It will be equipped with a 12.2MW waste heat recovery plant, 6MW-worth of which will be commissioned in October 2022, with the remainder to follow in 2023. A dedicated fossil fuel-fired power plant and 35km-long railway siding will follow some time in the 2024 financial year.

US: Thailand-based Siam Cement Group (SCG) has invested in Rondo Energy, developer of the Heat Battery. The cement company aims to help its various business lines to decarbonise their operations through deployment of Rondo Energy’s technology. Rondo Energy said that the partnership will support and earlier expansion of its product’s footprint across Southeast Asia and worldwide.

Rondo Energy chief executive officer John O’Donnell said “Rondo is excited to be working with SCG. Rondo’s technology opens a new pathway for SCG to achieve their deep decarbonisation goals and simultaneously reduce their operating costs. SCG’s deep capabilities in execution and quality will enable Rondo to deliver reliable energy infrastructure rapidly and at scale. Together, Rondo and SCG have the global footprint to deliver deep decarbonisation projects, including heat as a service projects in Southeast Asia and worldwide.”

UK: Breedon Group, together with Australia-based First Graphene, Morgan Sindall Construction & Infrastructure and the University of Manchester, is developing a new reduced-CO₂ graphene-enhanced cement. The consortium is currently formulating the cement using varying doses of First Graphene’s PureGRAPH graphene-enhanced grinding aid. The project received a research grant from the UK government earlier in 2022. First Graphene says that the study involves one of the largest commercial trials of its kind to date globally. It is simultaneously collaborating on another similar trial with a Europe-based speciality chemicals producer.

On 29 September 2022, First Graphene launched its latest range of graphene-enhanced cement grinding aids and concrete additives. These join recent launches PureGRAPH AM, an admixture developed in collaboration with South Africa-based Nanoproof/Glade Chemicals, and HexMortar, a dry mortar mix which will be distributed by New Zealand-based GtM Action.

First Graphene says that its cement and concrete segment’s order pipeline totals US$113m in value. Managing director and chief executive officer Michael Bell said “It is pleasing to see our efforts, and those of our collaboration partners, coming to fruition at a commercial scale. One of the primary drivers for the adoption of graphene solutions in this segment is the reduction of CO₂ emissions. We’re seeing considerable benefits both in the immediate reductions that can be achieved through the use of graphene-enhanced grinding aids, as well as the potential reductions in concrete usage because of the enhanced physical properties these products provide.” Bell concluded “Working with industry-focused partners such as Nanoproof/Glade Chemicals, GtM Action, Breedon Cement and Fosroc opens the way to an estimated addressable market of more than 12,000t of PureGRAPH across the medium to long term.”
