Hydrogen — ESSENTIAL TO LIFE: Hydrogen is super-abundant in the universe. It is essential to life. It is “renewable”, in the sense that it's virtually unlimited. It powers our sun, which converts hundreds of million tons of hydrogen into helium every second, which energises life on earth. The hydrogen in the sun's core will not run out in the next 5 to 6 billion years. And down here below, the drive towards “green hydrogen” has sparked immense enthusiasm, fuelled by the significant strides and momentum built at COP28, which reflects a shared commitment to creating a sustainable future.

STOCK Bio fuel / hydrogen — SWISS-ARMY KNIFE OF ENERGY: Hydrogen can theoretically be used for a variety of purposes. How abundant? Two hydrogen atoms are attached to one oxygen atom to make water. Both these elements make our planet habitable. Hydrogen can fuel trucks and aircraft, drive industrial processes, and light up cities with electricity, all while emitting only minimal traces of harmless vapour. Image Credit: Shutterstock

Hydrogen — GREEN ECONOMY: The global hydrogen market size is expected to reach $410.6 billion by 2030, a study by MarketsandMarkets. Numerous companies have pledged to significantly scale up their production of green hydrogen in the next decade. This involves utilizing solar or wind energy to fuel electrolysers, which in turn separate water into its elemental components—hydrogen and oxygen. The overarching expectation is that the continued momentum in renewable energy advancement will lead to a substantial increase in renewable energy availability and a notable reduction in the cost of power generated from green sources.

Electrolyser — HOW ELECTROLYSERS WORK: In a nutshell, all electrolysers works by passing an electric current through H2O — water — via electrodes. This current then divides the water into its elemental components, hydrogen and oxygen. This entire process consumes energy. Ideally, if the process were 100 per cent efficient, all the energy input would be dedicated solely to water splitting. Image Credit: Hysata | Australian Renewable Energy Agency

Electrolyser — EFFICIENCY GAINS THROUGH RESEARCH:Traditional electrolysers have, until now, generated considerable heat due to electrical resistance, similar to an electric heater at home. This heat is wasted energy; it also necessitates additional energy for cooling. Electrolysers typically require substantial cooling efforts — consuming even more energy. Therefore, reducing resistance not only increases the available energy for water splitting but also minimizes heat generation, subsequently lowering the demand for cooling.

Electrolyser — "95% EFFICIENT ELECTROLYSER”: Its potentially disruptive, world-leading 95 per cent efficiency has been recognised via publication in top-tier journal Nature Communications. It is also already ahead of IRENA’s 2050 electrolyser efficiency target. The Hysata engineers, including electrolyser industry veterans, have been designing and scaling up their novel electrolyser systems. Backed by leading global investors, Hysata is moving rapidly towards manufacturing at the multi-gigawatt scale needed to address climate change. Hysata is building their first commercial-scale hydrogen electrolyser in their new manufacturing facility in Port Kembla, New South Wales, Australia.

STOCK Bio fuel / hydrogen — LEVERAGING SURPLUS RENEWABLES: Leveraging surplus renewables, sourced from floating wind turbines or solar farms, is expected to bring down the cost of renewable-powered electrolysis below that of alternative methods for hydrogen production. This, in turn, is anticipated to facilitate a swift worldwide increase in the production of green hydrogen. Nevertheless, while industry analysts can discern a plausible route to enhanced hydrogen supply. Demand may not look rock solid by hydrogen has always been used in fertilisers and oil refineries.

In the oil industry, hydrogen is most commonly used in petroleum refining as well as fertiliser production. The clean-burning gas is forecast to play a central role in reducing the carbon footprint of heavy industries such as steel and chemicals. Currently, most hydrogen production requires the use of fossil fuels. This won’t be the case for long. Image Credit: AP

Adani Group — INDIA’S ROLE: India seeks to transition from being a net importer of fossil fuel, valued at Rs7 trillion ($84 billion) annually, to a green hydrogen net producer. One study shows the subcontinent would need around 38 GW of renewable energy (at an average capacity utilisation factor of 21 per cent at a total footprint of 1,824 km², or 0.06% of India’s total land area of 3.287 million km²) to meet demand for green hydrogen. This is estimated to curb a total of 42,000 tonnes of CO2 per year. Indian company Avaada is developing state-of-the-art electrolyser manufacturing capacity to cater to the increased global demand.

Hydrogen — MARKET: Currently, it is difficult to assess the most likely major applications of hydrogen, though prices are expected to go down with production ramp in many parts of the world. Currently, many firms which are considered as viable potential users of green hydrogen currently use very little or none of it. But given the hefty investments to retool power systems to run effectively off hydrogen, the “tipping point” may not be far off. Image Credit: DNV Transition Outlook
