Vesta Field Pilot

Vesta Field Pilot

North Sea Beach, Southampton, NY, USA

Coastline enhanced rock weathering

In July 2022,  the North Sea Beach Colony (NSBC) in Southampton, NY became home to the world’s first field pilot of Coastal Carbon Capture when they incorporated olivine sand into Phase 2 of their beach restoration project. The Town of Southampton, in collaboration with the NSBC, Vesta, and First Coastal, deployed 500 cu yd of olivine sand such that it comprised ~5% of the total sand volume that was placed.

Lithos

Lithos

San Francisco, CA, USA

Carbon capture for thriving farms.

Lithos accelerates mineral weathering by spreading basalt on croplands to increase dissolved inorganic carbon with eventual storage as ocean carbonates. Its technology uses novel soil models and machine learning to maximize CO₂ removal while boosting crop growth.

greenSand

Enkhuizen, Noord-Holland, Netherlands

Removes CO2 using Olvine

greenSand focuses on removing certified CO2 using the mineral Olivine. Removal by reactions with olivine is an attractive option, because it is widely available and reacts easily with the (acid) CO2 from the atmosphere. When olivine is crushed, it weathers within a couple of years, depending on the grain size and humidity. The reaction is exothermic but slow. The end-products of the reaction are silicon dioxide, magnesium carbonate, and small amounts of iron oxide.

Artic Fox

Artic Fox

Hellisheidi Power Plant, Hellisheiðarvirkjun, Selfoss, Iceland

Captures CO2 and turns it into stone

Carbfix captures CO2 and turns it into stone underground in less than two years through proprietary technology. The company’s mission is to be a key instrument to tackle the climate crisis and substantially reduce global CO2 emissions. Since 2017, Carbfix has worked in collaboration with Climeworks, a Swiss clean-tech company specializing in direct air capture (DAC) technology. Climeworks developed a small DAC pilot plant (Arctic Fox) next to the Carbfix CO2 mineral storage operations at the Hellisheidi geothermal power plant as a part of the EU funded Carbfix2 project. The power plant supplies renewable energy to the DAC process, whilst Carbfix provides a permanent and safe storage solution for the captured atmospheric CO2.

Carba Prototype Reactor

Carba Prototype Reactor

WM - Burnsville Sanitary Landfill, Cliff Rd W, Burnsville, MN, USA

Permanently bury nature-based biomass for thousands of years.

Carba specializes in low energy Carbon Dioxide Removal (CDR) solutions with permanent storage. Through low temperature pyrolysis (torrefaction) we convert nature-based biomass/waste into graphitic carbon and permanently bury/store it for thousands of years.

Bio-Restorative Ideas (BRi) X Puro

Bio-Restorative Ideas (BRi) X Puro

San Juan, Puerto Rico

Transform any organic matter into fixed carbon

BRI developed a model for achieving rapid carbon footprint reduction through permanent sequestration of CO2 while providing environmentally and socially conscious revenue sources. They transform any organic matter into fixed carbon that gets stored permanently in the soil and in the process quantify how much carbon was sequestered from the atmosphere.

Carbon Drawdown Initiative

Carbon Drawdown Initiative

Fürth, Germany

Extensive greenhouse experiment to investigate MRV approaches for rock weathering.

In their extensive greenhouse experiment, the carbon drawdown initiative is trying to find ways to measure the CDR effects caused by adding rock dust to agricultural soils on short timescales (months to years). Overall, they record 4.5 million data points per day. Their mission is to find a short term (month/years) measuerment approach for ERW.

ecoLocked

ecoLocked

Spandauer Straße / Grunerstraße, 10178 Berlin, Germany

Turn biochar into functionalized building materials.

ecoLocked is turning buildings into carbon sinks. We convert captured carbon from waste biomass (biochar) into powerful, carbon-negative construction materials. Our products permanently store CO2 in the built environment, reduce the need for fossil raw materials, and deliver material performance improvements in areas like insulation, durability and production efficiency. We just released our first product, an additive to create 100% carbon-neutral concrete (ready-mixed & precast). The video below shows an example project with ready-mixed concrete.
