Top 10 Clean Energy VC (Venture Capital) Funds in Sweden in May 2026

Portfolio highlights

• ecoLocked — ecoLocked is your partner to create a climate-positive built environment. We develop CO2-optimized recipes for concrete based on carbon-negative biochar admixes. Our admixes allow to store captured CO2 in buildings, reduce direct emissions from concrete production, and provide multiple functional benefits, such as improved thermal insulation.
• Entocycle — Entocycle is developing the world’s most efficient and sustainable way to produce protein. The rainforests and savannahs of South America are being destroyed at shocking rates in order to grow crops such as soy to feed farm animals. Using insects to feed livestock requires significantly less land and water compared to soy whilst being a naturalpart of the diet for many animals including fish, chickens and pigs. Their technology is significantly more efficient at producing protein than traditional methods of production as their insects are vertically farmed and not restricted to floor space or area. Thanks to their automated system they can produce at industrial scale and offer farmers a cost-effective and sustainable alternative to soymeal and fishmeal.

• GLO — glō is a venture-backed company focused on the development and commercialization of advanced LED display products using nanotechnology. The unique nanotechnology is based on 11 years of research at Lund University’s Nanometer Structure Consortium. Headed by Professor Lars Samuelson, one of the world’s leading scientists in this field, who haspublished more than 500 papers related to this technology.glō's first office is in Lund, Sweden, where basic material research continues for the next generation nanotechnology. glō's research and product development along with pilot fabrication operation is carried out at glō-USA in Sunnyvale, California. In 2016, glō established an Asia office in Taipei, Taiwan, one of the largest and fastest-growing regions for LED lighting and display applications.glō's technology sidesteps the technical limitations of current planar LED technology. It allows for the creation of highly efficient, stable and ultimately unique red, green, blue (RGB) emitters out of one material system. It aims to achieve the industry’s best color stability and ultimately enables the growth of red, green and blue emitters on the same wafer. Highly-efficient white LEDs with high color rendering will be possible without the need for phosphor conversion. It is the next enabling technology for advanced display, illumination and automotive applications.glō nanowire light-emitting diodes (nLEDs) are based on its proprietary hetero-structured semiconductor nanowire epitaxial growth and process technologies for which standard manufacturing equipment and materials can be utilized.glō currently holds over 175 patents across US, Europe and Asia. These patents are not subject to any cross-licensing with the LED oligopoly. The glō team is constantly strengthening its intellectual property position in this technology and related applications.
• SantoSolve — SantoSolve is developing topical analgesic products based on non-radioactive strontium as the active substance. The Development program was initiated based on experimental clinical use of strontium-based products showing evidence of strong local analgesic effects on several localized pain conditions of both nociceptive and neuropatic origin. Nosignificant adverse effects associated with the treatment was reported.The company’s lead product, 2PX, is topically administered, utilizing dermal penetration enhancers for delivery of the active agent to its subdermal site of action. Phase I safety and pharmacology studies showed the active agent to have low systemic bioavailability, and only few and minor adverse effects were observed at the site of administration. In open label Phase II clinical trials, the product has shown strong analgesic effect in both nociceptive and neuropatic pain conditions. In follow up, placebo controlled trials, the analgesic effect of the product has been further documented. In the company’s most advanced pain indication under study, osteoarthritis, the company has recently completed the Phase II program.These trials supports the open label results and document statistically that the analgesic effect in patients treated with 2PX is superior to that observed with placebo treatment.
• Sol Voltaics — Founded in 2007, Sol Voltaics AB is a venture-backed, development-stage nanotechnology company focused on development and commercialization of highly efficient, third-generation photovoltaic concentrator solar cells based on its proprietary heterostructured nanowire epitaxial growth and process technologies.
