CleanTechnica 45秒前InPlanet German-Brazilian启动开创性的使用增强了岩石风化一并删除作为大规模碳的方法。成立于2022年8月,它最近完成了一项成功的种子计划资金,获得一系列国际投资者的支持。InPlanet也加入Carbonfuture催化剂项目和参与ClimAccelerator: CDR。我们采访了InPlanet创始人Felix Harteneck领导German-Brazilian公司的挑战,严格MRV系统构建可伸缩的重要性二氧化碳去除(CDR)技术,以及他的关注一并受到CDR过程已经在自然界中发现。你能先给我们一个简短的解释什么InPlanet吗?InPlanet是一个增强的岩石风化一并公司。我们总部在德国,以及电力、巴西。我们正在构建一个平台连接农民和矿山,以传播吨岩石固碳粉在未来几年。你能给一个简单的解释增强岩石风化吗?岩石风化本身是地球上最重要的自然过程移除大气中的碳,发生在世界各地,所有的时间。 When it rains, a small amount of CO2 in the atmosphere reacts with the rainwater to form a weak carbonic acid, which then reacts with rocks and starts to dissolve them. As the rocks dissolve, the minerals in the rock react with carbon to form bicarbonates. These bicarbonates then effectively lock the carbon away for thousands of years. Every year the earth sequesters around one gigaton of carbon through this natural process. What we do with Enhanced Rock Weathering is basically to optimize and speed up this process. Naturally, it takes hundreds of years to sequester carbon this way, whereas we can bring it down to five years or less. We can also optimize the location of the weathering, to get the most potential out of the rock: we use five tons of rock powder to sequester one ton of CO2. And the rock we use is very accessible, it’s a basalt silicate rock, which makes up 80% of the earth’s rock. So we take it and spread it across farmland in the tropics, where it can start to sequester carbon. What other benefits does ERW have? The main co-benefit is that the rock also fertilizes the soil. Farmers in Brazil have been very open to collaborating with us, because we’ve found that the rock powder can replace up to 50% of chemical fertilizers. By replacing fertilizers with rock powder, they get huge cost benefits, as we provide them with the rock powder for free. We’ve also seen in our pilot projects that the farmers’ yields increase, meaning they have an increased income as well as reduced costs, so it’s a very attractive deal for them.

Electrifying Industrial Heat for Steel, Cement, & More I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours.Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
