A team of scientists at the University of Cambridge has developed a way of using solar power to generate a fuel that is both sustainable and relatively cheap to produce. It’s using natural light to generate hydrogen from biomass.

One of the challenges facing modern society is what it does with its waste products. As natural resources decline in abundance, using waste for energy is becoming more pressing for both governments and business.

A new analysis indicates that the UK’s CO2 output is at a record low, and it’s largely down to one major action: a reduction in coal use.

Switzerland is not fully exploiting a significant source of clean energy: 173,000 tonnes of used wood could be re-used producing valuable heat and power energy today, in addition to the 644,000 tonnes of used wood already being used. This was the conclusion reached by a nationwide survey conducted by the Swiss Federal Research Institute for Forest, Snow and Landscape Research (WSL) among 567 companies in the construction, waste management and transport sectors.

The 2011 Fukushima catastrophe is an ongoing disaster whose end only gets more remote as time passes. The government is desperate to get evacuees back into their homes for the 2020 Tokyo Olympics, but the problems on the ground, and in the breached reactor vessels, are only getting more serious and costly, as unbelievable volumes of radiation contaminate land, air and ocean.

Iran can transition to a fully renewable electricity system and financially benefit from it by 2030. Researchers at Lappeenranta University of Technology (LUT) show that major oil-producing countries in the Middle East and North Africa (MENA) region could turn their abundant renewable energy resources into lucrative business opportunities in less than two decades.

There have been many attempts to modify this stubborn little enzyme. But none have succeeded, until now. With new findings from Chalmers the enzyme FAS has started to produce sustainable chemicals for biofuels.

We are in great need of sustainable and clean alternatives to oil-derived products. One of the choices at hand is to produce chemicals and biofuels from sustainable biomass.

An international team of scientists led by Liang-shi Li at Indiana University has achieved a new milestone in the quest to recycle carbon dioxide in the Earth’s atmosphere into carbon-neutral fuels and others materials.

The chemists have engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide -- a carbon-neutral fuel source -- more efficiently than any other method of "carbon reduction."

That’s a choice drivers could make at the pump one day. But for algal biofuels to compete with petroleum, farming algae has to become less expensive. Toward that goal, Sandia National Laboratories is testing strains of algae for resistance to a host of predators and diseases, and learning to detect when an algae pond is about to crash.

Understanding how the structural and chemical makeup of the material changes during the charge/discharge process could help scientists advance battery design for future energy storage needs

Sometimes understanding how a problem arises in the first place is key to finding its solution. For a team of scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, taking this approach led them to the cause of degraded performance in an operating sodium-ion battery.

A record drop in coal use — coupled with the rapid growth of renewable energy, an expansion of energy efficiency programs, and an increase in burning natural gas for electricity — have driven carbon dioxide emissions in the UK to their lowest levels since the 1920s, according to a new study by the non-profit group, Carbon Brief.
