On the Ground in Japan: 5th Basic Energy Plan, LH2 Investment

Japan, widely recognized as a global leader in the development and implementation of ammonia energy, is a fascinating case study for advocates seeking a template for progress.  But, as Ammonia Energy has documented in numerous posts over the last two years, even in Japan the path is neither linear, smooth, nor preordained.  Two recent developments, one in the public sector and one in the private, illustrate anew the complexity of the evolutionary track the country is negotiating as it strives to create a sustainable energy economy.

Nel Stakes a Claim on Another Key Frontier of Hydrogen Implementation

On June 28, Norwegian hydrogen company Nel ASA issued a press release announcing that the company will supply “448 electrolyzers and associated fueling equipment to Nikola Motor Company as part of Nikola’s development of a hydrogen station infrastructure in the U.S. for truck and passenger vehicles.”  The Nikola-Nel arrangement is a globally significant step in the process of implementing a full-scale hydrogen energy economy.  And although its approach for supplying green energy to hydrogen fueling stations does not involve ammonia, it seems likely it will ultimately help make the case for ammonia as an economically advantaged option.

Toyota, 7-Eleven to Cooperate on Low-Carbon Convenience Stores

Last month, one Ammonia Energy post discussed Toyota’s participation in a Low-Carbon Hydrogen Project in its home prefecture -- including implicit support for ammonia as a hydrogen carrier.  Another post discussed Japanese manufacturer IHI’s plans to commercialize a small-scale combined heat and power system (micro CHP) based on direct ammonia solid oxide fuel cell technology.  Now, according to a June 6 Toyota Motor Corporation press release, Toyota and micro CHP have converged.

The announcement served as the unveiling of a “joint project” by Toyota and the convenience store chain 7-Eleven to develop “next-generation convenience stores aiming to considerably reduce CO2 emissions.”  The two companies initially agreed to cooperate in August 2017 on "considerations toward energy conservation and carbon dioxide emission reduction in store distribution and operation.”

Battolyser Attracts Grant Funding, Corporate Support

The kernel of the story is this: Battolyser B.V. is taking a step forward with the battolyser, its eponymous energy storage technology.  On June 12, Battolyser’s joint venture partners Delft University of Technology (TU Delft) and Proton Ventures announced that they had secured a €480,000 grant from Waddenfonds, a Dutch public-sector funding agency, to build a 15 kW/60 kWh version of the battolyser.  The installation will take place at Nuon’s Magnum generating station at Eemshaven in the Netherlands.  The move makes tangible the vision of the battolyser as an integral part of an energy supply system with a robust quota of renewably generated electricity.

The battolyser is a battery that stores electricity in the conventional galvanic manner until it is fully charged.  At that point, the device uses any additional electricity supplied for the electrolysis of water and evolution of hydrogen.  If the device is integrated with hydrogen buffer storage and an ammonia production train, the result will be a versatile and highly scalable energy storage system that can provide highly responsive grid support on all time scales from seconds to months.  (Ammonia Energy last posted on the battolyser on March 1, 2018.)

Sawafuji Moves toward Commercialization of NH3-to-H2 System

On May 28 Sawafuji Electric Company issued a press release detailing advances made over the last year on the ammonia-to-hydrogen conversion technology it has been jointly developing with Gifu University.  The main area of progress is the rate of hydrogen generation, but the key takeaway from the announcement is that Sawafuji has set a schedule that culminates in product commercialization in 2020.

The Offshore-Wind / Ammonia Nexus

In early April the Business Network for Offshore Wind held its 2018 International Offshore Wind Partnering Forum in Princeton, New Jersey in the U.S..  Ammonia energy was not on the agenda, at least as a matter of formal programming.  But it did come up during a panel session entitled “Offshore Wind Energy Hydrogen Production, Grid Balancing and Decarbonization.”  We know this because Steve Szymanski, Director of Business Development for Proton OnSite (a subsidiary of Norway’s Nel ASA), was on the panel and says he was the one to bring it up.  The topic attracted “a lot of interest and a lot of good questions,” Szymanski said.  Nel is an industry member of the NH3 Fuel Association.

Australia’s Woodside Petroleum Considers Ammonia as a Hydrogen Carrier

At last week’s Australian Petroleum Production and Exploration Association Conference, Woodside Petroleum’s chief executive officer Peter Coleman spoke about the “huge” opportunity in hydrogen energy that will develop for the company over the next 10-15 years.  Coleman sees the Japanese market for hydrogen as a promising destination for Woodside’s substantial reserves of natural gas, and indicated the company is evaluating alternative methods of hydrogen transport including as liquid H2, a liquid organic hydride, and ammonia.

Carbon Capture Set to Advance in the U.S.

The United States Congress passed a measure on February 9 that could galvanize the production of low-carbon ammonia in the U.S.  The measure, included within the Bipartisan Budget Act of 2018, amends Section 45Q of the Internal Revenue Code, titled “Credit for Carbon Dioxide Sequestration”.  That section, originally adopted in 2008, created a framework of tax credits for carbon capture and sequestration.  45Q’s impact in the intervening years has been minimal, an outcome attributed by experts to the relatively low prices assigned to CO2 sequestration and the fact that tax credits would be allowed only for the first 75 million tonnes of sequestered CO2.  The new legislation increases the tax credit per tonne of CO2 placed in secure geological storage from $20 to $50, and for CO2 used for enhanced oil recovery from $10 to $35.  It eliminates the credits cap altogether.  With these changes, it now seems possible that low-carbon ammonia could find itself on an equal economic footing with “fossil” ammonia – and this could have consequences well beyond American agricultural markets.

Toyota Supports H2 Society Roll-Out on Its Home Turf; Sees Role for NH3

Toyota Motor Corporation announced on April 25 the launch of an effort called the Chita City and Toyota City Renewable Energy-Use Low-Carbon Hydrogen Project.  According to the company’s press release, the project is intended as a step toward “the realization of a hydrogen-based society spanning the entire region through mutual coordination and all-inclusive efforts.” 

For ammonia energy advocates, the announcement had two elements of particular significance. First is the clear indication that Toyota Motor Corporation is embracing ammonia as a hydrogen carrier – although not as a motor fuel.  Second is the project’s stated intention to establish a “system in which Aichi Prefecture certifies low-carbon hydrogen objectively and fairly.”
