Blue Planet’s carbon capture & mineralization technology is a real world solution for CO2 mitigation. By mimicking nature’s process for hardening tissues in living organisms, our technology uses waste CO2 as a raw material to produce carbon-negative building materials. Our patented approach is both economically and ecologically sustainable.
Harnessing Osmotic Force to Generate Alkalinity
Wherever there is saltwater near fresh water, there is an untapped, universal and abundant power source. Osmotic pressure, the ultimate green energy – forms between salt & fresh water when they are separated by a membrane. The force created as the two achieve saline equilibrium can be harnessed to supply the thermodynamic work needed to generate alkalinity. Blue Planet’s alkaline solution is combined with CO2 from flue gas to form carbonates. By using osmotic force rather than electrolysis or electro-chemistry to generate alkalinity, Blue Planet can reduce parasitic load by up to 60%, and capital and operating costs by about 40%.
LCP™ Concentrate – A Scientific Breakthrough
Liquid condensed phase (LCP) droplets – nanometer-sized pockets of liquid that contain high concentrations of sequestered CO2 – are manipulated and isolated by Blue Planet using established water process technologies. A single feed solution containing LCP droplets is treated by nanofiltration, a low-energy alternative to reverse osmosis, which results in two output solutions; one is softened, nearly potable water, and the other is a concentrated solution of LCP droplets that Blue Planet uses for direct geomimetic mineralization of CaCO3.
Biomimetic & Geomimetic Mineralization
The White Cliffs of Dover are a visual example of earth’s process of converting CO2 into limestone, calcium carbonate (CaCO2). They are composed of carbon as calcium carbonate, safely stored for over 100 million years – representing about 10 billion tons of CO2. The Earth’s lithosphere contains approximately 70,000,000 billion tons of CO2 as carbonate rocks. This naturally occurring process forms the basis for the Blue Planet mineralization process.
High Reflectance (High Albedo) Products
Blue Planet’s products exhibit high solar reflectance (high albedo), which absorb less heat from the sun. Increasing solar reflectance by 30% can result in a 15% energy savings. Blue Planet’s CaCO3 has up to 96% reflectance and are ideally suited for use in cool-roof, cool-pavement, cool reflective pigment and exterior technologies. As backsheet in solar cells, Blue Planet’s ability to reflect solar light can dramatically increase solar cell efficiency. Due to its high quality and low cost, Blue Planet’s products can be used as TiO2 replacements or fillers. Blue Planet’s products can minimize the use of air-conditioning during hot summer months, helping to eliminate urban heat islands.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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
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)!
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.
