Frontier has opened applications for its 2026 Innovation programme, expanding its early-stage funding beyond prepurchases to explicitly support research and development in carbon removal. The programme targets novel approaches and 'last-mile challenges' in ocean alkalinity enhancement, surficial mineralisation, and open-system measurement, reporting, and verification (MRV). This initiative aims to address remaining innovation gaps in promising pathways, building on progress made since 2022 in over 60% of identified research challenges. Frontier will offer more flexible check sizes to support these R&D efforts. The organisation noted that some early carbon removal models were over-optimistic, citing issues with cold weather impacts on direct air capture (DAC) and challenges with certain biological approaches like kelp sinking and engineered biopolymers.
