Interview with Prof. Lars Grabow
Our guest on this episode of the podcast is Dr. Lars Grabow, professor of Chemical & Biomolecular Engineering here at the University of Houston. His research focuses on computational catalysis through which he gains tremendous understanding of various reaction systems and how catalytic reactions fundamentally work.
Computational catalysis is being used to discover new catalyst formulations. Improved catalysts leads to improved energy efficiency by increasing activity, improving selectivity and increasing catalyst life. Dr. Grabow talks about how a fundamental approach is used to find new alloys and reaction pathways faster than traditional experimental methods. He also talks about a non-steady-state operation that also increases catalyst activity, selectivity and life.

PACE is a financing program that's helping property owners finally move forward on energy and water efficiency projects for which traditional bank loans just don't work well. Dub walks Gary through how the program works, who it's for, and why the private capital behind it means no public dollars and no budget cycles, and how there’s a lot more flexibility. He also gets into some of the more surprising applications showing up on PACE's radar lately, including the infrastructure powering the data center boom here in Texas.
Episode 11: February 12, 2026
Interview with Margaret Cook
Gary is joined by Margaret Cook of HARC (the Houston Advanced Research Center) to discuss her article "Thirsty Data and the Lone Star State." This article examines the impact of data center growth on Texas water supply. Margaret explains that while much attention focuses on the massive power demands of data centers, water consumption is an equally critical concern. Cooling systems, particularly water-based heat rejection technologies, consume enormous amounts of water through evaporation, which, in other words, is water that never returns to the local watershed. With new facilities reaching hundreds of megawatts, the scale of that consumption is staggering. Margaret highlighted a troublingly large planning gap: data centers don't provide water usage forecasts, so they aren't actually being factored into Texas's state water plan. This means that communities may unknowingly be giving away water intended for future residents. Some of her recommendations to fix this include greater industry transparency, public–private partnerships for water infrastructure investment, alternative water supplies like brackish water desalination, and offsetting water use within the same watershed to achieve net zero or even net negative water impact.
Episode 10: January 30, 2026
Interview with Dr. Alan Rossiter
Gary sits down with Dr. Alan Rossiter, retired Executive Director at UH Energy, to discuss pinch analysis. Pinch analysis is a methodology for optimizing heat recovery in industrial chemical processes. Rather than relying entirely on external utilities like steam or cooling water, this analysis identifies how much heating and cooling can be handled through internal process heat exchange. Don't miss Dr. Rossiter's upcoming workshop on pinch analysis at the University of Houston Technology Bridge on March 5th!

Past Events:
- Energy Transition Webinar Series (January 27, 2026)
Gary talks with interns Hisham and Carla to recap a visit to the Houston Advanced Research Center (HARC) in The Woodlands, a "Living Lab" net zero building that tracks energy usage down to individual appliances and earned a 99/100 EPA Energy Star rating for seven consecutive years. Gary and Carla then dive into the second half of the hydrogen production article, this time focusing on electrolyzers instead of fossil fuels. Carla walks through the same two metrics used previously, which are first law energy efficiency and capital expenditure, applied to three electrolyzer types: alkaline, proton exchange membrane (PEM), and anion exchange membrane (AEM). Surprising to them, all three operate at similar efficiency, but differ in cost, durability, and compatibility with renewable energy sources.

Building from Episode 3 on October 30,2025, Gary and Hisham discuss an article Hisham and Carla wrote covering the energy conversion efficiency of hydrogen production from fossil fuels and their associated capital costs. Steam methane reforming, coal gasification and methane pyrolysis were assessed on those two metrics and they discussed whether these were good metrics to use when comparing these processes.
Episode 7: January 9, 2026
Interview
Our guest on the podcast is Dr. Michael Harold, professor of Chemical & Biomolecular Engineering here at the University of Houston. His research focuses on catalytic reaction engineering where he gains tremendous understanding of various reaction systems and how catalytic reactions fundamentally work.
Gary and Mike discuss the challenges, opportunities and energy efficiency associated with electrified steam methane reforming. His research focused on coiled wire heating, like that of a toaster oven, to provide the energy for heat electrically as opposed to providing energy by burning fuels. By using this method, many benefits such as energy efficiency and conversion improved, which is promising research for the future of steam methane reforming.

Carla and Gary discuss the way in which many published studies emphasize technical performance but provide insufficient energy balances, cost breakdowns, and process integration assumptions, limiting their relevance to industrial deployment. Credible efficiency claims must include capex and opex estimates, realistic equipment lifetimes, scalability limits, and sensitivity analyses, and not solely rely on laboratory or simulation-based results.
