With the global transition from fossil fuels to green energy underway, there is a need for long-term storage and long-range transmission of this green energy. Ammonia has several challenges to widespread adaption as a hydrogen storage material. 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. As such, it demonstrates what ammonia can realistically achieve in the near future, not just what it was constrained to do in the past. But to store the required amount of gaseous hydrogen, you're looking at the same options used for seasonal storage of natural gas. Ammonia is a toxic gas with a potent odor at standard temperature and pressure. 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. This is achieved through process integration: designing a system specifically for energy storage, instead of piecing together existing technologies without synergy. If there is a "green" Ammonia would the better solution be to displace the current primary use as fertilizer? Marquardt et al: Conceptual Design of Ammonia-Based Energy Storage System: System Design and Time-Invariant Performance, AIChE Journal 01/28/2017, Your email address will not be published. Until today, the energy market has been primarily focusing on two main approaches to Renewable Energy storage – rechargeable batteries and hydrogen. In the latter method, the hydrogen can then be used in hydrogen fuel cells to power devices such as electric vehicles. Another option is to use ammonia as an energy carrier. “One mole of CO2 yields only one mole of methanol using only two‐thirds of the available hydrogen. 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. 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. Instead of curtailing the excess capacity generated by renewables, this excess energy can be stored as liquid ammonia for future use by fuel cells. Producing green ammonia is intensive in terms of both energy and money, but like any operation, its costs will benefit from economy of scale, so in that way expanding in parallel both ammonia to energy and ammonia for agriculture can be mutually beneficial. Potential carriers include chemical and physical storage technologies such as metal hydrides, carbon or other nanostructures and reversible hydrocarbons. Energy efficiency is only a little worse than it is for gaseous hydrogen. As it heats it changes from its initial form of the molecule norbornadiene into its heat-trapping isomer, quadricyclane. 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. 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. 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. Actually, Ammonia IS a better energy storage option than hydrogen. The low population density allows only little energy storage and electricity export is difficult due to the isolated location. There is an existing distribution network, in which ammonia is stored in large refrigerated tanks and transported around the world by pipes, road tankers and ships. First, the reversible fuel cell must become proven: “The development of the RSOFC is still in an early stage. Most important, in my opinion, is that ammonia offers a more viable evolutionary path for business development. Some issues are yet to be discussed and resolved at Government level. 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. Nitrogen gas and water are enough to make the gas. Ammonia itself isn’t exactly cheap, if you adjust for its energy content. Isn't there still an application for energy stored via ammonia that isn't being the sole source of energy backup for the entire grid? Marquardt et al: Conceptual Design of Ammonia-Based Energy Storage System: System Design and Time-Invariant Performance, AIChE Journal 01/28/2017. Seasonal supplies of ammonia can easily be stored in mildly pressurized and widely distributed above-ground tanks. While the use of ammonia as a storage medium is indeed very interesting and plausible, it's hard to fathom it meeting the needs of the massive amount of storage that will be required as the industry pushes to 100% renewables. Buy Annual Membership → Grader et al: Nitrogen‐Based Fuels: A Power‐to‐Fuel‐to‐Power Analysis, Angewandte Chemie, 07/25/2016. Today these fuel cells run on industrially produced ammonia, mainly produced via the commonly used but highly pollutant Haber-Bosch process. And when ammonia is cracked to produce hydrogen, no harmful pollutants are emitted. 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. “It is less explosive, requires less complex storage and transport solutions, and it is a well-known commodity from industry. 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. Annual global produ… Ammonia is well-suited for both applications, in that at room temperature liquid ammonia is a highly efficient carrier of hydrogen that can be readily transported. Wind energy is produced only when the wind blows. 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. The storage capacity of energy as hydrogen is far higher than that of batteries. 