The race to expand the use of biomethane as a vehicle fuel has left some doubtful as to whether we can always know exactly what fuel we or others are actually using.
There is a certain level of concern that it might be difficult to tell whether consumers are actually relying on proper biomethane or other, more dubious substances.
In 2015, Volkswagen issued an apology after it was found that it had installed technology in 11 million cars that produced inaccurate, inflated results on emissions tests.
Indeed, the automotive industry has less than a clean sheet when it comes to achieving emissions standards.
Other concerns about biomethane persist, but the idea that we can create a substantial amount of fuel by recycling waste is too attractive to ignore.

Indeed, there are many companies that are already using biomethane, in either its liquid or compressed form, to power their vehicles.
UK retailer John Lewis Partnership, for example, has already started some of its delivery trucks on biomethane and hopes to be fully reliant on the fuel to power its trucks by 2028.
Since the Russian invasion of Ukraine, alternative fuel supplies have become a hot topic. Many are keenly aware that governments are applying sanctions against Russia while continuing to rely on the country for supplies of natural gas.
Efforts to come up with an alternative to fossil fuels are nothing new, of course. But the renewed interest has an increased focus on biomethane, an alternative fuel that can be produced from decaying organic waste.

Regardless of whether the European Commission’s target is achievable, it seems likely that efforts to produce biomethane will be ramped up in the coming years.
Baldino fears that the rush to source enough material to feed the increasing number of anaerobic digesters will prompt the use of crops such as maize, which is much less environmentally-friendly.
One expert who is concerned about our ability to reach biomethane targets is Chelsea Baldino, a researcher at the International Council of Clean Transportation.
There's concern about how the materials will be transported to the digesters and how the gas will be purified once it is produced.
Anaerobic digesters, which are the machines that actually turn the festering material into fuel, can run on a wide range of materials.
The European Biogas Association, by contrast, believes that the 35 bcm target is definitely achievable even without the use of crops such as maize.
They can produce fuel from feedstocks, including sewage sludge, animal fat, seaweed, forestry waste, and grass cuttings, in addition to discarded household food and animal manure.
Furthermore, burning biomethane only releases carbon that was already in circulation, whereas burning natural gas releases carbon that would otherwise remain sequestered.
“So what are we waiting for?” we hear you ask. Indeed, it looks like we have much to gain and little to lose by ramping up biomethane production.
Biomethane arguably has the upper hand when it comes to harmful emissions, since capturing it from decaying matter prevents methane from being released into the atmosphere.
The second advantage to biomethane is that it is much more location-independent, i.e. governments do not have to rely on countries with fossil fuel reserves.
However, there are two important differences between biomethane and natural gas. The first difference is related to greenhouse gas emissions.
The aim is to replace around 150 billion cubic meters (bcm) of Russian gas with a combination of gas from other sources and other alternative energies.
It can also be sent via a grid to power household boilers. Indeed, half of Europe’s biomethane consumption in 2015 was for the purpose of home heating.
One option that has garnered a lot of attention and interest is biomethane, which can be produced from decaying organic matter, such as food waste.
The European Commission recently set ambitious new targets for the production of biomethane and other alternative fuels in Europe.
To quote Ursula von der Leyen, president of the Commission, "We must become independent from Russian oil, coal and gas. We simply cannot rely on a supplier who explicitly threatens us."
It works as follows: the waste organic matter releases biogas, which can be collected and purified to produce methane (or biomethane, as it is called in this context).
The Commission hopes to provide around 35 bcm of biomethane by 2030, which represents a more than 10-fold increase with respect to today’s output.
