Q & A

What is the main idea behind carbon capture and carbon conversion?

Carbon capture involves extracting CO2 from the atmosphere and storing it, while carbon conversion takes that captured CO2 and turns it into useful products, including sustainable alternatives to fossil fuels.

How does Dimensional Energy plan to address the challenge of aviation decarbonization?

Dimensional Energy aims to create sustainable aviation fuels using CO2 and artificial photosynthesis. Their carbon-neutral jet fuel is one way to reduce the carbon emissions from aviation, a sector that is difficult to electrify with current battery technology.

What role does sunlight play in Dimensional Energy's process?

Dimensional Energy uses concentrated sunlight as an energy source to power their carbon conversion process. This mimics the natural photosynthesis process in plants, using sunlight to convert CO2 into useful energy.

How has the cost of the fuels produced by Dimensional Energy evolved?

The cost of fuels produced by Dimensional Energy has significantly decreased over time. Initial prototypes cost around $60 per gallon, but improvements have dropped the price to $27 per gallon, with the potential to reach $1.60 per gallon at larger scales.

What is the expected outcome for Dimensional Energy's large-scale production by 2024?

By 2024, Dimensional Energy plans to scale its production of carbon-neutral jet fuel to commercial levels, aiming to reduce the cost to nearly $1 per gallon, which would make it cheaper than conventional jet fuel.

How does Dimensional Energy aim to achieve cost parity with fossil fuels?

Dimensional Energy plans to use low-cost, renewable energy sources, like concentrated solar power, and strategically locate their refineries near industrial CO2 sources to lower production costs and bring their fuel prices in line with those of fossil fuels.

What is the circular economy concept, and how does it apply to Dimensional Energy's work?

The circular economy involves producing products that do not end up as waste but can be reused or repurposed. Dimensional Energy applies this by capturing industrial CO2 emissions and turning them into useful products, such as carbon-neutral fuels, thus closing the loop on carbon emissions.

What is the significance of using industrial CO2 sources for fuel production?

By sourcing CO2 from industrial emissions, such as those from concrete, steel production, and power plants, Dimensional Energy reduces the cost of CO2 capture and helps offset the emissions produced by these industries, contributing to the overall decarbonization effort.

How does Dimensional Energy's carbon-neutral jet fuel differ from traditional jet fuel?

Dimensional Energy's carbon-neutral jet fuel is produced by capturing CO2 from the atmosphere and converting it into fuel, making it carbon-neutral. This means the fuel does not contribute additional CO2 to the atmosphere when burned, unlike traditional jet fuel, which releases carbon stored from fossil sources.

Why is Dimensional Energy's approach to fuel production important for combating climate change?

Dimensional Energy's approach is important because it provides a way to decarbonize sectors that are difficult to electrify, like aviation, by creating sustainable fuels from CO2. This helps reduce the reliance on fossil fuels and could play a crucial role in mitigating climate change.
