The Origin and Occurrence of Natural Hydrogen

, 2023
Hydrogen is an attractive, clean, sustainable energy source primarily produced via industry. At present, most reviews on hydrogen mainly focus on the preparation and storage of hydrogen, while the development and utilization of natural hydrogen will ...

First assessment of hydrogen/brine/Saudi basalt wettability: implications for hydrogen geological storage

Frontiers in Earth Science, 2023
Introduction: Underground hydrogen (H2) storage is a prominent technique to enable a large-scale H2-based economy as part of the global energy mix for net-zero carbon emission.

Hydrogen storage in depleted gas fields: capacity and performance [PDF]

, 2022
The Paris Agreement to limit anthropogenic warming to 1.5 °C above pre-industrial levels requires rapid reduction of greenhouse gas emissions. The UK has a large natural gas demand which varies massively across the year, with peaks in winter up to ...

Prospects for exploration of hydrogen fields in riftogene structures of platforms (the case of the Dnieper-Donets Aulacogene)

Геофизический журнал, 2021
This paper shows the prospect to find industrial-scale hydrogen accumulations in riftogenic structures of platforms using the example of the Dnieper-Donets Aulacogene, located in the southern part of the East European Platform. Within the Dnieper-Donets

Unraveling G‐Quadruplex and i‐Motif Coexistence Within a Double‐Stranded DNA

Angewandte Chemie, EarlyView.
The relative thermodynamic profiles of G‐quadruplex (G4), i‐Motif (iM), and the duplex counterpart tune the simultaneous G4 and iM formation within a double‐stranded (ds) DNA. ABSTRACT DNA can transiently fold into variable arrangements, which are expected to exploit regulatory functions. Guanine‐rich sequences can fold into G‐quadruplexes (G4s), while

Toward a Fundamental Understanding of Geological Hydrogen Storage

Industrial & Engineering Chemistry Research, 2022
Geological H2 storage plays a central role to enable the successful transition to the renewable H2 economy and achieve net-zero emission in the atmosphere. Depleted oil and gas reservoirs are already explored with extensive reservoir and operational data. However, residual hydrocarbons can mix with injected H2 in the reservoirs.

Sustainable Pd‐Catalyzed Aminations “on Dirty Water”

Angewandte Chemie, EarlyView.
Aminations, done safely yet neat, and therefore, quickly, using low levels of Pd, in “dirty water” that must contain 30% KOH; not NaOH, and not at 5%,10%, 20%, 40%, or 50% KOH. Moreover, no base sensitivity of functional groups! Very cool. Thank you, Nature.

Methodological basis of mapping signs of industrial helium concentrations in Ukraine (Dnipro-Donetsk depression)

Мінеральні ресурси України
Helium is one of the most valuable industrial gases that is not widely distributed in the atmosphere and in the Earth’s crust. The unique physicochemical properties of helium make it indispensable in a wide range of industrial and research areas.
