According to the International Civil Aviation Organization, the world aviation air traffic has grown by an average yearly rate of 5% over the last thirty years, until the devastating downturn brought on by the COVID crisis of 2020. Regardless of the current situation, there are still a number of issues and challenges that the industry is confronted with, not the least of which are related to sustainability, the conversion to electrical usage, the challenge of increasing propulsion efficiency in conventional propulsion, the digital transformation of the entire ecosystem, etc. In response, system developers and researchers in the field are working on a number of key technologies and methodologies to solve some of these issues. The Sustainable Aviation Research Society (SARES), a global organization that seeks to encourage research in this area and helps disseminate knowledge via conferences and symposia, has been organizing meetings to promote sustainable aviation over the five years. Three of these are the International Symposium on Sustainable Aviation (ISSA), International Symposium on Electric Aviation and Autonomous Systems (ISEAS), and the International Symposium on Aircraft Technology, MRO, and Operations (ISATECH).
This report consists of two parts and describes the highlights of the investigations carried out in the Province of Groningen as part of the Right Project to understand the Regional Innovation Ecosystem in the region. The first part is focusses on the socio-economic and R&D profile (Part 1A) and a SWOT analysis on salient aspects related to Regional Innovation Ecosystems (Part 1B). The second part (Part 2) focuses on the SME innovation capacity and needs, and presents the highlights of 6 interviews with SMEs in the region. The RIGHT project, an Interreg North Sea Program, will contribute to territorial growth in the North Sea Region by connecting smart specialisation strategies to human capital and the skills of the workforce by defining existing and potential regional growth sectors and sub-sectors.

Wind and solar power generation will continue to grow in the energy supply of the future, but its inherent variability (intermittency) requires appropriate energy systems for storing and using power. Storage of possibly temporary excess of power as methane from hydrogen gas and carbon dioxide is a promising option. With electrolysis hydrogen gas can be generated from (renewable) power. The combination of such hydrogen with carbon dioxide results in the energy carrier methane that can be handled well and may may serve as carbon feedstock of the future. Biogas from biomass delivers both methane and carbon dioxide. Anaerobic microorganisms can make additional methane from hydrogen and carbon dioxide in a biomethanation process that compares favourably with its chemical counterpart. Biomethanation for renewable power storage and use makes appropriate use of the existing infrastructure and knowledge base for natural gas. Addition of hydrogen to a dedicated biogas reactor after fermentation optimizes the biomethanation conditions and gives maximum flexibility. The low water solubility of hydrogen gas limits the methane production rate. The use of hollow fibers, nano-bubbles or better-tailored methane-forming microorganisms may overcome this bottleneck. Analyses of patent applications on biomethanation suggest a lot of freedom to operate. Assessment of biomethanation for economic feasibility and environmental value is extremely challenging and will require future data and experiences. Currently biomethanation is not yet economically feasible, but this may be different in the energy systems of the near future.
Green Hydra main scope is to improve policies from 10 regions of different types and levels - national, regional or local - to establish support initiatives and measures for opening the access of SMEs to green H2 development projects, from research programmes to development strategies, awareness-raising schemes, and pilot investments especially focused on involvement of SMEs across the whole hydrogen value chain, including R&D, engineering, manufacturing, consultancy, human resources upskilling and design.The specifc objectives are:- probing the conditions for using green H2 in the key sectors involving SMEs- identifying the potential key factors to activate the involvement of SMEs around the green H2 value chain- supporting for the creation of a production chain involving SMEs- developing new skills, knowledge and communication for green H2 for SMEs- easing SMEs access to fi nance in the fi eld of green H2- upscaling innovations for SMEs related to green H2 products and services
