On December 12th, 2025, the EIC Space Portfolio Webinar on “The Step-by Step Development Approaches and the Results toward the Realization of the Operational SSPS” brought together experts to explore the step-by-step development approaches and results towards the realization of the operational Space Solar Power System (SSPS). The webinar, organized by EIC Space Programme Manager Dr. Stella Tkatchova, featured Dr. Koichi Ijichi from Japan Space Systems (JSS), who shared valuable insights into the technological advancements and challenges involved in this innovative project.

Dr. Ijichi, a renowned expert in microwave power transmission (MPT), has been instrumental in advancing MPT technology, conducting successful tests, and developing Power Generation and Transmission Panels (PGTPs) as part of the SSPS project. He shared the current milestones in SSPS development, a revolutionary technology which aims to harness solar energy from space and transmit it to Earth, with operational deployment envisioned by 2050. Dr. Ijichi highlighted the potential of SSPS to revolutionize the clean energy sector by providing continuous, virtually unlimited power generation, regardless of terrestrial limitations such as the day-night cycle or weather conditions.

During the webinar, Dr. Ijichi also provided detailed updates on the various projects within JSS's Space Solar Power portfolio, including the ongoing OHISAMA project. This satellite-based initiative is focused on the critical phases of satellite and ground system design, with significant steps made in integration testing and the planning for future ground measurement systems in Japan.

The SSPS, which would collect solar energy in space and convert it into electromagnetic beams for terrestrial use, is a game-changing solution for clean energy, indeed, unlike conventional solar power systems that rely on Earth’s day-night cycle and weather conditions, SSPS would offer constant, high-intensity solar energy, contributing to a more sustainable future.

This vision aligns with the objectives of the RePowerSiC community, dedicated to fostering advancements in power generation and storage technologies. As SSPS technology matures, it promises to deliver a new frontier for global energy solutions, offering reliable and environmentally friendly alternatives to conventional power generation methods.

Dr. Ijichi’s presentation underscores the dedication and expertise of Japan Space Systems in pushing the boundaries of space technology for the benefit of humanity. As we continue to follow the progress of SSPS, RePowerSiC remains committed to supporting innovations that drive a greener and more sustainable future for all.