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. There are over 800 retail NH3 distribution facilities in Iowa alone. Click to enlarge. Hydrogen & Offshore Wind, business advisor and trainer. So unless one figures out a way to use it all, its application is primarily suited for small scale storage projects. “The investment cost share of the storage tanks increases only by 3% from a daily to a weekly storage cycle, which corresponds to an increase in the levelized cost of merely 0.01 $/kWh.”. The ammonia-assisted renewable energy system satisfies specific power (and possibly ammonia) demands. 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. Mandatory Backup Power for Cell Towers in California: How Can Californians Enjoy Uninterrupted Service, Power Resilience and Clean Air? Rocket engines have also been fueled by ammonia. Excel file, updated quarterly. It is indeed a cruel irony to think that PG&E in California - thought of by many as one of the most sustainable and progressive geographies in terms of renewable energy - home of high ratios of residential solar and EVs - is in fact now installing thousands of temporary diesel generators for backup power during planned shutdowns they must carry out for wildfire prevention... certainly with better planning hybrid solutions incorporating renewables and innovative energy storage technologies - leveraging ammonia and fuel cells to complement intermittent solar or wind and batteries - would be a far wiser investment for the long-term and for protecting the environment. Energy Storage with Anhydrous Ammonia: Comparison with other Energy Storage Ammonia: The Key to US Energy Independence 29 – 30 September, Minneapolis Rev: 8 Oct 08 Bill Leighty, Director The Leighty Foundation Juneau, AK wleighty@earthlink.net 907-586-1426 206-719-5554 cell 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.”. The energy density for ammonia is 11.5 MJ/l, gasoline is 34.2. A coupled refrigeration cycle is utilized to recycle nitrogen completely. 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. With climate change causing more frequent extreme weather and the IPCC setting targets to reduce emissions to prevent a temperature rise of another 1.5 degrees, the world is making efforts to transition to Renewable Energy. 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. Get the monthly newsletter. And when ammonia is cracked to produce hydrogen, no harmful pollutants are emitted. Design and optimization of an ammonia synthesis system for ammonia-based solar thermochemical energy storage, Solar Energy (2017). 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. It won't be easy to get there. Ammonia has the lowest required energy for feedstock separation, even when compared to carbon‐based fuels in the case of flue‐gas‐derived CO2. The reaction products are stored, and when energy is needed, it can be recovered as heat given off by an exothermic reactor that reconstitutes the original reactants. However, in order to release hydrogen from ammonia, significant energy input as well as reactor mass and volume are required. 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. This report addresses the techno-economics of an ammonia-based energy storage system (ESS) integrated with renewable electricity generation on an island system (a power network which is not connected to the grid). Attacking Carbon Pollution: It’s Transportation’s Turn. Ammonia (NH 3) is a chemical compound made up of one nitrogen atom and three hydrogen atoms. Those are long duration backup capability for facilities that require uninterruptable power, and reliable power to remote facilities. Marquardt et al: Conceptual Design of Ammonia-Based Energy Storage System: System Design and Time-Invariant Performance, AIChE Journal 01/28/2017. You need to be a member of Energy Central to access some features and content. One interesting method to deliver hydrogen involves hydriding a chemical compound at the site of production and then dehydriding it at the point of delivery or within a fuel cell. Methane has four carbon-hydrogen bonds that can be broken to release energy and ammonia has three nitrogen-hydrogen bonds that can be broken to release energy (Figure 3). Instead of curtailing the excess capacity generated by renewables, this excess energy can be stored as liquid ammonia for future use by fuel cells. Power to Gas technology injects hydrogen into natural gas that is transported via existing infrastructure. The advantages are many. Because this equation includes no carbon, when matured, this technology will allow us to have 100% green distributed power generation. there are a ton of studies and a few demonstration projects that have already shown this - www.nh3fuelassociation.org share | cite | improve this answer | follow | 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. Not yet. But there is another way to produce carbon-free fuel: ammonia. More information: Chen Chen et al. The energy storage properties of ammonia are fundamentally similar to those of methane. 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 vapor pressure of liquid ammonia is similar to propane. For more information, contact us at team@gencellenergy.com. 