Solar Startups & The Production of Concentrated Solar Power (CSP)

The demand for energy is increasing every year, and green energy production is more critical than ever before. The DOE is funding research into supercritical carbon dioxide (sCO2), a key driver for super-efficient solar energy. Solar startups are taking up the challenge and finding innovative ways to make concentrated solar power (CSP).

What is supercritical carbon dioxide (sCO2)?

Supercritical carbon dioxide (sCO2) is a state in which carbon dioxide is a fluid and held at or above its critical temperature and pressure.

That sounds complicated, and it is, but the uses and benefits are significant. sC02 is particularly advantageous in closed-loop power generation whereby it replaces traditional air and steam technology.

In replacing proven technology, higher temperatures can be created at less cost and greater efficiency. This is leading to highly efficient, environmentally friendly, and cost-efficient power generation methods. The energy produced is in high demand across the united states bringing down costs and lowering carbon footprints.

Green Investment

Green investment always has something morally and ethically good about it. With funding from the DOE up for grabs, it is now causing some excitement among startups.

Of course, there are many big and established businesses in the pot, but startups are the companies to watch. Inside these small-medium enterprises sits a wealth of knowledge and levels of innovation that always excite. Finding ways to solve the green energy problem and reducing carbon footprints is high on everyone’s agenda.

With sC02 being a key driver for CSP, many exciting developments are happening throughout the US


Reducing the need for fossil fuels in the production of energy is the sole objective of Heliogen. Founded in 2013 by Bill Gross. Heliogen has received over $39 million in funding to produce and manage a solar-powered supercritical carbon dioxide power cycle.

The technology uses no fossil fuels and is part of a larger heliostat field. Using sCO2, which is twice as dense as steam, electricity is produced with far greater efficiency. This is considered one of the most advanced and innovative energy production methods paving the way for more affordable, green electricity.

Aerojet Rocketdyne

The variety of companies securing DOE funding for research into sC02 is diverse. Aerojet Rocketdyne is primarily focused on aerospace but, in partnership with Southwest Research Institute, is developing air control components.

Having received a total of $6.8 million ($3.6m DOE), it is clear there are a diversity of players coming together to achieve a joint goal. Businesses of all sizes working together bring innovative thinking to the table. Aerojet is just that,
