Description
BIOELECTROCHEMICAL ENERGY STORAGE DEVICE AND METHOD FOR BIOELECTROCHEMICAL ENERGY STORAGE
The present invention relates to a device for bioelectrochemical storage of energy, with the device being capable of charging and discharging energy.
Temporarily storage of energy is important to enable storage of energy in a time period of an energy surplus and to enable providing additional energy in a time period of a high energy demand. Examples of energy storage include storing wind energy in water (level) buffers, for example. Another conventional example of such energy storage devices are (car) batteries. This is not a very sustainable approach considering the materials required for the batteries.
These conventional devices and systems do not provide an effective energy storage device that is sustainable and could be implemented on a wide scale, for example including house holds.
The use of bioelectrochemical devices is known for being capable of oxidizing carbohydrates anaerobically to carbon dioxide involving anode respiring biofilms (ARBs) that can be used in microbial fuel cells (MFCs) and microbial electrolysis cells (MECs). These devices are not capable of storing (external) energy.
The present invention has for its object to provide an energy storage device, more particularly a bioelectrochemical energy storage device, capable of energy storage in time periods of an energy surplus and energy discharge in time periods of energy shortage.
This objective is achieved with the bioelectrochemical energy storage device according to the invention, the device comprising: - a housing having a first compartment and a second compartment; - a reversible bio-electrode that is placed in the first compartment and comprises a microbial biosystem capable of performing in a charging state a charging operation involving a reduction reaction converting electrical energy into chemical energy, and performing in a discharging state a discharching operation involving an oxidation reaction converting chemical energy into electrical energy; and - a counter electrode that is placed in the second compartment and is electrically connectable in a circuit with the reversible bio-electrode.
The device according to the invention comprises a first and a second compartment. The first compartment is provided with a reversible bio-electrode. A counter electrode is placed in the second compartment. By providing a circuit the reversible bio-electrode and the counter electrode can be electrically connected. In a charging state of the device this circuit enables providing electrons at the reversible bio-electrode to perform a reduction reaction. For example, the reduction reaction may convert CO2 electrochemically into organic molecules like methane and volatile fatty acids. Also, a combined electrochemical and biological reduction reaction/process is possible. For example, an electrochemical conversion into hydrogen that in a biological conversion is converted with bicarbonate into acetate is capable of storing energy in accordance with the present invention. This embodiment enables providing the biomass independent of the electrode and in stead thereof, or in addition thereto, providing the biomass in the suspension using the dissolved components. This electrode with suspended biomass provides a reversible bio-electrode in a system configuration. The bio-electrode in the system according to the invention also comprises such bioelectrode system. In fact, in the different embodiments of the invention electrical energy is converted into chemical energy, for example storing the electrical energy in organic molecules.
In a discharging state of the device organic molecules can be oxidized to C02, protons, and electrons that can be transferred by the circuit, for example.
Therefore, the device according to the invention stores electrical energy by converting electrical energy into chemical energy and produces energy by converting chemical energy into electrical energy. This enables the bioelectrochemical energy storage device to act as a biobattery capable of storing and producing energy. More specifically, the storage of energy in a bioelectrochemical energy storage device according to the present invention enables higher specific energy densities and prolonged charge/discharge periods as compared to alternative conventional systems including capacitive systems.
As a further advantage the device according to the present invention provides an energy storage that is more safe and more cost effective as compared to many conventional devices. In addition, the device according to the invention can be regenerated, thereby enabling an effective use of the device under practical conditions. Furthermore, the device according to the invention is capable of being provided as a stand-alone application, in other words as an off-grid application, thereby also enabling effective energy storage in remote areas, for example.
The oxidation and reduction reactions are preferably performed with the use of electroactive biofilms (EABs) that interact with conductive surfaces of an electrode and catalyse reduction and/or oxidation reactions as part of the metabolism. In the discharging and/or charging states different components may react in the oxidation and reduction reactions including organic and anorganic components. For example, anodes respiring biofilms (ARBs) are capable to oxidize carbohydrates anaerobically with the conductive material in the electrode as electron acceptor. In the discharging reaction, with the reversible bio-electrode(s) being connected to a counter electrode, electrical power can be obtained. Charge neutrality is being maintained with the use of ionic exchange, for example.
The reversible bio electrode is preferably made of a biocompatible material to enable microorganisms to catalyze the reactions. The electrodes preferably have a sufficiently high electric conductivity. Possible materials include graphite, carbon, titanium etcetera. Optionally, additional use is made of a catalyst for conversion of C02 to organic material.
The counter electrode should be capable to switch between the different states. The counter electrode preferably comprises a material with a high capacity and/or a large surface area that cooperates with an electrolyte solution in the compartment. For example, the counter electrode may comprise Mn having Na+ as counter ion. The use of other materials in the device according to the invention could also be envisaged. Alternatively, or in addition, a suitable reversible biological reaction can be performed at the counter electrode when the device according to the invention is in use.
Both electrodes should preferably be anodic and cathodic stable such that the electrodes do not react at the potential that is applied in the charging and/or discharging state of the bioelectrochemical energy storage device.
In a presently preferred embodiment of the invention oxidation and reduction of acetate is performed. In addition, or alternatively, butyrate, propionate and other components can be applied. In principle organic components can be used provided that they can be reversibly produced. Optionally, other processes, such as hydrolyses and fermentation, are used to convert longer chains into for example acetate that can be oxidized to electrons.
