Click to enlarge. To offer completely green power, we are working on the development of an eco-friendly process to create green ammonia that can displace the pollutant Haber-Bosch process. Ammonia has a number of favorable attributes, the primary one being its high capacity for hydrogen storage, 17.6 wt.%, based on its molecular structure. The low population density allows only little energy storage and electricity export is difficult due to the isolated location. This source of ammonia would be a clean alternative to the industrial ammonia that is produced via the Haber-Bosch production process. I am aware of many studies considering this proposition, although there are several challenges in ammonia combustion, such as low flammability, high NOx emission, and low radiation intensity. On the other hand, their disadvantages include their significant weight and footprint, their high production costs, rapid deterioration, safety hazards and problems around their disposal. In parallel to batteries, another popular trend for energy storage is based on hydrogen technology, such as applications that leverage hydrogen to drive fuel cells, chargeable vehicles and mobile machinery, among other innovative applications. High availability fuel cells can be an important component of these solutions. Ammonia plant cost comparisons: Natural gas, Coal, or Electrolysis? The paper cites an estimated requirement of up to 28 GW / 40 TWh of “compensating capacity” in Germany, “and five times more in the United States for successful integration of fluctuating renewables.”. Transportability – ammonia is easy to store and doesn’t require high-pressure storage. Learn about membership →. The heat of formation of ammonia is 30.6kJ/molH2. We showed that a nitrogen economy, where renewable hydrogen is chemically stored on abundant nitrogen in the form of a nontoxic and safe nitrogen-based alternative fuel, is energetically feasible, and that novel nitrogen-based fuels are comparable on an energy-return basis to existing carbon-based fuels. Solar thermochemical energy storage (TCES) exploits a chemically reversible reaction by using solar energy to heat an endothermic reactor. The major advantage of the ammonia-based system is the much broader applicability, because it is not constrained by geological conditions. And the pure oxygen stream produced by water-splitting is reused to power the fuel cell. This special interest group is for professionals to connect and discuss all types of carbon-free power alternatives, including nuclear, renewable, tidal and more. The NH3 fuel supply could be trucked in as easily as diesel is now. In addition to ammonia, reactions involving hydroxides, carbonates, hydrides, and sulfates, as well as methane reforming, have been investigated as TCES media (see pp. The price of bulk ammonia for agricultural use appears to be around $550-$600/ton, which equates to $1.55-1.70/gal. The reason is because energy storage as hydrogen is challenging. The ammonia is stored in a tank and converted back into electricity when needed, either through traditional combustion methods or by ‘cracking’ it into nitrogen and hydrogen. I would think that a grid that reaches massive penetrations of renewables-- say 80% for now rather than focusing on 100%-- would have diverse energy storage uses. The answer to this challenge will come from readily available renewable energy storage solutions. In Israel, researchers recently published a complementary study that compared carbon-based and nitrogen-based synthetic fuels. So why hasn’t this technology conquered the market? The process is conducted at a pressure of 200 atm and high reaction temperatures of nearly 500°C. Fuel cells that can harness hydrogen from ammonia offer significant breakthroughs in overcoming the key challenges of green energy: Solar energy is produced only when the sun shines. Ammonia is generally more economical than hydrogen as a single method of energy storage. However, they promise to address this in the next stage of their research: The agile operability of the start-up/shut-down processes, for example, determines the frequency of the cyclic operation and thus the applicability of the energy storage system … Regarding the design methodology, given a variable load trajectory, such as a power supply curve from a large-scale wind park, sizing an energy storage system requires an evaluation of the time-dependent deployment of the system … The system design and operation of the ammonia-based energy storage system under time-variant operation will be investigated in a future publication. The advantages are many. Although it is a gas at room temperature, it is much more readily liquified than hydrogen, enabling large quantities of energy to be stored and transported. First, the reversible fuel cell must become proven: “The development of the RSOFC is still in an early stage. Marquardt et al: Conceptual Design of Ammonia-Based Energy Storage System: System Design and Time-Invariant Performance, AIChE Journal 01/28/2017. Because this equation includes no carbon, when matured, this technology will allow us to have 100% green distributed power generation. Standby diesel generators need to be run for a few hours every month to turn over their fuel supply. Ammonia is considered to be a potential medium for hydrogen storage, facilitating CO2-free energy systems in the future. The fact that the availability of these increasingly popular sources of renewable energy is limited by weather conditions grows in importance as these power sources make up a greater portion of the total energy generated. Today these fuel cells run on industrially produced ammonia, mainly produced via the commonly used but highly pollutant Haber-Bosch