The push to decarbonize frequently focuses on the transportation sector, which is responsible for the largest share of global greenhouse gas (GHG) emissions. That has led to increased blending of ethanol into gasoline and the development of several alternative fuels, most notably renewable diesel (RD) and sustainable aviation fuel (SAF). But as production of those two fuels accelerates, an often-overlooked byproduct of their creation is beginning to attract more attention: renewable naphtha. In today’s RBN blog, we explain the similarities and differences between traditional naphtha and renewable naphtha, look at how renewable naphtha is produced, and show how it can be used to help refiners, petrochemical companies and hydrogen producers meet their sustainability goals and reduce the carbon intensity (CI) of their products.

Every state has its unique set of advantages and challenges, but very few face the number of contrasts that makes New York and its ambitious decarbonization goals so interesting. The Empire State ranks fourth in population (behind California, Texas and Florida) and is home to the biggest city in the country, yet most of the state would be considered rural. It has the nation's third-largest economy, but because its key industries — including financial and business services — are not energy-intensive, and many in the New York City area use mass transit, its per-capita energy use is lower than all but two states (Hawaii and Rhode Island). And while the state gets about 30% of its power from renewable sources (most of it large-scale hydropower), solar and wind generation are still very limited there. In today’s RBN blog, we look at how the state’s plans to ramp up renewable generation — which have long been plagued by problems with incentives, permitting and project cancellations — are running headlong into the difficulties of adding so many resources in a short period of time.  

Plans to greatly expand the production of low-carbon energy and reduce greenhouse gas (GHG) emissions can be found just about everywhere, from national and international policy discussions to debates at the state and local levels. Given the potential for dramatic economic, social, and geopolitical impacts over the coming decades, it’s no surprise that top-down mandates for a transition to a more renewables-centric energy mix and away from fossil fuels can stir up concern over the pace, scale, and ultimate effectiveness of such a massive undertaking. In some places, like California, critical voices are largely drowned out. In other spots, apprehension may fester just below the surface. But in a state like Texas that identifies so closely with the energy industry, the conversation is right out in the open. In today’s RBN blog, we look at how that debate is playing out in Texas, where renewable energy is booming in a state known for fossil fuels. 

Second chances don’t always come around, but when they do, you’d do well to learn from your previous experiences and make the most of them. For the Petra Nova carbon-capture/enhanced-oil-recovery (EOR) project southwest of Houston, its previous three-year run largely confirmed the preconceived notions of critics as a highly touted project that fell short of expectations for a variety of economic and technical reasons. But it also enjoyed some significant successes, and now the facility has been given a second life, courtesy of a new owner and higher oil prices. In today’s RBN blog, we look at the long-awaited restart of the Petra Nova project, what its owner hopes to gain from it, and what it could mean for the carbon-capture industry.

The uncertainties around solar power are well understood. When the sun doesn’t shine as much as expected, power grids that rely heavily on solar must turn elsewhere to meet consumer demand. And while a shortfall in solar generation can be tricky to navigate, the difference between actual and forecast levels is typically only a few percentage points, and power grids are usually ready and able to make up any difference. But what happens when the daytime sun is obscured for hours at a time? Much of the U.S. is about to find out. In today’s RBN blog, we’ll preview the path of the October 14 solar eclipse, detail its expected impact on the generation of electricity, and describe what steps are being taken to keep power grids performing as usual.

Clean ammonia, which is produced by reacting clean hydrogen with nitrogen and capturing and sequestering the resulting carbon dioxide (CO₂), is gaining momentum. In just the past few months, several more new clean ammonia production projects have been proposed along the U.S. Gulf Coast, many of them made possible by commitments from Japanese and South Korean companies that see the low-carbon fuel as an important part of the Far East’s future energy mix. Taken as a group, the dozen-plus projects now under development have the potential to produce tens of millions of tons of clean ammonia annually, and to create yet another massive energy-export market for U.S. producers. In today’s RBN blog, we discuss the new projects moving forward — and one being put on hold — and what’s driving the clean ammonia market.

It’s no secret that the past several months have been challenging for the wind power industry, especially when it comes to offshore projects. Major developers have sought to renegotiate power-purchase agreements (PPAs) signed years ago, delayed work on some projects, and walked away from others, despite severe financial repercussions in some cases. On top of all that, only one of three offshore tracts available in the U.S.’s first Gulf of Mexico lease auction for wind power attracted any bids. It all amounts to a major setback in the Biden administration’s goal for the nation’s electricity to be 100% carbon-free by 2035. In today’s RBN blog, we look at the significant challenges being faced by wind power developers, what they mean for the projects currently under development, and some changes that could eventually help bring more of the renewable power online.
