GTI’s early years undergo WWII turmoil and industry change

Founded in 1941—administered at the brink of World War II (WWII)—GTI was created by the gas industry itself.

At this time, most U.S. gas companies still distributed manufactured gas made from coal and oil, so it’s no surprise that GTI’s earliest projects involved research into the composition of fuel gases, the utilization of manufactured gas byproducts, and the development of improved gas production processes.

From the 1940s to 1960s, the gas industry was totally transformed from a supplier of manufactured gas to a distributer of natural gas.

  • 1941

    IGT opened its doors on June 3, 1941

    Founded by the gas industry and affiliated with the Illinois Institute of Technology (IIT), Institute of Gas Technology’s (IGT’s) mission was to specialize in research and education pertaining to the production, distribution, and utilization of gas and byproducts. Dr. Henry Heald was the first president of IGT.

  • 1941

    The world’s leading library on gas technology established

    From the beginning, IGT’s Technical Information Center (TIC) focused on the collection and dissemination of scientific information and today it is one of the world’s largest natural gas and energy technology libraries.

  • 1943

    The first Master’s degree awarded to a student in Gas Engineering

    A driving force behind the creation of IGT was the need for training graduate engineers for service in the gas industry. In the first decade, 35 men graduated from the academic program—33 with masters, and 2 with doctorate degrees. Later IGT began offering an undergraduate option for engineering students at IIT.

  • 1944

    Coal gasification a top priority

    IGT’s Basic Research Program began work on coal gasification and fluidization. Under C. G. von Fredersdorff and J.L. Johnson, sequentially, IGT grew in recognition as a world leader in the kinetics of coal gasification. IGT’s first patent on “Method of Carbonizing Coal with Iron Oxide” was issued in 1950, and IGT's pilot plant facilities expanded during the decade to permit more research with large-scale equipment.

  • 1948

    New building designed by Mies van der Rohe

    Larger facilities were needed, so a new modern building was designed for IGT by celebrated architect Mies van der Rohe. Peoples Gas Light and Coke Co. of Chicago also provided a 12,000 square foot site for IGT pilot plant facilities in the southwest part of Chicago.


Natural gas becomes a major fuel in the U.S.

The 1950s was a time of extensive construction of natural gas pipelines. Advancements in metals, welding, and pipe building made pipeline construction more economically attractive. After the war, the nation began building its pipeline network and natural gas became a widely used home fuel. Throughout the 1950s and 1960s, thousands of miles of pipeline were constructed throughout the U.S.

As manufactured gas was replaced by natural gas, GTI applied its expertise to new areas such as the fundamentals of natural gas combustion to ensure satisfactory performance of gas-fired equipment. GTI also became a pioneer in fuel cell research.

  • 1954

    Appliance testing for residential and commercial technologies

    By the mid-1950s, gas utilization research was a major activity, and IGT was equipped with sophisticated equipment and facilities, such as an insulated room for constant-temperature appliance testing and a combustion lab for studying flame phenomena.

  • 1955

    First digital computer in the gas industry

    Gas transmission and distribution work became prominent in the 1950s as natural gas replaced manufactured gas and extensive construction of natural gas pipelines took place. In 1955, IGT installed the first digital computer in the gas industry to help utilities solve gas distribution system design problems.

  • 1959

    Pioneering fuel cell work led to technology breakthroughs

    IGT became a pioneer in fuel cell research in the 1950s, first with phosphoric acid fuel cells, then with molten carbonate cells. IGT achieved many breakthroughs in performance, stack life, and manufacturing techniques, and received three patents by the end of the decade.

    A 200 kW phosphoric acid fuel cell—which incorporated technology advancements developed and tested in a GRI program—was introduced into the commercial building and light industrial plant market in 1991 by ONSI Corporation, and is now available in 400 kW units from Doosan Fuel Cell America. In 2003, GTI was selected by the U.S. Army’s Construction Engineering Research Laboratory (CERL) to head a team developing a portable, 10 kW electric generator powered by a solid oxide fuel cell for military applications.


Focus on coal and LNG resources

With the formation of the Organization of Petroleum Exporting Countries (OPEC) in 1960, the federal government began to explore abundant domestic coal resources as an alternative to oil. The U.S. Department of the Interior’s Office of Coal Research was founded to increase environmentally sound utilization of coal, and funding in support of coal gasification research increased from government and industry.

LNG first entered the world market during the 1960s, when France began importing LNG from Algerian gas fields. By 1971, U.S. companies began importing too.

