(Bloomberg)-Hydrogen capacity as a sham-changing climate solution is already suspicious of its high cost and lack of industrial demand. Yet one of the biggest concerns about gas is still not fully understood: how much hydrogen contributes to global warming?
Scientists in the US and Netherlands believe that they are still on the verge of nearest estimate of how much hydrogen is being inadvertently leaked from the infrastructure. The results will feed in the growing body of research how hydrogen can be a powerful, if indirect, greenhouse gas is due to a series of chemical reactions that occur when in the atmosphere.
The team, which is working with four industry partners, is using an innovative mobile device, which includes Shell PLC and Totalezes SE, designed to detect emissions from all hydrogen facilities from the price chain as well as the production sites to bus filling stations.
Unit – About the size of two stacked microwaves – by pumping it in the air and dries it, as it enters, allows any hydrogen to measure relatively easy, before converting water vapor to water vapor. The instrument created by Aerodine is about $ 150,000, currently only two existence.
Scientists using it say that it is the first viable measurement tool for detection of hydrogen in real -world scenarios.
Today, hydrogen leakage estimates anywhere more than 1% is more than 20%. For researchers, the goal is to better understand the main sources to avoid gas and reduce any problem in the bud as the newborn starts on the scale. What happened to Methane, which was leaking for decades, decided to take meaningful action at the United Nations COP26 Climate Summit in Glasgow.
Hydrogen can prolong the lifetime of methane in the atmosphere-a greenhouse gas is 80 times more powerful than the 20-year time limit-and in the upper environment, another powerful cause of global warming can promote the formation of water vapor. Taking various chemical reactions together, the global warming capacity of hydrogen is about 37 times compared to the CO2 in the horizon of 20 years.
“For hydrogen, we are still in the beginning. We are trying to prevent hydrogen emissions from becoming a problem,” said Tianani Sun, senior climate scientist at the Environmental Protest Fund, said, which is helping to sponsor the project.
The study, which should be prepared for a peer review by the middle of next year, comes as, as politicians placed the policies required to score hydrogen extensively, especially in the industry. The European Union wants 20 million tonnes per year by 2030, out of which half will import from abroad, opening heavy capacity for leaks with the supply chain.
“The challenges of the hydrogen economy are becoming more pronounced,” said Thomas Rockman, Professor of Atmospheric Physics and Chemistry at the University of YouTract, working on the project. He began measurements at a bus refilling station in the north of the Netherlands last week. “We are a little blind.”
