Natural gas pipeline in Germany holds “green” methane; Austria has similar plans

A Düsseldorf, Germany-based energy company called Uniper announced last week that it sent methane made from renewable hydrogen into the local natural gas pipeline.

The methanation plant in Falkenhagen that made the synthetic methane opened in May 2018 (PDF), and the plant's operators began testing the process to combine renewable hydrogen with carbon dioxide from a nearby bioethanol plant.

The synthetic methane is sent into the local natural gas pipeline, where it's used along with traditional natural gas. "Today, the plant produces up to 1,400 cubic meters of synthetic methane (SNG) per day, which corresponds to approximately 14,500 kWh [kilowatt hours] of energy," a Uniper press release noted.

States will vote on these energy and environment issues in midterm elections

In the United States, mid-term elections are set to take place on Tuesday November 6. Although much of the limelight is on Congressional races and gubernatorial races, US citizens also have the chance to vote on some important initiatives, measures, and amendments that are specific to their state. These state rules can often have a more direct impact on the lives of Americans than their representatives in Congress do, but because proposals tend to be long and nuanced, they also can attract a lot less attention.

Energy and environment topics are among the most contentious of 2018's ballots, especially in western states where fossil fuel interests are facing a public that's increasingly concerned with climate change. Here's a look at seven proposed rules on US state ballots that could influence state economies and environments in serious ways.

Rick Perry’s “baseload” study released, offers a lifeline to coal, nuclear

August 24th, 2017

The US Department of Energy (DOE) released a report late Wednesday night recommending that power markets revise how they value coal and nuclear power. The report also admits that low natural gas prices are a primary cause of recent coal plant closures.

The report has been controversial since its inception. In mid-April, Energy Secretary Rick Perry directed his team to study grid reliability and security for 60 days. Although the memo never mentioned renewables, it implicated “certain policies” that apparently unfairly threatened coal-burning plants.

That led critics to wonder whether renewable energy—critical for the mitigation of climate change—would get a fair shake in Perry’s study. Grid operators have been able to put a fair amount of renewable energy on the grid without reliability suffering, but the tone of Perry’s memo suggested that a conclusion contradicting that fact had been predetermined.
