Hydrogen cost

The cost of delivered hydrogen is the sum of the production, storage, and transportation costs. Tabe 1.3 summarizes delivered hydrogen costs for a wide range of production methods and three of the most often [Pg.19]

This result is highly dependent on the cost of delivered natural gas. Each 1 increase in delivered natural gas cost increases the estimated hydrogen cost by 0.16 /kg. [Pg.20]

Clearly, hydrogen distribution costs may be significant, suggesting that the future viability of a hydrogen economy may depend on achieving reductions in these storage and transportation costs. [Pg.21]

The National Academy of Engineering (NAE) (2004) reached a similar conclusion. Specifically, they found that pipeline shipment and dispensing would be the lowest cost option, at 0.96 /kg, ... which is essentially equal to the cost of production. The NAE concludes that even with possible future improvements in shipping and distribution, this cost is much more than today s gasoline dispensing and distribution costs, at 0.19 /gal. The NAE notes that this analysis demonstrates the realities of shipping H2 gas versus the much more efficient shipment of a liquid.  [Pg.21]


Cures, the equipment is made of vei y expensive high-alloy steels. Energy and hydrogen costs result in high operating costs, much higher per barrel of feed than the FCC unit. [Pg.986]

Figure 14.18 shows the average specific hydrogen costs (including feedstock, production, transport and refuelling), and the cumulated investment in hydrogen infrastructure aggregated for all countries for the FlyWays base case scenario. [Pg.437]

The delivered hydrogen cost over time is given by the aggregate hydrogen cost curve developed from our infrastructure modelling for this same vehicle introduction rate (Fig. 15.6). [Pg.474]

However, investments for hydrogen to reach cost competitiveness with gasoline on a cents-per-kilometre basis are even lower. This happens in about 2018 when hydrogen costs about 6/kg, because H2 FCVs are about twice as efficient as gasoline cars. Required infrastructure costs are perhaps 1-2 billion. [Pg.476]

For the economic evaluation, this price is compared with the costs of cheaper hydrogen production options, like natural gas reforming. With an operating time of 6750 h and a natural gas price of 2.35 ct/kWh, hydrogen costs are at 5.3 ct/kWh. This is much lower than the surplus wind pathway, if an electricity price of 4 ct/kWh is assumed. Further calculations have been performed, to show at what natural gas price natural gas reforming would reach hydrogen costs from surplus wind electricity the hydrogen price of surplus wind electricity is only reached at a natural gas price of 5.5 ct/kWh. If a carbon tax of 20/t is introduced, the necessary natural gas price is 5 ct/kWh (compare Fig. 16.10). [Pg.494]

If cyclohexane is worth 30 cents/lb., hydrogen costs 40 cents/lb., and it costs 0-5 cents/lb. of feed to run a traditional cyclohexane plant, how much can you afford to pay for benzene to break even Assume the light ends are flared (that is, they are burned off and worth nothing). [Pg.63]

The Skim Chemical Company can rent some IPA plant, acetone plant, and MIBK plant capacity from the Takes its Toll Company for 5 cents/lb. of product. When ethyl acetate is 40 cents/lb., what is the breakeven price that Skim can pay for propylene if the by-products of each plant are worthless but hydrogen costs 20 cents/lb. ... [Pg.252]

By 2010, verify renewable integrated hydrogen production with water electrolysis at a hydrogen cost of 2.50/kg (electrolyser capital cost of 300/kWe for 250 kg/day with 73% system efficiency). By 2010, verify large-scale central electrolysis at 2.00/kg hydrogen at the plant gate. [Pg.100]

The downside to the direct application of hydroprocesses to the heavy feedstocks is always hydrogen cost and catalyst life (also a cost). There is the potentially wasteful use of hydrogen with hydrogen sinks within the feedstock whereupon hydrogen is used but with little, if any, effect on the product character. [Pg.306]

These benefits, coupled with possible savings in catalyst consumption, unwanted by-product production, and hydrogen costs suggest that two-stage processing may be attractive in individual cases. [Pg.311]

In several countries, many activities on hydrogen production and cost assessments within the hydrogen economy are ongoing. Some countries have already developed their own models such as the German-French E3-database, the hydrogen cost analysis model in Canada, and other models in the United States. [Pg.283]

Thus, an electrochemical process for H2 recovery from H2S occurs at practical current densities of about half the energy needed for the recovery of H2 from water. h2s is plentiful the world over. Insofar as a market exists for the S, the income from the sale of by-product would more than compensate for the energy costs of the process, leading to negative hydrogen costs. [Pg.519]
