Exploring Sustainable Energy Solutions in Hattingen: A Look into the Future
The city of Hattingen, Germany, is paving the way towards a sustainable future, targeting a climate-neutral heating supply by 2045. Their local utility company, Stadtwerke Hattingen, along with the Gas and Heat Institute of Essen (GWI), is exploring a variety of renewable sources, including geothermal, solar thermal energy, river heat, and wind power.
The Power of Geothermal Energy
Geothermal energy is a promising resource for Hattingen. The State Office for Nature, Environment and Consumer Protection (LANUV) conducted a comprehensive study revealing that geothermal sources could potentially meet the city’s entire heating demand. Geothermal energy is being considered at various depths, ranging from near-surface to up to 1000 meters.
However, Stefan Kuchner, project manager at Hattingen’s municipal utilities, highlights that the effective utilization of geothermal energy requires a high connection density, suggesting on-site use. Identifying suitable locations for geothermal drilling is now a focal point in their strategic planning process.
Diversifying Energy Sources
The utility company hasn’t stopped at geothermal energy. They are also evaluating solar thermal energy, river heat, and the potential of mine water from the former Friedlicher Nachbar mine. River heat, for instance, boasts a potential output of 20 MWth, beneficial for consumers along the Ruhr River.
When it comes to renewable electricity, the analysis shows existing potential with photovoltaics generating around 13.6 GWh and wind power contributing 4.1 GWh. With a significant photovoltaic potential of approximately 150 GWh, growth is expected, although considerations for fluctuating supply patterns remain.
Strategizing for Climate-Neutral Heat Supply
The findings from these potential analyses have provided a foundation for Hattingen’s concrete target scenarios. With the dedication of the Stadtwerke Hattingen and GWI, strategies for systematically transitioning to a climate-neutral heat supply are being developed.
