What are Integrated Energy Systems?

Power plants exist to make electricity, but most also produce a lot of heat. What if they could use that heat for other processes that require thermal energy? Today, roughly 40% of all energy is wasted. More efficient energy use would be better for the environment and for the plant owner. A power plant being used for both electricity and heat is called an integrated energy system. Integrated energy systems could couple nuclear, renewable and fossil energy sources. Such systems offer efficiencies that can lead to energy independence, economic competitiveness, job creation and smarter use of resources.

What are national labs doing?

The U.S. Department of Energy's Office of Nuclear Energy supports a national laboratory Integrated Energy Systems (IES) Program. The program conducts research, development and deployment activities to expand the role of nuclear energy beyond supporting the electricity grid. Expanded roles include supplying energy to various industrial, transportation and energy storage applications. Development of integrated energy systems may include multiple energy inputs (e.g., nuclear, renewable, and fossil), multiple energy users (e.g., grid consumers, industrial heat or electricity users, transportation fuel users), and multiple energy storage options (e.g., thermal, electrical and chemical).

​Using nuclear plants to generate heat as well as electricity for non-grid industrial applications could be central to deep decarbonisation efforts beyond being a source of zero-carbon electricity. Speakers at the fifth Atlantic Council Global Energy Forum last week looked at how hydrogen - and nuclear - can contribute to carbon abatement efforts in areas that have so far been hard to decarbonise.
