15. Clearing the Air: Dr. Romm on Carbon Offsets vs Real Climate Solutions (1/2) Nov 08, 2023

Welcome to another episode of "Redefining Energy Tech," hosted by Michael Barnard. Today, we have the pleasure of having Dr. Joseph Romm, a Senior Research Fellow at the University of Pennsylvania Center for Science, Sustainability, and the Media. Dr. Romm, with a rich background in physics and public policy, has significantly contributed to our understanding of climate solutions, especially in areas like direct air capture and offsets.
Dr. Romm shared about his journey, recounting his time working closely with Amory Lovins at the Rocky Mountain Institute, and his role as the Deputy Assistant Secretary at the Department of Energy. Post his tenure at the Department, he dedicated himself to climate communication, contributing to the Climate Progress blog until its unfortunate closure. Following this, he took up his current position at the Center under the leadership of Michael Mann, where he is actively involved in research and is in the process of writing three papers focusing on bioenergy carbon capture and storage (BECCS), direct air capture (DAC), and carbon offsets as potential climate solutions.
The discussion started with the concept of carbon offsets, their limitations, and their role in the broader climate change mitigation strategy. Dr. Romm highlighted the concerning trend of organizations opting to pay for projects in places like Brazil or investing in tree planting and deforestation prevention as a means to offset their own emissions. He emphasized the distinction between voluntary market offsets and regulated offsets, pointing out the lack of oversight in the voluntary market which has led to a decrease in price and quality, and the more robust, yet expensive and complex nature of regulated offsets under agreements like the Paris Accord.
The conversation touched upon the 2015 Paris Agreement, its goals, and the challenges in achieving them, specifically addressing the complexities of trading and offsets. They discussed the developments since the agreement, including the introduction of authorized offsets in November 2021, and the concept of corresponding adjustments to prevent double counting of emission reductions. The example of Brazil was highlighted, demonstrating how countries could sell offset credits while maintaining their official emission levels through corresponding adjustments. However, this practice raises concerns about the future, especially for poorer countries that might find themselves at a disadvantage, potentially being pushed out of these markets.
The first half of the discussion concluded with the importance of genuine emission reductions, the challenges associated with offsets and corresponding adjustments, and the need for careful consideration to ensure that the mechanisms in place truly contribute to global emission reduction efforts without exploiting poorer nations.
Read Dr. Romm’s paper on offsets, bioenergy and carbon capture and direct air capture to prepare for COP28. They are available from the University of Pennsylvania.

8. The Quest for a Carbon-Neutral Maritime Future 2/2 Jul 25, 2023

Michael Barnard welcomes back Elisabet Liljeblad, the sustainability and energy lead with Stena Teknik, for the second half of their conversation on redefining energy Tech.
They start by discussing the efficiency of electric drive trains in shipping and compare it to reciprocating engines.
Methanol is explored as a shipping fuel with lower emissions and cleaner burning properties. Ammonia is discussed as a potential transportation fuel but poses toxicity and safety challenges.
Hydrogen is also considered, highlighting its clean combustion but issues with storage, cost, and low conversion efficiency. Equinor abandoned their cryogenic hydrogen bunkering due to high costs. There are doubts about the viability of hydrogen-powered ships, as batteries tend to be cheaper. However, some companies like Swedish Goslin Ferries are still pursuing hydrogen solutions. The challenges of producing and storing liquid hydrogen make it less energy-dense than diesel or ammonia.
A potential solution for ships is a battery-biofuel hybrid model that gradually replaces diesel with biodiesel over time. Electrification using containerized batteries in ports and on ships is another promising option, especially for roll-on/roll-off vessels. Collaboration between the shipping and rail industries could allow shared use of battery containers for more efficient electrification efforts.
Additionally, bunkering electrons instead of conventional fuel is being explored as an alternative for reducing emissions from cruise ships in Norwegian fjords by 2026. Liljeblad discusses the concept of electron bunkering vessels, which are ships with batteries that provide energy to other ships. She emphasizes the need for a total rethink in how we value companies and use resources to address environmental issues.
Liljeblad closes by highlighting the importance of individual responsibility and making sustainable choices as consumers. She believes there is great potential for electrifying container shipping and using existing solutions to transition towards a more sustainable future.

