EcoWave Power


EcoWave is a wave energy company that offers sustainable solutions for harvesting energy. Its technology extracts energy from ocean and sea waves and converts it into electricity, creating more practical and affordable wave energy solutions for world companies. EcoWave Power’s wave energy converter harvests wave energy from both high and low waves, and offers a less expensive price over traditional energy generation methods from coal, oil, or gas or even renewables versions such as wind and solar.


Green Wall


Green Wall-Israel builds vertical walls that can grow plants, flowers, vegetables, herbs, and spices. Its gardens are sustainable, ingenious use of space to add greenery to interior design whether in offices, building structures, walls, or homes. Greenery absorbs carbon dioxide from the air and generates oxygen, improving overall air quality. In addition, its vertical wall provides plants with necessary nutrients for long-term growth, and was created by a team of botanists, architects, and bioengineers. The panels the plants are grown on are also flexible and made of sustainable materials.




Luminescent generates electricity and heat, with high efficiency, storing some heat that is later converted to electricity using its heat engine. Its technology can deliver better greener solutions for solar energy that require high amounts of electricity to produce hydrogen. It simply does so using a more cost-efficient and energy-efficient method. On its team, Luminescent combines experts from academia and the solar industry, including Prof. Carmel Rothschild, who teaches an optical engineering course at the Technion Institute of Technology and Doron Tamir, an experienced solar energy entrepreneur.




Israeli startup H2Pro generates hydrogen and oxygen and cuts down on costs and harmful emissions. While hydrogen is a greener replacement for fossil fuels, whenever it is burned when it converts energy into electricity in fuel cells, it releases water. However, unlike most elements, hydrogen is hardly found “naturally” on Earth, and must be separated from other compounds. While some methods include extracting it from natural gas sources, this method releases harmful carbon emissions. H2Pro E-TAC system generates hydrogen and oxygen in two unique processes that cut down on costs, while reducing harmful vehicle and production emissions.




Foodtech Simpligood produces the world’ most nutrilional form of algae, spirulina, which is filled with several beneficial vitamins and minerals. In a uniquely Israeli twist, Simpliigood harvests fresh spirulina in the arid desert Arava region within specially-equipped greenhouses. Spirulina helps the immune system, is anti-inflammatory, and also helps regulate cholesterol levels. It is also a high protein substitute for meats. Simpliigood uses no pesticides, and its produce absorbs carbon dioxide from the air, is tended with 98% recycled water, and has zero waste byproducts. "What drives me every morning to do what I do at Simpliigood is the idea of leaving the world a better place for my children, and for future generations. We grow spirulina, which is actually the most efficient protein found in nature today, and are essentially turning the sun's rays into a complete protein," Simpliigood CEO Lior Shalev said.

One groundbreaking Israeli technology that will change the way milk is consumed is being carried out by foodtech startup, BioMilk, which aims to create a revolution in the dairy industry. The company is developing an industrial process for producing pasteurized milk from milk cells without milking cows. The milk substitute market generated $50 billion in 2019, while in 2025 that will double and stand at around $98 billion a year. The company, which is headed by CEO Tomer Eisen, enables a more sustainable production of high-value cultured dairy products, while preserving the environment, reducing greenhouse gases, preserving natural resources such as water and land as well as the quality of animal life. The company holds the rights to use intellectual property from the Hebrew University of Jerusalem’s commercial arm headed by Dr. Nurit Argov Argaman, who is also one of the company's founders, director, and chief technology officer. Prof. Maggie Levy, who is also one of the company's founders, also serves as a senior researcher and consultant at BioMilk.

The company detects leaks and saves billions of gallons of water using its technology that processes microwave signals from satellites to detect water leaks for governments and water corporations around the world. The company was founded in 2013 by Lauren Guy, who developed an algorithm that utilizes radars located on satellites, in order to detect suspicious points of water leakage, sewage, drainage faults and water accumulation on the ground. Some 46 billion liters of water are lost per day due to outdated piping systems and poor maintenance. In addition, more than 20% of treated drinking water in Europe and the US is lost in distribution systems. Utilis believes that 75% of it could be regenerated and purified for use. Its technology has been implemented in over 400 projects around the world, in over 55 countries including the U.S., Italy, the UK, Chile, China and South Africa. So far, it has located over 30,000 leaks in more than 25 billion liters of water, reducing electrical usage as well as cutting down on 11,000 tons of CO2 emissions per year.
