Top nitrogen researchers imagine world beyond fossil fuels
25 May 2018 at 10:43am
At the invitation of the U.S. Department of Energy's Office of Basic Energy Sciences, 17 top experts in nitrogen research gathered to discuss nitrogen activation chemistry and the field's future.
How greener grids can stay lit
24 May 2018 at 11:15am
Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.
Don't wait for a unicorn: Investing in low-carbon tech now will save money
21 May 2018 at 10:17am
Waiting for a 'unicorn technology' that provides green energy at low cost could be more expensive than adopting low-carbon energy technologies now.
Advanced biofuels can be produced extremely efficiently, confirms industrial ...
21 May 2018 at 10:11am
Researchers have developed new technologies that can be used to convert industrial plants to produce fossil-free heat, electricity, fuel, chemicals and materials. The technical potential is enormous -- using only Sweden's currently existing power plants, renewable fuels equivalent to 10 percent of the world's aviation fuel could be produced.
New catalyst upgrades greenhouse gas into renewable hydrocarbons
17 May 2018 at 11:36am
Engineers have designed a most efficient and stable process for converting climate-warming carbon dioxide into a key chemical building block for plastics -- all powered using renewable electricity.
Can we get 100 percent of our energy from renewable sources?
17 May 2018 at 8:38am
Some researchers doubted the feasibility of many of the recent scenarios for high shares of renewable energy. Now scientists have hit back with their response to the points raised. They demonstrate that there are no roadblocks on the way to a 100 percent renewable future.
European wind energy generation potential in a 1.5 degree C warmer world
16 May 2018 at 7:14pm
The UK and large parts of northern Europe could become windier if global temperatures reach 1.5 degrees C above pre-industrial levels, according to a new study.
A green approach to making ammonia could help feed the world
15 May 2018 at 10:15am
Researchers have developed a new 'green' approach to making ammonia that may help make feeding the rising world population more sustainable.
Carbon-recycling system: Two-electron chemical reactions using light energy, ...
15 May 2018 at 7:57am
Scientists are one step closer to building a carbon-recycling system that can harvest solar energy to efficiently convert CO2 and water into liquid fuels. By optimizing many parts of the system, the researchers say, they can now drive two-electron chemical reactions, a substantial advance over one-electron reactions, which are energy inefficient.
Vulnerable communities may be adversely affected by the transition to cleaner...
7 May 2018 at 12:31pm
Researchers have developed a method for identifying communities that may be negatively affected by clean energy policies that hasten the move from fossil fuels to more environmentally friendly solutions.
Impacts of windfarm construction on harbor porpoises
7 May 2018 at 4:42am
Scientists from Germany, Denmark and the UK have built a model tool to predict what happens to marine animals when exposed to noise from the construction and operation of wind farms at sea.
Novel approach for photosynthetic production of carbon neutral biofuel from g...
3 May 2018 at 11:27am
Reducing carbon emissions in order to prevent climate change requires developing new technologies for sustainable and renewable biofuel production. Molecular hydrogen is regarded as one of the most promising energy carriers due to its high energy density and clean, carbon-free use. A research group has discovered an efficient way for transforming solar energy into the chemical energy of biohydrogen through the photosynthesis of green algae that function as cell factories.
Natural gas prices, not 'war on coal,' were key to coal power decline
3 May 2018 at 11:27am
Steep declines in the use of coal for power generation over the past decade were caused largely by less expensive natural gas and the availability of wind energy -- not by environmental regulations.
Engineers upgrade ancient, sun-powered tech to purify water with near-perfect...
3 May 2018 at 11:26am
The idea of using energy from the sun to evaporate and purify water is ancient. The Greek philosopher Aristotle reportedly described such a process more than 2,000 years ago. Now, researchers are bringing this technology into the modern age, using it to sanitize water at what they report to be record-breaking rates.
Harvesting clean hydrogen fuel through artificial photosynthesis
3 May 2018 at 11:26am
A new, stable artificial photosynthesis device doubles the efficiency of harnessing sunlight to break apart both fresh and salt water, generating hydrogen that can then be used in fuel cells.
