  • Biodiesel: A Sustainable Alternative for Greener Motoring

    ·

    Brandon Rogers

    One of the exciting possibilities for greener motoring and better sustainability is the use of biodiesel. Biodiesel is technically a biofuel, but (obviously) it’s used in diesel engines, and it’s different from other types of biofuel, such as ethanol.

    But what is biodiesel, how sustainable is it, and is it an option for you as you try to be more sustainable in your transport choices? Let’s have a closer look.

    What Is Biodiesel?

    Biodiesel is more or less like regular fossil fuel diesel. You’d have to be a chemist to tell the difference. In fact, biodiesel is older than fossil fuel, as the original diesel engine invented by Rudolf Diesel himself could run on peanut oil-based fuel and mineral oil fuel. Herr Diesel also thought that plant-based fuels would be the best way to go– too bad that nobody listened to him until recently.

    Biodiesel is different from fossil diesel because it has been made in a laboratory from other oil sources rather than oil that has come up from deep in the Earth’s surface. These sources can be plants (both the sorts familiar from the oil section in your supermarket and some others), animals or algae.

    Where Does Biodiesel Come From?

    Biodiesel is produced from oils, so the real question is where the oils come from. The good news is that a number of oil sources are out there. The bad news, however, is that all of them are slightly different chemically, so some manufacturers need more clarity about how different types will perform in their engines. These sources are known as feedstocks.

    Biodiesel is sometimes made from oils harvested from plants (and algae) grown specifically for the purpose. It can also be made from various types of waste fat and oil. Some of the best-known purpose-grown feedstocks are the following:

    • Soybean oil
    • Canola (rapeseed) oil and the very similar colza oil
    • Coconut oil
    • · Palm oil (not the best from a sustainability perspective)
    • Castor oil
    • Corn oil
    • Sunflower oil
    • Rice bran oil
    • Safflower oil

    The big issue with these purpose-grown feedstocks is that they compete with other crops for land and water. This is a problem, as we need to feed the world (but not overfeed it, so perhaps that’s a way to reach a compromise). You’ve probably also noticed that most of those oils mentioned above are edible to people, so there’s direct competition between food and fuel. However, some crops can be grown on land that isn’t used for much else and doesn’t require the same inputs. These include:

    • Jatropha oil
    • Jojoba oil (yes, the one that gets used in cosmetics)
    • Copaiba oil (this one comes from Brazil and is widely used over there as a biofuel)

    Another exciting feedstock is algae. Several species of algae produce oils that are suitable to be made into biodiesel. Moreover, these algae grow very readily in wastewater, including sewage. This means that they don’t compete with food crops (and other human needs) for freshwater, which is a real plus in terms of sustainability.

    However, the problem of the conflict between food and fuel for inputs can be solved creatively. There are abundant waste oil sources in the food production industry and the restaurant trade. This waste fat, oil and tallow is acceptable for use as a biodiesel feedstock. This means that something that would previously have gone to waste can now be put to productive use. For example, meat processing involves much of the fat being trimmed off before it goes to the market or is processed further because we don’t want to eat it. It’s now being collected to be made into biodiesel. What’s more, when omega-3 oils are extracted from fish oil, the bits that aren’t omega-3 can be used for making biodiesel.

    The same thing happens with waste oil from the restaurant trade. Waste oil from frying is fine for making it into biodiesel (if you take the scrumps and chip bits out first). Plenty of schemes are already in place in the UK for collecting waste cooking fat and oil.

    What Vehicles Can Use Biodiesel?

    Obviously, if your car is petrol-powered, you can’t use biodiesel (look at bioethanol blends instead). However, if you usually fill your car’s tank with diesel, you can fill it with a biodiesel blend. The biodiesel blends are described with the B system, where B stands for biodiesel, and the number stands for the percentage of biodiesel in the mix. Thus, pure biodiesel is called B100, but B5 contains only 5%. All diesel vehicles can handle B5, and most will handle B7. However, when it comes to other blends, a specially designed engine is usually needed to handle the different chemical properties of biodiesel. Check with your vehicle manufacturer about what blend can be used in your particular make and model –. Still, it’s good to know that quite a few vehicles have been specifically made to take biodiesel, including some Fords, Jaguars and Range Rovers.

    It’s also possible to modify an existing diesel engine to take biodiesel without voiding your vehicle’s warranty; however, ask questions before investing in this.

    It doesn’t play nicely with older cars with rubber fuel hoses, as the biodiesel will erode quickly. However, in any vehicle manufactured after the early 1990s, this isn’t a problem, as rubber hoses were discontinued after this time. If you have an old classic and have already replaced the rubber hoses, etc., it will run fine on a biodiesel blend.

    Trains and other large diesel engines can also use biodiesel.

    How Green Is Biodiesel?

    When choosing any form of transportation, it’s worth considering exactly how sustainable it is. A perfectly efficient and sustainable solution is out there to help us get from A to B, carrying everything we need. Still, at the moment, everything has its upsides and downsides. This is true of biodiesel, just like everything else.

