However, limited refuelling infrastructure can act as a barrier to fleets switching to biogas or CNG. Agility Fuel Solutions is breaking down these barriers by helping fleets go further between refuelling. In the UK, grocery giant Waitrose is now operating a fleet of 58 vehicles that operate using biomethane generated from their own food waste, contributing to truly closed loop value chain. Increasing the number of vehicles running on natural gas and biogas can significantly reduce the environmental impact of the transportation sector, which has so far proved very difficult to decarbonise.
Around four million people die from ambient air pollution every year. Using clean burning CNG and biogas could help improve air quality and mitigate respiratory illnesses. CNG and biomethane generate significantly less greenhouse gas than conventional fuel sources like diesel, and can help to cut emissions from the transport sector.
To fuel vehicles, biogas must be upgraded to a purity standard and either compressed for onsite dispensing or injected into the gas grid for distribution to dispersed fuelling locations. In the last decades, research organisations with a focus on rural energy security have enhanced the design of the systems resulting in newer efficient low cost designs such as the Deenabandhu model. LPG Liquefied Petroleum Gas is a key source of cooking fuel in urban India and its prices have been increasing along with the global fuel prices.
Also the heavy subsidies provided by the successive governments in promoting LPG as a domestic cooking fuel has become a financial burden renewing the focus on biogas as a cooking fuel alternative in urban establishments.
This has led to the development of prefabricated digesters for modular deployments as compared to RCC and cement structures which take a longer duration to construct.
Renewed focus on process technology like the Biourja process model has enhanced the stature of biogas in India as a potential alternative to LPG as primary cooking fuel. Increased Energy Security —Biogas offsets non-renewable resources, such as coal, oil, and fossil fuel-derived natural gas. Other renewable projects like solar, wind and water depend a lot on the geography of the project location.
A celebration of on-going activities on the Global Opportunity Explorer. In order to make compressed natural gas CNG and biogas more attractive alternatives to diesel and reduce emissions from heavy-duty vehicles, Agility Fuel Solutions has developed long-range, lightweight gas storage systems.

Floating biogas holders on the digester form a low-pressure storage option for biogas systems. These systems typically operate at pressures below 2 psi. Floating gas holders can be made of steel, fiberglass, or a flexible fabric. A separate tank may be used with a floating gas holder for the storage of the digestate and also storage of the raw biogas.
A major advantage of a digester with an integral gas storage component is the reduced capital cost of the system. The least expensive and most trouble-free gas holder is the flexible inflatable fabric top, as it does not react with the H 2 S in the biogas and is integral to the digester.
These types of covers are often used with plug-flow and complete-mix digesters. Thicknesses for cover materials typically vary from 0. Biogas can also be stored at medium pressure between 2 and psi. To prevent corrosion of the tank components and to ensure safe operation, the biogas must first be cleaned by removing H 2 S.
Next, the cleaned biogas must be slightly compressed prior to storage in tanks.
