$this->bbcode_second_pass_quote('', 'F')eb 12, 2024 - In the U.K., the government is investing in the assessment of the potential for old coal mine sites to be converted into renewable energy hubs. As many governments around the globe aim to phase out the use of coal, researchers are exploring the potential for old mining sites. Rather than be left abandoned, ex-coal production sites could be used for a multitude of purposes, from solar energy to geothermal operations, supporting a green transition and reinvigorating the economies of previous energy hubs.
In the U.K., the metro mayor for the west of England, Dan Norris, is investing £1.5 million in the exploration of over 100 coal mines in Somerset and South Gloucestershire to explore the potential for supplying renewable heat sources in the region. The mines in this region were emptied of coal and then closed and flooded, as the pumps were turned off. The water in the mines is heated by geothermal energy, with heat coming from the Earth’s core, allowing it to reach temperatures of around 20oC. The idea is that the water is extracted, and the heat is separated from the water to be used in heat pumps in homes and businesses across the country. New geothermal operations in existing coal mines could provide vast amounts of low-carbon heat. In addition, the water is pumped back into the mines to be recycled, making it a highly efficient process.
And it’s not just the geothermal energy potential that researchers are exploring when it comes to repurposing old coal sites. With many coal operations covering vast amounts of land, they are ideal for conversion into solar farms. Installing solar energy infrastructure on degraded lands like mining sites and landfills is a low-cost way of transforming the sites into clean energy hubs. Using ex-mining sites can help save time and costs associated with project development, as many sites already have vital infrastructure, such as transmission lines and roads. It can also revitalise the economy of former energy hubs, creating jobs and providing clean energy for communities.
Daniel Kestner from the Virginia Department of Energy explained, “In the coalfield region, there are about 100,000 acres that’s been impacted from mining… better to build on a lot of these mine sites than some prime farmland or some areas that maybe don’t want solar in their community.”
As governments look to increase their renewable energy capacity and reinvigorate former energy hubs, the repurposing of coal sites could provide the perfect opportunity for transformation. There is huge potential for the development of both geothermal and solar energy operations, which could help bring jobs and revenue back to long-neglected mining communities, as well as support a green transition.
Abandon Coal Mines Are Being Repurposed Into Renewable Energy Hubs$this->bbcode_second_pass_quote('', 'J')anuary 14, 2024 - Across the United States, coal-fired power plants are shutting down for good. In the last twenty years, over 600 have been retired. But just because these plants aren’t burning coal doesn’t mean they aren’t still being used. A trend is now emerging in a number of states to repurpose the plants to create new jobs and supply clean, renewable energy.
So, why would a solar farm, for example, want to be placed at the site of a non-operational coal plant?
It turns out that because these plants are already wired to the power grid — meaning that they’re already connected to the network of substations, transformers, wires, sensors, and poles that carry electricity from power plants to be distributed to our homes — installing new power plants at the site of old ones saves energy companies a lot of money and time.
Additionally, many oppose installing new power lines because they can spoil a nice backyard view, or even reduce your property’s value.
All these factors make existing coal plants ideal sites for new clean energy projects to set up shop. In the race to ramp up clean energy production across the United States, this is an important part of what the future looks like.
The idea to transition these sites has taken hold in a number of states, with Illinois leading the pack. In the Prairie State alone, there are currently nine plants that will become solar farms or battery storage facilities.
And more coastal states like New Jersey and Massachusetts are opting to repurpose their coal plants for new wind farms.
These switches make sense, as clean energy is quickly becoming the least expensive energy source available in many states.
