Oregon On Verge Of Requiring 100% Clean Electricity By 2040

Electric grids do not change overnight. Power plants and other infrastructure are multi-decade investments, and it’s rare to retire them early. So, it’s a bit painful to watch how slowly they have been getting cleaned up. Even with the majority of new power plants being renewable energy power plants, the percentage of electricity coming from renewables only creeps up.

That can make 100% renewable energy or 100% clean electricity commitments seem car too far out, far too slow. A potential new requirement for utilities in the state of Oregon is one such example. If it gets through the state legislature, it will be one of the most aggressive timelines in the United States. However, it still gives the utilities nearly 20 years to fully decarbonize. Yes, 100% clean electricity by 2040 is ambitious when compared to other laws around the States. However, when looking at how much we need to cut emissions by 2040, that should be more of an average or norm than a leadership position. Nonetheless, in political context, it is something to celebrate.

Additionally, the bill as it is currently written requires that electric companies such as Portland General Electric and Pacific Power (the state’s two largest utilities) cut their carbon emissions 80% by 2030. An 80% reduction in emissions from a baseline level in just about a decade is a pretty aggressive transition for this sector. What is the baseline year, you ask? That’s actually not in the legislation. Not seeing it reported, I dug up the bill (Oregon House Bill 2021) and found this instead of a specific starting point: “Requires DEQ to determine each electric company’s baseline emissions level and, for each retail electricity provider, the amount of emissions reduction necessary to meet the established clean energy targets in the state policy.” Knowing how much these kind of things can be corrupted, I’m not thrilled to see a lack of clarity on this. However, I expect the state’s Department of Environmental Quality (DEQ) would be just about the best outfit to come up with the baseline. I hope.

Back to the state’s potential new requirement, reporting out of Oregon indicates that the legislation is likely to be passed this year. “Everyone OPB interviewed for this story suggested the bill is likely to pass this year, marking a significant milestone in Oregon’s energy policy — even if it’s one other states got to first.” It apparently has 100% opposition from Republicans in the state legislature, but Republicans don’t rule the show there. Its likelihood of passing is reportedly high despite a cap-&-trade bill dying last year as Republicans walked out of session early in order to kill it. This new bill is much narrower. Furthermore, it seems to have the support of the electric utility companies (which is something I find indicative of a not particularly aggressive legislative attempt, but I won’t get into all kinds of speculation or insinuation regarding that).

One line that rather annoyed me in the OPB reporting on the story is the following quote from Sunny Radcliffe, director of governmental affairs and energy policy at PGE, regarding getting to 100% clean electricity: “There is a lack of clarity for how we as an industry are going to get the last bits out,” Radcliffe said. “I don’t know anybody in our industry who knows how to get to zero with the technology we have today.”

I don’t know how Radcliffe doesn’t know anyone in the industry who can see how to get to 100% renewable electricity. After all, some places are already there (including places larger than Oregon), and there are these newfangled things called batteries that some people in the industry must have heard of. Also, by the way, a 2015 analysis out of Stanford showing how Oregon could get to 100% renewable electricity was referenced in the OPB article. In fact, I discovered the Oregon news because the lead author of that paper, Mark Z. Jacobson, tweeted out the story.

Anyway, let’s not harp on one quote from an industry player. Yes, we know how Oregon could get to 100% renewable electricity by 2040 — no worries.

There is plenty of good history and context on the Oregon bill over in that OPB article, so I recommend checking it out if you are curious to learn more. It’s one of the best pieces of local journalism I’ve seen on the topic of state renewable energy. The only major thing I’d change is that I’d point out what I just pointed out above. Though, the writer, Dirk VanderHart, did highlight the Stanford study in the article a bit before including that confusing quote from Radcliffe, so let’s just say that VanderHart slipped in the counterpoint preemptively and less offensively than I just did.

The article also points out key areas where the legislative shift from a cap-and-trade bill to this clean-electricity bill is evidence of somewhat deflated ambition. “Even if successful, the proposal only addresses a segment of the state’s carbon dioxide output.

