Green hydrogen technologies play a pivotal role in the transition toward low-carbon industrial solutions. The gH2ADDVA project focuses on developing clean, environmentally friendly energy production methods, novel material technologies, and AI-based tools for value chain modeling. The project strengthens Finland’s energy self-sufficiency and industrial networks while addressing rising energy costs. The main objectives include: (1) Efficient electrolysis and bio-based hydrogen production, storage, and utilization methods; (2) Advanced material solutions for renewable energy and hydrogen storage; (3) AI-driven approaches for digital twins and value chain optimization; (4) Regional RDI and industrial collaboration in hydrogen technologies. The research combines techno-economic analyses, laboratory testing, and computational modeling. Key results include: – Preliminary studies on biomass-based hydrogen production and its economic feasibility; – Development of new material and surface technologies for hydrogen storage, including ALD coatings and fatigue-resistance testing; – Optimization of electrolytic surfaces and sensor systems for safe hydrogen use; – Digital implementation of hydrogen value chains using AI methods such as semantic analysis, LLMs, and Retrieval-Augmented Generation. These findings contribute to cost-effective and safe hydrogen integration in industrial processes, supporting SMEs in Central Finland and reinforcing the region’s position in national and EU-level hydrogen clusters. The project demonstrates how multidisciplinary research—spanning physics, bioeconomy, and computational sciences—can accelerate the adoption of green hydrogen technologies and foster sustainable industrial renewal.
