DC Opportunities is excited to announce the publication of new paper focusing on the development of a Maximum Power Point Tracking (MPPT) system for solar-powered yachts. This was presented earlier this year at the 2024 ICDCM. The system addresses partial shading issues caused by yacht masts and sails, using string-level converters and an isolated converter to maximize energy yield, even in challenging conditions. The research demonstrates a threefold increase in power generation, pushing the boundaries of renewable energy in marine applications.

DC. Een hype of een dingetje?

Datum: 08-10-2019

Tijd: 13:30 – 16:30

Sprekers/Partners: Henry Lootens, Bestuurder Stichting Gelijkspanning Nederland | Maarten de Vries, Programmamanager TKI Urban Energy | Diego Zuidervliet, R&D Engineer ATAG Benelux | Laurens Mackay, Oprichter DC Opportunities R&D | Henri Overbeek, Technisch specialist Venema Technisch Bedrijf

Meer energie distribueren met gelijkspanning
In Nederland ligt al heel veel koper in de grond. Met gelijkspanning kunnen we hier veel beter gebruik van maken dan nu met AC. Laurens legt aan de hand van een onderzoek in Zoetermeer uit dat 5 keer meer energie over dezelfde kabel echt kan.

Vragen die beantwoord worden:
Klopt het dat er met gelijkspanning 5x zoveel energie over dezelfde kabel kan?
De LED straatverlichting in mijn gemeente werkt toch al op gelijkspanning?
Wat kun je nog meer met de stroomkabels die lantaarnpalen van energie voorzien?

On the 4th of April 2019 the European DC Forum took place in Eindhoven, The Netherlands. DC Opportunities R&D was present to discuss with participants the future of DC grids. Dr. Laurens Mackay gave a keynote in the morning.

Early this year, DC Opportunities R&D participated in the 2nd stage regional round of the IEEE “Empower a Billion Lives” competition held in Seville, Spain. This global competition seeks scalable solutions to tackle energy poverty.

Dr. Laurens Mackay and Lukas Irazusta pitched the rural electrification concept that DC Opportunities R&D is currently working on. A field test is scheduled later this year in Ethiopia.

It was a great opportunity to meet people working in this field, and share ideas and points of view.
