Electrified ammonia production as a commodity and energy storage medium to connect the food, energy

If ammonia is only used as an energy storage medium, a positive revenue of US$15.3 million will be obtained, which is still US$258 million lower than electricity export. Yet this difference might be compensated by the benefits of large-scale ammonia energy storage on the grid ( Dowling et al., 2020 ; Hunter et al., 2021 ).

Energies | Free Full-Text | Operation Optimization of Steam Accumulators as Thermal Energy Storage

Although steam is widely used in industrial production, there is often an imbalance between steam supply and demand, which ultimately results in steam waste. To solve this problem, steam accumulators (SAs) can be used as thermal energy storage and buffer units. However, it is difficult to promote the application of SAs due to high investment costs,

Figure 5.7 shows the volume-specific thermal energy q (h 0) provided by steam accumulators operated with starting pressures between 2 and 10 bar. This requires the definition of a reference enthalpy, which is defined here as h 0 = 0 kJ/kg, so it is assumed that the steam condenses and cools to 0 °C after extraction.
