Off-grid living comes a step closer
It’s all about energy efficiency
If you compare electric and jet-fuelled flight, around fifty times as much energy goes into a kilo of aviation fluid than into a battery. This means that the combination of long-haul flight and large numbers of passengers won’t work for electric flights for the time being. So, what is preventing all the alternatives for saving on fuel or reducing carbon emissions? It’s actually all down to energy efficiency. On this, the applications and energy carriers show significant variations. Currently, only 30% of fuel is completely used. In existing networks, as much as 40% of energy for heating is wasted because of poor insulation. Hydrogen has 85% energy efficiency. In other words, you’re dealing with multiple variables: weight, use of space, insulation, energy production and conservation, noise reduction, and the most efficient use of hydroelectric, wind and heat sources. Then there’s the fact that all of the materials must be as recyclable as possible.
Off-grid living on the H20
New Electric Marine is working on Dick Gilles’ self-sufficient sailing ship H2O. Everything is designed for comfortable living and sailing with a minimum possible footprint, without having to rely on existing networks or onshore connections. At the shipyard in Middenmeer, the Netherlands, the very latest innovations in energy generation, use and storage are being applied and combined. The results include hybrid propulsion and a large pack of lithium batteries that charge in 2 to 3 hours for 2 to 3 weeks of power supply. The solar panels have been developed in-house, ensuring exceptionally high efficiency on a small surface, while also having the practical advantage that you can walk on them. Repairing or replacing something at sea is never easy, so it helps if the panels can take a beating. We now estimate its lifespan to be 25 years. All in all, the H2O is a strong and robust vessel. Featuring hybrid propulsion, it’s built to navigate the world’s oceans safely.
The capacity of the technologies applied – in terms of energy efficiency and increased power – changes on a daily basis. At New Electric Marine, we offer value-for-money bespoke solutions for all types of electric or hybrid marine applications.
