The Advanced Research in Control of Hydrogen-Electric Engines (ARCHEE) project, led by ZeroAvia in partnership with the University of Bath, will develop the advanced control technologies needed to enable safe, certifiable hydrogen-electric aircraft. Hydrogen fuel cells are a key solution for zero-emission aviation, but current control systems are not yet capable of meeting the performance and safety standards required for commercial flight. ARCHEE will address this by creating a new engine control system that manages fuel cell performance, monitors high-voltage systems, and ensures safe operation under all conditions. Over 18 months, the project will build and test a prototype system using ZeroAvia's ZA600 hydrogen-electric engine as a foundation. This work will help accelerate the certification and commercial deployment of hydrogen-electric aircraft, starting with retrofits of subregional aircraft like the Cessna Caravan. ARCHEE will also strengthen the UK's position in clean aviation by developing domestic expertise and supply chains for fuel cell engine controllers. The project is expected to create green jobs and unlock over £400 million in future investment. By enabling widespread use of hydrogen-electric propulsion, ARCHEE could help cut more than 6 million tonnes of CO₂ equivalent emissions by 2037 through the first product application alone, significantly reduce noise pollution at airports, and remove air pollutants such as NOX and PM entirely.

The **Greater Manchester Electro-Chemical Hydrogen Cluster (GMEHC) phase 2 project** builds on GMEHC phase 1's aim to create an ecosystem to facilitate accelerated innovation and an investible business case. It will bring together areas of regional expertise to support innovation, enhance Greater Manchester's and the UK's capability in electrochemical hydrogen technologies to drive advancements in renewable energy and support the decarbonisation ambitions of Greater Manchester. The objectives are to: • Advance hydrogen technologies through intensive R&D activities. • Create a regionally based but nationally focused coherent innovation ecosystem with all elements of the value chain that will provide the link between innovation and economic growth, drawing lessons from international comparators. • Leverage and organise a minimum of 1:1 ratio of private sector co-investment against the project funding level. • Build capacity in Greater Manchester SMEs to get them innovation ready and able to commercialise technology developed through R&D programmes. GMEHC phase 2 project scope will continue to be delivered across three distinct strands of delivery. These are: 1.Technical research and development GMEHC phase 2 will continue to deliver and extend four 'testbed' R&D projects with key industry partners through more detailed and extensive R&D activity, and increase the opportunity for new products and services. SMEs will also be supported to develop the technology readiness of their products and thereby increasing the capacity of the GM Innovation Ecosystem. 2.Innovation capacity building This will focus on a new industry partnership with Bosch, specifically their PEM Electrolyser Fuel Cell Stack. Delivered through cohorts of knowledge exchange workshops, the aim is to support SMEs to understand the opportunity, building the local supply chain and manufacturing capability, and become systems integrators for Bosch. 3.Enhancing regional capability Strand 3 will build on the business case developed in phase 1 including the design, location and options to create a new National Centre for industrialisation of fuel cells and electrolysers, based in Manchester. It will deliver an Electrochemical Hydrogen Technologies Economic Review and model a data-led review of the enhanced capabilities identified in the Phase 1 reports of GMEHC. This will feed into and create a "foundational hydrogen economy and capability matrix" for Greater Manchester.

The LH-SIFT project will deliver a flying platform to **enable rapid iteration** and testing in the maturation of cryogenic fuel systems for zero-emission aviation using liquid hydrogen as a fuel. Liquid hydrogen is a **critical technology for scaling zero-emission** **propulsion** for the multi-billion dollar worldwide regional and international aviation market. Today, the global industry has limited experience with these technologies' functional performance in real aviation environments. While LHMS (Liquid Hydrogen Management Systems) have been flown in European testbed aircraft, the **UK lacks equivalent experience and capability in this area**. Systems need to be prototyped and tested not only in labs, but in the aircraft environment. Tackling these issues is critical to informing the direction of technology development, technical regulations, ground operations and refuelling safety requirements, procedures and **early securing of IP in the UK supply chain.** This project will prototype a scalable LHMS, ground test the system, install it on the proposed test platform aircraft and flight test the system and its technology bricks, thus **creating a UK LHMS flight test platform in an existing commercial airframe**. Utilising a Dornier 228 aircraft with one engine converted to hydrogen electric propulsion (ZA600) will provide a **low-cost, efficient and flexible means of testing and maturing LH2 storage** and distribution technology bricks for aviation, putting the UK in the lead for development of commercially relevant aviation LHMS This testbed will then be configured to **provide a flexible and safe environment for installation of a wider variety of LHMS and underlying components**, in collaboration with partners Reaction Engines. GRE, and Gas and Liquid Controls, providing unparalleled knowledge and **UK competitive advantage** around alternative tank technologies and emerging concepts. LH-SIFT will **accelerate technology maturity** of aerospace LHMS and the UK supply chain; **deliver additional high-value, green jobs in the UK**; demonstrate capability with a series of high-profile UK liquid hydrogen flight-tests; deliver **creation and adoption of new ways of working with liquid hydrogen via work with the CAA; and attract global innovators and further investment into the UK.**

