to be Asia's first commercial-scale ethanol-to-jet sustainable aviation fuel (SAF) plant.

The proposed plant on Jurong Island in Singapore is being developed by Keppel Ltd.’s Infrastructure Division and Aster Chemicals and Energy. KBR will provide technology licensing and Front-End Engineering Design (FEED) services based on its PureSAF technology.

The plant has a planned production capacity of up to 100,000 tons of SAF per year. The plant is subject to final investment decisions and regulatory approvals.

“We are looking forward to working with Keppel and Aster on this key project and to support Singapore’s ambition of becoming Asia’s leading SAF hub and advancing the ongoing efforts to decarbonize the country’s aviation ecosystem,” Stuart Bradie, KBR president and CEO, said in a news release.

According to KBR, its PureSAF Technology can process multiple feedstocks like bioethanol, syngas, carbon dioxide and hydrogen and convert them to SAF, diesel and gasoline.

The technology was developed by Swedish Biofuels AB and commercialized by KBR.

“KBR’s PureSAF is a feedstock-flexible, bankable technology that is designed to deliver a 100% drop in jet fuel, ready to power aircraft without blending,” Bradie added in the news release. “We are constantly innovating our SAF solution to make it compatible with feedstock availability in different regions and to enable the aviation industry to transition to low-carbon jet fuel with a cost-optimized approach.

KBR has also entered into a memorandum of intent with Keppel’s Infrastructure Division, which states that the companies will collaborate again on decarbonization efforts across biofuels, plastic recycling, digitalization via AI, and SAF.

KBR announced in October that it would spin off its Mission Technology Solutions business, nicknamed SpinCo. The scaled-down KBR, nicknamed RemainCo, would concentrate solely on sustainability technology and services designed to reduce carbon emissions and support energy transition efforts. SpinCo named its new CEO and CFO earlier this month.
