SwRI expands Metering Research Facility capabilities for hydrogen research and testing

Upgraded testing capabilities ensure natural gas infrastructure is compatible with hydrogen blends

2025-11-11

(Press-News.org) SAN ANTONIO — November 11, 2025 — Southwest Research Institute (SwRI) has expanded the capabilities of its world-class Metering Research Facility (MRF) to ensure existing natural gas infrastructure is compatible with hydrogen fuels. This initiative is supported by internal funding and combines SwRI’s expertise in energy, power, and automotive engineering to help several industries evaluate how blending hydrogen with natural gas affects infrastructure and technology.

“Blending hydrogen into natural gas pipelines could prove to be a promising, cost-effective pathway to reduce greenhouse gas emissions using existing natural gas infrastructure,” said MRF Manager Adam Hawley, one of the initiative’s leaders. “The industry is studying using hydrogen-natural gas blends to generate electricity and in-home appliances such as heaters and ovens without impacting equipment or performance. SwRI’s goal is to have a research test bed to support these activities.”

As part of this development, the team repurposed a gas loop within the MRF, which was previously used to study flow measurement and compression for low-pressure natural gas applications. These enhancements now enable the facility to test hydrogen-natural gas blends and explore their effects on pipeline systems, components, and flow measurement technologies.

“SwRI originally designed the MRF to accurately measure natural gas flow, and we’ve now adapted the facility to include hydrogen,” said SwRI Assistant Program Matthew Godush, one of the project’s leaders. “This leverages years of research and infrastructure already in place.”

The upgraded facility now features a hydrogen injection system, which introduces hydrogen into the natural gas stream, along with other compatibility upgrades. These include a new safety system to detect both hydrogen and natural gas leaks. The upgraded system can simulate transmission, distribution, and end-use scenarios for natural gas-hydrogen blends.

The facility will focus initial studies on blends of natural gas with 5 to 25 percent hydrogen, pursuing both internal and client-funded research to understand how introducing hydrogen affects existing energy infrastructure.

It will also offer flow measurement testing, endurance testing, gas analysis, component compatibility analysis, leak detection, and general component testing to clients.

“Our goal is to show, through testing and research, the process needed to upgrade natural gas infrastructure to accommodate hydrogen,” Godush said. “Right now, hydrogen production is limited by its use, but demonstrating the efficiency and feasibility of these applications creates a large and economically viable case for hydrogen as a reliable fuel source.”

SwRI continues to dedicate a multidisciplinary team to hydrogen energy research initiatives, supporting efforts to decarbonize a broad spectrum of industries.

Widely cited stat on global water and food security ‘hearsay’ and fragile for policymaking

2025-11-11

A globally cited statistic about the role of irrigation for food security that has formed foundational evidence for policy making and scientific research is used on a ‘hearsay’ basis and is based on weak evidence, according to a new study. In a new paper published in PNAS Nexus, a team of researchers from the University of Birmingham has analysed the use of widely cited statistics, that irrigation agriculture produces 40% of global crops and withdraws 70% of global freshwater resources. ...

Forever chemicals affect the genes of unhatched ducklings

2025-11-11

The EU is considering introducing a blanket ban on the man-made chemicals called PFAS because of the risks they pose. Researchers have now found that these substances can even alter the genes of birds before they hatch. These substances are called ‘forever chemicals’ because they break down very slowly in the natural environment. Some people may know them by the abbreviation PFAS, which stands for per- and polyfluoroalkyl substances. They are also very abundant. “These substances are used in hundreds of products, ranging from frying pans and waterproof clothing to firefighting foam, food packaging and stain-resistant ...

American Pediatric Society announces election of 2026 members

November 11, 2025 – The American Pediatric Society (APS) is pleased to announce the election of 92 new members to its distinguished community. Founded in 1888, APS is North America's first and most prestigious academic pediatric organization. New members will be formally recognized at the APS Howland Gala, held during the Pediatric Academic Societies (PAS) 2026 Meeting in Boston, April 24–27, 2026. APS members are recognized child health leaders of extraordinary achievement who work together to strengthen academic pediatrics by expanding the workforce, nurturing leaders, ...

A fix for frost: Engineers use electricity to zap ice without heat or chemicals

2025-11-11

During winter months, frost can unleash icy havoc on cars, planes, heat pumps, and much more. But thermal defrosting with heaters is very energy intensive, while chemical defrosting is expensive and toxic to the environment. Jonathan Boreyko, associate professor in mechanical engineering at Virginia Tech, and his research team may have found a new and improved method for deicing. His philosophy is to combat ice by exploiting its own physics instead of using heat or chemicals, creating methods of frost removal ...

The growing crisis of chronic disease in animals

2025-11-11

Herdon, Va., November 11, 2025 - From dogs and cats to dairy cows and sea turtles, animals around the world are suffering from various cancers, obesity, diabetes, and degenerative joint disease. Understanding the forces driving an increase in these non-communicable diseases (NCDs) chronic diseases is vital for both animal and human health. However, interdisciplinary research on NCDs in animals is lacking. A Risk Analysis study introduces an innovative conceptual model for improving the surveillance and management of these chronic animal diseases. Developed ...

Clinical characteristics and outcomes of portal vein thrombosis in patients with porto-sinusoidal vascular disease

2025-11-11

Background and Aims Portal vein thrombosis (PVT) frequently occurs in patients with porto-sinusoidal vascular disease (PSVD), but its clinical characteristics and outcomes remain poorly understood. This study aimed to investigate the clinical features and outcomes of PVT in PSVD. Methods A total of 169 patients with PSVD confirmed by hepatic histology were included. PVT was diagnosed using contrast-enhanced magnetic resonance imaging or computed tomography. Demographic, clinical, and laboratory data, portal hypertension-related complications, comorbidities, and mortality were collected and compared between patients with and without PVT. The primary ...

Two major irrigation statistics may be wrong

2025-11-11

The idea that irrigated agriculture underpins global food and water security—producing 40% of crops and using 70% of freshwater—has become widespread in science and policy. However, these statistics are not empirically supported, according to a new analysis. Arnald Puy and colleagues traced these figures through citations in 3,693 scientific documents published from 1966 to 2024. The authors found that 60–80% of citation paths led to sources without supporting data or that did not contain the claimed numbers. Only approximately 1.5% of cited documents provided original data. When ...

A database, collecting and classifying tile-like patterns in biology, aims to be a resource and research catalyst. The human eye is drawn to the rhythmic beauty of tiled patterns, which occur abundantly in nature. Jana Ciecierska-Holmes, John Nyakatura and Mason Dean led a project with colleagues, offering a classification of biological tilings—repeated patterns of geometric discrete elements found in nature. Tilings are found across the tree of life, in a wide variety of taxa and at many spatial scales from ...

Research alert: GLP-1 drugs linked to dramatically lower death rates in colon cancer patients

2025-11-11

A new University of California San Diego study offers compelling evidence that glucagon-like peptide-1 (GLP-1) receptor agonists — the class of drugs behind Ozempic, Wegovy and Mounjaro, for example — may do more than regulate blood sugar and weight. In an analysis of more than 6,800 colon cancer patients across all University of California Health sites, researchers found that those taking GLP-1 medications were less than half as likely to die within five years compared to those who weren’t on the drugs (15.5% versus 37.1%). The study, led by Raphael Cuomo, Ph.D., associate professor in the Department of Anesthesiology ...
