This episode is brought to you by Skillshare.  Given the relatively short lifespan, overheating,  and battery cell supply issues of current battery   technologies, they can't be used everywhere. Take  satellites, high-altitude drones, healthcare,   or even spacecraft, all of which require  energy storage with a very long life. But   some companies are claiming that diamond battery  technology can kill two birds with one stone:   creating energy storage that could last for  thousands of years by putting nuclear waste   to use... potentially powering everything  from EVs to cellphones. Is this the holy   grail of battery technology or hype;  and more importantly, is it safe?   Let's explore Nano Diamond Batteries  and where this might be going. I'm Matt Ferrell. Welcome to Undecided. Modern life relies on mobile  battery-powered devices: at work,   at home, at school, and while traveling.  We need batteries for communication,   transportation, storing energy from renewables  like solar and wind, you name it ... and it's   undeniable that lithium-ion batteries  have opened up a world of possibilities. Even though we've seen significant progress with  the lithium technology over the past few decades,   challenges such as overheating, expensive casings,  short lifespan, and underperformance in extreme   temperatures still need to be overcome. So the  quest for the holy grail of batteries continues. Aiming to reach carbon neutrality in the  next few decades, batteries and renewable   power sources need to evolve alongside each  other to solve this puzzle. The International   Renewable Energy Agency (IRENA) estimates that  stationary battery storage will grow from only   2 gigawatts (GW) worldwide in 2017 to around  175 GW in 2030. But batteries aren't the only   way to compensate for the intermittent operation  of solar and wind. We also have nuclear power. Nuclear accounted for 10.3% of the  world’s electricity generation in 2019.   It’s widely considered to be a stable,  carbon-friendly energy source that can be used   to support the intermittency of other renewables.  But besides being expensive and having long   construction times, the unresolved problem of what  to do with long-lived radioactive waste is crucial   for its development. There's a lot of "not in my  backyard" to that debate. If you're interested,   I have an episode on Small Modular Reactors that  gets into the future of nuclear power. As of   today in the U.S., there are 96 commercial nuclear  power reactors currently operating, and more than   90,000 metric tons of highly radioactive nuclear  waste, including spent fuel and other material. Pulling together the challenges  of conventional batteries and the   problems derived from nuclear waste,  a new technology called Nano Diamond   Battery Technology is being touted  as an energy-disruptive innovation. NDB, a California-based start-up  made headlines when it announced   that it completed two proof-of-concept  tests of its nano diamond battery,   made from nuclear waste encased in artificial  diamond. But the root of this energy storage   technology is known as betavolatics, which is  powered by beta decay and goes back to the 1950s. In 1953, Paul Rappaport proposed the use of  semiconductor materials to turn the energy   from beta decay into electricity. Unlike common  electricity-generation technologies that utilize   hydro or wind turbines to spin copper coils  within magnets to produce an electric current,   betavoltaic devices can generate current  when placed close to a radioactive source. Imagine placing a semiconductor material,  like Silicon, in a box with Strontium-90,   which is a radioisotope produced from nuclear  fission. It has a half-life of almost 30 years.   A semiconductor material, like Silicon, can both  act as an isolator or conductor depending on the   conditions it's subjected to, like temperature,  light, or electric current. It's actually very   similar to how solar cells work when collecting  solar radiation. In this case, the radioactive   element emits beta particles that separate  electron and hole pairs in the semiconductor   (holes collect on the positive side and  electrons collect on the negative side).   Bridging the two sides allows the  electrons and holes to find each   other resulting in an electric current ... in  short, this turns radiation into electricity. Using this principle, in 2016, researchers  from the University of Bristol unveiled the   world’s first known diamond nuclear battery,  which is based on this betavoltaic concept.   Tom Scott, Professor in Materials at  the University of Bristol, described   the advantages as the emission free, long-term  production of clean energy from nuclear waste. A great portion of nuclear waste is graphite,  which is used as a moderator and reflector in a   nuclear reactor. The graphite becomes radioactive  over time because of its exposure to radiation.   And depending on the reactor type, the graphite  blocks can be extremely large and heavy,   as well as irradiated with  long-lived radioisotopes,   which makes graphite expensive and  tricky to dispose of or recycle. The reason why graphite is important  here is that radioactive graphite   contains Carbon-14 (C-14), which turns into  harmless Nitrogen-14, an anti-neutrino,   and an energetic electron -- aka a  beta-decay electron. But that's already   TMI ... I'm not going to turn this into  a chemistry class. I'd probably flunk it. The idea behind the research from the University  of Bristol is to manufacture batteries that can   harness this by-product of C-14 as energy.  In its gas form at low pressure and elevated   temperatures, you can convert it into a  radioactive diamond. Then for safety you   encapsulate it again in a non-radioactive diamond  layer. So it's a radioactive diamond ... in a   diamond. Even though the researchers say that  only a small level of radioactivity is detected   near their diamond, would you really want to use  a nuclear powered pacemaker inside your body?   Actually ... there were Plutonium powered  pacemakers, but that's a different video. Even though we typically equate nuclear power  to great amounts of energy being produced,   these betavoltaic batteries can only  generate power in the range of microwatts,   which is why headlines and press releases  about NDB batteries have been overselling it.   This is not the future of electric vehicles.  If their breakthrough proves to be true,   it has some potential ...  for very targeted scenarios.   