Hydrogen has a well-established, if limited, role in the modern economy. It has been used in refining and ammonia production for decades, but its potential has long been touted in various areas, including decarbonizing hard-to-abate industrial processes such as steelmaking, as well as in larger roles in heavy-duty transportation and energy storage. The last few years have seen a significant push to expand hydrogen’s role — an attempt to capitalize on its versatility and lack of carbon dioxide (CO₂) emissions —  but a number of formidable obstacles to wider adoption remain, including price, availability and infrastructure, in addition to its tenuous political support. In today’s RBN blog, we look at the challenges that make forecasting the industry’s growth difficult and the emerging consensus around the most practical end uses for hydrogen. 

Over the past few years, tax credits and other incentives — both financial and regulatory — have breathed life into the U.S. market for sustainable aviation fuel, whose production is now ramping up, with more SAF capacity on the way. But the sector may experience turbulence under the incoming Trump administration, which has pledged to undo much of the Inflation Reduction Act (IRA) and pull back on the stepped-up decarbonization efforts that helped define the Biden presidency. In today’s RBN blog, we discuss the latest developments in the SAF space and the choppiness the still-fledgling sector may soon face. 

One of the biggest challenges to a significant expansion of the commercial hydrogen market in the U.S. is the lack of a comprehensive transportation network. That has spurred interest from utilities, government agencies and others interested in utilizing or repurposing parts of the existing (and extensive) natural gas infrastructure to ship hydrogen. But that approach comes with some challenges, starting with the significant differences in the physical and chemical properties of hydrogen and methane, the main component of natural gas. In today’s RBN blog, we’ll explain why moving hydrogen on the existing natural gas network — then storing and utilizing it — is no easy feat. 

Given the frothy targets to reduce U.S. carbon emissions set by the 2016 Paris Agreement and an anticipated expanding role in that process for low-carbon-intensity (LCI) hydrogen that is barely being produced in 2024, it’s hard to believe there’s a path forward. Yet one recent study from industry participants in the National Petroleum Council (NPC), commissioned by the Department of Energy (DOE), provides detailed projections of how and where LCI hydrogen will develop, including regional variations. In today’s RBN blog we review that analysis. 

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.
