Solar power more feasible than nuclear to power potential Mars settlements: Study

Solar power could provide all the needed energy for an extended mission to Mars and is more efficient than nuclear energy, according to a new study.

Scientists and engineers at the University of California Berkley said in a statement that the high efficiency, light weight, and flexibility of the latest solar cell technology makes it the most efficient.

Many scientists who have thought of the logistics needed to live on the Red Planet have assumed that nuclear power would be the best alternative, mainly due to its reliability and 24/7 operation.

Over the past decade, miniaturized Kilopower nuclear fission reactors have advanced to the point where NASA considers them to be key to future robotic and human exploration and a safe, efficient, and plentiful source of energy.

However, solar power on the other hand, must be stored for use at night. Nighttime on Mars lasts about the same duration as on the planet Earth. Solar does have its downsides when it comes to this because energy production can be stifled by the red dust that covers the planet.

After a massive dust storm on Mars in 2019, NASA’s nearly 15-year-old Opportunity rover, powered by solar panels, stopped working.

The new study which was published in the journal Frontiers in Astronomy and Space Sciences used an approach which compared the two technologies head-to-head for an extended mission to Mars of 490 days, including six people. The scientists believed that this was the most likely scenario for a mission that reduces the transit time between the two planets and extends time on the surface beyond a 30-day window.

The team’s analysis found that for settlement sites over nearly half the Red Planet’s surface, solar is comparable or better than nuclear when taking into account the weight and efficiency of solar panels. This is feasible so long as daytime energy is used to produce hydrogen gas for use in fuel cells to power the area at night or during sandstorms.

“Photovoltaic energy generation coupled to certain energy storage configurations in molecular hydrogen outperforms nuclear fusion reactors over 50 percent of the planet’s surface, mainly within those regions around the equatorial band, which is in fairly sharp contrast to what has been proposed over and over again in the literature, which is that it will be nuclear power,” said one of two first authors of the paper and bioengineering doctoral student Aaron Berliner.

“This paper takes a global view of what power technologies are available and how we might deploy them, what are the best-use cases for them and where do they come up short,” said co-first author and graduate student in the Department of Chemical and Biomolecular Engineering Anthony Abel.

“If humanity collectively decides that we want to go to Mars, this kind of systems-level approach is necessary to accomplish it safely and minimize cost in a way that’s ethical. We want to have a clear-eyed comparison between options, whether we’re deciding which technologies to use, which locations to go to on Mars, how to go and whom to bring,” he added.

Saudi Fund for Development Provides $100 Million Development Loan for the Rogun Hydropower Project

The Saudi Fund for Development (SFD) Chief Executive Officer, H.E. Sultan Al-Marshad, signed a new development loan agreement with the Minister of Finance of the Republic of Tajikistan, H.E. Kahhorzoda Fayziddin Sattor, through which SFD is contributing $100 million USD to fund the Rogun Hydropower Project, a landmark initiative that will enhance energy,
food, and water security, and foster sustainable development in the country. The signing was attended by the Ambassador of the Kingdom of Saudi Arabia to the Republic of Tajikistan, H.E. Waleed Al-Reshiadan, and the Ambassador of Tajikistan to Saudi Arabia, H.E. Akram Karimi, alongside other officials from both sides. SFD’s development loan will help contribute towards a more sustainable and equitable food and water future for Tajikistan, while driving the country’s energy transition and climate resilience. The project aims to contribute to the national energy security and will help advance sustainable
development in the Republic of Tajikistan, by providing the renewable electricity supply to meet local demand and expand electricity production domestically and regionally, producing 3600 MW of energy. The loan agreement will also finance the construction of a 335-meter-tall dam, which will enhance irrigation capabilities and bolster agricultural activities across the country. Additionally, the project will improve flood protection through the construction of four hydraulic
tunnels for diversion and drainage. It will also provide clean and drinkable water to people through desalination, and help advance socio-economic development, by creating both direct and indirect jobs.
Importantly, this project also supports the realization of the UN Sustainable Development Goals (SDGs); specifically, SDG 2, Zero Hunger, SDG 6, Clean Water and Sanitation, and SDG 7, Affordable and Clean Energy.
On this occasion, the CEO of SFD, H.E. Sultan Al-Marshad, said: “Today’s signing marks a major milestone in our shared journey towards a more sustainable future. With this landmark development loan, SFD is not just supporting Tajikistan’s energy future, but also its sustainable development and the well-being of its people. The Rogun Hydropower Project is a beacon of
hope for a bright future that is powered by clean, renewable energy. It will propel Tajikistan towards environmental stewardship and prosperity.”
