On Tesla Trumps Toyota Part II: The Big Problem With Hydrogen Fuel Cell Vehicles

"The biggest problem hydrogen fuel cell vehicles face is that they deliver no obvious major consumer (or societal/environmental) benefit compared to the competition."

Carbon-negative hydrogen production makes this statement patently false.

On Tesla Trumps Toyota: Why Hydrogen Cars Can't Compete With Pure Electric Cars

William, one way to bring the of cost compressing hydrogen down is to produce it at depth using electricity produced by ocean thermal energy conversion. At a depth of 1000 meters where you would produce the gas by electrolysis the pressure is 100 atmospheres and the gas would arrive at the surface at that pressure. I think I have seen on these pages somewhere that this is about 1/3 the pressure that is desired but it gets you part way at no additional cost to the overall system.

On Water, Water Everywhere, Nor Any Drop To Drink

Yes I believe they added the decimal point incorrectly.


This application been abandoned by the way for lack of the resources to prosecute it.

On Tesla Trumps Toyota: Why Hydrogen Cars Can't Compete With Pure Electric Cars

And yet Mercedes Benz, Toyota, BMW, Hyundai ect. are developing hydrogen fuel cell cars. These guys aren't noted for their technological naivety.

Alistair I'm not clear on how you get 90% of the heat has gone into melting ice. The following diagram is based on James Hansen et. al. paper  “Earth’s Energy Imbalance: Confirmation and Implications, published in Science June 2005.

Joe, the making of hydrogen by ocean thermal energy conversion is a necessity to bring the energy to market. The work of Greg Rau's group at Lawrence Livermore Laboratories has demonstrated this process can concurrently sequester CO2.  You do not get this benefit from any means of producing electricity to power your EV.

On Why Does Politics Keep Getting in the Way of Pricing Carbon? - Part 1

 

Jesse if U.S. households are willing to pay $80-200 per year to combat climate change, I suspect they would more eager to invest that amount in technologies that accomplish the desired end, yet offer the chance of a return on investment.

On Carbon Sequestering Energy Production

Many thanks for the suggestion and vote of confidence Roy. I will certainly have a look at the opportunity. As to the suggestions about electrolysis I will let either Greg or Roger respond as they have far more expertise on that front than do I.

On Carbon Sequestering Energy Production

EP this dumping caused a huge backlash around here a year ago. In the same vain however this YouTube is essentially a synopsis of a presentation I made to the University of British Columbia Fisheries Department a year ago. A lot of people think the real problem with phytoplankton is thermal stratification.

On Carbon Sequestering Energy Production

According to a 2010 Scientific American article, What Is the Right Price for Carbon? $21/ton is too low but I take your point. There are a lot of wins for one technology and hopefully somewhere along the line the money guys will get it.

Roger, as I understand it the pH of sea water ranges between 7.5 and 8.4. The higher figure would be in the range where sodium bicarbonate would form according to the graphic. I am open however to the best way to accomplish the desired end. It seems to me the opportunity is presenting itself to solve the climate/energy problem.