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. So far, we thought the cheapest way to store large amounts of energy was power-to-gas. Your email address will not be published. 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. Other approaches involve pumping hydrogen into underground caverns, many of which were created by mining activities, where it is stored safely. Click to enlarge. 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. The power plant will be transformed to a mega battery to store excess green power from wind energy. Learn about membership →. Hydrogen delivery is constrained by high costs, energy efficiency losses in transit, hydrogen purity issues and propensity for leakage. Another key advantage is ammonia’s chemical compatibility with alkaline fuel cells which use an alkaline electrolyte. From Black & Veatch's recently release Hybrid LNG & Ammonia Infrastructure: Key to a Green Economy eBook, this section discusses the optimum conversion of existing LNG storage tanks to ammonia storage … (Part I), Energy Storage in the Grid: The Holy Grail? And the pure oxygen stream produced by water-splitting is reused to power the fuel cell. Building a viable hydrogen infrastructure for delivery from production to consumption sites is not a simple matter. The heat of formation of ammonia is 30.6kJ/molH2. Start a Post » Learn more about posting on Energy Central ». 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. Your access to Member Features is limited. As the paper states, “the geographical site of a wind park does often not offer the favorable conditions for a pumped hydro or compressed air energy storage system,” because these require major physical attributes like a nearby reservoir or underground cavern. Mass, centralized hydrogen production, whether as gas or liquid, entails high delivery and distribution costs, while low-volume distributed production is prohibitively costly. Under such conditions, less energy is required to produce ammonia, resulting in higher energy efficiency for energy storage. Except where otherwise noted, content on this website is licensed under a Creative Commons Attribution 4.0 International License. A Key To The ‘Hydrogen Economy’ Is Carbon-Free Ammonia, Resilient Independent DERs Can Stabilize a Volatile Climate and Energy Economy, Learn more about posting on Energy Central », ‘Buy Clean’ policies have promise, but we first need to know which products are low-carbon. Ammonia could be a useful method of energy storage and transport that has the potential to be carbon-free in the right conditions. The process is conducted at a pressure of 200 atm and high reaction temperatures of nearly 500°C. For this to be viable, an ammonia-based energy storage system must display “High round-trip efficiency, low cost and considerable flexibility.” Maximizing efficiency – or minimizing the losses from converting power to ammonia and then back to power – is the major advancement revealed by the German paper. Standby diesel generators need to be run for a few hours every month to turn over their fuel supply. The 3-step process is as followed: 1. Read more: Mandatory Backup Power for Cell Towers in California: How Can Californians Enjoy Uninterrupted Service, Power Resilience and Clean Air? There are claims that the Haber-Bosch process is one of the largest contributors to a build-up of reactive nitrogen in the biosphere. 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 reason is because energy storage as hydrogen is challenging. So says Jack Robertson about the prospects for making ammonia the world’s go-to liquid fuel and renewable energy storage medium. 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. 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. 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. 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. Similar to hydrogen, ammonia is being considered for its potential to directly power combustion without any CO2 emissions. Please sign-in or register to continue. High availability fuel cells can be an important component of these solutions. Energy storage – ammonia is easily stored in bulk as a liquid at modest pressures (10-15 bar) or refrigerated to -33°C. 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. Availability – the second most widely produced chemical in the world, 200 million tons of ammonia are produced per year. Ammonia plant cost comparisons: Natural gas, Coal, or Electrolysis? 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. Extensive deployment of heat exchangers throughout the system, especially between the fuel cell and the Haber-Bosch reactor, reduces the overall power requirements. Fundamental issues, such as cell fabrication methods and reversible operation, still require further research.”. A centralized database where products have embedded emissions verified and listed, similar to a nutritional label, would absolutely be a gamechanger. A natural growth path for ammonia + fuel cells would be for backup supply to microgrids of the sort being set up to serve communities likely to be affected by public safety power shutoffs in fire-prone areas.
