Some major issues with the proposed plans:
- Energy Efficiency in vehicles: A BEV takes 1.53 MJ of energy consumption to put 1.00 MJ of energy into the wheels of the vehicle. An equivalent Hydrogen fuel cell (using renewable energy the most efficient path) requires 4.50 MJ to put that same 1.00 MJ into the wheels. It is significantly more efficient and more simple (no need to build out tons of new infrastructure) to utilize existing widespread battery technology. Linked studies from non-industry academics: https://css.umich.edu/publications/research-publications/green-hydrogen…
-On Page 14 of the provided E3 presentation it listed the emission intensity of each method of producing Hydrogen. It is very clear that no low or negative options are available today and since the Oil and Gas industry lobbyists are supporting Hydrogen legislation like this and others across the state, it seems quite likely that they will be dictating which emission intensive option the state uses. Until there is a clear concurrent path to Green Hydrogen and a legal obligation to not use emission intensive options then Hydrogen should not be seriously considered.
-Hydrogen is prone to leaks. As an aerospace professional there is some common knowledge that using Hydrogen as fuel is incredibly difficult. For a great example take a look at NASA's long history of scrubs and delays of launches due to hydrogen leaks despite decades of experience working on a handful of vehicles using the fuel, seen recently in their Space Launch System launch in Nov 2022. On page 36 is states that Hydrogen low volume leakages are "challenging to quantify". Are we going to rush head first into this and see in ten years we are losing 10% of Hydrogen to leaks? This issue needs to be quantified and well understood before committing to widespread usage.
-Take a peak at the attached simple chart from Energy Innovation Policy & Technologies I have attached from this study: https://energyinnovation.org/report/hydrogen-policys-narrow-path-delusi…. Its a great starting point when thinking about viability of Hydrogen usage.

Please move into Hydrogen very carefully. Please do not use it as an excuse to renege on our energy efficiency and emission targets by excluding production/transportation factors.
