WASHINGTON – The European Space Agency will seek funding this fall for a feasibility study on solar power in space, the latest sign of support for an idea that still faces major technical and financial challenges.
Josef Aschbacher, director general of ESA, tweeted on August 16 that he will ask the member states at the meeting in November to finance the program of preparation of solar energy based (SBSP) called Solaris. He did not disclose the amount of funding Solaris is asking for.
“We already have the main buildings, but let’s be clear: for the project to be successful, the development of technology and a lot of funding are still needed,” he wrote.
Solaris, according to ESA, will be a three-year study to address technical issues related to SBSP, the concept of converting solar energy into electricity and then beaming it back to Earth for use on Earth. The study will examine potential business opportunities for SBSP development and addressing policy issues.
“It will ensure that Europe becomes an important player – and a potential leader – in the global competition for scalable clean energy solutions to mitigate climate change,” ESA said on the Solaris website. The three-year study will support the decision of the next ministerial meeting in 2025 on the continuation of the comprehensive SBSP development effort.
ESA is requesting funding for Solaris following two independent cost-benefit studies by consulting firms Frazer-Nash in the United Kingdom and Roland Berger in Germany. Both concluded SBSP has the potential to meet Europe’s energy needs while supporting the “net zero” emissions goal by 2050 set by the European Commission.
The Frazer-Nash study estimates that the net present value of the SBSP system in Europe from 2022 to 2070 is between 149 billion and 262 billion euros ($150-264 billion). A central case of 54 “gigawatt-class” satellites SBSP will generate 601 billion euros in benefits during that period, primarily from the protection of costs of energy production on the ground together with carbon dioxide emissions, with 418 billion euros in costs to developed and operated SBSP system.
The Roland Berger study concluded that a single SBSP satellite, based on the current design, could cost as little as 8.1 billion euros to build and 7.5 billion euros to operate for 30 years, with assuming “significant progress” in key technologies. In the worst case scenario if no improvements are made, a similar design would cost 33.4 billion euros to build and 31.1 billion euros to operate. Despite the uncertainty, she concluded SBSP “has a strong potential to become a renewable technology.”
The ESA initiative comes amid a resurgence of global interest in the SBSP, which first had its heyday in half a century and has been periodically renewed since then. The UK government has expressed interest in SBSP, among other alternative energy technologies it has been considering for the past year.
The Chinese Academy of Aerospace Technology announced in June that it will test wireless power transmission, a technology essential to SBSP, in low-Earth orbit in 2028 followed by a megawatt-class test satellite in orbit. geostationary as soon as 2030. The experiments are part of a long-term effort that could result in satellites producing two gigawatts of electricity in GEO by 2050.
NASA’s Office of Technology, Policy and Strategy announced at the International Space Station Development Conference (ISDC) in May that it is conducting a short-term study on SBSP, updating existing concepts to reflect technological advances and reducing launch costs. The agency hopes to complete the study in time to present it at the International Astronautical Congress in Paris in September.
SBSP advocates say the potential for significant reductions in launch costs enabled by systems like SpaceX’s Starship, coupled with the growing need for clean energy sources to meet clean energy goals, is driving interest in renewing SBSP from governments. . However, even those who advocate it admit that SBSP faces major challenges, from the economics of these systems to the development of key technologies needed to assemble and operate large satellites, as well as the political implications related to lighting. space light.
