@ Harvey D It is very difficult to capture a large percentage of CO2 from coal fired stations on the fkue gas side; it requires about -40% of the energy the statio produces to get 90% of the CO2.
Roger Pham The vat majority of H2 is currently produced by off gas from cracking processes or by using CH4. In that context yourt statement 'Hydrogen is the perfect replacement fuel for petroleum.H2 can be produced domestically with renewable energy, thereby phasing out petroleum importation and achieving energy independence.' makes absolutely no sence. While the US may be able to produce it domestically (unlikely as Canadian gas will probably be used) it would probably better off to just use CH$ in the first place.
Peel P50 could do 100 mpg in the 70's. tHat weas very small (worlds smallest car) so could only car one person. Lets see how this compares.
This does not seem terribly new. This form of treatment has been around since the 80's.
Lets see the data after scalue up to pilot scale. And how much longer did they last; do platnium cells have lasting issues??
@ Davemart First the basalt needs to be 'melted' at circa 1400C. This material then needs to be extruded in such a way as to produce a homogenous fiber. Without alluding to the massive problems of building something that can withstand 1400C, molten rock/minerals tend to glop up into balls. This means that controlling the material going to the extruder is difficult and this would lead to fiber homogeneity issues.
Take your pick Anne 'last 3 years' Aslo many of the grpahs are no longer than 30 years. And contrary Page 15 does not answer anything quantatively.
What I find interesting is thaat 1. No real analysis of the temperature decline is done or proven as to why such work is not needed. 2. Often anti GW guys are dismissed for nitpicking small timescales. Here we have a similar small timescale but no backlash; why?
I will update this to clear up the confusion. I only found this link as I just joined ECN. Apologies for that. The point of the membrane is that it can dehydrate organics. That means that it can replace molecular sieves for ethanol production and can be used instead of the high organic distillation column in butanol. Therefore it will always be coupled with another process for a mixture coming from the fermenter. This there will be distillation-pervaporation or pervaporation (using an MTR membrane)-pervaporation.
