Gaznet offers CNG, biogas and hydrogen containers, also a selection of transportation products, all in stock. Read about CNG, biogas and hydrogen containers here.

CNG and hydrogen containers solutions

Gaznet OÜ has been operating in the gas system applications market since 2005 and offers various CNG and hydrogen containers, also a selection of transportation products.

Gaznet is sales and service partner for Norwegian Multiple Element Gas Container (MEGC) producer Umoe Advanced Composites AS in Eastern Europe: Poland, Ukraine, Baltics and Balkan countries. The benefits of MEGC are lightness, robust class fiber technology, extremely high flow, safety and the amount of charge and discharge that no competitor can offer.

CNG containers are made in Norway by Umoe Advanced Composites AS, which is the leading global supplier of large type IV fiberglass pressure vessels and transportation modules for CNG, biogas and hydrogen. The UAC container lasts 3 times longer than the average steel container and needs to spend up to 10 times less money for testing.

CNG, biogas and hydrogen are fuels for today’s issue with CO2 production by human activities. Our knowledge and engineering abilities allow us to offer the best quality transport, storage, and refilling solutions for CNG, biogas and hydrogen.

Why choose our CNG and hydrogen containers?

CNG and hydrogen containers with great construction and intelligent material

Our CNG and hydrogen containers have a plastic liner, stainless steel end fittings and composite construction of high-strength fiberglass and epoxy resin. The use of CNG and hydrogen containers eliminates problems with corrosion, also guarantees the absence of galvanic corrosion. Composite materials utilized in the design of UAC pressure vessels offer non-corrosive properties, wide temperature tolerances, high-strength fatigue durability, enhanced safety, and long design life in harsh and hazardous environments. In addition, CNG and hydrogen containers offer up to 70% weight reduction, compared to steel cylinders. Composite materials are highly flexible and scalable to accommodate larger containment and transportation gas volumes.

High quality standards

Our CNG and hydrogen containers are approved in accordance with EN 12245 and far exceed the requirements of the standard. This is especially important when testing for defects, impact tests and fire tests. Following and approved for ADR regulations PED and TPED. RID regulation for railway applications.

Uncompromised quality CNG, biogas and hydrogen containers for a low price

Best price in the market, even comparable to steel cylinder containers. Low-cost type IV pressure vessels in lightweight, robust fiberglass composite significantly reduce lifecycle costs, while preserving quality, safety and the lifetime of our products. Non-corrosive properties of the material require a less frequent need for inspection, lower maintenance costs, and offer a price-competitive alternative to carbon fiber solutions.

Ultimate safety with best quality CNG products

Ultimate safety delivered by our UAC partner’s solutions is granted both by the material properties of fiberglass pressure vessels and by the structural design of our CNG, biogas and hydrogen transportation modules. We subject our products to stringent fire, fatigue, stress rupture, burst, impact and proof tests. Our pressure vessels demonstrate superior safety levels, challenging carbon fiber and steel alternatives. Our CNG, biogas and hydrogen containers safely handle all types of high-pressure gas combinations, exceeding industry safety standards.

Biogas and CNG

Biogas and CNG are both the same natural gas methane, CH4. Biogas origin is organic, it is produced in digesters and from cow manure, silo, bio waste or mix of all available organic leftovers. Biogas usually contains at least half of methane and the rest is a mix of different gases, mostly CO2, sulfur, and sometimes ammonium. After cleaning, biogas has the same quality as CNG and consists of at least 95% of methane.

Where is biogas used?

Biogas can be used in the same fields as CNG or natural gas, biomethane can be inserted to the grid, off grid biogas plants can use UMOE Advanced Composite container to deliver biomethane at pressure 250-300 bars into injection point where pressure is again lower down to certain pressure of the grid. Sometimes even compressed to specific pressure of the grid.

Biogas production has a great effort for the environment, methane removed from the environment is the biggest cause of ozone hole prevention. Burning this methane in catalytic converted engines has a positive influence on the environment according to many studies. Using biogas in public buses and taxi fleets is most common way of reducing the environmental harm of transportation.

CNG is safer to transport compared to other fuels!

According to ADR regulation safety is mandatory in any pressure equipment especially Transportable Pressure Equipment Directive (TPED). Our biogas, CNG and hydrogen containers have a safety factor of pressure 3,2-3,6 times of work pressure. All cylinders are equipped with Thermal Pressure Relief Devices (TPRD). ADR also defines usage of section during the transport, that all section valves must be closed to keep 5000L Water Volume (WV) limit in the transportable hydrogen container. Also, maintenance and inspection are for precautions done by professionals in the CNG field.

Stationary storages as buffers for filling stations, industrial storages obtain ADR rules as well only for Pressure Equipment Directive (PED), a special directive that regulates all pressure vessels with work pressure above 1 bar (1000Kpa). Our CNG and hydrogen containers follow the same rules.

Another positive side of CNG is its ignition point at 540°C, which is almost double the ignition point of petrol or diesel. So adding together the gaseous state of CNG and the high ignition point, you get one of the safest alternatives for vehicle fuel used worldwide in transportation. CNG and biogas are stored in vehicles at pressure 200 bars. Also equipped with TPRD and frequently inspected pressure, vessels are safer than petrol or diesel tanks which can start to leak out of scratch.

Existing petrol vehicle can be converted into a CNG vehicle

If you wish to convert your petrol vehicle into a CNG-based or dual-fuel vehicle, it is possible to do that in authorized shops. Converting a vehicle into a CNG vehicle involves installing a CNG cylinder plumbing, a CNG injection system and electronics.

The CNG cylinder is usually stored in the trunk of a car or in case of a truck in the back of the driver cabin or on the sides. When converting a vehicle into a CNG vehicle, you do have to keep in mind that a CNG cylinder could take up much space in the trunk. However with factory-built CNG vehicles there is no such problem, as the CNG cylinder and CNG system is built under the body of the vehicle, remaining invisible to the eye.

Conversion to CNG can be ordered from Gaznet website. You also can find all CNG cylinders versions and hydrogen containers available in stock.
