With an announcement in late 2023 by Dow Chemical that it would be undertaking an enormous expansion of its ethylene production site in Fort Saskatchewan, AB, it was immediately clear that Alberta’s ethane supplies would need to increase by a significant 110 Mb/d. As we’ll discuss in today’s RBN blog, a deal was signed in February between Dow and Pembina Pipeline Corp. that calls for the midstreamer to provide up to 50 Mb/d of additional ethane supplies and, according to executives at Pembina’s investor day earlier this month, will require the company to invest between C$300 million (US$220 million) and C$500 million (US$367 million) to build out its existing NGL/ethane infrastructure.

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.

Predictions about what the energy market and the global economy might look like in the future can feel a bit like stargazing — the closer something is, the clearer it appears. But if something is really far away, even the Hubble Space Telescope won’t bring it precisely into view, especially if it’s a still-developing solar system or a distant planet. That’s pretty much where things stand with bioethylene, which could become a shooting star but might also end up as a big cloud of dust. In today’s RBN blog, we discuss the developing market for bioethylene: where it’s being made, what changes might make it more economical to produce in the U.S., and its target markets.

Carbon dioxide is not the most potent of the greenhouse gases, but it is by far the most prevalent, which makes it a primary focus of efforts to protect the planet. And while a lot of attention is being paid to ways to reduce CO2 emissions and to capture those that are produced, it’s important to remember one key fact: There’s strong demand for CO2 for a variety of commercial uses, from enhanced oil recovery and fertilizers to industrial processes and beverage production. In other words, CO2 has real value to certain parts of the global economy and capturing CO2 for sale to these customers must be factored into the decarbonization equation. In today’s RBN blog, we take a closer look at the industrial CO2 value chain.

Discussions about energy transition and increased electrification are all around us, whether they involve accelerating the ramp-up in renewable power sources such as wind and solar, facilitating the shift to electric vehicles, or switching to alternative fuels like hydrogen. But amid all the talk about the evolution to a low-carbon world — and away from oil and gas — there’s one area that is sometimes overlooked: petrochemicals. In the U.S., most steam crackers use natural gas liquids (NGLs) as their primary feedstocks, and they also consume a lot of energy — two big red flags in an increasingly ESG-focused world. And that’s giving bioethylene, billed as a green alternative to traditional ethylene, a moment in the spotlight. In today’s RBN blog, we look at how bioethylene is produced, how it differs from ethylene produced from traditional measures, and why it may someday evolve into an attractive alternative for the petrochemical industry, even though it’s far from a sure thing.
