DOE’s SuperTruck 3 can help us reach a zero-emission future – if we have the right clean truck standards too

Cleaning up pollution from the U.S. trucking industry is an urgent need for the country. For the past decade, the Department of Energy’s SuperTruck Program has helped showcase solutions for a cleaner future. Now Energy Secretary Jennifer Granholm has announced a new generation of the DOE SuperTruck program – SuperTruck 3 – that will focus on higher efficiency and zero-emission solutions.

Through the SuperTruck 3 program, DOE will provide $162 million in funding to “pioneer electrified medium- and heavy-duty trucks and freight system concepts that achieve even higher efficiency and lower emissions.” The funding focuses on a range of approaches, including all-electric systems, plug-in hybrid systems using renewable biofuels and hydrogen and fuel cell technologies.

Annular pressure monitoring and testing makes for safer wells

There are nearly a million active oil and gas wells in the United States, and if not correctly designed and maintained, they can leak harmful substances that will irreversibly pollute our land, air and water.

A new study published in the Proceedings of the National Academy of Sciences looked at data from over 100,000 wells and estimates that at least 14% experienced some loss of integrity, which could indicate a leak.

The study’s authors were able to determine the functionality and health of these wells based on data collected from annular pressure tests. In fact, the study analyzed almost 500,000 pressure tests conducted across three different basins — one of the largest studies of well integrity conducted to date.

Gearing up for a zero-emission world

President Biden’s sweeping infrastructure package includes $174 billion for electric vehicles, an investment that will speed the transition away from polluting gas and diesel vehicles and toward cleaner forms of road transportation. The upfront cost of infrastructure is a key barrier to rapid deployment of zero-emission vehicles and the health and climate benefits that an electrified vehicle future will provide.

The proposal includes a wide array of vehicle electrification issues — from research and development to manufacturing to increased capability to purchase clean vehicles. But when it comes to maximizing the environmental, health and equity potential of electric transportation, it leaves some critical considerations on the table. Most notably, the potential impact of medium- and heavy-duty vehicles, or trucks and buses.

First and foremost, it is crucial that the country’s investment in zero-emission vehicles includes more than passenger cars and is ambitious in cleaning up all medium- and heavy-duty trucks and buses. President Biden’s call to modernize transit and expand clean school buses is well placed, but the call should extend beyond buses — and as soon as possible. This will require investment in all aspects of the supply chain as well as increased funding and programs to deploy increasing numbers of zero-emission vehicles and charging stations throughout the nation —as well as ensuring that communities of color have the tools needed to benefit from the increased deployment of these vehicles.

4 things every utility, fleet and energy regulator should know about heavy-duty truck charging

The transition to electric heavy-duty trucks is upon us, sparked by a steady decline in battery costs, continuous improvements in electric truck and charging technology, and growing recognition of the climate and local air quality impact of diesel trucks. But even as household names like FedEx, PepsiCo and Amazon have made public pledges to electrify their truck fleets, concerns that charging infrastructure will be able to meet fleets’ needs cost effectively threaten to slow the market-wide transition.

A study commissioned by EDF and conducted by Gladstein, Neandross and Associates addresses these charging questions and provides a pathway to ensuring heavy duty trucks can electrify.

What does it really mean for a gas utility to go net-zero?

SoCalGas – the nation’s largest gas utility recently pledged to go net-zero on their greenhouse gas emissions. At face value, this is a great move, but what does this really mean for a gas-only company that has had some major climate missteps in the past? And what are the implications for current and future SoCalGas customers?

Today, customers use natural gas for a variety of purposes — to warm our homes, to take hot showers, to cook hot meals. But as part of the transition to a cleaner energy economy, more and more customers are shifting to electric appliances to perform those same functions. That shift means that they will be leaving the gas system to a decarbonized electric grid.

That’s great news for the climate, but it’s less great news if you’re a gas-only company or if you’re one of the few gas customers left on the system, especially if you are a large industrial customer and there is not an electric alternative available for your business process.

Careful accounting is critical to assessing the climate benefits of biomethane

By Mark Omara and Joe Rudek

Multiple states are exploring the use of renewable natural gas to decarbonize their gas systems. Renewable natural gas tends to be a generic term that describes a variety of fuels, including hydrogen, synthetic gas and biogas.

As we explained in an earlier blog, not all biogas (a biomethane precursor) is created equal. In order to provide climate benefits, renewable natural gas fuels must result in a net reduction in methane emissions, since methane is a very potent greenhouse gas that is rapidly increasing the rate of near-term global warming. The simple label of “bio” on the methane does not mean that it is automatically renewable or that it provides climate benefits. Both the selection of source of the organic fuels and the injection methods must be done correctly to provide climate benefits.

But what does “done correctly” mean?
