Advantages of MEGC: Ensuring Reliable and Continuous Gas Transport


Multiple-element gas containers (MEGC) enable gas transportation from point A to point B, where conventional infrastructure is unavailable or uneconomical. This ensures continuous gas supply even in the most challenging circumstances.

MEGC has emerged as a cutting-edge solution to address the challenges associated with gas transportation, including CNG, hydrogen, biogas, etc. MEGCs offer many advantages, combining safety, efficiency, and versatility to meet the demands of diverse sectors.

In this article, discover more about MEGC and its advantages in storing and transporting gas and CNG

What is a MEGC?

Ensuring an uninterrupted gas supply is crucial. If a gas pipeline needs repairs (cutting out a corroded section, for example), it’s essential to maintain the gas supply to households. 

The multi-element gas containers typically transport and distribute large amounts of gas under high pressure (200–300 bars). 

MEGC is constructed with multiple compartments and adheres to international specifications and regulations. This ensures compatibility with various transportation modes, including road, rail, and sea.

Mobile storage for virtual pipelines

Equipped with a semi-trailer, MEGC by Macel Plin offers dedicated mobile storage for virtual pipelines. This enables the transportation of gases to remote or temporary sites where traditional pipeline infrastructure is unavailable or impractical. With the flexibility of mobile storage, our MEGC empowers companies to reach new markets and expand gas distribution networks easily.

Virtual pipelines are a crucial link between natural gas suppliers and end customers, facilitating gas transportation through tankers. This system is a bridge, ensuring seamless gas delivery from the supplier to the final destination without traditional pipeline infrastructure.

Advantages of MEGC 

Flexibility and adaptability 

One of the main advantages of using MEGC is its flexibility and adaptability. These containers can serve as backup solutions in emergencies or temporary alternatives when the conventional gas supply is hindered. For example, during pipeline maintenance or infrastructure shortages.

Versatility in gas types

MEGCs can accommodate various gases, from CNG to biomethane, hydrogen, etc.

The modular design allows for customization based on the specific requirements of different gases, ensuring compatibility and safety during transportation. This versatility makes MEGCs a preferred choice for industries with diverse gas transport needs.

Safety and efficiency

Regular maintenance and inspections ensure the safety and efficiency of MEGC. The entire production process of MEGC is monitored by the relevant “Notified Body”, which monitors every segment of production and installed materials.

Mobile pressurized equipment has a Pi (π) marking. The Pi mark indicates compliance with EU transportable pressure equipment regulations, ensuring safety and quality standard adherence.

What are the different types of CNG cylinders?

Four distinct cylinder types are available for high-pressure vessels (HPV) to store CNG and hydrogen. Each is designed to meet specific durability, weight, and safety requirements.

  • Type 1 consists of steel cylinders. While sturdy, they tend to be heavier compared to newer alternatives.
  • Type 2 features steel cylinders reinforced with composite materials, offering an improved strength-to-weight ratio compared to Type 1.
  • Type 3 utilizes a composite cylinder with a metal liner, combining the lightweight advantage of composites with the added durability of metal. 
  • Type 4 employs a composite structure with a polymer liner, optimizing weight reduction while maintaining structural integrity and safety standards.

Type 4 composite cylinders achieve a weight reduction of approximately 70% compared to Type 1 and 2 steel cylinders and 25% to 35% compared to Type 3 aluminum liner-based cylinders.

These different types of CNG cylinders provide options for various applications, ensuring flexibility and efficiency in storing compressed natural gas.

What is the common use of CNG?

Compressed natural gas is primarily used as an alternative fuel for powering vehicles. However, its utility extends beyond transportation, with applications in power generation, water heating, and air conditioning systems. 

CNG is increasingly used in power generation, serving as a cleaner-burning fuel than coal or oil. It also contributes to efforts to transition towards more sustainable and environmentally friendly energy sources. 

MEGC is deployed to deliver CNG beyond the work location for pipeline repair. This prevents households from being left without gas during maintenance work. This ensures that consumers continue to receive a steady gas supply, even amidst infrastructure maintenance or repairs.
