DOE analysis finds ongoing decrease in direct fuel cell vehicle costs
http://www.greencarcongress.com/2018/08/20180806-doefcev.html

A new analysis of the cost of current (2017) direct hydrogen fuel cell vehicles by a team from the Department of Energy, Argonne National Laboratory and Strategic Analysis found the lowest estimated system cost to date for high annual production rates.

The highest volume predictions, for 100,000 and 500,000 units per year, result in a total system cost of $50/kWnet and $45/kWnet, respectively. DOE’s 2025 target is $40/kWnet; the ultimate goal is $30/kWnet—essentially cost-parity with ICEVs. The analysis is published in the Journal of Power Sources. . . .

    The particular designs and components are primarily based on non-proprietary public reports, presentations by fuel cell companies and other researchers, and the patent literature. Although a system design and cost estimate based on open-source current technology systems is unable to probe as-to-yet unrevealed proprietary technologies in industry, a reasonable benchmark is possible on the basis of the publicly available information supplemented by quotes and feedback from industry and the fuel cell R&D community. Furthermore, the cost analysis relies on stack performance modeling from Argonne National Laboratory (ANL) and coordination with experts in manufacturing quality control at the National Renewable Energy Laboratory (NREL).

    Input gathered from an annual briefing of the assumptions and results to the US DRIVE (Driving Research and Innovation in Vehicle efficiency and Energy sustainability) Fuel Cell Technology Team (FCTT) grounds the baseline system in up-to-date, real-world experience.

    —Thompson et al. . . .

The team found that advances in increasing the power density and decreasing the platinum content of the cathode catalyst (set to a total loading of 0.125 g/cm2 geometric area) enabled the decreased cos. However, the catalyst and bi-polar plate cost remain the greatest contributors to the stack cost at high production volume, primarily due to the Pt and stainless steel content.

The team found that the cost of these commodity materials is less dependent on manufacturing volume; the researchers recommended that alternatives be pursued. The compressor-expander motor (CEM) unit remains the greatest single component cost in the balance of plant (BOP).

The authors said new designs and manufacturing methods are needed to decrease the air loop cost, which causes more variability in system cost than any other factor investigated, followed by air stoichiometry and power density. . . .

Ceres Power enters new partnership with Nissan on solid oxide fuel cell technology for EVs
http://www.greencarcongress.com/2018/08/20180803-ceres.html

Ceres Power and The Welding Institute (TWI) have been awarded a total of £8 million (US$10.4 million) from the UK government through the Advanced Propulsion Centre (APC) for this project.

The fuel-flexible SteelCell can generate power from conventional fuels such as natural gas and from sustainable fuels such as biogas, ethanol or hydrogen at very high efficiency. Made from mass-market and widely available materials, the SteelCell is cost-effective, robust and scalable, Ceres claims.

This project will involve the design, build, test and demonstration of a compact, robust, UK-produced SOFC stack, deployed within a Nissan-designed fuel cell module suitable for operation with a variety of high efficiency fuel types (including biofuels).

After a successful two-year Innovate UK funded development programme (EVRE – Electric Vehicle Range Extender), this project is the natural next step towards increased technology and manufacturing readiness for mass production of Ceres Power’s SteelCell for automotive applications. . . .

The expanded work with Nissan comes soon after Ceres Power’s recent announcement of a strategic partnership with China’s Weichai Power to develop its technology for China’s fast-growing electric powered bus market. . . .

Ceres Power has six strategic partners, including Cummins, Honda & Nissan, two as yet unnamed partners and a recently confirmed strategic investment partner in Weichai Power, which is primarily for range extension technology in China’s fast-growing battery-electric bus market.

Of course, as the title explicitly states:

As has been noted upthread, ultimate DoE goal for H2 fuel is $4kg untaxed, which will be cheaper than gas on a gge basis, but more expensive than electricity.

European INN-BALANCE project progressing with engineering a new generation of fuel cell auxiliary components
http://www.greencarcongress.com/2018/08/201808008-innbalance.html

The European FCH JU-funded project INN-BALANCE (INNovative Cost Improvements for BALANCE of Plant Components of Automotive PEMFC Systems) partners are tasked with developing a new generation of highly-efficient fuel cell Balance of Plant (BoP) components. These components are intended to support an innovative fuel cell system and hence greatly improve the efficiency and the reliability of fuel cell powered vehicles, while reducing their cost.

