Context:
India is exploring electrification of industrial heat and Concentrated Solar Thermal (CST) technologies to reduce dependence on imported fuels and achieve thermal independence amid global energy uncertainties.
Key Highlights:
- Industrial Challenges
- Industrial hubs like Morbi (Gujarat) and Ludhiana (Punjab) face gas shortages due to geopolitical tensions.
- Gas allocation reduced to 65–80% of contracted supply.
- Emerging Solutions
- Electrification of heat (induction, plasma heating) gaining traction.
- CST technology offers renewable heat generation.
- Efficiency Advantage
- Electrification achieves >90% efficiency, compared to gas boilers (70–80%).
- Untapped CST Potential
- India has ~15 GW CST potential, but adoption remains limited.
- Rising gas prices improving economic viability.
- Infrastructure Constraints
- Need for grid upgrades, storage systems, and transmission capacity.
- Global Best Practices
- Oman’s Miraah project, Spain’s solar heat initiatives, Denmark’s heat purchase agreements.
