TBB2026 Investor Track 200 leading clean tech investors gather in one place

TBB is InnoEnergy’s yearly event, gathering its ecosystem to discuss current trends, investment cases, and create new opportunities together. InnoEnergy’s 120+ VC Community members gather once a year for a pre-TBB meeting. This year, the meeting is open to everyone with an investor track pass.
Being part of the InnoEnergy ecosystem has always been of good value to our activities, not just as a qualified deal flow source but also because of its systemic role. InnoEnergy is one of the few early-stage pan-European cleantech players and has been committed to the sector for over 15 years. It makes them a structural element of that ecosystem. And of course, as an earlier stage investor, InnoEnergy nurtures and grows opportunities that come later to our growth stage focus with a differentiated quality stamp – article 9 qualified, management teams aware of requests and asks of investment funds, reporting standards, etc.

High purity and quality PV recycling with 90% impact savingsROSI

ROSI’s recycling process, which extracts high-purity raw materials from end-of-life PV panels, has proven to have a 90% impact savings compared to conventional production activities. The recycling process keeps the raw material’s purity high, creating new and locally available secondary raw material sources. End-of-life PV modules are expected to reach 78 million metric tonnes globally by 2050. Around 1900 GW of PV capacity is installed worldwide, with an annual average of a 20% installation growth rate. PV panels installed 20-30 years ago are beginning to reach their end-of-life and need to be replaced. Recycling them provides a tremendous opportunity to reuse raw materials such as copper, silver, aluminium, and the critical raw material silicon, reducing emissions and boosting Europe’s resource independence. ROSI’s proprietary technology recovers up to 99% of precious materials, such as silver and ultra-pure silicon, from discarded photovoltaic panels, far exceeding current recycling norms. The first recycling plant in Grenoble, has proven ROSI’s recycling process and closed the commercial value chain. Automation will further reduce the cost. With the developments and being first of a kind, delivering substantial ESG impact, ROSI plays a crucial role in closing the loop for the PV industry.

50% higher water recovery with 30% lower energy useStockholm Water Technology

Stockholm Water Technology’s (SWT) patented electro-capacitive water cleaning technology includes software-tailorable water quality capabilities. This significantly reduces the energy consumption for water treatment and generates unprecedented application-specific flexibility. It is also common for SWT products to have up to 50% higher water recovery, 30% lower energy use, massively reduced chemical usage, the capability to recover nutrients from waste, and complete autonomy in operation, which brings lower OPEX costs. The serviceable obtainable market (SOM) for SWT in phase 1 (until 2030) is approximately €27B, spanning the industrial, municipal, and consumer markets. Phase 1 is focused on building sales and customer success traction in Europe, the Middle East, and India for wastewater recycling in inland fish farms, municipal wastewater plants, and specific industries. This phase will also focus on capturing a good portion of the consumer and commercial market in the Middle East and initial traction in the Indian market. Moving into phase 2, SWT will serve municipal and industrial projects with an SOM of over €50B, with planned expansion into the Americas. After the successful commercial deployment of the smaller STRÖM unit in 2022 and building in-house manufacturing expertise, SWT is now scaling up and introducing its larger system, FORS, to service the needs of medium industry and small municipality projects. SWT is also working on automating and increasing its production capacity to meet projected sales requirements in the coming two years. By Q4 2026, the full-scale industrial system will be introduced, capable of serving municipal-level applications on a global scale.
