Tata Steel is a global steel manufacturing company headquartered in India. Like many heavy industries, steel production involves numerous processes that generate a significant amount of waste heat, which is often considered "low-grade" heat due to its relatively low temperature (150-200 degrees Celsius). Unless recovered, this waste heat is released into the environment, contributing to energy loss and impacting the environment.

Tata Steel is looking for an innovative solution to capture, recover, and effectively utilise the waste heat generated during their steel production processes. By doing so, they aim to achieve several objectives:

  • Energy Efficiency: Recovering and utilising low-grade waste heat enhances the overall energy efficiency of the steel production process. This results in reduced energy consumption, which in turn lowers operational costs and environmental impact.
  • Resource Conservation: Converting waste heat into usable energy resources help conserve valuable natural resources that would otherwise be used to generate the energy required for various processes. There can also be cost savings here.
  • Environmental Impact: By optimising the recovery and utilisation of waste heat, Tata Steel aims to reduce its carbon footprint and other environmental emissions associated with energy consumption.
How might we optimise the recovery of low-grade heat waste (150-200 degrees Celsius) and redirect the heat to a productive use within the steel plant?

Many industrial processes require a significant amount of energy for heating, cooling, and various other operations. Maximising the recovery and utilisation of low-grade heat can greatly contribute to improving the overall energy efficiency of these processes.


  • The heat recovery system should capture and convert low-grade waste heat (150-200 degrees Celsius) into usable energy to power equipment or for heating purposes. Your solution should include an integrated process that optimises the utilisation of waste heat within the steel production facility itself.

  • Technologies like thermoelectric generators, Organic Rankine Cycle (ORC) systems, and heat pumps to efficiently convert waste heat into electricity can be explored. Integration should minimise interference with the existing plant setup as much as possible.

  • The solution should be able to achieve one of the following: 
    > Heat-to-Power (ideal)
    > Heat-to-Heat


The POC/pilot is most likely to be performed at Tata Steel Jamshedpur, India. Data will be shared with the startup after a Non-Disclosure Agreement (NDA) has been signed. 

The average expected timeline of such an on-ground deployment pilot is 15-18 months. The timeline of the project will be considered and developed on a case-by-case basis.

Resources and incentives

TS Procurement Company is providing funding of up to S$82,000 for a trial. This budget can be increased depending on the requirements and merit of the solution. 

Enterprise Singapore is augmenting this support with a S$20,000 POC development grant. This POC development grant will be made available to solution providers, both local and foreign, provided that they engage in innovation development activities in Singapore.

Market Potential / Business Opportunity

There could be potential cross-deployment opportunities at different Tata Steel facilities.

Other Considerations

The ideal startup partner would be between TRL level 5-8. This would help Tata Steel quickly conduct a POC / pilot.
