Another innovative feature has been added to the world's first practical 'artificial leaf', making the device even more suitable for providing people in developing countries and remote areas with electricity, scientists reported here today. It gives the leaf the ability to self-heal damage that occurs during production of energy.
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.
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.
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 U.S. Department of Energy (DOE) has announced a five-year renewal of funding for the Joint BioEnergy Institute (JBEI), a Bay Area multi-institutional scientific partnership. Under the renewal, JBEI will be funded at the rate of $25 million annually through 2018.
Despite more energy-efficient manufacturing, researchers found that such processes may be approaching their thermodynamic limits: There are increasingly limited options available to make them significantly more efficient. The result is that energy efficiency for many important processes in manufacturing is approaching a plateau.
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.
A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world.
McGill University Biology Professor Catherine Potvin, a renowned expert on climate change and tropical-forest ecology, will begin sharing insights from her laboratory|s research through a novel series of videos to be made available online starting this week.
Accounting for some 40% of all energy consumption, the building sector is one of Europe's most energy consuming. And as the vast majority of this power comes from fossil fuels, increasing energy efficiency, reducing CO2 emissions and using Renewable Energy Sources (RES) has in recent years become priority.
The continued maintenance of fossil fuel subsidies is a global scandal and governments should work to transform these subsidies into financing for energy efficiency and renewable energy, says WWF, responding to a report released last week by the International Monetary Fund (IMF).
Joseph Miceli, a researcher at ASU's Biodesign Institute, studies specialized microorganisms known as anode respiring bacteria (ARB). Rather than investigating their role in health and disease however, his research explores the ability of these microbes to clean up waste and produce useful energy in the form of electricity or hydrogen.
