Since commercial ships are responsible for much of the world’s carbon emissions, and as 15 of the biggest ships alone emit more of NOx and SOx than all the world’s cars put together (The Economist), the industry has been singled out for its harmful role in the global climate change crisis.
Traditionally, shipping companies have relied on heavy fuel oil, which is the most commonly used and can propel ships very efficiently but is highly polluting. As a result of increasing global awareness and new international regulations on greenhouse emissions, the shipping industry is now rushing to find environmentally friendly solutions that will enable them to comply with existing and future regulations.
So far, alternative fuels intended to replace heavy fuel oil have proven to be problematic: although they do reduce greenhouse emissions, they are up to four times more expensive than conventional fuel. In order to ensure a minimal profit margin, shippers will have to use these new fuels divert the extra cost to their customers and it is then reflected in excessively expensive imported goods.
Successful Proof of Concept
The solution developed by Israeli startup NayamWings, doesn’t only significantly reduce carbon emissions, it is also enables shippers to lower their costs significantly by up to 25%. In fact, the Return on Investment (ROI) for ships that install the NayamWings technology is a mere 2-4 years. Faster than any other option in the market.
NayamWings’ solution consists of a hybrid wind propulsion system using rigid wings (more similar to an airplane wing) that are autonomously controlled and easy to operate.
The wings system propels the ship hybrid with the main engine, making it possible to reduce engine thrust load and save fuel. The system itself is “green” and consumes very low energy. The number of wings required on a given ship depends on its size and other properties, but generally ranges between two and six wings.
The wings can be levelled when sailing under bridges, entering harbors, loading, or unloading, and when sailing in extreme weather conditions.
The company has already completed two very successful proofs of concept (POCs). The first was an 8-meter wing installed on a catamaran. The second POC tested the autonomous management system on a small-scale ship model. The company is now testing a 10-meter wing on a 15-meter yacht, followed by a full-size wing on a large commercial ship in 2023, and enter global markets by early 2024.
The majority of commodities and goods traded around the world are being transport by 90% of all commercial ships that most are suitable for Nayamwings’ solution.
The company expects to capture at least 15% of the new ship market by 2030 – although the potential is much larger than that. .
Shipping companies are already expressing interest in NayamWings’ solution, eager to find a way to comply with the strict new environmental regulations while avoiding the extreme costs of most renewable energy solutions.
Moreover, since shipping companies face quotas on the amount of carbon dioxide emissions they produce, known as ‘carbon permits,’ if they lower their carbon footprint, they can sell their extra carbon permits. A 100,000-ton tanker sailing at a speed of 14 knots, for example, emits around 134 tons of CO2 every day. By installing NayamWing’s technology, the tanker can reduce its fuel usage by up to 25%, thereby reducing its polluting emissions accordingly. This translates to annual savings of around $700,000 from carbon permits, in addition to saving approximately $2 million on fuel costs!
Company and founding team
NayamWings was founded in 2020 by a group of engineers and maritime experts from various backgrounds. Amnon Asscher ,Founder & CTO, is an experienced aeronautical engineer. Saar Carmeli , Co-Founder &CEO, is a former Captain in the Israeli Navy. Avishay Parker, Co-Founder &COO, was also a Navy Commander with a distinguished background in planning and finance.
The company’s advisory board includes leading experts such as Yedidya Yaari, who was the commander of the Israeli Navy and the CEO of Rafael Advanced Defense Systems, and Prof.. Orestis Schinas, the founding partner of HHX.BLUE and an expert in ship financing and maritime transport green solutions.
Since its establishment, NayamWings has been funded by the Israeli Ministry of Energy and has now opened its seed round of $4.5M.
In the past year, the company has been supported by hiCenter’s IN-VENTech Startup Business Program which is funded by the Haifa Municipality with a goal to develop and promote the technological ecosystem of the city.
Hicenter has recently launched in Haifa, the Israeli National Center for Blue Economy. The center’s goal is to lead Israel’s technological entrepreneurial ecosystem in the field of Blue Economy and maritime innovation.
The center will lean on all research institutes, academia, infrastructure, logistics, military industry, nature preservation and innovation organizations that are active in Haifa and its marine space proximity.
“IN-VENTech has provided us the unique opportunity for long lasting support that has proven to be vital to our success” said Amnon Asher.
