In Part 1 of this series we discussed greenhouse gas emissions, how they are applicable to methane and other energy sources including solar PV and batteries, and why the responsible use of methane must be considered as a viable energy source for the production of electricity.

In Part 2 of this series we will focus on the energy required to create energy.

All Energy Takes Energy to Create Energy!

As we strive for a sustainable and efficient energy future, the choice of fuel source becomes crucial. One component of the equation that must be considered as we plan our energy future is Energy Return On Energy Invested or EROEI.

EROEI assesses how much energy is obtained from an energy source relative to the energy invested in extracting, refining, and using that source. It provides insights into the energy profitability and effectiveness of a particular energy system.

The calculation of EROEI involves considering all the energy inputs throughout the lifecycle of an energy source, including exploration, extraction, transportation, refining, and operation. This encompasses both direct energy inputs, such as fuel used for extraction, and indirect energy inputs, such as the energy used in manufacturing and maintenance of equipment.

A higher EROEI indicates a more energy-efficient and sustainable energy source, as it signifies that more usable energy is obtained compared to the energy invested. Conversely, a lower EROEI suggests that the energy source requires a significant amount of energy input relative to the energy it generates.

EROEI is a valuable tool for assessing the viability, economic feasibility, and environmental impact of different energy sources. It helps inform decision-making processes regarding energy investments, resource management, and the transition to more sustainable energy systems.

As you can imagine, the EROEI varies greatly per power source. The following chart shows average EROEI multiples for various fuels (data from ARC Financial Research (2) – Peter Terzakian “The End of Energy Obesity” (1))

Conclusion

This chart clearly illustrates that methane has a very high return on energy invested compared to energy sources like solar PV or biodiesel. In fact, methane has about three times the return on energy invested than a source like solar PV. This is a significant difference considering the abundance of methane in North America and the well-established methane distribution methods that exist (e.g., pipelines, LNG, CNG, etc.).

When this EROEI is factored into a decision matrix along with the GHG emissions conclusions from Part 1 of this series, one must seriously consider the responsible use of methane as a fuel for energy generation.

What is HVO and Why Should You Care?

As the world seeks to transition to cleaner and more sustainable energy sources, the choice of fuel plays a crucial role in achieving these goals. Hydrotreated Vegetable Oil (HVO) has emerged as a promising alternative to conventional diesel fuel. According to Neste Oil (1) it is “the highest quality diesel in the world.”

How is it Made?

HVO is created from a feedstock of various vegetable oils and animal fats. This feedstock is treated to remove impurities (moisture, particles, etc.). It is then mixed with hydrogen gas and fed through a hydrotreating reactor which creates the HVO fuel. It goes through some additional post-reactor purification steps to remove any remaining impurities like sulfur and nitrogen compounds. For more details you can refer to the Beginners Guide to Hydrotreated Vegetable Oil article here (4).

Why is it Important?

HVO is a “drop-in” ready fuel replacement for many diesel engines. This means that HVO can replace diesel fuel in a diesel engine without any modifications or adjustments to the diesel engine. All of mtu’s diesel engines used in their power generation equipment are HVO ready.

Advantages of HVO

It is a more stable fuel than diesel – Diesel fuel that is stored in a tank for any length of time (e.g., standby power generation) requires periodic fuel scrubbing to remove algae that grows in the fuel. HVO is not susceptible to this issue and remains stable over long periods of time.

Mixes seamlessly with diesel – HVO can be added to existing diesel so existing tanks do not have to be drained prior to topping up with HVO.

Lower greenhouse gas (GHG) emissions – One of the significant advantages of HVO over diesel is its potential for reducing greenhouse gas (GHG) emissions. HVO fuel has a significantly lower carbon footprint compared to conventional diesel. According to studies (2), HVO can achieve up to 90% CO2e (carbon dioxide equivalent) emissions reduction compared to diesel.

