6 FAQs about [Steam-to-Liquid Pressure Conversion Energy Storage Power Generation]

Does a direct steam generation solar power plant have integrated thermal storage?

A direct steam generation solar power plant with integrated thermal storage. J. Solar Energy Eng. Transac. 132, 0310141–0310145. doi: 10.1115/1.4001563 Birnbaum, J., Feldhoff, J. F., Fichtner, M., Hirsch, T., Jöcker, M., Pitz-Paal, R., et al. (2011). Steam temperature stability in a direct steam generation solar power plant.

What is direct steam generation?

Compared to conventional concentrated solar power systems, which use synthetic oils or molten salts as the heat transfer fluid, direct steam generation offers an opportunity to achieve higher steam temperatures in the Rankine power cycle and to reduce parasitic losses, thereby enabling improved thermal efficiencies.

What happens during thermal processes in direct steam generation systems?

Of interest are the flow regimes, heat transfer coefficients and pressure drops that are experienced during the thermal processes present in direct steam generation systems, including those occurring in the solar collectors, evaporators, condensers and relevant energy storage schemes during thermal charging and discharging.

Does steam pressure affect levelized cost of storage?

The effect of the initial steam pressure in the SA (7.0–10.0 MPa) on the steam-discharge profile and levelized cost of storage (LCOS) was investigated for the case of a power increment of 500 kW e (25 %) and 4-h discharge per day. In addition, the influence of the capacity on the LCOS was investigated from 5 % to 30 %.

How does a steam turbine work?

Steam passes through pressure-reducing valves (PRVs, also known as letdown valves) at various locations in the steam distribution system to let down or reduce its pressure. A noncondensing or backpressure steam turbine can perform the same pressure-reducing function as a PRV while converting steam energy into electrical energy.

Is a steam accumulator a sensible heat-storage unit for the Carnot-battery system?

In this study, a steam accumulator (SA), which is a sensible heat-storage unit for the Carnot-battery system, was integrated with the existing steam Rankine cycle of a biomass power plant (2000 kW e, inlet steam temperature and pressure of 480 °C and 6.3 MPa, respectively).