IGT experienced rapid expansion and growth—research revenue totaled $41.8 million, staff reached 100 employees by 1961, and IGT was awarded 146 patents during the decade.

  • 1967

    Eternal Flame at the John F. Kennedy Memorial created by IGT

    IGT created and patented the specially designed “eternal flame” burner for JFK’s permanent gravesite in Arlington National Cemetery.

  • 1969

    First coal gasification plant to produce substitute natural gas on stream

    IGT completed the construction of a $30 million coal gasification pilot plant by the end of the decade, the culmination of research work that had been underway for 25 years.


Rapidly escalating global energy issues drive energy independence

The National Environmental Policy Act, the Environmental Protection Agency (EPA), and the Clean Air Act—all coming in 1970—kicked off a decade of environmental policy-making. In 1973, the energy crisis made front-page headlines and fears of future energy supply shortages loomed in the U.S., driven by the OPEC oil embargo and civil unrest in major oil exporting countries.

Energy independence became a goal of national policy, marked by strong actions to stimulate new gas production from unconventional gas resources and initiate alternative or synthetic fuels development. In 1977, the U.S. Department of Energy (DOE) was activated as various federal government agencies focused on energy functions were consolidated for a sharper focus.

IGT realized continued growth during the decade with performance surpassing records in all categories: research progress, revenue, employment, facilities, development, and educational achievement.

  • 1970

    World speed record set by the Blue Flame natural gas racecar

    The LNG-fueled Blue Flame was a high-performing, ultra–high-speed, rocket-powered vehicle, which set the world land-speed record of 622.407 mph in 1970—a mark that stood for 13 years. IGT managed the design, construction, and formal racing of the car, fueled by methane and utilizing hydrogen peroxide as an oxidant.

  • 1973

    U-GAS® gasification technology created syngas from coal

    An extensive program to develop and scale-up coal gasification processes was initiated. IGT’s U-GAS® technology efficiently converted all ranks of coal into high-value synthesis gas, and IGT was awarded several patents on the process.

  • 1976

    Gas Research Institute (GRI) established

    GRI was created as an overview organization to manage a cooperative research and development (R&D) program that benefitted the gas industry and ratepayers and was funded by a FERC-approved surcharge. Dr. Henry Linden, the head of the IGT for 17 years, was instrumental in GRI’s establishment, and became the first president. Dr. Bernard “Bernie” Lee took over as president and CEO of IGT in 1978.

  • 1978

    Training and education around the globe

    A Chartered Industrial Gas Consultants certification course series was initiated. From 1978 to 1990, IGT was involved in the administration of the Career Development Center in Abu Dhabi, established an Algerian gas institute, and conducted LNG courses in Venezuela, Germany, and Indonesia. In the 1990s, IGT developed a long-term training plan for the Korean gas industry and hosted programs for Korean gas company personnel.


Declining oil prices and energy conservation

World oil prices collapsed in the middle of the decade. Drilling hit a new low and many energy companies sharply cut exploration budgets and laid off staff.

During the 1980s, GRI made huge strides in advancing unconventional gas production processes, developing new tools and knowledge to increase the amount of recoverable gas while reducing production costs.

In 1987, The National Appliance Energy Conservation Act is signed into law by President Reagan, requiring manufacturers to make their products more energy efficient. Timely introduction of new technologies capable of containing the cost of gas use becomes an increasingly urgent priority, and GTI refocuses efforts to make high-efficiency gas equipment available across end-use markets.

  • 1980

    PE plastic pipe and piping product expertise

    With work from the 1980s through the early 2000s, GRI confirmed the suitability of polyethylene (PE) plastic pipe for gas distribution systems with research, development, testing, and technology advancements. New equipment, tools, instruments, techniques, and guidelines for safe and efficient installation and maintenance of plastic pipe and more than 300 reports, technical papers, software, and studies on plastic pipe topics were created.

  • 1982

    Home heating market revolutionized

    The Pulse Combustion Furnace was the first major change in gas furnace design in over two decades, and resulted in significant gains, delivering operating efficiency that exceeded 96%. GRI funded development and field testing, and Lennox Industries, Inc. commercialized the technology. It became one of their most successful products, and over one million units were sold between the early 1980s and mid-1990s.

  • 1982

    New collaborative research model launched for coalbed methane production

    In 1982, GRI led efforts to develop unconventional gas resources. Working with about 40 other organizations, GRI documented regions with the greatest potential and developed guidebooks, simulators, and other tools to explore options for fracturing a coal formation and optimize operations to make resources cost-effectively recoverable. Strong industry involvement in field experiments was critical to the success of the program, and the research investments from GRI and DOE sowed the seeds of unconventional gas production far into the future.

