Kraftblock Volt | Eneco & PepsiCo

Commissioning engineering for the world's largest commercial high-temperature thermal energy storage system. A heat battery that replaces a 25 MW gas boiler at the PepsiCo plant in Broek op Langedijk.

Commissioning Energy Transition Heat Storage Electrical Engineering
Kraftblock Volt heat battery installation at PepsiCo Broek op Langedijk

Project Description

Through our network, we were approached to provide support for the commissioning of a groundbreaking energy project: the Kraftblock Volt project at the PepsiCo plant in Broek op Langedijk. This is the world's largest commercially deployed high-temperature thermal storage system.

The system, owned by energy supplier Eneco, replaces a 25 MW gas-fired boiler with green heat from the Kraftblock heat battery. This heat is used to heat thermal oil that drives the frying processes of the chip factory. This eliminates 98% of the factory's CO2 emissions, saving thousands of tons of CO2 per year.

Our Role

KTS provides a commissioning engineer / electrical engineer who works on site for at least 6 months to complete and start up the new installation. The engineer is responsible for guiding the commissioning phase, testing and validating electrical systems, and ensuring safe and successful startup.

About the Volt Project

The project is being realized in two phases. In the first phase, 70 MWh of storage capacity is installed distributed over two power block units. In the second phase, three more units are added, for a total capacity of more than 150 MWh. The system charges with green electricity and delivers heat up to 800°C, without modifications to the existing factory infrastructure.

This concept is replicable for the entire food industry and other sectors such as chemicals, paper and heavy industry. Kraftblock's Net-Zero Heat System makes it possible to replace fossil fuels without major modifications to the production process.
