(Press-News.org) Consumer confidence in driving hydrogen-fueled vehicles could be improved by having station operators adopt a predictive model that helps them anticipate maintenance needs, according to researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Colorado State University (CSU).
Stations shutting down for unscheduled maintenance reduces hydrogen fueling availability to consumers and may slow adoption of these types of fuel cell electric vehicles, the researchers noted. The use of what is known as a prognostics health monitoring (PHM) model would allow hydrogen stations to reduce these unscheduled events.
“Motorists expect to be able to fuel their vehicles without any problems. We want to ensure motorists who drive hydrogen-fueled cars have the same experience,” said Jennifer Kurtz, lead author of the new paper, “Hydrogen Station Prognostics and Health Monitoring Model,” which appears in the International Journal of Hydrogen Energy. “This predictive model can let station operators know in advance when a problem might occur and minimize any disruptions that motorists might experience with hydrogen fueling.”
Co-authored by Spencer Gilleon of NREL and Thomas Bradley of CSU, the article posits the PHM model would improve station availability and consumer confidence.
The availability of hydrogen as a vehicle fuel is low compared to the ubiquity of gasoline, a fact reflected in the number of stations that dispense the low-emission fuel. While California has more than 10,000 gasoline stations, the Hydrogen Fuel Cell Partnership counts just 59 retail hydrogen stations across the state. With relatively few choices, motorists who rely on hydrogen must be confident their needed fuel is available. Station operators must make any necessary repairs to meet the demands of consumers, but they also must investigate the causes of any failures to avoid future problems.
Data from the National Fuel Cell Technology Evaluation Center reveals the single most common reason hydrogen stations shut down for unscheduled maintenance is problems with the dispenser system, which encompasses such items as the hoses and dispenser valves as well as the user interface. By using a data-based PHM, station operators could reduce the frequency of unscheduled maintenance and increase the frequency of preventive maintenance. The researchers have dubbed this particular PHM “hydrogen station prognostics health monitoring,” or H2S PHM.
The H2S PHM calculates the probability a component will continue working without a failure, based on how many fills the station has completed. The model can also be used to estimate the remaining useful life for each of the components, thereby lowering maintenance costs and making the stations more reliable. Using a hypothetical example, the researchers considered a dispenser valve that the H2S PHM has flagged as needing attention. The station operator can then be prepared for upcoming maintenance and schedule a technician to come when demand for hydrogen will be low. That cuts down on the amount of time a station would be unable to fuel vehicles. If the valve were to fail without warning, the station operator would have to call a technician, wait for their arrival and diagnosis of the problem, while at the same time be unable to provide fuel.
Kurtz, the director of NREL’s Energy Conversion and Storage Systems Center, noted that limitations exist when applying H2S PHM to the reliability of a hydrogen station. The method would not predict sudden failures, which can be caused by human error. The H2S PHM is also only as good as the available data, and more data is needed.

Training the gut’s immune system to combat detrimental effects of emulsifiers in processed food
In a new study, mice whose immune systems were trained against the microbial protein flagellin did not experience the usual detrimental effects of ingesting food additive emulsifiers, pointing to a potential new way to combat various chronic inflammatory diseases. Melissa Kordahi and Benoit Chassaing, Inserm researchers from the Institut Cochin and Université Paris Cité, France, and colleagues present these findings September 19th in the open access journal PLOS Biology. Dietary emulsifiers are substances added to processed food products to prevent mixed ingredients from separating. Prior research has suggested that eating certain emulsifiers ...
RNA for the first time recovered from an extinct species
A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses. The Tasmanian ...
New recipes for origin of life may point way to distant, inhabited planets
Life on a faraway planet — if it’s out there — might not look anything like life on Earth. But there are only so many chemical ingredients in the universe’s pantry, and only so many ways to mix them. A team led by scientists at the University of Wisconsin–Madison has exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life. Their ingredient list could focus the search for life elsewhere in the universe by pointing out the most likely conditions — planetary versions of mixing techniques, oven temperatures and baking times — for the recipes to come together. The process ...
STUDY: Cancer misinformation on TikTok could be harmful to women’s health
Millions of women are turning to the social media platform TikTok for health advice related to gynecologic cancers, but the majority of that information is misleading or dramatically inaccurate, according to a new study published by The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute in the journal Gynecologic Oncology. Senior study author Laura Chambers, DO, says this highlights the power of social media to feed misinformation that could be ...

$7 million in new grants propel Tufts Lyme research to next level
Researchers at the Tufts Lyme Disease Initiative recently received grants totaling more than $7 million to build on an already impressive array of discoveries that Tufts’ teams have made to combat tick-borne diseases. While Lyme disease can often be successfully treated with antibiotics, 10-20% of patients experience persistent fatigue, joint pain, and mental impairments that last months or years. For some, it is never clear whether symptoms signal persistent infection, reinfection, or malfunction by the body’s immune system. Researchers ...
Leading the way in global STI research
Researchers in the University of Delaware College of Health Sciences Department of Medical and Molecular Sciences are playing a pivotal role on the global health stage as they investigate the most common sexually transmitted infection (STI) in the world. Centers for Disease Control statistics show that 79 million Americans have human papillomavirus (HPV). With 14 million new infections each year, 80% of women will get at least one type of HPV at some point in their lifetime, according to the Office on Women’s ...
NIH releases strategic plan for research on herpes simplex virus 1 and 2
WHAT: In response to the persistent health challenges of herpes simplex virus 1 (HSV-1) and HSV-2, today the National Institutes of Health released the Strategic Plan for Herpes Simplex Virus Research. An NIH-wide HSV Working Group developed the plan, informed by feedback from more than 100 representatives of the research and advocacy communities and interested public stakeholders. The plan outlines an HSV research framework with four strategic priorities: improving fundamental knowledge of HSV biology, pathogenesis, and epidemiology; accelerating research to improve HSV diagnosis; improving strategies to treat HSV while seeking a curative therapeutic; and, advancing research ...
Early convalescent plasma use — helpful in avoiding severe COVID — also may lower long COVID risk
Findings from a nationwide, multicenter study led by Johns Hopkins Medicine and the Johns Hopkins Bloomberg School of Public Health suggest that patients with COVID-19 have less chance of developing post-COVID conditions — commonly known as long COVID — if they receive early treatment with plasma from convalescent (recovered) COVID patients that contain antibodies against SARS-CoV-2, the virus that causes COVID-19. The new research, first posted online today in mBio, a journal from the American Society for Microbiology, is a follow-up investigation to the 2021 clinical trial that showed convalescent plasma ...
