U.S. DOE Bolsters Energy Infrastructure Investment Under Inflation Reduction Act (IRA)

U.S. Department of Energy USA

Overview

The Inflation Reduction Act (IRA) provides an additional $40 billion in loan authority for projects eligible under Section 1703 of the U.S. Department of Energy’s (DOE) Energy Policy Act, available until September 30, 2026. Furthermore, the IRA established the new Energy Infrastructure Reinvestment (EIR) program (Section 1706). This program offers loan guarantees for projects that retool, repower, reuse, or replace energy infrastructure that has ceased operations, or for projects that enable operating energy infrastructure to avoid, reduce, utilize, or sequester air pollutants or anthropogenic greenhouse gas emissions, significantly bolstering clean energy investments.

In Depth

Background: The Inflation Reduction Act (IRA) and Accelerating Clean Energy Investment

Enacted in 2022, the U.S. Inflation Reduction Act (IRA) is a landmark piece of legislation aimed at addressing climate change, accelerating clean energy investments, and lowering healthcare costs. This law significantly promotes investments in clean energy sectors, including renewables, electric vehicles, batteries, and hydrogen technologies, through extensive tax credits, direct payments, and loan guarantees. Modernization and decarbonization of energy infrastructure, in particular, stand as one of IRA’s primary pillars.

Enhanced Energy Infrastructure Investment: Section 1703 and the EIR Program

The Inflation Reduction Act substantially strengthens the U.S. Department of Energy’s (DOE) loan guarantee programs and introduces new mechanisms to accelerate the energy infrastructure transition.

• Strengthening Section 1703 Loan Guarantees: The IRA allocated an additional $40 billion in loan authority to the existing loan guarantee program under Section 1703 of the Energy Policy Act of 2005. This funding is available until September 30, 2026, and is designated to support innovative clean energy projects and the commercialization of advanced technologies that contribute to CO2 emission reductions. This additional financing can serve as a critical funding source for large-scale green hydrogen projects, among others.
• Creation of the Energy Infrastructure Reinvestment (EIR) Program (Section 1706): The IRA established the EIR program as a new loan guarantee initiative to support the energy transition. This program targets the following types of projects:
  • Reuse of Ceased Operations Infrastructure: Projects that retool, repower, reuse, or replace energy infrastructure that was previously operational but is now shut down (e.g., coal-fired power plants, former nuclear sites) into clean energy production facilities (e.g., renewable energy, hydrogen production facilities). This aims to revitalize regional economies while leveraging existing infrastructure.
  • Emission Reduction for Operational Infrastructure: Projects that introduce technologies enabling currently operating energy infrastructure to avoid, reduce, utilize, or sequester air pollutants or anthropogenic greenhouse gas emissions. This includes carbon capture and storage (CCS), energy efficiency improvements, and conversion to hydrogen combustion.

Impact and Outlook: U.S. Energy Transition and Economic Opportunities

These loan guarantee programs under the Inflation Reduction Act have the potential to dramatically alter the scale and speed of clean energy investment in the U.S. For hydrogen projects, in particular, due to their capital-intensive nature, DOE loan guarantees provide a powerful incentive to mitigate project financing risks and facilitate Final Investment Decisions (FIDs). This is expected to stimulate domestic manufacturing, strengthen supply chains, and create new jobs, thereby contributing to long-term economic growth and energy security. The IRA will continue to be closely watched as legislation fundamentally reshaping the landscape of the U.S. energy transition.
