Can data centres in orbit solve for AI models’ soaring energy demand?

Political & Constitutional Dimensions:

The emergence of space-based data centre technology raises significant questions about technological sovereignty and strategic autonomy. India's inclusion in this domain through ISRO's reported studies aligns with the government's Atmanirbhar Bharat initiative in strategic technologies. The Outer Space Treaty of 1967, to which India is a signatory, establishes that outer space is not subject to national appropriation, but the commercial exploitation of orbital infrastructure remains an evolving legal framework. The positioning of data centres in orbit could create new jurisdictional complexities regarding data sovereignty—currently governed in India by the Digital Personal Data Protection Act, 2023. From a geopolitical perspective, space-based AI infrastructure could become another domain of great power competition, similar to terrestrial undersea cable networks that carry the majority of global internet traffic.

Economic & Financial Impact:

The $3 trillion projected investment in AI infrastructure by 2030 represents a fundamental shift in global capital allocation toward digital infrastructure. For India, this presents both opportunity and challenge. The country's data centre industry, concentrated in cities like Mumbai, Chennai, Hyderabad, and Pune, has been growing at approximately 20% annually. Space-based alternatives could disrupt this growth trajectory. Google's projection of launch costs declining to $200 per kilogram by the mid-2030s suggests potential cost competitiveness, but this remains speculative given current costs. The thermal management challenge in space—where direct solar exposure makes conventional cooling impossible—represents a significant operational cost factor that could affect economic viability.

Social Dimensions:

The energy consumption of AI data centres has environmental implications. Traditional data centres globally account for approximately 1-2% of electricity consumption, with AI workloads significantly increasing this share. Space-based solar power, if successfully deployed, could theoretically provide unlimited renewable energy for computing. However, the digital divide considerations are critical: if space-based infrastructure concentrates AI capabilities among a few tech giants, it could exacerbate technological inequalities between nations and communities. India's significant digital divide between urban and rural areas, where internet penetration remains uneven, raises questions about equitable access to AI capabilities enabled by such infrastructure.

Governance & Administrative Aspects:

The regulatory framework for space-based commercial infrastructure remains underdeveloped in most jurisdictions. In India, the Indian Space Research Organisation (ISRO) operates under the Department of Space, with commercial activities managed through NewSpace India Limited (NSIL), established in 2019. The proposal for space-based data centres would require significant regulatory evolution, including licensing frameworks for orbital data centre operations, spectrum allocation for inter-satellite and Earth-space communications, and liability frameworks for potential satellite failures or debris generation. The International Telecommunication Union (ITU) manages spectrum allocation globally, and increased satellite deployments would require coordination through this body.

International Perspective:

Globally, several nations are exploring space-based solar power concepts. Japan's Aerospace Exploration Agency (JAXA) has researched space-based solar power since the 1980s, viewing it as a potential solution to energy security concerns. China's space programme has also expressed interest in orbital solar power stations. The Starlink precedent—where initial skepticism proved unwarranted as the constellation achieved global coverage with practical speeds—suggests that space technology skepticism often fails to account for rapid technological evolution. However, Microsoft's abandonment of the Natick underwater data centre project despite promising results demonstrates that not all innovative infrastructure concepts prove viable at scale.
