CNG stands for Compressed Natural Gas. Natural Gas principally contains Methane along with presence of other heavier Hydrocarbons like Ethane, Propane, Butane, Hexane etc. When Natural Gas is compressed, it is called CNG.

Fossil Fuel is a complex compound of Hydrocarbons usually extracted from the crest of earth in form of Liquid or Gaseous compounds. These hydrocarbons are produced from the biomass and algae that was buried in the earth millions of years ago and got fossilised. The organic matter got decomposed by the bacteria and hydrocarbons were released. These, when extracted from the deep wells, form an important source of fuels today.

Yes. As explained earlier, CNG is Natural Gas in compressed state and Natural Gas is extracted from sources like Crude Oil wells, Shale Oil or Gas fracking wells or Cola Bed termed as Coal Bed Methane – CBM). All these sources are fossil sources making CNG a fossil fuel.

Natural Gas (NG) is methane. CNG is compressed Methane. 2G CBG is compressed methane produced from Biomass. All biomass is organic. When biomass is digested by the consortia of bacteria, Methane, Carbon dioxide and certain other gases are liberated in the process. When we separate this Methane from the rest of the gases and compress it, the resulting gas is called 2G CBG. We may note that this is a derived Methane and not extracted. Primove’s brand of 2G CBG is called “AgroGaz®”.

CNG and 2G CBG both have almost similar contents and configuration rendering it at par with each other as far as application is concerned. While in CNG, Methane co-exists with other heavier hydrocarbons (for which the end application Stoichiometry – air fuel ratio is not adjusted), 2G CBG has only Methane in it. This makes 2G CBG more application friendly and efficient than fossil CNG.

Biomass is typically composed of Carbohydrates, Starch, Lipids, Proteins (grouped as polysaccharides), Cellulose, Hemi cellulose and Lignin. Depending on the source of biomass, Bio Fuels are classified in different generations.

When bio fuel is derived from digestion of polysaccharides (sugar, starch, vegetable oil or animal fats, and seeds or grains), it is called “first generation bio fuels”. When Bio fuel is produced from digestion/processing of Cellulose, Hemi cellulose (non-food crop and biodegradable wastes) it is called “second generation bio fuels”

AgroGaz® is a brand name – an acronym for 2G CBG produced by Primove Technology which is a second generation bio fuel technology. As the name suggests, Agro is input and Gas is output of the process. AgroGaz® principally produces 2G CBG using all kind of agro residue – Rice straw, Wheat straw, maize straw, Soya thrash, Cotton straw, Bagasse and even bamboo. The end product is Bio Methane/2G CBG as required.

Yes. Process deployed for AgroGaz® is a “Carbon Neutral Process”. What really makes it a “Carbon Neutral Cycle” is explained by way of a diagram below:

Carbon neutrality, or zero carbon footprint, refers to achieving net zero carbon emissions by balancing a measured amount of carbon released with an equivalent amount sequestered. In production of AgroGas, CO2 released in production process is consumed to grow further amount of biomass which is again used to produce AgroGas. Unlike fossil fuels where years of sequestered CO2 is released in high concentration in atmosphere in a very short span, AgroGas balances this sequestration and release of CO2 in a short span of about one year. This process efficiency qualifies AgroGas to be termed as environment friendly.

Primove’s technology produces AgroGaz® from biomass of all types such as Rice straw, Wheat straw, maize straw, Soya thrash, Cotton straw, Bagasse and even Bamboo.

Energy Farming is the concept of growing crops for production of energy. Napier grass and Bamboo are examples of energy crops.

The crop residue that remains in the field is ploughed directly into the ground or burnt first. A small percent of other crop residue which includes material left after crop is processed into usable resource (such as seeds, husks, roots, bagasse, etc.) is used as animal fodder and some of it is discarded.

AgroGaz® is a Automotive Fuel Grade Methane (AFGM) that can be used for cooking, industrial, commercial and vehicle filling application.

By using AgroGaz® you lessen the consumption of fossil fuels Petrol and Diesel. A large number of people using AgroGaz® would eventually result in causing economic benefit to our nation by reducing our oil imports. This would save our money as well as reduce our dependency on foreign energy.

Secondly, AgroGaz® is environment friendly. It is a Green Fuel produced by carbon neutral process. By using AgroGaz® we reduce the carbon footprint of our nation and make it a better place to live in.

