They discovered that electrodes covered with a molybdenum telluride catalyst showed an increase in the amount of hydrogen gas produced during the electrolysis when a specific pattern of high-current pulses was applied.&nbsp;<\/p>\n\n\n\n<p>By optimising the pulses of current through the acidic electrolyte, they could reduce the amount of energy needed to make a given amount of hydrogen by nearly 50%.<\/p>\n\n\n\n<p>Dr Alexey Ganin, of the University of Glasgow\u2019s School of Chemistry, directed the research team. Dr Ganin said: \u201cCurrently the UK meets about a third of its energy production needs through renewable sources, and in Scotland that figure is about 80%.<\/p>\n\n\n\n<p>\u201cExperts predict that we&amp;rsquo;ll soon reach a point where we\u2019ll be producing more renewable electricity than our consumption demands. However, as it currently stands the excess of generated energy must be used as it&amp;rsquo;s produced or else it goes to waste. It\u2019s vital that we develop a robust suite of methods to store the energy for later use.<\/p>\n\n\n\n<p>&#8220;Batteries are one way to do that, but hydrogen is a very promising alternative. Our research provides an important new insight into producing hydrogen from electrolysis more effectively and more economically, and we\u2019re keen to pursue this promising avenue of investigation.\u201d<\/p>\n\n\n\n<p>Since the level of catalytic enhancement is controlled by electric currents, recent advances in machine learning could be used to fine-tune the right sequence of applied currents to achieve the maximum output.&nbsp;<\/p>\n\n\n\n<p>The next stage for the team is the development of an artificial intelligence protocol to replace human input in the search for the most effective electronic structures use in similar catalytic processes.<\/p>\n\n\n\n<p>The paper, titled <em>The rapid electrochemical activation of MoTe2 for the hydrogen evolution reaction<\/em> is published in Nature Communications. The research was conducted at the University of Glasgow, the University of Kiel, the University of Lisbon, and the Hungarian Academy of Sciences and was supported by funding from the Engineering and Physical Sciences Research Council (ESPRC) and the Carnegie Trust.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new method of extracting hydrogen from water more efficiently could help underpin the capture of renewable energy in the form of sustainable fuel, scientists say.
