The Canadian government has just floated the idea for creating new hybrid diesel, hydrogen fuel cell coast guard ships. Three retrofitted fisheries ships would replace four older coast guard ships to patrol both Atlantic and Pacific Oceans off the Canadian coast.
Diesel-powered ships are fairly efficient when they are at full speed and out to sea. But, once they come near shore and are running at half-power they are much less efficient and become more polluting vehicles. This is where hydrogen fuel cells step in.
When the coast guard vessels are in port or around shore near sensitive wildlife areas, the non-polluting hydrogen fuel cells would be used for power. When the same ships head out to sea and use full power then the diesel engines would kick in.
Now, I’ve talked about hydrogen ships many times before. And going hybrid seems like a sensible approach in many situations especially when it comes to protecting our ports and sensitive coastal regions against marine pollution. Let’s hope that the momentum of retrofitting ships with hydrogen fuel cells continues worldwide and doesn’t slow down any time soon.
Hi, we would like to place a guest post at your blog on any subject that you need, for example “Top 10 most powerful cars of 2012” or “The most powerful motorcycles of all times” etc. At this post we would like to place a website link, the subject of the website is salvage cars from American auto auction.
Sorry, no, I write 99-percent of the posts myself. And when there is a guest post, it’s by invitation only. I only ask hydrogen authorities and insiders for guest posts.
