Heimdal pulls CO2 and cement-making products out of seawater using renewable energy
One of the effects of rising CO2 levels in our atmosphere is that levels also increase proportionately in the ocean, hurting wildlife and changing environments. Heimdal is a startup working to pull that CO2 back out at scale utilizing renewable resource and producing carbon-negative industrial materials, including limestone for making concrete, while doing so, and […] The Heimdal procedure, which has actually been demonstrated at laboratory scale (believe terrariums instead of thousand-gallon tanks ), is roughly as follows. Terraformation is a big advocate of solar desalination, and Heimdal fits right into that formula; the two are working on a main partnership that should be announced quickly. Wong points out that the primary cost of Heimdal’s business, beyond the preliminary ones of buying tanks, pumps, and so on, is that of solar energy. All in all it appears to make for an appealing investment, and though Heimdal has not yet made its public debut (that would be forthcoming at Y Combinator’s Summer season 2021 Demonstration Day) it has actually drawn in a $6.4 million seed round. …