Improved air quality – Compared to diesel, HVO offers improved air quality due to its cleaner combustion properties. HVO fuel reduces emissions of harmful pollutants such as particulate matter, nitrogen oxides (NOx), and sulfur oxides (SOx). Dependent on load profiles, a 50% to 80% reduction in particulate matter has been seen.

Improved performance – Switching from diesel to HVO can result in improved engine performance and decreased fuel consumption. In addition to this, when used with mtu diesel engines there is no engine derate (3).

Take Action

If you need more convincing before you make this change, Rio Tinto has recently moved to HVO fuel for their large vehicles in their California open pit boron mine (6). Sinead Kaufman, Chief Executive Rio Tinto Minerals said: “We are proud that our U.S. Borax operations have become the first open pit mine to operate a fleet running entirely on renewable diesel. This is an excellent example of what happens when internal and external partners collaborate toward a carbon reduction goal. Support from the state of California has also been incredibly important, as without their vision, this would not have been possible.”

Take action now for your standby diesel generators and get improved performance, decreased fuel consumption, less emissions, and longer fuel life! Contact Collicutt today and we will work with you to evaluate your generator and arrange for HVO fuel delivery.

California Faces Multiple Increased Risks for Power Outages

June 22, 2022

The state of California is known to be near, if not at the top of the list when it comes to most power outages in the United States. The most common causes of California power outages are related to extreme weather. California is prone to extreme heat, droughts, winds and deadly wildfires and this year is no exception as this extreme weather is predicted to hit California once again.

With that being said, it’s vital that you are prepared for both planned and unplanned power outages. Unfortunately, as most of you know, there are still global supply chain issues, resulting in lead times that are longer than expected. Therefore, if you’re looking to be proactive versus reactive, start planning now. We can help with all your power generation needs!

To assist in your preparation, we have prepared a list of factors to be aware of that could increase the risk of power outages this summer:

Extreme Heat

During the hot summers that California encounters, more people use power to cool down their homes and business; this greatly increases power demand. When this heat is combined with adverse weather conditions that could reduce output from other power sources, system operators may also be forced to use emergency procedures to prevent catastrophic grid failures and extended outages. In addition to that, the extreme heat will cause electrical equipment to fail.

Drought

In relation to California’s hot temperatures, droughts may also increase the risk of a power outage as they can strain the electricity supply. Hydroelectricity is another energy source that California highly depends on and if its reservoirs run low – likely due to extreme heat – there will be a significant drop in hydroelectric generation. With this drop in energy production, the chances of an electricity shortages rises.

Wind

Extreme heat coupled with drought conditions gets exponentially worse when extreme winds come into play. This is what California is faced with every year when the Santa Ana winds start blowing or when the state is hit with the fierce Diablo Winds. Beside knocking out power, these winds can cause power line breakages which will spark wildfires.

Wildfire Season

Summer and early fall in California tend to also be referred to as “wildfire season”. Wildfires are devastating, unpredictable and they move extremely quickly. They can destroy transmission lines and electrical infrastructure which results in power outages that may last days or weeks.

Planned De-Energization Events – Public Safety Power Shutoffs (PSPSs)

PSPSs are a newer, more proactive solution where utility companies shut off power during extreme and dangerous weather conditions to reduce the changes of wildfires breaking out in high-risk areas. Numerous high-risk areas have been identified in California and, for that reason, these events are anything but out of the ordinary for California residents and businesses.

Supply Shortages

As mentioned above, hot California summers can result in low electricity generation. At the same time, electricity demand peaks during periods of extreme heat as, people tend to use their air conditioning all at the same time. Because of this, the grid will be challenged and will struggle to meet the energy demands.

All these factors listed above, substantially increase the risk of power outages. We know that, in today’s world, the majority of industries and businesses rely on electricity to be operational and to provide their goods and services to their customer base. Therefore, these hazards cannot be ignored. We want to ensure that you and your businesses are safe, with the ability to still maximize your uptime. We can support you by maintaining your existing generators, upgrading you to a new generator where it makes sense, or providing backup power generation solutions.
