Since Northwest Arkansas is gaining an estimated 30 people per day, we're providing some insight into Arkansas' election rules — and a refresher for those who've been here a while.

What's happening: The Arkansas primary election to select nominees for the November general election is May 24, with early voting beginning on May 9.

• Residents must register by April 25 to be eligible to vote in the primary.

Why it matters: Primaries typically have low voter turnout, but voting in every election is the best way to make sure your voice is heard on issues you care about.

On the ballot: Candidates for U.S. Senate and the House of Representatives.

• State-level races for governor, lieutenant governor, attorney general, secretary of state, state treasurer, state auditor, commissioner of lands and the Arkansas Supreme Court.
• Various county offices.
• All 100 state representative seats and all 35 senate seats.

The intrigue: The entire senate is up for a vote due to redistricting following the U.S. census.

Catch up quick: Arkansas has an open primary, meaning registered voters can choose to participate in either the Democrat or Republican primary, regardless of which party they're registered with.

• Voters can search for information on candidates by their name or the county where they live.
• A voter can choose a non-partisan ballot, but it only lists judicial or prosecuting attorney candidates and special issues.

But, but, but: If there is a primary runoff, a voter will only be permitted to vote for the same party they voted for in the primary, Daniel Shults, director of the state board of election commissioners, tells Axios.

By the numbers: In 2020, there were 1.8 million registered voters out of just more than 3 million Arkansans. The population number includes those too young to vote.

• Over the past decade, between 20% and 40% of registered voters turned out for primary elections.
• Between 50% and 67% of registered voters typically turn out for general elections.

Walmart has agreed to an option to buy up to 20 tons of green hydrogen from Plug Power — enough to power 9,500 lift trucks — the companies announced Tuesday.

Why it matters: Walmart is using hydrogen fuel at some of its distribution and fulfillment centers, but the agreement marks the first time the retailer will be specifically sourcing green hydrogen, writes Axios' Alan Neuhauser for Axios Pro Climate Deals.

The details: Plug Power will only be able to start supplying the green hydrogen once its plants are up and running.

• Its plant in Georgia is expected to begin producing green hydrogen at the end of this year. Until then, it is providing Walmart with "gray hydrogen" sourced from natural gas and industrial waste.

Catch up quick: Green hydrogen uses renewable energy to power the electrolysis process that separates hydrogen and oxygen atoms. Other colors, such as blue and gray along the "hydrogen rainbow," are less climate-friendly.

Reality check: Producing hydrogen with renewable energy remains relatively costly — last year, it cost about twice as much as other methods.

Of note: Even as Walmart's labor practices continue to attract scrutiny, the company has announced relatively ambitious goals to reduce its emissions, including taking steps to reduce emissions along its supply chain.
