The main objective of the PERTE project is to develop a residential e-HUB system for electrical energy flow management, based on a bidirectional electric vehicle charger and a second-life battery. This system will enable the integration of renewable energy sources, optimize household energy consumption and storage, and make use of the electric vehicle battery to supply power to the home, the grid, or the residential battery.

The project consortium is coordinated by SEAT S.A., which acts as the consortium’s lead and main interlocutor, ensuring effective coordination among all partners and serving as the primary point of contact for the project.

In addition, the system will incorporate an artificial intelligence platform that will manage energy flows based on weather forecasts, electricity prices, and consumption patterns. It will be capable of operating either in an economic mode, which minimizes energy costs, or in an ecological mode, which prioritizes the use of renewable energy sources.

STRATOSENS is an R&D project led by Airbus (through its subsidiary AIRBUS DS GEO), in collaboration with Power Innotech, part of the GPAInnova Group. The project aims to develop a new generation of payload technologies for High-Altitude Platform Systems (HAPS): unmanned aircraft operating in the stratosphere at an altitude of approximately 20 km, capable of remaining over a target area for several months while performing functions similar to those of satellites, but with greater flexibility and at significantly lower cost.

The project is based on the premise that, unlike HAPS platforms themselves, payload technology (including cameras, sensors, and electronic systems) has seen very limited advancement. Current payloads can only accommodate a single high-resolution sensor, are not designed to withstand the extreme environmental conditions of the stratosphere, generate more data than can be transmitted in real time, and are typically discarded after each flight. To address these limitations, the project focuses on four main technological developments: onboard data processing to reduce the volume of information requiring transmission; an ultra-lightweight optical system integrating both visible and infrared sensors within a single payload; high-precision pointing mechanisms capable of compensating for platform vibrations; and a redesigned structural and thermal architecture that enables payload reuse instead of disposal after each mission.

The project is also supported by i2CAT, IEEC, LEITAT, and the University of Vigo. It has a total budget of approximately €5.6 million and is scheduled to run from October 2024 to December 2026. Its objective is to position Spain as a European leader in HAPS payload technologies while enabling new applications in areas such as maritime surveillance, wildfire detection, precision agriculture, and emergency management.
