Decarbonizing Operations Cement Manufacturing Firm Cemex Invests in Green Hydrogen Start Up Hiiroc

With this investment, Cemex plans to increase its hydrogen injection capacity across its cement operations while reducing the consumption of fossil fuels leading to the decarbonization of its processes. Hiiroc has introduced a technology that makes use of thermal plasma electrolysis to convert biomethane, flare gas, or natural gas into clean hydrogen at a lower cost than other existing solutions.

San Pedro Garza García/Mexico – Cemex and Cemex Ventures (Cemex's corporate venture capital unit) have announced their investment in Hiiroc, a clean hydrogen production startup. Hiiroc developed a technology that uses thermal plasma electrolysis to convert biomethane, flare gas, or natural gas into hydrogen at a lower cost than competing solutions and without a CO2 footprint. Together with Hiiroc, Cemex aims to increase its hydrogen injection capacity across its cement operations while reducing the consumption of fossil fuels.

Hiiroc, a UK-based company founded in 2019, has developed a novel process that efficiently produces high purity hydrogen and clean carbon black at superior temperatures and pressure. As part of this investment, Cemex and Hiiroc aim to increase Cemex's hydrogen injection capacity in its cement kilns, allowing for a higher alternative fuel substitution rate of fossil fuels. This initiative is designed to further cut methane emissions and other greenhouse gases downstream, a key objective set at COP26 in Glasgow.

"Hiiroc's solution is sustainable, scalable, cost-effective, and has strong growth potential inside the hydrogen ecosystem. This investment is yet another important step in our transition from fossil to alternative fuels and towards achieving our Net Zero goal for 2050. This partnership allows us to further expand our hydrogen knowledge in the ultimate quest to replace fossil fuels with hydrogen in our plants," said Gonzalo Galindo, Head of Cemex Ventures.

This investment is part of Cemex's roadmap to achieve its ambitious climate action goals under its Future in Action program, investing today in one of the most relevant sectors for decarbonizing cement operations. With the leverage and synergetic combination of multiple promising technologies, Cemex aims to achieve its goal of delivering net-zero CO2 concrete by 2050.