The AFCAD (Advanced Fuel Cells for Aviation Decarbonisation) Project will deliver a critical technology for scaling zero-emission propulsion for the multi billion dollar global regional aviation market. Through the advancement of high temperature polymer electrolyte membrane (HTPEM) fuel cell technology, the project will enable zero-emission propulsion for regional aircraft (turboprops and jets) up to 90 seats. Supporting the ATI's Destination Zero/Fly Zero Strategies, and the Government's Jet Zero Strategy, AFCAD can also provide the foundations for clean propulsion systems for narrowbody aircraft, a massive potential market and significant contribution to tackling climate change. Low Temperature PEM (LTPEM) fuel cell systems have been proven in flight for 20 seat aircraft via the ATI HyFlyer II Project led by ZeroAvia and identified as one of the Jet Zero Strategy's six major achievements to date. However, for larger aircraft it is necessary to improve the energy-to-weight ratio of the fuel cell systems, which necessitates moving to higher temperature fuel cells. AFCAD will focus on research, build, test and evaluation of HTPEM stack technologies (bipolar plates (BPP), membrane electrode assembly (MEA)) and their integration into a stack, with four main metrics being improved: Power Output, Specific Power, Efficiency and Durability. These technologies will be taken from TRL 3 to TRL 5 by sophisticated test campaigns of components and systems in collaboration with the University of Coventry and University of Kent, while the University of Sheffield's Advanced Manufacturing Research Centre (AMRC) will collaborate on manufacturability and supply chain development, preparing the ground for this technology to be rapidly integrated into the UK's advanced manufacturing base. AFCAD can catalyse UK global leadership for zero-emission flight technology and advanced fuel cell development, helping to realise the vision of the UK as a Science Superpower and centre for green advanced manufacturing.

ZeroAvia, the market leader pioneering the development of hydrogen-electric powertrains, and partners Wessington Cryogenics-LUX Industries and University of Southampton, will collaborate on Project LHMSD (Liquid Hydrogen Mobile Storage and Dispensing). The project will focus on multiple Hydrogen deliverables, each at varying technology readiness levels accelerating the consortium partners further towards commercialisation. As part of these developments, the associated infrastructure for Liquid Hydrogen will be engineered and addressed, via an integrated, affordable ecosystem which can most effectively be implemented with partnerships and collaborations. LUX seeks to increase supply capacity and lower the cost of Liquid Hydrogen, requiring partnerships to accelerate the UK's transition to a Hydrogen future. Wessington wishes to expand its product range, with the associated commercial opportunities this brings. In partnership with University of Southampton, the consortium will conduct economic modelling of Hydrogen infrastructure and supply chains, in addition to predicting costs of Hydrogen from present day to 2050 Net Zero targets.

To accelerate the development of hydrogen-electric aircraft powertrains. This KTP will address aerodynamic integration challenges for hydrogen fuel cells to deliver zero emissions commercial aircraft powertrains capable of carrying up to 20 passengers by 2024 and 90 passengers by 2026\.

