Scientists have put firm numbers on the high costs of installing pipelines to transport hydrogen fuel and also found a way to reduce those costs. Researchers calculated that hydrogen-specific steel pipelines can cost as much as 68 percent more than natural gas pipelines. However, they say, hydrogen transport costs could be reduced safely for most pipeline sizes and pressures by modifying industry codes to allow the use of a higher-strength grade of steel alloy without requiring thicker pipe walls.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/6EBeAjslKio» height=»1″ width=»1″ alt=»»/