process. The aim of the demonstrator is to show that not only could this process be used to dramatically reduce emissions from the production of ammonia for conventional uses, but that ammonia can also be a practical hydrogen energy vector, further reducing CO2 emissions across our energy systems by providing for the storage of renewable energy at scale. The 3-step process is as followed: 1. Second, improvements to the Haber-Bosch process would not only increase efficiency but also social acceptance, because the “high pressure (over 200 bar) … raises concerns about system complexity and safety. The energy storage properties of ammonia are fundamentally similar to those of methane. Ammonia could be a useful method of energy storage and transport that has the potential to be carbon-free in the right conditions. We envision enabling a fully clean energy loop by producing green ammonia on-site using solar and wind energy, using the ammonia to run alkaline fuel cell generators anywhere beyond the grid, enabling rural electrification and bringing the world closer to grid parity. Started from 2017, this year also wind energy in India couldn’t see any remarkable progress, though highly expected. The energy density for ammonia is 11.5 MJ/l, gasoline is 34.2. Another key advantage is ammonia’s chemical compatibility with alkaline fuel cells which use an alkaline electrolyte. As there is no carbon, no carbon by-products are produced – so ammonia is thus a "carbon neutral" option for the future. To put this into context, based on an energy content of about 3 MWh per metric ton of ammonia, meeting this demand with ammonia would require additional ammonia production capacity of around 13 million tons per year in Germany, or 65 million tons per year in the US, roughly four times the existing installed ammonia capacity in each country. I note that this levelized cost of delivered energy, at $0.24 per KWh, is better than the target set by the US Department of Energy’s ARPA-E in its “REFUEL” program, which specified a competitive “source-to-use energy” cost of $0.30 per KWh in its funding announcement for ammonia as a carbon neutral liquid fuel. In today’s Haber-Bosch process, air and hydrogen gas are combined via an iron catalyst. Annual global produ… When the grid that powers NREL's Flatirons Campus went down, engineers put the site's experimental microgrid to work. You need to be a member of Energy Central to access some features and content. Rami Reshef serves as the CEO of GenCell Energy, a developer of alkaline fuel cell solutions that generate clean, reliable off-grid and backup power for humanity. Mass, centralized hydrogen production, whether as gas or liquid, entails high delivery and distribution costs, while low-volume distributed production is prohibitively costly. The storage capacity of energy as hydrogen is far higher than that of batteries. However, the German paper also specifies a second system: the first, with energy efficiency of 72%, was optimized without regard for cost; the second was optimized for cost, and yet it still displayed a round-trip efficiency of 64%, more than double the energy efficiency cited in the Oxford paper. The German paper represents an important advance on previous studies because its analysis is based on advanced energy technologies with a focus on process integration. Pure oxygen, produced as a side-product in electrochemical water splitting, is used to drive the fuel cell …, The system can achieve a round-trip efficiency as high as 72%. Our mission at Energy Central is to help global power industry professionals work better. The Ammonia Energy Association is the global agent of collective action for the ammonia energy industry by creating, collecting, organizing, and disseminating relevant knowledge for the responsible use of ammonia in a sustainable energy economy. Varied technologies are used to develop rechargeable batteries of different types and sizes. That's in fact the nub of the problem with 100% renewables as a concept. Firstly, ammonia is economical. A pressure reduction helps increase the societal acceptance of the proposed concept.” I’ve written about the development of such low-pressure adaptations to the Haber-Bosch process, including projects funded under the US Department of Energy’s ARPA-E “REFUEL” program. This is achieved through process integration: designing a system specifically for energy storage, instead of piecing together existing technologies without synergy. Store the synthetic ammonia in large tanks the energy can be stored as long as needed and therefore provides a fuel stock for those moments when there is … 30–35) (1–3). But Agility and “Tightrope walking” required for the Quest (Part II), Batteries Included: Creating Value with Behind-the-Meter Storage, Mass Gigawatt Storage is closer than you may think, New DOE-Backed Project Will Tackle Barriers to Energy Storage Interconnection, Batteries used as virtual power lines for more renewables. Bañares-Alcántara et al: Analysis of Islanded Ammonia-based Energy Storage Systems, University of Oxford, 09/2015, Obviously, increasing round-trip efficiency to 72% presents a major advancement, and should encourage broader consideration of ammonia-based energy storage systems. There are claims that the Haber-Bosch process is one of the largest contributors to a build-up of reactive nitrogen in the biosphere. Scientists are working on novel hydrogen carriers to overcome these constraints. And when ammonia is cracked to produce hydrogen, no harmful pollutants are emitted. Urea production is not carbon sequestration, JGC Corporation demonstrates "world's first" carbon-free ammonia energy cycle, Creative Commons Attribution 4.0 International License. Let's face