Hydrogen in power generation. by Hakan Falk, "Energy Saving Now" http://energy.saving.nu/hydrogen/hydrogenpower.shtml One of the most controversial energy discussions, is the current US promotion of hydrogen usage in the transportation sector. We, among many others, have the opinion that this technology application is far from "ready for use" and that it is even not sure if it can be practically done. This discussions have such a high profile, that it overshadow many "ready for use" technologies and turns out to be more a diversion than a possible solution. A common misunderstandings is that hydrogen from electrolysis of water would be an energy source, when it in reality is an energy conversion and storage solution. One of the most interesting and "ready for use" applications that been overshadowed, is actually connected with hydrogen itself and is the use of hydrogen as storage in power generation applications. Hydrogen have been used for many years in stationary industrial applications and both experience and solutions are available for this type of use. A while ago, Norsk Hydro announced that they were engaged in developing solutions for this and it was a welcomed confirmation on the feasibility of this important and logical application. We have been quite enthusiastic for such a development for a long time and voiced suggestions of using it for solutions to the current Natural Gas (NG) crises in the US. The NG crises in US have been expected since the Reagan/Bush administration lifted the ban for use in power generation, that was introduced by the Nixon administration. The Nixon administration did their math correctly and concluded that the NG resources in US were too small for an unlimited us of NG. The ban in combination with actions that led to the largest energy savings in US history, did position US in a situation were they moved towards a control of their energy situation. The achievements was however reversed by the Reagan/Bush administration and their backers from the energy industry. This caused the situation were US known NG reserves only covers 7 years of current use. Combined with a lack of preparation for import of Liquified Natural Gas (LNG), the situation is now creating large difficulties for US industry. It is also a lack of known NG resources in the world, with a R/P (Known Resources/Production) value of only around 60 years. Because of the control equipment/policies for HVAC and the highly automated offices in the US, with the lack of utilization of mass for storage in HVAC, it is a large difference between low and peak demand for electricity. The under utilization of generation capacity during low demand could be used for production of hydrogen for use in the peak demand production. Hydrogen would in this case be used as a short term storage, to even out the demand cycles. If this was combined with changes in the control equipment/policies, it would be a large part of the solution of the peak demands with following capacity problems. It would also ease the current dependency on NG. It is "ready for use" and makes a lot of sense, why not doing it? The current hydrogen debate start to look as an eternal preparation, followed by no action. It is not natural, but maybe in line with current US trends. It is a lot of satisfaction in doing things also. Often it is better to use what you have, instead of waiting for a bigger one, that maybe does not work as good as the one you have. Timing is very important, it has to work when you need it!!! Hakan Falk ------------------------ Yahoo!
