|---|---|---|---|
| XFuel is a fuel company that provides green and clean fuels to distributors and consumers. The company was founded in 2010 and is based in Palma de Mallorca, Baleares. | $20M / Series A / Jan 27, 2026 | ||
| Reneo is the leading end-to-end asset transformation- and decarbonization platform for residential real estate in Germany. Using proprietary software technology to identify and realize the ecological and economic potential of stranded assets. | $46.9M / Feb 20, 2025 | ||
| OCELL is a Munich-based climate-tech startup that develops local climate projects that are transparent, measurable, and effective. Our mission is to unlock the full potential of forests and make a significant contribution to climate mitigation. To achieve this, we use aerial photographs, data from various sources, and artificial intelligence tocreate ‘digital twins’ of forests. These provide valuable insights into forest growth, current carbon storage capacity, and other metrics, and enable us to predict optimal forest management strategies. With our state-of-the-art technology and unwavering commitment to data transparency, we ensure the effectiveness of our solutions. Currently, OCELL manages over 250,000 hectares of sustainable forest land in Europe, North America, and South America. | $10.4M / Series A / Jan 29, 2025 | ||
| We integrate used electric car batteries into a battery storage system and thus build up a decentralized storage network. | $8.8M / Series A / Oct 04, 2024 | ||
| Concrete is the most widely used building material on our planet. The only thing mankind uses more of is water. With a wave of urban development coming in the next few decades, concrete is also a rapidly growing trillion-dollar market. However, cement and concrete production is responsible for 8% of the global CO2 emissions, making its growth a bigcause for concern.Low-carbon concrete exists - but until now it has been too sophisticated to be produced reliably and on a large scale. It contains very little burnt limestone - responsible for the strength of concrete and CO2 emissions. This makes low-carbon concrete vulnerable to fluctuations in raw materials and operating conditions and thus difficult to produce with reliable quality. Adding to the challenge: the final quality of concrete can only be measured weeks AFTER it has been processed on the construction site - far too late to be corrected. This is why our world is still built on more robust, high-carbon concrete. Using alcemy's software, cement and concrete producers receive precise quality predictions already during production. Based on these prediction models, our AI identifies which production parameters need to be adjusted to mitigate the impact of fluctuations. Thus, the quality of cement and concrete can be optimized BEFORE delivery – for the first time in history.The result is significantly more consistent product quality, allowing producers to safely replace burnt limestone with less expensive, low-carbon materials found in nature. In this way, they can also avoid payments for CO2 emission certificates in the EU. Saving costs, bringing production processes up to speed for 21st century concrete recipes, and saving half of Europe’s CO2 emissions goes hand in hand at alcemy. Join us on our journey to make low-carbon concrete a reality! | $10M / Venture - Series Unknown / Jul 05, 2024 | ||
| Share your charge point with friends, family, or neighbors on the street. We make sharing a no-brainer! Monta GreenCharge forecasts the availability of renewable energy and manages your charging to reduce CO2 emission. Monta - Driving Innovation | $86.9M / Series B / Jan 23, 2024 | ||
| UNDO is a world-leading carbon dioxide removal project developer specialising in enhanced rock weathering. Enhanced rock weathering is a nature-enabled technology that permanently locks away carbon dioxide from the atmosphere. The geological process of weathering has happened naturally for millions of years, removing billions of tonnes of carbondioxide over Earth's history. UNDO accelerates this natural process by spreading crushed rock with a high reactive surface area onto agricultural land, where plants and microbes in the soil speed up the weathering process. The breakdown of the rock by carbon dioxide dissolved in rainwater releases nutrients and bicarbonates, which end up in the oceans as solid carbonate minerals, permanently removing carbon dioxide from the atmosphere. Part of Stripe’s 2021 Climate Portfolio, UNDO is scaling operations in the UK and US. The rock, a by-product of the aggregate and mining industry, is given to local farmers for free and applied on agricultural land using existing infrastructure. In addition to permanent, rapid and scalable carbon removals, UNDO’s holistic partnership model delivers significant co-benefits such as improved soil health, ocean deacidification and increased profits for farming communities. | $12M / Venture - Series Unknown / May 21, 2023 | ||
