    CDR via algae biomass harvesting and usage
    2 weeks agoopen2
    This is the idea I presented at today's idea carousel. Rationale: On a yearly period, CO2 cycles back and forth from atmospheric gas to biomass back to atmospheric gas with an amplitude of ~5ppm = 5*8 = 40 Gt. Let's short-circuit this cycle when the CO2 in in the form of biomass and prevent as much of it to return to the atmosphere. Idea: A portion of the yearly carbon cycle is synthesized in the form of large algae blooms. Actually the extent and quantity of these blooms has been increasing over the past years, possibly related to various climate change factors. Idea would be to develop a fleet of autonomous self-powered boats that harvest these algaes before they are able to reach the beaches. Once harvested and processed (on the coast or on the ships), the large volumes of biomass can be turned into wanted co-products. Options includes the default bio-oil/bio-char, compost/fertiliser, and my personal favorite and most interesting insulating building block using mycelium. growth. Such a method of capturing and sequestering CO2 combines 3 benefits: 1/ capture carbon-rich biomass to prevent it from going back to air as CO2 gas. 2/ harvest large algae bloom biomass to prevent the harmful consequences that often comes with them (beaching, decomposition, methane emission, destroying coastal ecosystems and tourism communities) and 3/ producing useful co-products that have economic interest. One exemple of such a large algae bloom is sargassum.

    GreenCode: Software Decarbonisation at Scale
    4 weeks agoopen1
    GreenCode is (will be) an automated software decarbonisation pipeline and developer’s toolkit that leverages state of the art NLP practices and green (low-energy cost) generative AI techniques to reduce the cost and carbon footprint of software products and services, and by implication the wider ICT sector, while simultaneously boosting the productivity of development teams, and improving software quality and resiliency. This is a well-defined industry led (real applications) 3-year R&D project involving a consortium of leading universities/research organisations and business partners from around Europe that is in the final stages of signoff. I am looking to form a team (chief commercial officer and maybe chief technical officer (though I will always be close to the tech)) to help me commercialise it, as products emerge from the project from Jan 2025 (ish). Happy to answer questions, get feedback, have holes blown through it!
