The next step for green commercial shipping

Increasing concerns about sulphur emissions and water pollution has pushed the shipping industry to pursue a more sustainable method of transporting goods.

As climate change is one of the hottest topics today, businesses are becoming more conscious about their carbon footprint. The transport required for global trade is a specific concern.

A study published in Business Reporter points out that 90% of the world’s trade in goods is transported by ships. This means the shipping industry is responsible for around 14 per cent of the world’s sulphur emissions.

“The shipping industry is a lifeline of global trade,” says Hans Middelthon, Managing Director of Saudi Aramco Energy Ventures (SAEV) Europe Ltd, in the article. “However, shipping is a major pollutant contributing to climate change.” So what can be done to make a positive difference?

Daphne Technology, a green technology company based in Switzerland, has developed SulPure. Daphne was funded by SAEV, a company which focuses on providing sustainable energy. The SulPure process extracts nitrogen and sulphur oxide emissions from engine exhaust fumes by passing it through several stages:

  1. A pre-conditioning unit removes particulate matter, reducing carbon monoxide emissions by 99 per cent
  2. A purification unit then reduces sulphur emissions by 99.3 per cent and nitrogen emissions by 85 per cent
  3. The nitrogen extracted from the process is released harmlessly into the atmosphere
  4. The sulphur is collected and made into ammonium sulphate – which can be used as an agricultural fertiliser

Mario Michan, CEO at Daphne Technology, puts it like this: “Ship owners really care about sustainability and we offer a full closed-loop solution which adheres to IMO 2020, and is financially attractive.” Indeed, there are ways to combat the challenges faced by ship traders without cost to the environment.

Shipping is responsible for 18% of the world’s air emissions, with the current technology, it is possible to cut out these emissions almost entirely. However oil spillages, habitat destruction from collision and the overall sound pollution from shipping is killing a great number of marine life.