The Future Flight Project, is a collaboration between the Institute for Research in Schools (IRIS) and ZeroAvia which gives students across the UK an opportunity to learn about Carbon Net-Zero aviation through developing their research, teamworking, problem solving skills and knowledge. This project directs students to carry out initial, individual research to discover the current impact that commercial aviation is having on the planet and how carbon emissions can be reduced. Students will learn the theory behind hydrogen fuel cells and hydrogen aircraft alongside the basic fundamentals of aircraft design and operation. The students will conduct Initial research and then develop innovative solutions to adapt an existing aircraft to accommodate hydrogen tanks for carbon-free flight; they will use OpenVSP (free software developed by NASA) to model their aircraft adaptations and virtually test their aircraft to gauge its performance. This project will test students' ability to interpret data from software, make conscious design decisions and give them experience working towards a real life challenge faced by ZeroAvia's technical teams. Students will have to consider the impact of external vs. internal tanks by various means of cost benefit analysis including drag, ticket price and range. The project will develop students' holistic thought processes when making decisions to achieve aircraft adaptations that minimise environmental impact and consumer cost. Participants will be able to complete the project alone and discuss OpenVSP results, concepts and ideas amongst classmates to allow collaboration and peer support. The students will finalize their projects via a poster to document their research and stretch tasks also include the opportunity for students to 3D print their aircraft design models. The project will include regular webinars and face to face visits with the technical team at ZeroAvia and culminates in an IRIS conference, where students have the opportunity to present their research and results to other students interested in STEM from all over the UK.

ZeroAvia, the market leader pioneering the development of hydrogen-electric powertrains, and Filton Systems Engineering, market leader pioneering the development, testing and certification of liquid hydrogen fuel-systems for civil aviation, will work together on Project LIHFE-10\. The project will combine the capabilities of both Organizations to develop and demonstrate a 300kW hydrogen-electric powertrain running on liquid hydrogen in ground test facilities. The project will prove out a number of technical challenges around handling, storing and conditioning hydrogen at cryogenic temperatures; and will deliver a composite tank with an increased capacity of 10kg. Upon successful completion of this ground based demonstrator project the system architecture will be designed ready for a follow-on project to develop into a flight-testable system. The team's aim is to demonstrate the extended range and efficiency offered by the significant improvement in energy storage when transitioning from gaseous hydrogen to liquid hydrogen. The system will subsequently be scaled for different aircraft types and customer's operational requirements.

GMECH will deliver an Innovation Accelerator for hydrogen technologies. It has 2 strands (1) technical innovation, in relation to the materials challenges & measurement challenges for Fuel Cells and Electrolysers and (2) SME capacity building through Business Model and Product Innovation activity The GMECH Cluster will form a critical element of a wider innovation eco-system with all elements of the value chain, building upon existing strengths in Greater Manchester and the Manchester Fuel Cell innovation Centre, the University of Manchester, Henry Royce Institute, and the National Physical Laboratories (NPL). This will form a vital part of a national hydrogen development programme, accelerating the development and adoption of clean, efficient electrochemical hydrogen technologies and put Greater Manchester at the core of internationally leading R&D, the creation of highly skilled jobs, and drive inward investment.

Use cases will include: * Scheduled airline routes * Offshore energy services * National Health Service activities * Island / remote region deliveries * Environmental survey and inspection Implementation of these will require advances in technology, regulation, and policy. These are reflected in the cross-cutting activities which include: * Establishing a dedicated test environment airspace * Matchmaking technology to community and business needs * Accelerating technology innovation * Mapping out the future Highlands and Islands aviation system Kirkwall Airport is one of eleven airports operated by HIAL and an ideal test environment location due to the variety of operated routes (including short hops to inter-island airfields operated by Orkney Islands Council). The wider project team includes leading technology developers ZeroAvia, Windracers and FlareBright. EMEC brings expertise in green-hydrogen refuelling infrastructure, and HITRANS will lead on connectivity into the wider transport system. The socio-economic impact of a new regional-aviation system will be supported by UHI, Connected Places Catapult (CPC) and Aracadis. This project will also stimulate inward investment and supply chain growth which is a key responsibility for Highlands and Islands Enterprise (HIE). Project highlights will include working with the CAA to approve a regional sandbox airspace, establishment of a UAV hub-and-spoke delivery network, a first hydrogen-propelled regional-aircraft flight and an international demonstration flight to Norway.

