Development Of A Centrifugal Hydrogen Pipeline Gas Compressor

Delivering 100,000 to 1,000,000 kg/day of 99.99% • hydrogen gas from generation site(s) to forecourt stations. Compressing from 350 psig to 1,000 psig or greater. • Reduce initial installed system equipment cost to less than $9 M (compressor package of $5.4 M) for 240,000 kg/day system. Reduce package footprint and improve packaging • design. Achieve transport delivery costs below $1/gasoline gallon equivalent (gge) ($2008 goal). Reduce maintenance cost to below 3% of total capital • investment. Increase system reliability to avoid purchasing • redundant systems. Maintain hydrogen efficiency (as defined by DOE) to • 98% or greater. Reduce H • 2 leakage to less than 0.5%.
