Aluminium maker Norsk Hydro to boost output, cut energy costs

Norwegian aluminium maker Norsk Hydro plans to transfer energy-saving technology from a pilot project to primary smelters in the next five to six years, boosting output and cutting costs, the company's head of technology told Reuters. Hydro on Monday announced the start of production at its new Karmoey plant, built to test and improve technology that the company says consumes at least 15% less energy than conventional aluminium production.
