Coal producer Shenhua invests in sun

That molten salt can be used immediately to superheat water, or stored in insulated tanks to drive the thermal-power process during cloudy weather or at night.

Shenhua Group in China, the biggest coal producer in the world, and the American company SolarReserve intent to invest 2 billion dollars in concentrated solar power.

The aim is to realize 1GW of solar projects in China.

Students chose nuclear

Students chose nuclear to save the world

Thinking small is big deal: DOE to push US manufacturing of small modular reactors

Students chose nuclear – University of California-Berkeley professor Rachel Slaybaugh summed up the buzz around nuclear technology innovation during a recent roundtable on advanced nuclear power: “Now is an exciting time to be in nuclear energy,” she said.

 

“Nobody told today’s students that nuclear innovation is supposed to be slow. They chose nuclear because they want to save the world.

Defining how the universities facilitate collaboration between students and industry will be key to our success.”

The first Ecovat Thermo Energy Storage Tank almost ready for use

The Dutch startup Ecovat is making the energy supply in the built environment sustainable, by creating a large thermal storage tank that is able to store high temperature heat (to around 90 degrees C) over a longer period (> 6 months) with a loss of energy in this period of less than 10%.

Dr. Ir. J van Berkel (TU/e) has confirmed this in a desk research. (Report “Ecovat Thermodynamics”, March 20th, 2014).  Read More

Smart grid solutions ensure a sustainable future with renewable energy

Since April 1, 2015 the Dutch Government has given a boost to local energy experiments with a new law. With this new law, it will be easier to start a local renewable energy initiative.

A business park can start their own experiment in which they themselves monitor the electricity on site. The operator will only deliver to the connection of the grid site. The business park or a third party is responsible for the delivery to the individual companies. Read More

Green Battery Using Hydro-Pneumatics

Battery

The unit efficiently reconverts this compressed air into electricity to provide power or feed the electricity grid.

The HYPES Battery system developed uses water, air and eco-friendly materials to store, manage and convert, generated electrical energy.

This green solution could be adapted to a wide range of stationary applications.

Ingenious and eco-friendly! Read More

The future horizon looks brilliant for ultracapacitors, which already rank as a powerful alternative energy resource

UltraCapacitors news.

The energy storage market is blossoming. Because we need renewable energy storage to supply our smart electrical grids at daily moments the demand for energy is high.

Have you already heard of UltraCapacitors to store renewable energy? 

UltraCapacitors

UltraCapacitors deliver quick bursts of energy during peak power demands, then quickly store energy and capture excess power that is otherwise lost.

They efficiently complement a primary energy source in today’s applications because they discharge and recharge quickly. Read More

Smart Grid Energy storage: Flywheels

The energy in a flywheel can quickly be converted to electrical energy by which these systems often have a high power in relation to their capacity

The energy storage market is blossoming. Because we need renewable energy storage to supply our smart electrical grids at daily moments the demand for energy is high.

Energy storage by Flywheels is a storage to watch right now. 

A flywheel converts electrical energy to kinetic energy.

An electric motor/generator starts a heavy rotating disk that converts a lot of energy because of its high mechanical inertia.

The energy in a flywheel can quickly be converted to electrical energy by which these systems often have a high power in relation to their capacity. Read More

Smart Grid Battery: Compressed Air

Compressed air, energy storage

Adiabatic storage (CAES AA) not only saves electricity but also heat. This would lead up to 70% efficiency

Have you already heard of Compressed Air to store renewable energy? 

Compressed air technology compresses air at high pressure and stores it (mostly underground).

There are few projects and they are huge.

 

Economies of scale affect prices positively because increasing the storage is often associated with low marginal costs.

Molten Salt Batteries are cheap, simple and havethe potential for an infinite life

The energy storage market is blossoming. Because we need renewable energy storage to supply our smart electrical grids at daily moments the demand for energy is high.

The Molten Salt Battery is a battery to watch right now. An overview. 

In Molten Salt Batteries (also known as liquid metal batteries) two liquid electrodes are separated by a molten salt electrolyte.

Characteristic of salts is that these are guiding in the liquid state because the ions are allowed to move freely. The salt and the electrodes separate themselves by their different densities and immiscibility. Read More
