The Aerospace Technology Institute (ATI) has defended its investments in hydrogen-related projects following Airbus' announcement of delays in its hydrogen-powered aircraft programme. Airbus disclosed concerns regarding technology and infrastructure, potentially pushing back service entry to around 2045. This delay has impacted the supply chain, leading to adjustments in research and technology plans for several ATI-backed projects. Despite facing questions about its funding strategy, the ATI remains confident in the viability of hydrogen as an aircraft fuel. Tom Halhead, head of technology at ATI, emphasized the attractiveness of hydrogen as a fuel for aviation based on internal evaluations like the FlyZero study. Although acknowledging challenges in hydrogen deployment, Halhead highlighted the absence of major technical barriers that could halt progress. The ATI's strategy involves investing in critical technologies, such as liquid hydrogen storage systems and fuel cell systems, to support future hydrogen flight capabilities. David Debney, ATI's head of technology, underlined the importance of developing lightweight and durable hydrogen distribution and storage systems to meet aviation requirements. Recent ATI-supported projects include efforts by ZeroAvia and Intelligent Energy to advance liquid hydrogen storage and fuel cell technology. These initiatives aim to enhance hydrogen flight capabilities and drive innovation in sustainable aviation. The ATI's long-term commitment to hydrogen is reinforced by a substantial 10-year funding pledge from the UK government. This funding, amounting to £2.3 billion, signifies a strategic vision to propel research, development, and technology advancements in carbon-neutral aviation. By continuing to invest in hydrogen technology, the ATI aims to accelerate progress towards achieving sustainable and efficient hydrogen-powered flight in the future.
