Industrial Thermal Energy Alternatives and Fuel Switching Trend Analysis

Introduction

Industrial thermal energy demand has always been and still is a major driving force of manufacturing in various sectors, such as food processing, ceramics, chemicals, textiles and light engineering. It is true that electricity is the main source for most low temperature applications; however, many industrial processes still rely on combustion based thermal energy for consistency and controllability.

LPG occupies a transitional position within this landscape. It is not always the main energy source but is increasingly being considered as an alternative or backup fuel option in the absence of the pipeline gas or tightening of environmental compliance requirements.

Industrial fuel switching decisions are increasingly being influenced by factors other than just costs. Reliability of supply, emissions performance, installation timelines and exposure to regulations are now all significant factors that industries have to consider in their procurement strategies.

Businesses in gas unserved areas without a natural gas pipeline often have no alternative but to rely on liquid fuels like furnace oil or diesel. Yet the manufacturers are being forced to look at these options in a different light due to the implementation of stricter emissions standards and the risks associated with fuel handling.

LPG provides a number of operational benefits including cleaner combustion, lower particulate emissions and being easier to store compared to the heavy fuel oils. This is why the industries which are in need of compliance upgrades but do not want a major process redesign find it attractive.

In India, for example, industrial clusters in ceramics and food processing have gradually increased LPG usage where piped gas infrastructure remains uneven. These clusters have gradually increased the use of LPG even though the piped gas infrastructure is still uneven. Industry associations and energy suppliers have admitted that LPG allows for faster conversion timelines than pipeline-based alternatives.

Likewise, in certain parts of Southeast Asia, LPG continues to be a practical industrial fuel as biomass availability varies with seasons and electricity tariffs are unstable. When industries assess thermal energy alternatives, LPG is frequently weighed against three other parallel options, namely natural gas, electricity, and biomass-based systems.

Natural gas can provide cost and emissions advantages if it is available but being dependent on pipelines and supply disruptions will always be the main issues. Electricity is accurate but it can be very costly for high heat processes and it can expose users to grid reliability risks. Manufacturers oriented towards sustainability are attracted by biomass solutions, however, such solutions entail constant supply of feedstock and larger footprint. Also, in urban industrial zones, storage, handling, and ash disposal may complicate the operations.

In this situation, LPG acts as a versatile energy carrier. It is effective for both standalone use and also in hybrid systems where manufacturers can balance the load across different fuels according to the operational conditions.

Market Driver, Trends and Challenges

One factor that continues to make LPG a highly industrially relevant fuel is that it is compatible with the existing combustion equipment. In most cases, boilers, kilns, and ovens may be LPG, fired after modification of the burner, without the need for a complete system change. This results in lower capital expenditure and less production downtime during the conversion process. Generally, equipment manufacturers and industrial gas suppliers intend the conversion to LPG as a temporary or modular step rather than a final solution.

In regulated markets such flexibility has value. Industries that are subject to phased emission standards would rather have incremental compliance options than entirely disruptive overhauls. European industrial users in the small and medium manufacturing segments especially have been using LPG for off grid operations for quite a while now. Such a usage scenario is indicative of how LPG can be a part of decentralized industrial energy systems without being reliant on large, scale infrastructure.

From a strategic standpoint, industrial fuel choices nowadays take into consideration flexibility as opposed to sustainability commitments that are done in the long term. LPG allows manufacturers to keep their operations running smoothly while at the same time, they are planning for a gradual shift to lower carbon energy systems.

Thus, for suppliers and distributors, this is opening doors to offering LPG not as an individual commodity but as a part of a bundle of energy solutions. Differentiators in such a case become the provision of services like on, site storage management, guarantees of supply reliability, and technical support.

As industries continue to diversify their energy mix, LPG will most probably continue to be there where the constraints of the grid, the gaps in the infrastructures, and the regulatory timelines.
