Polar Night Energy has developed a thermal energy storage system which supplements renewable energy sources and reduces our ...

As global energy demand accelerates, one truth remains underappreciated: heat is the largest end use of energy. Today, more than 50 percent of global final energy consumption is dedicated to ...

Heat batteries quietly solve a major transition gap, storing surplus renewable electricity as heat.

The community swimming pool in the Finnish town of Kankaanpää is heated with sand—well, a sand battery, to be more specific. Energy utility Vatajankoski has partnered with Polar Night Energy, a ...

A Finnish-Swedish consortium has designed a hybrid system that uses photovoltaics and solar thermal energy separately to provide steam to industrial facilities. The PV unit is coupled to a sand-based ...

Lithium-ion batteries dominate headlines, but most global energy storage relies on simpler methods. These methods include pumped hydro, compressed air, gravity, and thermal storage using sand or rock.

A research group from Ghana has developed a solar PV-powered steam cooker (ISESC) with sand-based thermal energy storage (TES). “The potential of sand, given its thermal stability and low cost, has ...

Homerun Resources Inc (OTCQB:HMRFF) has signed a multi-party shared resource/funds-in Cooperative Research and Development Agreement (CRADA) with the U.S. Department of Energy’s National Renewable ...

For more than a century, fossil fuel companies have drilled oil and gas wells to increase the production, consumption, and export of fossil fuels. These wells are often abandoned once they are no ...
