Damen delivers hybrid tugboat to Royal Netherlands Navy; up to 30% lower fuel consumption, 40% fewer emissions

Green Car Congress

International shipyard group Damen recently delivered the first of a series of three hybrid tugboats (ASD TUGs 2810 Hybrid) to the Royal Netherlands Navy (RNLN). The two additional Swedish tugs are also of a standard design, but designed for operations in icy waters. The MTU brand is part of Rolls-Royce Power Systems.

Wärtsilä and partners developing emissions-free barge concept

Green Car Congress

The concept is supported by the Dutch Ministry of Infrastructure and Water Management. Within the Netherlands transport sector, inland navigation accounts for 5% of carbon dioxide emissions. With the help of a 2000 kWh Repack container, an inland vessel can sail for two to four hours.

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

Projected changes in summer mean usable capacity of power plants in the US and Europe for the SRES A2 emissions scenario for the 2040s (2031–2060) relative to the control period (1971–2000). Compared to other water use sectors (e.g. Source: van Vliet et al. Click to enlarge. 19% in Europe and 4.4—16%

Greenland Ice Cap Melting Faster Than Ever

Green Car Congress

Collaborating on the paper were scientists from Utrecht University, the Netherlands Royal Meteorological Institute, Delft University of Technology, Bristol University (UK) and the Jet Propulsion Laboratory (USA). The Greenland ice sheet contains enough water to cause a global sea level rise of seven metres.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Historical analysis shows strong acceleration of plantation development in recent years: 70% of all industrial plantations have been established since 2000 and only 4% of the current plantation area existed in 1990. Tropical peatlands cover more than 25 Mha in Southeast Asia and are estimated to contain around 70 Gt of carbon.

Analysis of drill cores links variations in CO2 40M years ago to changes in global temperatures; questions as to the source of CO2

Green Car Congress

The study was led by scientists at Utrecht University, working with colleagues at the NIOZ Royal Netherlands Institute for Sea Research and the University of Southampton. Algae use photosynthesis to harvest the energy of the sun, converting carbon dioxide and water into the organic molecules required for growth.
