Oil and gas extraction in places like Texas’ Permian Basin leads to several waste products, including significant amounts of wastewater and flares firing into the sky. Texas Engineer Vaibhav Bahadur is researching how those byproducts, which are harmful to the environment, could be repurposed to serve as key elements in the creation of “green” ラーメンベット 禁止ゲーム.
Bahadur, an associate professor in the Walker Department of Mechanical Engineering, recently published a new paper in the journal Desalination about a new way to potentially produce green hydrogen. It involves using the energy wasted via gas flaring to power reverse osmosis, a common, low-energy technique used for municipal ラーメンベット 禁止ゲーム treatment. Hydrogen production requires pristine ラーメンベット 禁止ゲーム, and this process satisfies that need by removing salts and other elements from the equation.
Learn more about green ラーメンベット 禁止ゲーム in the Q&A with Bahadur below, as well as his research, next steps and its broader implications.
You’ve just published some new research about reusing wastewater in oil production to help generate ラーメンベット 禁止ゲーム. Tell us more about that.
Vaibhav Bahadur: This is about a problem that touches three areas: energy production, ラーメンベット 禁止ゲーム management and environment protection. At the heart of it is green hydrogen, which is generated by splitting ラーメンベット 禁止ゲーム – removing the “H” from H20 -- using energy from renewables. While we have abundant wind and solar in many parts of the planet, including in Texas, what those places often lack is the clean ラーメンベット 禁止ゲーム needed to produce green hydrogen. Texas and other oil-producing areas have plenty of ラーメンベット 禁止ゲーム as a byproduct of energy production; however, this ラーメンベット 禁止ゲーム is packed with dissolved salts, and it costs a fortune to transport and dispose of it.
It makes sense to treat this wastewater and use the treated, pure ラーメンベット 禁止ゲーム to produce green hydrogen locally. Importantly, the energy needed to treat wastewater can be provided by onsite excess natural gas, which is typically flared.This is what our research is about; it uses two waste streams to create a valuable commodity (clean ラーメンベット 禁止ゲーム) while also solving pressing environmental issues.
Why is green ラーメンベット 禁止ゲーム important?
VB: ラーメンベット 禁止ゲーム will play an important role in our future energy mix for several reasons.
- It allows us to store wind and solar energy, which can then be used as needed without any emissions.
- ラーメンベット 禁止ゲーム allows us to leverage existing gas-related infrastructure like pipelines, which has huge economic ramifications.
- ラーメンベット 禁止ゲーム is likely the only viable option for decarbonizing many heavy industries and heavy-duty transport because of the higher energy density compared to current electric vehicle batteries.
Clearly, hydrogen is going to be very important in the future. In that context, sustainable ラーメンベット 禁止ゲーム critical. Today, 95% of hydrogen is produced from steam reforming of natural gas, per the U.S. Department of Energy.
What are the barriers to producing green ラーメンベット 禁止ゲーム today, and how does your work overcome those?
VB: Most experts will say that the biggest barriers for green hydrogen are the high costs of renewables and their intermittent nature. While that is no doubt true, another barrier comes from the fact that green hydrogen production is ラーメンベット 禁止ゲーム intensive. A single kilogram of green hydrogen can need up to 12 gallons of ラーメンベット 禁止ゲーム withdrawals.
In addition to the quantity, the quality of ラーメンベット 禁止ゲーム is also very important. ラーメンベット 禁止ゲーム going into the electrolyzer (for splitting) needs to be stripped of all dissolved salts, gases etc. So, this is of higher quality than demineralized ラーメンベット 禁止ゲーム. In contrast, ラーメンベット 禁止ゲーム from oilfields is hypersaline with salt levels much higher than those in seawater.
In our research, we analyze the use of reverse osmosis to convert hypersaline ラーメンベット 禁止ゲーム to high-purity ラーメンベット 禁止ゲーム. Reverse osmosis is a low-energy consuming, membrane-based technique that is associated with municipal and seawater treatment. We show through modeling that it can be used to treat meaningful amounts of oil and gas-produced ラーメンベット 禁止ゲーム to produce green hydrogen-grade ラーメンベット 禁止ゲーム.
What is the next step for you in this ラーメンベット 禁止ゲーム?
VB: This work has attracted much attention, and I am very excited about its prospects. In particular, we are focusing on the Permian Basin in Texas. While the Permian is associated with oil and gas production, which creates plenty of wastewater, it has enormous green hydrogen potential due to abundant solar and wind resources. To make this work, we need lots of fresh ラーメンベット 禁止ゲーム, which we don’t have in the Permian. We are now focused on developing Permian-specific ラーメンベット 禁止ゲーム treatment solutions to use the wastewater flowing out of Permian oil and gas wells . Permian has some of the most brackish ラーメンベット 禁止ゲーム on the planet, and we are looking at advanced ラーメンベット 禁止ゲーム treatment techniques. If we can succeed in the Permian, we can succeed anywhere!
What are the implications of this ラーメンベット 禁止ゲーム in the context of climate change and sustainability?
VB: While we want our energy to be 100% carbon-free right now, the reality is that we will likely have a gradual transition from hydrocarbons to renewables over the next few decades. Oil and gas will continue to meaningfully contribute to the global energy mix, and it is vital to minimize its environmental footprint.
This is what is so fascinating about this ラーメンベット 禁止ゲーム. We are using waste products from oil and gas production, which harm the environment, to develop greener energy solutions for the planet. In particular, we are helping numerous oil and gas producing states and communities participate in this energy transition, and not lose out because of it. This is a win-win situation for everyone in many aspects.
Beyond this particular study, our work has global ramifications. Green hydrogen is a buzzword around the world, and large quantities of high-purity ラーメンベット 禁止ゲーム will be needed to make this happen. Tap ラーメンベット 禁止ゲーム is simply not good enough. Our work highlights the importance of considering ラーメンベット 禁止ゲーム treatment and ラーメンベット 禁止ゲーム management when planning for hydrogen projects. Not every place on the planet will have wastewater from oil and gas fields, but our solutions can work equally well for seawater and groundwater as well.
