Highlights
Vitali Vidavski introduces his theory of deep-seated primordial hydrogen, which posits that hydrogen was preserved in the Earth's inner core from accretion and has since been continuously decomposing and emitting hydrogen. He contrasts this with the mainstream scientific concept of serpentinization, arguing that his model is supported by independent research and laboratory experiments simulating Earth's core conditions.
Vitali recounts his early exposure to natural hydrogen in 1985 through Dr. Vladimir Larin's seminars. His involvement became more direct in 2005 when he joined Larin's group to commercialize their concept. He details their early exploration efforts, including electromagnetic data acquisition, and his return to the field in 2020 to translate Larin's book, leading to his current partnership in Avalon PTY LTD, focusing on natural hydrogen projects worldwide.
Vitali discusses the nascent natural hydrogen industry, highlighting the difference between 'finds' and 'discoveries.' He cites the Mali example as an accidental find, where subsequent systematic drilling yielded no commercial success, contrasting it with the continuous flow from the original well, which his concept explains. He criticizes the mainstream focus on geochemical processes like serpentinization, arguing they cannot produce hydrogen in commercially viable quantities or sustain continuous flow due to material depletion over geological timeframes.
Vitali emphasizes that conventional oil and gas exploration techniques are ill-suited for natural hydrogen. He explains that hydrogen's volatility and chemical aggressiveness prevent it from forming pressurized deposits or 'traps' like hydrocarbons. Instead, hydrogen migrates through vertical 'chimneys' or conduits. He advocates for a dynamic flux model for resource evaluation, contrasting it with the static 'gas in place' model used in oil and gas, which he believes leads to unsuccessful drilling endeavors by many companies.
Vitali critiques the 'green hydrogen' model (electrolysis) due to its inherent energy inefficiency and reliance on subsidies, stemming from basic molecular physics. He asserts that natural hydrogen, being naturally occurring and continuously generated, is a superior, eternal, and carbon-neutral resource. He highlights that the goal is simply to capture naturally flowing hydrogen, acknowledging the subsurface risks but emphasizing that existing oil and gas drilling technologies can be adapted for extraction, though exploration requires a new mindset.
Vitali clarifies that natural hydrogen exploration does not involve searching for reservoirs but rather for anisotropic irregularities in the crust that act as conduits for hydrogen migration. He explains that these 'chimneys' can be modeled using specific seismic algorithms. For source identification, he relies on isotopic signatures (Delta D or Delta H) and helium isotope ratios (Helium-3 vs. Helium-4) to distinguish between deep-seated primordial hydrogen and crustal sources. He also mentions surface indicators like circular depressions as signs of active degassing.
He outlines a multi-stage exploration methodology, starting with soil surveys, gas chromatography, satellite imagery, and drone-based gas detection, followed by adapted geophysical techniques. He discusses technical challenges in drilling, such as operating in hard abrasive formations and low production pressures, and the potential for hydrogen embrittlement of equipment. He also notes the impact of associated gases, financial planning uncertainties, and the need for new development models, including 'harvesting' hydrogen from shallow wells.
Vitali touches upon the evolving regulatory frameworks, particularly in Australia, where natural hydrogen is gaining recognition under mining or petroleum legislation. He highlights the impact of over-regulation and the importance of private and public investments, urging for fair competition in R&D grants. He also addresses the academic resistance to alternative concepts like Larin's, attributing it to a comfort zone within mainstream science and a reluctance to challenge established dogmas.
He foresees the advancement of natural hydrogen exploration through streamlined and standardized processes, adapting technologies like multilateral drilling and specialized completion designs. He emphasizes the potential for natural hydrogen in autonomous, off-grid power generation. Vitali highlights the crucial role of interdisciplinary collaborations, citing examples from nuclear physics and astrophysics, which provide independent validation for their deep-seated primordial hydrogen concept, underscoring the need for a new approach to this unique commodity.