it when one looks at the projected load duration curves with higher penetrations of renewables, you would literally have to produce exponentially higher amounts of ammonia. Ammonia could be utilized in the instances where supply is far exceeding demand for some appreciable amount of time and serve as an economic source for excess renewable generation to go rather than curtailing it, storing it for a later season. In other words, the energy storage market dwarves the fertilizer market. The first step would be eliminate all the Ammonia produced by coal - fortunately economics are doing a good job with this, but there is still considerable Ammonia capacity using coal as a feed stock. But the biggest advantage of ammonia as a hydrogen carrier is the fact that as a liquid, with mild pressurization and without cryogenic constraints, it offers a high hydrogen storage density. Already today GenCell has developed a fuel cell that leverages liquid ammonia to fuel an off-grid power solution which acts as an autonomous “nano-power plant” beyond the grid, enabling us to replace pollutant diesel generators in providing electricity beyond the grid. However, in order to release hydrogen from ammonia, significant energy input as well as reactor mass and volume are required. Actually, Ammonia IS a better energy storage option than hydrogen. If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. Environmental Performance NH3 Fuel is environmentally friendly, producing zero carbon dioxide and low overall emissions. Grader et al: Nitrogen‐Based Fuels: A Power‐to‐Fuel‐to‐Power Analysis, Angewandte Chemie, 07/25/2016This Israeli study provides a comparison between ammonia and other, more frequently discussed carbon-based synthetic fuels, including methanol and DME, and still concludes that ammonia has the highest round-trip efficiency, according to their Power-to-Fuel-to-Power (PFP) analysis. Hydrogen & Offshore Wind, business advisor and trainer. Fundamental issues, such as cell fabrication methods and reversible operation, still require further research.”. First convert your electricity from wind in liquid ammonia a chemical process, in which hydrogen is bonded to nitrogen, in order to make ammonia 2. But when you factor in its lower energy density, that raises it to at least … Seasonal supplies of ammonia can easily be stored in mildly pressurized and widely distributed above-ground tanks. I.e., giant salt caverns or capped sedimentary rock formations with adequate porosity and permeability. Additionally, systems which use both hydrogen and ammonia outperform those which use only one storage option and have LCOE between $0.17/kWh and $0.28/kWh, including full investment in renewable generation infrastructure. Hi Gary, I would venture to say that using green ammonia to reduce the enormous costs of building a hydrogen supply chain infrastructure for the energy sector and using green ammonia to decarbonize fertilizer production are two separate yet equally important and valid efforts. Do you see energy stored as ammonia predominantly being used as a direct fuel-- is there any work being done to then use ammonia-to-power, or would the inefficiencies created in that process make it uneconomical? An ammonia-based energy storage system is proposed. The unanswered question is what share of the energy storage market could be captured by ammonia-based systems but, whatever fraction it will be, this presents a significant business opportunity for ammonia synthesis technology providers. The crucial difference is the central atom, where, when burnt, the carbon atom in For an equal amount of energy storage you need 3 times the volume for ammonia. Ammonia is burnable substance and has a side as an energy carrier which is different from other hydrogen carriers. As such, it demonstrates what ammonia can realistically achieve in the near future, not just what it was constrained to do in the past. As it heats it changes from its initial form of the molecule norbornadiene into its heat-trapping isomer, quadricyclane. Therefore, the investment cost may increase significantly, if only an expansion of the energy capacity is expected.”, The ammonia-based energy storage system presents an economic performance which is comparable to the pumped hydro and the compressed air energy storage systems. Technically speaking, it could work. (The Oxford paper, which is 157 pages long, nonetheless provides a valuable analysis.). Energy storage – ammonia is easily stored in bulk as a liquid at modest pressures (10-15 bar) or refrigerated to -33°C. Hydrogen is what's usually proposed. Ordinary diesel fuel, in contrast, contains reactive hydrocarbon species that can slowly polymerize and "gunk up" the fuel system. In the latter method, the hydrogen can then be used in hydrogen fuel cells to power devices such as electric vehicles. There are already at least two market segments for which ammonia and fuel cells offer an environmentally -- and perhaps economically -- superior solution to incumbent diesel generator technology. As there is no carbon, no carbon by-products are produced – so ammonia is thus a "carbon neutral" option for the future. Applications such as electrolysis produce clean, green hydrogen from water with the aid of surplus renewable energy; this hydrogen can be transported, stored and enable re-electrification using fuel cells. The power plant will be transformed to a mega battery to store excess green power from wind energy. Our, Already today GenCell has developed a fuel cell that leverages liquid ammonia to fuel an off-grid power solution which acts as an autonomous “nano-power plant” beyond the grid, enabling us to replace pollutant diesel generators in providing electricity beyond the grid.

