When Energy Met Density

New Energy Storage Solutions

In the popular imagination, energy density is gaining some new recognition because people are starting to understand that a tank of gasoline or diesel can be smaller and lighter than an electrical battery, and give a car a greater range. In fact, diesel is 27x more energy dense than Li-Ion batteries, so what should we think of a battery that is three times more dense than diesel fuel? Impossible, don’t you think? Well, no. Not since Perryman Technologies have been improving their thermal storage design, which is capable of being loaded from any source of electricity with magnetic induction and can be deployed anywhere to generate electricity from the heat and achieve remarkable system efficiencies.

These self-contained units can be made the size of a 10′, 20’or 40′ container, for respectively 55/122, or 305 MW/h equivalent of thermal storage, or in various custom dimensions. This compares favorably to the huge arrays of lithium-ion batteries that are common today.

The energy is supplied via a highly efficient magnetic induction system and could come from any renewable source, be it wind, solar PV or Hydro, or from the grid. These physical properties give new meaning to the word dispatchable energy. It is literally possible to provide a Mississippi river barge with 36GW of electricity wherever it is needed.

The same concept could be implemented on an even smaller scale and the heat from a thermal battery could be combined with the tremendous expansion of Liquid Nitrogen (LN2), something that has been demonstrated in the past, but wasn’t very practical until a portable, non-combustion heat source could be deployed, which is now the case. We have that now with a thermal storage that is cool to the touch, and has no combustion, and zero fire risk.

Again, the reason this is interesting is exactly because using Lithium Ion batteries in long haul transport adds tremendous weight, resulting in a reduced payload.

Perryman Technologies patented a Non-Combustion Brayton Cycle Engine technology six years ago. With this technology, an existing gas or diesel engine can be converted into a potentially completely “green” engine (depending on the power source). in 2019 SolChill/Perryman Technologies were a finalist in the IEEE’s Empowering a Billion Lives competition, with their containerized storage solution. Currently, they are a semi-finalist for the 2023 contest with their conversion concept for existing gas and diesel engines, with the use of solar, wind or hydro power.

We strongly support Perryman and its mission and for Chrismas 2022 and the new year 2023, our greatest wish is you would support them too. What they need is donations for their team to the IEEE crowdfunding campaign. They have some large donors, but the mission now is to show wide geographic participation, and donations of $25 or $50 are very helpful. For more information, I am hereby posting a pdf:
