The Inflation Reduction Act: A quantum leap in US clean energy, yet hurdles remain for comprehensive green shift

As the nation charts its course towards a greener future, certain sectors, particularly hydrogen, geothermal, and nuclear energy, find themselves mired in regulatory and practical quandaries.


Since the landmark Inflation Reduction Act (IRA) took effect in 2022, the United States has witnessed a notable acceleration in its clean energy ambitions, effectively doubling the rate of carbon emission reductions. Emboldened by this legislative momentum, over 80 projects spanning solar, wind, and energy storage sectors have flourished, buoyed by the Act’s generous mix of direct payments and tax incentives. However, as the nation charts its course towards a greener future, certain sectors, particularly hydrogen, geothermal, and nuclear energy, find themselves mired in regulatory and practical quandaries.

Unpacking the IRA’s financial commitment

The IRA, coupled with the Bipartisan Infrastructure Law, earmarked a staggering $239 billion for an array of initiatives aimed at decarbonizing the economy. This allocation signifies a substantial uplift of 38% from the prior year, spotlighting the government’s heightened commitment to combat climate change. Analysts, including those from the prestigious Goldman Sachs Group, project that the IRA’s financial outlay could escalate to an eye-watering $1.2 trillion by 2031, dwarfing the initial $400 billion forecast.

Identifying the early beneficiaries

The electrical power sector, alongside battery manufacturing and established clean energy sources like wind and solar, have emerged as the primary beneficiaries of the IRA’s largesse. This influx of incentives has not only catalyzed domestic growth but has also attracted significant foreign investment, compelling Europe to conceive its own Green Industrial Plan amidst fears of losing clean-energy projects and talent to the US.

Despite these advances, the expansion of critical infrastructure such as transmission lines and electric vehicle (EV) charging stations has been stymied by a thicket of state and local regulations. Moreover, the Act’s sluggishness in galvanizing other green initiatives, notably hydrogen and carbon sequestration projects, has drawn scrutiny.

Voices from the field

Jigar Shah, head of the Department of Energy’s loan programs office, emphasized the Act’s broad impact: “The IRA has been a catalyst for clean energy projects across the board, from solar to wind to battery storage.”

However, the transition has not been seamless. Darren Woods, CEO of Exxon Mobil Corp, expressed concerns over regulatory hurdles, particularly for hydrogen projects: “The challenge has been translating the legislation of the IRA into regulation.”

Jason Bordoff, founding director of the Center on Global Energy Policy at Columbia University, highlighted practical barriers: “Even with the IRA, companies are facing a host of practical barriers to putting the tax breaks to work.”

Navigating the geopolitical and domestic landscape

The IRA’s ripple effects extend beyond the confines of clean energy production, stirring both international consternation and domestic policy debates. The Act’s stringent stipulations on EVs have raised alarm bells among US automakers about the potential influx of more affordable Chinese vehicles, prompting calls for heightened tariffs and stricter adherence to US content regulations.

The specter of Asian dominance in advanced technology crucial for EVs and other green energy apparatus has spurred the US to make aggressive forays into semiconductor manufacturing, a move aimed at safeguarding its technological sovereignty and competitive edge in the clean energy domain.

Despite the IRA’s instrumental role in propelling the US towards a more sustainable energy paradigm, the journey is fraught with obstacles. Regulatory hurdles continue to impede the advancement of complex projects favored by oil companies, such as hydrogen plants and carbon capture systems. These challenges underscore the need for greater clarity and efficiency in translating the IRA’s ambitious legislative framework into actionable, on-the-ground realities.

As the US endeavors to align its climate action with the pressing imperatives of the Paris Agreement, the IRA’s comprehensive impact on the nation’s clean energy trajectory remains a subject of intense scrutiny and debate. The Act has undeniably catalyzed significant progress, yet the consensus among experts suggests that an escalation in efforts is imperative to achieve the overarching goal of net-zero emissions by 2050.

“The IRA doubles the pace of reductions but should have tripled it to hit our 2030 climate goals,” said Jesse Jenkins, a professor at Princeton’s Mechanical and Aerospace Engineering department.