7. The Quest for a Carbon-Neutral Maritime Future 1/2 Jul 07, 2023

Michael Barnard welcomes Elisabet Liljeblad, PhD, the sustainability and energy lead with Stena Teknik, to discuss decarbonization in the maritime industry. Elisabet shares her diverse background including studying the magnetosphere of Mercury and a stint in Afghanistan keeping the peace, and how she ended up in shipping.
Full transcript.
They explore the scale of the maritime industry and its challenge of decarbonization due to its size, variety of vessels, and dependency on fossil fuels. Shipping constitutes a significant amount of emissions globally. The conversation touches upon different types of ships within Stena's business units, including drilling, bulk transportation, passenger ferries, technical services, and their varying operational characteristics. They highlight the need for different fuel logistics as ships transition away from fossil fuels towards electrification or alternative fuels like ammonia, methanol, hydrogen or biodiesel blends. The challenges faced by ports in accommodating these diverse refueling options are also discussed along with onboard carbon capture as a potential solution.The potential for electrification in marine shipping is significant, with projections suggesting that 40% of container ships can be electrified within this decade.
Methanol is another opportunity for shipping fuel, and Stena has converted a ropax vessel to run on both diesel and methanol. Methanol has half the energy density of fossil diesel but doesn't evaporate at room temperature. It's relatively easy to store and handle but requires separate tanks from other fuels due to its characteristics.
Biodiesel, particularly hydrotreated vegetable oil (HVO), burns cleaner than fossil fuels with lower emissions of pollutants like sulfur oxide (SOx) and nitrogen oxide (NOx). HVO is considered a high-quality biofuel that emits fewer harmful substances and doesn't require special considerations like microbial growth.However, as green hydrogen becomes more prevalent in HVO production processes, it may become more expensive compared to other biofuels that don't rely on green hydrogen.
There's no magic bullet solution for decarbonizing marine shipping; it requires a mix of solutions depending on the type of ship and route involved.
They discuss the difference between N20 and NO2, both created by burning anything in our atmosphere, with a focus on their effects on human beings and the environment. Ultimately, the goal is to move away from burning fuels and transition to electric engines as much as possible for more efficient energy utilization.

6. Charging Ahead: Overcoming Infrastructure Challenges in Electrifying Road Freight (2/2) Jun 22, 2023

In the second part of his conversation with David Cebon, head of the Centre for Sustainable Road Freight and professor of mechanical engineering at Cambridge, Michael Barnard discusses the challenges of integrating logistics activity and energy activity in decarbonization efforts. The need for bigger batteries in trucks is temporary and will eventually become a matter of economics.
Transcript.
However, the challenge lies in charging infrastructure at warehouses, where vehicle turnarounds require tens of megawatts to charge during half-hour periods. This distributed problem requires warehouse owners to spend millions on electricity grid connections to charge third-party vehicles. Overhead contact lines are seen as an important solution because they eliminate the need for big fat grid connections and can be built out along heavily trafficked roads through a single contract rather than thousands of distributed warehouses needing upgrades simultaneously worldwide. Modular electric vehicle platforms with battery swapping capabilities could help cover most logistics solutions globally by allowing OEMs to make slightly different configurations depending on country needs while reducing costs compared to adding megawatt hours or hydrogen fuel cells.
Finally, there is a debunked piece of folklore that heavier electric vehicles cause more road damage when truck weight laws vary widely among U.S states with Michigan having double Class 8 tractor semi-trailer weights allowed while civil engineers use something called "the fourth power law" based on outdated constructions from late 1950s AASHO Road Test results which saw most damage occur due to weather conditions rather than vehicle loading factors.Cebon discusses the fourth power law and its impact on road damaging potential of axles, which has been debunked. They also talk about the history of lane width and how it affects driver behavior. Additionally, Cebon shares his opinion on hydrogen fuel cell trucks for heavy ground vehicles and highlights their high cost compared to electric trucks due to a steep learning curve for hydrogen technology in small quantities.

