Storing Energy With Captured CO2
Capturing carbon dioxide instead of releasing it into the atmosphere is a way we can use fossil fuels without it having harmful effects on the climate. Energy storage is a way to address the volatility of clean energy sources like wind and solar power. Excess energy stored during peak production can be used when production ceases, such as when the sun is not shining or the wind is not blowing.
The Largest Battery Storage Substation
At the end of last year, Southern California Edison turned on the largest lithium-ion battery storage facility in the world in Ontario, California. It is a substation with 80 megawatt-hours of capacity, enough energy to power 2,500 households or charge 1,000 Tesla cars a day.
Storing Energy In An Old Mine
An abandoned, centuries-old iron mine in the Adirondacks about 100 miles north of Albany, New York may become the site of a new hydroelectric energy storage system. The mine in the tiny hamlet of Mineville near Moriah, New York contributed iron for the first naval battle of the Revolutionary War that took place on Lake Champlain. The mine hasn’t been used in over 45 years.
Turning Carbon Dioxide Into Rock
There is a lot of interest in figuring out a way to store carbon dioxide produced from industrial processes and energy plants or even sucking it out of the atmosphere and then storing it. The problem is where exactly to put the stuff and how to make sure that it stays there.
The Ocean As A Heat Sink
From 1998 until 2013, scientists observed a slowing in the rate of global mean surface warming. In other words, global temperatures were not rising as quickly as before. This quickly became known as the “global warming hiatus.”
Offshore Wind In Europe
The U.S. has just turned on its first offshore wind farm off the coast of Rhode Island. In the meantime, offshore wind continues to grow by leaps and bounds in Europe. Wind energy in the European Union accounts for 12% of its electricity supply. Until 2011, offshore wind comprised only 5-10% of the newly-installed wind energy capacity; now it about one third of the new installations.
Turning Sunlight into Fuel
When looking at the best ways to meet humanity’s energy needs, there is little doubt that the sun is the ultimate answer. In one hour, the Earth receives enough energy from the sun to meet all of our needs for a year. Despite this fact, the world currently only gets about 1% of its energy directly from the sun.
Small Forests And Climate
Trees are the number one way in which carbon can be removed from the atmosphere and stored in vegetation over the long term. A single tree can absorb CO2 at a rate of 48 pounds per year. Because of this, the carbon footprints of 18 average Americans can be neutralized by one acre of hardwood trees. And it has been found that managed forests accumulate more carbon per acre than unmanaged forests.