In the oxidation of an organic substrate a large amount of acid can be produced. For example, if acetate is oxidized, every mole of acetate produces 8 moles of protons that could significantly change the pFI of the system. Preferably, buffer capacity in the system should be sufficiently high to compensate for the acid production, and/or compensation should be provided by adding or generating alkalinity, and/or by ion transport of protons through the membrane. In addition, or as an alternative thereto, extremophiles can be used on the reversible bio-electrodes that are capable of dealing with these pH changes.
It will be understood that the device according to the present invention may comprise more than two compartments with one or more electrodes and/or more than one electrode can be provided in one compartment. The specific configuration can be chosen dependent on required dimensions and/or amounts of energy that should be stored, for example.
Preferably, the bioelectrochemical energy storage device comprises an ion-exchange membrane separating the first and second compartment.
By providing an ion-exchange membrane charge neutrality in the housing is maintained by ionic exchange through the membrane. The ion-exchange membrane may comprise an anionic exchange membrane, a cation exchange membrane and/or a bipolar membrane comprising a cation and anion layer, for example. The use of such membrane provides an effective means to achieve charge neutrality in the housing and enable electricity generation in the discharging state and storage of chemical energy in a charging state of the bioelectrochemical energy storage device. For example, when applying acetate in the device according to the invention, the membrane is preferably a proton selective membrane to enhance the aforementioned compensating effect.
To enable transport of charge in the compartments an appropriate electrolyte is preferably applied in the compartment. For example, in a presently preferred embodiment of the invention the second compartment with the counter electrode is provided with Fe3+/Fe2+, Cu2+/Cu, and/or Ag/AgCl.
In a presently preferred embodiment according to the invention the counter electrode comprises a capacitive electrode.
By providing a capacitive electrode a relatively simple counter electrode is achieved with a sufficient capacity. Preferably, the capacitive counter electrode is chosen in relation to the specific electrolyte composition in the second compartment. In such embodiment ions of the electrolyte may achieve a so-called double layer providing an overall capacity of the capacitive counter electrode.
In a presently preferred embodiment the first compartment comprises an organic material input.
By providing an organic material input organic material can be supplied to the first compartment. This enables increasing the capacity of the bioelectrochemical energy storage device during use and/or enables regeneration of the relevant components in the first compartment of the bioelectrochemical energy storage device. In one of the presently preferred embodiments the organic material comprises carbohydrates. It will be understood that other organic material could also be used in the system according to the invention, for example including protein and/of fats.
In a presently preferred embodiment according to the present invention the microbial biosystem comprises a unitary biosystem capable of performing both the oxidation and reduction reactions.
By providing a unitary biosystem it is possible to perform both the oxidation and reduction reactions in the charging and discharging state of the energy storing device. This has the advantage that only one biosystem is required.
In a further presently preferred embodiment according to the present invention the microbial biosystem comprises a multiple biosystem with a first bio-subsystem capable of performing the oxidation reaction and a second bio-subsystem, at least partly different from the first bio-subsystem, capable of performing the reduction reaction.
By providing at least two bio-subsystems the oxidation reaction and the reduction reactions can be optimized using specific microbial sub-systems that are dedicated to either the oxidation reaction or the reduction reaction. This optimizes the overall performance of the bioelectrochemical energy storage device according to the present invention.
In a further presently preferred embodiment according to the present invention the device is configured to store above 10 kWh/m3, more preferably above 12.5 kWh/m3, and most preferably above 15 kWh/m3.
By providing a storage device capable of storing energy at a energy density of preferably above 15 kWh/m3 an effective and efficient storage is provided. In one of the presently preferred embodiments according to the invention use is made of acetate in the device. In a device according to such preferred embodiment efficient energy storage is enabled with a biological conversion rate of acetate to electrons of about 25 A/m2.
In a further presently preferred embodiment according to the present invention the first and/or second compartments are separated into an oxidation sub-compartment and a reduction subcompartment.
By separating the consumption and production of electrons in different sub-compartments, including different (sub)-reactors, undesired competition of both reactions is prevented. Preferably, electrolyte is circulated over the sub-compartments.
The invention further relates to a method for hioelectrochemical energy storage, the method comprising the steps of: - providing a bioelectrochemical energy storage device as mentioned above; - performing a charging operation by providing electrons to the reversible bio-electrode to perform a reduction operation and converting electrical energy into chemical energy; and - performing a discharging operation by extracting electrons from the reversible bioelectrode to perform an oxidation reaction and converting chemical energy into electrical energy.
The method provides the same effects and advantages as described for the device. The method enables storage of energy in a charging state, more specifically storage of energy as chemical energy in a time period of an energy surplus, and providing electrical energy in a discharging state by converting (chemical) components in a time period of energy shortage. This provides an effective means to store energy.
In a presently preferred embodiment the charging and discharging operations are performed under anaerobic conditions. This enables the use of anaerobic microorganisms in the anaerobic biosystem and/or bio-subsystems.
Preferably, the first compartment is provided with carbohydrates capable of anaerobic oxidation for converting chemical energy into electrical energy. It was shown that the use of carbohydrates enables an efficient storage of energy. Preferably, acetate is provided to the first compartment enabling efficient charging and discharging of the device. It will be understood that other components, preferably other organic material, can also be applied as mentioned in relation to the device.
In a presently preferred embodiment the method comprises the additional step of providing a first compartment with organic material to add additional energy to the system and/or recharge the system. This provides an effective means to increase the overall capacity of the system and/or recharge or regenerate the system when in use. In a presently preferred embodiment, for recharging the system use is made of ethanol, including the use of bio-ethanol.
Preferably, the method is performed to enable local semi-off-grid or local off-grid energy storage without being dependent on the electricity grid. This provides a method and device capable of acting as a stand-alone device under a wide range of circumstances, including any household applications.
