bp’s Archaea Energy is the largest renewable natural gas (RNG) producer in the U.S., with an industry leading RNG platform and expertise in developing, constructing and operating RNG facilities to capture waste emissions and convert them into low carbon fuel.

Archaea partners with landfill owners, farmers and other facilities to help them transform their feedstock sources into RNG and convert these facilities into renewable energy centers.

Starlee Sykes, Archaea Energy’s CEO, shared more about bp’s acquisition of the company and their vision for the future.

HETI: bp completed its acquisition of Archaea in December 2022. What is the significance of this acquisition for bp, and how does it bolster Archaea’s mission to create sustainability and stability for future generations?  

Starlee Sykes: The acquisition was an important move to accelerate and grow our plans for bp’s bioenergy transition growth engine, one of five strategic transition growth engines. Archaea will not only play a pivotal role in bp’s transition and ambition to reach net zero by 2050 or sooner but is a key part of bp’s plan to increase biogas supply volumes.

HETI: Tell us more about how renewable natural gas is used and why it’s an important component of the energy transition?  

SS: Renewable natural gas (RNG) is a type of biogas generated by decomposing organic material at landfill sites, anaerobic digesters and other waste facilities – and demand for it is growing. Our facilities convert waste emissions into renewable natural gas. RNG is a lower carbon fuel, which according to the EPA can help reduce emissions, improve local air quality, and provide fuel for homes, businesses and transportation. Our process creates a productive use for methane which would otherwise be burned or vented to the atmosphere. And in doing so, we displace traditional fossil fuels from the energy system.

HETI: Archaea recently brought online a first-of-its-kind RNG plant in Medora, Indiana. Can you tell us more about the launch and why it’s such a significant milestone for the company?  

SS: Archaea’s Medora plant came online in October 2023 – it was the first Archaea RNG plant to come online since bp’s acquisition. At Medora, we deployed the Archaea Modular Design (AMD) which streamlines and accelerates the time it takes to build our plants. Traditionally, RNG plants have been custom-built, but AMD allows plants to be built on skids with interchangeable components for faster builds.

HETI: Now that the Medora plant is online, what does the future hold? What are some of Archaea’s priorities over the next 12 months and beyond?  

SS: We plan to bring online around 15 RNG plants in each of 2024 and 2025. Archaea has a development pipeline of more than 80 projects that underpin the potential for around five-fold growth in RNG production by 2030.

We will continue to operate around 50 sites across the US – including RNG plants, digesters and landfill gas-to-electric facilities.

And we are looking to the future. For example, at our Assai plant in Pennsylvania, the largest RNG plant in the US, we are in the planning stages to drill a carbon capture sequestration (CCS) appraisal well to determine if carbon dioxide sequestration could be feasible at this site, really demonstrating our commitment to decarbonization and the optionality in value we have across our portfolio.

HETI: bp has had an office in Washington, DC for many years. Can you tell us more about the role that legislation has to play in the energy transition? 

SS: Policy can play a critical role in advancing the energy transition, providing the necessary support to accelerate reductions in greenhouse gas emissions. We actively advocate for such policies through direct lobbying, formal comments and testimony, communications activities and advertising. We also advocate with regulators to help inform their rulemakings, as with the US Environmental Protection Agency to support the finalization of a well-designed electric Renewable Identification Number (eRIN) program.

HETI: Science and innovation are key drivers of the energy transition. In your view, what are some of most exciting innovations supporting the goal to reach net-zero emissions?  

SS: We don’t just talk about innovation in bp, we do it – and have been for many years. This track record gives us confidence in continuing to transform, change and innovate at pace and scale. The Archaea Modular Design is a great example of the type of innovation that bp supports which enables us to pursue our goal of net-zero emissions.

Beyond Archaea, we have engineers and scientists across bp who are working on innovative solutions with the goal of lowering emissions. We believe that we need to invest in lower carbon energy to meet the world’s climate objectives, but we also need to invest in today’s energy system, which is primarily hydrocarbon focused. It’s an ‘and’ not ‘or’ approach, and we need both to be successful.

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
