ChemE in Environment, Sustainability and Energy

What do chemical engineers working in the environment, energy, and sustainability do?

Energy, water, food, and the environment are all interconnected. Chemical Engineers use their knowledge of physics, math, chemistry, materials & energy balances, thermodynamics, kinetics, and transport phenomena to sustainably provide the critical resources we need while protecting the environment from irreparable damage. This work involves transforming raw materials into useful products, generating energy, measuring contaminant concentrations, capturing emissions, and generally developing new processes to protect the planet. 

Innovations made by chemical engineers cut across energy sectors, the environment, and sustainability in all fields. From water filtration and treatment innovations, to more efficient photovoltaics and batteries, to increasing efficiency of all processes, chemical engineering produces cutting-edge solutions to today’s most pressing societal problems.

How does chemical engineering relate to the environment, sustainability, and energy?

Problems in the energy, environment, and sustainability space inherently involve a combination of molecular/chemical/materials science/physics behavior and process-level systems understanding. e.g. Solar energy generation is a cost-benefit analysis: it's not just about making a material that can absorb light. It's about making a device that can be created, shipped, and installed cost-effectively enough to warrant replacing silicon. In carbon capture, it's not just about making materials that absorb CO2. It's about creating a process that uses those materials and regenerates them in a cost-effective way, with sufficiently low energy that they consume less CO2 than they produce. Chemical engineers are also involved in developing new materials from sustainable sources aimed at reducing reduce waste without compromising on performance

Chemists create reactions. Chemical Engineers study whether those reactions can be performed efficiently enough to be worth implementing. Chemical Engineers design processes to make a reaction cost-effective enough to be competitive with existing technology. Chemical Engineers understand what happens to those reactants and products after they are used, and whether they can be easily disposed of later. Chemical Engineers design tools that allow those reactions to be performed at scale.

No other major/specialization combines this molecular-level understanding with the systems-level perspective.

ChemE and BSE are both good places for someone interested in process engineering and manufacturing of natural resources into fuels and products. Both majors provide the fundamentals of transport processes and process design. BSE majors focus more on the specific application of natural products chemistry, biomaterials, and bioconversion to develop products and fuels from renewable resources. ChemE majors have a strong foundation in the principles that underlie these processes but are less specialized on them and chemical engineers seek employment in a wider range of industries.

The two degrees are closely enough related that it is sometimes possible for highly motivated students to complete both degrees in a 5 year timespan. Students from both departments also frequently apply for master’s programs in chemical engineering.

Someone who is excited about computing will thrive in both disciplines. However, while CSE is about how computing happens, and ChemE includes aspects of this, the real focus of ChemE is on using tools like computing to solve problems that have a big impact on people’s health, climate and the environment. The scale of data available is a great fit for the systems perspective of chemical engineering and has the power to transform our future.

For example, ChemE’s use the tools of data science, machine learning and artificial intelligence to create new medicines, design and manufacturer clean energy solutions like space-age solar energy materials, and new ways to manufacture everyday products that use less energy, fewer non-renewable resources in a sustainable way. The tools of data science are embedded in a ChemE’s training, for ChemE’s need to know how to manage the data and computing needs of billion dollar semiconductor fabrication facilities with tools like Internet of Things and edge machine learning for real time process control.

Electrical Engineers and chemical engineers are both critical contributors to the emerging clean energy economy, but each plays different and complementary roles. Electrical Engineers are specialists in electrical power systems—how to connect, control, and deliver electricity reliably where it is needed—whereas chemical engineers are giving electrical engineers innovative and affordable new devices for generating, storing, and using electricity.

For example, chemical engineers are involved in battery formulation, manufacturing, and recycling, in the development (and recycling) of light weight composites for wind turbines, and manufacturing of energy efficient devices (like LED lighting) that have scaled globally in just a decade. Likewise, chemical engineers are responsible for reducing the carbon footprint of fuels used in transportation and electricity generation.

Someone who is excited by and cares about the environment and climate will thrive in both Chemical Engineering and Environmental Engineering. While these fields share many of the same fundamental concepts, environmental engineers tend to focus more on understanding how the world and its ecosystems behave, the role that humans play in affecting those ecosystems, and the technologies that can play a role in controlling or improving the environment. Chemical engineers tend to focus more on the chemical reactions taking place in those environments and the creation of new tools that can be used to study the environment or address issues affecting the environment. The knowledge that chemical engineers gain about chemistry, system processes, and materials allows them to see environmental problems from both a systems-level perspective and from the perspective of individual reaction events, and often rely on Environmental Engineers for a broader perspective on how those reactions or processes affect other aspects of the environment.

For example, chemical engineers are involved in wastewater remediation and treatment, carbon capture, recycling, soil remediation, the removal of toxic contaminants, oil spill clean-up, desalination, and toxic gas neutralization. Chemical engineers also have the opportunity to design new processes in the most environmentally friendly way. Environmental engineers help assess current and emerging risks to the environment and human health and work closely with civil and chemical engineers to create new remediation technologies which maximize benefit and mitigate detrimental environmental impacts.

What problems are chemical engineers trying to solve in sustainability?

Chemical engineers design, build and analyze processes that range in size and time, from the nano-scale to entire manufacturing plants that cover city blocks. ChemE's work on:

  • How can we scale up a process developed in a lab to reach as many people as possible?
  • Can we optimize this process to be more economical, environmentally friendly, and energy efficient?
  • How can we replace petroleum based products, including plastics, with plant-based materials that perform as well or better? 
  • How can we reduce waste and shipping weight by concentrating products without sacrificing quality or stability. 
  • How can we reduce pollution, including microplastics, and manage waste more sustainably? 
  • How can we improve energy efficiency, energy storage, and energy conversion for fuels and materials?
  • How can we improve carbon capture and storage and water availability technologies?

Customize ChemE to YOUR interests

ChemE is a cohort-based program, which means you never have to worry about when to take core classes or whether there will be space when you need it. You'll be able to focus on developing relationships with your classmates, faculty members, and advisers, as well as customizing your experience to your interests. While ChemE is a broad degree, we provide guidance to help students identify and pursue their interests while developing the strong fundamental perspective that all ChemEs bring. We encourage students to take ownership over their education to make the most of their time in chemical engineering.
