Hmmm looking for a replacement for natural gas to eliminate GHG emisions. This is good news and smart considering the rise in the price of natural gas.

Most large users of fossil fuels from the mining industry, smelting, and transportation are looking at ways of lowering and eliminating their GHG emisions.Not just because they don't want to seen as a GHG contributor they are forward looking at the price of these fuels in the future. The EU country's governments are moving faster on finding new ways of lowering and elimiating GHG emisions. From taxes to having manufactures list how their products were produced and awarding contracts based on the carbon footprint. When this happens in places like the US steelmakers will be forced to switch from being the cheapest to being the greenest when bidding on infrastructure contracts like bridges.
