‘Técnico Solar Boat’ - Driven by a passion for sustainable engineering ‘Técnico Solar Boat’ is a university project which consists of engineering students from the Instituto Superior Técnico, Portugal. They work together on the development of a manned competition vessel having now produced three prototypes powered exclusively by solar energy and most recently by hydrogen. The team’s latest solar prototype revealed in June 2021, the SR03, is stronger, lighter, more efficient than previous ones and features a new foiling system, with foils and struts being built in carbon fibre instead of aluminium. SR03 has a dual motor system, with 10kW and 5kW, for high and low power respectively, able to propel the boat to speeds of up to 20 knots. This summer, they also revealed their first hydrogen powered boat, São Miguel (SM) 01.

also the hydrofoils and struts on SR03 as well as technical support, with pleasing results. “We loved working with your products and have achieved great results in our prepreg parts. We couldn’t have done this without Gurit’s support! We are looking forward to the future and continuing to work with Gurit products”. said Maria Portijo, Design and Composites Technical Director for the team. Over the summer, the team travelled to Madeira for “Odisseia 2021” a series of crossings, to put the SR03 through its paces and showcase all the improvements made to this latest prototype.
The SR03’s foil, made from Gurit SE 84LV carbon prepreg Gurit sponsored the team with its SE 84LV carbon prepreg, typically used for high performance, lightweight marine structures, alongside SA 80 toughened adhesive film, which was used to build the hull, deck, internal structure and
Making sustainable technology available Although the team participates in worldwide engineering competitions, they feel that their main responsibility is to promote renewable energies, sustainability and electric mobility. In order to help push this sustainable technology forward, the team have adopted an ‘open source’ ethos, whereby they share all of their information on their builds online, including source code and 3D models.

Lasting confidence in Gurit prepregs at Carrington Boats Jason Carrington, founder of Carrington Boats Ltd, is a long-time proponent of Gurit prepregs. “As an apprentice I remember the first SP (Gurit) prepreg boat built at Green Marine, the IOR 50-footer “Promotion”. This was in the 80’s; some 40 years later we still predominantly use Gurit prepregs here at Carrington Boats. There is no doubt that composite boat building, particularly lightweight race boats is a tricky business. Having 100% confidence and familiarity with your materials is absolutely vital. Over the years we have also built up a strong relationship, indeed a friendship, with both the technical and sales teams. Currently we have 3 boats in production, 2 using Gurit’s longstanding SE 84 and 1 using Gurit’s new low temp prepreg and SPRINT™ systems.”

Marine trade shows return in 2021 Gurit thanks all those who visited us at IBEX in Tampa, Florida in September and at METSTrade in Amsterdam in November to meet with our team members and learn about our offerings for the marine industry. IBEX celebrated its 30th year with nearly 100 new exhibitors, and provided an opportunity for us to discuss sustainable solutions for boatbuilding, including Kerdyn™ Green recycled PET. At METSTrade, visitors had the opportunity to see examples of Gurit’s new SE 75 prepreg line, which builds on the heritage and performance of our SE 84 materials and saves time with more versatile curing possibilities. We are grateful for all who attended and made these shows successful for everyone in the industry.

Hydrogen is fuelling the future of marine a considerable impact on the reduction of consumption of fossil fuels across the event. Technical details have yet to be released but it is thought that the boats will store compressed hydrogen gas at 350 bar in light weight composite tanks. The hydrogen gas is then supplied to the fuel cells which, when mixed with oxygen, produce the electricity required for the boat’s propulsion and operation.
Hydrogen is a promising technology to instantaneously harness and store the power generated by renewable energy. And hydrogen is certainly something to keep our eye on in the marine sector too. Five years ago it would have been considered a fringe idea, but the adoption of hydrogen is now being driven from the top-down, with many countries discussing it at policy-making levels. And forward-thinking marine companies are taking on the challenge, developing innovative solutions to incorporate hydrogen-fueled propulsion and operational systems.
“Emirates Team New Zealand continues to be at the forefront of innovation and we intend to really drive the development curve of new and clean technology in the marine industry. It is our hope that we can make a seismic shift into hydrogen power and an emission free statement for the industry.” Grant Dalton, Emirates Team New Zealand CEO
A sailing team goes hydrogen Emirates Team New Zealand, to whom Gurit has been a long-standing supplier, recently revealed its sleeklined hydrogen-powered foiling chase boat design. Once launched and verified, and with the support of the Challenger of Record INEOS Team UK, the Protocol for the 37th America’s Cup contains a provision that all teams must use hydrogen powered support boats.

AQUON One setting the pace for sustainable yachting
Another example of more environmentally friendly solutions for yachting is AQUON One, a truly sustainable yacht in the form of an ocean-going electric catamaran that will be fully self-sufficient energy-wise. The 19.5m luxury yacht captures energy aboard with 64m2 of solar panels, directing it into either short or long-term storage. Short term, the energy is stored in lithium-ion batteries that deliver power on demand to the yacht’s propulsion and other systems. Long term, any excess energy captured by the solar panels is used to power an onboard electrolyser which converts sea water to ‘green’ hydrogen (that is, hydrogen generated from renewable sources). The hydrogen gas is compressed to 300 bar and stored in lightweight carbon tanks until it is needed, when fuel cells it convert back into electricity to be used by the propulsion and onboard systems.
The only biproduct of this process is water and heat, which is used to generate hot water onboard. As a result, the yacht can be fully self-sufficient in terms of energy, cruising noiselessly and emission-free for days without needing to ‘plug-in’ to shore. It’s exciting to see this cutting-edge green energy technology being developed for and within the marine industry and understand how green hydrogen could become the energy of the future for us all. AQUON One features further sustainable innovations and its design has been inspired by nature, the highly efficient shaped manta. A truly fascinating project!
The manta ray moves elegantly and in silence through the ocean. It was nature’s inspiration for the AQUON One designers.
