marcuslima··on Launch HN: Heimdal (YC S21) – Carbon neutral cement
Existing players have all been overwhelmingly positive! From their perspective we're not competing with their core business and they don't have to change any of their existing plants to use our product. All they have to do is buy from us rather than a mining company to get carbon neutral cement. The main push-back is the need to perform testing on the product to make sure they udnerstand performanc before integrating in production at scale. The biggest problem on our side is sorting out planning approval to build facilities on the coast that use seawater

Thanks! Actually the process is carbon negative as not all is stored as carbonates that can be used in cement production. But for the materials we sell it's 1:1. One molecule of CO2 is captured for every molecule that's emitted in production

We're building it out to ~300 tonnes/year in the next few months. Our commercial partners don't need more than 20-30kg of product for initial testing and then just a few tonnes to run industrial testing.

Thanks! You're right the current version is pretty small. The demo we're building is just about making enough product for our commercial partners to test in their facilities. That way they can confidently sign binding purchase agreements that we'll leverage to build commercial scale facilities. We're aiming to build our first commercial scale plant next year. Since our product is chemically identical to mined limestone, only much more pure we're confident we have a compatible product!
