What are the top three problems in climate mitigation or adaptation that still lack scalable tech solutions in 2025?

Three critical climate challenges remain unsolved due to technical complexity, economic constraints, and infrastructure requirements that current technologies cannot address at the scale and cost needed for global deployment.

Scalable methane emission mitigation represents the largest near-term opportunity, as methane accounts for 28% of global warming potential but lacks affordable detection and capture solutions for agriculture, landfills, and upstream oil and gas operations. Current technologies cost $200-500 per ton of methane captured, far above economic viability thresholds of $50-100 per ton required for widespread adoption.

Climate-resilient infrastructure faces a $300 billion annual investment gap for flood defenses, heat-adapted building materials, and emergency response systems. Existing solutions require massive capital expenditure and years-long construction timelines, while climate impacts demand rapid deployment of modular, cost-effective protective infrastructure that can be installed within months.

Affordable sustainable aviation fuels represent a $50 billion market opportunity with no commercially viable production pathway. Current synthetic fuel production costs $5-8 per gallon compared to $2-3 for conventional jet fuel, requiring breakthrough innovations in catalysis, renewable energy integration, and supply chain logistics to achieve cost parity while meeting aviation industry volume requirements.

What are the key technology, supply chain, or infrastructure bottlenecks limiting the scale-up of climate solutions?

Three critical bottlenecks constrain climate tech scaling despite strong demand and policy support: critical mineral supply chains, infrastructure gaps, and financing barriers for mid-stage projects.

Critical mineral supply chains face geopolitical risks and production constraints that limit battery and electrolyzer manufacturing capacity. Lithium, nickel, and rare earth elements concentrate in politically unstable regions while processing remains dominated by single countries, creating supply vulnerability for climate tech manufacturers. Current mining capacity can only support 60% of projected 2030 battery demand.

Infrastructure gaps prevent deployment of proven technologies, particularly CO₂ transport and storage pipelines required for carbon capture projects. The U.S. needs 65,000 miles of CO₂ pipelines by 2030 but has only 5,000 miles currently, while grid interconnection capacity cannot accommodate planned renewable energy projects with average 4-year connection delays.

The "missing middle" financing gap affects projects requiring $45-100 million in capital that are too large for venture capital but too small for infrastructure funds. These projects struggle to secure blended capital combining grants, debt, and equity while facing higher risk premiums due to limited operational track records in climate tech sectors.

Regulatory uncertainty creates investment hesitation despite supportive policies, as changing administrations and policy frameworks make long-term capital commitments risky. Permitting processes for renewable energy and carbon removal projects average 3-5 years, delaying deployment and increasing capital costs through extended development periods.
