How do we create continuous, stable power delivery of renewable energy from variable sources, while maintaining a low CO² footprint for private and public consumption?

ADI Solar Corp. has designed a revolutionary high-temperature thermal storage solution which provides dispatchable energy using the remarkable chemical energy storage capacity of calcium hydride. ADI Solars ingenious  system provides a solution for reversibly storing energy from any high temperature thermal source such as solar or nuclear. The heat energy is stored chemically when it is used to separate calcium hydride into its constituent components; calcium and hydrogen.  This energy can then be reclaimed as heat by allowing the calcium and hydrogen to recombine to form calcium hydride in an exothermic (heat producing) chemical reaction.   In this way, heat energy can be stored and recovered at need for use in generating electricity.   The storage system can be used to provide variable power output from constant power sources (such as nuclear) or to provide steady power output from variable power sources (such as solar).   

The result is a revolutionary breakthrough to store heat for true 24/7 baseload energy production and/or to add load following capability to existing baseload capability.  It is an enabling technology to make renewable energy a competitive alternative.

    Storing Heat Energy

    Within the ADI chemical thermal storage system, calcium and hydrogen provide a thermally reversible high temperature energy storage solution using the “heat of formation” of calcium hydride(the heat required to break its chemical bond). Solar generated heat is "used" to separate calcium hydride into its constituent elements, calcium and hydrogen. This heat energy can be recovered by allowing the hydrogen to recombine with the calcium in an exothermic reaction. In this fashion, the heat is not really used, but stored for later use....

    The ability to store thermal energy is a significant breakthrough in the renewable energy market. There is no comparable known chemical thermal storage solution that exists on the market today, and ADI Solar Corps transformative breakthrough technology will have a tremendous impact (long term) to the nation’s ability to store energy from solar, nuclear and other high-temperature heat producing elements. ADI Solar Corp.’s Chemical thermal storage solution is critical to the future success of alternative energy because...

  • Background

    In 1999, with the help of co-founders Gerald Fargo and George Weinmann, Wayne Bliesner founded high tech startup Alternative Designs, Inc. (ADI) to pursue development and commercialization of his several inventions. In 2000 he left Boeing for ADI to focus on developing an ultra-high-temperature Dual Shell Stirling engine. The engine was developed to provide the highest heat-to-electric conversion efficiency, while reducing manufacturing costs to make it a market-changing solution. In 2000, at the urging of its investor base, ADI split off its Stirling Engine technology into a separate company, ADI Thermal Power Corp.,focused solely on the Stirling Engine. Over the next 8 years ADI Thermal evolved the engine/genset into its present day functioning prototype, but required further funding for full power durability testing. Surviving these ambitious development years involved overcoming technical and financial obstacles that would have failed less persistent companies. Yet the engine’s greater potential, to make mainstream solar power generation a reality....