For large-scale (MW / GWh) and long-term (hours-days) storage, this system beats batteries because of its low cost: for batteries, the “sizing of the energy capacity and the power capacity cannot be separated. Excel file, updated quarterly. That would help with the cost effectiveness of building out new generation sources as well because there would be a use for overbuild and overgeneration. Ammonia is the suitable alternative fuel because it has 18.6 MJ/kg energy density at NTP and carbon-free combustion byproducts. These studies make a compelling argument for the consideration of ammonia-based energy storage systems but, while we wait on data from industrial demonstrations, the German paper outlined a series of questions yet to be answered. Marquardt et al: Conceptual Design of Ammonia-Based Energy Storage System: System Design and Time-Invariant Performance, AIChE Journal 01/28/2017The authors illustrated these trade-offs between cost and energy efficiency in a chart that shows how the second system reduces capital costs, including an almost $200 million saving in heat exchangers. Reliability Compliance Specialist, Electric & Gas Utility Journey Relay Technician. There are over 800 retail NH3 distribution facilities in Iowa alone. Producing ammonia without carbon emissions is possible and the roadmap that this article summarises describes the pathway towards this in terms of three generations, the third of which is the electrochemical approach. This would enable industrial production of clean ammonia using renewable energy for a wide range of applications, from fertilizers and water purification to providing fuel for alkaline fuel cell solutions. Another option is to use ammonia as an energy carrier. Please sign-in or register to continue. This makes it an ideal chemical store for renewable energy. In the Haber-Bosch ammonia synthesis process, nitrogen reacts with hydrogen using a metal catalyst. So as we move down these various paths we need to consider all aspects. This performance was measured against a benchmark system that consisted of separate units, including a PEM-electrolyzer, Haber-Bosch synthesis unit, and a gas turbine, which displayed “a round-trip efficiency of as low as 34.2%.” For context, this benchmark is consistent with the out-dated Oxford paper, which had concluded: As a solution for grid-level storage, ammonia seems a poor choice primarily because of its relatively low round-trip efficiency (23-41%) compared to other emerging technologies such as liquid air (50-70% round-trip efficiency) and pumped heat energy storage (72-80%). To balance the load from intermittent renewables, these two functions are required at different times, so achieving both with one piece of technology reduces the system’s capital cost. Furthermore, it is not constrained by local geology in the same … Grader et al: Nitrogen‐Based Fuels: A Power‐to‐Fuel‐to‐Power Analysis, Angewandte Chemie, 07/25/2016. For more information, contact us at team@gencellenergy.com. How much additional energy production (and, importantly, monetization) would this bring for new panels compared with the state of the art already... Senior Vice President & COO (Engineering and Operations), Control Room Operator/Performance Engineer, Reliability Compliance Specialist/Sr. Ammonia has the lowest required energy for feedstock separation, even when compared to carbon‐based fuels in the case of flue‐gas‐derived CO2. Until today, the energy market has been primarily focusing on two main approaches to Renewable Energy storage – rechargeable batteries and hydrogen. The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other. Robertson is chairman and CEO of Light Water Inc., an ammonia energy storage startup. While ammonia is a toxic chemical with a potent odor, when handled with care and in accordance with regulations it is safely used in agriculture, refrigeration, semiconductors, hair dyes and water purification among other applications. 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.”. Those exist, but they're geographically limited. The ammonia-based energy storage system demonstrates a new opportunity for integrating energy storage within wind or solar farms. In the all-solar thermal power generation, the thermochemical energy storage is a key step. Compared to hydrogen as a fuel, ammonia is much more energy efficient, and could be produced, stored, and delivered at a much lower cost than hydrogen which must be kept compressed or as a cryogenic liquid. Its high volumetric hydrogen density, low storage pressure and stability for long-term storage are among the beneficial characteristics of ammonia for hydrogen storage. A centralized database where products have embedded emissions verified and listed, similar to a nutritional label, would absolutely be a gamechanger. Most important, in my opinion, is that ammonia offers a more viable evolutionary path for business development.

