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.

Toyota and public and private partners in Japan to trial renewable CO2-free hydrogen supply chain

September 08, 2015

Major corporate and public sector partners in Japan are launching an effort to test a full carbon-neutral hydrogen supply chain powered by renewable wind energy. The trials are planned to take place near the cities of Yokohama and Kawasaki in the Keihin coastal region.

On the public sector side, the project is being implemented by the Kanagawa Prefectural Government, Yokohama City, and Kawasaki City. The four private sector participants are Iwatani Corporation, Toshiba Corporation, Toyota Motor Corporation, and Toyota Turbine and Systems Inc. In addition, the project will be supported by Japan’s Ministry of the Environment.

Joint IEA-NEA report details plunge in costs of renewable electricity; nuclear competitive with other baseload power sources

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.

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.
