Engineers at The Ohio State University are developing technologies that have the potential to economically convert fossil fuels and biomass into useful products including electricity without emitting carbon dioxide to the atmosphere.

Many of the more than 200 remote communities in Alaska are turning to renewable energy to reduce reliance on high-cost imported fuels, and to ensure more independent and reliable energy availability based on local sources. Alaska is home to a substantial fraction of the developed microgrids in the world. Incorporating grid-scale levels of renewably sourced generation, such as wind and solar power, has led to an unusual concentration of experience and expertise in the design, development, and operation of these hybrid renewables-diesel microgrids.

A joint research team, affiliated with UNIST has introduced the Hybrid-Solid Electrolysis Cell (Hybrid-SOEC) system with highest reported electrochemical performance in hydrogen production. The proposed system has attracted much attention as a new promising option for the cost-effective and highly-efficient hydrogen production, as it shows excellent performance compared with other water-electrolysis systems.

Across the U.S., the energy and agricultural industries are battling it out over whether to place solar panels or crops on large stretches of flat, sunny land. Now, a new study finds that developing solar energy arrays on alternative sites like buildings, lakes, and contaminated land would allow California to meet its 2025 electricity demands without sacrificing farmland.

The worldwide quest by researchers to find better, more efficient materials for tomorrow’s solar panels is usually slow and painstaking. Researchers typically must produce lab samples — which are often composed of multiple layers of different materials bonded together — for extensive testing.

As a short-lived climate forcer, black carbon aerosols in the atmosphere play a vital role in climate change by absorbing solar radiation and altering the formation, lifespan and albedo of clouds. It also provides "seed" for haze formation in urban/regional scale. In northern China, open biomass burning (OBB), such as straw burning after harvesting, is one of important sources of refractory black carbon (rBC). OBB emits both soot particles and substantial amount of semi-volatile organic matters, both of which will undergo a very complicated mixing and evolution processes in the atmosphere to change their ability to form cloud condensation nuclei.

 In the next century, wind resources may decrease in many regions of the Northern Hemisphere and could sharply increase in some hotspot regions down south, according to a study by University of Colorado Boulder researchers. The first-of-its-kind study predicting how global wind power may shift with climate change appears today in Nature Geoscience.

Equivalent of 183,000 football fields of nonagricultural land identified in study aiming to ease competition between farmers, conservationists, and energy companies.

China has released plans to create the world’s largest carbon emissions trading scheme, several news outlets reported. The market will initially be focused on the power sector, which produced almost half of the country’s greenhouse gas emissions last year, and will encompass 1,700 energy suppliers producing more than 3 billion tons of CO2 annually, according to Reuters.

Unconventional spaces could be put to use generating renewable energy while sparing lands that could be better used to grow food, sequester carbon and protect wildlife and watersheds, says a study led by the University of California, Davis.
