1 Pumped Heat Electricity Storage: Potential Analysis and ORC Requirements Institute of Combustion and Gas Dynamics Chair of Thermodynamics Dennis Roskosch, Burak Atakan ASME ORC 2017 Milano September 15, 2017 Roskosch et al. ASME ORC 2017 September 15,
2 Motivation Rising share of renewable energy sources in power generation Increasing fluctuations within the electrical grid Source: Large scale energy storage problem Source: Badische Zeitung Roskosch et al. ASME ORC 2017 September 15,
3 Pumped heat electricity storage (PHES) charging cycle: storage T st = vapor compression heat pump What discharging is the cycle: Q Q H organic-rankine-cycle H storage: theoretical W latent potential? or sensible heat HP ORC W Q L Q L storage efficiency / roundtrip efficiency surroundings T sur = T L Ψ = W W = COP HP η ORC Roskosch et al. ASME ORC 2017 September 15,
4 Pre-studies: models Combining two full Carnot-cycles: leads always to Ψ = 1 Work of Thess 1 : Carnot-cycles with irreversible heat transfer maximum power output (ORC) Work of Roskosch and Atakan 2 : Power output and efficiency lead to Pareto frontier requiring 80 % of maximum power is a good compromise UA HP Rankine-cycles.

ASME ORC 2017 September 15,
5 Transfer to Rankine-cycles Process temperatures from pre-study U PC = 10 U SP Heat pump & ORC full evaporation, condensation ideal compressor and expander For heat pump also expansion: throttle or expander Now: Fluid properties get important How to select? Inverse-Engineering-approach Roskosch et al. ASME ORC 2017 September 15,
6 Inverse-Engineering of fluid parameters Optimization algorithm X X X, Z Constraints Variable domains Ψ Process Fluid property model X opt Fluid property model Peng-Robinson EOS ideal gas heat capacity X=[T c, p c, ω, c p,0, dc p /dt] Constraints Realistic range for every parameter 0.05 Mpa p sys 5 Mpa no condensation in expander (ORC) and compressor (heat pump) Roskosch et al. ASME ORC 2017 September 15,
7 Why using optimal fluid parameters? Evaluation of promising operating and boundary conditions without the influence of a specific fluid better comparability of the result (e.g. storage temperature) finding limits in operating conditions with respect to available chemical compounds I need: T c = 1100 C p c = 3 Mpa ω = 0.01 c p = Such a substance doesn t exist! Roskosch et al. ASME ORC 2017 September 15,
8 Results: efficiency and power output Roskosch et al. ASME ORC 2017 September 15,
9 Results: efficiency and power output Roskosch et al. ASME ORC 2017 September 15,
10 Results: efficiency and power output Roskosch et al. ASME ORC 2017 September 15,
11 Influence of superheating Common heat sources: Superheating improves η ORC What about Ψ? Modelling and boundary conditions: based on previous study (Rankine-cycle): T i, U i etc. storage temperature 400 K fixed power output: Value without superheating fluid is again optimimized for every superheating temperature minumum pinch-temperature of 5 K: higher superheatings only if evaporation temperature is decreased Roskosch et al. ASME ORC 2017 September 15,
12 Influence of superheating: Results Constant evaporation temperature: Ψ increases slightly heat transfer area increases stronger Reduced evaporation temperature: Ψ decreases Superheating is not useful! Roskosch et al. ASME ORC 2017 September 15,
13 Conclusions PHES is a promising application of an ORC and worth further investigations Carnot-cycles were transferred to Rankine-cycles using optimal fluids Contrary to Carnot-cycles: Ψ decreases with increasing T storage Expansion of the heat pump boiling of the fluid (ORC) Superheating at expander inlet is not useful Above T st = 430 K multistage cycles are probably needed Roskosch et al. ASME ORC 2017 September 15,
14 Outlook Expander instead of throttle in heat pump? Fluid boiling in ORC: Regenerative feed water heater? Influence of irreversibilities of the different components identifying efficient real fluids sensible heat storages storage modelling Roskosch et al. ASME ORC 2017 September 15,
15 Thank You! Roskosch et al. ASME ORC 2017 September 15,
16 Full Carnot-cycles: Ψ=1 W Q H Q L PHES (T st >T sur ) storage T st = HP ORC Q H Q L surrounding T sur = T L W storage efficiency / roundtrip efficiency Ψ = W W combining two Carnot-cycles Ψ = W W = η ORC Q H Ψ = T L not really helpful! Q H ϵ HP c = η ORC T L = 1 c ε HP Roskosch et al. ASME ORC 2017 September 15,
17 Reduced power cycle (pre-study) Boundary conditions t charging = t discharging. Same thermal resistances R L = R L R H = R H. R H T H T st R H T - H HP ORC P = Q H η ORC = (T st T H ) 1 T L R H R L T L - Ψ PHES = ε HP η ORC = T L 1 T L R L T L T sur Q H = Q L T L Q H = Q L T L T st = T st Roskosch et al. ASME ORC 2017 September 15,
18 Pre-studies: results UA UA - T st HP ORC UA T L UA T L - T sur Boundary conditions t charging = t discharging, all heatexchangers: A = 4 m² U = 1000 Wm -2 K -1 Roskosch et al. ASME ORC 2017 September 15,

This follows from the Clausius inequality as a consequence of the second law of thermodynamics. Therefore. (for reversible process only) (22.
Entropy Clausius inequality can be used to analyze the cyclic process in a quantitative manner. The second law became a law of wider applicability when Clausius introduced the property called entropy.
The exergy of asystemis the maximum useful work possible during a process that brings the system into equilibrium with aheat reservoir. (4.
