This innovative international project is aimed at developing a seasonal, high-volume transformation and storage solution for erratic renewable generation. Energy will be stored safely in gaseous form in underground facilities at depths of over 1,m. The research will focus on devising solutions to one of the biggest challenges facing the energy system of tomorrow: how to expand fluctuating generation of renewables such as wind and solar power while at the same time maintaining high levels of security of supply, especially in winter, when the possibility of generating power is low and demand is high?

The Final Rule follows the approach taken in the IFR by incorporating the provisions in two industry safety standards for UNGS facilities by reference but eliminates the requirement to treat the permissive elements of those standards as mandatory. The Final Rule also makes other changes to the IFR, many of which respond to issues raised in public comments, a petition for reconsideration filed by several industry trade organizations, and a petition for judicial review filed by the State of Texas in the U.

Court of Appeals for the 5 th Circuit. Additional information about the Final Rule, which takes effect on March 13, , is provided below. Numerous commenters challenged the appropriateness of the should-to-shall conversion, and PHMSA eliminated that provision in the Final Rule. The Final Rule prescribes the specific elements for that framework, which must include:. Operators of depleted hydrocarbon or aquifer reservoirs constructed on or before July 18, , must meet these enhanced IM requirements by March 13, Operators must complete baseline risk assessments of UNGS assets according to the following schedule.

In this case, the operator must promptly respond to the emergency, notify the Agency as soon as practicable, and document the emergency and any reason for the delay in notification. However, the Final Rule exempts operators from reporting safety-related conditions where a wellhead is isolated and the reservoir or cavern and all other components continue to operate normally without a pressure reduction.

The Final Rule affirms the well-established principle that states may impose additional requirements on intrastate facilities so long as the state has a certification with PHMSA and the additional requirements do not conflict with the federal safety standards. The IFR required operators to include procedures for operations, maintenance, and emergency response and management for UNGS facilities in the operations and maintenance manuals required for natural gas pipelines 49 C.

The Final Rule simplifies the procedural obligation by not requiring operators to include UNGS procedures in the gas pipeline manuals. The deadline to develop these procedures for existing facilities remains July 18, An UNGS operator must maintain records necessary to implement the procedures and review them every 15 months, but at least once every calendar year.

The Final Rule prescribes the specific elements for that framework, which must include: A general discussion or definition of risk management; Data collection and integration; Threat and hazard identification and analysis; Risk assessment; Preventive and mitigative measures; Periodic review and reassessment; and Recordkeeping. It must include: A plan for developing and implementing each program element; An outline of the procedures to be developed; Roles and responsibilities of UNGS facility staff assigned to develop and implement the procedures; A plan for training staff about the procedures and how they will be applied; Timelines for implementing each program element, including risk analyses and baseline risk assessments; and A plan for incorporating information gained from experience into the IM plan on a continuous basis.

Operations and Maintenance Procedural Requirements The IFR required operators to include procedures for operations, maintenance, and emergency response and management for UNGS facilities in the operations and maintenance manuals required for natural gas pipelines 49 C.

Londe, L.. Underground hydrocarbon storage is a mature technology, born in the early 20th century and very widespread today. The success of this technology lies in its economic efficiency, its safety and, ultimately, its excellent environmental track record. The market is divided among three techniques: 1 storage in porous media, by far the most widespread technique for storing natural gas; 2 storage in salt caverns, a technique that is suitable for all hydrocarbons; and 3 storage in mined caverns, a technique that is used for liquid or liquefied products. The market is currently changing. Underground storage facilities are under increasing stress from operators that are seeking to obtain the most from them.

In Minnesota, there are about 13, regulated underground storage tanks USTs in use. The Underground Storage Tank Program helps to prevent contamination caused by leaking tanks by focusing on technical assistance and compliance. The rules were most recently amended in to conform with the revisions to CFR 40, pt.

Due to the increasing demand for gas consumption during cold seasons, it is a sense of urgency to provide a reliable resource for gas supply during these periods. The objectives of this comprehensive research entail reservoir core analysis, reservoir fluid study, investigation and optimization of improved condensate recovery during gas storage processes in one of Iranian-depleted fractured gas condensate reservoir. We have attempted to make a balance among reservoir petrophysical and operational characteristics such as production rate, ultimate reservoir pressure after production, cumulative condensate production, number of wells and the required time periods for the reservoir depletion, to obtain an optimum condition for the gas storage process.
