Three gases · one network
LNG first.
LPG and CNG alongside.
One tractor fleet, one depot network and one GasTwin™ platform for all three gases. Safety procedures are kept separate, because each gas behaves differently: cryogenic, pressure-liquefied, compressed.
LNGFlow™CORELNG — liquefied natural gas
Cryogenic ISO T75, regas skid at the plant; road, sea and rail; satellite tanks for large users.
↗
GasFlow™LPGLPG — liquefied petroleum gas
ISO T50 and bulk LPG stations at the plant on a fee-based operating model; cross-border ISO export by road.
↗
GasFlow™CNGCNG — compressed natural gas
200–250 bar tube trailers from mother station to customer station; trailer swap scheduled from telemetry, for plants without a pipeline.
↗Depot, chassis and cleaning infrastructure are also shared with chemical ISO tanks (ChemFlow™) and food-grade liquids (FoodFlow™) — not CF Energy’s commercial focus.
LNG transport · multimodal
One ISO tank,
three ways to travel.
The same ISO T75 travels by truck, ship and rail wagon, so cargo is never transferred en route. CF Energy picks road, sea or rail — or combines them — by distance, volume and how urgent each delivery is.
Road
Tractor units and dedicated chassis carry ISO T75s from terminal or depot to the factory gate within each hub’s service radius.
- Delivery and tank swap scheduled from telemetry
- Dangerous-goods trained drivers, journey monitoring
- Serves small and mid-size LNG users
Sea
ISO T75s loaded on container feeder vessels on the Cai Mep – Hai Phong route, extending to Da Nang and Vung Ang, under IMDG Class 2.1 dangerous-goods procedures.
- On-deck stowage, segregation, remote pressure monitoring
- Dozens of tanks per sailing, lowest cost per tonne
- Port handling at both ends by partners within the group ecosystem
North–South rail
ISO T75s on flat wagons along the North–South railway, a complementary and backup mode when weather or sailing schedules disrupt the sea route.
- Fixed timetable, independent of sea conditions
- Short road legs connect northern and southern depots
- Adds redundancy for long-term contracts
New direction · Marine LNG
From ISO tanks ashore
to the ship's fuel tank.
Vietnam has a green-energy transition programme for transport (Decision 876/QĐ-TTg, 2022) and is drafting an emissions-reduction roadmap for its fleet. With ISO T75 tanks, a port network and a data platform already in place, CF Energy takes LNG one leg further: from plant to quayside, metered.
Fishing vessels retrofitted to Diesel–LNG dual-fuel
High-power vessels on long trips, with fuel the biggest cost of every voyage. The workable route is to keep the diesel engine and add an LNG dual-fuel system — which needs LNG supply right at the fishing-port cluster.
- Bunkering by fishing-port cluster, no scattered investment
- ISO T75 as mobile buffer storage at port, truck-to-ship loading
- Per-trip fuel and emissions data for MRV records
Bay tour boats and coastal passenger vessels
Short routes, fixed schedules, back in port every night, operating in bays that need to stay clean — a natural fit for LNG: one bunkering point serves the whole fleet.
- Pier-side station with a satellite tank or ISO swapped on schedule
- Less smoke, odour and noise at the passenger pier
- Emissions certification for green tourism products
Coastal vessels and river–sea barges
North–South and river–sea routes have fixed end points, so LNG bunkering at both ends is enough. Works alongside Nam Duong's barge and river–sea fleet in the ecosystem.
- Loading at route end-ports, sharing ISO depots
- Safety files per maritime and class regulations
- Prepared for lower-emission fuels after LNG
LNG supply to portISO T75 from import terminal to fishing-port clusters, tour piers and coastal ports — by road, sea, rail.
BunkeringPier-side station or direct ISO/truck-to-ship loading; safety procedures, ESD, gas detection.
Survey & documentationVessel survey, tank space, ventilation, fire safety; coordination with class and retrofit technology partners.
MRV dataGasTwin™ logs diesel, LNG, engine hours and route per voyage — the figures needed for green credit and carbon credits.
ESCO modelThe owner leases the equipment and shares the fuel saving, instead of paying all the capital up front. CF Energy does not sell gas.
CF Energy is looking for pilot partners port cluster by port cluster. CF Energy covers supply, bunkering, engineering and data; on-board design and installation is done by technology partners and certified yards under registry rules.

