The Power Of Wind: Interview With Bound4blue Founder
Shipowners and operators may be able to decrease their fuel-related costs and pollutant emissions up to 30%, thanks to a new system created by Bound4blue. The Spanish company aims at delivering automated wind-assisted propulsion systems (also called wingsails) that can be integrated onto a wide range of vessels. The Beam spoke with one of the founders, José Miguel Bermúdez.
Who are the people behind Bound4blue?
The project was founded by Cristina Aleixendri, David Ferrer, and me, José Miguel Bermúdez. The three of us are aeronautical engineers, which clearly served as the foundation of the technology developed. We found soft sails installed in sailing boats or yachts, but none in commercial vessels. We believed we could apply our knowledge in aeronautics to build a high-lift device for the shipping industry adapted to its requirements, that could be the solution to the two showstopper challenges they are facing: high fuel operating expenses and emissions reduction pressure from international entities.
We have been selected as one of Europe’s most promising innovators under 35 by MIT and featured amongst the 30 brightest industry European entrepreneurs under the age of 30 by Forbes. The design, manufacture, and launch of scientific capsules to the space, the construction of efficient wind towers, or the deployment of Geodetic Quality Sea-Ice drift buoys in the Arctic are some examples that precede our team and that mark a business and technological trajectory for Bound4blue.
The team is nowadays formed by 15 people, who combine several expertise in different fields of business and engineering, including aerospace engineering, naval architects, electronics engineering, statisticians and mechanical engineering.
How exactly do the automated wind assisted propulsion systems work? Can we talk about renewable energy in this case?
Bound4blue’s wingsail system generates effective thrust from wind power and thereby reduces the engine power required, saving fuel and pollutant emissions. For example, one of the latest cases we are working on is a Handysize (183-meter length) vessel, operating in the route Busan (South Korea) – Seattle (US). In this case, installing two 30-meter units of our system, we can save more than 940 tons of fuel per year, which represents more than 2,900 tons of CO2 savings per year, with an investment payback period of less than three years. Having successfully passed all the tests in the prototyping phase and being within the pilot phase, our systems are now being implemented on four ships.
So to sum up, of course we can talk about renewable energy in this case. The only source we are using in the overall process is the wind power, which is directly used to propel the ships with no intermediate energy conversion. In the end and from a conceptual point of view, it is the same process that humanity has been using for thousands of years, using the wind to navigate.

What makes this technology innovative?
Bound4blue’s innovative technology is a creative application of an already existing one. Wind was once used centuries ago to propel vessels, so it is as simple as going back to the basics but using 21st century aeronautical technology. The solution was inside the industry from the very beginning, but we were able to take our aeronautical knowledge and build it on top of an ancient concept to create Bound4blue’s solution. The challenge we had to deal with was adapting this technology to commercial vessels and finding solutions to problems that are specific to those vessels.
Our technology is capable of providing double-digit fuel savings and emissions reduction with a payback below five years, it can be folded (useful for fleets with air-draft or operations limitations), it has extended operability thanks to the rotation capability and it works with a simple and fully autonomous operation, so no extra training or workload from the crew is required.
What can its impact on the shipping sector be? How can it help reduce emissions in the long term?
Maritime transport is a key industry for our society, transporting over 80% of the worldwide cargo. However, its pollutant emissions are a major environmental challenge. Maritime transport accounts for 3% of the global CO2 emissions, 15% of NO worldwide emissions and 13% of SO2 global emissions; it is having a direct impact on our planet in forms of global warming or acid rain, and being responsible of 14 million cases of childhood asthma each year and 60,000 cardiopulmonary and lung cancer deaths annually. In fact, maritime transport generates as much CO2 as the sixth most polluting country in the world, and the 16 largest vessels in the world generate the same amount of Sulphur emissions as the entire global fleet of cars.
Our technology reduces the emissions produced in the maritime transport of cargo and people by decreasing the use of fossil fuel with the same level of energy used by the ship. According to the Impact Forecast Analysis we carried out using the Climate Impact Forecast tool, more than 590 thousand tons of CO2 emissions will be saved in the following five years due to Bound4blue’s forecasted installations. So our technology will be a massive emission saver in the upcoming years. Also, our solution provides huge opportunities to modernize the infrastructure which will create new jobs and promote greater prosperity across the globe.
What kind of setbacks have you encountered, and what kind of support helped you get through? Where will future endeavors bring you?
