Space-based Solar Power for Net Zero 

An international workshop to plan ESA’s next steps towards providing clean energy from space for a greener Earth.

Want to know about how space could provide clean energy to society to enable the transition to a Net Zero carbon world by 2050?

Interested to find out what the European Space Agency is doing to see if the idea of collecting energy in space and sending it to Earth is credible and realisable?

Then please join us online on December 9th and 10th, both days from 12:00 to 18:00 pm CET, to meet and hear from international experts in the field and to discuss and learn about the vital role that Space-based Solar Power  (SBSP) could play in the fight against climate change and help ESA shape its future programmes.

What is Space-based Solar Power (SBSP)?

Space-based solar power is an emerging technology for electricity generation that could provide a limitless source of continuous clean energy to help power our green future. Like terrestrial solar photovoltaic (PV) technology, it harnesses the power of sunlight and converts it into useable electricity. The difference is that it does this in space and delivers the energy to the ground in a continuous manner due to the 24/7/365 availability of sunlight in space which overcomes the intermittency of terrestrial renewables like wind and terrestrial solar which regularly cannot provide power when the wind is not blowing or the sun is not shining. Currently however, despite the potential benefits of SBSP, relatively little research and development in this technology is being pursued internationally, compared to alternative green energy sources.

What is this “Space-based Solar Power for Net Zero” international workshop about?

Following on from previous ESA studies in the mid-2000’s, ESA believes that it is very timely now for the potential and feasibility of SBSP to be more deeply investigated in order to understand whether or not such a technology could be a realistic new source of clean energy for Europe and the world to help with the transition to Net Zero by 2050. As a first step in this direction, this workshop has the objective to define a roadmap of activities for ESA (with support from industry and international partners) to pursue over the next 12 months which could potentially lead to the initiation of a renewed and substantial European/international effort for the development of SBSP for terrestrial energy needs.

The workshop will bring together key international experts from Europe, the US, Japan, China, South Korea, and Australia to describe the state of the art in SBSP, experts from terrestrial energy generation industries, national policy makers and international energy agencies. Key questions to be discussed include: Why it is timely for Europe to decide on whether it will pursue SBSP? What is holding terrestrial energy providers back from investing in SBSP? And what would be the most useful activities to be spearheaded by ESA in the next 12 months that could by the end of 2022 provide a sufficient basis for Europe to embark on a major SBSP development program.

What other steps is ESA taking to explore whether SBSP has a viable path towards commercialisation and contribution to Europe’s Net Zero goals?

Alongside the aforementioned workshop and on-going ESA-funded early R&D efforts on SBSP, a new ESA ITT is now open for a cost vs. benefits analysis study to evaluate the ‘business case’ for space-based solar power as a potential new source of clean energy for Europe. The results of the study, expected by mid-2022, will also help inform the next steps to be taken by ESA and Europe for this promising new capability that could help us secure a bright and sustainable future for our planet. Deadline to apply for the study is December 22, 2021!

Please plan to join us to learn about the vital role SBSP could have in the fight against climate change and help shape ESA’s future programmes.
