Ngva natural gas a solution for a clean and decarbonized transport system costco gas station merced

Looking to the road transport, we are facing a very deep transformation of the mobility model. We are moving from a matchup between conventional fuels and engines to a more composite system. Cost of installing natural gas furnace in this system, electrification will integrate conventional engines and fuels will progressively include more and more energy carriers produced on renewable energy sources with a wide variety of biogenic and synthetic processes.

CO 2 tailpipe emissions (measured or calculated) have been implemented in the past to calculate fuel consumption from vehicles fed with conventional fossil liquid and gaseous fuels. Looking to the hybrid powertrains and to non-fossil fuels, CO 2 tailpipe emissions do not reflect anymore; neither the overall efficiency of these vehicles, nor their real impact on climate change.


In order to consider the new solutions, a new metric will be necessary to assess the effect from the use of advanced bio- and renewable fuels.

The heavy-duty transportation sector is expected to play an increasing role in a global economy where logistics will ask for a growing number of freight trade all across europe. Calculate the cost of gas for trip in parallel, public transport and coaches will have to complement more and more personnel mobility in city and inter-city trips to facilitate traffic and improve the fruition of urban areas.

At the same time, it is fundamental to consider the specific priorities of the sector, where fuel cost represents approximately 30% of the operating costs and most of the operators are composed by small and medium enterprises. Over the total cost of ownership (TCO) and the environmental performance, load capacity, vehicle range, reliability and durability of the technologies are fundamental parameters that have to be considered.

Looking to natural gas, the ratio of volumetric energy density (kj/l) between diesel and CNG (200 bar) is 4,5 while between diesel and LNG is 1,6. Gas cost calculator aaa this explains why CNG and LNG together cover both urban-suburban missions and long distance: LNG trucks on the market are able to ensure more than 1.600 km with torque and power characteristics equivalent to diesel.

CNG applications on HD applications are well known: many municipalities have implemented CNG buses in their urban fleets, several examples of refuse trucks are also in service and a growing number of goods delivery services are based on this technology. How to figure out fuel cost per mile today, we have approximately 16.000 CNG buses and 10.000 CNG trucks on our road, appreciated for their contribution to air quality and very frequently used for overnight operations due to the lower noise emissions compared to diesel.

Looking to the future tightening standards on pollutant emissions, diesel engines will have to further increase the complexity (and costs) of the gas aftertreatment systems. Under this perspective, the use of a clean gaseous fuel such as natural gas is a clear advantage: compared to diesel nox emissions are reduced from 30% to 60% according to the different operating conditions (see www.Projetequilibre.Fr). Average cost of gasoline in california the gaseous nature of the fuel ensures a very low generation of particles from combustion, only promoted by the consumption of lubricant oil, especially in the domain of the ultrafine particles.

When using renewable gas, CO 2 emissions reduction is measured on the so called well-to- wheel (wtw) basis: overall reduction on the wtw basis is between 80% and 95% according to the different production pathways. When using liquid manure, the overall reduction is even close to 182%, meaning that the use of such a kind of biomethane provide a negative overall balance (we capture and convert methane that should have released to the atmosphere).

Role of the gas infrastructure is fundamental: natural gas is the only energy source that at the same time can also be used as fuel, and the existing system is therefore of key importance to ensure the needed flexibility in integrating renewable gas and in storing huge amount of energy. Calculate cost of gas used for example when converting excess of renewable electricity through the so-called power-to-gas processes.

Progresses at engine and powertrain level will also see the progressive implementation of electrified solutions, and also to optimize the management of the energy at vehicle level. And the role of low carbon / advanced bio- and renewable fuels will be fundamental to support the decarbonization of the existing fleet circulating on our road.
