The Tech Tour Green Energy 2023 event brings together some of the most innovative and promising companies in the sustainable energy sector. This year's event featured several outstanding companies that are working to transform the way we generate and use energy.


One of the standout companies at the event was BeFC. BeFC is reinventing the way we power disposable electronics with eco-friendly paper-based biofuel cells for sustainable and practical energy generation. BeFC believes that their approach will not only allow for the replacement of batteries for existing applications but also open up new opportunities for low-power ultra-thin health monitoring and Internet of Things (IoT) applications.


Jolt Solutions is another company that caught our attention. Jolt is commercializing a high-volume industrial process to manufacture electrodes for use in H2 electrolysers and fuel cells. Their technology consists of a one-step method to produce self-supported electrodes in a continuous process in under 2 minutes, resulting in low-cost and durable electrodes that can help solve the critical production cost/device durability/device efficiency issues facing green hydrogen.


Vertoro BV is working to convert residual agricultural- and forestry residues into a lignin-rich oil platform, known as Goldilocks. Their technology is presently at TRL6, and a 1ktpa TRL8 demonstration plant was commissioned at the Brightlands Chemelot Campus in Geleen, the Netherlands, in Q4 2022. Vertoro counts LIOF, Brightlands Venture Partners, SHIFT Invest, and Maersk Growth as its investors.


ReMoni has developed a patented IoT technology platform that enables collecting and analyzing comprehensive real-time data on resource usage in a low-risk and low-cost manner compared to existing methods. Their platform covers power, water and water-based heating and cooling, and thus provides a good foundation for digitalization and energy efficiency.


Naco Technologies is empowering hydrogen systems through nanocoatings to prevent corrosion at 30% less cost compared to traditional approaches. Their coatings achieve the same productivity as chemical solutions, but are more robust and reliable, providing higher quality. With green hydrogen expected to grow extensively by up to 650x in the next ten years, Naco Technologies is well-positioned to make a significant impact in the sector.


Gen 2 Carbon takes carbon fibre waste, recovers the carbon fibres from that waste, and converts them into technical textiles for composites applications and reinforcements for thermoplastic and thermoset compounds. Their conversion processes result in products that are now in use in aerospace, automotive, wind energy, electronics, and clean energy applications.


Geyser Batteries Oy is a Finnish clean-tech start-up that is developing and producing a new generation of safe and sustainable power batteries using proprietary water-based electrochemistry. Their patented technology is set to be a game changer in the transition to 100% renewables-based power grids by providing fast-storage batteries with a minimal cost per charge, lowest-in-class greenhouse gas emissions, maximum safety, and ease of recycling.


Finally, NexWafe is designing, developing, and piloting a proprietary process to produce ultra-thin, high-efficiency, monocrystalline green solar wafers to make photovoltaics more sustainable and efficient. Their process is fully compatible with conventional solar cell manufacturing, making it a promising solution to increase solar efficiency and reduce costs.


Another company that stood out at the event was Turbit Systems, a company developing wind turbine blades made entirely of natural fibres. These blades have several advantages over traditional blades, including increased strength, reduced weight, and lower cost. Turbit's innovative approach has the potential to make wind energy more accessible and affordable for communities around the world.


Overall, those are the winners of the Tech Tour Green Energy 2023.
