carbon intensity

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. 

It seems logical that shifting over time to aviation fuel with a lower carbon footprint would represent the most practical way for the global airline industry to reduce its greenhouse gas (GHG) emissions. But for that shift to happen, there needs to be an economic rationale for producing sustainable aviation fuel and, despite a seemingly generous production credit for SAF in the Inflation Reduction Act (IRA), that rationale is a least a little shaky when compared to renewable diesel (RD) credits available today. In today’s RBN blog, we conclude our two-part series on SAF with an examination of RD and SAF economics (which are remarkably similar), the degree to which existing SAF incentives may fall short of RD, and what it all means for SAF producers and production.

Around the world, there’s a strong push to put aviation on a more sustainable footing and reduce the industry’s greenhouse gas (GHG) footprint. Increasing the production of sustainable aviation fuel (SAF) — a close cousin of renewable diesel (RD) — is key to this effort. But while the economic case for producing RD in the U.S. has been compelling for some time thanks to government subsidies, the returns on investment for producing SAF appear more dubious, despite a seemingly generous production tax credit for SAF in the Inflation Reduction Act (IRA). As we discuss in today’s RBN blog, the incentive for making jet fuel is likely too small — and too short-lived — to overcome the higher cost of production for SAF compared to RD, and additional incentives may be needed to spur meaningful increases in SAF production.

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.

There’s a growing acknowledgment in the U.S., Europe and elsewhere that crude oil will remain an important part of our energy future for decades to come. At the same time, however, the drive to decarbonize will continue, and as part of that effort, oil producers will be working to ratchet down their greenhouse gas (GHG) emissions. A lot of that will be achieved through the purchase of carbon offsets or the use of carbon capture and sequestration (CCS), but another approach is for producers to “high-grade” their portfolios by divesting production assets that generate inordinately high volumes of carbon dioxide (CO2) and methane during production and investing instead in assets with much lower carbon intensity. In today’s RBN blog, we discuss the push by some producers to shift to “lower-carbon oil.”

California faces a broad set of challenges when it comes to reducing wildfires, which have been increasingly frequent and intense over the last decade — impacting the lives of those dealing with the threat, not to mention effects on the economy and environment. Separately, the state has been working to reduce transportation-related pollution and incentivize the development and use of a wide array of alternative fuels. Yosemite Clean Energy (YCE), which announced plans for its first plant site in late 2021, has an approach it says will not only make the state a cleaner and safer place but also foster the development of new transportation fuels. In today’s RBN blog, we look at YCE’s plans to turn wood waste into renewable fuels, how its unique “Stump to Pump” approach relies on partnerships with local communities, and the green hydrogen and renewable natural gas it plans to produce at sites across California.

Ethanol is a biofuel that is found in nearly 98% of the gasoline purchased at retail stations in the U.S., in most cases accounting for 10% of the gasoline/ethanol blend. This high-octane, biofuel has grown in popularity around the world, particularly over the last 20 years, due to regulations that require or incentivize its use. As governments continue to evaluate regulations to control greenhouse gas (GHG) emissions, ethanol has been overshadowed by some other biofuels lately but it is expected to continue to play an important role as a pathway for meeting low-carbon mandates. Today, we discuss the history, the production, and the still-evolving role of ethanol in the global push to decarbonize.

As governments and corporations around the world evaluate methods of decarbonization across sectors, one focus area has been transportation, since the petroleum fuels used to mobilize economies are significant contributors to greenhouse gas (GHG) emissions. California’s Low Carbon Fuel Standard (LCFS) is one of the longest-running programs for carbon intensity (CI) reduction targeting the transportation sector and provides an ideal case study to review for a better understanding of how one type of GHG reduction policy is anticipated to work. As many of the principles in this pioneering program are being evaluated for replication elsewhere, its results and consequences are still in the making. In today’s blog we’ll provide an overview of the Golden State’s groundbreaking LCFS, looking at its history, how it functions, and its effectiveness at meeting its goals to date.

As part of the Paris Agreement and other regional sustainability goals, countries across the globe are formulating strategies to reduce greenhouse gas emissions. The resultant policies target numerous different areas such as stationary emissions, electricity production, and transportation fuel sourcing. Within the transportation sector, one aspect that has spurred quite a bit of investment relates to reducing the carbon intensity of transportation fuels. The “low carbon fuel” policies that are in place today, coupled with those that are being evaluated for the future, have the potential to displace a sizeable portion of the petroleum-based fuels in the regions where they are adopted. In today’s blog, we begin a series on low carbon fuel policies, the mechanisms being evaluated to meet increasingly stringent regulations, and the impact these regulations could have on refined-products markets.
