The Green and Blue Ammonia Value Chain

As green and blue ammonia begin to be utilized as a zero-carbon marine fuel, we will see the need for substantial infrastructure development to support the demand. The green and blue ammonia value chains differ in the hydrogen production method used; green ammonia being generated from water electrolysis and blue ammonia being generated from a conventional pathway, using natural gas, but with the addition of carbon capture. The level of commercialization and the relative total installed costs for green and blue ammonia plants will be discussed.
