Meta is investing in space solar and long-duration storage to enable a continuous clean energy supply for data centers despite major uncertainties. This bold move aims to power its massive data centers around the clock with renewable energy, even when the sun isn't shining on Earth or the wind isn't blowing. By combining orbital solar panels with advanced battery systems, Meta hopes to solve one of the biggest challenges in tech: keeping data centers green and always-on.
Why Space Solar and Long-Duration Storage Matter for Data Centers
Data centers need huge amounts of electricity 24/7. Traditional solar and wind power are intermittent—they only work when weather conditions are right. Space-based solar power, collected by satellites in orbit, can capture sunlight 24 hours a day without clouds or nighttime. When paired with long-duration energy storage (like flow batteries or compressed air), that power can be stored and used during peak demand or outages.
How Meta's Plan Works
- Space solar arrays in geostationary orbit beam microwave energy down to receiving stations on Earth.
- Long-duration storage systems (4 to 24+ hours) store excess energy for later use.
- This combination provides a steady, clean power supply for data centers without relying on fossil fuels.
Key Benefits of This Approach
- Eliminates intermittency — space solar works day and night, rain or shine.
- Reduces carbon footprint — no backup diesel generators needed.
- Scalable — once the technology matures, it can power multiple data centers globally.
Challenges Meta Faces
Despite the promise, there are major uncertainties. Launching solar satellites is expensive and requires regulatory approval. Beaming energy to Earth also raises safety and efficiency questions. Long-duration storage technologies are still evolving, and costs remain high. However, Meta's investment signals confidence that these hurdles can be overcome.
What This Means for the Future of Clean Energy
If successful, Meta's project could set a new standard for how big tech companies source clean energy. It may also accelerate development of space-based renewables and grid-scale storage, benefiting everyone—not just data centers.
Expert Tips for Businesses Watching This Trend
- Monitor advances in space solar and long-duration storage — they may become viable options within 5–10 years.
- Consider pairing on-site solar with battery storage as a first step toward 24/7 renewable energy.
- Stay informed about energy regulations that could support or hinder space-based power projects.
Meta's investment in space solar and long-duration storage is a high-risk, high-reward bet. But if it pays off, it could transform how we power the digital world—making clean energy truly continuous.
