Two Houston companies, Lummus Technology and Citroniq Chemicals, have paired up to build North American plants that produce green polypropylene.

Polypropylene is a thermoplastic used to manufacture items such as plastic packaging, plastic parts, medical supplies, textiles, and fibers. Green polypropylene is made from biomass.

Lummus and Citroniq say their first plant, set for completion in 2027, will produce 400,000 metric tons of green polypropylene each year. The plant will be at an undisclosed location in the Midwest.

In April, Lummus and Citroniq signed a letter of intent to develop Citroniq green polypropylene projects in North America using Lummus’ Verdenesuite of polypropylene technology. Their newly announced licensing and engineering agreements apply to the first of four planned facilities.

“This agreement demonstrates the progress we continue to make with Citroniq in establishing the first world-scale sustainable bio-polypropylene production process in North America,” Romain Lemoine, chief business officer for polymers and petrochemicals at Lummus, says in a news release.

“Combining Lummus’ leadership in polypropylene licensing with Citroniq’s carbon-negative production capabilities will help us meet the growing demand for bio-polypropylene and accelerate the decarbonization of the downstream energy industry,” Lemoine adds.

Citroniq says it’s investing more than $5 billion to expand its E2O process. The process produces carbon-negative plastics and hydrogen-and-carbon compounds called olefins from fully sustainable feedstocks. This eliminates the use of convention fossil-fuel hydrocarbons, Citroniq says.

Mel Badheka, principal and co-founder of Citroniq, says his company aims “to meet the market’s growing need for sustainable carbon-negative polypropylene at a competitive price.”

The global market for green polypropylene was valued at $123.5 billion in 2022, according to Grand View Research. Growth in the sector is being driven in part by the construction industry, the firm says.

As AI data centers gobble up more electricity, the Electric Reliability Council of Texas (ERCOT) — whose grid supplies power to 90 percent of Texas — has launched an initiative to help meet challenges presented by an increasingly strained power grid.

ERCOT, based in the Austin suburb of Taylor, said its new Grid Research, Innovation, and Transformation (GRIT) initiative will tackle research and prototyping of emerging technology and concepts to “deeply understand the implications of rapid grid and technology evolution, positioning ERCOT to lead in the future energy landscape.”

“As the ERCOT grid continues to rapidly evolve, we are seeing greater interest from industry and academia to collaborate on new tools and innovative technologies to advance the reliability needs of tomorrow’s energy systems,” ERCOT President and CEO Pablo Vegas said in a news release. “These efforts will provide an opportunity to share ideas and bring new innovations forward, as we work together to lead the evolution and expansion of the electric power grid.”

In conjunction with the GRIT initiative, ERCOT launched the Research and Innovation Partnership Engagement (RIPE) program. The program enables partners to work with ERCOT on developing technology aimed at resolving grid challenges.

To capitalize on ideas for grid improvements, the organization will host its third annual ERCOT Innovation Summit on March 31 in Round Rock. The summit “brings together thought leaders across the energy research and innovation ecosystem to explore solutions that use innovation to impact grid transformation,” ERCOT said.

“As the depth of information and industry collaboration evolves, we will continue to enhance the GRIT webpages to create a dynamic and valuable resource for the broader industry to continue fostering strong collaboration and innovation with our stakeholders,” said Venkat Tirupati, ERCOT’s vice president of DevOps and grid transformation.

ERCOT’s GRIT initiative comes at a time when the U.S. is girding for heightened demand for power, due in large part to the rise of data centers catering to the AI boom.

A study released in 2024 by the Electric Power Research Institute (EPRI) predicted electricity for data centers could represent as much as 9.1 percent of total power usage in the U.S. by 2030. According to EPRI, the share of Texas electricity consumed by data centers could climb from 4.6 percent in 2023 to almost 11 percent by 2030.

A report issued in 2024 by the federal government’s Lawrence Berkeley National Laboratory envisions an even faster increase in data-center power usage. The report projected data centers will consume as much as 12 percent of U.S. electricity by 2028, up from 4.4 percent in 2023.

In 2023, the EPRI study estimated, 80 percent of the U.S. electrical load for data centers was concentrated in two states, led by Virginia and Texas. The University of Texas at Austin’s Center for Media Engagement reported in July that Texas is home to 350 data centers, second only to Virginia.

“The U.S. electricity sector is working hard to meet the growing demands of data centers, transportation electrification, crypto-mining, and industrial onshoring, while balancing decarbonization efforts,” David Porter, EPRI’s vice president of electrification and sustainable energy strategy, said. “The data center boom requires closer collaboration between large data center owners and developers, utilities, government, and other stakeholders to ensure that we can power the needs of AI while maintaining reliable, affordable power to all customers.”