Whe you say direct fuel I assume you are referring to the use of ammonia as a fuel for a combustion engine. To offer completely green power, we are working on the development of an eco-friendly process to create green ammonia that can displace the pollutant Haber-Bosch process. “Ammonia presents certain technical challenges, but even though it is corrosive, the safety trade-off between ammonia and hydrogen favors ammonia” added Cheliotis. Here's a look at some of the most common problems and how to troubleshoot them. Hydrogen carriers can store hydrogen in a chemical state other than free hydrogen molecules. The misalignment of renewable energy production vs consumer demand is demonstrated in the now famous Renewable Energy duck curve; the fluctuations in energy balances caused by Renewables create serious challenges for power utilities that must meet this demand. On the other hand, the idea of using ammonia-to-power technologies as a carrier for hydrogen to be used with fuel cells and for decarbonization of carbon-intensive industries such as shipping is gaining traction and support in both R&D and industrial settings around the world. electric ammonia synthesis and energy storage, Conceptual Design of Ammonia-Based Energy Storage System: System Design and Time-Invariant Performance, Analysis of Islanded Ammonia-based Energy Storage Systems, Nitrogen‐Based Fuels: A Power‐to‐Fuel‐to‐Power Analysis, Industrial demonstrations of ammonia fuel in Japan, Pipeline of new ammonia plants (2017 update, part 1), Ammonia for energy storage: economic and technical analysis – Ammonia Energy, Ammonia for energy storage: a “revolutionary disruption” – Ammonia Energy, ThyssenKrupp's "green hydrogen and renewable ammonia value chain", Small-scale ammonia: where the economics work and the technology is ready, Download: Ammonia Capacity in North America, Ammonia technology portfolio: optimize for energy efficiency and carbon efficiency, Green ammonia: Haldor Topsoe's solid oxide electrolyzer. Hence for hydrogen as a seasonal energy storage solution, you're also looking at pipeline infrastructure at least as extensive as the current natural gas system, but for hydrogen. For a complete seasonal energy solution in a 100% renewables scenario, you're looking at storage totaling 1000's of TWh. Your access to Member Features is limited.

Power to Gas technology injects hydrogen into natural gas that is transported via existing infrastructure. Buy Annual Membership → It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful. Compared with battery technologies, the lower levelized cost of the ammonia-based storage system attributes to its capability of storing energy in large quantities over a long period of time at low cost. If you're looking at "the massive amount of storage that will be required as the industry pushes to 100% renewables", no technology that's currently available is all that good. Siemens Tests Ammonia as a Form of Energy Storage for Renewables The company has opened a novel new facility to study the efficiency of converting electricity to hydrogen, and then to ammonia, and back. The energy storage market is immature, and its potential size and value is swiftly evolving. The cost-optimized system was “designed for a net discharge power of 100 MW, which meets the minimum requirement of centralized energy storage for the integration of wind energy.” It assumes that the wind farm has a capacity factor of 42% (meaning the wind isn’t blowing 58% of the time), and that the ammonia system runs “a daily storage cycle with equal charging and discharging times of 10 hours.”, Two thirds of the system cost is spent on the reversible fuel cell; the process integration is achieved with “little additional investment, while the system efficiency doubles.” In addition, because “the investment cost of the storage tanks is negligible … the economics of the ammonia-based energy storage system is hardly affected by enlarging the storage tanks for longer storage cycles,” meaning that larger systems would demonstrate significant economies of scale.
