Off-Grid LNG Power Supply Chain

Gas & Power Supply Technology for The Off-Grid Client

To bridge the gap between the traditional utility grid and the needs of today’s industry, Volco Power offers complete “End-to-End” off-grid power solutions and services. From the supply of natural gas and power generation units to comprehensive service contracts, Volco Power’s solutions cover every aspect of your power and delivery system needs.

At Volco Power, our goal is simple; to reduce operating costs for our customers by providing a cheaper and cleaner on-site power generation solution to that of diesel.

  

 

Containerized Gas & Power Solutions

The Volco Power “Virtual Pipeline” LNG to power solution provides customers with an alternate option that reduces operating costs and emissions over the traditional off-grid power supply from diesel.

For remote locations, temporary power and/or long-term power supply needs, the use of containerized LNG and Power units ensure lower CO2 emissions and more importantly a significant reduction in operating costs over diesel power.

Natural gas as fuel

Today’s energy production is mainly focused on fossil fuels. However, the limited supply of these fuels as well as conventional technologies’ negative impact on the environment and our climate have promoted a shift towards new energy policies. In favor of an improved global ecological balance, natural gas will replace other fossil fuels to produce clean energy.

LNG – Liquefied Natural Gas

As the name implies, it is traditional natural gas which has been cooled to the point of liquefaction. Liquefied natural gas is odourless, colourless, non-corrosive, and non-toxic. It is also denser than gaseous natural gas. In fact, liquefied natural gas takes up about 1/600th the space that the same amount of gaseous natural gas would take up. The considerable reduction in volume makes LNG much more efficient to transport and store than regular natural gas.

Power Container

Factory pre-integrated and customizable per site requirements, the Containerized Series generator sets can provide significantly shortened lead time for installation, and a lower cost of ownership via a flexible design. These complete power systems are engineered and optimized for diverse power applications, compliant with ISO 9001 standards and produced in ISO 14001-certified facilities.

The Containerized Series generator sets are designed for harsh weather and strict acoustical standards, utilizing a standard 40' high cube container equipped with an array of innovative features, allowing the system to operate reliably even in the hottest environments – validated at ambient temperatures of up to 50 degrees Celsius.

No matter what your power demands and challenges are, our Containerized generator sets will meet your needs and expectations through a selection of pre-configured models and options. Customized solutions are also available with a wide selection of fuel systems, circuit breakers, controllers, filtration and cooling packages

LNG ISO Container

ISO Containers are designed with highly engineered thermal insulation and a rugged, durable construction that ensures low-pressure, low-temperature liquid has a safe journey when traveling long distances for extended periods of time. With versatility in mind, LNG ISO Containers are  intermodal, optimized specifically for transporting Liquefied Natural Gas (LNG) worldwide by rail, sea, and road All containers comply with important codes and standards including ASME/DOT, RID, IMDG, ADR, ISO, and TPED.

Benefits of Containerized LNG:

  • No transfer of LNG from ship to storage
  • Handling of containers is standard practice in container ports
  • Uses existing infrastructure
  • Fully Ex-proof; no electric installation on the container

40’ ISO LNG Tank Container:

  • 33.4 m3 LNG at 82% filling rate
  • Up to 80 days unattended holding time
  • Dry quick couplings for liquid, vapor and safety valves with integrated break-away couplings
  • Pneumatic ESD valves for liquid and vapor
  • IMDG container for sea, rail and road transport
  • Class approved type C tank according to IGC code
  • Suitable for stacking 6 high in container stacks

Regasification Container

The regasification unit use ambient air to vaporize the LNG, known as Ambient Air Vaporizer’s (AAV). LNG AAVs are of similar design to nitrogen vaporisers and comprise of several banks of finned tube cells. LNG is pumped through these cells and as it is vaporised, the gas is discharged at a temperature approaching ambient air temperature. A simple schematic of AAVs is shown as follows:

Natural draft: relies on wind and natural convective currents to move air over the units. As warm air comes into contact with the AAV cells, the air cools and becomes dense, causing it to flow downwards to the bottom of the cells. This causes the warm ambient air from the surroundings to be drawn through the top of the cells.

Small Industrial Off-Grid Applications

Roof Top Solar & Battery Storage Power Solutions

To bridge the gap between the traditional utility grid and the needs of today’s industry, Volco Power offers complete “End-to-End” off-grid power solutions and services. From the supply of natural gas and power generation units (Solar, Battery Storage & Generators) to comprehensive service contracts, Volco Power’s solutions cover every aspect of your power and delivery system needs.

At Volco Power, our goal is simple; to reduce operating costs for our customers by providing a cheaper and cleaner on-site power generation solution to that of diesel.

The off-grid solutions utilize a solar Photo Voltaic (PV) system mounted on the roofs of industrial units and incorporates one or more DC bulk energy storage system collectively sized to provide sufficient energy for the required commercial operations of a small industrial complex

Separate energy storage will provide power for a common emergency water fire abatement sprinkler system.

It is possible to evaluate a bespoke roofing system to maximize the area of solar PV panels and provide a theft-proof PV array

The overall system can be configured to integrate distributed energy storage into a single storage ‘pool’, while Individual unit power consumption will be remotely monitored.

Every customer is different, and every project is unique. Volco Power specializes in bringing the right technologies together to configure custom solutions for a variety of applications, including:

  • Energy management: peak demand reduction, back-up, photo-voltaic (PV) self-consumption, power quality.
  • Transmission and distribution: capacity management, asset deferral, frequency regulation, harmonic suppression, voltage support, and power quality.
  • Microgrid applications: grid management, PV integration, and grid enhancement.
  • Thermal and renewable power generation: virtual spin (no emissions), ramp rate control, frequency regulation, time shifting, voltage support, curtailment avoidance.
