The aviation industry poses a significant challenge to achieving the ambitious goals outlined by initiatives like the European Green Deal, aiming for net-zero greenhouse gas emissions by 2050 and stabilizing global temperatures at 1.5 °C above pre-industrial levels. In this context, Lighter-Than-Air (LTA) technologies emerge as promising solutions for decarbonization, providing a potential relief to the substantial emissions associated with traditional aviation practices. LTA vehicles, such as airships, leverage buoyancy to significantly reduce fuel consumption and emissions. Furthermore, modern technological advancements enable LTA technology to address pressing environmental concerns, including noise pollution, land use, and infrastructure requirements, all while ensuring heightened levels of safety and operational efficiency compared to previous initiatives. These advancements hold particular promise for critical sectors such as Intelligence, Surveillance, and Reconnaissance (ISR), monitoring, freight transport, and humanitarian aid. However, challenges such as weather-related operational constraints, scaling difficulties, and a notable lack of compelling and reliable data impede the development of current initiatives. Through a comparative analysis with conventional aviation technologies, this study underscores the potential of LTA technology to overcome existing operational limitations, while offering a more sustainable and environmentally friendly alternative.
