Judges'' comments
Thank you for your submission to the Climate CoLab. The Judges have carefully reviewed your proposal, however, have decided not to advance it to the next round. While the Judges felt it was an interesting concept, they had concerns around feasibility.
We encourage you stay engaged with the Climate CoLab and to continue to develop your idea.
Judges' feedback:
Natural has is used for heating because it is more efficient than electric, so I suspect few people who have natural already would be willing to forgo this to use your technology. Plus I am not sure it is as simple as just using the natural gas pipelines for hydrogen - there may be a lot of technical modifications that need to be made that would make it costly. This would need to be dealt with in your proposal if you want to focus on this solution. I prefer the idea of using algae, although there are also a lot of questions there - if the process is technically difficult, what would be required of a user to run the system? What type of temperature control etc. would the algae need? These constraints may make it simply too costly to use at the home. Plus, would you need to store any hydrogen, or are you using it immediately and just feeding it back into the grid? If so, why not produce it all at a dedicated algae power plant instead of at the home? You need to clarify what the advantage is to producing it at the home. I like the idea of using the water produced, and this is a particular advantage of hydrogen fuel cells, over other renewable electricity sources. I also like the idea of someone like Tesla selling the system, if it is to be at the home.Your proposal would be much stronger if you could have an estimate of the emissions reduction associated with it - and try to be conservative - don't oversell. The proposal would also be stronger if you had an estimate of costs for furthering the idea - i.e., next steps.
