Scalable, modular, high temperature, cost-efficient thermal energy and power storage and conversion system made of upcycled industrial by-products

Introduction

300 TWh of energy, that's 51 billion, from heat sources is wasted every year in the EU due to the lack of cost-efficient, space-saving, and scalable storage systems. Heat losses equal net heat demand, a dramatic waste of resources and capital.

Problem Statement

Industrial companies and energy producers waste excess energy because intermediate storage or conversion to electricity is not economic.

Solution Overview

With KRAFTBLOCK, economic energy storage and conversion becomes affordable for the first time. Our patented storage granule is produced from 85% upcycled blast furnace slag and a self-developed binding agent.

Advantages of KRAFTBLOCK

• Storage capacity per meter is increased by a factor of 10.
• Storage price per MWh is reduced by a factor of 12.

System Features

The granule is part of our energy storage system, which consists of stackable units of 60 MWh. This system enables:

1. Heat-to-heat operations
2. Heat-to-power operations
3. Power-to-heat operations
4. Power-to-power operations

Target Industries
