Hydrogen Challenger: Sustainable Energy on the High Seas

- Adam Clare

The Hydrogen Challenger is a tanker ship that has gone from 20th century ideas to storing 21st century hydrogen energy.

Hydrogen Challenger

From Wikipedia:
Hydrogen Challenger is a 66 meter (216′ 6″) refitted coastal tanker for mobile hydrogen production, it is fitted with a vertical axis wind turbine that generates electricity for the electrolysis of water to fill the hydrogen storage tanks. The total storage and transportation capacity is 1,194 m³ (42,000 ft3), it is stationed in the German Bight or near Helgoland (where the most wind is) and docks in Bremerhaven where the produced hydrogen is delivered to the market.

Wind Power Shelters Sea Life

- Adam Clare

You read that right: wind power generation can shelter sea life. Offshore wind farms help create spaces that encourage sea life to grow in a similar fashion to coral reefs.

Offshore wind power and wave energy foundations can increase local abundances of fish and crabs. The reef-like constructions also favour for example blue mussels and barnacles. What’s more, it is possible to increase or decrease the abundance of various species by altering the structural design of foundation. This was shown by Dan Wilhelmsson of the Department of Zoology, Stockholm University, in a recently published dissertation.

“Hard surfaces are often hard currency in the ocean, and these foundations can function as artificial reefs. Rock boulders are often placed around the structures to prevent erosion (scouring) around these, and this strengthens the reef function,” says Dan Wilhelmsson.
