Biomethane for heavy goods transport: G3’s pricing strategy that guarantees savings compared to diesel
Fuel is one of the biggest operational costs in heavy goods transport, but the true competitiveness of a fleet is measured by the total cost of ownership, not just by the price paid at the pump. That is why G3 | Go Green Gas’s pricing strategy guarantees companies a total cost of ownership (TCO) – which includes fuel, the vehicle itself and maintenance – that is lower than that of an equivalent diesel solution.
1. Fixed price: protection against market volatility
Geopolitical conflicts, regulatory decisions and international fluctuations make fuel prices difficult to predict. It is precisely for this reason that G3 allows companies to contract natural gas/biomethane at a fixed price, protecting them from unexpected price rises throughout the contract period. Benefits: greater budgetary predictability, protection against market spikes and greater financial stability for operations.
2. Guaranteed TCO lower than diesel
With G3, the TCO per kilometer for a gas-powered vehicle is guaranteed to be lower than that of a diesel vehicle. According to Pordata, 99% of heavy-duty transport in Portugal still uses diesel, making it the economic benchmark for the sector. By guaranteeing a lower TCO, G3 ensures real savings compared with the most widely used solution on the market: up to 10% savings on the cost per kilometer. It is not about tracking the price of gas; it is about guaranteeing how much it costs to operate each vehicle, and how much is saved compared with diesel.
3. Tailor-made hybrid models
Every fleet has a different risk profile. That is why G3 offers different pricing options, combining a fixed price with a guaranteed TCO in hybrid models – for example, 50 per cent of the fleet at a fixed price and 50 per cent indexed to the model with a lower cost per kilometer than diesel. The result: a balance between predictability and savings, without compromising on either.
Pricing tailored to each operation
The number of vehicles, routes, fuel consumption and seasonality make each operation unique. G3 designs bespoke pricing models that adapt to the risk taken on, maximise predictability and boost competitiveness compared to diesel.
Guaranteed savings, not just a promise
At G3 | Go Green Gas, we turn the transition to gas, biomethane or natural gas, into a tangible economic advantage. Through flexible and transparent pricing models, tailored to the profile of each fleet, we guarantee greater cost predictability and measurable savings compared to diesel.