The difference between the batteries from Bristol  to NDB's is in the layers of the encasing diamond.   While the researchers of Bristol used only a  diamond layer to protect the radioactive diamond,   NDB combines multiple layers of paneled  nano diamonds to protect the core.   These micro-sized single crystal diamonds are very  good at conducting heat, so they move heat away   from the radioactive isotope materials so quickly  that the transaction generates electricity. There are several concepts to ensure safety,  but there's still a lot of questions around   this since we haven't seen any test results  from the company yet. But a couple of those   things are the diamond encapsulator,  which is the most thermally conductive   and hardest material available, in addition  to containing the radiation within the device. Next up is the Lock-in System, which helps  to prevent proliferation of dangerous nuclear   isotopes like Pu-238 and U-232. According to  NDB, their battery uses an ion implantation   mechanism that prevents it being used  for purposes other than power generation. Besides these safety claims, the company  says its technology has a maximum lifespan   of 28,000 years and could one day become a  source of low-carbon power for anything that   needs it – from EVs to smartphones. Although  this technology looks awesome, it's still   highly questionable since the power coming from  betavoltaics is so low. Remember, microwatts low. According to a report, the proof-of-concept design   was evaluated by the Lawrence  Livermore National Laboratory,   which reported a 40% charge improvement in  efficiency over a standard diamond. But I couldn't   find any information on how Lawrence Livermore  National Laboratory tested the proof-of-concept. Most of the claims have no hard evidence or  proof yet, other than what NDB has reported.   NDB doesn’t fully explain what happens to the  heat it generates during energy conversion   other than to describe thermal  vents to dissipate heat. The company mentions several possible applications  in their website like consumer electronics,   automotive, medical devices, aerospace, but we  still don't have precise specifications. Yet,   an image of the battery shows a power level of  100 microwatts. It's important to drive that point   home. It's highly unlikely to power an electric  vehicle, let alone an iPhone at microwatt scale.   But, it doesn't mean the tech doesn't work for  more appropriate applications. If enough of these   battery cells were combined, they could power  small LED displays or devices that require low   power, like medical or communication devices ...  think internet of things (IOT) and pacemakers. But   powering EVs that demand an insane amount energy  is where media coverage went a little overboard. So back in the land of reality   where do the benefits of this technology make  the most sense? And is there a market for it?

Well, the company hopes to start selling  the battery to commercial partners,   including space agencies for  long duration missions by 2023. In addition, NDB isn't alone in nuclear  diamond battery game. The scientists at Bristol   saw a great opportunity in extracting  and repurposing nuclear waste material,   but without overselling it. They spun  off Arkenlight, a company formed to   take on the commercialization of  their diamond battery concept. Morgan Boardman, the new company’s CEO says: “...It is a very novel approach, which we find   that people like because it’s sort of  a cosmic rag-and-bone man narrative...” He also points out that the technology can  help with the carbon emissions challenge: “...With the resources used to manufacture, say,  an AAA battery, we would offset nearly 2.5kg of   carbon in the manufacture of an equivalent  energy density of diamond batteries...” Unlike NDB, Arkenlight doesn't claim that their  batteries will power cars or even laptops. That's   because they provide thousands of times less  power than a conventional AA battery – although   they will last thousands of times longer.  Arkenlight’s power cells would take about   5,000 years to reach 50% discharge. The company  sees their batteries powering small detectors,   wireless IoT devices/sensors or medical implants. It can be mechanically stacked in  series or parallel for greater power,   and can be paired with capacitors for  intermittent high power use cases. In 2018, Bristol researchers did an interesting  experiment to test out the strength and durability   of their diamond batteries, placing them  at the top of a volcano. In the experiment,   a prototype of Arkenlight betavoltaics was used to  power sensors inside a remote-monitoring station,   known as a ‘dragon egg.’ The eggs were designed  to be placed on an active volcano by drone   in order to measure humidity, vibrations,  and the emissions of toxic gases.   They could remain in service for  months without depleting their energy. Arkenlight aims to establish a factory  at one of the several decommissioned   nuclear power plants in the South West of  England, or possibly North Wales. That way,   the company has easy access to carbon-14 isotopes  for battery manufacturing. Boardman estimates that   their carbon-14 batteries will begin appearing  in devices around 2024 if everything goes well. In terms of challenges, the use of radioactive  material complicates matters, so manufacturing   them involves a significant amount of care and  safety procedures you wouldn't have with a typical   chemical battery. While the process is made safe,  the safety infrastructure required to produce it,   and governmental permissions, come with big costs. Even though the researchers from both Bristol  University and NDB claim that nuclear batteries   have small or no radioactivity level due  to the diamond containment, I'm not sure   if I'd feel comfortable having a nuclear powered  cellphone even if it was possible at this point.   Putting aside the overhyped headlines, there's  still some interesting promise and use cases   for diamond batteries ... even though they're  still in their theoretical phase. We're going   to need to wait a few more years until NDB and  Arkenlight have some real prototypes and solid   results to call this one. Not every battery  technology has to be a lithium ion killer.   It's okay to have an exciting breakthrough for  a very targeted market, which is what this is. What do you think? Putting aside the overhyped  PR around this tech, do you think there's   something here? Is it worth keeping an eye  one?
