How Much Energy Could We Harvest From Artificial Photosynthesis?

9
Solar cells use photovoltaic technology to generate electricity, but the process is far from efficient. Plants are much better at converting sunlight into energy. Now, scientists are looking for ways to mimic the process of photosynthesis, which would turn Earth’s most abundant resource into fuel.

How much energy could we acquire by doing what plants do best?

From Sunlight to Sugar

Photosynthesis is the process by which plants take in water, sunlight and carbon dioxide to produce sugar and oxygen. Artificial photosynthesis seeks to produce hydrogen, electricity or alcohol-based fuel. This energy could be immediately stored away for future use.

The ability to transform sunlight into fuel as efficiently as plants do — or better — would revolutionize the energy sector. That’s because as useful as solar panels are, they're only 15%-20% efficient on average. Scientists have developed some panels approaching 50% efficiency, but this is far from the norm.

Plus, photovoltaics still isn’t as efficient as photosynthesis, which captures and stores about 60% of received solar energy in the form of usable fuel. Some scientists even think an 80% target is possible. Given that artificial photosynthesis could potentially quadruple the amount of energy we could harvest, it’s no wonder that scientists have been researching the topic since the 1970s.

How Would It Work?

There are many postulated ways to achieve artificial photosynthesis. They are a form of biomimicry, in which scientists take inspiration from nature to design a product or process. Everyone is turning to plants to understand what makes them so efficient so they can achieve photosynthesis in the lab.

One idea is to create an artificial leaf that takes in light and splits water molecules into hydrogen. The end product would be hydrogen, which is rarely found in its pure elemental form in nature, that could be used as energy. For example, hydrogen-powered ships, buildings and cars could use the fuel.

 In 2011, scientists created an artificial leaf about the size of a playing card that could split water into hydrogen and oxygen. It wasn’t efficient enough to be mass-produced, but it offered a sign of hope in the burgeoning field of artificial photosynthesis. All current artificial leaf technologies rely on pressurized carbon dioxide. The challenge lies in drawing CO2 from the ambient air.

Another idea for artificial photosynthesis is the tarp model. A tarp coated with solar cells could be placed on a flat surface to take in sunlight and water. Technicians could then put it in a tank full of chemical catalysts to turn carbon dioxide into fuel.

Future Directions

Scientists have built rudimentary artificial photosynthesis systems in the past, but the technology needs to be more sophisticated to justify the cost. That’s how most scientific advancements work — it can take decades of speculation and experimentation before creating something viable.

Simultaneously, many people are working on improving solar panels, wind turbines and other renewables to generate more energy. This shouldn’t be seen as competition for the field of artificial photosynthesis. Efforts to reduce climate change take many forms, and every innovation helps.

For example, many countries are now creating floating solar farms on lakes and water treatment plants, maximizing the ability to capture sunlight and hydropower. Biodigesters, which are large tanks full of bacteria-containing fluid, are turning household food waste into methane for cooking in Africa. Several countries even plan to send solar panels into space to constantly absorb sunlight.

Renewable Planet

Regardless of the form it takes, renewable energy is here to stay. Fossil fuels are in limited supply and contributing to climate change, and the world is ready for alternative power sources. Artificial photosynthesis could earn its place among them. It simply needs to put down roots.

They are heartless scammers, they ruined my life, by making me develop interest to invest my hard earned money. I deposited 10.7850 euros in June 2020, which was later turned to 98,908.00 euros including my pay out bonus, there was an impressive improvement in few days, 2 months later I had a car accident and needed money to pay my insurance access, Suddenly I was sent from Pillar to post, i tried reaching out to them to collect the money i invested to pay off my debts, they cut the live chats and got harassed from 1 to the other, until they told me I will forever be poor, then i realized that i was being scammed. I just wanted my money back! I was advised by a friend to seek for help from a recovery management to assist me recover my invested funds, God so kind i was able to reach out to a recovery guru VIA [email protected] or what\'sapp +1 (507) 414-7049, i was able to recover my funds with the help of Mr JAMESMCKAYWIZARD his an expert on crypto/forex and bitcoin recovery, I feel obligated to recommend him and his team, their recovery strategies, and for working relentlessly to help recover my funds. feel free to reach out to him via his email address: [email protected] or what\'sapp +1 (507) 414-7049, and will guide you on how to recover your invested capital, i advise everyone to be careful with this heartless stealing people.

My Name is Karoline from the United States, I want to say thank you to Mr Mark Toray for the good thing he has done for me, Though am not sure if this is the best forum to show my joy and happiness for what he has done for me but i can’t hide my happiness and my joy so i have to share it with people. This is unbelievable, at first I never actually built any interest in this Binary/Forex trading of a thing but when I later gave it a try with the Help of this wonderful Expert Trader Mr Mark Toray, it was a successful trade for me. All i did was to invest $1000 into my first trading and to my greatest surprise, I received a huge amount of $12,520 as profit in 7 days of trading... Mr Mark Toray was the trader that made it possible and he is still doing it all for me.. You want to be happy and be free me do well to reach out to her via Email: [email protected], Telegram: @Mark4toray_fx

Stunning site! Do you have any accommodating clues for trying essayists? I’m wanting to begin my own site soon yet I’m somewhat lost on everything. Would you prompt beginning with a free stage or go for a paid alternative? There are such a large number of alternatives astros blue sequin jacket out there that I’m totally overpowered .. Any thoughts? Welcome it!

I think that your remarks about the efficiency of photosynthesis are grossly flawed (by orders of magnitude) see https://en.wikipedia.org/wiki/Photosynthetic_efficiency
