  • Dow-like index for energy prices might help smooth transition to clean power
    on March 24, 2021 at 3:33 pm

    Since the early industrial revolution in the mid-1700s, fossil fuels have acquired an ever-growing footprint in energy production. However, the environmental concerns of fossil fuels use and their inevitable depletion have led to a global shift toward renewable energy sources. These transitions, however, raise questions about the best choice of renewables and the impact of investing in these resources on consumer cost.

  • Solar panels are contagious – but in a good way
    on April 21, 2021 at 4:45 pm

    The number of solar panels within shortest distance from a house is the most important factor in determining the likelihood of that house having a solar panel, when compared with a host of socio-economic and demographic variables. This is shown in a new study by scientists using satellite and census data of the city of Fresno in the US, and employing machine learning.

  • Green hydrogen: ‘Rust’ as a photoanode and its limits
    on April 19, 2021 at 5:57 pm

    Researchers have now analyzed the optoelectronic properties of rust (haematite) and other metal oxides in unprecedented detail. Their results show that the maximum achievable efficiency of haematite electrodes is significantly lower than previously assumed. The study demonstrates ways to assess new photoelectrode materials more realistically.

  • Sunlight to solve the world’s clean water crisis
    on April 16, 2021 at 4:01 pm

    Researchers have developed technology that could eliminate water stress for millions of people, including those living in many of the planet’s most vulnerable and disadvantaged communities.

  • Transparent nanolayers for more solar power
    on April 15, 2021 at 3:41 pm

    There is no cheaper way to generate electricity today than with the sun. Solar cells available on the market based on crystalline silicon make this possible with efficiencies of up to 23 percent. With even higher efficiencies of more than 26 percent, costs could fall further. An international working group led by photovoltaics researchers now plan to reach this goal with a nanostructured, transparent material for the front of solar cells.

  • Solar and wind power could mitigate conflict in northeast Africa
    on April 8, 2021 at 5:14 pm

    A new study shows that several disagreements between Ethiopia, Sudan and Egypt around Africa’s largest hydropower plant, the new Grand Ethiopian Renaissance Dam (GERD), could be alleviated by massively expanding solar and wind power across the region.

  • A new material enables the usage of ‘calcium’ for batteries
    on April 6, 2021 at 4:07 pm

    Scientists have developed a new fluorine-free calcium (Ca) electrolyte based on a hydrogen (monocarborane) cluster that could potentially realize rechargeable Ca batteries.

  • This hydrogen fuel machine could be the ultimate guide to self-improvement
    on April 5, 2021 at 4:33 pm

    Scientists have uncovered an extraordinary self-improving property that transforms an ordinary semiconductor into a highly efficient and stable artificial photosynthesis device.

  • Small robot swimmers that heal themselves from damage
    on March 24, 2021 at 3:35 pm

    Living tissue can heal itself from many injuries, but giving similar abilities to artificial systems, such as robots, has been extremely challenging. Now, researchers have developed small, swimming robots that can magnetically heal themselves on-the-fly after breaking into two or three pieces. The strategy could someday be used to make hardier devices for environmental or industrial clean up, the researchers say.

  • New porous material promising for making renewable energy from water
    on March 22, 2021 at 3:29 pm

    One prospective source of renewable energy is hydrogen gas produced from water with the aid of sunlight. Researchers have developed a material, nanoporous cubic silicon carbide, that exhibits promising properties to capture solar energy and split water for hydrogen gas production.

  • Double-duty catalyst generates hydrogen fuel while cleaning up wastewater
    on March 17, 2021 at 6:17 pm

    Hydrogen is a pollution-free energy source when it’s extracted from water using sunlight instead of fossil fuels. But current strategies for ‘splitting’ or breaking apart water molecules with catalysts and light require the introduction of chemical additives to expedite the process. Now, researchers have developed a catalyst that destroys medications and other compounds already present in wastewater to generate hydrogen fuel, getting rid of a contaminant while producing something useful.
