For production process application, results indicate that for high concentrations (25% LiCl), the use of high current densities could reduce undesired transport of salts (for in- stance, in the case of the bipolar membrane Fumasep FBM, a current density of 1000 A∙m−2). Thus, electric current through bipolar membranes is transported mostly by H+ and OH− ions generated by water dissociation in the bipolar membrane, and to a lower extent by leakage of Li+ and Cl− salts. 16 of 29 Limiting current densities for the Neosepta BP membrane were lower, indicating that it possesses characteristics more suitable for operating at high electrolyte concentrations leakage through the bipolar membrane and, therefore, a base with fewer impurities might (see Table 2). Studies have been reported that indicate a decrease in salt leakage through be obtained. bipolar membranes by increasing the thickness of one of the cationic or anionic layers that In none of the obtained curves (see Figure 7) the second limiting current density— compose a bipolar membrane [44]. A similar effect can be expected when comparing the associated with the limited diffusion of water molecules towards the catalytic interface of Neosepta BP and Fumasep FBM membranes, with the former being thicker. the bipolar membrane—was observed.

Product and Development Focus for Infinity Turbine

ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.

Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system.

Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications.

We call it the Cogeneration Battery or Cogen Battery.

One project is converting salt (brine) based water conditioners to simultaneously produce power.

In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).

Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).

We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.
