From AI to EVs, demand for semiconductors is exploding, but silicon is hitting its limits. Making more efficient chips requires new materials, ones far less ubiquitous than sand, but the solution might be out there — literally.
Space Forge, a U.K. startup headquartered in Cardiff, Wales, recently raised a £22.6 million (approximately $30 million) Series A to make wafer materials in space, where unique conditions unlock new possibilities.
For instance, the Welsh startup earlier won funding for a project through which BT (formerly British Telecom) is hoping to test how integrating crystal materials grown in space could reduce the power consumption of its 5G towers. Because of weightlessness and other properties, crystals made in space have fewer defects, which can help devices use less energy.
Real-world use cases like this help Space Forge convey the message that critical systems could use its technology as an invisible backbone. The whole idea of making chips in orbit may sound like science fiction, but its feasibility has been known since the 1970s, CEO Joshua Western told TechCrunch.
“We’re stood on the shoulders of about 50 years of research when it comes to not only knowing that this is possible, but also knowing that there is a profound improvement in doing so,” Western said.
The improvement in question is obtaining crystals and advanced semiconductor materials with fewer defects and enhanced performance, making them appealing for use in applications such as quantum computing and defense systems.
This dual-use potential explains why NATO Innovation Fund led Space Forge’s Series A, and why major U.S. defense contractor Northrop Grumman is one of its partners.
Partners will be key to Space Forge’s trajectory: The company won’t build rockets and is instead relying on existing space providers for the launch part — a “solved problem,” in Western’s words.
It’s not just the rockets; from chip manufacturing to space return, Space Forge is tying together technologies that may be described as solved problems, at least on paper. But if you ask Western about its moat, he has a quick retort: “How bloody hard is it to do?!”
That’s the price to pay to take advantage of space’s unique environment: It requires adapting to harsh conditions such as extreme temperatures and microgravity, Western said. “Physics has the answers, and engineering is how you actually get there.”
