U.K. REFUSE-DERIVED FUEL HEADED TO
SWEDEN FOR CHP
European secondary fuels specialist
Geminor has signed an agreement with
the government of Guernsey, U.K., an
island in the English Channel, to manage the export and recovery of around
20,000 tonnes of processed refuse-derived fuel (RDF) per year. The three-year contract, which commences in October 2018, will see RDF shipped from
Guernsey's waste transfer station at
Longue Hougue to the Jönköping Energi
cogeneration facility in Torsvik, Sweden,
as one of a group of Geminor's contracted offtakers that will recover the RDF.
The resulting renewable heat and power
will provide energy for thousands of
homes and businesses across the country. The agreement, which followed a
competitive tender process, has been
initially signed for three years, with the
option for a two-year extension. For

EMPOWER ANNOUNCES MOU,
COMPLE TES PLANT EXPANSION
Emirates Central Cooling Systems
Corp. (Empower) has signed a memoran-
dum of understanding with Ithra Dubai
to supply 11,000 refrigeration tons of
district cooling services to One Za’abeel,
which is being developed near the Dubai
World Trade Centre. The MOU was signed
by Ahmad Bin Shafar, Empower CEO, and
Issam Galadari, director and CEO of Ithra
Dubai, which is wholly owned by Invest-
ment Corporation of Dubai. The new
One Za’abeel building consists of two at-
tached towers – 67 floors and 57 floors –
piled on a retail platform with a suspend-
ed floor at a height of 100 m (328 ft).
This unique floor will be a link between
the two towers and will house Michelin-
starred and other fine restaurants. The
ground-floor retail podium, known as
The Gallery, is a three-story store with
several shopping and entertainment op-
tions. In addition, One Za’abeel will offer
upscale residential and duplex apart-
ments; commercial space designed for
prestigious offices and major corporate
headquarters; and luxury hotels for both
business and leisure travelers.
Empower also recently announced
the completion of the expansion at
its district cooling plant in the Dubai
International Financial Centre. The
62,000-ton plant is now one of the
largest district cooling plants operating
in the region. The 60 million Emirati
dirham ($16.3 million) expansion included adding six 3,150-ton ecofriend-ly Eco Wise centrifugal chillers by Trane.
The Ingersoll Rand Eco Wise portfolio of
products is designed to lower their environmental impact using next-genera-tion refrigerants with low global warming potential.
DATA CENTER TO FEED OSLO DISTRICT
As reported Aug. 14 by Max Smo-laks at datacenterdynamics.com, Nordic data center operator DigiPlex and
Fortum Oslo Varme are making plans
to recover waste heat from DigiPlex’s
Ulven campus in Oslo, Norway, for use
in Fortum’s district heating system.
The data center could produce enough
waste heat to warm 5,000 apartments in
the city. Norway’s largest district heating supplier, Fortum Oslo Varme will
also supply DigiPlex with chilled water
for cooling. The data center company
is already capturing waste heat at its
Stockholm facility for use by Stockholm
Exergi, a joint venture between Fortum
and the city of Stockholm. DigiPlex data
centers are powered using only renewable energy sources. To read the Data-center Dynamics article, go to https://
DOE: MORE THAN 550 MW OF NEW CHP
CAPACITY IN 2017
In August, the U.S. Department of
Energy’s Advanced Manufacturing Office
announced the release of the updated
CHP Installation Database, a comprehensive listing of CHP installations throughout the United States and its territories.
The project is a data collection effort
sponsored by DOE and maintained by
ICF Incorporated. The updated database
shows that there is a total CHP capacity
today of 81.3 GW installed at more than
4,400 sites around the United States and
its territories. According to ICF’s updated
calculations based off of new data, CHP
systems save the U.S. 1. 8 quads of fuel
each year, avoiding 241 million metric
tons of CO2 emissions annually.
Database users can search for specific CHP systems or groups of systems, sort
and filter data by categories, download
a list of currently operating CHP systems
and summary tables, and provide updated information on operating or retired
CHP systems. This year’s update includes
data through Dec. 31, 2017, and new
data on CHP systems in Puerto Rico and
the U.S. Virgin Islands. This new release
of the CHP Installation Database includes
the following highlights:
• There were 111 new CHP installations,
representing 554 MW of new capacity
• The states with the most new CHP installations were New York ( 53), New
Jersey ( 10), California ( 5) and Pennsylvania ( 5).
• The top three sectors were multifamily
buildings ( 32), systems at retail sites
( 14) and hospitals ( 13).
• The top two fuel types for new CHP
installations were natural gas (94) and
biomass ( 13).
• More than 39 percent of all new installations were smaller CHP systems
like microturbines and fuel cells.
These smaller systems are lower-cost
and more versatile than larger systems
and can be incorporated in new markets like the commercial and institutional sectors.
