The United Kingdom is reportedly considering a £ 16 billion ($ 21 billion) proposal to build a solar power station in space.
Yes, you’ve read that right. Solar power in space is one of the technologies to be included in the Department of Business, Energy amp; Industrial Strategy Net Zero Innovation Portfolio. It has been identified as a possible solution, alongside others, to enable the UK to reach net zero by 2050.
But how would a solar power station in space work? What are the advantages and disadvantages of this technology?
Solar power in space involves collecting solar energy in space and transmitting it to Earth. Although the idea itself is not new, recent technological advances have made this prospect more achievable.
The space-based solar power system includes a solar-powered satellite – a huge spacecraft with solar panels. These panels generate electricity, which is then wirelessly transmitted to Earth via high frequency radio waves. An earth antenna, called a rectenna, is used to convert the radio waves into electricity, which is then delivered to the power grid.
A solar power station in space in orbit is illuminated by the Sun 24 hours a day and thus could generate electricity continuously. This represents an advantage over terrestrial solar power systems (ground based systems), which can only generate daytime electricity and depending on the weather.
With global energy demand expected to increase by nearly 50 percent by 2050, solar power in space could be key to helping meet the growing demand on the world energy sector and going to r tackle global temperature rise.
Space-based solar: Some challenges
A space-based solar power station is based on a modular design, in which a large number of solar modules are assembled by robots in orbit. On the same subject : San diego solar installation cost. Transporting all these elements into space is difficult, costly, and will affect the environment.
Solar panel pressures were identified as an early challenge. But this has been addressed by the development of ultra-light solar cells (solar panel includes smaller solar cells).
Solar power in space is considered technically feasible due to advances in key technologies, including light solar cells, wireless power transmissions, and space robotics.
Importantly, assembling even one solar power station into space will require many space shuttle launches. Although space-based solar power is designed to reduce carbon emissions in the long run, there are significant emissions associated with space launches, as well as costs.
Space shuttle is not currently reusable, although companies like SpaceX are working on changing this. Being able to reuse launch systems would significantly reduce the overall cost of solar power in space.

If we successfully build a solar power station in space, its operation also faces many practical challenges. Solar panels could be damaged by space debris. Furthermore, panels in space are not shaded by the Earth’s atmosphere. Exposure to more intense solar radiation means that they will degrade faster than those on Earth, which will reduce the power they can generate.
The efficiency of wireless power transmission is another issue. Transferring energy across great distances — in this case from solar satellite in space to earth — is difficult. Based on current technology, only a small proportion of solar energy collected would reach Earth.
Pilot projects are already underway
The Space Solar Power Project in the United States is developing high efficiency solar cells as well as a conversion and transmission system optimized for use in space. The US Navy Research Laboratory tested a solar module and space-based power conversion system in 2020. Meanwhile, China has announced progress on its Bishan space solar power station, with the goal of having an operating system by 2035.
In the UK, a £ 17 billion ($ 22 billion) space solar power development is considered a viable concept based on a recent Frazer-Nash Consultancy report. On the same subject : Solar hot water san diego. The project is expected to begin with small trials, culminating in a functioning solar power station in 2040.
The solar-powered satellite would be 1.7 kilometers (1.1 miles) in diameter, weighing about 2,000 tons. The terrestrial antenna takes up a lot of space – about 6.7 km (4.2 miles) by 13 km (8.1 miles). Given land use across the UK, it is more likely to be offshore.
This satellite would provide the UK with two gigawatts of power. Although this is a significant amount of power, it makes a small contribution to the UK’s production capacity of around 76 gigawatts.
With extremely high start-up costs and slow returns on investment, the project would require significant government resources as well as private company investments.
But as technology advances, the cost of launching space and manufacturing will gradually decrease. And the size of the project will allow for mass manufacturing, which should reduce the cost somewhat.
It remains to be seen whether solar power in space can help us reach net zero by 2050. Other technologies, such as variable and flexible energy storage, hydrogen and growth in renewable energy systems are better understood and can be applied ‘ easier.
Despite the challenges, solar power in space is a precursor to exciting research and development opportunities. In the future, technology is likely to play an important role in the global energy supply.
