In-flight, on-demand hydrogen production could mean ‘greener’ aircraft

Read the full story in Science Daily.

Technion researchers have developed a safe and efficient way to produce hydrogen on board a plane in flight. Using aluminum particles and water (fresh or waste), the technology could one day help meet in-flight energy needs on commercial aircraft.

Novel Method Turns Methanol into Renewable Energy

Read the full story in R&D Magazine.

A new renewable energy source might come from the world’s simplest alcohol.

A team of researchers from the University of Southern California, led by senior author G. K. Surya Prakash and 1994 Nobel Prize winner George Olah, have created a carbon-neutral method to produce and store hydrogen from methanol, without concurrent production of either carbon monoxide or carbon dioxide…

The study was published in The Journal of the American Chemical Society. It represents Olah’s last major paper as he passed away on March 8, 2017.

Should we link investment in renewable energy to fossil-fuel subsidy reform?

Read the full story at Environmentalresearchweb.

Supporting renewable-energy deployment rather than continuing to subsidize fossil-fuel-derived electricity could deliver fiscal benefits to countries with high-cost electricity systems such as Lebanon or Saudi Arabia. That’s one of the findings of a study by a team in Switzerland published in Environmental Research Letters (ERL).

Webinar: Tools for Building More Resilient Communities with Solar+Storage

Thu, Apr 6, 2017 12:00 PM – 1:30 PM CDT

Could your community benefit from clean, reliable power? In this webinar, Clean Energy Group will reintroduce the concept of building more resilient communities through the deployment of solar PV combined with battery storage (solar+storage). In addition to an overview of what resilient power is and the benefits that solar+storage can bring to a community, project director Seth Mullendore and senior finance director Rob Sanders will introduce Clean Energy Group’s new Resilient Power Toolkits. These community services and affordable housing toolkits are designed to make information on resilient power easily accessible for organizations interested increasing resiliency, reducing energy costs, and improving public health through clean energy technologies. The Resilient Power Toolkits are available at:

Electricity: Status of Residential Deployment of Solar and Other Technologies and Potential Benefits and Challenges

What GAO Found

Federal and state policymakers have used a range of policies to encourage the deployment of solar systems and other technologies that allow residential customers to generate, store, and manage their electricity consumption. For example, federal tax incentives—such as the investment tax credit—have reduced customers’ up-front costs of installing solar systems. In addition, a Department of Energy funded database of renewable energy incentives identifies 41 states with net metering policies that require electricity suppliers to credit customers for electricity sent from their solar systems to the grid, providing an additional incentive. Moreover, in 14 states, customers can also receive state tax credits for installing solar systems, according to the database, which further reduces the up-front costs.

According to GAO’s analysis of Energy Information Administration (EIA) data, deployment of solar systems has increased significantly in some states, with the total number of residential customers with solar systems increasing sevenfold from 2010 to 2015. However, customers with solar systems represent a very small portion of overall electricity customers—about 0.7 percent of U.S. residential customers in 2015, according to EIA data. Every state experienced growth in the number of customers with residential solar systems, although certain states, such as California and Hawaii, accounted for most of the growth and have had more widespread deployment. For example, about 14 percent of residences in Hawaii have installed a solar system, according to EIA data. Although comprehensive data on the deployment of electricity storage systems and smart devices are not available, the data and information provided by stakeholders GAO interviewed suggest their deployment is limited.

The increasing residential deployment of solar systems and other technologies poses potential benefits and challenges, and some policymakers have implemented or are considering measures to address these, as GAO found in its analysis of reports and stakeholder interviews. Specifically, these technologies can provide potential benefits through more efficient grid operation, for example, if customers use these technologies to reduce their consumption of electricity from the grid during periods of high demand. Nonetheless, grid operators GAO interviewed said they have begun to confront grid management and other challenges in some areas as solar deployment increases. For example, in some areas of Hawaii, solar systems have generated more electricity than the grid was built to handle, which resulted in the need for infrastructure upgrades in these areas. However, grid operators reported that challenges generally have been manageable because overall residential solar deployment has been low. Policymakers in some states have implemented or are considering measures to maximize potential benefits and mitigate potential challenges associated with the increasing deployment of these technologies. For example, two states’ regulators have required electricity suppliers to identify areas of the grid where solar and other technologies would be most beneficial to grid operation. In addition, several state regulators recently have allowed electricity suppliers to adopt voluntary time-based electricity prices that increase when demand for electricity is high, providing customers with an incentive to reduce consumption at these times, potentially by using solar, storage, and other technologies.

Why GAO Did This Study

Traditionally, electricity has moved in one direction—from electricity suppliers to customers. Today, solar systems allow electricity to be generated at a customer’s home and sent to the grid for electricity suppliers to use to meet other customers’ electricity needs. Storage systems allow residential customers to store electricity from the grid or their own solar system for use at a later time. Furthermore, customers can use smart devices, such as thermostats, to manage their electricity consumption.

GAO was asked to provide information on the deployment and use of technologies that give customers the ability to generate, store, and manage electricity. This report describes (1) key federal and state policies used to encourage the deployment of these technologies, (2) the extent to which these technologies are being deployed, and (3) the benefits and challenges of deploying these technologies. GAO analyzed available data on technology deployment from EIA and reviewed relevant reports and regulatory documents. GAO interviewed a non-generalizable sample of 46 government agencies and stakeholder organizations. This sample included state regulators and at least one electricity supplier from each of five states: Arizona, California, Hawaii, Minnesota, and New York, which were selected based on state policies and having high levels of technology deployment.

GAO is not making recommendations in this report.
