Lyngby/Denmark – Topsoe has been selected to deliver its dynamic ammonia loop technology, as well as proprietary catalysts and equipment, for Synergen Green Energy’s ammonia project in the U.S. The first project, when operational, will be designed to produce 210,000 metric tons of ammonia annually and will avoid approximately 400,000 tons of CO₂ emissions - the equivalent of removing around 95,000 gasoline-powered passenger cars from the road for one year. The ammonia will be produced utilizing renewable electricity and used for the export market.

Henrik Rasmussen, Managing Director of Topsoe Americas, said: “We’re thrilled that Synergen selected Topsoe to collaborate on their impressive next generation ammonia projects. Green ammonia will add to the diversification of the fuel sources available to industry. We look forward to working with the talented team from Synergen.”

Synergen Green Energy CEO Pranav Tanti added: “Green fuels are the beginning of a new era for the world. We are excited to partner with a renowned company like Topsoe for their innovative synloop technology that adapts to intermittent power supply. This nascent industry needs partnerships to forge the way ahead and make green fuel projects economically viable, and green ammonia globally competitive. We, at Synergen, remain committed to this cause, and look forward to a long term and successful relationship with Topsoe.”

Ammonia – either in the form of an e-fuel (green ammonia) or in the form of low-carbon ammonia (blue ammonia) is expected to play a critical role in the energy transition. It can be transported using existing ammonia infrastructure; and it has multiple end-uses, not only as a fuel or hydrogen carrier but also to help decarbonize industrial processes like steel and cement production.

What is Topsoe’s dynamic ammonia technology

Topsoe’s dynamic ammonia technology adapts the production output of green ammonia in response to fluctuating supply of renewable electricity.

The dynamic ammonia process plant will enable:

The ramping up/down of the ammonia production bidirectionally at a rate of at least 3 % per minute in response to the fluctuating supply of hydrogen to the ammonia plant

Significant reduction in capital expenditure and operational expenditure since hydrogen storage systems can be reduced substantially, or otherwise eliminated

Renewable electricity to be stored in a zero-carbon chemical.
