Siemens Gamesa partners up on green ammonia production
Renewable energy giant Siemens Gamesa has signed an agreement with an environmental group to look into the clean production of ammonia for energy storage.
In partnership with Denmark’s Energifonden Skive, the company will look to find an eco-friendly way of using ammonia to store surplus energy from wind turbines.
Ammonia, which is converted from nitrogen gas and then back into nitrates in soil as part of the natural nitrogen cycle, is traditionally produced using fossil fuels, with high emissions created as a result. The end project is often used in fertilisers or fuel for combustion engines, but also has further energy storage potential.
The research and development is to take place at the GreenLab Skive site in Denmark, with the size of the potential green ammonia facility yet to be outlined.
Jens Schiersing Thomsen, senior expert at Siemens Gamesa, stated: “In the green, sustainable energy supply chain, one of our biggest challenges will be storing and converting energy and resources.
“One solution may be the use of surplus wind-based electricity to produce eco-friendly ammonia. This solution would offer double benefit: using the surplus energy that arises in peak wind situations, and creating a new sustainable product we call green ammonia.”
Drax advances biomass strategy with Pinnacle acquisition
The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.
The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).
This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.
In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.
The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
