U.S. scientists have developed what they say is the first integrated nanosystem capable of replicating the process of photosynthesis, a sort of “artificial forest” that could one day lead to the production of hydrogen that could be used to power fuel cells.

Composed of nanowire structures — including silicon (more…)

According to a recent joint University of Delaware and Delaware Technical Community College study, a well-designed combination of wind energy, solar energy, and storage in batteries and fuel cells would be a cost effective way of meeting electricity demands. (more…)

In a previous post, I wrote about the New Energy Symposium held last month in New York City. The first day of the event featured a startup quick pitch competition, and the three winners of the competition were recently announced.

They are, in alphabetical order, Dynamo Micropower, (more…)

Our Green Off-Patent Report provides selected highlights of green patents which have completed their 20-year terms and recently expired or will complete their terms and expire within the next week or so (assuming the patentee paid all requisite maintenance fees; U.S. patents require payment of fees 3 1/2, 7 1/2, and 11 1/2 years after issuance to stay in force). (more…)

You can see lots of attention is focused towards alternative and renewable energy systems. This is due to the soaring energy costs and the need to decrease the climate change effects over earth. Though these solutions may seem complicated for the homeowners in their daily chores, however, the fact is that they are now becoming more accessible to common man. (more…)

A semiconductor is a material with electrical conductivity intermediate in magnitude between that of a conductor and an insulator. Semiconductor materials are the foundation of modern electronics, including radio, computers, telephones, and many other devices. Such devices include transistors and digital and analog integrated circuits. Transition metal oxides also (more…)

Here’s something I’ve noticed from the process of participating in a large number of energy-related conversations at the American Chemical Society Conference: some of these subjects, even those receiving funding, have virtually no chance of practical application. (more…)

Earlier this year, the California Air Resources Board (CARB) completely revamped its passenger vehicle emissions control regulations. The new Advanced Clean Cars program, which covers model years 2017–2025, combines several regulatory schemes into the new program: the Low Emission Vehicle (LEV) program, which governs tailpipe (more…)

While we are seeing many exciting new developments every day in green technologies, one of the interesting features of the current cleantech boom is its reliance on mature technologies such as solar PV and wind, which went through prior periods of innovation in the 1970s and ’80s.

Thus, many of the green technologies in use today are (more…)

The U.S. Department of Energy’s (DOE) Fuel Cell Technologies Program has issued an RFI (Request for Information) seeking feedback from stakeholders regarding the commercial readiness of fuel cell and hydrogen technologies.

DOE is interested in industry information about (more…)
