NLR and Cryoworld collaborate on flying with liquid hydrogen

NLR is taking a further step towards more sustainable flight by partnering with Cryoworld to develop a liquid hydrogen tank. This follows the agreement with zepp.solutions for a fuel cell system. The new collaboration contributes to NLR’s ambition to conduct a demonstration flight on liquid hydrogen in 2026.

R&D case COCOLIH2T – Composite Conformal Liquid H2 Tank

The global aviation industry is committed to reducing global net aviation carbon emissions by 50% by the year 2050, with the European Commission pursuing a more ambitious goal of a 75% reduction in CO2 emissions per passenger kilometre. Alternative fuels such as liquid hydrogen (LH2) are seen as playing a central role in a zero-emission future for aviation. To store cryogenic (20 K) liquid hydrogen in an aircraft, the COCOLIH2T project carries out research and testing for the design, manufacturing and testing of storage containers for new and existing aircraft designs.

The need for disruptive aircraft concepts to address climate change

The EU project EXAELIA aims to accelerate the reduction of aviation emissions and its climate and environmental impacts. The project will evaluate novel flying test beds which are needed for de-risking the development of future long-range aircraft, thereby also helping the European industry to maintain its market position in aviation. The project’s official kick-off meeting was held on 22 January 2025, in Amsterdam. The consortium is coordinated by NLR.

R&D case: Novel certification methods for disruptive technologies (CONCERTO)

CONCERTO is aiming to develop a comprehensive set of regulations for aircraft certification, together with a preliminary description of the Methods of Compliance (MoCs) that will apply to the three main thrusts of clean aviation: Hybrid-electric regional aircraft, Ultra-efficient short and short-medium range aircraft disruptive technologies for enabling hydrogen-powered aircraft. Furthermore, it aims to assess the feasibility of a digital certification framework that will help collaboration and model-based certification.
