New circular economy project: Wind power to be stored as green ammonia

By State of Green, August 21, 2018

The circular economy entails reusing and reutilising resources. A new pilot plant is to be established that will store surplus energy from wind turbines and transform it into a sustainable, green ammonia product. Doing so will also help reduce CO2 emissions.

GreenLab Skive, which is a business park in the Danish town of Skive that works actively with integrated renewable energy, energy storage and resource efficiency and wind energy giant, Siemens Gamesa Renewable Energy, have entered into a partnership to construct a test plant that will convert wind power to ammonia.

For Siemens Gamesa, the production of green ammonia is a way to store energy from both on- and offshore wind turbines.

”Storage and conversion of energy and resources is one of the biggest challenges facing the future’s green and sustainable energy supply. One of the solutions can be the utilization of surplus energy from wind turbines to produce green ammonia. This is a win-win solution, as it utilises the surplus power that is produced in windy periods and we also create a new sustainable product; green ammonia,” says Siemens Gamesa’s senior key expert, Jens Schiersing.

Fossil fuels are used in the production of conventional ammonia. Given that ammonia production is energy intensive, producing green ammonia would result in considerable reductions in CO2 emissions. Ammonia is a multi-purpose product, but is a particularly important input in artifical fertilisers that are used for agricultural purposes. Together, Siemens Gamesa and Skive Energy Foundation (which is the business foundation behind GreenLab Skive) will explore the optimal way to construct the pilot plant that will produce green ammonia in Skive over the next few years. Currently, activities are focusing on clarifying the size and production capacity of the test facility.

“We’re looking very much forward to the collaboration, which is taking action on one of the biggest challenges in our energy system in regards to surplus energy and storage,” says GreenLab Skive’s commercial direction, Christopher Sørensen.

”It will also be a solution that can become a part of our industrial symbiosis and our shared, internal network that exchanges energy and resources. Ammonia plays an important role in agriculture, but there is also potential to use it as a fuel source for internal combustion engines,” he continues.

The establishment of the pilot plant will be a central element in GreenLab Skive and the centre for energy integration and storage. Furthermore, GreenLab Skive and the Technical University of Denmark are working on the establishment of a national centre, where GreenLab Skive will also play a leading role.
