Big day for giant scissors enthusiasts at Holcim! They finally found the perfect ribbon to test their collection.
Utilities want to burn clean hydrogen in gas plants to achieve a carbon-free grid. But a lot of climate hawks say hydrogen as a power-plant fuel is greenwashing par excellence. bit.ly/3vXbJbj
Big pivot for Solidia
Big thanks to Ingram Ready Mix & 5M for joining us in a groundbreaking moment for Solidia — a successful first concrete pour in Texas with Solidia SCM™! Together, we redefine what's possible in concrete technology! Here's to more groundbreaking moments & sustainable solutions.
I feel like CCUS should be more of a thing you hide away shamefully in a closet when guests come over as opposed to Plan A for cement decarbonization.

One weird trick to decarbonize by 2030! (at least on your sustainability report) crh.com/media/press-re…

What does it cost to capture half the emissions from one cement plant? ~$1B USD for CO2 capture retrofit at the cement plant (Brevik: 400,000 tons CO2/yr targeted) ~$1B USD for the sequestration infrastructure (1/3rd of the $3B total). OPEX is extra! ccsnorway.com/status-june-20…
Hype among green cement/concrete startups appears inversely correlated to techno-economic merit in most cases. Many are fighting logistical and thermodynamics battles they won't win. Examples to follow!
Karen has lost patience with some of the more severe eco-cement hype! youtu.be/VYhIv9YhDWw?si… Without pointing fingers...
