These days, the federal government has mostly turned its back on efforts to mitigate climate change or, for that matter, to even recognize its existence. However,the budget bill passed in February contained a major increase in the tax credit known as 45Q, which provides incentives to businesses to develop and utilize carbon capture, utilization and storage technologies.
Geothermal energy uses the heat trapped beneath the Earth’s surface to generate electricity. Typically, geothermal energy plants tap into the steam from natural sources such as geysers, or they draw water from hot, high-pressure underground sources. The hot vapors are then used to drive electric turbines.
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 Arctic used to be pretty much a pristine wilderness populated only by fairly small numbers of indigenous residents living environmentally benign lifestyles. The disruptive elements of modern civilization were not much of a factor. Because of the changing climate, this is no longer true.
One of the strategies to tackle the problem of increasing greenhouse gas emissions that are resulting in climate change is Carbon Capture and Storage or CCS, which seeks to prevent CO2 from entering the atmosphere and to instead tuck it away somewhere. A longstanding approach to doing it is to store it underground in voids such as abandoned oil and gas reservoirs. There are various complications associated with this idea, not the least of which being potential leakage of the stored CO2.
Plastics are the ubiquitous workhorse material of the modern economy. Their use has increased 20-fold in the past half century, and production of plastics is expected to double again in the next 20 years.
