New German ecoPtG project seeks to make power-to-gas commercially viable with help of automotive technology
February 04, 2016
In collaboration with engineering partner IAV, the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW); the Reiner Lemoine Institut (RLI); and Wasserelektrolyse Hydrotechnik (HT) are researching cost-effective methods of producing hydrogen with the help of automotive technology. In the ecoPtG project, the researchers and engineers are developing an alkaline water electrolyzer with an output of 100 kW. They aim to demonstrate that CO2-neutral hydrogen can be produced in a cost-effective manner and intend to facilitate the storage of electricity.
Electricity is increasingly being generated from fluctuating renewable sources. Solar and wind energy generation depends on the weather and is subject to significant fluctuations. At times, renewable energy production thus temporarily exceeds regional demand. Hydrogen produced according to the power-to-gas method can play a role in resolving this challenge and decarbonizing the transport sector. By converting electricity to gas, solar and wind power become storable. If required, hydrogen can be reconverted or used as environmentally compatible fuel for fuel cell vehicles.
Purdue, EPFL team propose Hydricity concept for integrated co-production of H2 and electricity from solar thermal energy
December 16, 2015
Researchers from Purdue University and École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are proposing a new integrated process involving the co-production of hydrogen and electricity from solar thermal energy—a concept they label “hydricity”. They describe their proposal in a paper in the Proceedings of the National Academy of Sciences (PNAS).
The hydricity process entails integrating solar water power (SWP) cycle and solar thermal hydrogen production technologies and a turbine-based hydrogen power cycle with suitable improvements of each for compatibility and beneficial interaction.
Study finds EV deployment in China to increase Environmental Justice challenge there
November 16, 2015
A new study by a team from the University of Tennessee, Tsinghua University and the University of Minnesota has found that the wide-scale deployment of electric vehicles in China can increase the Environmental Justice (EJ) challenge in that country.
According to their findings, published in a paper in the ACS journalEnvironmental Science & Technology, most (∼77%, range: 41–96%) emission inhalation attributable to urban EVs use—i.e., from the shifting of transportation’s air pollution from urban tailpipes to rural power plants—is distributed to predominately rural communities the incomes of which are on average lower than the cities in which the EVs are used.
California Hydrogen Business Council says a robust P2G RD&D program should be a priority for the state
October 14, 2015
The case for using Power-to-Gas solutions to store renewable energy is compelling for a number of important use cases, according to a new white paper released by the California Hydrogen Business Council (CHBC). The paper, —“Power-To-Gas: The Case For Hydrogen”—outlines the feasibility and economics of renewable energy storage solutions using P2G. Among the paper’s conclusions is that a robust P2G RD&D program should be a priority for the state of California. Currently, P2G is being deployed in Europe and Canada but is only at the early demonstration phase in California.
P2G systems use electrolysis powered by renewable energy to split water into hydrogen and oxygen—i.e., P2G converts electrical energy to chemical energy in the form of hydrogen. The hydrogen can then be transported through the natural gas grid via blending or further conversion to methane, transported by other means such as trucks, or used directly at the point of production.

DOE awards ~$25M to 8 projects for CO2 capture and compression; $15M for novel Direct Fuel Cell system
September 02, 2015
The US Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has selected eight projects to receive almost $25 million in funding to construct small- and large-scale pilots for reducing the cost of CO2 capture and compression through DOE’s Carbon Capture Program. More than half of the funding ($15 million) will go to FuelCell Energy for a pilot scale project using one of the company’s Direct Fuel Cells for carbon capture and compression.
The DOE’s Carbon Capture Program consists of two core research technology areas, post-combustion capture and pre-combustion capture, and also supports related CO2 compression efforts. Current research and development efforts are advancing technologies that could provide step-change reductions in both cost and energy penalty compared to currently available technologies.

The cost of producing electricity from renewable sources such as wind and solar has been falling for several years. A new report, a joint project by the International Energy Agency and the Nuclear Energy Agency, provides in detail the contrasting costs for different power generation technologies around the world and shows that renewable sources can produce electricity at close to or even below the cost of new fossil fuel-based power stations, depending upon conditions such as resources and appropriate market and regulatory frameworks.
The report, Projected Costs of Generating Electricity: 2015 Edition, also shows that new nuclear power plants generate electricity more cheaply than other established “baseload” sources—mainly coal- and gas-fired power plants—over the full lifetime of facilities when financing costs are relatively low.
MIT team proposes ARC fusion reactor: affordable, robust, compact
August 10, 2015
Advances in magnet technology have enabled researchers at MIT to propose a new design for a practical compact tokamak fusion reactor that might be realized in as little as a decade: the ARC (affordable, robust, compact) reactor. The stronger magnetic field makes it possible to produce the required magnetic confinement of the superhot plasma—the working material of a fusion reaction—but in a much smaller device than those previously envisioned.
The reduction in size, in turn, makes the whole system less expensive and faster to build, and also allows for some ingenious new features in the power plant design. The proposed tokamak (donut-shaped) reactor is designed to have 500 MW fusion power at 3.3 m major radius and is described in a paper in the journal Fusion Engineering and Design.
EPA releases final Clean Power Plan; 32% reduction in CO2 from power plants by 2030
August 03, 2015
The US Environmental Protection Agency (EPA) has released the final Clean Power Plan (CPP). The rules establish the first national standards to limit CO2 emissions from fossil-fuel-fired power plants, with a target of a 32% reduction against a 2005 baseline by 2030. The 32% reduction target is 9% more aggressive than in the draft proposal of the CPP released in 2014. (Earlier post.)
The 2030 target is in alignment with the Administration’s earlier economy-wide emissions targets, including the goal of reducing emissions to 17% below 2005 levels by 2020 and to 26-28% below 2005 levels by 2025. Under the Clean Power Plan, by 2030, renewables will account for 28% of national capacity, up from 22% in the proposed rule.

