“Ammonia is only a liquid in a tank,” he mentioned, requiring no wires or circumstances that batteries require.
Market potential
Tim Krebs, Aza Power’s chief monetary officer, serves on the boards of different ammonia startups and comes from an oil and gasoline background. After lithium ion and hydrogen, ammonia will turn into “the subsequent complement for decarbonizing the world and as a solution to transfer hydrogen across the planet,” Krebs mentioned.
He lists off the potential market: offroad tractors, mining gear, bulldozers, locomotives, mining gear, tractors, backhoes, and maritime fleets, particularly ferries and tugboats. These sorts of engines may be transformed to burn ammonia with out nice expense, he mentioned.
Quite a lot of market stories can be found on the expansion of inexperienced ammonia and inexperienced transportation. ChemAnalyst, which research industries concerned in chemical commodities, suggests in a report that ammonia gas demand will develop by greater than 14% yearly to be used in transportation, energy technology, and industrial feedstock.
Mike Reese, renewable vitality director on the University of Minnesota’s West Central Research and Outreach Center, believes ammonia could possibly be one of many options for fueling equipment and storing vitality. Ammonia “is effectively understood and financeable” in comparison with different competing applied sciences equivalent to gas cells, he mentioned.
Reese mentioned the price of ammonia wants to say no to be aggressive, however it might nonetheless price lower than lithium-ion battery applied sciences.
“Batteries have confirmed to be very costly at scale and fewer is thought in regards to the efficiency,” he mentioned. “I believe it’s affordable to maneuver in the direction of energy technology utilizing ammonia in inside combustion engines.”
The measurement of all the market stays laborious to gauge however Kane supplies a glimpse of the generator market. In working with Grid Catalyst, Aza Power has been growing know-how to switch diesel in electrical mills. That market alone is “$35 billion to $40 billion globally,” Kane mentioned.
Pollution dangers
Kane mentioned Aza Power and different startups nonetheless want inexperienced ammonia from renewable vitality to develop considerably from its tiny market share. Even inexperienced ammonia, although, creates some emissions. When burned to supply vitality, inexperienced ammonia can emit nitrogen oxides (NOx) and nitrous oxides (N2O), which have a “world warming potential” 300 instances better than carbon emissions. Improved combustion applied sciences might assist scale back emissions dramatically, he mentioned.
Kane mentioned Aza Power meets NOx emissions set by the EPA through the use of mature catalytic formulations. The N2O emissions happen in any gas combustion, however Aza Power’s conversion know-how decreased greenhouse gasoline emissions, together with N2O, by 80% to 90% over diesel engines, he mentioned. He’s “assured” the quantity will rise to 98% subsequent 12 months.
Trevor Brown, govt director of the 262-member Ammonia Energy Association, mentioned Aza Power is exploring a doubtlessly profitable market of industries that might want to decarbonize automobiles and engines. Achieving net-zero emissions would require a portfolio of applied sciences, and ammonia’s world attain and transportability make it a potential resolution, he argued. The trade wants coverage help to compete with fossil fuels although.
“There’s no cheaper resolution than fossil fuels,” Brown conceded.
Aza Power’s foremost U.S. competitor is Amogy, a startup with almost $200 million in enterprise capital, primarily from Amazon’s Climate Pledge Fund. Amogy combines ammonia with gas cell know-how for decarbonizing the transportation sector and has developed an ammonia-powered tractor.
After the Grid Catalyst engagement ends, Aza Power desires to lift seed capital for an 18-month growth time to scale its technology know-how to greater engines. It is eyeing different markets, specifically locomotives working on diesel, and has a accomplice with experience in changing trains to run on different fuels.
Kane additionally sees the mining trade, an necessary participant in Minnesota, as one other market.
“Those functions in mining that use massive engines the place we’re scaling up our conversion applied sciences,” he mentioned.
