In Europe, green hydrogen and biogas/green gas are considered important renewable energy carriers, besides renewable electricity and heat. Still, incentives proceed slowly, and the feasibility of local green gas is questioned. A supply chain of decentralised green hydrogen production from locally generated electricity (PV or wind) and decentralised green gas production from locally collected biomass and biological power-to-methane technology was analysed and compared to a green hydrogen scenario. We developed a novel method for assessing local options. Meeting the heating demand of households was constrained by the current EU law (RED II) to reduce greenhouse gas (GHG) emissions by 80% relative to fossil (natural) gas. Levelised cost of energy (LCOE) analyses at 80% GHG emission savings indicate that locally produced green gas (LCOE = 24.0 €ct kWh−1) is more attractive for individual citizens than locally produced green hydrogen (LCOE = 43.5 €ct kWh−1). In case higher GHG emission savings are desired, both LCOEs go up. Data indicate an apparent mismatch between heat demand in winter and PV electricity generation in summer. Besides, at the current state of technology, local onshore wind turbines have less GHG emissions than PV panels. Wind turbines may therefore have advantages over PV fields despite the various concerns in society. Our study confirms that biomass availability in a dedicated region is a challenge.

The European Commission has selected the Northern Netherlands to become the leading European hydrogen region and supports establishment of a complete local (green) hydrogen ecosystem covering production, storage, distribution, refueling and final use of hydrogen (Cordis, H2Valley, 2019). In line with the European recognition, the Dutch government has set the goal to establish a hydrogen ecosystem by 2025 that would further expand to Western Europe by 2030. Yet before the European Union nominated the Northern Netherlands as European Hydrogen Valley, the key stakeholders in the Northern Netherlands – industry, SMEs, knowledge institutions and government – committed to the long-term cooperation in development of the green hydrogen market. Subsequently, the three regional governments of the Northern Netherlands, - Groningen, Friesland and Drenthe, - prepared the common Hydrogen Investment Agenda (2019), which was further elaborated in the common Hydrogen Investment Plan (2020). The latter includes investments amounting to over 9 billion euro, which is believed will secure some 66.000 existing jobs and help create between 25 thousands (in 2030) and 41 thousands (in 2050) new jobs.However, implementation of these ambitious plans to establish a hydrogen ecosystem of this scale will require not only investments into development of a new infrastructure or technological adaptation of present energy systems, e.g., pipelines, but also facilitation of economic transformation and securing the social support and acceptance. What are the prospects for the social support for the developing European Hydrogen Valley in the Northern Netherlands and its acceptance by inhabitants? The paper discusses the social support and acceptance aspects for a hydrogen ecosystem in the context of regional experiences of energy transition, including the concerns of energy justice, safety, and public trust that were raised in the recent past.

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
This Professional Doctorate (PD) research focuses on optimizing the intermittency of CO₂-free hydrogen production using Proton Exchange Membrane (PEM) and Anion Exchange Membrane (AEM) electrolysis. The project addresses challenges arising from fluctuating renewable energy inputs, which impact system efficiency, degradation, and overall cost-effectiveness. The study aims to develop innovative control strategies and system optimizations to mitigate efficiency losses and extend the electrolyzer lifespan. By integrating dynamic modeling, lab-scale testing at HAN University’s H2Lab, and real-world validation with industry partners (Fluidwell and HyET E-Trol), the project seeks to enhance electrolyzer performance under intermittent conditions. Key areas of investigation include minimizing start-up and shutdown losses, reducing degradation effects, and optimizing power allocation for improved economic viability. Beyond technological advancements, the research contributes to workforce development by integrating new knowledge into educational programs, bridging the gap between research, industry, and education. It supports the broader transition to a CO₂-free energy system by ensuring professionals are equipped with the necessary skills. Aligned with national and European sustainability goals, the project promotes decentralized hydrogen production and strengthens the link between academia and industry. Through a combination of theoretical modeling, experimental validation, and industrial collaboration, this research aims to lower the cost of green hydrogen and accelerate its large-scale adoption.
