Hydrogen Deployment Milestone For Cemex And HiiROC

The title of this post, is the same as that of this article on Agg-Net.

This is the sub-heading.

Cemex kick-start first-of-a-kind low-carbon hydrogen project using thermal plasma electrolysis in cement production

These first two paragraphs add more detail.

CEMEX Ventures, Cemex’s corporate venture capital (CVC) and open innovation unit, announced today an initial hydrogen deployment at industrial scale with HiiROC, the pioneering British hydrogen company that produces affordable, clean hydrogen, at their Rugby cement plant in the UK.

Hydrogen has emerged as a low-carbon energy source within the construction industry’s decarbonization roadmap and offers potential as an energy solution to help reduce the sector’s reliance on fossil fuels and lower CO2 emissions. This venture marks a significant milestone for Cemex, as it represents the beginning of a large-scale strategic project plan with the aim to further lower their carbon emissions in cement production.

These third paragraph is a good outline of HiiROC and how it can be deployed.

HiiROC produce carbon-neutral hydrogen using their proprietary Thermal Plasma Electrolysis (TPE) process, which requires just one-fifth of the electrical energy used in water electrolysis and captures carbon as a solid by-product, avoiding CO2 emissions – a game-changer for the industry. HiiROC’s modular solution can be deployed as single units to full-scale industrial plants, and the hydrogen produced can be used as an alternative energy source to fuel clinker production processes, helping Cemex to achieve their decarbonization goals.

Centrica, Cemex, Hyundai, Kia and others are investors in HiiROC.

I asked Google AI, what percentage of carbon emissions came from cement production and got this answer.

Cement production accounts for roughly 8% of global carbon dioxide (CO2) emissions, according to think tank Chatham House. This makes it a significant contributor to climate change, with the industry’s emissions comparable to the total emissions of some countries.

If HiiROC can take a big bite out of carbon emissions, by reducing cement production’s 8 % share, they would be on a winner.
