London, United Kingdom – Harlette Capital Ltd, a UK-based innovation company, has launched its ALPHA LUNAR™ Small Modular Reactor (SMR) Request for Information (RFI) on Wednesday, 29 July 2026. The RFI invites leading nuclear technology organisations to collaborate on the development of a micro nuclear reactor designed for future sustained operations on the lunar surface.
The ALPHA LUNAR™ programme aims to explore the use of compact nuclear power systems incorporating innovative hydrogen-based technologies for long-term lunar infrastructure, scientific research, communications, robotics, and future human exploration.
Harlette Capital Ltd has invited industry leaders, including Rolls-Royce SMR and Westinghouse Electric Company, to participate in technical discussions and provide information on technologies that can support future lunar power generation.
This invitation comes after Harlette Capital Ltd’s participation in the International Conference on Topical Issues in Nuclear Installation Safety, held at the International Atomic Energy Agency (IAEA) Headquarters in Vienna, Austria, from 29 June to 3 July 2026. The conference focused on advances in nuclear safety, innovation, and future nuclear technologies.
The launch of the ALPHA LUNAR™ RFI also builds upon Harlette Capital Ltd’s engagement at a joint meeting between the United Nations Office for Outer Space Affairs (UNOOSA) and the International Atomic Energy Agency (IAEA) at the United Nations Headquarters in Vienna on 9 June 2026. At the meeting, representatives discussed the increasing importance of cooperation between the nuclear and space sectors in supporting future exploration beyond Earth.
The ALPHA LUNAR™ initiative aims to develop technologies that can deliver compact, lightweight lunar power systems with high reliability for continuous energy generation, integration of advanced hydrogen technologies, and safe deployment concepts for future international lunar missions. It also aims to support long-term energy needs for communications, scientific payloads, and critical infrastructure.
Harlette Capital Ltd believes that reliable nuclear power will be a crucial technology for the next generation of lunar exploration and commercial space development.
The Request for Information is an early-stage market engagement exercise to better understand current technological capabilities, future development pathways, and opportunities for collaboration between industry, research organisations, and international partners.
Harlette Capital Ltd welcomes responses from organisations with expertise in small modular reactors, microreactor technologies, nuclear safety engineering, hydrogen energy systems, space nuclear power, advanced materials, thermal management, radiation shielding, autonomous energy systems, and lunar infrastructure.
The company intends to use the information gathered through the RFI to inform future programme planning, technology partnerships, and potential research collaborations supporting the ALPHA LUNAR™ programme.
Founder of Harlette Capital Ltd, Harlette DeFalaise, said, “Reliable, compact nuclear power has the potential to become one of the foundational technologies enabling humanity’s long-term presence on the Moon. Through the ALPHA LUNAR™ Request for Information, we are engaging with world-leading innovators to better understand how advanced microreactor and hydrogen technologies may contribute to future lunar infrastructure in a safe and responsible manner. We look forward to constructive engagement with industry, research organisations, and international partners.”
Harlette Capital Ltd is an innovation company developing advanced technologies across aerospace, energy, communications, and emerging scientific research. The company is exploring concepts for next-generation energy systems to support future lunar exploration and long-term space infrastructure through its ALPHA LUNAR™ programme.
The ALPHA LUNAR™ Small Modular Reactor (SMR) programme is part of Harlette Capital Ltd’s ongoing efforts to further develop and commercialise research presented at the 76th International Astronautical Congress (IAC 2025). The company is progressing the programme under licence for continued research, engineering, and technology development.
The ALPHA LUNAR™ programme draws upon published research on future lunar infrastructure, including communications, environmental conditions, and long-term operations on the Moon. This research provides a scientific foundation for investigating resilient power systems for future lunar settlements and exploration architectures.
Harlette Capital Ltd believes that resilient lunar energy systems, advanced communications, and autonomous infrastructure should be developed together as integrated technologies. The RFI has been launched to identify nuclear industry partners with expertise in compact microreactor technologies, nuclear safety engineering, and innovative hydrogen-based energy concepts for future lunar applications.
The company considers the RFI a natural progression from its published IAC 2025 research programme and its engagement with international organisations, including the International Atomic Energy Agency (IAEA) and the United Nations Office for Outer Space Affairs (UNOOSA), supporting continued dialogue between the space and nuclear sectors.
Harlette Capital Ltd welcomes media enquiries from the United Kingdom.
This announcement concerns an early-stage Request for Information (RFI). The RFI is intended solely to gather technical information and explore potential collaboration opportunities. It does not constitute a procurement process, commitment to contract, funding decision, or announcement of a commercial partnership. Any future development activities will be subject to technical evaluation, regulatory requirements, and formal agreements where appropriate.
