Submitted Comment Name Laura Haider Affiliation Fresnans Against Fracking Subject SB 1075 Technical analysis Message There are not yet any commercially available power plants that can burn 100 % hydrogen. Using renewables to produce hydrogen is 20 -40% less efficient than using renewable energy directly. (1) There would not be much need for hydrogen, since EVs are more efficient & cheaper to purchase than hydrogen vehicles. Also, diesel refining and plastic production would decrease. There would be economic recession due to the health impacts of fossil fuels and repeal of NEPA protections. We don't have enough EPA inspectors to find the upstream methane leakage. When hydrogen is combusted it produces NOx emissions up to 6 times worse than those released by methane combustion alone. Methods of controlling NOx emissions at gas power plants are only effective at controlling NOx at a blend of 30% hydrogen or less(1) Steel pipelines are susceptible to hydrogen embrittlement and cracking, therefore modifications of pipelines are necessary. Also leak detection systems would have to be updated. (1) Old oil and gas wells often leak, therefore are bad storages. One study found that if hydrogen were used in homes, the annual predicted number of explosions would more than quadruple. (2) (1) Sierra Club (2) Dept for Business Energy & Industrial Strategy's Hy4Heat Programme. The only potential for green hydrogen is to produce it from water using curtailed excess renewables and store it in fuel cells. File Upload (i.e., Attachments): N/A
