Today, we saw probably the single most important announcement in the five years that I've been tracking sustainable ammonia production technologies.
Global ag-input giant Bayer and MIT-spin off Ginkgo Bioworks ("we design custom microbes") announced a USD $100 million investment to engineer nitrogen-fixing bacteria into seed coatings, potentially displacing ammonia from its fertilizer market.
On the other side of the world, in the Philippines, researchers are developing another use for another bacteria: industrial-scale algal ammonia synthesis. This would allow ammonia to become a carbon-free biofuel, creating a new and much, much, much bigger market for ammonia: no longer fertilizer but energy.
