Battolyser B.V. Formed in the Netherlands

Proton Ventures and Delft University of Technology (TU Delft), both of the Netherlands, announced in early February the formation of a new company, Battolyser B.V.  The company’s initial goal is to build and demonstrate a pilot version of the eponymous technology that stores electricity and produces hydrogen.  Hans Vrijenhoef, who will direct the new company, indicated that a fully realized system would include an ammonia production train so that the hydrogen could be stored and transported at low cost.  Vrijenhoef is already the Director of Proton Ventures B.V., a member of the NH3 Fuel Association’s Global Federation Advisory Board, and the originator of the NH3 Event power-to-ammonia conference.

Ammonia-Hydrogen Energy Storage Highlighted in Australia

A new report from Australia identifies ammonia as a key part of a hydrogen-based high-volume energy storage system.  On November 20, Australia’s Council of Learned Academies (ACOLA) and its Chief Scientist released “The Role of Energy Storage in Australia’s Future Energy Supply Mix.”  In addition to hydrogen, the report covers pumped hydro, batteries, compressed air, and thermal systems.  Its rationale for including ammonia is starkly simple: “Hydrogen gas is difficult to transport due to its low density; instead, it is proposed that hydrogen is converted to ammonia for transport, and then converted back to hydrogen for use.”  Although an ultimate ranking of energy storage options is not provided, the hydrogen-ammonia combination arguably emerges as the best option in terms of economics, environmental and social impact, and deployability.

Ammonia for grid-scale power: Nuon, Gasunie, and Statoil

A new collaboration was announced last week, between Dutch power company Nuon, European natural gas pipeline operator Gasunie, and Norwegian oil major Statoil. The joint venture will look at converting one of the Magnum power plant's three 440 MW gasifiers, with hopes to have it running on hydrogen fuel by 2023. This is the continuation of the Power to Ammonia project and, although ammonia is not expected to be used in this particular stage of the project, converting Magnum to hydrogen fuel represents the "intermediate step" to demonstrate that "where hydrogen could be produced using natural gas by 2023, from the year 2030 it could be possible to produce it with sustainably produced ammonia ... Ammonia then effectively serves as a storage medium for hydrogen, making Magnum a super battery."

Power to Ammonia: The OCI Nitrogen – Geleen case

The Power-to-Ammonia feasibility study includes an assessment of the costs and benefits of producing ammonia from renewable energy at OCI Nitrogen's existing production site in Geleen. Of all the companies who joined forces in the Power-to-Ammonia project, OCI is the only ammonia producer. Its business case for making carbon-free ammonia is especially interesting therefore: not just because of the company's deep understanding of the ammonia market and available technologies, but also because it faces corporate exposure to the financial, operational, and social risks of relying upon a fossil-fueled technology in a carbon constrained future.

Power to Ammonia: The Stedin – Goeree-Overflakkee case

Goeree-Overflakkee, in the southwest corner of The Netherlands, already produces more renewable power than it can consume. But, by 2020, this small island will generate a full 300 MWe of solar and wind, which far "exceeds the electricity demand on the island, rated at maximum 30 MWe peak." Stedin, the local grid operator, has the expensive task of integrating these and future renewable resources into its electricity distribution system. The recent Power-to-Ammonia study included a detailed analysis of Stedin's business case for producing renewable ammonia as a way to store and transport this electricity - enabling the island to become a net exporter of clean energy.

Power to Ammonia: the Eemshaven case

The Institute for Sustainable Process Technology recently published a feasibility study, Power to Ammonia, looking at the possibility of producing and using ammonia in the renewable power sector. This project is based in The Netherlands and is led by a powerful industrial consortium. I wrote about the feasibility study last month, but it deserves closer attention because it examines three entirely separate business cases for integrating ammonia into a renewable energy economy, centered on three site-specific participants in the study: Nuon at Eemshaven, Stedin at Goeree-Overflakkee, and OCI Nitrogen at Geleen. Over the next few years, the group intends to build pilot projects to develop and demonstrate the necessary technologies. Next month, however, these projects will be an important part of the Power-to-Ammonia Conference, in Rotterdam on May 18-19. This article is the first in a series of three that aims to introduce each business case.

The Hydrogen Consensus

Let’s say there is such a thing as the “hydrogen consensus.” Most fundamentally, the consensus holds that hydrogen will be at the center of the sustainable energy economy of the future. By definition, hydrogen from fossil fuels will be off the table. Hydrogen from biomass will be on the table but the amount that can be derived sustainably will be limited by finite resources like land and water. This will leave a yawning gap (in the U.S., 60-70% of total energy consumption) that will be filled with the major renewables -- wind, solar, and geothermal -- and nuclear energy. This may be as far as the consensus goes today, but more detail is now emerging on the global system of production and use that could animate a hydrogen economy.

Ammonia for energy storage: economic and technical analysis

Developers around the world are looking at using ammonia as a form of energy storage, essentially turning an ammonia storage tank into a very large chemical battery. In the UK, Siemens is building an "all electric ammonia synthesis and energy storage system." In the Netherlands, Nuon is studying the feasibility of using Power-to-Ammonia "to convert high amounts of excess renewable power into ammonia, store it and burn it when renewable power supply is insufficient." While results from Siemens could be available in 2018, it might be 2021 before we see results from Nuon, whose "demonstration facility is planned to be completed in five years." But, while we wait for these real-world industrial data, the academic literature has just been updated with a significant new study on the design and performance of a grid-scale ammonia energy storage system.

TU Delft’s Battery-Electrolyzer Technology

On December 14, the journal Energy & Environmental Science published an article on a new technology, “Efficient electricity storage with a battolyser, an integrated Ni–Fe battery and electrolyser.” The lead author is Fokko Mulder, Professor of Materials for Energy Conversion & Storage at the Delft University of Technology (TU Delft) in the Netherlands. The system developed by Mulder and his collaborators accepts electricity from an external source and stores it in the conventional manner of all batteries. The twist is that when the battery is fully charged, any additional incoming electricity is used to generate hydrogen and oxygen via electrolysis. The technology may prove to be a valuable element in a grid-scale ammonia-based energy system.
