Job Description

The Bioenergy Science and Technology (BEST) directorate within the National Renewable Energy Lab (NLR) performs a full range of research from exploring biomass at the molecular level through biorefinery process optimization to bring biofuels and bio-products to market. The directorate's research encompasses multiple areas including biochemical processes, synthesis, processing, separations, analysis, and characterization.
The Separations Science and Engineering Group focuses on developing and scaling separation technologies for a wide range of molecules, from bio-derived and chemically synthesized products, through to critical minerals including rare-earth elements from domestic waste feedstocks. Our goal is to improve process efficiency, selectivity, and techno-economic viability and our work is conducted in close collaboration with fermentation, catalysis, polymer synthesis, and techno-economic analysis teams. The group emphasizes translating fundamental separation science into practical, scalable solutions.
This internship position is hiring for full-time work on-site with NLR's Separations Science and Engineering group. The successful candidate will support research efforts by contributing to laboratory-based separation experiments and custom separation equipment development including:
* benchtop wet chemistry and sample preparation
* chemical and/or protein purification
* multi-scale chromatography
* electrochemical separations
* assembly and modification of separation systems
* exposure to programming (e.g., python or rust) and support automation of custom separation systems
The ability to conduct laboratory experiments with minimal supervision, with the utmost regard to safety is required. Adaptability and an aptitude for learning are critical in this role. This is an excellent opportunity for a student invested in the NLR mission who desires relevant laboratory experience in preparation for graduate school or a career in the chemical industry.

About National Laboratory of the Rockies

Company Overview

Name

National Laboratory of the Rockies, a U.S. Department of Energy national laboratory

Headquarters

Golden, CO, United States

Founded

1977

Size

Approximately 3,700 employees including staff, postdoctoral researchers, interns, visiting professionals, and subcontractors (source: wikipedia.org)

What They Do

The National Laboratory of the Rockies is a federally funded research institution focused on applied energy research and development across the entire energy system, including generation, distribution, and end use (source: nlr.gov). Its work spans a broad range of energy technologies such as solar, wind, renewable fuels, vehicle systems, buildings, geothermal, energy sciences, computational sciences, and energy analysis (source: nationallabs.org). The laboratory also hosts specialized centers including the National Center for Photovoltaics, the National Bioenergy Center, and the National Wind Technology Center, which support focused research and innovation in their respective fields (source: wikipedia.org). As a Department of Energy national laboratory, it operates under a federal contract and serves public-sector and industry partners by developing technology and de-risking emerging energy systems (source: nlr.gov).

Projects & Track Record

The laboratory has a rich history of impactful projects, including the development of SEA-Stack, a wave-energy technology screening and design tool that helps companies rapidly evaluate concepts to reduce time and cost in marine energy innovation (source: nlr.gov). It also supports the BOTTLE Consortium's chemical oxidation recycling platform, which aims to enable scalable processing of contaminated, mixed, and multilayer plastic waste, addressing critical challenges in sustainable materials management (source: nlr.gov). The National Laboratory of the Rockies operates the National Wind Technology Center in Colorado, a key facility for advancing wind energy technologies, and maintains a presence in Washington, D.C. to support policy and stakeholder engagement (source: nlr.gov). These projects demonstrate the lab's leadership in renewable energy research and its commitment to accelerating clean energy solutions nationwide.

Recent Developments

In December 2025, the Department of Energy officially renamed the National Renewable Energy Laboratory to the National Laboratory of the Rockies, reflecting its evolving mission and regional identity (source: nlr.gov). Throughout 2025 and 2026, the laboratory remained active in advanced energy research, with announcements highlighting progress in marine and wave energy technologies, plastic recycling innovations, and quantum-related materials research (source: nlr.gov). However, the lab also underwent workforce reductions, laying off 134 employees in February 2026 following earlier cuts of at least 114 employees in May 2025, reflecting organizational adjustments amid evolving funding and program priorities (source: cpr.org).