More specifically, INN-BALANCE is developing:

    a new air turbo-compressor

    combined hydrogen injection and recirculation

    advanced control and diagnosis devices

    a new concept of thermal management

As the efficiency of fuel cell powered vehicles depends on all components of the system being well-adjusted, INN-BALANCE also works on the smart integration of the newly developed components. An automotive fuel cell stack, with its novel components, will finally be incorporated into a vehicle powertrain to test its drivability, durability and performance.

INN-BALANCE is funded for three years (2017-2019) by the Fuel Cells and Hydrogen Joint Undertaking in the framework of the European Union’s research and innovation program Horizon 2020.

Now approximately halfway through the project term, the partners are now beginning to look to integrating the various components they have developed separately. . . .


CSIRO fills fuel cell vehicles with H2 produced by novel membrane technology; H2 from NH3
http://www.greencarcongress.com/2018/08/20180808-csiro.html

In a successful demonstration of technology capability, researchers at Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have filled Toyota Mirai and Hyundai Nexo hydrogen fuel cell vehicles using ultra-high purity hydrogen produced in Queensland using CSIRO’s novel H2-NH3 membrane separation technology.

Ammonia (NH3) has high capacity for hydrogen storage—17.6 wt.%, based on its molecular structure. CSIRO developed a thin metal membrane that can separate high-purity hydrogen from ammonia used as a hydrogen carrier, while blocking all other gases.

The technology can open the pathway for bulk hydrogen to be transported in the form of ammonia, using existing infrastructure, and then reconverted back to hydrogen at the point of use. The membrane links hydrogen production, distribution and delivery in the form of a modular unit that can be used at, or near, a refueling station. . . .

Following this successful demonstration, the technology will be increased in scale and deployed in several larger-scale demonstrations in Australia and abroad.

The project received $1.7 million from the Science and Industry Endowment Fund (SIEF), which was matched by CSIRO.

X-posted from the "California Retail H2 fueling stations" topic, some more quotes from the Executive summary of the 2018 CARB report (see above) can be found here: https://www.mynissanleaf.com/viewtopic.php?f=7&t=21315&p=534214#p534214

Also, the CARB report makes reference to the following Report:
Renewable
Hydrogen
Roadmap
This is the link to the 2-page Executive Summary: https://static1.squarespace.com/static/58e8f58d20099ea6eb9ab918/t/5afd25fff950b7543abe28f2/1526539786217/EIN_RH2_Summary_Highres.pdf

Haven't had a chance to read the whole thing (40 pages) yet, but here's the short version (I'm quoting the CARB report):
On May 17, 2018, the non-profit organization Energy Independence Now, with support from the Leonardo DiCaprio Foundation and the
California Hydrogen Business Council, published a Renewable Hydrogen Roadmap focused on opportunities and challenges in California’s
developing market [32]. The report builds from a premise that renewable hydrogen is a key technology for California’s carbon reduction goals.
In particular, hydrogen represents opportunities at the nexus between renewable sources of energy, the electrical grid “duck curve”* , and the
industrial and transport sectors. Through a series of analyses, the report provides a set of succinct policy recommendations with the potential
to facilitate renewable hydrogen production and utilization in the State of California.

The report also reviews the global and California-based current hydrogen supply, key stakeholders, and current applications. An overview of the
major production pathways for conventional and renewable hydrogen is presented along with their respective technologies, applications, current
utilization rates, and potential for growth. Logistical and economic challenges of each technology, including an analysis of distribution options, are
also described. The report’s eight policy recommendations for the adoption of renewable hydrogen into the California economy are:

1. Begin the journey to 100% renewable hydrogen now
2. Fund scalable projects for 100% renewable hydrogen production
3. Improve LCFS incentives
4. Promote tools to lower the cost of electricity for renewable hydrogen producers
5. Address hydrogen distribution and storage challenges
6. Expand the US Environmental Protection Agency’s Renewable Fuel Standard (RFS) program
7. Incentivize consumers and stakeholders
8. Broaden the hydrogen community through education and outreach

Here's the link to the full report: https://static1.squarespace.com/static/58e8f58d20099ea6eb9ab918/t/5afd25a9f950b7543abe21ba/1526539702668/EIN_RH2_Paper_Lowres.pdf

Finally, CAFCP has published the following (24 pages):
The California
Fuel Cell Revolution: A Vision for Advancing Economic, Social, and Environmental Priorities
https://cafcp.org/sites/default/files/CAFCR.pdf

As is always especially the case with industry-sponsored reports like the two above, consider the source applies.
