The Swiss company, Center for Electronics and Microtechnology (CSEM), has announced that they have developed the world’s first white solar modules. According to the company, this will allow for a more visually appealing solar module, which will blend into buildings to become virtually invisible.

The current blue-black solar modules are built to maximize sunlight absorption, whereas a white solar module was previously not a color option due to the fact that the color would generally reflect light, rather than absorbing it.

This from CSEM:

CSEM has developed a new technology to make white solar modules, with no visible cells and connections, a reality. It combines a solar cell technology able to convert infrared solar light into electricity and a selective scattering filter, which scatters the whole visible spectrum while transmitting infrared light. Any solar technology based on crystalline silicon can now be used to manufacture white – and colored – modules.

Norwegian entrepreneur, Jostein Eikeland, is finally unveiling the development his has been working on in secret for the past decade in hopes to jolt the world of energy storage.

Eikeland and his company Alevo plan to reveal a battery that will last longer and cost far less than the current rival technologies. To do this, they have developed a technology that is to store excess electricity generated by power plants.

This from Reuters:

The company has created what it calls GridBanks, which are shipping containers full of thousands of battery cells. Each container can deliver 2 megawatts of power, enough to power up to 1,300 homes for an hour. The batteries use lithium iron phosphate and graphite as active materials and an inorganic electrolyte – what Eikeland called the company’s “secret sauce” – that extends longevity and reduces the risk of burning. They can be charged and discharged over 40,000 times, the company said.

It’s a good day for renewable resources.

According to a jointly written report of solar photovoltaic systems (PV) pricing trends from the Energy Department’s (DOE) National Renewable Energy Laboratory (NREL) and Lawrence Berkeley National Laboratory (LBNL), prices have dropped by 12 to 19 percent nationwide in 2013.

The report goes on to state that prices are expected to drop an additional 3 to 12 percent in 2014. The variation in percentage is dependent on the system location and market segment.

Researcher used microscopy to take an atomic-level look at a cubic garnet material called LLZO that could help enable higher-energy battery designs.

The quest for better batteries is an ongoing trend, and now the researchers from the Department of Energy’s Oak Ridge National Laboratory (ORNL) have yet another development to add.

During their research, the scientists found exceptional properties in a garnet material. They now believe that this could lead to the development of higher-energy battery designs.

This from ORNL:

The ORNL-led team used scanning transmission electron microscopy to take an atomic-level look at a cubic garnet material called LLZO. The researchers found the material to be highly stable in a range of aqueous environments, making the compound a promising component in new battery configurations.

Read the full article here.

While most researcher tend to use a pure lithium anode to improve a battery’s energy density, the ORNL scientists believe the LLZO would be an ideal separator material.

“Many novel batteries adopt these two features [lithium anode and aqueous electrolyte], but if you integrate both into a single battery, a problem arises because the water is very reactive when in direct contact with lithium metal,” said ORNL postdoctoral associate Cheng Ma, first author on the team’s study published in Angewandte Chemie. “The reaction is very violent, which is why you need a protective layer around the lithium.”

With developments such as these, which lead to higher-energy batteries – we begin to improve electrified transportation and electric grid energy storage applications. Due to the importance of higher-energy batteries, researchers tend to explore battery designs beyond the limits of lithium-ion technologies.

A few days ago we talked about fusion reactors and the new development out of the University of Washington that hopes to makes fusion a reality. Now we’re talking fusion again – only on a much different scale.

Lockheed Martin is making headlines for their announcement that their compact fusion reactors could be functional within one decade.

The company has been working for some time to develop a source of infinite energy, and have been devoting much time to fusion due to its clean and safe properties.

Their work on compact fusion revolves around the idea of using a high fraction of the magnetic field pressure, or all of its potential, to make devices much smaller than previous concepts. If they can achieve this, a reactor small enough to fit on a truck could provide enough power for a small city of up to 100,000 people.

Fusion energy appears to be the future of energy storage – or at least it should be. Fusion energy yields zero greenhouse gas emissions, no long-lived radioactive waste, and a nearly unlimited fuel supply.

Up until this point, there has been an economic roadblock in producing this type of energy. The designs that have been penciled out to create fusion power are too expensive and won’t feasibly outperform systems that use fossil fuels.

Now, the engineers at the University of Washington (UW) are hoping to change that. They have designed a concept for a fusion reactor, that when scaled up, would rival costs of fossil fuel plants with similar electrical outputs.

This from the University of Washington:

The design builds on existing technology and creates a magnetic field within a closed space to hold plasma in place long enough for fusion to occur, allowing the hot plasma to react and burn. The reactor itself would be largely self-sustaining, meaning it would continuously heat the plasma to maintain thermonuclear conditions. Heat generated from the reactor would heat up a coolant that is used to spin a turbine and generate electricity, similar to how a typical power reactor works.

Read the full article here.

Currently, the University of Washington’s concept is about one-tenth the size and power output of a final product, which would still be years away.
