International Workshop on Carnot Batteries
October 9–10, 2018, Stuttgart

Keynote Lecture by Nobel Laureate Professor Robert B. Laughlin, Stanford University, author of the book “Powering the Future”


Carnot Batteries are an emerging technology for the inexpensive
and site-independent storage of electric energy at the gigawatt
hour scale. Also referred to as “Pumped Thermal Electricity
Storage” (PTES) or “Pumped Heat Electricity Storage” (PHES), a
Carnot Battery transforms electricity into heat, stores the heat in
inexpensive storage media like water or molten salt and transforms the heat back to electricity when required.
Carnot Batteries have the potential to solve the global storage
problem of renewable electricity in a more economic and environmentally friendly way than conventional batteries. Although several concepts have been proposed for Carnot Batteries, there exist
neither a comprehensive techno-economic assessment of this
technology nor laboratory or plant scale demonstration facilities
that provide the energy storage community with scientific data.
The first goal of the workshop is to bring together experts in
energy storage, in particular thermal energy storage, in order
to assess the state-of-the art of research and demonstration of
Carnot Batteries. The second goal of the workshop is to establish
an international platform that coordinates research in Carnot
Batteries and makes it internationally visible.
The workshop will be opened by a keynote lecture by
Nobel laureate Professor Robert B. Laughlin (Stanford
University) - author of the book “Powering the Future” -
who initiated Google-X’s Malta project. Invited lectures by
Dr. Toru Okazaki (IAE Tokyo) and Professor Yulong Ding
(University of Birmingham) will review the development of
Carnot Batteries in Japan and UK, respectively
