Hydrogen Fuel

What is biogenic hydrogen fuel and is it fully renewable?

Jan 31 2024

Let’s explore the feasibility of utilizing underground hydrogen as a renewable energy source. The discovery of natural hydrogen deposits in north-east France by scientists at the University of Lorraine has opened up new avenues for sustainable energy research. These deposits, formed through the interaction of groundwater with iron-rich minerals, suggest a potentially self-renewing source of hydrogen. This study investigates the mechanisms behind this formation and evaluates the sustainability and practicality of harnessing such hydrogen deposits for future energy needs. 

The quest for renewable energy sources has become increasingly crucial in the context of climate change and depleting fossil fuels. Hydrogen, known for its high energy yield and clean combustion, is a promising candidate. Traditionally, hydrogen production relies on methods such as steam methane reforming and electrolysis, which have limitations in terms of sustainability and environmental impact. The recent discovery by researchers at the University of Lorraine of natural hydrogen deposits more than 1,000 meters underground offers an intriguing alternative. 

The underground hydrogen in north-east France is believed to be generated through a natural process where groundwater reacts with iron-rich minerals. This reaction splits water molecules (H2O) into hydrogen (H2) and oxygen (O2), potentially creating a continuous source of hydrogen. The key question is whether this process can sustain itself indefinitely. 

For hydrogen to be considered a renewable resource, its formation must occur continuously without depleting the involved elements. The sustainability of underground hydrogen hinges on several factors: the speed at which hydrogen is produced naturally must be sufficient to meet demand; the iron-rich minerals and groundwater must be replenished at a rate that sustains the reaction; and the extraction process should not cause significant ecological disturbance. 

Several challenges need to be addressed to harness underground hydrogen effectively. Current hydrogen extraction methods may not be suitable for deep underground reserves. The cost of extraction and purification must be competitive with other hydrogen production methods. Such hydrogen deposits may not be globally distributed, limiting accessibility. If the sustainability of underground hydrogen can be established, it could significantly impact the global energy landscape. As a clean and potentially inexhaustible energy source, it could reduce reliance on fossil fuels and aid in achieving carbon neutrality goals. Moreover, it could revolutionize the hydrogen economy by providing a more environmentally friendly production method. 

The discovery of natural hydrogen deposits presents an exciting opportunity in renewable energy research. While the prospect of an almost indefinitely renewing hydrogen source is promising, further studies are needed to understand the dynamics of its formation, sustainability, and practical extraction methods. If these challenges can be overcome, underground hydrogen could become a pivotal player in the future energy mix, contributing to a more sustainable and cleaner energy future.
