Manufacturing woes, Pg6

Key Highlights:

• India aims for 500 GW non-fossil fuel capacity by 2030 using Production Linked Incentive (PLI) schemes.
• PLI seeks to transform India into a global green technology manufacturing hub.
• Solar photovoltaic and advanced chemistry cell battery storage PLI face implementation challenges.
• Upstream segments like polysilicon and wafer manufacturing lag, reaching only 14% and 10% of targets respectively by mid-2025.
• Battery manufacturing progresses slowly, with only 1.4 GWh of 50 GWh targeted capacity commissioned by late 2025.
• Stringent domestic value addition requirements and technical barriers hinder battery production.

Detailed Insights:

• The PLI scheme for telecom manufacturing inspired the expansion into green technology, but faces different challenges.
• Downstream module assembly in solar achieves 56% of its target by mid-2025, while upstream segments struggle.
• Reliance on imported raw materials and specialized technical expertise persists in solar manufacturing.
• Government considers additional capital subsidies to de-risk high-capex upstream solar projects.
• Battery manufacturing is hindered by stringent domestic value addition requirements: 25% in two years and 60% in five.
• Technical barriers of "gigafactory" construction and visa issues for technical experts further impede battery production.
• Expectation that capital support alone will improve high-technology manufacturing is viewed as misplaced.
• Complex infrastructure requires decades of research investment and workforce training.
• Prioritizing expertise and technical know-how over net worth in PLI contracts is necessary.

Scientific/Technical Concepts Involved:

• Polysilicon: A high-purity form of silicon used as a raw material for manufacturing solar cells and semiconductors.
• Photovoltaics: The conversion of light into electricity using semiconducting materials.
• Advanced Chemistry Cell (ACC): New generation battery technologies for electric vehicles and energy storage.
• Gigafactory: A large-scale manufacturing facility, especially for producing batteries.
