UK prototype could pave way for constant energy all the time – from space

Luton based Electronics Design and Manufacturing company, Jaltek, whom have worked within the space sector for over 25 years, and are AS9100 accredited, have been part of a groundbreaking initiative that could see the first solar farm launched into space.

The successful demonstration of the World’s first prototype, which could pave the way to a constant supply of energy – from space – using 360-degree beam steering capability with no moving parts, is the innovation of Oxfordshire based company, Space Solar.

The consortium was made up of a talented team which was led by David Homfray, Mike Hontoir and Anja Frey of Space Solar and also included Neil Buchanan of Queens University Belfast (QUB), Debbie Fellows of Wave RF, Ian cash of International Electric Company and finally Jaltek.

The aim is to power more than a million homes by the 2030s with a mile-wide complex of mirrors and solar panels orbiting 22,000 miles above the plane. Solar panels capture 13 times more energy in space than they do on the ground because the light intensity is higher and there’s no atmosphere, clouds or night. Even though some energy would be lost by the time it is beamed back to Earth and connected to the electricity grid, it would still far outstrip solar generation on the ground. But it’s the production of power around the clock that makes space-based solar energy so attractive for providing a “baseload” to back up ground-based renewables. Currently, nuclear energy and gas turbines provide the baseload for the grid but produce radioactive waste or carbon dioxide respectively.  Space-based solar power is expected to provide baseload power but at a cost similar to intermittent renewables.

The first step was to build a prototype to demonstrate the technology on earth. During the initial concept meeting the team targeted a demonstrator within 8 months, with deadlines for hardware coming in August 2023 and December 2023, both of which were hit resulting in the working demonstrator in March 2024. The technology was shown to work for the first time at Queen’s University Belfast, with a wireless beam successfully “steered” across a lab to turn on a light.
