India's aluminum sector seeks $ 29 bn for net-zero emissions

According to a study conducted by the Council on Energy, Environment, and Water (CEEW), India's aluminium industry requires an additional Rs 2.2 lakh trillion in capital expenditure (CAPEX) to achieve net-zero carbon emissions. The study pointed out that renewable energy (RE) could potentially reduce 49% of the industry's emissions, although relying entirely on RE poses challenges due to its intermittent nature.

The study highlighted that in the fiscal year 2019-20, the aluminium industry, a crucial sector in India's power and economy, emitted 77 million tonnes of CO2. Of these emissions, 80% were attributed to electricity consumption. Funded by 'bp', the study indicated that transitioning to a net-zero aluminium industry would incur a 61% increase in costs, with an additional Rs 260.49 billion in annual operating expenditure (OPEX).

CEEW's study introduced a marginal abatement cost (MAC) curve, outlining technologies capable of decarbonising the industry and their associated costs. Hemant Mallya, a CEEW Fellow, stressed the necessity of capital investment and scaling up from various sectors to align with India's climate objectives. He stated, "Aluminium and fertiliser industries require significant government support to establish essential infrastructure such as power grids and pipelines."

Furthermore, the study revealed that implementing energy efficiency measures in alumina refining, aluminium smelting, and waste heat recovery could reduce emissions by 8% without raising costs. Additionally, further decarbonisation measures, including RE and carbon capture, showed a positive MAC, implying net costs for facilities implementing these solutions.

Deepak Yadav, Programme Lead at CEEW, emphasised the importance of incentivising renewable energy, especially in eastern states with limited wind power potential. He advocated for the establishment of an R&D ecosystem to gather data on decarbonisation measures and the implementation of favorable policies to foster a carbon capture, utilisation, and storage (CCUS) ecosystem.

The study also addressed decarbonisation challenges faced by India's fertiliser industry, responsible for approximately 25 million tonnes of CO2 emissions annually due to energy-intensive processes and fossil fuel utilization. While transitioning to RE power could lead to a 2% reduction in emissions, shifting from grey to green ammonia production could result in a 151% emissions decrease, leading to net-negative emissions. Additionally, various carbon management options such as CCS, CCU, and afforestation were explored.

Tough Bidding Norms Slow NHAI Road Project Awards

Stringent bidding rules imposed by the Ministry of Road Transport & Highways (MoRTH) have led to a slowdown in project awards by the National Highways Authority of India (NHAI), despite a robust Rs 3.5 trillion pipeline. According to an HDFC Securities report, the shift to more cautious developer models now favours firms with strong balance sheets, as tighter qualification norms limit aggressive bidders.The revised norms mandate additional performance security, targeting the exclusion of players that previously submitted low bids—often 25 to 40 per cent below NHAI cost estimates—raisin..

Mumbai Gets Coastal Nod for Next Promenade Phase

As Mumbai prepares to open two major sections of its expansive seafront promenade this week, the city’s civic authority has secured a key coastal clearance to advance further construction. The Maharashtra Coastal Zone Management Authority (MCZMA) has approved the commencement of work on the segment between Haji Ali and Baroda Palace, with tendering expected soon after project cost assessments.The promenade, stretching 7.5 km in length and 20 metres wide, is being designed as a flagship open space for walkers, joggers, and cyclists. Two critical stretches—2.75 km from Tata Garden to Haji Al..
