Tugboat Powered By Ammonia Sails For the First Time
mardi 24 septembre 2024, 09:00 , par Slashdot
The tugboat ran on green ammonia produced by renewable electricity. A 2,000-gallon tank fits in the old fuel tank space, for a 10-to 12-hour day at sea. It splits liquid ammonia into its constituents, hydrogen and nitrogen, then funnels the hydrogen into a fuel cell that generates electricity for the vessel without carbon emissions. The process does not burn ammonia like a combustion engine would, so it primarily produces nitrogen in its elemental form and water as emissions. The company says there are trace amounts of nitrogen oxides that it's working to completely eliminate. Amogy first used ammonia to power a drone in 2021, then a tractor in 2022, a semi-truck in 2023, and now the tugboat to prove the technology. Woo said their system is designed to be used on vessels as small as the tugboat and as large as container ships, and could also make electricity on shore to replace diesel generators for data centers, mining and construction, or other heavy industries. The company has raised about $220 million. Amazon, an enterprise with immense needs for shipping, is among the investors. Nick Ellis, principal of Amazon's $2 billion Climate Pledge Fund, said the company is excited and impressed by what Amogy is doing. By investing, Amazon can show ship owners and builders it wants its goods delivered with zero emissions, he added. Read more of this story at Slashdot.
