Challenge

Green ammonia represents a crucial medium for energy storage, enabling the integration of renewable energy in hard-to-electrify sectors such as shipping, which roughly accounts for three percent of global energy-related CO2 emissions (European Commission, 2018). Topsoe, Vestas and Skovgaard Invest have joined forces in the REDDAP-project, which aims to realise the potential of green ammonia as a cost-effective, versatile and high-energy-density green fuel capable of being produced at industrial scale.

Solution

REDDAP, short for Renewable Dynamic Distributed Ammonia Plant, seeks to create the world’s first dynamic green ammonia plant at a commercial scale of 10 MW in Lemvig, Western Jutland. Renewable energy from a connected 12 MW onshore wind farm and a 50 MW solar plant will drive the Power-to-X plant, producing hydrogen which will then be converted into ammonia. This dynamic approach connects wind and solar energy directly to the Power-to-X facility, making it more cost-effective by eliminating the need for battery or hydrogen storage, due to the plant’s ability to operate at loads ranging from five to 100 percent. Surplus renewable energy will be fed into the national grid, thereby contributing to sector coupling.

Result

The plant, expected to be operational by the end of 2024, will produce over 5,000 tonnes of green ammonia annually, preventing 8,200 tonnes of CO2 emissions each year.
