Development of the world’s hydropower is controversial because of its many documented environmental and societal implications. A global assessment of the unused profitable hydropower potential is performed with strict criteria to limit the environmental and social impact.
The development of hydropower offers a renewable energy source that can help reduce society’s dependence on fossil fuels. A global assessment of the unused profitable hydropower potential can be performed by incorporating strict constraints to identify hydropower station locations with reduced environmental and societal impacts.
The design of an electrochemical system without electrolytes allows hydrogenation of oxidized contaminants in water without the introduction of additional chemicals.
Electrocatalytic hydrogenation is an efficient process for treating oxidized contaminants in water. The use of a rhodium nanoparticle-modified palladium membrane electrochemical reactor presents a practical, safe and efficient approach to the treatment of water and can be applied to the hydrogenation of 12 different oxidized contaminants.
Efficient ways to disinfect water from bacterial contamination are essential for public health. Locally enhanced electric field treatment can be used to induce ultrafast bacteria inactivation with nanosecond electrical pulses.
