In 2023 Pironon and de Donato announced the discovery of a deposit they estimated to be some 46 million to 260 million metric tons (several years worth of 2020s production). [18] In 2024, a natural deposit of helium and hydrogen was discovered in Rukwa, Tanzania., [19] as well in Bulqizë, Albania. [20]
Hydrogen isotope biogeochemistry (HIBGC) is the scientific study of biological, geological, and chemical processes in the environment using the distribution and relative abundance of hydrogen isotopes. Hydrogen has two stable isotopes, protium 1 H and deuterium 2 H, which vary in relative abundance on the order of hundreds of permil.
The model predicts the characteristics of hydrogen deposits based on where the gas has been found, in what quantities, and the rates at which natural processes are known to produce it.
Hydrogen gas and water have been found more than 6,000 metres (20,000 ft) deep in the upper crust in the Siljan Ring boreholes and the Kola Superdeep Borehole. Data from the western United States suggests that aquifers from near the surface may extend to depths of 10,000 metres (33,000 ft) to 20,000 metres (66,000 ft).
Microbial hydrogen production. Biohydrogen is H 2 that is produced biologically. [1] Interest is high in this technology because H 2 is a clean fuel and can be readily produced from certain kinds of biomass, [2] including biological waste. [3]
Nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago, as the basic or primordial ratio of 2 H to 1 H (≈26 atoms of deuterium per 10 6 hydrogen atoms) has its origin from that time. This is the ratio found in the gas giant planets, such as Jupiter.
The deposit is one of the world’s highest-grade deposits with more than 40% organic content and 66% conversion ratio into shale oil and gas. The oil shale is located in a single calcareous layer 2.5 to 3 metres (8.2 to 9.8 ft) in thickness and is buried at depths from 7 to 100 metres (23 to 328 ft). [ 6 ]
The world’s first hydrogen-powered commercial passenger ferry will start operating on San Francisco Bay as part of plans to phase out diesel-powered vessels and reduce planet-warming carbon ...
