An ancient New York marine discovery may hold the secret of hydrogen storage.
A small pocket of water from the ocean that covered New York State 390 million years ago was found hidden in the rocks.
Researchers published findings in the journal Earth and Planetary Science Letters on November 17, showing ancient water trapped inside framboids of ferropyrite, known for its raspberry-like resemblance. .
They were able to analyze what was inside the liquid pocket and were able to confirm that the salinity content of the water was consistent with the composition of the ancient ocean.
One of the far-reaching implications of this research is to gain more knowledge about how hydrogen fuels and other explosive gases can be safely stored underground or in rock. Hydrogen can be stored as a compressed gas, but it is highly explosive. It can also be stored as a liquid, but its low boiling point requires an incredibly low storage temperature of -252.882 °C or -423.188 °F.
Sandra TaylorThe lead author of the study and a scientist at the Department of Energy’s Pacific Northwest National Laboratory told Newsweek:
This study demonstrates the existence of small defects in minerals at the nanometer scale.
“We know that they can trap water and, by extension, likely hydrogen. It is important to consider what role
more effective hydrogen storage This could facilitate the use of cleaner fuels such as hydrogen fuel cells and nuclear fusion energy.
Researchers may also be able to use pockets of ancient oceans to learn more about ancient Earth’s climate and how it changed over time.
Daniel GregoryA geologist at the University of Toronto and co-author of the study told Newsweek:
We made this finding by analyzing the mineral pyrite and trying to understand whether the trace element content of pyrite affects the oxidation rate. After processing the data, things turned out to be more complicated than expected.
“We were using a natural pyrite sample that formed in the ocean hundreds of millions of years ago. What we found in the APT data was that the pyrite was probably formed in the ocean, and very small water droplets were present in the pyrite sample. It was saved in
“To follow up on this, I checked Ca [calcium]Mg [magnesium],vegetable [sodium]and K [potassium] Check if the concentration matches the seawater concentration. Na and K looked a little different than expected, but Mg and Ca were very close,” Gregory said.
This is important because Ca and Mg are used to determine past ocean temperatures.
“Therefore, we may have found a new tool for understanding Mg/Ca ratios through geological time. Pyrite is very common in the geological record, whereas current methods are This is important because it uses relatively rare evaporation deposits, and could lead to a deeper understanding of ocean and climate evolution over time.
Collecting information about the state of the ancient Earth will allow researchers to better understand how climate change affects life. The mineral content of the water, among other factors, gives clues as to sea temperature.
About 390 million years ago, it was during the Devonian Period, which lasted 60.3 million years, that water is believed to have become trapped in rocks. However, encountering liquid water that is millions of years old is rare, making it difficult to get a true picture of the environment.
Timothy Lyonsa professor of biogeochemistry at the University of California, Riverside and a co-author of the paper, told Newsweek.
Past ocean chemistry can usually only be inferred through indirect chemical means. This is because that water is not stored in the sample.
“These new discoveries are a surprising and potentially very significant way to track evolving ocean chemistry, and inferred changes in the atmosphere and life, much more directly through what appears to be trapped in tiny pockets of sea water.” If our initial interpretation is correct, this method extends up and down the geological timescale to reveal many long stretches of time about our past, and perhaps our future. You can find elusive answers.
