However, this can be prevented if we find an environmentally friendly & sustainable way to produce hydrogen. These gases are exacerbating the climate crisis our planet is going through. A revealing report from the US Department of Energy revealed that natural gas plants were the sources of 95% of the hydrogen produced in the country.Īs a result of these fossil fuel driven hydrogen production processes, large amounts of greenhouse gases are released into the atmosphere. However, the question remains: where does this hydrogen come from? Although hydrogen is one of the cleanest sources of energy, most of the hydrogen we produce today is still derived from and relies on fossil fuels. Secondly, it is about technology for energy conversion, i.e. “First, some effort is needed to ensure that existing gas infrastructure can process hydrogen instead of natural gas. He further noted that this research is about storage & distribution of gaseous fuel. Furthermore, there are no CO2 emissions associated with this energy production,” Assadi added. The big benefit, however, is being able to use the infrastructure that is already exists.
“The efficiency of operating the gas turbine with hydrogen will be somewhat less. His team has now shown that it can use hydrogen in existing natural gas infrastructure without changing much of the initial composition of structures. Nobody has been able to produce at this level before,’ said Professor Mohsen Assadi, who is leading the research. ‘We set a world record in hydrogen combustion in micro gas turbines. The ultimate goal is to produce electricity without harmful CO2 emissions. The innovation peaked in mid-May 2022 when an important milestone was reached: the team started running the turbine on 100% hydrogen. Now, researchers at the University of Stavanger have announced that they have successfully developed a process for using pure hydrogen as a fuel in a gas turbine, the institution published on May 31 in a press release. The whole bonding process takes only about five seconds – much faster than existing surgical glues.Gas turbines can be found everywhere, but as the world moves towards zero emissions, features will need to be adapt or left behind. The acid is then quickly able to form weak hydrogen bonds with those now-dry surfaces, sticking them together.Ĭhemicals called NHS esters, which are present within the polyacrylic acid, subsequently form much stronger covalent bonds with proteins in the tissue. Commonly used in diapers, it starts by absorbing bodily fluids on the two surfaces to which it is applied. On both sides of those strips is a material known as polyacrylic acid. The base of the tape takes the form of a strip of either gelatine or chitosan, both of which harmlessly break down within the body after the job is done – gelatine lasts for a few days, while chitosan can last anywhere from a month to a year. Those two surfaces are then pressed together, with the tape holding them that way until the healing process is complete.
The idea is that pieces of the tape get placed between two surfaces that need to be joined, such as the opposing sides of an incision made within an organ. Scientists at MIT have developed what could be a better way to go, in the form of a double-sided tape. Although surgical sutures are routinely used to close wounds within the body, they can actually damage fragile internal biological tissue, sometimes causing infections or other complications.
