Novel and cost-effective drilling technologies for geothermal systems

Geothermal is currently the most underutilized of renewable resources, even though it is in principle, via engineered geothermal systems (also called enhanced geothermal systems, EGS), possible to exploit anywhere. A key issue with deep geothermal exploitation is its high cost, with 53% of the price of exploitation expended on drilling....

Utilizing 2D crystals in methanol fuel cells

Fuel cells are a technology of interest as future energy sources, as they aid in production of sustainable energy using simple hydrocarbons as fuels. They function by a simple operational mechanism with fuel oxidation on one side, and oxidant reduction on the other side of a membrane, liberating electrons thus...

Graphene-Perovskite solar cells exceed 18% efficiency

Scientists have created hybrid perovskite-graphene solar cells that show good stability upon exposure to sunlight, while still maintaining efficiency over 18% - the highest reported efficiency of graphene perovskite hybrid solar cells to date. Perovskite solar cells (PSCs) are rapidly emerging as the most promising photovoltaic technology, gaining attention on...

Graphene for catalysis

Marko Spasenovic

Catalysis plays a major role in today’s society, impacting an estimated 90% of all commercially produced chemical products. Generating about a trillion USD in products worldwide, catalysis is used in energy processing (petroleum refining, steam reforming, automotive catalytic conversion, fuel cells), bulk and fine chemical manufacturing, food processing, and environmental...
