At a ribbon-cutting ceremony at SCG’s cement plant in Saraburi Province, Thailand, Rondo Energy and SCG Cleanergy, a subsidiary of SCG specializing in clean energy solutions, announced the start of operation of Southeast Asia’s first heat battery.
The heat battery is now delivering 2.3MWth of continuous steam, charged from the grid and a nearby floating solar farm. Superheated steam delivered by the unit drives a steam turbine, generating 24-hour clean electricity used in cement production.
“Today we’re announcing three big steps in Rondo’s journey,” said Rondo CEO Eric Trusiewicz. “We’re launching our first unit that is part of our new modular sizing approach, our first heat battery in South-East Asia, and the only one worldwide delivering high-pressure steam used for electric power generation.”
New Modular Platform: Flexible Unit Sizing from MWs to GWs
The unit unveiled today is a 33 MWh Rondo Heat Battery, the first built on Rondo’s new modular platform. Rondo now offers the Rondo Heat Battery with sizes ranging from 33 MWh to >1GWh, all with a common design, common construction, and common supply chain.
Mass-manufactured brick and wire heating elements are combined and configured to a range of RHB sizes, to meet the specific needs of each customer’s application — from smaller units suited for food and beverage producers, to larger units delivering more than 100 MWth for the needs of the world’s largest chemical plants and metals refineries.
Rondo’s modular platform combines the benefits of a mass manufactured common core design that delivers certainty for customers and investors, with the ability to configure heat output, steam conditions, storage size, charging rate, and other aspects of the heat battery to deliver maximized project value.
