Green hydrogen is one of the alternatives attracting the most significant interest and investment in the effort to wean the world off fossil fuels. However, its manufacturing efficiency remains low. It has now been raised to virtually the theoretical maximum through a method.
Hysata's technology for green hydrogen electrolyzers has reached a significant milestone that enables the electrolysis process to be more efficient. A work that has been reviewed by peers and published in the scientific journal Nature Communications.
The research shows that Hysata's capillary cell can make green hydrogen from water at a 98 % energy efficiency rate, exceeding the International Renewable Energy Agency's (IRENA) goal for 2050 and outperforming other electrolyzer technologies.
Because of the Ukraine conflict and high energy prices for fossil fuels like gas, this technology has artificially matched gray hydrogen costs. It allows hydrogen to be made from renewable sources to lower its costs, which are now artificially the same as gray hydrogen because of these factors.
Hysata's innovative method enables production at the cost of roughly 1.5 dollars per kilogram. Experts think a number could be the point at which this energy source becomes more common and, more importantly, a magnet for new money that helps the economy of scale grow.
And is that, despite the growing consensus that its usage in applications like road transport has limited economic viability, green hydrogen can be critical for decarbonizing intensive industries such as steel, heavy transportation, and the manufacture of chemical goods such as fertilizers.
A need that will continue to develop is anticipated that between 500 and 800 million tons will be used annually by 2050 to fulfill demand in these areas, resulting in the creation of a new multibillion-dollar industry.
Naturally, a massive increase in renewable energy sources will be required to enable this output. For example, and as an illustration, the amount of energy necessary to make one kilogram of hydrogen.
A fact that is not often reported but has been indicated in the instance of Hysata. According to the Australian business, it will take 41.4 kWh of power to manufacture one kilogram of green hydrogen using their revolutionary technique. Some modern electrolyzer systems use 47.5 kWh to achieve a 75% efficiency rate.
This will undoubtedly result in lower operational costs and capital requirements for hydrogen production. However, as we can see, a significant quantity of energy will be required for its manufacture, forcing us to redouble our efforts to install renewables to minimize reliance on fossil fuels.
This procedure significantly improves the efficiency of green hydrogen generation, increasing it to 98 %.
