Technology Overview

Blue Planet’s new biomimetic carbon capture and mineralization technology utilizes several patented scientific breakthoughs.

Products

Blue Planet uses it’s patented Liquid Condensed Phase (LCP™) Technology to convert CO2 into high-value CarbonMix™ building and highway materials.

Services

Blue Planet provides CO2 capture and sequestration, criteria pollutant removal, and water management services. We provide these services to emitters in the coal, gas, cement and refinery industries.

Sustainability

Blue carbon is captured naturally by marine ecosystems to build coral reefs. Blue Planet uses a similar mineralization process to convert CO2 into carbon negative building materials.

TECHNOLOGY

Unique, Efficient & Low-cost Carbon Capture Method

Blue Planet’s technology uses CO2 as a raw material for making carbonate rocks. The carbonate rocks produced are used in place of natural limestone rock mined from quarries, which is the principal component of concrete. CO2 from flue gas is converted to carbonate (or CO3=) by contacting CO2 containing gas with a water-based capture solutions. This differentiates Blue Planet from most CO2 capture methods because the captured CO2 does not require a purification step, which is an energy and capital intensive process. As a result Blue Planet’s capture method is extremely efficient, and results in a lower cost than traditional methods of CO2 capture.

How it Works: Process Flow


Synthetic Limestone Coating

The carbonated solutions formed from the captured CO2 are used to form a carbonate mineral coating over a nucleus or substrate. The carbonate minerals form a synthetic limestone coating. This permanently sequesters the captured CO2 as CO3= in the carbonate minerals comprising the limestone coating. The aggregate can be produced in different sizes, ranging from sand-sized to gravel-sized.

To reform our capture solution, it is exposed to a “Geomass”  which is our term for common rock waste and/or industrial waste materials that contain available alkalinity, which recharges the capture solution, and metal ions such as calcium, magnesium, and iron.  When the “spent” capture solution reacts with the Geomass, reforming it, these metal ions are released and combined with the carbonate solution to form the carbonate mineral coating.

Blue Planet Process is Similar to Ooid Formation in Nature


A rock particle is coated with our synthetic limestone, forming a carbon-sequestering coating that is 44% by mass CO2.The coating can contain residual fine particles from the capture solution regeneration.

44% (by mass) of CaCO3 Coating is CO2

PRODUCTS

Aggregates

Blue Planet produces lightweight coarse and fine aggregate, available for residential and commercial construction. Made from sequestered CO2 utilizing the biomineralization process, the use of Blue Planet aggregate is the most effective way to achieve carbon neutral and carbon negative concrete. Standard concrete, by comparison, has the highest CO2 footprint of all building materials.

Sack Concrete

Blue Planet bagged concrete is made of carbon sequestered coarse and fine aggregate. Until recently the only method for offsetting the carbon footprint of your building was achieved by planting trees. With Blue Planet sack concrete the highest CO2 footprint building material can now be carbon neutral or carbon negative.

Roofing Granules

When used in roofing tiles, Blue Planet’s roofing granules can reflect up to 96%, and up to 75% as shingles. Common asphalt roofing reflects only 10%. By reducing the absorption of solar heat, the use of energy for air-conditioning can be minimized during hot summer months.

Cool Pigments

When CO2 reacts with various transition metals, high solar-reflective cool pigments can be synthesized. These pigments used to color roofs and exterior walls will allow the building to absorb less heat from the sun, remaining cooler during hot summer months. An increase of solar reflectance by 30% using cool pigments can reduce energy costs by about 15%,

Titanim Oxide Replacement

Titanim Oxide (TiO2) is the most widely used white pigment. Due to its growing demand, the price of TiO2 is constantly rising. Blue Planet CaCO3 powder, which is 100x less expensive than TiO2, also exhibits a higher solar reflectance than TiO2. Due to biomimetic synthesis pathway, our CaCO3 is non-toxic, so it can be used in the pigment, food, beverage and cosmetics industries as a TiO2 replacement or filler.

