ELECTROLYTIC HYDROGEN : A FUTURE TECHNOLOGY FOR ENERGY STORAG
Post: #1

In the future, predominantly solar or wind power systems will likely require energy storage for days to approximately a week, with or without connections to the 2 electric grid. If so, conversion of electricity to chemical energy is potentially attractive, since chemicals are inexpensive to store and turnaround efficiency is less critical for storage periods of a week or more. The most attractive chemical for this process is likely to be hydrogen (H2) generated locally by electrolysis of water using intermittent excess solar or wind power. Later, when combined with air or oxygen (O2) in engines or fuel cells, H2 can regenerate electricity on demand. Although H2 electricity storage is less energy efficient (40-50%) than compressed air storage, H2 has far lower costs of storage capacity, since H2 is a chemical fuel and air is not. For example, a 250-liter pressure vessel designed to store 10-20 kWh of compressed air could store enough H2 to provide 150-300 kWh of electricity, reducing the cost of storage capacity by more than a factor of 10. H2 energy storage is therefore economically best suited to situations where the total amount of energy stored is more valuable than efficiency. This should be the case for electricity stored longer than 1-2 days. H2 may also be stored cheaply without high pressure as a very low temperature (-453 oF) liquid (LH2) or by absorption in powders of abundant metals (e.g. iron, titanium, aluminum, and sodium) that release H2 upon moderate heating (<200 oF).

renewable energy technologies concept requires the integration of two sub-systems or components.
The first is a hydrogen/bromine regenerative electrochemical cell that is well-suited for energy
storage applications such as peak shaving, load management and other emerging distributed utility
applications. regenerative hydrogen/bromine cell facilitates electrical energy storage by
consuming electricity in electrolyzing hydrogen bromide into hydrogen and bromine reactants as
stored chemical energy. The hydrogen and bromine are later reacted electrochemically in the cell to
produce electrical energy. Hence, the cell is regenerative (reversible), in that it can efficiently
operate as an electrolysis cell producing reactants and consuming electricity or as a fuel cell
consuming reactants and producing electricity. In effect, the cell operates as a battery, exchanging
electrical and chemical energy, with one difference: the reactants are stored outside of the cell as
opposed to a battery where the reactants are inside. Therefore, to increase capacity (kWh) it is only
necessary to add more reactants rather than more batteries.
This electrochemical cell technology
to reduce the nations dependence on oil-fueled power generation. Technologies has developed an industrial-scale, brominebased
regenerative cell for electric utility energy storage. The Innogy cell has been designed for
high-volume, low-cost manufacturing and will be adapted for service in the system.
The second component is a chemical reactor that thermochemically produces hydrogen bromide
(HBr) and carbon dioxide (CO2) from water (H2O), natural gas (CH4) and bromine (Br2). The
regenerative cell and chemical reactor integrated in a system produces hydrogen and stores
electrical energy.
