EERC Welcomes Rob Klenner

The EERC is pleased to welcome back Rob Klenner to the EERC as a Principal Geoscientist. He will lead geological evaluations for CO2 enhanced oil recovery (EOR), CO2 storage, unconventional hydrocarbon recovery projects and geomodeling and simulation efforts. He holds a Master’s of Science and Bachelors of Science degrees in Geology from the University of North Dakota (UND).

It has been great working on projects that really impact the region. Conceptually testing technology is one thing; demonstrating its possibility is another. The state of North Dakota is fortunate to have an organization like the EERC exploring all the possibilities to keep North Dakota as an energy leader,” he added.

Prior to his return to the EERC, Rob was a Senior Geoscientist with Baker Hughes, a GE Company, where he was the reservoir analytics leader, creating subsurface machine learning solutions and services. Prior to that, he served as Lead Geoscientist with GE Global Research, where he was a key member of the team that initiated the reservoir program for their Oil and Gas Technology Center. Rob previously held the position of Geoscientist at the EERC, after having served as a Geophysicist Intern for Calpine Corporation at The Geysers, the world’s largest geothermal field.

Rob’s principal areas of interest and expertise include reservoir modeling, petrophysics, unconventional resources, petroleum geology, geothermal energy, machine learning, and commercialization of research and development. He has authored or coauthored publications in the fields of CO2 storage, EOR, geothermal energy, and machine learning solutions for upstream oil and gas.

It’s great to see the coordination of the greater organization and how everyone plays on the same team. This is a key strength of the EERC and has helped me fit in and feel welcomed,” Rob said.

Originally from Freeman, South Dakota, Rob met his wife, Anita, at UND. She works for Grand Forks Public Schools as a speech therapist. They have two children, a son who is 6 and a daughter who is 4. Both kids like to play soccer and basketball through the YMCA.

While Rob has long been an avid Vikings and UND hockey fan, the family also became OKC Thunder and OU Sooner fans while in Oklahoma.

We enjoy attending any family-friendly event in Grand Forks where we can get outside,” Rob said. “We also like to go to the park or walk/bike outside with our mini goldendoodle, Brix. When it’s raining, we enjoy staying inside baking and playing board games. We also enjoy camping and fishing out at Devil’s Lake.”

Rob said they look forward to visiting their families in Michigan, North Dakota, Minnesota, and South Dakota more frequently now that they live closer.

EERC Welcomes Rachael Perriello

EERC welcomes Rachael Perriello, Environment, Health, and Safety (EHS) Specialist. In this position, Rachael supports the ongoing efforts of the EERC’s EHS programs, which encompass hazardous materials and waste management, radiation, air pollution control, wastewater, storm water, and hazardous waste shipping as well as occupational health, safety, and process safety management.

Rachael was drawn to the EHS field early on. “My father and grandfather worked in factories when I was growing up and my work in labs made me passionate about preventing harm to employees and the environment,” she said.

Rachael holds a Master’s of Public Health in Environmental and Occupational Health from the University of Texas Health Science Center School of Public Health in Houston and a Bachelor’s of Science in Biology from the State University of New York at Stony Brook. Rachael previously worked as a contract Hazardous Materials/EESOH-MIS Specialist at the Grand Forks Air Force Base and as a Safety Officer at the Minneapolis Veterans Home before that.

“I’m proud to be working at the EERC, which is bringing novel and practical solutions to our industry partners,” she added. “I’m excited for the challenge of working in a research environment that’s often at the cutting edge of technologies, which will require me to research and adapt as we ensure both regulatory compliance and continuous improvement in our EHS programs.”

Originally from Connecticut, Rachael isn’t intimidated by Grand Forks winters, she’s actually looking forward to them.

“Three years living in Texas has made me very heat-avoidant!” she laughs. “I love the snow and going for a walk on a brisk, cold day, then warming back up with a mug of hot tea.”

Grand Forks appealed to Rachael and her husband because they were seeking a “balance of outdoors activities, ‘big city’ things to do, and small-town affordability and lifestyle.”

