Green hydrogen in the country: they warn about the use of water – Informed, upon return

Gabriel Correa Perelmuter, mechanical engineer and energy doctor, researcher at Conicet, warned about the inputs that will be used in the plant that will be installed in Río Negro to produce green hydrogen, and warned about the use of water in this process.

Argentina will receive an investment of US $ 8,400 million through the Australian company Fortescue to produce green hydrogen, as officially reported this Monday in the Scottish city of Glasgow, where the COP26 climate change summit takes place..

“Hydrogen is the most abundant chemical element that we have in nature, the problem is that hydrogen is not alone, we do not have it available by itself, therefore, we need some process to produce it,” Correa Perelmuter told Chain 3.

And he continued: “These processes have different forms and green hydrogen is produced through the electrolysis of water. This procedure produces the separation of the molecule into oxygen on one side and hydrogen on the other ”.

“That electrical energy necessary for the electrochemical reaction could be obtained from renewable sources, this is a process without emission of greenhouse gases that is called green”he explained.

Hydrogen can replace fossil fuels and is also transported through a fuel cell.

“Argentina has the availability of a renewable resource such as wind energy in Patagonia and solar energy in the north that make it unique. This makes hydrogen production more economical “said the specialist on the choice of our country.

And he added: “What will be installed in Río Negro is the hydrogen production plant, which is where these large electrizers are that are going to consume wind energy, surely there will be a wind farm for the generation of electricity that will then be the input for the electrolyzer or the various electrizers ”.

“On the other hand, you need water, it was suggested that it is seawater and a desalination process will be carried out, you have to know where the water is going to come from”, he warned.

“It is hydrogen to export and water is going to be exported and it is important to think about the energy transition to have a more sustainable world, but also that Argentina can make that transition in the short term and have technological sovereignty so as not to buy turnkey these plants, if not to be able to develop them in our country ”, he closed.