Thirdly, by using AgroGaz® you indirectly help the farmer of your country in generating revenue through sale of their agro residue.

CNG is not available in all cities currently. However with our AgroGaz® technology, providing nationwide availability is possible.

Same or less than CNG. It is economical.

2G CBG like CNG reduces tail pipe emissions.

2G CBG is being produced in India from Substrates like Spent wash from sugar factory and sewage water but not from Agro residue. For vehicular application, Primove is the first company to have met the standards set by the government of India.

The maintenance cost of 2G CBG vehicles will be same as petrol driven vehicles.

With the new age kits it is equivalent to CNG & Diesel and better than petrol.

Yes, AgroGaz® (2G CBG) is a Automotive Fuel Grade Methane (AFGM) which can be filled in all vehicles which run on CNG without any additional retrofit.

Yes, in the same manner as you fill today.

You need a Retrofit kit to convert a petrol car to run on dual fuel (Petrol and CNG).

Cost of the kit depends on the model of the car. The range is in between ₹ 25,000 – ₹ 35,000 for cars and approximately ₹ 3,00,000 for buses.

Yes and No. CNG can replace diesel partially and the kits are available only for few models. Very soon the technology would be available for all the segments and models.

Typically 5 Ton per Day generation of 2G CBG is the minimum production that should be carried out for economical viability. A plant of greater capacity can be worked out depending on availability of Land, Agro residue, and Capital investment available.

Total area required for 5MTD AgroGaz® plant with dispensing station is about 5 acres.

The balance solid waste and liquid waste which is completely utilized to generate AgroGaz® can be sold as manure which can fetch additional revenue.

The liquid discharged from the plant has nutrition value and can be sold as manure.

Typically a 5MTD plant would require 8 Labour, 3 Supervisors, 1 Manager, 2 Security, and 2 Staff members for office and accounts work.

A 5MTD plant required about 3500 kWh of Power units per day.

Yes, licences and approvals from following bodies are required to set up and operate AgroGaz® plant:

  • Petroleum and Explosives Safety Organization (PESO).
  • Ministry of New and Renewable Energy (MNRE)Social Science.

Simple payback period is about 3.5 years.

Yes, from nationalised and co-operative banks.

Selling price of AgroGaz® varies from place to place depending on operational expenses incurred and corresponding competitive fuel available. However, it would be in the range of ₹ 42.0 to ₹ 58.0 per kg of AgroGaz®.

5 Tons Per Day AgroGaz® can be filled in:

  • 70 buses (70 kg/fill)
  • 500 cars (10 kg/fill)
  • 800 auto rickshaws (6 kg/fill)
  • A combination of the above

No. It does not contaminate or dilute oil content. Absence of lead in AgroGaz® avoids fouling of plugs. This together reduces the chances of wear and tear thereby enhancing the engine life.

Range of flammability is narrow in case of AgroGaz®. AgroGaz® released in atmosphere at concentrations below 5% or above 15% will not burn making it a safer fuel. Also, it being lighter than air, it will dissipate easily without causing any harm to environment.

  • Fuel efficiency of vehicles with AgroGas is at par with conventional CNG.
  • One kg AgroGas gives 25% more mileage as compared with one litre petrol.

India produces total of about 700MMT gross crop residue annually. It is practically very difficult to process all of it considering logistics involved. However, figuratively, this quantity of agro residue has a potential to produce about 100 MMT of AgroGaz®.

India imports about 190 MMT of crude oil. 55% of this import could be substituted which is equivalent to about ₹ 3 lakh crore of foreign exchange.

Yes. We may have to add energy farming practices to produce 2G CBG on about 10% of India’s cultivable land.

India’s first 2G CBG dispensing gas station is established by Primove and is located at Pirangut, Pune.

AgroGaz® produced by Primove Engineering Pvt. Ltd. is India’s first 2G CBG for vehicular use.

AgroGaz® is compressed methane produced from Biomass. All biomass is organic and available in plenty. Unlike fossil fuels which take years to be produced through natural process and are sure to get exhausted in near future, AgroGaz® can be produced continuously from inexhaustible resource. We shall have no option but to switch to such a perennial fuel type. Hence, we term our product AgroGaz® as ‘the fuel of the future’.

Yes. Visit would be arranged only with a prior appointment.