Rachael’s husband, Jacob, installs fire protection systems in facilities across Minnesota and North Dakota. They have three cats and a dog, enjoy going on backcountry camping and canoeing trips, and are currently restoring their 115-year-old house together, where Rachael’s woodworking skills are coming in very handy.

“I am a voracious reader and try to read at least 30 books a year,” she said. “I love sampling artisan ice cream, beer, and spirits in all of the different cities I visit.”

Department of Defense to Trial EERC Water-Saving Technology

When most people think of the U.S. Department of Defense (DoD), they probably don’t think of its huge office buildings or barracks first—if they think of them at all. Chris Martin, the EERC’s Senior Research Engineer for Advanced Thermal Systems, has been thinking about DoD’s buildings a lot lately and about all the water used to cool them, and he has a plan to change that.

Martin developed a new technology to address building cooling water consumption and was recently selected by DoD for a $1.8M award over the next 3 years to demonstrate the technology. This project is focused on improving the trade-off between water consumption and cooling efficiency in DoD’s wet cooling towers, which use large amounts of water to dissipate heat from various processes including building heating, ventilation, and air conditioning (HVAC) loads; data center cooling; power generation; and other industrial purposes.

Moving the cooling tower to the demonstration site.
The proprietary cooling technology to be evaluated is designed to optimize water use so that the benefits of wet evaporative cooling can be applied during hot summer afternoons, but the needless evaporation of water can be curtailed during cooler times when conditions allow for efficient and sensible heat transfer to the air.

DoD is the largest consumer of energy in the federal government, spending billions of dollars each year to power its military installations around the world. DoD is estimated to have 4000+ conventional wet cooling towers at its facilities, and each tower is a significant consumer of water: for example, one desert-based cooling tower at Ft. Irwin (one of the test sites for this project) has been estimated to consume up to 2.6 million gallons of water annually and produce almost 1.5 million gallons of concentrated wastewater for disposal. Water is a mission-critical resource that is scarce in many parts of the country. As threats to water and other energy resources increase, DoD’s energy planning is key to ensuring successful missions in the future.

Cooling towers are a common component of on-base infrastructure, and the sheer number of installed units suggests significant opportunity for technology replication across DoD if this technology is determined to be a cost-effective strategy for reducing water consumption.

Fully assembled cooling tower
Martin’s project involves field-testing two demonstration units at sites that are characterized by “hot, dry” and “moderate but humid” summer weather. Both sites are in California but represent two extremes that will provide strategic results when evaluating future replication at other DoD facilities. Ft. Irwin National Training Center in the California desert is among the most water-stressed facilities in the country. Out of necessity, it will need to be an early adopter of water-conserving technology. The second location, DoD Center Monterey Bay in Seaside, California, represents a moderate coastal California climate but is a location where water quality and availability are still a concern since the local supply relies on fragile groundwater aquifers. Combined results from Fort Irwin and Seaside will be extrapolated to estimate performance across the country, including the hot and humid southeast United States, home to many DoD facilities that might face increased water stress in the future.

“The underlying hypothesis of this new cooling technology is that savings in water consumption over time can result in a lower life cycle cost than with conventional wet cooling, which has a lower initial investment cost,” said Martin. To validate this hypothesis, the EERC will look at water savings, cooling efficacy, and operational costs over a yearlong trial.

The new cooling technology stems from prior work at the EERC, including projects funded by the U.S. Department of Energy (DOE) National Energy Technology Laboratory and DOE’s Advanced Research Projects Agency—Energy (ARPA-E) to develop a large-scale dry cooling alternative for thermoelectric power plants, which are the single largest users of fresh water in the United States.

“Reducing the intensity of water use during cooling will save money in the form of reduced operating costs, preserve limited fresh water for other purposes, and also enhance the security and resiliency of DoD’s mission by buffering critical operations like indoor environmental control from the unpredictable future of water availability and cost,” said Martin.