As with any product development, there is a risk of obtaining lower performances and not achieving the desired economic viability for the market. The technological and practical feasibility have been proven so far by our land prototypes and the demo is being run for merchant and fishing vessels.
Bound4blue’s solution is highly capital intensive, but we have already succeeded in raising over €5.8 million contribution from private investors and grants. In this type of venture, there is always a risk of slow market acceptance and adoption, but interest in the product has already been proven. Bound4blue has received funding from the European Regional Development Fund throughout several projects granted by the Government of Catalonia and the Government of Cantabria, as well as from the European Maritime and Fisheries Fund (EMFF) throughout two projects which are being developed right now together with other European companies. Moreover, Bound4blue received funding from EIT Climate KIC and presently financial support throughout the extraordinary COVID-19 venture support call. EIT Climate KIC has supported us with financing, mentoring, training and access to a global network of investors, as well as increasing our media exposure. They have helped us translate our business model into more transactions with customers that are validating our core value proposition, as well as enabled us to attract more capital to progress into the next stage in the business development.
Bound4blue is now at a pre-commercial stage. The next step is to implement a worldwide industrial network (shipyards, systems manufacturing and assembly), as well as to grow the team in the business development and commercial departments to expand operations and boost sales in Europe and Asia. Moreover, we will undergo incremental development to decrease costs while increasing efficiency and security.

Renewables and nuclear provided 40.9% of the world’s power generation in 2024, passing the 40% mark for the first time since the 1940s, according to a new global energy think tank Ember report.
Renewables added a record 858 TWh in 2024, 49% more than the previous high in 2022. Solar was the largest contributor for the third year running, adding 474 TWh to reach a share of 6.9%. Solar was the fastest-growing power source (+29%) for the 20th year in a row.
Solar has doubled in just three years, providing more than 2,000 TWh of electricity in 2024. Wind generation also grew to 8.1% of global electricity, while hydro – the single largest renewable source – remained steady at 14% of global electricity.
“Solar power has become the engine of the global energy transition,” said Phil MacDonald, Ember’s managing director. “Paired with battery storage, solar is set to be an unstoppable force. As the fastest-growing and largest source of new electricity, it is critical in meeting the world’s ever-increasing demand for electricity.”
Ember’s sixth annual Global Electricity Review, published today, provides the first comprehensive overview of the global power system in 2024 based on country-level data. It’s published alongside the world’s first open dataset on electricity generation in 2024, covering 88 countries that account for 93% of global electricity demand, as well as historical data for 215 countries.
What drove the rising power demand
The analysis finds that fossil fuels also saw a small 1.4% increase in 2024 due to surging electricity demand, pushing global power sector emissions up 1.6% to an all-time high.
Heatwaves were the main driver of the rise in fossil generation, accounting for almost a fifth (+0.7%) of the increase in global electricity demand in 2024 (+4.0%), mainly through additional use of cooling. Without these temperature effects, fossil fuel generation would have risen by only 0.2%, as clean electricity generation met 96% of the demand growth not caused by hotter temperatures.
“Amid the noise, it’s essential to focus on the real signal,” continued MacDonald. “Hotter weather drove the fossil generation increase in 2024, but we’re very unlikely to see a similar jump in 2025.”
Aside from weather effects, the increasing use of electricity for AI, data centers, EVs, and heat pumps is already contributing to global demand growth. Combined, the growing use of these technologies accounted for a 0.7% increase in global electricity demand in 2024, double what they contributed five years ago.
Clean power will grow faster than demand
Ember’s report shows that clean generation growth is set to outpace faster-rising demand in the coming years, marking the start of a permanent decline in fossil fuel generation. The current expected growth in clean generation would be sufficient to meet a demand increase of 4.1% per year to 2030, which is above expectations for demand growth.
“The world is watching how technologies like AI and EVs will drive electricity demand,” said MacDonald. “It’s clear that booming solar and wind are comfortably set to deliver, and those expecting fossil fuel generation to keep rising will be disappointed.”
Beyond emerging technologies, the growth trajectories of the world’s largest emerging economies will play a crucial role in defining the global outlook. More than half of the increase in solar generation in 2024 was in China, with its clean generation growth meeting 81% of its demand increase in 2024. India’s solar capacity additions in 2024 doubled compared to 2023. These two countries are at the forefront of the drive to clean power and will help tip the balance toward a decline in fossil generation at a global level.
