Gold hydrogen is a naturally occurring form of hydrogen which is extracted directly from underground sources rather than industrial methods. It is formed as a result of natural geological processes and opens doors to a more sustainable solution for energy requirements. This could reduce the reliance on fossil fuels by a significant amount and can be used in clean energy generation, transportation fuel, industrial processes, and eventually decarbonising the gas grid.
The formation of gold hydrogen requires the interaction of water with mineral-rich rocks. This is facilitated through high temperature and pressure; however, it can also be affected by radioactivity which can ease the splitting of water molecules into hydrogen. The process begins with identifying hydrogen-rich formations. Here, they use precision drilling techniques to access the hydrogen gas which has accumulated in porous rocks resulting in concentrated subsurface deposits. The drilling process is similar to that of the gas and oil industry but less complex due to lower pressure and volatility. Aside from this, it does not require hydraulic fracturing which is a process whereby a fracking fluid (which consists of water, additives, and proppants) is injected into a well at high pressure and extracts natural gas or oil from underground rock formations. This process has dire effects on the surrounding environment, namely, water contamination, habitat loss, ecological impacts and the release of air pollutants and greenhouse gases. Once captured and collected, it goes through a purification process to remove any impurities or gases that were present in the deposit.
There are numerous benefits that arise with gold hydrogen. It does not emit carbon dioxide which significantly reduces greenhouse gas emissions. As a form of clean energy, it can diversify energy supplies and decrease the dependence on imported fuels which can increase levels of national energy security. This not only stimulates economic activities but also creates employment opportunities. As technology and extraction methods improve, gold hydrogen can be extracted at lower costs than other forms of hydrogen which also makes it cost-effective. Furthermore, infrastructure can be repurposed as the process is similar to the ones used for oil and gas and can accelerate production.
Although it seems like a very promising discovery, there are limitations that should be considered. The drilling process itself can still disturb ecosystems and release methane and other gases which could negate the other environmental benefits. Additionally, although a good number of deposits have been identified, the feasibility of extraction and efficiency of global distribution remain uncertain. Finally, there could be consequences that we cannot predict. Inadvertently, we could discover new fossil fuel deposits during extraction and if not handled carefully, this could lead to an increase of carbon emissions, rather than a decrease. Therefore, while the potential of gold hydrogen is indeed promising, it is important to consider possible drawbacks.
