"Absent battery storage, the whole value proposition of intermittent renewable energy makes no sense at all" - MIT - Massachusetts Institute of Technology. Renewable energy is the cornerstone of humankind’s urgent endeavor to address the climate change challenge.

Storing energy in the form of heat could be cheaper than any other form of energy storage that exists!

Energize the Future, CSPU Hydride Battery technology will provide a much-needed advancement in a market estimated to be $40 billion by 2025. Metal Hydride Based Thermochemical Super Batteries offer an enormous billion dollar global market, Electric Power Plants, Solar/Wind Power.

CSPU has developed a highly-engineered Metal Hydride battery which is an improved, new way of storing electricity in the form of heat. This enables solar energy systems to generate electricity 24 hours a day.

Thermal energy is transformed into chemical energy. Thermochemical energy, offers a higher amount of energy stored per mass of storage material. The special feature of metal hydrides as reversible heat storage systems is that upon their thermal dissociation the liberated hydrogen is simultaneously a fuel with the highest known gravimetric energy density.

Thermal Battery Demonstration

Low-Cost, High-Temperature, Highenergy Density Thermal Energy Storage Systems

There is a critical need to find efficient, cost-effective thermal energy storage solutions to maximize the use of domestic solar and energy resources. The real future opportunities for investment in the energy sector are renewables. Most utility-scale solar power plants only run at about 25% of their capacity because they can't generate power at night-thermal energy storage makes it possible to increase this capacity to up to 60-75%. Similarly, power plants produce a constant output of power--thermal energy storage could help increase this output during times of critical peak demand. Therefore saving utility companies billions of dollars.

The ability to store thermal energy cheaply and easily allows the reliable generation of output power.

Hydrogen storage systems offer the highest energy storage capacity per volume. Enhance Performance Metal-Hydride Chemical-Energy Storage Systems will be used to ‘Close the Energy Loop’ - Energy Reserve. The higher the battery's capacity, the more Solar Energy can be stored. Hydride Batteries storage systems can also help reduce the amount of electricity utilities use during grid peak periods.

The deployment of a cost-effective energy storage system using thermal batteries will revolutionise the landscape of renewable energy production world-wide by allowing renewables to truly compete with fossil fuels.

Wind and solar power generation is expanding around the globe at record rates, allowing more people to get their electricity from clean, renewable sources than ever before.

“Transformational” and “Disruptive” Technology

Hydride, any of a class of chemical compounds in which hydrogen is combined with another element.

Similar to the chemical reactions that make Hand Warmers heat up. Chemical storage is the technology of storing heat by utilizing highly efficient reversible alloys and hydride materials, in a chemical-reactions. It is an endothermic process, hydrogenation and dehydrogenation reactions. The principle of hydrogen storage in metal hydrides is that atoms of hydrogen under low pressure bond chemically to the metal atoms. Adsorption of H2 gas proceeds spontaneously in an exothermic process. Conversely, hydrogen can desorbed upon heating.

Metal Hydride Batteries are the one of the best High Performance Energy Storage Systems. They are very beneficial and represent a better state-of-the-art new technology. Metal hydrides, can offer several advantages over other thermochemical materials (salt hydrates, metal hydroxides, oxide, and carbonates) such as high energy storage density and power density.

Thermochemical Heat Storage - Reversible Reaction

How It Technically Works

New Class of High Efficiency Materials

In this reversible chemical reaction, the thermal energy transforms into chemical energy. In the forward reaction, thermal energy serves as the power source to drive the chemical reaction and it is able to store heat by breaking the chemical bonds in the AB molecules, dissociating AB into A and B. It is an Endothermic Process. In the reverse reaction, since the intrinsic property of exothermic reaction, the A and B molecules bind together and produce AB compounds, transforming the chemical energy back to thermal energy and releasing a large amount of heat. During the process of thermal energy storage and release, the most important thing is that the heat is stored in chemical form without any thermal waste and the energy in the chemicals do not fade in a long time with exergetic efficiency up to 96% or better.

Significantly Improves Energy Conversion Efficiency

Metal Hydride is a reversible exothermic chemical reaction, the thermal energy transforms into chemical energy. Energy can be stored in the Metal Hydride indefinitely. The storage will not decrease efficiency over time, other types of batteries have a limited life span.

Pressure and Temperature

The Metal Hydride Battery consists of a hot and a cold side. Similar to Heat Pumps and Refrigerators and Air Conditioners, putting heat in contact with cooler, lower pressure environments so that the heat can naturally transfer. The Hydride Battery is charged by the heat from an electric furnace fed by the electricity generated from solar cell panels. This heat creates a reaction between the metals and hydrogen to store the heat energy. Hydrogen contains the maximum energy per mass among all fuels.

The main advantage of hydrides, namely their compactness, can be used to the full extent with a Hydride Battery, ultimately more cost-effective. Low cost and a high efficiency performance. Hydride Batteries are also safer, the current lithium-ion batteries are susceptible to catastrophic fire and explosion incidents.

Rather than storing an electrical charge, Hydride Batteries converts the electrical input to heat

Applications: To firm up renewables projects. As a peaking resource for Utilities, Industry, Government. Metal Hydride Batteries will also be used for peaking power and for power grid support and as auxiliary batteries.

A New Class of High Efficiency Materials

Our Hydride Battery will be using composite hydrides-alloys for reversible high temperature energy storage which are a class of materials containing metal or metalloid bonded to hydrogen.

This new class of proprietary, high efficiency, Metal Hydride, has no degradation problems. It is able to store the heat for an extremely long time. With close to zero energy losses and no corrosion and it does not include any rare metals. It is a balanced system that yields consistent steady-state cycling behavior.

This thermal energy storage technology intensifies the storage of heat by more than ten times compared to latent and sensible heat storage technologies.

Investing in Energy Storage for a Carbonless Future

Metal Hydride Batteries stores electricity from any power source in the form of heat and creates electricity from that heat. Heat turned into electricity.
