Renewables

Passage of the Inflation Reduction Act (IRA) in August 2022 was intended to unleash a wave of clean-energy initiatives, from hydrogen and renewable fuels to electric vehicles and large-scale carbon-capture projects, all part of the Biden administration’s plans to reduce carbon dioxide (CO₂) emissions and move the U.S. closer to a net-zero economy. But while billions in federal financing and tax credits have helped move many projects forward, they can only advance as fast as permitting, regulations and economic reality will allow. In today’s RBN blog, we look at the surge in proposed carbon-capture projects since passage of the IRA, where they are in the review process, and how the pace of permitting at the federal level compares with the states that have primacy over their own sequestration wells. 

The intermittent nature of renewable energy is a well-documented thorn in the side of efforts to decarbonize the power grid, especially with more wind and solar generation coming online every year. But while those sources of clean energy are not available all the time, it’s also true that they can sometimes produce more power than transmission lines or a power grid can handle during other periods, leading to curtailments. An increasingly important tool that can lessen the impact of both problems is power storage. In today’s RBN blog, we’ll address the limitations of today’s storage options and look at how long-duration energy storage (LDES) could play a critical role in the years ahead.

When the Inflation Reduction Act (IRA) was passed into law in August 2022, it earned near-unanimous acclaim from longtime supporters of renewable energy and decarbonization efforts. Industry types also approved of the bill’s focus on incentives to fuel new developments. One of its most ambitious elements was creation of the 45V production tax credit (PTC) for clean hydrogen, a central part of the Biden administration’s efforts to build a clean-energy economy. But while the PTC may have a significant impact on the U.S. energy landscape over the long run, the December 2023 rollout of the proposed rulemaking has generated no small amount of criticism. In today’s RBN blog, we’ll lay out some of the changes that some say should be included in the final rulemaking to help the clean-hydrogen economy make a quick break from the starting gate instead of getting left at the back of the pack. 

The Biden administration has placed some big bets on clean hydrogen, seeing it as a replacement fuel for some hard-to-abate industries and putting it at the heart of its long-term decarbonization efforts. All of these bets are backed by a brand-new tax credit. But the goal isn’t just to drive production of more hydrogen — it’s also to make hydrogen in a specific way, with measurable decreases in greenhouse gas (GHG) emissions. That means producing hydrogen that qualifies for the tax credit is going to be a lot easier said than done. The proposed rules include a concept called deliverability — one of the “three pillars” of clean hydrogen — that adds further challenges to producers hoping to cash in on the tax credit and puts into further peril any number of potential projects. In today’s RBN blog, we’ll explain how deliverability works, how it fits into the proposed rules, and the challenges it will pose for hydrogen producers and power generators alike. 

Discussions and debates around the carbon-capture industry have been everywhere in recent years, from the federal incentives designed to spur its growth and the role it might play in decarbonization efforts to the technical challenges and economic headwinds that add uncertainty to its long-term outlook. And while all of those are important topics worthy of future conversation, none of those potential projects are going to happen without somewhere to put all that carbon dioxide (CO₂). The wells used for permanent CO₂ sequestration are largely approved at the federal level by the Environmental Protection Agency (EPA) but a few states have gained control — aka “primacy” — over the permitting process. In today’s RBN blog, we explain what it means to have primacy, why it has become an increasingly important goal in recent years, and the potential benefits that come with it. 

It’s been a tough couple of months for developers of large-scale, multi-state carbon capture and sequestration (CCS) projects, which have been stung by widespread public opposition and often hamstrung by state and local regulations. But while those factors helped lead one developer to pull the plug on its project and another to push back its schedule by a couple of years, that’s not to say there isn’t a path forward for some projects. In today’s RBN blog, we examine why Wolf Carbon Solutions’ targeted approach and a pipeline conversion by Tallgrass Energy could be the most likely CCS projects to reach operational status. 

If it seems like the push for decarbonization has suddenly picked up the pace lately, Michigan provides proof. Home to the Big 3 automakers and for many the symbolic heart of U.S. manufacturing, its efforts to move away from fossil fuels have long been met with skepticism and resistance. But changing attitudes about climate change and renewable power — and full Democratic control of the state government for the first time in 40 years — have led to a swift about-face in the state’s energy policy. In today’s RBN blog, we examine Michigan’s plans to accelerate its transition away from coal-fired power and the long-term challenges that come with it.
