The higher efficiency of fuel cell vehicles compensates for the high carbon dioxide content of the fossil fuels. While the economic analysis was performed nearly two decades ago, it probably reflects a simplified strip-down bare design, and it does provide an indication on the relative cost of the various components such as materials, nutrients, labor, water use, land lease, power, and others, that are necessary and sufficient to assemble a commercially viable photobioreactor. Almost all6 of the cost estimates are developed for two different states of technology development. a CCGT turbine at 60% utilisation), the cost is $100/MWh, while simple-cycle turbines at 25% utilisation would deliver power at $200/MWh.”, Still, the report is optimistic. Instead we focus on the most important variables that drive the total cost of green hydrogen: The total cost of green hydrogen is therefore a function of capex + opex for the electrolyser, accounting for the lifetime and efficiency of the electrolyser. If this hydrogen is used to generate power, the resulting cost is $100 to $200/MWh. Still, it notes, a hydrogen cost of $6/kg delivered to a very remote location is required to breakeven, “which may be challenging to achieve.”. We are first in your inbox with the most important news in the industry―keeping you smarter and one-step ahead in this ever-changing and competitive market. Hydrogen Generation Plants and Production Technologies The production of pure hydrogen (up to 99,9999 vol.-%) is essential for a number of industries in very different fields. One way of achieving even lower production costs is to combine several functionalities in the same plant. These files contain macros necessary for hydrogen price calculation. Some may require significant technological breakthroughs. Updated plant start dates: current technology to 2015 and future technologies to 2040. Finding 5-7. To do this, we begin by focusing on the core deliverable product from an electrolyser and denominating all costs in relation to the final product: a kilogram of green hydrogen. The energy loss associated with LNG would be about 10 percent (8 percent to 12 percent). able during the transition, use of distributed natural gas may be necessary during the transition period, until centralized facilities and the required distribution system are built. FIGURE 5-5 Unit cost estimates for four current and four possible future electrolysis technologies for the generation of hydrogen. For instance, the, Hydrogen production in conventional, bio-based and nuclear power plants, Advances in Hydrogen Production, Storage and Distribution, without considering CCS retrofitting for these technologies. For instance, the hydrogen production cost from natural gas via steam reforming of methane varies from about 1.25 US$/kg for large systems to about 3.50 US$/kg for small systems with a natural gas price of 0.3 US$/kg. Costs are site-specific, particularly for wind and solar-based technologies; only single representative costs are reported. of all technology case studies are available for free. That means power plants need to upgrade piping and turbine engineers need to tackle problems such as higher volumes of gas flow.

Well-to-wheels energy efficiency would be increased with the possible future technologies, and so all of the hydrogen technologies would use less energy per mile driven than would the conventional gasoline-fueled passenger vehicle.

Table 5-3 includes these estimates, labeling the sensitivity as “low,” “medium,” or “high.” A blank cell in a column means that there is very low or no sensitivity to the particular parameter. For example, payback period concerns, where customers may prefer a quicker payback on capex, even if longer term costs are higher, or clients who operate on a merchant basis and who may value longevity of an asset over a lower upfront cost. The capital fixed costs were estimated at 80% of total costs, with the tubular material for the photobioreactor as the major cost. The gasoline cost assumes no increases in refining efficiency, and crude oil stays at $30/bbl.13 The committee estimates that hydrogen generated by central station nuclear energy, distributed natural gas steam reforming, and distributed electrolysis using wind-turbine-generated electricity would have costs within about $1.00/kg of the equivalent cost of gasoline used in GHEVs. However, the committee is making the spreadsheets containing the underlying data (see Appendix E) publicly available.

In the figure, the current technology is plotted as a square and the possible future technology as a triangle for each hydrogen production method. Thus, the possible future technology electrolyzers need only be 75 percent as large as the current technology electrolyzers. If 40 million hydrogen fuel cell vehicles were on the road by 2030 in Europe, this would equate to 19,000 hydrogen refuelling stations, costing €6–24bn ($8–33bn) which is comparable to the investments made in mobile phone and broadband infrastructure. NOTES: C= current technology; Y= sequestration (hydrocarbon feedstock in central station and midsize plants only); F= future technology; N= no sequestration. The cost differences between the possible future and the current technologies primarily stem from two factors: (1) The gasifiers are assumed to be reduced in cost and become more efficient—from 50 percent to 70 percent, with the appropriate successful research and development. FIGURE 5-7 Unit cost estimates for two current and two future possible coal technologies for hydrogen generation. Range of actual and allowable hydrogen production costs for different end uses. For gasoline-powered vehicles, the committee chose a gasoline hybrid electric vehicle (GHEV). For mid- and high-grade heat, biomass is an option, but it faces supply constraints, and CCS will likely be constrained to regions with access to carbon dioxide storage. Reactive materials are also important in their replacement costs, their reaction rate, and cycling efficiency. Capex: capital expense for the electrolyser (including the balance of plant). Figures 5-12 and 5-13 provide these estimates for current technologies and possible future technologies, respectively, with PEM fuel cell vehicles. and corrections: Updated cost of capital parameters: 40% equity financing, constant outstanding debt, The research group assumes a natural gas price of at least $6.50 per million British thermal units. This figure, compared with Figure 5-2, shows that reduced capital costs and reduced electricity costs are the most important differences.

There is no CO2 disposal cost included for distributed technologies; it is assumed that all of the CO2 is vented to the atmosphere. Nevertheless, current hydrogen production is mostly based at the large scale plants, producing circa 30 million tons of hydrogen per year in the US. From the distribution among the various cost inventories derived from the field operation, the costs of materials and nutrients turned out to be the major expenses (84%). Therefore, costs could be either higher or lower than the committee’s estimates.

for hydrogen refueling stations. Each central station plant could provide enough hydrogen to fuel about 2 million vehicles.
In 2020, the council also launched a new investor group, a membership category that currently comprises five European banks. Comparing this cost level with what would be commercially acceptable for different end uses (see right-hand side), it becomes obvious that only hydrogen sales to the transport sector make a positive economic case (without taking into account CO2 prices or regulatory measures). To illustrate the resulting utilization of electrolyzers when run on “surplus” electricity alone it is helpful to plot the residual load duration curves for different penetration levels of intermittent renewables.21Figure 11.4 depicts two typical residual load duration curves for a 30% and 80% share of generation from intermittent renewables of total electricity demand. Distributed production is considered by many authors to be the most likely pathway during the market development of energy systems. The nature of the improvements in each particular technology is discussed in Chapter 8; additional detail is provided in Appendix G. Generally these future technologies are assumed to be available at a significantly lower cost than that of the current technologies using the same feedstock.
