Hydrogen-Powered Transport In Britain | Earth Wise

November 27, 2020 By EarthWise Leave a Comment

The first hydrogen-powered train in the UK had its first mainline runs at the end of September. The train, known as HydroFLEX, was developed under a project headed by the University of Birmingham under the UK government’s Department for Transport.

Hydrogen-powered trains do not emit harmful gases but rather use hydrogen and oxygen to produce electricity, water, and heat. The technology in the HydroFLEX train will be available by 2023 to retrofit existing diesel-powered trains and thereby de-carbonize the rail network and make train travel greener and more efficient.

The UK has ambitious plans for the use of hydrogen technology. The Department of Transport plans to publish a master plan in January that will outline how green hydrogen could power buses, trucks, rail, maritime, and aviation transport across the UK.

The HydroFLEX trial is taking place in Tees Valley in northeastern England and the plan is for that area to become a Hydrogen Transport Hub that will include the world’s largest versatile hydrogen refueling facility. The plans for Tees Valley involve academia, industry, and government participants. The next stages of the HydroFLEX project are well underway with the University of Birmingham developing a hydrogen and battery-powered module that can be fitted underneath a train to allow for more space for passengers in train cars.

The UK government’s Hydrogen for Transport Program is also funding a green hydrogen refueling station and 19 hydrogen-powered garbage trucks in Glasgow, Scotland.

The UK plans to switch to a net zero economy and their current program increasingly embraces hydrogen technology to provide more sustainable, greener forms of transportation.

Benefits Of A Zero-Emissions Boston | Earth Wise

May 25, 2020 By EarthWise Leave a Comment

Many countries, states, and cities around the world have set goals to become carbon neutral, typically by the year 2050. These goals are based on the desire to mitigate the effects of climate change that are steadily increasing as a result of the buildup of carbon dioxide in the atmosphere. But reducing emissions is not just a way to combat climate change, it can also be a major contributor to improved public health.

The City of Boston has set a goal to become carbon neutral by 2050. A new study by the School of Public Health at Boston University published in the journal Environmental Research Letters looked at the consequences of eliminating fossil fuel emissions in the greater Boston area.

According to their modeling, eliminating emissions would save 288 lives a year by reducing fatal and non-fatal cardiovascular and respiratory illnesses. The resulting decrease in medical costs and lost and reduced work could save $1.7 billion a year in Suffolk County and $2.4 billion a year for the entire 75-square-mile zone modeled in the study.

The study looked at the amounts of two air pollutants known to harm human health: PM2.5 (particulates with a diameter of less than 2.5 microns) and ozone. They compared the current levels of these pollutants to what would be present when contributions from motor vehicles, generators, rail, industry, oil- and gas-burning, shipping and boating, and residential wood fires were eliminated.

The study focused on the City of Boston’s climate action plan, but actions taken by Boston will not take place in a vacuum. Many cities across the region are taking similar actions. The overall results will come from the collective actions across New England.

Recycling Coal Plants | Earth Wise

April 27, 2020 By EarthWise Leave a Comment

Over 300 coal-fired power plants in the US have stopping burning coal over the past decade. Only about 224 plants still produce power by burning coal. As a result, a new sort of recycling industry is taking shape: repurposing of coal plants.

Across the country, utilities are finding ways to redevelop these facilities. Some are industrial in nature and others a far cry from their original purpose.

In January, Beloit College in Wisconsin opened a student union and recreation center in what used to be an Alliant Energy coal-fired power plant. On the southern coast of Massachusetts, a shuttered 1,600 MW coal plant is being demolished to make way for a logistical port and support center for a planned wind farm 35 miles off shore.

In Independence, Missouri, the city is considering competing plans to recycle the Blue Valley Power plant. It may become a 50 MW battery storage facility, or possibly a biofuel plant.

Another popular reuse strategy is data centers. Data centers use tremendous amounts of power and therefore can make use of the former coal plants’ capacity to handle large amounts of electricity.

Retired coal-fired plants have built-in infrastructure and components that can be repurposed for new industry. The plants typically have access to rail, ports and waterways, as well as proximity to good highway transportation. The electrical grids to which they are connected can be reused for solar or wind farms at the site.

Given that coal plants are continuing to close, the potential to redevelop them in various ways continues to grow as well. There is a surge in interest in coal plant redevelopment because these facilities are assets of value.

A Hydrogen-Powered Train

June 5, 2017 By EarthWise

It seems like something out of a science fiction movie, but a nearly silent train that glides along its tracks emitting nothing but water is a reality. In March, Germany conducted successful tests of the world’s first “Hydrail,” which is a hydrogen-powered, zero-emission train.
