This is the premier gathering to learn about the latest developments in geothermal energy. Last year, the GRC Annual Meeting & GEA GeoExpo+ hosted over 1,200 attendees from over 25 different countries. The GRC Annual Meeting will offer technical, policy, and market conference sessions, educational seminars, tours of local geothermal and renewable energy projects, and numerous networking opportunities. The GEA GeoExpo+ features a unique opportunity for leaders in the business to showcase their projects, equipment, services and state of the art technology to the geothermal community. Reserve your booth now! There were more than 100 exhibitors at last year’s trade show.

6. On July 24, 1847, a wagon train of
pioneers arrived in the valley of the Great
Salt Lake. From the back of his wagon, the
Mormon leader Brigham Young, who was ill with
mountain fever, looked out at the vast desert
below and declared, "This is the right place"
The current inhabitants of Salt Lake City still
believe their city is the right place; they are
proud of their handsome city and welcome visitors from around the
world to enjoy its famous hospitality. There is still a pioneering spirit to
make their desert blossom and they have turned to renewable energy
to achieve this. Just over a year ago, Salt Lake City Mayor Jackie
Biskupski (who is slated to speak at the Opening Session of the GRC
Annual Meeting), announced an initiative to transition the community
to 100% renewable energy sources by 2032 and to reduce carbon
emissions citywide by 80% by 2040.
The geothermal community can certainly help Salt Lake City
realize this goal. At present, three geothermal developers; Cyrq
Energy, ENEL Greenpower and PacifiCorp produce 73 MW of
geothermal electricity, but this is only a small percentage of the
estimated 1300 MW of untapped potential in the state, enough to
power a third of Utah. However, that’s only part of Utah’s geothermal
story.
Utah has a long history of utilizing direct resources for space
heating, growing tropical fish and recreation. Geothermal water is
used to heat more than 25 acres of greenhouses in Newcastle, one
of the largest greenhouse complexes in the U.S., and 330,000 sq
ft of prison space. Spas and hot springs provide opportunities to
dive and swim in the thermal waters. In Grantsville, 40 miles west
of Salt Lake City, the adventuresome can swim with salt water fish.
Elsewhere, geothermal heat pumps are gaining ground with large
scale installations used to heat and cool school and church buildings.
Geothermal is making the Utah desert bloom.
This year's GRC Annual Meeting & GEA GeoExpo+ offers a
tremendous opportunity to learn about new advances in geothermal
energy and to rekindle relationships with geothermal colleagues.
More than 270 papers have been submitted for oral and poster
presentations, a number we have not seen in a decade. Papers
highlighting geothermal developments and investigations in more
than 30 countries will be presented.
This event remains the biggest in the geothermal energy
calendar. For over 40 years it has provided an opportunity for the
global community to come together to share and learn. Participants
will have opportunities to visit geothermal power plants in central
Utah and the geothermal wonderland of Yellowstone National Park
on GRC Fieldtrips. On Friday and Saturday prior to the start of three
full days of technical sessions, meeting attendees can participate
in workshops on Geothermal Resource Decisions and Operations
& Maintenance. The Geothermal Energy Association (GEA) will
host over 70 exhibitors at the GeoExpo+ and also joint sessions on
business and policy. The Opening Session of the meeting on Monday
morning will feature stimulating discussions on current geothermal
energy topics. An International lunch and session will provide the
latest updates from abroad. The social highlight will be ‘a Night at
the Museum’ - a fun networking event at the superb Natural History
Museum of Utah perched in the foothills above Salt Lake City.
For a full listing of the activities at the GRC Annual Meeting &
GEA GeoExpo+, I recommend going to the GRC website at https://
geothermal.org/meet-new.html for the latest information. There you
will find an Event Program you can download. Better still, download
the Event App to your mobile device for easy access to everything you
need to know (see page 2 for information on the Event App). For those
not attending the technical sessions, or are new to Salt Lake City, a
list of tours and sightseeing opportunities in the Salt Lake area can
be found on the website. If you have a few extra days, consider renting
a car and touring some of the national and state parks in Utah and in
the surrounding states.
