Instead, steam, gas turbine can be powered by heat and diesel engines can be powered thermal energy, heat, stored as molten metal, combined with liquid nitrogen or highly compressed air.

Spokesman Shiva Vencat says the Perryman battery system is timely, considering the IMO has just agreed to cut emissions by at least 50 percent by 2050. He also cites Wood Mackenzie's prediction that global shipping fuel costs are likely to rise by a quarter in 2020 when the global sulfur cap takes effect.

Like furnaces and kilns, energy in the battery is contained within layers of refractory material. The core consists of trays and inertial dampeners. “These space-age and traditional refractory materials remains stable for millions of melts,” says Vencat. A solid-state thermal transfer material extracts the energy. The battery is charged using magnetic induction from any electrical source with energy conversion efficiency, electrical to thermal that exceeds 98 percent.

“Only nuclear power can store more energy than a Perryman battery,” says Vencat. “Yet our technology is safer than an art-class kiln.” With it, we can possibly increase the thermal efficiency of an engine by as much as 30 percent, and can retrofit any internal combustion engine old or new, he says.
