Perryman Thermal Battery—with a Molten Nickle/Iron Core. Is this the Future
of Thermal Storage?



Date: Friday, April 14, 2017

Time: 8:00am – 10:00am

Organizer: Gelvin Stevenson, PhD

Host: Sidley Austin LLP

Location: 787 Seventh Ave. (AXA Equitable Building, between 51st and
52nd Streets),
23rd Floor



Thermal Energy Storage gets no respect. At least not the respect it
deserves. But thermal storage has been used for over a century and works
extremely well. It has the lowest cost per kilowatt, the smallest volume
per kilowatt—or, conversely, the highest energy density—of any energy
storage technology.



Perryman Thermal Battery is poised to earn that respect.



Chemical Engineer Virgil Perryman has spent over six years developing and
testing his technology. He has been granted two patents and applied for
another one. The British Ministry of Defense tried considered his
technology in its early years to be used by the British forces in
Afghanistan, including a half scaled 13-ton unit that can powered command
control for a forward base, a front line surgical unit and radar. They
tested it for several years using heat generated by both solar thermal
arrays as well as charging from AC or DC sources. The storage unit was then
used to generate both heat and electricity as needed. Mr. Perryman
originally build an 30 ton initial prototype in 2010 which stored up to 10
MW of thermal energy and subsequently improved the technology so the same
containment could store 29.9 MW of thermal energy and could produce 10 MW
hours of electricity and 18 MW hours of thermal energy, idea for situations
where heat and power are needed. Currently, a European group (which cannot
be named) is testing Perryman Thermal Batteries as back-up generators for
wind and other intermittent energy generation sources. After 16 months of
testing one system where energy must be stored for over 180 days, the units
are preforming flawlessly.



The company plans to start installing its thermal batteries later this
year. Mr. Perryman has developed one model about the size of a large home
hot water unit; another is about half that size and is targeted for homes
in the United Kingdom. The first commercial installation is set for a new
green residential development England where construction is about to start.



It’s no surprise that the technology works; it is, after all, based on a
technology that’s been around way longer than humans. The battery stores
energy the same way the Earth stores energy—making it rather like your
ultimate bio-mimicry technology. The earth has a molten metal core that’s
over 10,800 degrees Fahrenheit. That’s about as hot as the sun! But the
surface of the earth is about 60 degrees F. Why? Because of the multiple
layers of refractory material between the core and the surface.



The company uses off-the-shelf magnetic induction to melt the nickel-iron
core, which is surrounded by a special shield, which is surrounded by an
alumina layer and layer of material very similar to the tiles used on the
Space Shuttle tiles, a very efficient ceramic refractory which literally
holds the heat in. Then there are more layers of ceramics of different
density, all designed to trap the thermal energy, and finally a layer
similar to the insulation you would find on your kitchen oven. The outside
enclosure can be customized to various applications and for inside or
outdoor use. Finally, the unit’s outside layer is warm to the touch (about
90 degrees F) but not hot; rather like the cooling fins on the back of a
refrigerator. It is controlled by a touch pad with a remote-control option.



This is a proven technology, going back at least for 100 years. It has been
used in the UK and throughout Europe. The Storage units can be safely
transported by road, rail or sea, either un-charged or fully charged with
100 tons of molten steel and 29 MW of thermal energy.



It is a global battery, with the core from Austria, thermal transfer system
from Germany, the controls from several suppliers including the USA, UK and
Japan, and, finally, the closed loop steam generator from suppliers
worldwide to allow local servicing and maintenance since it’s the only
component with moving parts. While the supply chain may be complicated, the
technology is simple.

Perryman Energy Storage Batteries compare very favorably with other battery
technologies. They store roughly 10 times as much energy as Elon Musk’s
Powerwall lithium-ion batteries (that have roughly a 10kWh storage
capacity) and will cost half as much. Moreover, Perryman will offer a 10
year warranty. The company believes, however, that the battery will run 100
years and the steam turbines will last 30 years or more with proper
maintenance. The company claims that the core, which is “solid state”,
won’t run out; only the control system may need updating with the will the
thermostat may have to be replaced periodically. The steam
turbine—depending on the brand selected from country to country—can last a
half of century without replacement.



In addition, the Perryman Battery bests Lithium Ion batteries because they
last longer, are not poisonous, do not start fires and do not pollute.

The original cost will be about $13,500 each. They expect that to fall to
about $6,000 each when they get to an annual production level of 10,000
units per year. This cost is way lower than competitors. Perryman Batteries
cost $80/kW compared to $600/kW for molten salt, $250/kW for lithium ion,
$320/kW for lead acid batteries and $500/kW for flow batteries.

The company is currently working on a plan to offer the DC Metro (the
Capitol’s subway system which consumer a huge amount of electricity) a
solution that may reduce operating cost to a sustainable level. They are
proposing to store cheap electricity during the off-peak periods and
resupply during peak periods as well as provide thermal energy for Winter’s
heating and drive absorption chiller for air conditioning in the Summers,
all while cutting costs by 60%.

     Virgil Perryman is the founder and inventor of Perryman Technologies.
Virgil has had an extensive career that has culminated in the development
of key patents in the areas of collection, storage, and application of
thermal energy. These patents protect the technology used in the Perryman
Troughs, Dishes, Perryman Micro Panels, Perryman Battery™, Non-Combustion
Gas Turbines and the many globally important applications of these
technologies.



     Virgil’s technical specialty is the science of how elements behave and
interact at very high temperatures. This has led to the ultimate energy
storage system; the Perryman Battery™, which uses metal with high heat
capacity in its molten state and can store in the larger batteries billions
of joules of energy. Further, it can store this energy for months if not
years until required. Virgil has also developed a reflective film that
captures energy from both visible light and thermal from the infrared
spectrum that can heat the metal in the battery to around 1650oC. Virgil’s
full spectrum collectors can operate economically in nearly all locations
globally, and certainly in many areas of the planet where conventional
solar thermal and PV just does not work. This technology can be used to
provide clean, renewable, low-cost energy for electricity, heating,
cooling, water management, transportation, food and material production and
many other applications which will have a positive impact on nearly every
aspect of human life.

financings as well as merger and acquisition activity, both in the US and
abroad. He has worked extensively in China, and has conducted due diligence
on dozens of portfolios of distressed bank loans and other assets in China,
Hong Kong, Korea, and Indonesia.


He has been instrumental in the development of several new financing
structures, from credit enhancement work in the New York capital markets,
to zero-coupon loan facilities in London and New York. He has worked
extensively as a corporate lawyer, consultant and lecturer in the fields of
technology start-ups (robotics, telecommunications, materials applications
and AI) and commercialization of low-earth orbit activities, and served on
the Commercial Advisory Subcommittees for NASA.

which enable such bodies to engage in commercial activities worldwide in a
non-taxable vehicle, Mr. Austin also has experience in trademarks and
copyright protection disputes. In this regard, he represented US based
group of International Association of Motion Pictures Exporters, Porsche
and other companies.
