Hidden Value - If one thinks about coal-fired power plants, what is it that comes first into one's mind? The picture of high-value starting materials or rather the picture of low value carbon dioxide (CO2) emissions? Most people will probably end up with the latter one. However, the utilization of CO2 as a valuable raw material is not as devious as one would expect: Advanced research shows that it could be used as new source of carbon - thus replacing at least partially crude oil from which the element is normally extracted.
At present, the chemical industry is mainly dependent on petroleum, both as a feedstock and energy source - roughly 6-7% of the annual oil production is consumed by this sector. To become more independent in terms of energy, renewable resources and energy storage options are a matter of current research all over the industry.
