Geothermal Heat Extraction Process Takes Advantage of New Liquid

Scientists at the Department of Energy's Pacific Northwest National Laboratory have come up with an innovative approach that can safely and economically extract and convert heat from untapped geothermal resources. The heat recovery method makes the most of low-temperature “hot rock” resources.

Virtually Engineering Energy Conversion Plants

Photovoltaic and wind energy plants, hydroelectric power stations, and biogas plants can be complex to design and maintain. In designing a hydroelectric power station, an engineer needs to know what the pressures, temperatures, and fluid flows will be in the facility. Virtual reality makes planning and operation easier.

A Low-Cost Manufacturing Solution for CIGS-Based Solar Cells

Though the solar industry today predominately produces solar panels made from crystalline silicon, they remain relatively expensive to make. New players in the solar industry have instead been looking at panels that can harvest energy with CIGS (copper-indium-gallium-selenide) or CIGS-related materials.

First Step in Converting Solar Energy Using Artificial Leaf

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international team, headed by Leiden University professor Huub de Groot, modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria.

Feather Fibers Fluff Up Hydrogen Storage Capacity

Scientists have developed a new hydrogen storage method - carbonized chicken feather fibers - that can hold vast amounts of hydrogen, and do it at a far lower cost than other hydrogen storage systems. The research could help overcome some of the hurdles to using hydrogen fuel in cars, trucks, and other machinery.

Sensing Method Checks Refrigerant Levels, Saves Energy

A new “virtual refrigerant charge sensor" saves energy and servicing costs by indicating when air conditioners are low on refrigerant, preventing the units from working overtime. Engineers at Purdue University developed the sensing technique, which is particularly practical for automotive air conditioners.