“According to the DEQ, emissions from electricity accounted for 30% of the state’s greenhouse gas emissions in 2019. The entities regulated under HB 2021 are responsible for the vast majority of that, but some providers are left untouched.

“Several dozen small consumer-owned utilities around the state are not impacted by the bill. Nor is Idaho Power, the state’s smallest investor-owned utility, which was removed from HB 2021 after pressing for an exemption and touting its own decarbonization goals.”

I am certainly of the opinion that we need strong legislation to adequately deal with the climate catastrophe we are inviting upon ourselves. Though, in the case of stories like this, I am typically inspired to point out that we can each take individual action with or without such legislation. We can install record-cheap solar power on our roofs (well, some of us can) and we can switch to electric cars. In fact, the largest electric car seller in the country (by far) is also the second largest solar installer in the country and, seemingly, the one offering the cheapest solar, so you can quickly and easily go solar and go electric at the same time via a simple online store. So, whether Sunny Radcliffe knows how the whole state could run on renewables by 2040, Sunny could be driving on sunshine himself within a matter of months if he wanted to.

Weird Alibaba: An inflatable Chinese electric jet ski for $2,000 – What’s the catch?

Weird Alibaba: An inflatable Chinese electric jet ski for ,000 - What's the catch?

As usual for entries in this Awesomely Weird Alibaba Electric Vehicle of the Week column, the fun EVs we dredge up tend to bridge the gap between fun-looking and palm sweat-inducing. Would you take a cheap inflatable electric jet ski out into the bay or off the coast? What if I told you that you had to build it yourself?

That appears to be the case here with this week’s find. It’s an inflatable vessel that is jet ski shaped, though I’m not sure it fulfills all of the requirements to become a jet ski – namely the water jet turbine.

In fact, there’s actually no motor at all. It seems to be just the 3.5 meter (11 ft) boat itself, but at least it comes with a convenient transom in back to mount your own motor.

And in our case, we can slap on an electric outboard to turn this thing into not just a bad idea on water, but a green bad idea on water.

If you really wanted to stay true to the advertising, you could actually get an electrically powered jet ski-style water turbine to add to this boat. Amazon can hook you up with an impressive offering that looks like it would require cutting an inlet hole in the bottom of the boat and an exit somewhere through the rear transom.

Short of building a true jet ski though, I think an overpowered trolling motor will probably suffice. The vendor for the motor linked above seems to propose that is equivalent to 10 hp, which sounds reasonable for a small watercraft like this.

Technically the motor is only rated at 2.2 kW, which is around 3 hp. But we generally find that small electric outboards offer performance of around 3x the rated power of combustion engine outboards due to their much higher torque. It may not rip as fast as the larger gas engine below, but then again maybe it will. Who knows until we find out ourselves?!

You’ll need a whopping 60V of battery for that awesome little electric outboard, which I’m hoping will fit either under the seat or under the “hood” of the jet ski.

I’d actually be pretty interested to get a look under that hood to see what’s going on with that steering wheel. Since the jet ski/inflatable boat seems to be set up for a transom-mounted trolling motor, I don’t know how they expect to tie in steering linkage to something like that.

But my past experience of buying electric boats on Alibaba has taught me to never discount the ingenuity of East Asian engineers building low-cost vehicles that will presumably hold the life of one or more people in their hands.

One thing is for sure: At around $2k, this will definitely be the cheapest new jet ski you could buy, electric or otherwise. Personal watercraft aren’t cheap, and the electric ones carry a significant premium.

But if you’re handy, don’t mind wiring up a motor and battery yourself, and also don’t mind a steering wheel for show while you twist around to control a tiller motor, then you just might wind up with one of the most unique vessels on your local lake or river.

And consider the ease of transport! You probably don’t even need a trailer like you would for a traditional jet ski. The entire thing weighs just 176 kg (388 lb), though the spec sheet also says it is made from fiberglass, so perhaps the data isn’t quite accurate. Either way, this inflatable vessel can’t weigh too much. And the fact that you can deflate it to fit in the back of a van or SUV is a big benefit too. Or you can just leave it inflated and probably fit it in a truck with the tail gate down. Not my mini-truck, but maybe your truck.

