Establishment of Austria’s First Regional Green Hydrogen Economy: WIVA P&G HyWest

The regional parliament of Tyrol in Austria adopted the climate, energy, and resources strategy “Tyrol 2050 energy autonomous” in 2014 with the aim to become climate neutral and energy autonomous. “Use of own resources before others do, or have to do” is the main principle within this long-term strategic approach, in which the “power on demand” process is a main building block and the “power-to-hydrogen” process covers the intrinsic lack of a long-term, large-scale storage of electricity. Within this long-term strategy, the national research and development (R&D) flagship project WIVA P&G HyWest (ongoing since 2018) aims at the establishment of the first sustainable, business-case-driven, regional, green hydrogen economy in central Europe. This project is mainly based on the logistic principle and is a result of synergies between three ongoing complementary implementation projects. Among these three projects, to date, the industrial research within “MPREIS Hydrogen” resulted in the first green hydrogen economy. One hydrogen truck is operational as of January 2023 in the region of Tyrol for food distribution and related monitoring studies have been initiated. To fulfil the logistic principle as the main outcome, another two complementary projects are currently being further implemented

Hydrogen in grid balancing: the european market potential for pressurized alkaline electrolyzers

Summarization: To limit the global temperature change to no more than 2 °C by reducing global emissions, the European Union (EU) set up a goal of a 20% improvement on energy efficiency, a 20% cut of greenhouse gas emissions, and a 20% share of energy from renewable sources by 2020 (10% share of renewable energy (RE), specifically in the transport sector). By 2030, the goal is a 27% improvement in energy efficiency, a 40% cut of greenhouse gas emissions, and a 27% share of RE. However, the integration of RE in energy system faces multiple challenges. The geographical distribution of energy supply changes significantly the availability of the primary energy source (wind, solar, water) and is the determining factor, rather than where the consumers are. This leads to an increasing demand to match supply and demand for power. Especially intermittent RE like wind and solar power face the issue of energy production unrelated to demand (issue of excess energy production beyond demand and/or grid capacity) and forecast errors leading to an increasing demand for grid services like balancing power. Megawatt electrolyzer units (beyond 3 MW) can provide a technical solution to convert large amounts of excess electricity into hydrogen for industrial applications, substitute for natural gas, or the decarbonization of the mobility sector. The demonstration of successful MW electrolyzer operation providing grid services under dynamic conditions as request by the grid can broaden the opportunities of new business models that demonstrate the profitability of an electrolyzer in these market conditions. The aim of this work is the demonstration of a technical solution utilizing Pressurized Alkaline Electrolyzer (PAE) technology for providing grid balancing services and harvesting Renewable Energy Sources (RES) under realistic circumstances. In order to identify any differences between local market and grid requirements, the work focused on a demonstration site located in Austria, deemed as a viable business case for the operation of a large-scale electrolyzer. The site is adapted to specific local conditions commonly found throughout Europe. To achieve this, this study uses a market-based solution that aims at providing value-adding services and cash inflows, stemming from the grid balancing services it provides. Moreover, the work assesses the viability of various business cases by analyzing (qualitatively and quantitatively) additional business models (in terms of business opportunities/energy source, potential grid service provision, and hydrogen demand) and analyzing the value and size of the markets developing recommendations for relevant stakeholder to decrease market barriers.Presented on: Energie
