Thank you for your proposal and welcome to the ClimateColab.
Hydrogen has some advantages like high energy density and relatively cheap storage.
However, indirect emissions are not eliminated from the use of hydrogen. The opposite is the case, hydrogen production is very energy-intensive and causes higher emissions than the direct usage of electricity from natural gas. Thus, battery electric vehicles would be a better choice.
Production of hydrogen from renewable energy is very expensive at the current stage and it is questionable whether the technology will evolve. And again, energy consumption is higher than the direct usage of renewable electricity. So why not advance pure battery electric vehicle technology?
You might want to address these issues.

@paulw As outlined in the proposal, hydrogen production will not be generated using traditional fossil fuels or even renewable energy sources, as it is extremely inefficient. The proposal utilizes unique biological processes that produce large quantities of hydrogen via algae/bacteria growth. There are many papers exploring this topic of research, and significant progress has been made regarding the development of large scale hydrogen production. The sources are cited at the end of the proposal. Thank you for your input.