  • 1983

    Hydraulic fracturing research began

    GRI’s hydraulic fracturing research began as early as 1983, leading to “proof-of-concept” experiments at the first hydraulic fracture test site (HFTS) in the Rocky Mountains. A multitude of leading-edge breakthrough technology was verified, improving the industry’s understanding about the fundamentals of hydraulic fracturing.

  • 1985

    Sustaining Membership Program (SMP) founded and environmental technologies took center stage

    In response to government cutbacks, IGT turned to membership to build greater support for the gas industry’s technology base and meet future needs by founding the SMP, focused on collaborative research.

    Environmental research was a key technology development area, and IGT received two important patents. The SOLCON Digester, an anaerobic digestion process, was tested at Walt Disney World and performed 80% conversion of biomass to methane. The Methane Enrichment Digester technology produced utility-grade gas from a pilot-scale anaerobic digester, also demonstrating successful results for renewable energy production.

    In the early 1990s, SMP funded the development of a suite of remediation technologies—MGP-REM, PCB-REM, and thermo-chemical solidification—that reduced cost of management of manufacturing gas plant (MGP) legacy sites by more than 50% and addressed contamination, toxicity, and organic pollutants in surrounding soils, sediments, and water.

  • 1987

    Dr. Stephen Ban became leader of GRI

    Dr. Stephen Ban became the President and Chief Executive Officer of GRI in 1987 and served in that role until 1999.


An upward shift in environmental, a downward shift in funding

With the environment a top priority, IGT and GRI assisted companies with attaining compliance with EPA ozone and carbon monoxide standards. Innovative burners and combustion systems reduced critical emissions and increased heat transfer cost effectively, positioning gas very favorably in the industrial sector, and new high-efficiency space conditioning equipment helped develop a niche for gas in this traditionally electric market. NGV research exploded. Alternative fuels, cogeneration, and the disposal of the ever-growing volumes of sewage waste were also key topics.

The 1990s were also called the “value decade.” Customers demanded more for less, and excess capacity and global competition prodded companies to find ways of adding value to their products without adding cost. DOE was realigned, R&D spending by government and industry was reduced, and funding was focused on short-term commercialization efforts.

  • 1991

    New technology expanded production rates by an order of magnitude

    GRI research on shale formations in Illinois and Texas was key in developing horizontal drilling. Researchers worked with Mitchell Energy to drill a horizontal well in the Barnett Shale stimulated with new technology that produced three times more gas than any other well up to that time.

  • 1991

    R&D and commercialization efforts led to significant NGV market penetration

    GRI supported development of a multitude of NGV engines and vehicles capable of meeting stringent vehicle emission standards. Researchers also pioneered advances in cylinder safety and materials for lighter-weight, on-board CNG storage cylinders. Since then, GTI has assisted Cummins Westport, Inc (CWI) in developing and demonstrating a number of medium and heavy-duty NGV engines. More than 27,000 8.9L Ultra-Low Emissions NGV engines for transit, refuse collection, and regional hauling applications have been sold since introduction in 2007.

  • 1992

  • 1999

    Gas burner technology for lower NOx emission

    In the late 1990s, GRI and IGT made significant contributions to the industrial sector, with more than 65 patents on high-efficiency, low-NOx burners and systems to control emissions. One of the most successful GTI-developed burners on the market is the PrimeFire 400 high-luminosity burner from Eclipse that increases heat transfer rate and reduces NOx emissions by 50%.

    Burners have also played a key role in delivering efficiency to commercial foodservice applications. Researchers developed a new fryer burner design for Pitco, ushering in the era of energy efficient fryers common today. GTI also pioneered the use of modulating burner technology in Avantec conveyor pizza ovens to reduce temperature variations, saving energy and improving food quality.


Innovation and investment for a clean energy future

Following worldwide Millennium celebrations, 9/11 changed the tone of Y2K, followed by Hurricane Katrina. The Great Recession, a major worldwide economic downturn, began in 2008. The natural gas industry moved from a tight supply and demand balance with extremely high gas prices to an easing one with plummeting gas prices.

The energy industry was faced with mergers, acquisitions, cost-cutting, and downsizing. As a result, many companies were forced to curtail their in-house R&D activities, and GTI played an important and valuable role in filling that void.

With an era of challenges and opportunities, GTI creatively delivered innovative solutions to help meet the nation’s needs with clean energy technology.
