There are several alternatives for generating electrical power, each with its own set of advantages and challenges.
Hydrogen (H₂) Power - the intelligent Solution
Hydrogen (H₂) Power Generation offers a scalable, sustainable solution for Australia’s transition away from coal. PEM (Proton Exchange Membrane) hydrogen generation, which can utilize seawater as its source, is a breakthrough given the vast availability of seawater, making hydrogen production both sustainable and scalable.
As we approach the summer of 2024-2025, temperatures in some regions—particularly the outer areas of cities—could soar to the high 40s or even 50°C. Running air conditioning over extended periods during these extreme conditions will place an enormous financial burden on both industries and private users. This highlights the urgent need for more affordable energy solutions.
Now, imagine harnessing the power of a material so extraordinary it feels like something straight out of science fiction—something that could rival Kryptonite in its potential to change the world, but for the greater good. That material is graphene. While it may not be green or glow like Superman’s fictional Kryptonite, graphene is no fantasy - it's reality.
Graphene is the strongest material known to man—far stronger than steel, more conductive than copper, and much thinner than a sheet of paper. At just one atom thick, graphene forms a lattice that is a game-changer in the energy world and has the potential to revolutionize many other industries. By leveraging accumulated know-how, graphene production methods can become more economical and scalable, making it financially sustainable for mass production.
This will not only transform industries such as energy and manufacturing, but also has the potential to revolutionize the computer industry, sensor technology in medical radiology, and assist countless other industries. Moreover, this transition will open doors to large-scale employment opportunities and bring significant economic benefits across sectors.
In fact, factories in Germany are already producing supercapacitors and super batteries using graphene technology - far outperforming Tesla batteries and virtually every other battery on the market in every aspect. These advancements push the boundaries of energy storage, efficiency, and sustainability, paving the way for a future where graphene revolutionizes the global economy.
ARE YOU THE INVESTOR'S? - THE TIME IS NOW
Hydrogen production could be radically enhanced by implementing graphene-assisted PEMs, boosting electrolysis efficiency, cutting down energy costs, and extending system lifespans. Additionally, using graphene to improve the efficiency of mechanical components, coils, and other parts would push energy systems into a realm of performance we’ve never seen before. By investing in advanced research and establishing graphene production facilities, we can bring this science-fiction-like material into real-world applications, turning theoretical potential into a practical, unstoppable force for Australia's energy revolution.
In this context, green hydrogen becomes even more critical. As Australia transitions to hydrogen power, hybrid hydrogen-natural gas turbines can be used as an interim solution until 100% hydrogen is available. These turbines can run on both fuels, ensuring energy stability during the transition. By adopting hydrogen, not only can we reduce CO₂ emissions, but we can also help lower energy costs for consumers, alleviating the rising cost of living caused by extreme weather and energy demands.
There’s no better alternative than green hydrogen, which can be produced locally from seawater and offers significant export opportunities. Australia must act now, following the lead of other nations already investing in this technology. Delaying these decisions will only increase the burden on consumers and leave the government responsible for climate inaction
