The objective of the GoI to regulate an affordable natural gas price through MEMR Regulation No. 8/2020 undoubtedly benefit the industrial sector. However, the regulation should be carefully implemented and monitored to prevent revenue loss in the natural gas business entities and avoid underperforming gas users/industries. The study finds three main issues in implementing the new regulated natural gas price. First, the compensation limit for the upstream natural gas entities is problematic for KKKS, whose annual loss is higher than the annual government take. Second, a detailed incentive mechanism for natural gas transmission and distribution companies is unavailable. And third, the evaluation scheme on the industry’s performance remains unclear.

The present paper presents the development effort and pre-commercial deployment of Explorer II — a semi-autonomous, self-powered, tetherless robotic platform, carrying a Remote Field Eddy Current (RFEC) sensor, for the inspection of unpiggable natural gas transmission and distribution pipelines in the 6 to 8 inch (152 to 203 mm) range, including those that feature multiple diameters, short radius and mitered bends, and tees. The system is based on a modular design that allows the system to be deployed in various configurations to carry out visual inspection and/or non-destructive evaluation (NDE) of a pipeline. The heart of this system is a RFEC sensor able to measure the pipeline’s wall thickness. In addition, two fisheye cameras at each end of the robot provide high quality visual inspection capabilities for locating joints, tee-offs, and other pipeline features. The system can operate, including launching and retrieval, in live pipelines with pressures up to 750 psig (50 bars). The system is currently being offered for pre-commercial deployments and is expected to be commercially available in the Fall of 2010.

Abstract In this research, we utilize Southern California (SoCal) natural gas transmission pipelines and underground storage resources for transporting and storing hydrogen gas for a 100% renewable energy penetration. The goal is to determine to what extent natural gas infrastructure can be used to deliver and store hydrogen to meet SoCal electric demand for a 100% renewable energy portfolio. Hydrogen is produced from solar power generation using electrolysis next to the gas transmission pipelines whenever it is available in quantities greater than the electricity demand. It was found that using four main transmission pipelines owned by Southern California Gas company (SoCalGas) to transport hydrogen from the point of production to the four underground storage fields to store and later generate electricity through fuel cells can transport and store hydrogen sufficient to meet 40% of the SoCal electricity demand. That is, without any investment in additional transmission and distribution infrastructure, and without any investment in energy storage, the idea of building solar farms in the desert and using only the gas system for storage and transmission and distribution leads to a 40% increase in renewable electricity for the state.

The paper focus on dynamic bayesian network (DBN) inference system and its application on the natural gas transmission and distribution network for the system fault diagnosis which is including time restriction (that is the earliest start time and the latest end time) for task. DBN is a graphic model which can describe the relationships between variable data, and used for reasoning. After we research the basic model of DBN, and the maximum depend algorithm is improved which which can increase the feasibility of natural gas transmission and distribution network system. we can see the new model is more accuracy than the traditional technical fault diagnosis clearly. Also, simulation result can verify the design of DBN is effectively and valuable.
