The U.S. Department of Energy is initiating an environmental review of hydrogen projects in the Northwest, following the region's designation as one of seven new "regional hydrogen hubs." The review will assess the potential adverse effects of developing hydrogen projects, focusing on infrastructure, design, and construction. The projects aim to promote the development and distribution of 'green' hydrogen, produced using renewable sources like wind or solar power, which does not emit greenhouse gases. Green hydrogen is crucial for reducing emissions in sectors that heavily rely on fossil fuels and are difficult to electrify due to high energy demands. The Northwest Hub's green hydrogen could be used in various applications, including fertilizer production and energy-intensive processes like semiconductor manufacturing, thus helping to mitigate carbon dioxide emissions. Despite the environmental benefits, the Northwest Hub faces challenges such as unaffordable renewable energy prices, lack of demand, and uncertainties surrounding federal support like tax credits. Public participation in the environmental assessment process is encouraged, with a virtual meeting scheduled for January and comments open until spring.
