CCRES: Carbon capture and consumption

CCRES: Carbon capture and consumption | Sustainable Technologies | Scoop.it

Could it Eliminate the Need for Wastewater Aeration? Algal blooms have always proved a challenge for the water industry. Yet could this organic matter,with the help of wastewater nutrients, be turned into a biofuel and help alleviate fossil fuel shortages? Tom Freyberg investigates the European funded All-Gas project. First generation biofuels from crops never really bloomed into a fruitful harvest. Opponents criticized using up valuable land to grow crops and fuel the cars of the rich, instead of filling the stomachs of the poor. Second generation biofuels – made from biomass - have proved a lot harder to extract the required fuel and fully crack. And then along came algae. Unlike first generation biofuels, algae can be grown using land and water not suitable for plant and food production. Consuming solar energy and reproducing itself, algae generates a type of oil that has a similar molecular structure to petroleum products produced today. As if this wasn't enough – algae growth also consumes carbon dioxide, a known major greenhouse gas (GHG). As a result of the apparent benefits the race is on to commercialize second and now third generation biofuels, in the case of algae. Continents and companies are putting money where their mouths are to find out how what we thought was simply a green weed growing in the sea could be the answer to inevitable fossil fuel shortages.

Digital Sustainability's curator insight, February 25, 6:15 AM

Researchers from the University of Pennsylvania and Drexel University have demonstrated a new material that can both capture photons from visible light and get current to flow, paving the way for cheaper, more efficient solar PV cells.

Conventional solar panels are based around the interface of two materials: one which absorbs light and excites electrons, and one which causes them to flow in a consistent direction, producing an electric current. The interface which the excited electrons pass through is called the semiconductor p-n junction. Once an electron has crossed over, it cannot return the other way, thus creating the necessary flow.

However, some of the energy from photons is lost while electrons wait to make the jump through the junction. There’s even a name for the maximum theoretical efficiency of cells that use p-n junctions: the Shockley-Queisser limit. Multi-junction cells are able to overcome it, but this increases the complexity of the solar cell structure, which has a knock-on effect for production costs.

A small category of materials are able to send electrons off in a particular direction independently, without a junction; this is known as the ‘bulk’ photovoltaic effect rather than ‘interface’. The phenomenon has been known about since the 1970s but has previously only been shown to work with UV light. As most of the energy from the sun is in the visible and infrared spectrum, it hasn’t therefore been utilised for conventional solar cells.

A new material compound has been shown to generate the flow of electrons without a junction across a much wider spectrum of light. The compound created by the US researchers is a combination of a ‘parent’ material, potassium niobate, that lends it a bulk photovoltaic effect and a secondary one, barium nickel niobate, that lowers the threshold at which photons are absorbed, allowing it to capture more rays. The two materials are ground into fine powders, mixed and heated in an oven to create a ‘perovskite’ crystal that has the properties of both. The researchers fine-tuned the ratios involved until they hit upon the ideal combination.

“A solar cell based on the discovery could double power conversion efficiencies possible with conventional solar cells, theoretically”, says Professor Andrew Rappe at the University of Pennsylvania. It could also help to reduce the amount of materials used in a solar cell, and as perovskites are easier to process than silicon, make them more cost-effective too. The next step, Rappe says, is to create a full-scale solar cell that uses the modified perovskite, which should happen within two years.

Four Innovative Green Technologies That Just Might Save The World

Four Innovative Green Technologies That Just Might Save The World | Sustainable Technologies | Scoop.it

With many developing nations rapidly industrialising, dependent on fossil fuels as their energy mainstay, CO2 concentrations show no signs of abating. What will the ramifications be for food production and health moving forward in to the 21st century if weather patterns become even more hostile than the previous decade?

 

Fortunately, scientists and engineers are working on ways to neutralise emissions in to, or actively reduce the carbon content of the atmosphere until the time arises when we can transition to cleaner energy solutions. In the interim phase we find ourselves however, there are no perfect solutions, but there are technologies and techniques that can help combat the climate catastrophe that will be unleashed if CO2 concentrations continue to rise unchecked. Here a four such technologies…
