As we move toward a decarbonized economy, hydrogen has the potential to be an alternative fuel for power generation, transportation and industrial production. Kiewit’s experts understand what it takes to produce, handle, transport and store hydrogen safely. We have experience executing a variety of hydrogen projects, from front-end engineering and design (FEED) to the construction of fueling stations and hydrogen plants. Additionally, our decades of experience in power generation systems, refineries and midstream transportation networks facilitates effective and efficient partnering with technology licensors and OEMs to deliver your project.
Battery Energy Storage
Kiewit can design, build and integrate a variety of battery energy storage solutions, from modular battery systems to purpose-built structures, to meet your specific needs. As an EPC contractor, our expertise encompasses the entire project lifecycle. Because we understand all aspects of energy storage including the required HVAC and fire suppression systems, we produce realistic, reliable cost estimates.
Kiewit offers scalable, local teams who have experience with complex civil, power, and industrial facilities and knowledge of your region’s particular complexities and constructability opportunities. Our engineering teams offer full design services including electrical and mechanical engineering with the capability to design large turbines and pump houses — along with all the construction components required to deliver them. As an EPC contractor with broad hydropower experience, we offer reliable estimates, project schedules and ultimately cost certainty.
Grid-Scale Energy Storage
Kiewit provides design and construction services and expertise for emerging storage technologies including the following:
Currently the most common energy storage method for large concentrated solar power (CSP) plants, molten salt offers a cost-effective and reliable solution to fluctuations in renewable resource availability. This technology can be readily integrated into various applications and is a proven low-cost option for energy storage.
Liquid air energy storage (LAES) stores liquified air, then returns it to a gaseous state by exposing it to ambient air or process waste heat. The reconstituted gas turns a turbine to generate electricity. LAES systems (or cryogenic energy storage (CES)) are low-risk investments well-suited to long-term applications since they use off-the-shelf components with long life spans.
With higher energy storage density, a carbon dioxide system offers a possible solution to address captured carbon. This type of system compresses CO2 into a liquid state and pumps it into a deep, high-pressure saline reservoir. When energy is needed, liquified CO2 is released into a shallower, low-pressure reservoir, spinning turbines to produce power.
