Green Boiler

An Omni-Purpose Thermal Storage & Steam Supply System

The Holtec Green Boiler is a long-duration thermal storage device. It can store vast quantities of heat at an elevated temperature for long periods with minimal parasitic losses to the environment. The Holtec Green Boiler also has a built-in steam generator to produce steam or heated water at the pressure and temperature desired by the user. Long-duration thermal energy storage systems give its user the ability to store thermal energy when it is abundant and to use it when needed.

Key Features

The Green Boiler components are sized to be shop manufactured and shipped by land or sea.
The standard design target used to size the Green Boiler vessels is 12 hours at full power. This on-power duration can be increased, if necessary, for a particular application
Energy can be stored for long periods with little parasitic loss to the ambient.
The storage system is modular; the energy storage capacity is theoretically limitless because there is no limit on the number of modules that can be arrayed at a site.
All or a portion of the steam from the Green Boiler can be diverted to serve as process steam for other industrial applications such as making the hydrogen fuel.
The Green Boiler does not use any rare materials; all materials can be sourced domestically in any industrial country.
Unlike batteries, the Green Boiler does not have a finite cycle life. No part of the Green Boiler suffers from a discernible rate of service life expenditure.
Unlike Li-ion batteries, the Green Boiler is not vulnerable to fire.
Green Boiler’s capital cost is competitive with a battery installation; It has an incomparably longer service life (ie, period of depreciation).
Roughly speaking, about 2 sq. ft. of land is needed to store each MWH of thermal energy (land use is proportional to the quantity of energy stored).
The Green Boiler installation should be sheltered from rain, wind or snow for optimum performance.
