Nowadays, there is an increase in the installed capacity of solar (mainly) and wind energy, which requires additional balancing reserves and requires the improvement of existing and development of new balancing methods. If at the end of 2018 the total capacity of PV and WPP was 1.7 GW (excluding the occupied territories), then at the end of 2020 it increased to 8 GW (including PV of households). Thus, the simultaneous influence of two reinforcing factors affected – a decrease in available control volumes at TPPs and an increase in the need for shunting generation due to increasing uneven daily consumption schedule and increasing volumes of stochastic generation from RES, namely unsecured power stations – PV and WPP. As a result, this created a problem of shortage of shunting generation and led to the need to build new high-shunting capacity, such as using hydrogen technology. Therefore, the article analyzes the problems of electricity that can be solved through the use of hydrogen technologies. The preconditions of occurrence of these problems are investigated and the ways of their overcoming are offered. Many developed countries, such as the United States and China, have a positive experience of using hydrogen technology as a source of electricity. Ukraine has adopted a Roadmap for the development of hydrogen energy for the period up to 2035 to ensure the use of hydrogen as an environmentally friendly energy source. Therefore, the article discusses in detail the methods of obtaining hydrogen fuel. The variety of methods for producing hydrogen is one of the main advantages of hydrogen energy, as it increases energy security and reduces dependence on certain types of raw materials. These include: steam conversion of methane and natural gas, coal gasification, water electrolysis, pyrolysis, partial oxidation, biotechnology. The article proposes a schematic diagram of a combined power plant of low power, containing a battery of fuel cells, wind turbine, cell, receiver. This installation can be used as an autonomous power source.

“…Palys and Daoutidis investigate the use of hydrogen and ammonia for energy storage at 15 locations that represent different climate regions throughout the U.S. Their results show that the best strategy is to combine the use of hydrogen for short-term and ammonia for long-term energy storage. In another example, Demirhan et al consider producing green ammonia in Texas and transporting it to New York to supplement its local renewable energy generation, which can lead to up to 70% reduction in energy costs. Palys et al further demonstrate the versatility of green ammonia by proposing the concept of an integrated energy and agriculture system that utilizes ammonia as fertilizer, as fuel for tractors and grain drying, and to meet local electricity demand.…”

Offshore wind is playing an increasingly important role in our energy mix as it provides the opportunity to increase the penetration of wind energy considerably beyond the current capacity of land-based wind resources. While most planned offshore wind projects consider constructing the wind farms relatively close to the coast, there is vast untapped potential over the open ocean where wind velocities are significantly higher. However, transmitting electricity generated far from shore to onshore demand points is a major challenge since using submarine power cables for long distances can be prohibitively expensive. To address this challenge, we consider using offshore wind energy to directly produce green ammonia that can then be transported to shore via ships or pipelines. This is technically feasible since electricity-based production of ammonia only requires water and air as input materials. We perform a comprehensive techno-economic analysis for such green offshore ammonia plants, determining the minimum achievable levelized costs of ammonia for various wind profiles, plant capacities, distances to shore, and water depths. Our results indicate that the proposed approach has the promise to be cost-competitive, especially when considering expected cost reductions in offshore wind turbines in the foreseeable future.

As the basis for virtually any form of nitrogen fertilizers, ammonia plays a vital role in agriculture; in addition, there has been an increased interest in its use as a carbon-free energy carrier. However, ammonia is also associated with two major environmental concerns: CO 2 emissions from the conventional production process and nitrogen pollution from the excessive use of ammoniabased fertilizers. To mitigate these environmental impacts, we develop an optimization framework for the design of a sustainable ammonia-based agricultural system that synergistically integrates the production of ammonia from renewable resources and effective measures for nitrogen management. The proposed model captures the effect of intermittency by incorporating both design and detailed operational decisions. By applying a multiscale time representation that reduces the problem size and a tailored surrogate model that accurately approximates model nonlinearity, we are able to achieve optimal solutions within reasonable computation times. A computational case study is conducted using real-world data from a local farm in Morris, Minnesota, and the results indicate the trade-off between cost and nitrogen loss. Importantly, we show that practicing effective nitrogen management can significantly reduce the nitrogen loss with only a small increase in net present cost.
