Tech giants such as Google, Amazon and Meta have long sought to meet their data-center power needs while at least limiting their greenhouse gas (GHG) emissions. But while many developers and utilities have turned to natural gas to power data centers because of its ability to provide reliable 24/7 power, renewable generation continues to play a role, especially if it includes plans to utilize on-site battery storage. Data centers are increasingly being co-located near new renewable generation sources, which can also boost grid reliability, as we explain in today’s RBN blog. 

Soaring demand for around-the-clock electricity, tied to the development of large-scale data centers, has sparked a renewed interest in carbon-free nuclear power. Given that conventional nuclear plants can be very challenging to site and permit, there’s been a lot of talk about installing small modular reactors (SMRs) at the sites of coal-fired power plants that have been taken offline for environmental and economic reasons but still have critical connections to the power grid and other infrastructure. In today’s RBN blog, we examine the potential to replace coal with nuclear and preview our latest Drill Down Report on the growing enthusiasm for nuclear power in the U.S. 

In Texas, rising power demand, increasing dependence on variable-output renewables, and declining availability of dispatchable fossil-fired plants to back up wind and solar have left the Electric Reliability Council of Texas (ERCOT) power grid in a pickle. As part of its response, the Public Utility Commission of Texas (PUCT) adopted a tool called the Performance Credit Mechanism (PCM) to help ensure the grid will be able to meet a yet-to-be-defined reliability standard. But while key metrics for the PCM have been identified, the details will determine which dispatchable resources will be supported with additional revenue, how much the whole approach will cost, and how effective it might be. In today’s RBN blog, we explore the debate ahead of the PUCT’s August 29 meeting — where it is expected to finalize rules around the PCM — and explore the difficulty of compensating generators annually so that they are also there for those once-in-10-year events. 

Many have argued that U.S.-sourced LNG can be instrumental in combating climate change by helping countries around the world replace coal-fired generation with natural gas-fired power. While this argument carries a lot of force in the eyes of many politicians and LNG marketers, the questions of exactly how — and to what extent — LNG can replace coal need to be asked. In today’s RBN blog, we’ll look at the challenges that the expanded use of LNG faces in countries with high coal utilization and the possible means of overcoming them. 

We’ve spent a lot of time this year looking at the global move to decarbonize and explaining why there isn’t going to be a straight line leading directly to abundant carbon-free power and a net-zero world. That might be the way a lot of people would like to see it go, but that’s not the reality we’re now facing. All sorts of obstacles have popped up, indicating that the energy industry’s trilemma of availability, reliability and affordability not only clash with each other on occasion, they can also conflict with economic and environmental priorities. Nowhere is that more evident than in the U.S., where small-scale battles over the clean-energy transition are playing out all over the map. In today’s RBN blog, we discuss highlights from our newly released Drill Down Report on the ways the nation’s clean-energy push is playing out at the state level. 

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. 

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.

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 has become abundantly clear over the past couple of years that energy transition isn’t going to be a straight line leading directly to abundant carbon-free power and a net-zero world. All sorts of obstacles have popped up, indicating that the energy industry’s trilemma of availability, reliability and affordability not only clash with each other, they can also conflict with environmental priorities. The challenge is being felt now in Hawaii, where a commitment to expanding energy production from renewable sources and tamping down the use of fossil fuels while also keeping prices under control and reducing pollution is turning out to be no easy feat. In today’s RBN blog, we look at Hawaii’s recent efforts to phase out coal- and oil-fired power generation, why that’s turned out to be easier said than done, and what it all means for environmental performance and energy prices.
