Compressed natural gas (CNG)

Compressed natural gas (CNG) is a compressed form of the natural gas commonly used in homes for cooking and heating. Widely recognised as a reliable and clean fuel source, CNG has become a cheaper, cleaner and efficient fuel for road transport.

Major transport fleet operators are increasingly choosing CNG over diesel, petrol and even liquid petroleum gas (LPG).

ActewAGL is committed to the growth of CNG throughout the ACT region as an affordable, cleaner transport fuel option.

CNG makes sense

CNG makes sense because it:

  • is cheaper as it is not reliant on world oil prices
  • provides comparable vehicle range, and increased vehicle efficiency because it operates under higher pressure than petrol
  • is abundant in Australia, offering a secure energy source
  • has a proven track record
  • is one of the safest available because it is not toxic and is lighter than air so — unlike diesel, petrol or LPG — it will quickly dissipate if a leak should occur
  • is more environmentally friendly because it is cleaner burning than diesel or petrol, releasing less carbon emissions.

CNG for transport fleets

While individual operators can realise the benefits by using compressed natural gas (CNG), private and government fleets may also realise significant reductions in their vehicle operating costs. We know, because we're using CNG in our own fleet.

ActewAGL is committed to providing low cost compressed natural gas for your transport needs.

Fleet operators with restrictive fuel policies may face higher operational costs and expose their business to a higher carbon footprint. This is frequently compounded by purchasing popular makes, models and configurations of vans and trucks which are often big carbon emitters and can lead to higher ongoing operational expenses and environmental impacts.

Making the right fuel investment decision offers owners significant reductions and stability in fuel operating costs, resulting in better investment returns.

CNG vehicle choices

Factory fitted CNG vehicles are now available in Australia. Traditional conversion of existing or new vehicles is also available using the latest CNG technologies and authorised conversion specialists. Both options are cost effective and returns on the investment strengthens the case for CNG. When compared with conventional fuels, CNG represents good value to the fleet operator and owner.

CNG refuelling

  1. Start at the pay station. Swipe your fuel card, enter your vehicle kilometres and pump number. The tank will automatically start to fill. The auto pay will ask if you would like a receipt.
  2. Connect nozzle to vehicle CNG fuelling point and lock into position by turning the control valve — no gas will flow until this valve is locked. This is a quick connect fitting that makes a CNG fill-up both quick and safe.
  3. When the tank is full and the gas flow stops, turn the control valve to release latent pressure left in the hose. Disconnect nozzle and return to pump dock.
  4. To leave, drive up to the gate, which will automatically open.


For your safety, there is an emergency stop button located at the end of pump 3. In case of emergency at the refuelling station, follow the CNG emergency procedures.
