The company said it will partner with Overview Energy to develop up to 1 GW of space-based solar capacity, alongside a separate agreement with Noon Energy to deploy up to 1 GW/100 GWh of long-duration energy storage. Neither technology has yet been demonstrated at scale.

Under the first partnership, Overview Energy plans to collect solar power using satellites positioned in orbit around 22,000 miles above the Earth, where sunlight is continuous. The satellites, positioned in a geosynchronous orbit so that they rotate with the Earth and thus appear fixed in the sky, would transmit solar radiation as low-intensity near-infrared light to existing solar farms on the ground. This arrangement would enable them to generate electricity continuously, day and night.

Meta said the approach could increase the output of existing solar infrastructure without requiring additional land or significant grid upgrades.

Overview Energy is targeting an orbital demonstration in 2028. If successful, Meta commercial delivery to the US grid could begin as early as 2030.

Back on Earth, Meta has also partnered with Noon Energy to explore longer-duration energy storage, up to 100 hours, far longer than the duration of lithium-ion batteries. In this case, it consists of solid oxide fuel cells. When electricity is supplied, they store energy in a carbon-based storage medium and release oxygen to the atmosphere. When electricity is required, the process reverses.

Noon Energy’s 25 MW/2.5 GWh-capacity pilot project is expected to be completed in 2028. Meta has reserved up to 1 GW/100 GWh of capacity.

Ceres launches onsite solid oxide platform 

Meanwhile, UK-based Ceres has launched Ceres Endura, a solid oxide fuel cell stack platform designed to provide onsite power for data centres and other energy intensive facilities.

The company said the platform is designed for both power generation and hydrogen production from a single manufacturing base, allowing deployment across multiple applications.

Systems can initially operate on natural gas, with the potential to transition to hydrogen and other lower-carbon fuels. Ceres said installations can be deployed within months, offering an alternative to longer grid connection timelines.

The platform supports high-voltage direct current architectures of 800 Volts and above, aligning with data centre design standards.

Ceres added that the system operates at lower temperatures (450–630°C) than conventional solid oxide technologies, enabling the use of more widely available and recyclable materials while reducing cost by a third compared to competitor products.
