Energy transition
This paper reviews the simultaneous supercritical CO2/brine aquifer injection and water-alternating-gas methods for geologic carbon sequestration and proposes a novel integration with saltwater-disposal wells.
The objective of this study is to numerically investigate system behavior when storing H2/natural gas (CH4) mixtures in aquifer-related underground gas storage, and the effect of gas composition and salinity on energy-recovery efficiency.
In the past year, publications on CO2, natural gas, and hydrogen storage have increasingly focused on the design, evaluation, and optimization of storage plans. These efforts encompass a broad spectrum of challenges and innovations, including the expansion of storage reservoirs from depleted gas fields and saline aquifers to stratified carbonate formations and heavy-o…

This paper presents a summary of the results of a study of the potential for repurposing legacy oil and gas facilities in the Gulf of Mexico for uses in a blue economy. -
The authors of this paper describe a holistic approach toward integrating alternative fuels and novel prime movers into life-cycle performance of offshore vessels.

The Russian/Ukrainian conflict has shown that a division between energy-transition rhetoric and reality can lead to profound global consequences by creating an imbalance in nations’ access to diverse flows of energy. The Energy Basket composition is determined by the demands and fluidity of the grid, as opposed to high-minded rhetoric.

Shell’s venture capital subsidiary has acquired Sprng Energy, one of India’s largest renewables platforms, thus tripling its operating wind and solar power assets.

Many hurdles for marinization of green hydrogen production already have been overcome in the offshore oil and wind sectors. A fresh set of challenges, however, will rise around developing and deploying hydrogen production facilities offshore.

The partnership of Subsea 7 and Flasc has a plan to use out-of-service pipelines as pressure vessels in a hydro-pneumatic energy storage concept.

The assumption of lower emissions from natural gas only holds true when the methane leaks and flaring are addressed. Mitigation of methane emissions offers an opportunity for the oil and gas industry to drastically reduce overall emissions that are typically reported on a CO2-equivalent basis. Some producers opt to showcase their good performance via voluntary certifi…

Partnerships flourish in offshore wind, while Equinor expands its renewables drive and solar companies in the US come together to shore up the supply chain ahead of increased demand.

Using CO2 as the geothermal power fluid to generate electricity from low-temperature abandoned hydrocarbon wells can help reduce well costs and optimize energy production. In this paper, a previously developed coupled well/reservoir model is extended to study the effects of fluid properties on thermal output.
