Financing the Transition to a Net-Zero Future

The report identifies a significant investment gap for breakthrough decarbonization technologies, noting that approximately $50 trillion in incremental investments is required by 2050 for a global net-zero transition. It argues that current financial flows are insufficient and skewed toward investment-grade assets, leaving a 'valley of death' for early-stage commercial deployment. To overcome this, the report proposes technology-specific financing blueprints that blend public and private capital, transformative business models using long-term offtake agreements to reduce 'green premiums', and targeted public interventions. Specific analysis is provided for sustainable aviation fuel (SAF), carbon capture and storage (CCS) in steel, hydrogen-based direct reduced iron (H2-DRI) in steel, and ammonia-powered shipping.

• A massive investment gap exists for the global transition to net-zero, with an estimated $50 trillion in incremental investments needed by 2050. While current clean energy investments are significant, breakthrough technologies for industrial decarbonization—such as carbon capture, hydrogen, and bioenergy—received only about $16 billion in 2020, requiring a multifold increase in the next decade.
• Breakthrough technologies often face a 'valley of death', where businesses cannot secure financing for initial commercial-scale deployment. This is driven by a mismatch between the risk appetite of financiers and the high capital intensity and risk of early-stage projects, as well as a lack of 'bankable' opportunities.
• Current climate-aligned bond flows are inadequate for the transition because they are heavily skewed toward investment-grade assets (90% rated BBB or better) and the transport sector, specifically large railway companies, rather than high-need sub-sectors like aviation and shipping.
• To improve bankability, the report proposes 'capital blending blueprints' that combine diverse sources of capital. Multilateral development banks (MDBs) are identified as the ideal anchor investors to coordinate these ecosystems and syndicate flows from the private sector.
• Transformative business models are required to reduce 'green premiums' (the cost difference between zero-carbon and brown technologies). This includes using long-term offtake agreements, tolling structures, and availability-based payments to create predictable revenue streams.
• For aviation, Sustainable Aviation Fuel (SAF) via gasification/Fischer-Tropsch (GAS-FT) is a key pathway. Financing requires a blend of capital, as banks are unlikely to take full construction risks, and demand must be stimulated through blending mandates and voluntary green premiums from passengers and corporates.
• In the steel sector, Carbon Capture and Storage (CCS) can be retrofitted to existing processes, but requires a developed carbon transport and storage network. Financing for non-recourse CCS projects often requires 80% or more of debt to be covered by Export Credit Agency (ECA) guarantees to be viable.
• Hydrogen-based direct reduced iron (H2-DRI) for steel involves high scale-up risk. The report suggests a 'deconsolidated' project structure, financing the hydrogen plant and the electric arc furnace separately to manage technological and business model risks independently.
• Shipping's transition to green ammonia is hindered by the high cost of fuel and the fragmented international nature of the industry. Because vessels have long lifespans (25-35 years), existing high-emission ships risk becoming stranded assets. Global regulatory frameworks via the International Maritime Organization (IMO) are essential to avoid 'first-mover disadvantage'.
• Public policy must move beyond piecemeal interventions to provide long-term predictability. Recommended actions include establishing global blending mandates, providing carbon pricing/rebates, and ensuring that 'green' definitions do not inadvertently lead to divestment from emerging markets and developing countries (EMDCs).