HEART (Hydrogen- Electric and Automated Regional Transportation) is a programme that will demonstrate a viable regional transport network that is zero carbon, affordable, scalable and safe. It is aimed at sub-regional aviation (typically using 9-19 passenger aircraft, with circa 100 licensed airfields around the UK) with an objective to enable a commercially viable, innovative and eco-friendly network that provides a passenger experience giving door-to-door travel options, improved convenience, flexibility and travel information along with visibility of carbon footprint. The HEART programme will create a compound demonstration and vision of a 'Day-in-the-life' of a deployed network, culminating in flight trials utilising aircraft with hydrogen-electric powertrain, autonomous pilot control and support systems, as well as other key technologies that better account for the needs of travellers and support them throughout their journey. The HEART programme will address the following key areas: * Aircraft with hydrogen fuel cell and electric powertrains and on-board automation in order to significantly reduce cost of operations and help improve operational reliability. * Implementation of green hydrogen infrastructure (production storage and refuelling) with consideration of transport and distribution solutions, along with developing a skilled workforce to operate and maintain the infrastructure and aircraft. * Use of aircraft control automation, including pilot assistance pilot during high workload; enabling higher operational safety and scalability. * Use of hybrid connectivity solutions to assist in datalink operation, mission critical communication, as well as providing in-cabin passenger services. * Integration of the HEART network with other transportation modes through mobility-as-a-services solutions to enable fast transfers across new and legacy transport modes. Dynamic in-journey support to simplify and smooth the travel experience. * Use of autonomous ground systems to 'guide' aircraft, automate baggage and cargo loading/unloading and handle refuelling operations, increasing operational safety, reducing operating costs and enabling scale-up of operations. * New, low-cost, modular and scalable airport terminal technology concepts brought to life through simulation, modelling and technical demonstrations to demonstrate enhanced passenger experience. * Understanding and addressing societal concerns such as safety of hydrogen-electric powertrains, dependence on new levels of automation and technologies. These facets of demonstration, simulation and analysis will be brought together in a compound narrative called the 'HEART Mosaic' to show the full 'Day in the Life' picture of the network operation, which will be published through various media and engagement methods to show the journey HEART has taken, and how it will develop to serve people in the future.

With hydrogen-electric aviation as the only credible large-scale zero-carbon aviation option, the HyFlyer II project aims to take huge steps towards accelerating its adoption. It will repower an existing sub-regional airframe with a certifiable 600kW powertrain developed by ZeroAvia, integrating Aeristech's unique air compression technology. To complete the ecosystem, EMEC will provide green hydrogen and design the operational systems for fuelling at commercial airports. In setting up a unique UK supply chain, it positions the country's aviation industry for the next century of aviation - demonstrated by a 300NM zero-carbon flight of a 19-passenger aircraft at the end.

The consortium's vision for _HEART_ (**_H_**_ydrogen**-**_ **_E_**lectric and **_A_**utomated **_R_**egional **_T_**ransportation) is to develop a sub-regional air transportation network that is _zero carbon_, _affordable_, _scalable_ and _safer_ and with a targeted entry into service in 2025\. Consortium partners include: Blue Bear, ZeroAvia, Loganair, HIAL, Britten-Norman, Inmarsat, Protium, Weston Williamson + Partners, Fleet-on-demand and Edinburgh Napier University. Project HEART is aimed at sub-regional aviation (9-19 PAX aircraft, <500NM). Today's operations are economically uncompetitive due to the high operating costs of the aircraft relative to the number of seats and labour-intensive ground operations amongst other factors. By introducing state-of-the-art technology and infrastructure, the consortium will unlock a sub-regional air travel market that will avoid major congested airports and instead utilise the \>100 licensed airfields around the UK. Passengers can then experience shorter door-to-door travel times, cheaper ticket prices, and a zero-carbon travel option. The key enablers that the HEART consortium will develop during the Future Flight Challenge to unlock this market are: * Novel aircraft with hydrogen fuel cell powertrains and on-board automation (to reduce pilot workload and enable remote support) that will significantly reduce marginal cost of operations. * Green hydrogen infrastructure (production, storage, handling and refuelling) to support and sustain full scale operations together with a skilled workforce to operate and maintain this infrastructure and aircraft. * Single (not two) pilot operations through use of next generation digital towers and remote co-piloting stations to assist pilots during high workload situations which, in turn, enable higher operational safety and scalability within a high-volume network. * Use of a hybrid connectivity solution which combines high bandwidth terrestrial networks (3G/5G) with high-reliability satellite communications to support remote co-piloting and mission critical communication in the cockpit, as well as additional revenue streams from in-cabin use. * Use of autonomous ground robots to 'guide' aircraft, automate baggage loading/unloading and handle refuelling operations. This will increase operational safety, reduce operating costs and enable scale-up of operations. * Radical new aircraft terminal designs that are low-cost, modular and scalable. These terminals will ensure quick intermodal transfers for passengers and automated infrastructure. * Integration of the HEART network with other transportation modes through mobility-as-a-services solutions to enable fast intermodal transfers, door-to-door journeys and 'just-in-time' operator models. Other modes to include existing first/last mile options such as buses and taxis and future solutions such as eVTOLs. * Addressing social acceptance issues such as 'perceived safety of hydrogen powertrains', 'remote co-pilot operations' and understanding the various levers that will affect public perception of these technologies. In Phase 2, the consortium will undertake various proof-of-concept demonstrations to work towards a certifiable commercial demonstration at the end of Phase 3\. The two phases of the Future Flight Challenge project will fast track market readiness by 2025 and full deployment in the UK between 2025 and 2030\.

