Bad Lauchstädt Energy Park

By ONTRAS (Germany)

Technical aspects

• Windpark: 40MW – Electrolyser: 35 MW – Gas pipeline: 100,000 m³/h
• Storage capacity: 50 million m³ ≈ 150 million KWh ≈ households heating annual demand for in a city of 20,000 residents[1]. The energy park is expected to produce 24 million m³/a H₂[2].
• Objectives: By 2025, substitution of 1.3 billion m³ with H₂ (CO₂ savings: 1.3 million tonnes). By 2050, substitution of 9 billion m³ with H₂ (CO₂ savings: 9 million tonnes). It will be used for the Chemical industry and urban usage: local heating, mobility (development of a H₂ filling station directly connected to the H₂ network).

Contribution to energy transition

Green H₂ produced from renewable electricity using electrolysis is non-polluting and easy to store. It enables to compensate for weather-related fluctuations in solar/wind power generation and provides for efficient sector coupling. It will contribute to decarbonise mobility and industry sectors and will help promote large scale hydrogen projects. The project will boost research and accelerate market maturity of innovative H₂ technologies: it will serve to test under real-world conditions and at an industrial scale. On the long-term, it will contribute to expend at large-scale the integration of green H₂ in central Germany, and sector coupling technologies throughout the country and via EU.