Purified CO2

Because Blue Planet’s direct mineralization of CaCO3 mimics nature itself, purified CO2 is produced as a by-product at no extra cost. This is in contrast to state-of-the-art CCS technologies that require significant amounts of energy to produce pure CO2 as the only product. In Blue Planet’s technology, pure CO2 may be recycled in the process or sold to existing markets for enhanced oil recovery or geologic sequestration.

SERVICES

CO2 Capture

Blue Planet’s carbon capture and mineralization technology offers CO2 capture as an emissions control service to address existing and future CO2 cap-and-trade programs at state, federal and international levels.

Criteria Pollutant Removal

Of the U.S. EPA’s six criteria pollutants, which include ozone, particulate matter, carbon monoxide, nitrogen oxides (NOx), sulfur dioxide (SO2) and lead, Blue Planet’s carbon capture and mineralization technology will remove SO2 and lead. Under some circumstances, particulate matter may also be removed at specific sites equipped with the mineralization technology.

Water Management

Blue Planet uses three water inputs in its carbon capture and mineralization technology: (i) salty water, (ii) relatively less salty water and (iii) hard water. With pre-treatment, any combination of these waters may be obtained from the same input source, for example, produced waters at industrial sites. Once dissolved ions are consumed in the process, the treated water can be considered nearly potable.

Emitter Projects (Coal, Gas, Cement, Refinery)

Blue Planet is currently interviewing candidates for project demonstration. Potential sites include electricity generating stations powered by coal or natural gas, cement plants, petroleum and/or biofuel refineries.

SUSTAINABILITY

What is Blue Carbon?

Blue carbon is the carbon captured by the world’s oceans and coastal ecosystems. Most blue carbon is in the form of calcium carbonate skeletons of marine organisms like corals and other marine invertebrates and plants. Blue Planet’s process captures carbon dioxide in marine waters using a biomimetic process inspired by marine biomineralization forming calcium carbonate under very similar physical and chemical condition, using the same underlying fundament mechanism.

Blue Society

The Blue Society merges economic pursuits with environmental stewardship and sustainability. Carbon is viewed as a raw material that can be used to build a prosperous and sustainable society. The common legal principle that ‘polluters will pay’ through regulation and tariffs transforms into the principle that ’producers will prosper’. Carbon dioxide will no longer be dumped into the atmosphere or stored underground. Instead, carbon dioxide will be the raw material for the sustainable built environment, mimicking biological structures like the Great Barrier Reef.

Sustainable building

Blue Planet’s products contribute to green building in both embodied energy and energy efficency, by providing an alternative to aggregate.

“The health and integrity of coastal habitats – such as coral reefs, wetlands, mangroves, salt marshes and sea grass beds – are key to sustaining our Nation’s valuable coastal and ocean ecosystems and the wealth of benefits they provide to us. … they capture and store carbon…”
– United States National Ocean Policy

CarbonStar

Blue Planet’s Government Affairs team is working with global leaders in the green building industry to develop a simple way to communicate the carbon footprint associated with concrete. The CarbonStar rating is a metric based on the embodied mass of CO2 in a unit of concrete. Of the three components in concrete – water, cement and aggregate – cement is by far the most significant contributor to CO2 emissions, roughly 1:1 by mass (1 ton cement produces roughly 1 ton CO2). So, if a cubic yard of concrete uses 600 lb cement, then its CarbonStar rating is 600. The idea is to get the CarbonStar rating as low (or negative) as possible. One approach to lowering the CarbonStar rating for a cubic yard of concrete is to replace traditional aggregate with Blue Planet aggregate. The difference? Blue Planet aggregate contains sequestered CO2 that, when used in place of traditional aggregate, will reduce the CO2 footprint in a yard of concrete by over 1,800 lb CO2, resulting in a CarbonStar rating of -1,200 (assuming 600 lb cement & 3,100 lb aggregate)!

Energy Efficiency

Applying high solar-reflectance roofing & pavement can save $1B per year in net US energy costs. This results in less energy use and reduced CO2 emissions. Applying cool roofs and cool pavements together can offset approximately 44 gigatons of CO2 worldwide (at a value of $1100B). Because Blue Planet captures and utilizes CO2 for synthesizing its products, the total CO2 offset far exceeds 44 gigatons.
