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.To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

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!To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

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.To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

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.To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

Our guest on this episode of the podcast is Dr. Michael Harold, professor of Chemical & Biomolecular Engineering here at the University of Houston. His research focuses on catalytic reaction engineering through which 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. Mike’s research focuses 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.To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

Gary talks with Hisham about an article he wrote for the newsletter on the various pathways for hydrogen production and their energy efficiency. They talk about nine different colors denoting the different methods of producing hydrogen and compare their energy conversion efficiency. Hisham and Gary note that many novel methods lack consistent techno-economic and energy efficiency analysis. This requires further study for future articles and podcast episodes where we can compare costs, efficiency, and feasibility.To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

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.To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

Catalyst durability and true efficiency still need to be validated at industrial scale.To learn more about the Texas Industrial Energy Efficiency Program (TIEEP), go to https://www.uh.edu/energy/tiee/

Dr. Omar Abdelrahman, professor of Chemical & Biomolecular Engineering here at the University of Houston, is our guest on the podcast. His research focuses on thermal catalysis, electrochemistry, and photochemistry for chemical transformations.
