Electrifying industrial heat as a path to India’s thermal independence, Pg11

Key Highlights:

• Gujarat's Morbi and Punjab's Ludhiana industrial hubs face challenges due to geopolitical tensions affecting natural gas imports.
• Ministry of Petroleum and Natural Gas reduced gas allocations to non-priority sectors to 65-80% of contracted volumes.
• Concentrated Solar Thermal (CST) technology and electrification of heat are emerging as solutions for thermal independence.
• India has a CST potential of 15 GW, but adoption remains low despite rising gas prices reducing payback periods.

Detailed Insights:

• Industrial heat, traditionally reliant on hydrocarbons, is shifting towards electrification using technologies like induction and plasma heating.
• Electrification of heat offers higher efficiency rates (over 90%) compared to gas boilers, which lose 20-30% energy in exhaust.
• India's grid infrastructure needs upgrades to handle the shift, including increased storage capacity and reinforced cabling.
• A National Thermal Policy is needed to incentivize direct-heat technologies like CST and reform the carbon market.
• Hybrid solutions, like integrating CST with gas-based backups and induction coils, can facilitate modernization without overhauling existing infrastructure.
• Global examples such as Oman's 'Miraah' project, Spain's 'Solar Heat for Industrial Processes', and Denmark's 'heat purchase agreements' offer valuable lessons.

Key Concepts Involved:

• Thermal Independence: A nation's ability to meet its heating needs from sovereign sources, reducing reliance on imports.
• Concentrated Solar Thermal (CST): Technology using mirrors to focus sunlight onto a receiver, heating a fluid for industrial processes.
• Carbon Credit Trading Scheme: A market-based system allowing entities to trade carbon credits, incentivizing emissions reduction.
