Climate change-focused multimedia company Climate Now announced this week that it will partner with the city of Houston and Rice University to host a Carbon Management Community Summit this fall.

The summit, sponsored by the U.S. Department of Energy, will be held at Rice University Bioscience Research Collaborative on November 16 and 17, and will feature interactive workshops and breakout learning sessions, as well as presentations and discussions from excerpts in the field. It will also be broadcasted virtually for those who cannot attend the event in person.

Key topics are set to include:

  • Carbon management technologies
  • The regulatory process for implementation and oversight
  • How to get involved in project development
  • How to minimize and mitigate risks
  • How to ensure that projects benefit local communities and workforce development

The summit will also focus on the DOE's plans to launch the Responsible Carbon Management Initiative, which aims to promote safety and accountability in carbon management projects, according to the department.

"The Department of Energy is committed to supporting carbon management opportunities that build on Houston's current initiatives while also ensuring that communities and other impacted stakeholders are at the center of those efforts,” Brad Crabtree, assistant secretary of Fossil Energy and Carbon Management at the DOE, said in a statement. “Ultimately, communities and stakeholders can become project partners whose ideas and concerns can improve project design and outcomes, and ensure that tangible economic and environmental benefits flow to affected communities.”

The event also aims to bring the community, industry leaders, government officials and educational institutions to the same table.

"“It is our responsibility to develop innovative technologies and practices that will reduce carbon emissions, and as we do this, we also have a responsibility to address environmental injustices and lift up communities that have been historically under-resourced,” Mayor Sylvester Turner added in the statement.

The event, which has registration open online, is free to attend, and a speaker list and agenda are slated to be announced in the coming weeks. Participants can attend one or both days of the event. A Spanish translation will be available onsite and virtually.

The Carbon Management Community Summit marks the second time Rice and the DOE have partnered on an energy innovation event. In July the DOE announced $100 million in funding for its SCALEUP program at an event for more than 100 energy innovators at the university.

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
