Net-Zero reshapes energy and economic futures, driving rising natural resource demands. Underground saline aquifers, a globally overlooked resource, serve as natural CO₂ absorbers, energy storage vessels, and liquid mineral sources (lithium, deuterium, etc. for new energy and nuclear fusion). Single-purpose use (carbon reduction, energy storage or mining) is costly; circular multi-value development is vital for resource optimization and sustainable models. This paper demonstrated a triple-synergy solution after a decade of research, and analyzed the data from lab and pilots. The feasibility of the solution was validated through molecular simulations, laboratory experiments, and field analysis. Using unstable wind and solar power to inject gases into underground saline aquifers for the consumption of wind and solar power. Injecting industrial gas/air into saline aquifers yields three benefits. Injecting industrial waste gas or air primarily containing CO2 and N2 into underground saline aquifers yields three benefits. Scenario 1, Underground Carbon Capture: Saline aquifers' mineralization replaces ground-based CCUS, cutting costs by 90% for low-cost net zero. Scenario 2, Underground Energy Storage: As sealed geological structures, aquifers store compressed N₂ via differential pressure power generation, enabling long-duration storage for intermittent renewables. Scenario 3, Liquid Mining: Rich in new energy/nuclear fusion minerals such as lithium, beryllium, boron, potassium, uranium, and deuterium, aquifers enable extraction via gas injection, forming industrial value chains. This innovation disrupts traditional ground-based carbon capture, tank storage, and solid mining, integrating with wind/solar and nuclear fusion. The solution has achieved annual Mt-scale CO₂ storage, TWh power generation, and liquid mineral production in oilfields. With global aquifer distribution, it promises rapid replication to circular economy and climate sustainability.
Flexible operation of nuclear power plants provides a crucial opportunity to ensure the reliability of the intermittent renewable energy such as solar and wind energies in the electrical grid. Historically, nuclear reactors are well known for their primarily operation in the baseload generation due to their reliable and predictable energy outputs. However, advancement in nuclear reactors designs and control technologies enabled modern nuclear reactors to play the role of performing load following operation, where adjusting the energy outputs regarding the fluctuation in the renewable energy production and the electricity demand. In this role, nuclear plants provide residual-load following that complements the diurnal and seasonal profiles of solar and wind, reducing curtailment and maintaining system reliability.
This paper discovers the operational and technical feasibility of flexible nuclear reactor operations, emphasizing their capacity to critical grid services containing voltage stability, reactive power support, and frequency regulation. The new technologies and designs, notably Small Modular Reactors (SMRs) and advanced generation III+ reactors, show how nuclear power plant can effectively integrated to the electricity grid in order to enhance the performance of renewables.
Additionally, this paper illustrate the economic analysis comparing fixable nuclear operation against alternative grid stabilization method highlight the potential cost-benefit advantages, underscoring economic competitiveness and regulatory considerations critical for wider industry adoption.
Moreover, this paper discuss real world case study from countries actively performing nuclear flexibility such as France and Germany, which include evidence of practical outcomes, challenges, and solution advancement.
Conclusively, this paper demonstrate the strategic value and technical feasibility of flexible nuclear operation, presenting a solid, economically attractive pathway toward stable, sustainable and reliable energy system in the manner of rising renewable demand.

Greenhouse Gas (GHG) emissions monitoring, during field operations, is of crucial importance to oil and gas producers. The objective of this study is to introduce and evaluate the performance of a solar-powered GHG emissions monitoring system which can monitor, measure, track, and analyze GHG continuously, particularly Methane, Carbon Dioxide, and other required gases in real-time or near real-time to achieve several goals including compliance with regulations, emission reduction, environmental protection, reporting, operational efficiency, and early detection.
The GHG emissions monitoring system has several sensors that use several technologies to obtain the most accurate readings. For the measurement of methane emissions, the system uses gas standalone sensor pods which measure the methane and process the data into graphs using a Micro-Electro-Mechanical System (MEMS); while for measuring Carbon Dioxide emissions, a non-dispersive infrared sensor (NDIR) is used. The solar system is used to power the batteries without any need for electricity for one week. The system provides a Wi-Fi 868 MHz system to connect all the sensor pods together.
Monitoring of fugitive greenhouse gas (GHG) emissions typically involves identifying, quantifying, and tracking the release of GHGs from various sources that are not directly emitted through controlled processes. Emissions usually come from leaks, accidental releases, or inefficiencies in the handling of gases during production, transportation, or use. The study showed that using continuous emission monitoring helped to confirm the gas production system's reliability and conformance. Another key metric in measuring the system performance is Leak Detection and Repair (LDAR) which significantly enhanced the gas production system performance through early detection of leaks which allows immediate remedy for such leaks not allowing them to deteriorate. Using solar energy power supply reduced the need for power supply and manpower at the well site. Overall, this system increased the measurement accuracy by 15%-20% and reduced the measurement cost by 25%. The system offers optional remote monitoring & data download on-site and is characterized by the simplicity of deployment and flexibility of data collection either through the internet or on-site.
This study introduces a simplified yet efficient wireless solar-powered GHG emission monitoring system able to measure more than one gas simultaneously using different gas sensor technologies.

Net-Zero reshapes energy and economic futures, driving rising natural resource demands. Underground saline aquifers, a globally overlooked resource, serve as natural CO₂ absorbers, energy storage vessels, and liquid mineral sources (lithium, deuterium, etc. for new energy and nuclear fusion). Single-purpose use (carbon reduction, energy storage or mining) is costly; circular multi-value development is vital for resource optimization and sustainable models. This paper demonstrated a triple-synergy solution after a decade of research, and analyzed the data from lab and pilots. The feasibility of the solution was validated through molecular simulations, laboratory experiments, and field analysis. Using unstable wind and solar power to inject gases into underground saline aquifers for the consumption of wind and solar power. Injecting industrial gas/air into saline aquifers yields three benefits. Injecting industrial waste gas or air primarily containing CO2 and N2 into underground saline aquifers yields three benefits. Scenario 1, Underground Carbon Capture: Saline aquifers' mineralization replaces ground-based CCUS, cutting costs by 90% for low-cost net zero. Scenario 2, Underground Energy Storage: As sealed geological structures, aquifers store compressed N₂ via differential pressure power generation, enabling long-duration storage for intermittent renewables. Scenario 3, Liquid Mining: Rich in new energy/nuclear fusion minerals such as lithium, beryllium, boron, potassium, uranium, and deuterium, aquifers enable extraction via gas injection, forming industrial value chains. This innovation disrupts traditional ground-based carbon capture, tank storage, and solid mining, integrating with wind/solar and nuclear fusion. The solution has achieved annual Mt-scale CO₂ storage, TWh power generation, and liquid mineral production in oilfields. With global aquifer distribution, it promises rapid replication to circular economy and climate sustainability.