    In the time-honoured fashion, let’s get the bad news out of the way first. The downsides of biodiesel are as follows:

    • Some of the oil used for making biodiesel comes from food sources such as corn, which means that fuel crops have to compete with food crops for water, land, energy inputs, pesticides, fertiliser, etc.
    • Most of the existing diesel-powered fleet can’t run pure biodiesel (B100), so using biodiesel in an unmodified car still requires some fossil fuels in the mixture.
    • Biodiesel gets thicker at lower temperatures, so engines don’t work correctly when things get chilly (as in some parts of the USA and Canada).
    • ·If you’re a vegan, you may disapprove of where some fats and oils come from to produce the biodiesel, as animal fats from the food processing industry and the hospitality trade are often used.
    • Biodiesel produces the same pollutants and particulate matter as regular diesel. However, remember that any carbon dioxide released to the atmosphere from the biodiesel (not the fossil fuels) isn’t adding new carbon, as the CO2 in any biological source was in the atmosphere some time ago (maybe about a year in the case of biodiesel that came from fat from a cattle beast that consumed calories from a plant that took in CO2… you get the picture).
    • Biodiesel can be contaminated easily with water, so you have to be careful with it so you don’t end up eroding your car engine.

    However, biodiesel has a number of advantages in terms of sustainability.

    • Every little bit counts! Even if you use 5% biodiesel (B5), possibly in a regular diesel car, that’s 5% less fossil fuel.
    • Because a B5 biodiesel blend can be used in a regular diesel vehicle, it’s easy to make the switch and become more sustainable. Some can use B7.
    • Biodiesel is often made from waste fats and oils from the food industry and restaurants, which solves another problem.
    • Biodiesel can also be made from algae that thrive on sewage, turning another waste product into a resource.
    • Biodiesel uses the same distribution network and facilities (e.g., pumps and tanks) as fossil diesel, so the infrastructure for making the switch is already in place.
    • Biodiesel has better lubricating properties, so it’s suitable for your car’s engine.

    In the quest for greener alternatives, biodiesel emerges as a promising solution. While it has its challenges, the benefits it offers, especially in terms of sustainability, are undeniable. From utilising waste products to reducing our reliance on fossil fuels, biodiesel is paving the way for a more eco-friendly future in transportation. As we continue to innovate and adapt, it’s essential to stay informed and make choices that benefit both us and our planet. Whether you’re considering biodiesel for your vehicle or just curious about its potential, it’s clear that this biofuel has a significant role to play in shaping a sustainable future.

  • Powering the Future: Understanding Sustainable Electricity Generation Methods

    ·

    Brandon Rogers

    Renewable Energy is the Future

    The present era is the Electrical Age with some justification. Nearly everything in our homes runs on electricity, from our phones to our ovens – and just about everything else. Many of us also opt for electric vehicles as a way of motoring more sustainably.

    However, we must stop and think about where that electricity comes from. Sure, using an electrical device doesn’t release any CO2 into the atmosphere, so from that perspective, electricity is clean. All the same, to be really environmentally friendly, we need to think about where our electricity comes from.

    We’re so used to being able to press a button for electricity to flow that we often don’t think much about how it’s generated. In most cases, electricity is generated by turning motion energy into electrical energy (electrical potential energy like a battery). The process involves coils of wire and magnets. Some exceptions exist to this general process of turning motion energy into electricity. One is through chemical reactions, which is what happens in batteries. The other – solar power – is more complicated, as it turns light energy into electricity through a mixture of chemistry and physics. More on solar power below!

    Anyway, with most energy generation methods, the trick is finding a source of motion energy. The classic way of doing this is with steam power (very Victorian). Water is heated to boiling point, and the steam builds up pressure. This high-pressure steam can escape into the mechanism that turns the electrical generator. Most old-school electrical plants use fossil fuels such as coal or natural gas to heat the water, which isn’t sustainable because these fuels aren’t renewable, and they add more carbon to the atmosphere. This is why many people have considered renewable energy sources for producing electricity.

    Photovoltaic Panels

    Photovoltaic panels are the most visible and exciting form of renewable energy. Unlike a typical battery, which wears out through corrosion over time (yes, even a rechargeable battery), photovoltaic panels or solar panels last a lot longer. Even in the UK, we get a fair amount of sunshine. As we all learned in high school, light is a form of energy, and a photovoltaic panel or PV panel can transform this energy into another form. The way that PV panels do this is rather complicated and involves quantum physics (yes, really!).

    Solar energy is so exciting because the sun puts out so much energy – and we’re not making the most of it. Plants use some of the energy of sunlight for growing, and many of us make the most of the natural light and warmth of sunshine, but that barely scratches the surface of what’s available. As we all know, the sun comes up every morning – even on a rainy day. This means that even on a grey day, a solar panel will be able to generate some electricity, although it will certainly create more on a sunny day.

