About Our Centre

The Technology Access Centre for Energy and Environmental Sustainability (TACEES) is uniquely positioned to provide research expertise and facilities for the evaluation and advancement of technologies for the energy industry. Our goal is to ultimately enhance the economic and environmental performance of Alberta’s Energy and Mining industries. Through collaboration with industry, small- and medium-sized enterprises (SMEs), and other post-secondary institutions, we test novel approaches to energy and environmental sustainability challenges. Housed in a state-of-the art research facility, our team includes applied research scientists, engineers, technicians and students.

We are now a Technology Access Centre:

We have now joined a network of Canada’s 64 TACs across the country. TACs are specialized applied research & development centres affiliated with publicly-funded colleges.

What this means for our clients:

We now offer businesses different ways to collaboratively access our state-of-the-art facilities and multidisciplinary teams of experts that can turn innovative ideas into market-ready products.

Our goal is to help Canadian-based businesses, especially Small and Medium-sized Enterprises (SMEs) – to get their products, processes and services market-ready by:

  • Offering objective advice and specialized technical services;
  • Providing training related to new types of equipment and processes; and
  • Conducting applied research and development projects focused on company problems.

Our Commitment to Safety

At the Centre, we are committed to having a safe workplace for all of our staff, researchers, and visitors. We believe that safety is a top priority.

Why work with us?

Unique Ability to Leverage Funds

As an educational institution, we have access to various grants for Applied Research projects in Alberta and Canada.

Our Talent, Your Advantage

Applied Research is what we do best. Harness the power of our expertise and culture of partnership.

Active Involvement of Students

Trusted Industry Advisor

We identify specific industry challenges and mobilize knowledge to overcome them. We are a preferred provider of technology services for many of our partners.

Friendly Intellectual Property (IP)

Industry maintains and advances the IP to commercialize and remain competitive. NAIT does not retain any interest in the IP.

Leveraging partnerships with other institutions and centers

We are a collaborative research group and work with partners across Canada and other centers at NAIT. We are also a member of the TAC network, connecting with 63 other TACs across Canada.

Equipment Function


X-ray Diffractometer (XRD) Used for materials characterization such as crystal structure, physical properties of materials and thin film.
Atomic Force Microscope – RAMAN (AFM-RAMAN) Used to link the molecular information obtained by confocal Raman microscopy with the high-resolution surface information (structural and topographic surface imaging on the nanometer scale) acquired by AFM. Unique offering in Alberta.
Thermal Gravimetric Analyzer (TGA) Utilized for thermal analysis in which physical and chemical properties of materials changes with temperature, such as decomposition, degradation mechanism, thermal stability, oxidation, combustion.
Metro Carbon Residue Analyzer (MCR) Used for the characterization of coke formation tendency.
Organic Element Analyzer – CHNS Determination of organic elements – Carbon, Hydrogen, Nitrogen, Sulfur by combustion and Oxygen by pyrolysis.
Surface Area Analyzer – BET Ability to measure surface area of particles.
Laser Scattering Particle Size Distribution Analyzer - PSD Measures particle size distributions by measuring the angular variation in intensity of light scattered as a laser beam passes through a dispersed particulate sample.


Bruker Fourier Transform Infrared Spectrometer (FTIR) FTIR with fixed path; attenuated reflectance and diffuse reflectance cells for the analysis of wide variety of organic compounds, films and powders. Measurement of naphthenic acid content in process affected waters.
UV-VIS Spectrophotometer Analyze a variety of samples by conventional spectroscopy but advanced techniques can be implemented using the fibre optic accessory.
Wavelength Dispersive X-ray Fluorescence Spectrometer (XRF) Capabilities include elemental analysis in different kinds of samples: solids, liquid or powder.
