Decentralized Hydrogen Production Options

Centralized versus Decentralized Hydrogen Production Options [Pg.11]

Producing the hydrogen onboard as needed solves the infrastructure problem, but there are some dear drawbacks to the approach. The reformer would add to the cost of the vehide and take up additional room. The added weight would hurt fuel economy. A reformer placed at a centralized location might operate 80-95% of the time, but an onboard version would operate a fraction of that time and be an underutilized capital asset. Most importantly, if the original fuel is gasoline, then [Pg.11]

Perhaps the most compelling case for centralized production is that it would allow for greater diversification in terms of energy feedstocks, decreasing the vulnerability of the transportation sector through resource diversification. Of course, if there is a clear economic winner, such as coal gasification, then diversification may not happen. [Pg.12]

Centralized versus Decentralized Hydrogen Production Options... [Pg.11]

For the first decades, all roadmaps show a focus on fossil-based hydrogen production options, mainly onsite and decentral steam methane reformers (SMR), electro-lysers and hydrogen as a by-product from the chemical industry. In some regions, hydrogen is also produced to a certain extend by nuclear, electrolysis, biomass and waste gasification. Later on, with a significant increase of hydrogen, the production... [Pg.263]

The two options for hydrogen production at the station level are reformation of natural gas or electrolysis. Doubters of the decentralized approach will note the concern about natural gas availability and electricity generation capacity. Confronting those doubts requires understanding the potential increase in demand for natural gas that would be associated with the move to a hydrogen future. [Pg.243]
