(Press-News.org) An international team of scientists has discovered a way to store and release volatile hydrogen using lignin-based jet fuel that could open new pathways for sustainable energy production.
In a new study in the International Journal of Hydrogen Energy, Washington State University Professor Bin Yang and colleagues demonstrated that a type of lignin-based jet fuel they developed can chemically bind hydrogen in a stable liquid form. The research has many potential applications in fuels and transportation and could ultimately make it easier to harness hydrogen’s potential as a high energy and zero emissions fuel source.
“This new, lignin jet fuel-based technology could enable efficient, high-density hydrogen storage in an easy-to-handle sustainable aviation fuel, eliminating the need for pressurized tanks for storage and transport,” Yang said.
For the study, researchers at WSU, Pacific Northwest National Laboratory, the University of New Haven, and Natural Resources Canada set out to address one of the major challenges with using hydrogen as a fuel source. The lightest element’s low density and explosive nature make storage and transport technically challenging, inefficient, and expensive.
The January article details how the research team discovered the new hydrogen-storing process using chemical reactions that produced aromatic carbons and hydrogen from lignin jet fuel—an experimental fuel developed by Yang’s lab based on lignin, an organic polymer found in plants.
“Hydrogen is a versatile energy carrier that could help the U.S. meet its targets for zero-emission mobility, integration of renewables, and decarbonization of industry,” Yang said.
The discovery points to new uses for the lignin jet fuel developed at WSU by Yang, who previously tested a new continuous process that creates the fuel from agricultural waste. Experiments have shown that the sustainably produced fuel could increase engine performance and efficiency while dispensing with aromatics, the pollution-causing compounds found in conventional fuels.
“This innovation offers promising opportunities for compatibility with existing infrastructure and economic viability for scalable production,” Yang said. “It could help create a synergistic system that enhances the efficiency, safety, and ecological benefits of both sustainable aviation fuel and hydrogen technologies.”
Next, WSU researchers will collaborate with scientists at the University of New Haven to design an AI-driven catalyst that enhances and completes the reactions, making them more efficient and cost-effective.
Funding for the work came from the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy and its Hydrogen and Fuel Cell Technologies Office.

Electrochemical x-ray scattering unlocks secrets of redox enzymes
2025-01-27
Redox enzymes are proteins that catalyze oxidation-reduction reactions, which involve the transfer of electrons between molecules. Redox enzymes are crucial in bioelectrochemical devices, such as biosensors or biofuel cells. For instance, biosensors catalyze reactions that convert biochemical signals into measurable electrical signals, enabling the detection of substances like glucose. In biofuel cells, redox enzymes convert biological energy into electricity, powering small devices like medical implants. Their ability to facilitate the efficient transfer of electrons between molecules makes them indispensable ...
Unveiling Japan's geological history through volcanogenic massive sulfide deposits
2025-01-27
The Earth’s surface is constantly reshaped by the movement of tectonic plates, which make up the continental crust on which we are living. These tectonic plates are in continuous motion, and when one plate is pushed under another, it is called “subduction.” These processes play a crucial role in shaping the Earth’s landmasses, including the islands of Japan, over several hundred million years. Studying ancient mineral deposits offers a valuable way to uncover the timing of these events. However, determining the precise timing of these tectonic events has ...
Unraveling the connection between Canadian wildfires and arctic ice clouds
2025-01-27
Clouds, composed of tiny water droplets or ice crystals, play a vital role in regulating Earth’s climate by influencing the amount of solar radiation that reaches the surface. The cloud phase significantly impacts the surface energy balance as liquid water clouds reflect more radiation than ice clouds. Ice clouds typically form at temperatures below −38°C, but recent observations indicate their formation at higher temperatures in the Arctic. This phenomenon is facilitated by ice-nucleating particles (INPs), including mineral dust, organic aerosols and bioaerosols, which promote ice cloud formation above the usual freezing ...
Delayed REM sleep could be an early sign of Alzheimer’s
2025-01-27
Scientists have recently shown that both the quality and the amount of sleep we get may influence our risk of developing Alzheimer’s disease.
Now, a study suggests that people who take significantly longer to start the dream phase of sleep, known as rapid eye movement (REM), may be experiencing an early symptom of the disease.
REM follows three phases of non-REM sleep, each deeper than the last. The four phases take 90 minutes or more to complete, depending on age, and a person may cycle through them four or five times in a typical night. Older people take longer to reach REM.
During REM sleep the brain processes memories, ...

Heart disease remains leading cause of death as key health risk factors continue to rise
2025-01-27
Highlights:
According to the American Heart Association’s 2025 Heart Disease and Stroke Statistics Update, heart disease remains the leading cause of death in the U.S.
While medical advances have helped more people live longer with cardiovascular diseases, many of the risk factors which lead to these diseases, including high blood pressure and obesity, continue to grow at alarming rates.
Cardiovascular diseases, including heart disease and stroke, claim more lives in the U.S. than all forms of cancer and accidental deaths – the #2 and #3 causes of death – combined.

Preterm babies receive insufficient pain management
2025-01-27
A large proportion of babies born very early need intensive care, which can be painful. But the healthcare system fails to provide pain relief to the full extent. This is shown by the largest survey to date of pain in neonatal care, now published in the journal Pain.
Every day for 4.5 years, neonatal care staff have recorded the occurrence of pain, the causes of pain, and how pain is assessed and treated in premature babies in Sweden. The study covers 3,686 babies born between 22 and 31 weeks of gestation from 2020 to 2024. The total observation time was just over 185,000 days of care. Data were collected in the Swedish ...
Does historic redlining—a form of structural racism—affect survival in young people with cancer?
2025-01-27
A recent study indicates that children and young adults with cancer face an elevated risk of dying if they live in previously redlined neighborhoods—residential areas marked in the 1920s–1930s by lenders as undesirable for mortgage loans due to their racial demographics. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
Historic redlining prevented Black households and other communities of color from accessing home mortgages for many years, leading to economic disadvantage and racial ...
How animal poop helps ecosystems adapt to climate change
2025-01-27
Climate change is melting away glaciers around the world, but in the Andes Mountains, a wild relative of the llama is helping local ecosystems adapt to these changes by dropping big piles of dung.
This finding, published Dec 30 in Scientific Reports, revealed that the activity of this animal could accelerate the time plants usually take to establish on new land by over a century, highlighting a surprising way organisms are adapting to climate change.
“It’s interesting to see how a social behavior of these animals ...
Over 1/3 of parents say their child has experienced dental problems that reflect oral hygiene habits
2025-01-27
More than one in three parents say their child has faced issues like tooth decay, cavities, stained teeth, gum concerns or tooth pain over the past two years, a national poll suggests.
And these problems were linked to children’s oral care routine, more commonly experienced among those who skipped dental hygiene recommendations or followed them less often, according to the University of Michigan Health C.S. Mott Children’s Hospital National Poll on Children’s Health.
“Maintaining oral health from a young age, including regular brushing ...