Vietnam context · public sources
All three modes
already running in Vietnam.
Multimodal LNG in ISO tanks has already been done in Vietnam. The milestones below were announced by companies and the press; CF Energy builds on that infrastructure and precedent.

The Thi Vai LNG terminal starts shipping LNG in ISO tanks by truck to the South and South-Central regions — the road leg is commercially live.

Five steps,
each with a handover.
Each step states what data is needed, what must be decided and which documents are handed over before moving on — so neither side's engineers have to guess.

Next to the deep-water port; ISO depot and cleaning station for chemical and industrial-gas tanks.
Hai Phong
Northern end of the coastal route; receives tanks from ships and distributes to the North and Centre.

Why CF Energy is different.
Three things CF Energy has because it sits inside CF Group — with a question to test your current supplier.
Moat · Ports
The North–South ISO LNG route starts at the quay
Two ports, one handling operator — why it is hard to copy.
Moat · Data
Who holds the tank’s data
You do not need to own the tanks, only to have every tank report to one platform.
Positioning · Neutral
Why we do not sell gas
Not selling gas means CF Energy can carry for every cargo owner, even two competitors.
Frequently asked
Nine questions
we hear most.
The questions engineering and procurement teams ask most often.
How long can an LNG ISO tank stand at the plant before venting?
T75 tanks are vacuum-insulated, so boil-off is slow; reference holding times are measured in tens of days. In practice GasTwin™ tracks pressure and level to schedule the swap before the threshold, so the customer does not have to watch it.
What does a plant need to receive LNG by ISO tank?
A hard-standing for the tank and tractor access, a location for the regas skid, a tie-in to the existing gas system, and fire-safety documentation. CF Energy surveys the site and hands over a survey record before the configuration is fixed.
Does CF Energy sell LNG or industrial gas?
No. CF Energy only transports, leases equipment and operates it. The gas belongs to the cargo owner; CF Energy charges per tonne, per equipment-month or under an operating contract.
Why ISO tanks rather than conventional road tankers?
An ISO tank is an international standard unit: the same tank travels by road, sea and rail without transloading, loads onto feeder vessels and flat wagons, and can stand as temporary storage at the plant.
Has LNG been moved by rail in Vietnam before?
Yes. In September 2024 the first train carried 16 LNG ISO tanks south to north under a road–rail model, reported by the press and the railway operator. CF Energy treats rail as a complementary mode to the sea route.
Which rules govern LNG ISO tanks at sea?
The IMDG Code, dangerous goods Class 2.1: on-deck stowage, segregation, remote pressure monitoring and pre-loading declarations. Procedures are designed with port partners and the feeder line.
Are chemical and food-grade tanks ever shared?
Never. Chemicals and food-grade liquids use separate tanks, cleaning lines and yards; food-grade tanks are cleaned and certified to food standards before every loading.
Does CF Energy supply LNG to vessels?
Yes. CF Energy brings LNG by ISO T75 to fishing-port clusters, tour piers and coastal ports, organises bunkering, safety surveys and per-trip MRV data. Vessel retrofit design and installation are done by technology partners under class rules. CF Energy does not sell gas; see the marine LNG page (Vietnamese).
When is CNG the better choice over LNG?
CNG suits mid-size plants within a mother station’s radius and without a pipeline; equipment is simpler, with no regasification. LNG suits large demand or long distance because one ISO T75 carries many times the energy of a tube trailer. CF Energy advises on actual volume and location.
