The US government is investing $7 billion in seven hydrogen hubs along the East Coast, with the goal of reducing greenhouse gas emissions by 25 million metric tons per year. While experts agree on the potential uses for hydrogen - such as powering long-haul aviation and marine shipping, and producing ammonia for fertilizer - some question whether the tax credit will be effective in driving down costs and promoting sustainability. A recent study suggests that green hydrogen may not be cost-effective in industries like trucking, while others worry that without strict regulations on carbon capture, the industry could actually increase overall emissions.
