The 100% self-sufficient Boat

The Energy Observer is a 100% energy self-sufficient boat, sailing around the world to prove the usefulness of cutting-edge technologies, including a hydrogen fuel cell made with help from Toyota.

Somewhere in the vast ocean, a little boat covered in solar panels is doing something extraordinary: making its own hydrogen fuel from the seawater underneath it.

Hydrogen has long been touted as a clean-energy alternative to fossil fuels, though it has so far failed to catch on in our daily lives. People don’t want to buy hydrogen cars until there are enough hydrogen refueling stations — and there’s not much incentive to build hydrogen refueling stations until more people are driving hydrogen cars. That’s one thing the Energy Observer team hopes to change.

The Energy Observer uses a patchwork of different cutting-edge technologies to generate enough energy to power nine homes each day. During the day, 200 square meters of solar panels charge up the boat’s lithium ion batteries. Any extra energy is stored as hydrogen, thanks to a special fuel cell that goes by the name Rex H2 (short for Range Extender H2).

The Rex H2 was made by Toyota, using components from Toyota’s hydrogen-powered Mirai vehicle line. The fuel cell brings in seawater, removes the salt and then separates the H from the pure H20 with electricity.

When the Energy Observer began its journey in 2017, it could only produce hydrogen while stopped. That changed in a big way with the addition of the Oceanwings, 12-meter sails that improved the efficiency of the Energy Observer from 18% to 42%, to the point where it can now produce hydrogen even while sailing.

While there is a raging debate between proponents of hydrogen fuel cells — including Toyota — and proponents of lithium ion batteries — like Tesla’s Elon Musk — over which technology is best for powering the post-fossil fuel vehicles of the future, one of the main benefits of hydrogen is its ability to store more more electricity by weight than its lithium ion competition. This benefit is especially useful at sea, where weight capacity is an important consideration.

Because fossil fuels have had more than a century’s head start, we now find ourselves far beyond the point of any one technology being a silver bullet for our growing energy needs. A sustainable future will require a patchwork of new technologies, like the one powering the Energy Observer — and the investment to develop and scale them up for future generations.

Danish Delegation in Iran Eyes Shipping, Energy Deals

The Danish foreign ministry said its minister, Kristian Jensen, travelled to Tehran with a delegation representing 58 companies on Monday and that exports could increase by 500 million Danish crowns ($72 million) once sanctions against Iran’s nuclear programme are lifted.
News agency Shana cited Iranian Petroleum Minister Bijan Zanganeh as saying Danish companies were interested in developing oil fields in the Caspian Sea including the South Pars gas field, which also produces condensates.
Global conglomerate A.P. Moller-Maersk is in the oil industry through its Maersk Oil unit. The company declined to give details of any talks it had with Iranian officials.
The Mehr news agency also cited the Islamic Republic of Iran Shipping Lines (IRISL) as saying that Maersk Line, the world’s largest container shipping company, would begin services to Iranian ports.
“We can confirm that we have met with representatives from the Iranian government to discuss possible projects. Nothing has been agreed and we cannot share further details,” Maersk said in a statement.
Mehr also cited Energy Minister Hamid Chitchian as saying that Denmark offered to invest in the construction of a wind turbine factory.
Denmark’s Vestas, the world’s largest wind turbine maker, said its representatives were present in Tehran and the company was looking into opportunities there but would not elaborate on any talks.
One early Danish mover on Iran was drug maker Novo Nordisk which said in September it would build a $78 million manufacturing plant in the country, signalling what it called a “long-term commitment to Iran”.
The Danish foreign ministry directed questions to its delegation in Iran, which confirmed a memorandum had been signed with Tehran on insuring Danish exports to Iran but declined to comment on other individual business talks.