    Producing solar panels consumes a lot of energy in its own right, and some ways of manufacturing them are more sustainable and environmentally friendly than others. However, scientists are working on improving solar cells and solar panels to make them more efficient and to make the process of making them more sustainable.

    One of the beauties of solar power is that you can start small at home – a solar-powered security light or fairy lights, for example. Or you can invest in a solar panel for your home that works with your mains electricity. The only snag is that solar power isn’t available at night, when we use electricity the most in our homes, so a battery is needed as part of the system.

    Hydro Power

    If we turn to the mechanical methods of generating electricity, hydropower or water power is one of the oldest. Waterwheels have been known to humanity for a long time, and the idea of using the force of water to power a mechanism is very old. When people started getting excited about this newfangled electricity stuff back in the Industrial Revolution or thereabouts, water power was one of the earlier methods tried.

    The principle is simple: the water flows, preferably the faster, the better. This water turns the generator and keeps going, so nothing is used up, making this a sustainable way to generate electricity. The tricky bit with hydropower is ensuring a constant supply of water – after all, some years, it rains more than others. A constant supply is usually achieved by building a dam to store the water and then releasing the water as needed. This requires suitable terrain, and some land will end up underwater. However, once a dam is in place, it will last very long and ensure an ongoing electricity supply.

    Wind Power

    Wind generators are other obvious ways to generate electricity. The wind blows and turns the turbo fans, which power the generators as they spin around. These generators can range in size from the massive ones you see in wind farms like Dogger Bank to smaller ones – I’ve seen some in supermarket parking areas that look no more out of place than streetlights.

    Wind power isn’t something that everybody can do at home, as they can only be installed in places that get a lot of wind (obviously!), and they need to be fixed very securely, as they can be vulnerable to being damaged by the winds that power them. However, if you live in a windy part of the country and have a suitable place in the garden or on your roof, you can install a domestic wind turbine. They are a little bit noisy, but not as loud as a car rumbling past, and once you get used to it, the sound is quite soothing. Some people worry that wind turbines can hurt birds. This can happen, but you don’t see as many dead birds under turbines as you do on the road, so the problem isn’t that big!

    Wind power is a sustainable energy solution, as we’ll never run out of wind. However, the weather is always fickle, and sometimes we get more wind than others. This means that wind power isn’t completely reliable and has to be backed up by another source. All the same, it should definitely be in the mix.

    Tidal Power

    Twice a day, the tide goes in and out again – quite dramatically in the Severn! This involves flowing water, and the idea of harnessing the motion energy of water is very old. However, tidal energy still isn’t as advanced as other forms of energy. This is because anything system set up to capture the tide’s energy has not to make life difficult for marine life and boating – and it has to stand up to the corrosive properties of salt water. The issue with marine life is vast, as fish often follow the tides to feed and get killed by the turbine blades. However, tidal power can be used, and they hope to install a lot more.

    Waste To Energy Schemes

    This is the least sustainable option, as it involves burning rubbish to heat water to generate steam to turn a turbine. However, it’s a lot more sustainable than using fossil fuels. Sadly, we generate too much rubbish, and not all of it is recyclable. Rather than sending it to the landfill, it can be collected and burned in a modern facility that captures as much carbon and other emissions as possible so they don’t pollute the air. This means that the problems of plastics in the environment and good productive land consumed by landfills are avoided. It would be nice to think that one day, we won’t produce as much waste, but given the way things are today, waste-to-energy schemes are an excellent way to make the best of a bad job and turn something that is a problem into a solution. In the future, when we don’t throw away as much junk (bring it on!), waste-to-energy plants can still be used but fuelled by plant biomass.

  • Biofuels vs Agriculture – The Clash That Should Not Be

    ·

    Brandon Rogers

    If you follow the discourse on clean energy, biofuels, and the future of the automotive industry, you must have heard the troubling dispute that growing plants for biofuel production takes up valuable arable land. It only aggravates the food supply problems worldwide for questionable energy output.

    How much land does UK biofuel production take?

    According to the official governmental statistics for 2020, available at https://www.gov.uk/government/statistics/area-of-crops-grown-for-bioenergy-in-england-and-the-uk-2008-2020/section-1-biofuels, the percentage of UK total arable area, used for biofuel production, is just 0.6%. Therefore the implied argument that biofuels take up space that can otherwise be planted with corn, vegetables or potatoes (or any other crop, for that matter) isn’t true. Moreover, large portions of biofuel production belong to recycling wasteful products like used cooking oil or tallow, which brings us to the next point.

    What kind of biofuel are we going to produce in the UK?

    We have two options:

    1. Plant-based biofuels. They will always face the media storm mentioned above and attract unnecessary attention. People have to understand, though, that we do not have a problem with food shortages – we have a problem with food waste and unequal redistribution between the Western and Third World (especially areas like Africa and Southeast Asia).
    2. Recycle-based biofuels. Instead of pouring thousands of tons of waste oils down the sewers, we can put them to double use by turning them into fuel. Thus we will not only protect the environment but avoid water pollution at the same time.
