ClimeRock

ClimeRock gives natural silicate fertiliser to farmers free and monetises the carbon-removal impact by selling carbon removal certificates to corporate buyers, so its sales motion is direct enterprise climate procurement rather than farm-gate sales. Convincing buyers to pay for high-quality removal is the founders' stated main commercial hurdle.

The go-to-market is dual-sided: farmers receive the silicate fertiliser at no charge and are treated as the company's best allies and channel to agricultural soils, while revenue comes from selling measured CO2 capture as certificates to organisations committing to net-zero. The founders name persuading buyers to pay more for high-quality removal certificates, with no purchase obligation, as their biggest challenge; as of October 2024 the company had not yet sold carbon offsets, citing the need for concrete backing of drawdown claims.

Growth turns on scaling from pilots to hundreds of hectares, building local ERW hubs that pair farm demand with nearby rock, and hiring science and operations staff. The founders name future fundraising, early adopters and R&D as the enablers.

Its stated path runs from pilots toward deployment across hundreds of hectares, extending to fields elsewhere in France and regions with favourable conditions, moving basalt by train or barge where quarries are distant, and building local ERW hubs that match agricultural needs with suitable nearby rock. The founders name securing funding, gaining early adopters and continuing R&D as prerequisites, alongside team growth starting with science and operations hires; independent reporting frames 2026 as a French CDR scale-up year contingent on stronger national policy support.

ClimeRock's risks centre on unproven measurement and verification of carbon removal, the cost of soil and water sampling, and buyer willingness to fund credits that return no immediate value. Broader sector risks include contamination from reactive rocks and doubts over permanence in temperate soils.

The core risk is measurement: ClimeRock lacks the mechanisms to concretely back its drawdown claims, its sampling work is costly, and it depends on scientific partners to validate removal and agronomic effects. Commercially, buyers face no purchase obligation, and the founders name persuading them to pay for higher-priced, high-quality certificates as the biggest challenge. Sector risks include contamination from fast-weathering rocks such as olivine, doubts over permanence of inorganic carbon in temperate conditions, and the lifecycle costs of moving rock at scale.

ClimeRock's offering suits buyers who want durable carbon removal with an agronomic return: enhanced rock weathering that turns quarry by-product basalt into both a free soil amendment and a measured, certificate-sold carbon-removal product for farmland.

What makes that package defensible is its local, dual-value design. Finely ground silicate rock from nearby aggregate quarries is applied free to soils, where weathering stores CO2 durably as dissolved bicarbonate while cutting acidity and releasing crop nutrients. ClimeRock screens locally available rocks on composition, weathering potential and agronomic suitability, quantifies removal and agronomic effects through field trials while improving MRV, and explores local ERW hubs matching rock sources with farm demand.
