US House draft bill defines ammonia as low-carbon fuel
Article

In January 2020, the US House of Representatives published draft legislation that explicitly defines ammonia as a "low-carbon fuel." This is a first. The CLEAN Future Act is focused on electricity generation, and aims "to build a clean and prosperous future by addressing the climate crisis, protecting the health and welfare of all Americans, and putting the Nation on the path to a net-zero greenhouse gas economy by 2050." The point isn't that this will become law — that seems unlikely anytime soon — but that a mature understanding of the potential benefits of ammonia energy has finally reached policymakers in the heart of Washington DC.

Maritime decarbonization is a trillion dollar opportunity
Article

In January 2020, the Global Maritime Forum published new analysis that calculates "the capital investment needed to achieve decarbonization" in line with the International Maritime Organization's Initial GHG Strategy. The result of this analysis, which assumes that ammonia will be "the primary zero carbon fuel choice adopted by the shipping industry," is an aggregate investment of between $1 trillion and $1.4 trillion dollars, from 2030 to 2050, or roughly $50 to $70 billion per year across two decades. Ship-side costs are only 13% of this number. The bulk of the investment will be directed towards green ammonia plants for maritime fuel synthesis. By 2050, this global fuel demand is estimated to be more than 900 million tons per year of green ammonia, more than five time today's total global output of conventional ammonia.

MAN ammonia engine update
Article

In November 2019, MAN ES published a technical paper describing the design and performance of its two-stroke green-ammonia engine. The paper also quietly announces the intentions of MAN ES to exploit ammonia energy technologies in a new business case, Power-to-X (PtX, "the carbon-neutral energy storage and sector coupling technology of the future"). In other words, MAN is moving into green ammonia fuel production.