At $2,025 for this thing, it’s pretty darn cheap – though that’s before the cost of batteries and a motor. Don’t forget though that there’d be several thousand dollars in shipping costs, customs import charges, taxes, broker fees, etc. Also, don’t forget that you should absolutely not buy this thing. While I’ve picked up some cool and weird little EVs from Alibaba over the years, it’s never a good idea. The process is long and complicated, not to mention fraught with extra charges at every step of the way. And you never know if the company who just received your wire transfer is even going to deliver your product in the end, which is just another fun little stressor that comes with shopping on Alibaba. So please, don’t join the ranks of my foolish readers and risk your hard earned money on something weird like this.

But if you ignore my warnings and decide to go for it, be sure to let me know what happened! And maybe update your will before the maiden voyage.

Here are the best April Fool's jokes from the e-bike industry this year

April Fool’s Day, celebrated annually on the first of April, is usually a light-hearted and mischievous occasion marked by good-natured pranks, hoaxes, and jokes. Large organizations often take part in hoodwinking others, creating an atmosphere of amusement and (hopefully) harmless trickery. Sure, it’s annoying when you fall for it. But it’s also humorous to see what companies can come up with next. E-bike companies and the larger micromobility industry often have fun getting in touch with their inner prankster (remember the pedal-powered popemobile?!), and this year was no exception. These are some of the fun and light-hearted new announcements from around the electric biking and micromobility world.

We’ll keep updating as we find more, and feel free to send me any you find today (contact info in my author blurb below the article).

Magnum’s human-powered bike

Here in the e-bike industry we are often so deeply focused on the latest batteries or the most innovative new motors that we can sometimes forget our roots. Magnum Bikes, a popular electric bike company, wants to make sure we all remember where we came from with the “launch” of its new human-powered electric bike.

Called the Navigator Infinite, Magnum says the bike can get over 100 miles (160 km) of range. I guess “infinite” truly is at least 100!

Scientists have found major storage capacity in water-based batteries

Texas A&M University scientists have been working with metal-free, water-based battery electrodes, and they’re finding that the difference in energy storage capacity is as much as 1,000%.

How the water-based batteries work

In the scientists’ paper, published in Nature Materials this week, the water-based, or aqueous, batteries consist of a cathode – the negatively charged electrode; an anode – the positively charged electrode; and an electrolyte, like traditional batteries. But in this water-based battery, the cathodes and anodes are polymers that can store energy, and the electrolyte is water mixed with organic salts.

The electrolyte transfers the ions – the charge-carrying particles – back and forth between the cathode and the anode, and the electrolyte is also key to energy storage through its interactions with the electrode.

Chemical engineering professor and co-author Dr. Jodie Lutkenhaus asserts:

If an electrode swells too much during cycling, then it can’t conduct electrons very well, and you lose all the performance.

I believe there is a 1,000% difference in energy storage capacity, depending on the electrolyte choice because of swelling effects.

According to their paper, the electrodes – the “redox-active non-conjugated radical polymers” – are promising candidates for water-based batteries because of the polymers’ high discharge voltage and fast redox kinetics.

However, the researchers note in their paper’s abstract:

[L]ittle is known regarding the energy storage mechanism of these polymers in an aqueous environment. The reaction itself is complex and difficult to resolve because of the simultaneous transfer of electrons, ions, and water molecules.

The future of aqueous batteries

The researchers suggest that water-based batteries might be able to mitigate potential shortages of metals such as cobalt and lithium, as well as eliminate the potential for battery fires.

Lutkenhaus continued:

There would be no battery fires anymore because it’s water-based.

In the future, if materials shortages are projected, the price of lithium-ion batteries will go way up. If we have this alternative battery, we can turn to this chemistry, where the supply is much more stable because we can manufacture them here in the United States and materials to make them are here.

The researchers also conducted computational simulation and analysis, and they’ll carry out further simulations to better understand the theory.

Chemistry assistant professor and co-author Dr. Daniel Tabor said:

With this new energy storage technology, this is a push forward to lithium-free batteries. We have a better molecular level picture of what makes some battery electrodes work better than others, and this gives us strong evidence of where to go forward in materials design.
