Maston Group

What Maston Group does

Maston Group is a privately held, founder/family-owned renewable energy technology developer headquartered in Skutskär, Uppsala County, Sweden. Operating with a lean 5-person team, Maston develops patented technologies spanning four domains: solar PVT hybrid collectors (commercialized through subsidiary Solarus), bio-fuel turbine systems, Stirling motor components, and the Sunthetics solar-electrofuel (Power-to-X) process. The company's R&D is structured around the Maston Renewable Energy Lab (MREL), which participates in EU-funded international research consortia. Subsidiary Sunthetics AB owns the flagship Sunthetics B3C process — an integrated system that uses solar heat and power to drive continuous electrofuel production via CO2 capture from the atmosphere, steam electrolysis, and a patented methanol reactor featuring internal water-vapor recycling and multi-day thermal energy storage that allows day-and-night operation. The group also operates Maston SEAS, a PLC-based smart energy aggregator, and is currently extending its patent portfolio into thermal gasification of bio-waste.

Revenue model

1. Sunthetics Token Investment Offering: The Sunthetics token offering is available for a limited period through Brickken, providing investment opportunities in the company's solar fuel technology. This is a crypto/blockchain-based investment mechanism for the Sunthetics project.
2. Consulting Services: Maston provides consulting services including R&D advisory, IPR/patent consulting, product design, project management, advanced simulation, software development, manufacturing process development, and renewable energy lecturing. Services are delivered as expert resources for brainstorming, decision support, and advisory board participation.
3. Patented Technology Licensing: Maston licenses its patented technologies to industrial partners. The company has sold patents (e.g., hybrid solar collector to Solarus) and continues to commercialize technologies internally through Sunthetics while seeking partners to take other patents to market.
4. EU-Funded R&D Projects: Maston participates in international EU-funded research and development projects as part of Maston Renewable Energy Lab (MREL).

Core offering

Maston Group develops patented renewable energy technologies centered on the Sunthetics solar electrofuel production process, which combines solar PVT hybrid panels, atmospheric CO2 capture, steam electrolysis, and a patented methanol reactor with multi-day thermal storage for continuous day-and-night fuel synthesis. The company also licenses patent families (bio-fuel turbine, Stirling motor, hybrid solar collector) to industrial partners, runs the Maston Renewable Energy Lab (MREL) for international EU-funded R&D, and sells expert consulting in R&D, IPR, product design, advanced simulation, software development, and renewable energy lecturing.

Product overview

Maston Group is a portfolio of renewable energy companies that develops patented technologies for the transition to 100% renewables. The core offerings include Sunthetics, a patented electrofuel production process that converts solar energy into usable fuels through carbon dioxide capture, electrolysis, and methanol synthesis; the Maston Renewable Energy Lab (MREL) for internal R&D and EU-funded projects; consulting services spanning R&D, IPR, product design, and renewable energy expertise; and a collection of patented technologies including hybrid solar collectors, biofuel turbines, and Stirling motor systems.
