Limiting greenhouse gas emissions from land use in Europe

New research presented by IIASA researcher Hannes Bottcher at the EGU General Assembly this week estimates future land use emissions for the European Union, showing that Europe could potentially reduce greenhouse gas emissions from land use by more than 60 percent by 2050.

Diatoms explain release of CO2

Scientists have found unexpectedly high concentrations of opal, a mineral containing silicate, in marine sediments during the transition periods from ice ages to warm phases. The explanation as to what caused these high concentrations can also clarify how oceans release sequestered carbon dioxide. The underlying mechanism is still unexplained today.

Global solar photovoltaic industry is likely now a net energy producer

The rapid growth of the solar power industry over the past decade may have exacerbated the global warming situation it was meant to soothe, simply because most of the energy used to manufacture the millions of solar panels came from burning fossil fuels. That irony, according to Stanford University researchers, is coming to an end.

Hydrogen from methane without CO2 emissions

Production of hydrogen from methane without carbon dioxide emissions is the objective of a project in which KIT is a major partner. At KALLA, the Karlsruhe Liquid-metal Laboratory, researchers are setting up a novel liquid-metal bubble column reactor, in which methane is decomposed into hydrogen and elemental carbon at high temperature.

Study provides new insight into photosynthesis

Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis.

The Combined Power Plant 2 Project: Renewable energy yielding results

A network of small power plants capable of replacing traditional power stations has long been the dream of proponents of renewable energy. The idea, however, has always foundered on concerns over whether a decentralised network could meet national energy demands and provide a stable service while dealing with such huge capacities. Now, a team of European researchers have taken a giant step towards making this dream a reality with the Combined Power Plant 2 (Kombikraftwerk2) project.
