Fredericton-based Anessa, which makes software for the biogas industry, has announced partnerships with two major French energy companies, TotalEnergies and CVE Biogaz.

Founded in 2017 by chief executive Amir Akbari and chief technology officer Dr. Farough Motasemi, Anessa develops software that supports biogas developers and operators from early-stage project assessment through to plant operations. Its platform enables companies to model proposed facilities, estimate costs and carbon impacts, and optimize performance once plants are running.

Under its agreement with TotalEnergies, Anessa is providing software for a new internal digital solution known as Starck. The platform is designed to standardize how TotalEnergies evaluates, designs and optimizes biogas plants. By using an integrated software system, the French energy company aims to streamline development studies and apply a consistent methodology across projects.

Starck models biogas processes at a conceptual level and incorporates business and operational parameters, including cost estimates and carbon impact assessments. The companies said they intend to continue developing additional features for the platform as operational requirements evolve.

TotalEnergies is France’s largest energy company, operating in more than 120 countries and employing more than 100,000 people.

In a separate announcement, Anessa said it has entered into a long-term strategic partnership with CVE Biogaz. Under that agreement, Anessa’s modelling and analytics platform will be deployed across CVE Biogaz’s existing and future facilities.

CVE Biogaz is a subsidiary of the CVE Group, an independent French renewable energy producer. The subsidiary operates 16 methanization units, with four additional sites under construction, and has close to 20 projects in development. It employs about 140 people and operates across the biowaste and biomethane value chain, from waste collection to gas production and the return of organic matter to soil.

Anessa’s software includes digital twin technology and AI-enabled optimization tools that allow operators to simulate plant performance, test scenarios and monitor assets in real time. Through the partnership, CVE Biogaz will use the platform to support project design, operational monitoring and performance optimization across its portfolio.

Both partnerships mark an expansion of Anessa’s presence in the European market. The company said the collaborations are intended to support more efficient project development and plant operations through standardized modelling, data analysis and performance tracking tools.
