Home Depot’s Dallas DC: Running on Hydrogen

Home Depot’s Dallas DC: Running on Hydrogen

Home Depot is partnering with Plug Power to build a 1.5 million square foot distribution center in Dallas, Texas.  The new distribution center will use Plug Power’s zero-emission hydrogen fuel cell systems to power material handling equipment such as forklifts.

The fuel cell systems also become the infrastructure for storing, compressing, and dispensing hydrogen fuel.  The partnership is heralded as a fulfillment of Home Depot’s sustainability commitment to its supply chain and operations.

Maersk to Launch Carbon Neutral Cargo Ship in 2023

Maersk to Launch Carbon Neutral Cargo Ship in 2023

March 26, 2021

Maersk is the largest container shipping company in the world.  The company plans to launch the first carbon neutral cargo ship in 2023.  The company has plans to be carbon neutral by 2050.

The issue is that this new vessel will operate on methanol produced from sustainable biomass or renewable sources.  Critics point out that biofuels are not a scalable fuel solution at this time.

Mass adoption of biofuels may not be the answer given this would lead to water scarcity and threaten food security.

Walmart and Target Search for Better Bags

Walmart and Target Search for Better Bags

March 25, 2021

The debate on paper versus plastic bags to carry your items from the store to home has gone on for decades.  Reusable cloth bags have been touted as an environmentally friendly alternative.

Paper bags are extolled as coming from renewable resources, and being biodegradable.  However, they consume more energy in the production process than plastic bags.

Plastic bags consume less energy in production, but are not biodegradable.  Moreover, much has been made recently about plastic pollution, especially in our oceans.  Incredibly, the United States of America is using over 100 billion bags per years, with approximately 1% of these bags being recycled.  California and New York have banned single use plastic bags.

Reusable cloth totes require more energy to produce because they are typically heavier and stronger.  To justify their use, they need to be used around 7,100 times to equal a plastic bag’s energy usage.  Unfortunately, most reusable totes never hit this target.  Additionally, reusable bags tend to harbor germs.  During the pandemic, many stores banned their use to prevent the spread of COVID-19.

So, there doesn’t appear to be a clear winner among today’s choices of paper, plastic and Continue reading