Professor Xunpeng Shi, president of the International Society for Energy Transition Studies (ISETS), said: “The future of the global power system is being shaped in Asia, with China and India at the heart of the energy transition. Their increasing reliance on renewables to power demand growth marks a shift that will redefine the global power sector and accelerate the decline of fossil fuels.”

The next-gen LEAF is almost here, and it’s looking better than ever. This isn’t the electric hatch you are used to seeing. Nissan’s new LEAF EV has more range, a fresh crossover design, and yes, it can finally charge up at Tesla Superchargers with an NACS port. With the official reveal just around the corner, someone already spotted the new LEAF at a Tesla charger in Canada.
Nissan is launching the new LEAF in the US and Canada
A little over a week ago, we finally got our first look at the third-generation LEAF. Nissan’s iconic electric hatch has grown into a “sleek and spacious family-friendly crossover.”
The US and Canada will be the first to see the reimagined LEAF later this year. It will join the Ariya in Nissan’s North American EV lineup as it looks to spark growth in one of its most important markets.
Based on the CMF-EV platform, the same one underpinning the Ariya, Nissan promises the new LEAF will have “significant range improvements.” Although no other details were revealed, Nissan’s vehicle programs chief, Francois Bailly, told TopGear.com that it’s expected to have WLTP driving range of up to 373 miles (600 km).
It will likely be lower on the EPA scale, but anything even close to 300 miles would be a major improvement over the current 212 EPA-estimated miles offered on the 2025 LEAF SV Plus.
The next-gen LEAF will also be Nissan’s first EV to feature an integrated NACS charging port. With its official debut later this year, the new model is out for testing and was just caught testing at a Tesla Supercharger in Canada.
If you didn’t know what vehicle it is, the LEAF is hardly recognizable. The new image from KindelAuto gives us a closer look at the new crossover design. It almost looks like a Tesla sitting in front of the charger.
The new LEAF is one of 10 new and refreshed Nissan vehicles set to launch in the US and Canada. It will arrive later this year, followed by the fourth-gen Rogue in 2026, which will be available as a PHEV for the first time.
Nissan also plans to build a new “adventure-focused SUV” at its Canton, Mississippi, plant in late 2027. The teaser shows what appears to be a rugged electric Xterra. We’ll have to wait for more details on that one.
Nissan will reveal additional info about the upcoming LEAF mid-year. Check back soon for more updates.

The Port of Barcelona launched the Ecocat Tres, a highly efficient, all-electric commuter ferry powered by Molabo’s ARIES i50 electric motors.
Ecocat Tres is the latest zero-emission ferry in Bus Nàutic’s growing electric fleet, providing clean transportation between the Drassanes and Llevant wharves. In just its first three months, the Bus Nàutic service logged over 125,000 sustainable trips. Operated by ALSA and backed by the Port of Barcelona, the initiative offers locals and visitors an eco-friendly way to travel, cutting down on road congestion and air pollution in the bustling city.
Built by Spanish shipbuilder Metaltec Naval, Ecocat Tres is a 15-meter aluminum catamaran that carries up to 84 passengers. It even includes a rooftop deck, offering extra seating and a breezy ride across the port. The ferry runs every 15 to 30 minutes for at least 12 hours each day, with the entire trip taking about 10 minutes.
Under the deck are two powerful 48V Molabo ARIES i50 motors, enabling the electric ferry to hit a top speed of 12 knots. Cruising at its regular operational speed of 5 knots, Ecocat Tres can run efficiently for up to 21 hours on a single charge, making it highly reliable for daily commuters.
Molabo’s motors have a low-voltage setup, which makes them safer to maintain compared to traditional high-voltage electric systems. Passengers also enjoy a smoother, quieter ride thanks to significantly reduced noise and vibrations onboard. Azimut Marine supplied the full propulsion and energy system, which includes two ARIES 50 kW electric drives, 36 batteries providing a total of 216 kWh, fast chargers, and integrated solar panels. Impressively, solar power alone can cover up to 40% of the ferry’s energy needs.
Ecocat Tres will cut around 90 tons of CO2 emissions each year, making a positive impact on Barcelona’s ambitious climate goals.
Port of Barcelona president José Antonio Carbonell said, “This 100% electric, zero-emission passenger ferry is helping us reshape mobility in the port and accelerate the decarbonization of our operations.”
