New Light and Energy Tech

Silvija Gradečak has big intentions for small ingredients. The associate professor of materials science and engineering focuses on energy-conversion and light-harvesting through the use of nanomaterials. It’s at these microscopic scales that she can customize components, meld parts, and create new materials.[read more]

Running on Waste Heat

Waste Heat and Power

It’s estimated that more than half of U.S. energy — from vehicles and heavy equipment, for instance — is wasted as heat. Mostly, this waste heat simply escapes into the air. But that’s beginning to change, thanks to thermoelectric innovators such as MIT’s Gang Chen.[read more]

Siva Power's Thin Film Cost Target of 28 Cents per Watt Is Very Ambitious. But Not Impossible

Siva Power and Cost Targets

Siva Power, the CIGS thin film company that re-emerged last year with a new team and approach to the market, is out with an ambitious cost roadmap for its modules. Before getting into the details of Siva's plan, it's worth remembering one important number related to CIGS thin film: twenty.[read more]

Wireless Energy Future

More than a century ago, engineer and inventor Nikola Tesla proposed a global system of wireless transmission of electricity — or wireless power. But one key obstacle to realizing this ambitious vision has always been the inefficiency of transferring power over long distances.[read more]

Novel Bromine Battery: Small-Scale Demo, Large-Scale Promise

July 2, 2014 by Energy @ MIT

Battery and Storage Innovation

The availability of low-cost, high-capacity energy storage technology could profoundly change today’s energy landscape. The ability to store electricity when supplies are abundant and deliver it later when they’re not would permit widespread use of intermittent sources such as solar and wind.[read more]

Energy Storage Opportunities are Everywhere

Green Gas and Intermittency

Albert van der Molen recently faced a quandary. As Innovation Leader for Stedin, the third-largest grid operator in the Netherlands, his job includes improving electricity and natural gas delivery while expanding the utility’s use of renewable energy.[read more]

Improving a New Breed of Solar Cells

May 29, 2014 by Energy @ MIT

New Solar Cells

Solar-cell tech has advanced rapidly, as hundreds of groups around the world pursue more than two dozen approaches using different materials, technologies, and approaches to improve efficiency and reduce costs. Now a team at MIT has set a new record for the most efficient quantum-dot cells.[read more]

A New Way to Make Sheets of Graphene

Graphene Production Innovation

Graphene’s promise as a material has led researchers around the world to study the material in search of new applications. But one of the biggest limitations to wider use of the strong, lightweight, highly conductive material has been the hurdle of fabrication on an industrial scale.[read more]

Getting More Electricity out of Solar Cells

May 9, 2014 by Energy @ MIT

Solar Cell Efficiency

When sunlight shines on today’s solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons — behavior that could significantly increase solar-cell efficiency.[read more]

The Electric Utility Singularity

February 11, 2014 by Christine Hertzog

A singularity is a term that is used in mathematics, physics, and advanced artificial intelligence. The definitions vary based on perspective, but in simple terms, it signifies the point where old rules break down. This is exactly where electric utilities are now.[read more]

Could Hybrid Nuclear Plants Help Stem Global Warming?
