Researchers at BITS Pilani Hyderabad campus developed an innovative method to convert industrial waste gases into Dimethyl Ether (DME), a clean fuel that could potentially replace or supplement LPG in Indian households. The breakthrough offers a promising solution to two major challenges – reducing industrial emissions and strengthening India’s energy security. By converting gases that are typically released from power plants and heavy industries, the technology transforms a major pollution source into a valuable alternative fuel.
Research Led by BITS Pilani Scientists
The research initiative was led by Prof. Sounak Roy, Dean of Research and Innovation at BITS Pilani Hyderabad, along with Satyapaul A. Singh and retired professor B. M. Reddy. Their work demonstrates how smoke-like gases released from industrial facilities can be captured and converted into a clean-burning fuel. Instead of allowing these emissions to escape into the atmosphere, the team designed a process that recycles them into Dimethyl Ether, a fuel widely regarded as a clean alternative to conventional LPG. This development gains particular relevance at a time when geopolitical tensions in West Asia are affecting LPG supply chains, raising concerns about fuel availability and price stability in India.
Innovative Single-Step Conversion Process
The researchers developed a single-step catalytic process to convert waste gases into DME. In this process, the captured industrial gases are combined with hydrogen produced through water splitting, where water molecules are separated into hydrogen and oxygen. Using specially designed catalytic materials, the researchers successfully converted the gas mixture into Dimethyl Ether in a single reaction step. This approach simplifies the conversion process while improving efficiency, making it more suitable for large-scale industrial applications.
Simulating Real Industrial Conditions
To ensure the technology could work beyond laboratory conditions, the research team recreated industrial operating environments similar to those found in power plants. They used a specialized high-pressure reactor that allowed gases to flow rapidly through the system, mimicking the flow conditions of industrial chimneys and exhaust systems. By carefully controlling temperature, pressure, and gas composition, the researchers achieved significant DME production levels. These experiments demonstrate that the process has strong potential for future scale-up and commercial deployment.
Supporting India’s Clean Energy Transition
The breakthrough carries significant environmental benefits. By converting industrial emissions into usable fuel, the technology not only produces clean energy but also reduces carbon emissions. This dual advantage makes the process particularly valuable for energy-intensive sectors such as power, steel, and cement, where large volumes of exhaust gases are generated. By capturing and reusing these emissions, the technology contributes to lower industrial pollution while simultaneously producing a sustainable fuel source.
Reducing Dependence on Imported LPG
According to Prof. Sounak Roy, the innovation highlights the potential of turning industrial waste into strategic energy resources. “Our breakthrough shows that, instead of treating power, steel or cement plant emissions as waste, we can convert them into a valuable fuel that reduces dependence on imported LPG,” he said. As reported by telenganatoday.com, if successfully commercialized, the technology could play an important role in strengthening India’s energy independence while supporting its broader clean energy and decarbonization goals.
