The growing demand for the production, storage and transportation of hydrogen -- as one of the most sustainable sources of clean energy - in most transportation sectors (e.g. aerospace) has been the main driver for this project. **Production**: ASG's in-house highly-efficient plastic recycling process, using Flash Joule Heating (FJH) is capable of utilising minimal electrical energy to transform plastics or biomass into **high-quality graphene** and **hydrogen gas**. These hydrogen gases can be transformed into clean compressed hydrogen ready for use in the market through UoM's Electrochemical H2 purification and compression process. **Storage**: With the lighter all-composite (Type-V) tanks yet to demonstrate the ability to remain impermeable at cryogenic conditions and the need of various sectors (e.g., aerospace) for lightweight solutions, HyPStore aspires to develop and commercialise an **impermeable cryogenic all-composite tank** for **liquid H2 storage**, by bringing together: * **GIM**'s **novel** **all-composite tank manufacturing process** combining dry filament winding with nanomaterial inclusion (graphene nanoplatelets). Multi-layered graphene has been demonstrated to **decrease hydrogen permeability by up to 48 times**, consequently forming a protective barrier and making the tank impermeable. * **FGR** will utilise the graphitic materials produced via the FJH process to manufacture a diverse array of graphene nanoplatelets tailored for optimal performance in CPV manufacturing by GIM. * **QMUL's** developed **self-healing systems** that fully or partially **treat matrix microcracks** created during the operation of the tank due to storing H2 at cryogenic conditions. * **BUL's** expertise in **LBB design features** in a prearranged design pattern, which under reaching certain loading conditions (e.g., over-pressurisation), will **act as stress concentration** points, creating a coalescing crack/leak path for the pressure relief of the tank and avoiding the catastrophic consequences of a burst. * **UniSQ's** great experience in fire-retardant coating combining high-fire retardance, good durability to resist aging and chemical erosion, high toughness to resist external impact, and low gas permeability. **Utilisation**: This market-driven project is supported by the participation of 2 aerospace industrial partners: (i) **Slingsby,** an aerospace Tier-1 supplier seeking to expand their commercial offerings by exploiting a pioneer all-composite tank and (ii) **HASL** (direct end-user/customer) who is keen to integrate HyPStore as LH2 fuel tanks onboard their hydrogen-driven High Altitude Platform capable of delivering ubiquitous high-bandwidth low-latency connectivity.

BT and Stratospheric Platforms Limited have come together with a vision of using an H2 HAPS platform to provide 5G cellular coverage over a wide area from a single aircraft. Used for both private groups, such as disaster first responders and security oriented teams over sea or land, or the general population the project will investigate advanced antenna technology capable of being packaged for use on a HAPS platform and proving the performance required to service large numbers of end users from HAPS high operational altitudes.
