There was notable excitement around the opening of the Global Clean Energy Action Forum (GCEAF) Wednesday evening, Sept. 21. The three-day event drew members of the global energy community to Pittsburgh to share their ideas on how to move toward a clean and sustainable future. Carnegie Mellon University was a co-sponsor with the Department of Energy (DOE) in hosting GCEAF.

Carnegie Mellon University President Farnam Jahanian (pictured at lectern) welcomed hundreds of local and global top energy officials, CEOs and innovators to Pittsburgh at a reception held at the Heinz History Center. He recognized his fellow co-chairs on the Pittsburgh-based host committee that worked with the DOE to organize the event: Allegheny County Executive Rich Fitzgerald, Pittsburgh Mayor Ed Gainey and Allegheny Conference CEO Stefani Pashman.

"The imperative facing us could not be more urgent, and I would argue that, at this pivotal moment, there is no more fitting or inspiring place to hold these conversations than Pittsburgh," Jahanian said. "Over the past three decades, this region has reinvented itself as the center of a new economy — and a model for the power of innovation."

This first-ever event featured a high-level plenary, topical roundtables with energy and science ministers from 31 countries, CEOs and experts, expert panel discussions, technology demonstrations and pitches, and other activities, all focused on how to deploy clean energy technologies.

Before the public program kicked off Thursday afternoon, GCEAF attendees visited Mill 19, a former steel mill that now serves as a state-of-the-art research facility shaping the future of advanced manufacturing and sustainable practices. As part of the tour, guests attended several demonstrations related to manufacturing and sustainable practices:

• Azadeh Sawyer, assistant professor in building technology in CMU's School of Architecture, showed how she's using virtual reality to promote green building practices, allowing clients to explore how different design elements impact the user experience and energy efficiency.
• Sandra DeVincent Wolf, executive director of CMU's Manufacturing Futures Institute (MFI), showcased a robotic wire arc additive manufacturing process that uses less energy and reduces waste and costs compared to traditional manufacturing methods.
• The Advanced Robotics for Manufacturing (ARM) team showed participants how a robotic arm can quickly and efficiently inspect complex turbine blades for defects.

A panel of experts and venture investors heard from Pittsburgh-based energy and climate technology startups pitching their innovative technologies. Hosted by the DOE's Office of Technology Transitions, many of the entities taking part were spun out of CMU and/or led by CMU graduates or faculty. They included:

• CorePower Magnetics, a company using advanced materials and manufacturing to create finished power electronics components (inductors and transformers) to operate with increased temperature stability.
• Farm to Flame Energy, a biomass solution that allows for the burning of several agricultural wastes in a smokeless and odorless manner.
• LumiShield, co-founded by Hunaid Nulwala, who at the time was an assistant research professor of chemistry at CMU, which has developed a process to stop corrosion without relying on toxic solvents.
• Integrated Silicon Technologies, a company that has developed an innovative continuous process to reduce the cost of silicon-based solar electricity by a factor of two.

Several CMU faculty members, alumni, students and administrators took part in panels during both days of GCEAF.

CMU Professor of Engineering and Public Policy (EPP) and Co-Director of the Green Design Institute Paulina Jaramillo led a panel discussion on the recently launched Open Energy Outlook (OEO), an initiative that aims to examine U.S. energy futures to inform energy and climate policy efforts by applying the gold standards of policy-focused academic modeling, maximizing transparency and building a networked community. Katie Jordan, a Ph.D. student in EPP, presented the team's methodology and findings. The OEO is an initiative of the Wilton E. Scott Institute for Energy Innovation at CMU in partnership with North Carolina State University and funding from the Sloan Foundation.

Valerie Karplus, associate professor in EPP, took part in a session entitled "A High Road Energy Transition: Ensuring Fairness for U.S. Workers and Communities." The conversation included labor and nongovernmental organization leaders, all recognizing that different parts of the world are dealing with their clean energy transitions on different timelines. Karplus referenced the work of the Roosevelt Project, a research effort that examined the transitional challenges facing the Southwestern Pennsylvania region in making the transition to a future with net-zero greenhouse gas emissions as an effort to examine community impacts of decarbonization policies.