This Orkney Island -based, innovative project will create the UK's first low-carbon aviation test environment, based at a licenced island airport with all year round scheduled air service operations to UK, and regular off-shore oil and gas helicopter traffic. The Sustainable Aviation Test Environment (SATE) will be a UK first and, should one or more of the new aviation technologies be adopted for island use, it will also help improve the quality of life of the communities it serves (through job creation, improved access to education and healthcare, etc.). The SATE will place the UK at the vanguard of the adoption of next-generation aircraft, and spearheading aviation's response to climate change. The continued demand for aviation services (air passenger numbers on the 11 HIAL airport network have increased by 33% in the last 10 years) , is at odds with the effects of an international climate emergency. We need to rapidly decarbonise the aviation sector to reconcile these competing imperatives and to reduce the carbon footprint of air travellers. Indeed, if aviation is to be used as a means to improve the quality of life and maintain or grow the population of remote and rural communities, then the options for the appropriate sustainable aviation technologies must be explored. The options include the following: * aircraft (with electric, hydrogen, or synthetic fuel replacing conventional fossil fuels), * changes to the physical airport infrastructure to support the adopted technologies, and transport to the airport * green energy supply for terminal buildings and ground operations, * necessary digital networks for resilient communication between airport and aircraft (particularly UAVs). Kirkwall Airport is one of an 11-airport, regional airport group, operated by **HIAL** - who are project lead -, and is particularly suited as a test environment location due to the variety of routes it offers which include: short hops to the inter- islands airfields, eg Westray - best known for being one of the two airports joined by the shortest scheduled flight in the world -, and operated by **Orkney Island Council.** In addition there are regular air services to Aberdeen, Edinburgh & Glasgow, with a summer service to Norway. The project team includes technology developers who will be test ready during the 18 months of this project phase: **Ampaire**, **ZeroAvia**, **Windracers**, **Flarebright** and **Loganair**. Orkney provides options to fly over water, in a challenging environment & climate, for real-world application testing of the technologies. Decarbonisation of the airport, as part of this project, is important to the Orkney community, which is an exemplar early-adopter for other low-carbon technology, and are leaders in decarbonisation, lead by one of the SATE project members, Orkney-based **EMEC**. This test environment offers a number of integrated energy-system opportunities providing significant wider impacts for potential adoption at other regional airports, which is a focus of team member **HITRANS**. The supply chain and future business opportunity interests are represented by Caithness-based battery manufacturers - **Denchi Group** and Orkney-based **Cloudnet ,**specialists in providing digital services for poorly served rural communities. The people skills necessary to support the development, testing and maintenance of the new technologies are of interest to project team members - **Air Training Services** and the **UHI**. If successful, this project should stimulate inward investment and local supply chain business opportunities in this remote part of the UK, a key responsibility for **Highlands & Islands Enterprise.** Local community acceptance of new aircraft technology, especially on lifeline services, and the potential impact on their local economy and wellbeing will also be measured, and a local community engagement programme is key to this projects success.

ZeroAvia is developing a hydrogen fuel cell powertrain for light aircraft and plan to demonstrate principal technology readiness by mid-2020, by flying a 6-seater plane 300 nautical miles, equivalent to London-Edinburgh. The commercial market entry will be with a sub-regional aircraft with increased range in 2022, providing a zero-emission and 50%-cheaper alternative. The project brings together a unique group of innovative UK organisations with the aim of enabling a potentially transformational shift to zero-emission aviation, whilst reducing road and rail congestion, cutting air pollution and noise, supporting regional regeneration and creating greater choice and convenience for consumers.