The projects selected under the two FOAs will receive funding through NETL’s Solid Oxide Fuel Cell Program. The FOAs were awarded with two primary objectives: to design, construct, and field-test a SOFC prototype system; and to support innovations that improve the reliability, robustness, and endurance of SOFC cell and stack technology.
Tire-integrated triboelectric generator harvests electricity from rolling tire friction; est. up to +10% fuel econ
June 30, 2015
A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a triboelectric nanogenerator (TENG) that harvests energy from a car’s rolling tire friction. An innovative method of reusing energy, the nanogenerator ultimately could provide automobile manufacturers a new way to squeeze greater efficiency out of their vehicles.
The TENG is a novel energy harvesting device to convert mechanical energy into electricity based on the universally known triboelectric principle—i.e., the generation of an electric charge resulting from the contact or rubbing together of two dissimilar objects. Specifically, the nanogenerator relies on the triboelectric effect to harness energy from the changing electric potential between the pavement and a vehicle’s wheels.

These projects have been selected for negotiation of awards; final award amounts may vary.
Global investment in renewable power reached $270.2B in 2014, ~17% up from 2013; biofuel investment fell 8% to 10-year low
April 06, 2015
Global investment in renewable power and fuels (excluding large hydro-electric projects) was $270.2 billion in 2014, nearly 17% higher than the previous year, according to the latest edition of an annual report commissioned by the United Nations Environment Program’s (UNEP) Division of Technology, Industry and Economic (DTIE) in cooperation with Frankfurt School-UNEP Collaborating Centre for Climate & Sustainable Energy Finance and produced in collaboration with Bloomberg New Energy Finance.
This marked the first annual increase in dollar commitments to renewables—excluding large hydro—for three years, and brought the total up to just 3% below the all-time record of $278.8 billion set in 2011. The increase reflected several influences, according to the report, including a boom in solar installations in China and Japan—totalling $74.9 billion between those two countries—and a record $18.6 billion of final investment decisions on offshore wind projects in Europe.
U Toronto LCA suggests that with CNG as primary vehicle energy source, EVs best targeted at non-attainment areas
April 01, 2015
A team at the University of Toronto has examined the life cycle air emissions (climate change and human health) impact benefits and life cycle ownership costs of compressed natural gas (CNG) use directly in conventional vehicles (CV) and hybrid electric vehicles (HEV), and natural gas-derived electricity (NG-e) use in plug-in battery electric vehicles (BEV), using a gasoline-fueled conventional vehicle as a reference.
Among their findings, published in a paper in the ACS journal Environmental Science & Technology, are that policies should for the foreseeable future focus on the niche adoption of plug-in vehicles in non-attainment regions, as CNG vehicles are likely more cost-effective at providing overall life cycle air emissions impact benefits.
ORNL and Shanghai Institute of Applied Physics in CRADA for development of fluoride salt-cooled high-temp reactors
March 19, 2015
Oak Ridge National Laboratory and the Shanghai Institute of Applied Physics (SINAP) are engaged in a Cooperative Research and Development Agreement (CRADA) focused on accelerating scientific understanding and technical development of salt-cooled reactors, specifically fluoride salt-cooled high-temperature reactors (FHRs). The project will draw on ORNL’s expertise in fuels, materials, instrumentation and controls, design concepts, and modeling and simulation for advanced reactors, as well as the lab’s experience in the design, construction and operation of the Molten Salt Reactor Experiment, the only molten salt reactor ever built. (Design began in 1960, construction started early in 1962. The 7.4 MWth test reactor operated successfully from 1965 to 1969.)
Representatives from the Oak Ridge National Laboratory (ORNL) and the Shanghai Institute of Applied Physics (SINAP) are meeting at ORNL this week; SINAP staff members will describe their plans for building the first salt-cooled test reactor, and the two sides will begin planning the next steps in the shared research project.
New diamine-appended MOFs can capture CO2 for half or less of the energy cost of current materials
March 12, 2015
UC Berkeley chemists have developed a new material that can efficiently capture CO2 and then release it at lower temperatures than current carbon-capture materials, potentially cutting by half or more the energy currently consumed in the process.
The material, a metal-organic framework (MOF) modified with nitrogen compounds called diamines, can be tuned to remove carbon dioxide from the room-temperature air of a submarine, for example, or the 100-degree (Fahrenheit) flue gases from a power plant. A paper elucidating the mechanism of what the researchers are calling “phase-change” adsorbents is published in the journal Nature.
