Greenhouse Gas

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. 

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.

Given all the recent attention, you’d think the prospects for carbon-capture project development are fantastic. In the U.S., last year’s Inflation Reduction Act (IRA) featured significant increases in the 45Q tax credit for carbon sequestration, improving the economics for a wide range of carbon-capture projects. On a global level, it seems clear that efforts to reduce greenhouse gas (GHG) emissions and reach a net-zero world will continue for a long time to come. Nearly every plan to reach that target includes a significant reliance on carbon capture, with the International Energy Agency (IEA) forecasting that 7,600 million metric tons per annum (MMtpa) of carbon dioxide (CO2) — that’s 7.6 gigatons per year — will need to be captured and sequestered by 2050. We are a long way from those levels, given that most estimates put global carbon-capture capacity at a little more than 40 MMtpa today, or less than 1% of what the EIA thinks we’ll need in less than 27 years. In today’s RBN blog, we look at the main factors holding back the wider commercialization of carbon-capture initiatives in the U.S.

Cargo ships move more than 80% of the world’s internationally traded goods, making them essential to the global economy, but they’ve traditionally been fueled by heavy fuel oil or marine gasoil, both of which are emissions-intensive. With 60,000 or so ships in service, they account for an estimated 2.8% of global greenhouse gas (GHG) emissions, a percentage the International Maritime Organization (IMO) would like to reduce. At the 80th session of the IMO’s Maritime Environment Protection Committee (MEPC) in July, the group adopted a provisional agreement to eliminate GHG emissions from shipping by a date as close to 2050 as possible, with intermediate goals for emissions reduction by 2030 and 2040. Clearly, radical innovations will be required to meet the IMO’s goals. In today’s RBN blog, we look at some of the initiatives directed at emissions reduction in shipping and the challenges to (and opportunities for) operational improvements, especially regarding LNG carriers.

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.

By now, just about everyone is aware of and has been impacted by efforts to reduce greenhouse gas (GHG) emissions — and methane especially — as a way of meeting global climate goals, but that doesn’t mean everyone is on the same page. The energy industry is a leading source of methane emissions in the U.S., but with nearly 1 million active wells across the country and not much common ground on the actual scope of methane emissions and how best to reduce them, finding a path forward without overburdening the sector and its customers is more than a little tricky. In today’s RBN blog, we preview our latest Drill Down Report on efforts to reduce methane emissions.

The oil and gas industry is being pushed by regulators, third parties and investors to better identify and mitigate its methane emissions, especially the few “super-emitter” sites that make outsize contributions to overall emissions. But while operators are ramping up capital spending on new technology, one thing has become clear: There is no silver bullet when it comes to reducing emissions, and each option includes one or more drawbacks, including source attribution, costs, quantification, and detection limits. In today’s RBN blog, we’ll break down the advantages and disadvantages of the different measurement technologies.

The buzz and activity around renewable diesel (RD), a chemically identical “drop-in” replacement for traditional petroleum-based diesel, continues to grow. The goals with RD, which is produced from renewable feedstocks, are to reduce the need for petroleum and to lower life-cycle greenhouse gas (GHG) emissions — critical steps in meeting climate agendas in many countries. Canada recently enacted legislation designed to promote the domestic production of RD as part of a broader emissions-reduction strategy. In today’s RBN blog, we take a tour of the newly emerging RD production sector in Canada and examine whether it could one day replace imports from the U.S.

Over the past couple years of energy market turbulence, pretty much everyone has come to acknowledge that the U.S. — and the rest of the world — will continue to require refineries and refined products for decades to come. It’s also likely, though, that U.S. refiners, like their European counterparts, will be required to do more to reduce the volumes of carbon dioxide (CO2) and other greenhouse gases (GHGs) generated during the process of breaking down crude oil and other feedstocks into gasoline, diesel, jet fuel and other valuable products. And, thanks to new federal incentives, it might even make sense for refineries to capture and sequester at least some of the CO2 they can’t help but produce. In today’s RBN blog, we begin a series on refinery CO2 emission fundamentals, the differing policies that are applied here in the U.S. and abroad, and how those policies might ultimately influence refining competitiveness.

Oil and gas companies across the value chain are facing new pressures to manage and reduce methane emissions. Their ability to access premium markets and buyers, appeal to investors and avoid costly fees depends on developing a credible plan to measure and reduce methane emissions. At the very least, the industry’s regulatory outlook, its non-governmental quasi-oversight and its access to capital are changing in ways that make understanding sometimes inconsistent emissions data vitally important. In today’s RBN blog, we explore the recent changes and the mounting external pressures around methane emissions.