5. Charging Ahead: Overcoming Infrastructure Challenges in Electrifying Road Freight (1/2) Jun 07, 2023

In this episode of Redefining Energy Tech (part 1 of 2), host Michael Barnard interviews David Cebon, director of the Centre for Sustainable Road Freight at the University of Cambridge. They discuss David's expertise in heavy ground transportation and his involvement in the hydrogen science coalition.
Full transcript.
Cebon spent 20 years studying how heavy road vehicles actually impacted roads. That segued a dozen years ago to look into how the segment would decarbonize. Cebon stresses the importance of thinking about the entire day of a truck's journey when considering electrification and the need for a centralized solution to charging infrastructure. It’s not about one segment of the day, but the whole day, end points and availability of charging.
He worked through the implications of batteries, overhead catenary lines and hydrogen, as well as other power options. He’s settled on batteries and overhead lines in suitable high-volume road segments as the right mix for the transition. While battery energy density is clearly going to improve to the point where pure battery solutions for every range and mix of loads will be both viable and dominate, we can’t wait to start decarbonizing the segment.

2. Hydrogen won’t be green if it ignores when, where and how (with Paul Martin) Apr 26, 2023

The Inflation Reduction Act (IRA) along with Canadian, EU and other jurisdictional policies are incentivizing a transition to green hydrogen, albeit in different ways and with often foolish use cases. If governmental money is a thumb on the scale, they should be insuring that the hydrogen actually is green. From that perspective, three terms become important: additionality, temporality and locality. They aren't in the debate for heat pumps or EVs, but are in the debate for hydrogen.
Paul Martin is a co-founder of the Hydrogen Science Coalition and has worked with hydrogen in chemical process engineering design and pilot plants for decades. He’s worked on almost every use case imaginable for the molecule and knows what it’s suitable for. And that isn’t a store or carrier of energy or a pre-cursor of expensive synthetic fuels.
The Coalition’s members thought long and hard about their position on what makes hydrogen actually green as opposed to blackish-blue, and Paul shares his thoughts on the subject. The first principle is that a kilogram of CO2 produced when manufacturing a kilogram of hydrogen, regardless of the process used to get there, is reasonable. The Coalition is agnostic on the process, but that doesn’t mean that they are unrealistic about the costs, quite the opposite. Low-carbon hydrogen will be more expensive hydrogen without significant governmental subsidies like the $3 per kg under the US IRA.
Governmental money should come with strings attached. Those strings are that the low-carbon electricity should be net new generation on the grid (additionality), that production of hydrogen should be matched to the times when the new generation is operating (temporality) and production facilities shouldn’t be on filthy grids where extra electricity will actually be generated by coal or gas with the new renewable generation a thousand kilometers away.
Listen in as Paul and Michael discuss what makes sense, edge conditions and nuances around green hydrogen.

1. Asian heat waves dampen enthusiasm for EU Fit for 55 and US EV tax credits (this episode is also Minutes 63) Apr 23, 2023

As heat waves bake Asia, Gerard, Laurent and Michael discuss the implications. Even at 1.2° Celsius of warming, the impacts are already very significant, and more warming is baked in. But this black cloud comes with silver linings.CATL made significant announcements related to batteries, and in Gerard’s opinion, CATL has earned credibility, so unlike many announcement in the battery space, these don’t need a cubic meter of salt. 500 Watt/hour per kilogram solid-state batteries roll over the delaying tactics of the aviation and trucking industries, and battery differentiation for different use cases is starting to increase.
The EU passed Fit for 55, which includes a carbon border adjustment mechanism. That means that one of the biggest economies and importers in the world is now slapping a carbon price on significant imports from across the Atlantic and China, changing the economics of trade for the cleaner.
Will the USA get there? Likely, but it’s two steps forward, one step back.US EV tax credits provide the maximum of $7,500 only for 14 of 91 models of EVs sold in the country, and only domestic manufacturers made the cut. Early union-made only requirements that excluded Tesla were dropped, so its models qualify. And one of us has finally seen a Rivian in the semi-wild, as it was outside of the Rivian showroom a block from where Michael lives.
