Electric tugs bring environmental and opex benefits
Crowley has ordered the first all-electric tug in the Americas and Navtek provides data from two years of operating Gisas Power Tug operators are increasingly investing in new tugs with low or zero-emissions propulsion. The transition is being driven by upcoming green legislation, public opinion, and…
A green ‘sea change’ as water transport makes its move
All aboard! Europe’s ferry industry has set sail for an emissions-free future. It’s leading the eco-friendly revolution with electric and hydrogen-powered boats that are destined to make urban transport more sustainable. In just a few months’ time, passengers in Stavanger, Norway, will be able to…

Ammonia in Aquatic Systems
by Ruth Francis-Floyd, Craig Watson, Denise Petty, and Deborah B. Pouder Of all the water quality parameters that affect fish, ammonia is the most important after oxygen, especially in intensive systems, says Ruth Francis-Floyd, Craig Watson, Denise Petty, and Deborah B. Pouder, University of Florida…
Ammonia pollution damaging more than 60% of UK land – report
Study finds most sensitive plant and wildlife habitats are worst affected, yet government has no clear plans to monitor impact Ammonia and nitrogen pollution, mostly from farms, is harming more than 60% of the UK’s land area and hitting the most sensitive habitats for plants…
Ecological Effects of Ammonia
Even at extremely low concentrations aquatic life will be harmed by ammonia. Ammonia occurs naturally in the environment. A small amount of ammonia is generated when lightning strikes and reaches earth in rainfall. But most ammonia is produced by bacteria in water and soil as…
It’s Official. We Can Now Harvest Usable Lithium From Seawater
Without lithium, the all-electric boats of today wouldn’t be feasible, and with an increasing demand for EBs expected to exhaust reserves on water by 2080, this might become inevitable. But there is another way to extract the vital element, or rather another place. The oceans…
Zero-emission Ferries for Zero-emission Islands
Approximately 2.1 billion people use ferries every year, putting the industry on a par with commercial airlines in terms of annual users worldwide. To many cities and their citizens, travelling the waterways lies at the heart of everyday life. While some cities have mandated the…
Study provides first statistical characterisation of methane ultra-emitters from oil and gas
For the first time ever on a global scale, using satellite imagery, scientists have quantified volumes of massive methane emissions due to fossil-fuel extraction activities and their impact on the climate. Their findings partly explain why official inventories generally underestimate the volume of these emissions….
