Gas Tank Energy Storage (GTES)

The gas tank energy storage is an energy storage device that stores gas.

Attribute	Unit	Data type	Description
deployment	–	bool	If set to ‘true’, the technology will be considered in the energy system model (this does not necessarily mean it will be used). Only relevant for optimisation.
force_asynchronous_prod_con	–	bool	If set to ‘true’, the storage cannot be charged and discharged simultaneously
eta_chg_dchg	–	float	Charging and discharging efficiency (fixed). Roundtrip-efficiency is calculated as eta_chg_dchg*eta_chg_dchg.
gtes_gamma	1/timestep	float	Loss rate: fraction of gas lost during one timestep (e.g. 1 hour)
capacity_kWh	kWh	str	Storage capacity.
chg_dchg_per_cap_max	1/timestep	float	Max. charge/discharge (kW) per storage cap (kWh) per timestep.
initial_charge	–	float	Initial charge of gas tank (fraction of total storage capacity)
optimized_initial_charge	–	bool
co2_intensity	kg CO2/kWh	float	Carbon-dioxide intensity of technology output (annual average value).
lifetime	years	int	Expected lifetime of technology before replacement is required.
interest_rate	–	float	Interest rate for computing levelised costs (if required).
capex	CHF/kWh	float	CAPEX cost of technology per unit of capacity.
maintenance_cost	CHF/kWh/year	float	OPEX of the technology
