High-entropy oxide as high-activity electrocatalyst for water oxidation

Green Car Congress

Researchers from the University of Twente in The Netherlands have developed a new high-entropy perovskite oxide (HEO) as a high-activity electrocatalyst for the oxygen evolution reaction (OER)—the key kinetically limiting half-reaction in several electrochemical energy conversion technologies, including green hydrogen generation.

EU research project IDEALFUEL seeks to develop marine low-sulfur heavy fuel oils from biomass; Bio-HFO

Green Car Congress

However, HFOs are banned in the national waters of many countries. In addition, the International Maritime Organization (IMO) is seeking to ban HFO use in Arctic waters. IDEALFUEL is coordinated by Eindhoven University of Technology and involves participants from four countries. The participants are Vertoro B.V. (NL);

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

Business-as-usual’ projections of future conversion rates, based on historical rates over the past two decades, indicate that 6–9 Mha of peatland in insular Southeast Asia may be converted to plantations by the year 2020, unless land use planning policies or markets for products change. —Miettinen et al.

Study suggests energy and GHG impacts of synthetic hydrocarbon fuels from CO2 are greater than impacts of existing hydrocarbon fuels

Green Car Congress

Researchers at the Institute of Environmental Sciences at Leiden University, The Netherlands) have concluded that the energy demand and climate impacts of using CO 2 to produce synthetic hydrocarbon fuels by using existing technologies can be greater than the impacts of existing hydrocarbon fuels.

Researchers confirm existence of North Icelandic Jet current; implications for ocean response to climate change

Green Car Congress

As part of the planet’s reciprocal relationship between ocean circulation and climate, the AMOC transports warm surface water to high latitudes where the water warms the air, then cools, sinks and returns toward the equator as a deep flow. ” We present the first comprehensive measurements of the NIJ.

Dutch Researchers Developing Catalytic System for Producing Hydrogen from Gas-Fired Power Stations

Green Car Congress

More H 2 can form via the water–gas shift reaction if CO is present. Researchers at the University of Amsterdam in the Netherlands are developing ceria-based catalysts as candidates for integrating methane combustion and hydrogen generation in power plants. Methane conversion and hydrogen yield at 550 °C.

Study finds GHG emissions associated with palm oil production have been significantly underestimated; implications for carbon intensity of biofuels as well as biofuel policies in Europe

Green Car Congress

A new study on greenhouse gas (GHG) emissions associated with the conversion and degradation of peatland in palm oil plantations in Southeast Asia has determined that past studies have generally significantly underestimated emissions associated with palm oil grown on peatland.
