Overview Energy wants to launch #satellites 🛰️ into space that are equipped with #solar panels that convert sunlight into electricity. With this electricity, the company wants to generate laser light in the near-infrared spectrum. The satellites are to be positioned in a geostationary orbit, about 36,000 kilometers above the Earth.

#SolarPanels in space 🌌 could provide 80% of #Europe’s renewable energy by 📆 2050 https://www.theguardian.com/environment/2025/aug/21/solar-panels-in-space-could-provide-80-of-europes-renewable-energy-by-2050

• Current international state of the art of #SBSP
• #ESA activities related to SBSP
http://large.stanford.edu/courses/2024/ph240/ferretti1/docs/esa-may22.pdf

2022, #ESA awarded two parallel cost-benefit analysis studies, which will evaluate the ‘business case’ for space-based solar power in #Europe 🇪🇺 https://www.esa.int/Enabling_Support/Preparing_for_the_Future/Discovery_and_Preparation/ESA_reignites_space-based_solar_power_research

With a fraction of the investment directed at other technologies, 90% of the barriers to #SBSP could be de-risked within five years, preparing it to scale 📈. The intensity of sunlight in space 🌌 is significantly higher, meaning space-based panels generate far more #energy 🔋 per square metre than their terrestrial counterparts, freeing up valuable land.
This superior energy density also translates into a dramatic reduction in material usage https://www.weforum.org/stories/2025/10/space-based-solar-power-energy-transition/

Is #space based #solar power feasible? And viable? Honoured to be invited to give a talk to the Tweeddale Astronomical Society on

Solar Power from Space

#Silicon is relatively heavy and inflexible. In contrast, organic #SolarCells ☀️ can be #flexible and are much lighter. Organic solar cells made with small molecules showed no damage after three years worth of #radiation ☢️ https://news.umich.edu/light-flexible-and-radiation-resistant-organic-solar-cells-for-space/

#SBSP #FlexibleSolarCells #University #Michigan

Growing efficiencies of near-infrared #lasers make them preferable over #microwaves, allowing the transmission antenna on the spacecraft to be scaled down from hundreds of meters across to about half a meter 📏. #OverviewEnergy successfully tested a system that transmitted “multiple thousands of watts” of power using a near-infrared laser from an aircraft flying at an altitude of 5,000 meters to a receiver on the ground https://spacenews.com/overview-energy-demonstrates-technologies-for-space-solar-power/

The primary obstacle has always been #LaunchCost, but the advent of #reusable ♻️ rockets is rapidly changing the economics of space access, making the financial case for #SBSP increasingly attractive https://www.weforum.org/stories/2025/10/space-based-solar-power-energy-transition/

📊 2025 : The simulations show that if the swarm design can deliver #electricity at six to nine times the projected 2050 cost of ground PV, system #costs fall by 7%–15% 📉. At that price, #space -based #solar ☀️ can displace up to 80% of wind-plus-solar capacity and cut #battery needs by more than 70% https://www.sciencedirect.com/science/article/pii/S2542435125002557

#SBSP #SolarPower #Photovoltaics #PV

Based on the cost 💶 assumption of #SBSP, the projected value-adjusted levelised cost could even reach 69 EUR/MWh for the first system. Applying a learning curve metric already shows cost reduction potential in the setup of the first 10 SPS station deployments, leading to an estimated VALCoE of 49 EUR/MWh. This means that SBSP has the potential to even become a cost-competitive renewable technology https://www.rolandberger.com/en/Insights/Publications/Space-based-solar-power.html

The #UK 🇬🇧, #US 🇺🇸, #Japan 🇯🇵 and #China 🇨🇳 are now investing in #space based solar ☀️ power. The #atmosphere reflects around 30% of the #energy that reaches our planet while it absorbs around a quarter before it even reaches the Earth's surface. Space-based 🌌 solar panels can avoid this effect, but can remain in near-constant sunlight https://www.bbc.com/future/article/20251029-the-beam-dream-should-we-build-solar-farms-in-space

@slow_developer

Amazon CEO, Jeff #Bezos:

Within 10-20 years, the giant, gigawatt-scale data centers for #AI training clusters will be built in space

This would leverage 24/7 solar power and make space a key part of Earth's industrial and technological infrastructure

How can #SBSP be competitive with terrestrial renewables (e.g., #solar, #wind), when the cost of renewables is falling rapidly and given the typically high costs of #launch and space hardware ?

SBSP could serve a complementary role to terrestrial #intermittent renewables, helping to provide #stability and #reliability to the grid. The remaining #energy received at Earth could still be sufficient to make it a worthwhile and economically viable proposition. https://www.esa.int/Enabling_Support/Space_Engineering_Technology/SOLARIS/FAQ_Frequently_Asked_Questions_on_Space-Based_Solar_Power

Space-based solar ☀️ power (#SBSP) - beaming clean #energy to #Earth from orbital #solar farms.

The #UK 🇬🇧, #US 🇺🇸 and #Chinese 🇨🇳 governments are funding research, #ESA 🇪🇺 has approved a 3-year study named #Solaris.

One reason that #SPSB is back on the agenda is the plummeting #cost per kilogram of launching #payloads into #space.
Thanks to #reusable #rockets, this figure has fallen nearly 20-fold in two decades, while solar panels have become #lighter. https://www.abc.net.au/news/science/2022-12-20/space-based-solar-power-europe-funding-research/101733558

@sciencemagazine The biggest boost has come from falling #launch #costs. A #solar #power #satellite will need to be #kilometers across, demanding hundreds of launches.
A #SpaceX Falcon 9 #rocket lofts cargo at about $2600 per kilogram—less than 5% of what it cost on the #SpaceShuttle—and the company promises rates of just $10 💵 per kilogram on its gigantic #Starship, due for its first launch this year. https://www.science.org/content/article/space-based-solar-power-getting-serious-can-it-solve-earth-s-energy-woes
