Pu-238 Production Feasibility Study

Space missions operating in the inner solar system usually rely on photovoltaic solar cells as primary power source. However, these photovoltaic cells are not appropriate for all space missions, either because the solar radiation is too weak to produce sufficient power within the limitations imposed by today’s solar cell technology and spacecraft mass and volume limitations, or because the timespan to be bridged by the batteries is too long (e.g. lunar or Martian nights).

An End of Life Strategy for Solar Power Satellites

Space Based Solar Power concepts promise the generation of large amounts of renewable power by launching vast Solar Power Satellites (SPS) into space and beaming the power back to rectennas on Earth. Due to diffraction physics, large scale arrays delivering 2GW of power to the ground will be on the order of a kilometre in length and have masses between 2,000 and 10,000 tonnes. As of January 2020, the amount of debris orbiting the Earth exceeded 8,000 metric tonnes.

Innovative High Energy Density Li-ion batteries operating at low temperature /HELT-Bat

During this activity, we were able to evaluate our electrochemical system with respect to: (i) silicon anode fabricated at an industrial scale equipment, (ii) pouch cells that were manufactured at different suppliers and tested by Airbus Defence and Space, and (iii) safety protocols.

In addition, we showed that standard graphitic-based chemistry cannot operate at low temperatures. Finally, we evaluated the Cost of Ownership of our products.

Battery-Less Low Temperature Avionics and System Study

Many types of science missions focus on Solar System targets with harsh thermal environments, such as Mars, the Moon, asteroids, comets, and other bodies at the fringes of the Solar System. Traditional spacecraft avionics rely on the storage of electrical energy in electrochemical systems (typically secondary batteries) for covering peak energy demands and periods where no electrical energy is generated (Lunar/Martian/cometary night, etc.).

Lunar ISRU Energy Storage and Electricity Generation (LIESEG)

Humankind tested its capacity to survive on the Moon’s surface for short periods of time through the Apollo missions almost 50 years ago. Since then, robotic missions to the Moon have spent periods lasting several days and nights on the satellite. However, many technological challenges arise when planning a lunar (robotic and/or manned) mission that is fully operational during the night. Among these challenges, the need for a power supply system for both day and night remains open.

Novel thermal energy storage and electricity generation for Moon exploration

One of the most critical points in the exploration of space beyond Earth orbit is the provision of systems which ensure the survival of both crew and technological assets, such as rovers an landers. The utilisation of the Moon, being the next logical step in implementing the global strategy for colonising the Solar System, is a focus of national and international space agencies.
