1) GENERATING POWER FROM NATURAL GAS PRESSURE DROPS

---

Spherical Rotors is pioneering technology that captures waste energy from pressure changes in natural gas pipelines and converts it into electricity. This innovation enhances operational competitiveness while reducing emissions. The expander is designed to independently manage pressure fluctuations and provide full flow control, positioning it as the world’s first power-generating gas control valve! Zero emissions operation electricity production is expected across a wide range of natural gas sites operated by producers, pipeline and utility companies.

Natural gas sites, unlike hydro-electric dams, typically face challenges converting pressure to electricity. Electrically operated valves meet emissions goals and comply with new regulator requirements which prohibit venting natural gas to operate valves. However, a gas site requiring 500W typically doesn’t have enough economic capacity or space for solar photovoltaic panels with sufficient battery backup to accommodate intermittent solar. Instead, gas is typically burned at less than a 3% efficiency for site power. Spherical Rotors’ patented rotary valveless technology is a bit like a screw compressor/expander, expect with a higher expected pressure rating, efficiency and adaptability to reliably generate the electricity required.

Spherical Rotors is focused on the successful development and commercialization of the first product.  This includes implementing the product across various types of natural gas sites as well as expanding sales across various jurisdictions.  

However, the technology is scalable and can be used across a wide range of compressor, expander, pump and control valve applications spanning global markets.  For example, advanced heat pumps may reduce driving range loss in electric vehicles and reduce emissions from heating both buildings and pipelines.

Spherical Rotors is a Calgary-based technology company that is reimagining how pressure, power & heat may be used or generated in various applications for savings & sustainability.  Starting at our headquarters in Calgary, Alberta, Canada, we want to use our innovative thinking and skills to solve global challenges.  

Spherical Rotors is committed to delivering high quality products that are proven to be reliable in their respective applications. Ansys® software helps us to get early insights to mitigate these risks.

The team is honored to receive generous support from individuals, industry and government to progressively de-risk our technology, reimagining what is possible! Successful completion of testing in a simulated environment will establish the operational confidence needed to advance to field pilot testing at committed producer and utility sites. NGIF Accelerator has been a key funding facilitator to connect project stakeholders. Thank you!
