... Abstract White hydrogen (H 2 ), naturally occurring within the Earth's crust, represents a promising yet underexplored opportunity in the transition to clean energy. The aim of this review is to synthesize the current state of knowledge on white H 2 , particularly its formation mechanisms...

... Summary This study evaluates the economic and environmental impacts of hydrogen blending ingas turbines using three years of operational data from a natural gas-powered plant. The objective is to understand how varying hydrogen blending ratios, from 5% to 100% by molar fraction, influence fuel...

... Abstract High-temperature electrolysis of steam is one of the most energy-efficient techniques for producing hydrogen. Coupling the process with conventional oil refining plant can help this industry lowers its carbon footprint by using the low-carbon hydrogen instead of hydrogen derived from...

..., methane, nitrogen, hydrogen) in an extra-heavy crude oil field in the Eastern Venezuela Basin, with special emphasis on the analyses of phase behavior, role of cushion and type of gas, flow and recovery mechanisms, as well as prospective additional recovery of hydrocarbons. To reproduce the phase...

.... In this article, we elucidate the similarities between petroleum engineering and subsurface engineering as they pertain to the energy transition. First, we list ongoing subsurface research initiatives related to the energy transition, which includes projects focused on CO 2 and hydrogen storage, geothermal...

... and economic growth is the crux of CCU's appeal. This work conducts a comparative analysis of CCU methods, dissecting those with hydrogen integration and those without. By examining respective challenges, and potential driver for Carbon Capture and Utilization (CCU) deployment, insights will be provided...

... Abstract In today's quest for energy optimization and reduction of carbon emissions, hydrogen has emerged as a promising solution for capturing and storing surplus energy. With the increasing production of renewable energy leading to negative energy prices, hydrogen plays a pivotal role...

... through three flashing units, each with progressively lower pressure, facilitating the release and capture of absorbed CO 2 . The solvent, now free of CO 2 , is recycled back to the absorber for further utilization. Levelized Cost of Hydrogen The levelized cost of hydrogen (LCOH) consists of two...

... Abstract The production of clean fuels in Venezuela is currently a great challenge, since the country has huge reserves of hydrocarbons (mainly highly viscous) where acid gases such as hydrogen sulfide (H 2 S) are generated due to high temperatures involved in the production process (e.g. after...

... Abstract Hydrogen liquification is one of the main steps for using hydrogen in obtaining carbon neutralization. This process consists of cooling hydrogen to approximately 20 K and converting ortho-hydrogen to para-hydrogen. This paper presents a study in which the authors simulate the Linde...
